Night Sky Photography -- 08-31-2023 -- The Super Blue Moon & Orion Stars In Early Morning Hours

Good morning, fellow stargazers!

Today I had to wake up extra early -- about just over 90 minutes before sunrise in fact -- to capture my photographs of the second Full Moon and third Supermoon of August, 2023: the Blue Supermoon, or Super Blue Moon.

The reason I had to wait till the early hours to take the shots was due to extensive cloud cover from summer thunderstorms brought about as a result of the recent hurricane in the Gulf of Mexico. Thankfully those storms moved off about 5 AM Eastern Standard Time (EDT) and gave way to perfectly clear early morning skies, as you can see in my first shot.

Currently, the Super Blue Moon is 222,043 miles (or 357,344 kilometers) from the Earth, making it the closes of the four Supermoons this year -- which is why I was thankful to be able to capture some great photos of it.


The next two photos are close-up of the features of the Super Blue Moon showing all the larger craters and the dark gray "seas" on the visible Lunar surface that we see here on the Earth.

My final Full Moon photo is a wider shot of the Super Blue Moon along with the planet Saturn just above the tree lines.



Since I was up so early I turned my camera to the eastern sky where the Constellation Orion The Hunter was making his way back into the early morning sky.

In my final two photos I was able to capture all the major stars of Orion, as well as the nearby bright stars Aldebaran and Procyon.


That concludes my night sky offerings for the month of August 2023. I hope y'all enjoyed my photos as I continue to enjoy posting them for y'all.

Have a wonderful Dixie Day and y'all be sure to keep your eyes to the night skies.

Earth Is A Bright Evening "Twin Star" As Seen From Mars

Earth and the Moon as seen in the Martian night sky photographed by NASA's Curiosity rover at Gale Crater
on Friday, January 31, 2014 about 80 minutes after local sunset
during its 529th day on the Martian surface.
The Moon is only barely visible just below the bright Earth in close-up.

Imagine you were a human settler living on the planet Mars, the forth planet in our Solar System, in possibly as few as a couple hundred years from the present day.

You're walking outside the pressurized habitats built by the first and second generations born on Mars -- or possibly even domed terrariums as the first stages of the long process of terraforming the Red Planet are just beginning -- and stand out on the surface looking up at the evening sky.

Its about an hour following the beautiful blue Martian sunset in the crimson sky over the slightly closer horizon of the vast rust-colored desert planet and the first of the brightest objects appear overhead.

First would be the two moons: the larger, potato-shaped Phobos, and the smaller bright Deimos (both of which are also visible during the daylight hours). After these would come the first bright spots low in the evening sky -- our own planet Earth and its faint companion, our bright, beautiful Moon. 

On average the distance between Earth and Mars is about 140 million miles (or 225 million kilometers). From the surface of Mars, a hypothetical Martian would see our Earth the same way that we Earthlings view the planet Venus: as an inner planet, because Earth is in a closer and faster orbit to the Sun. Because of this, Earth, as seen from Mars, appears as a bright morning or evening "star" as Venus does here on Earth.

Also, from the surface of Mars, our lovely Luna (Moon), though appearing very faint, can actually be seen with the naked eye (or more likely through the safety glass plate of a pressure suit).

Because our Moon only averages a distance of about
238,855 miles (or 384,400 kilometers) in its orbit around our Earth, from the surface of Mars looking up into the night sky dome, Earth and the Moon would only appear to be separate by less than a degree (or, roughly just under the length of your pinky finger held at arms length) most of the time. So close together that the two heavenly bodies appear to be constantly in conjunction with one another, appearing to be a "twin star" in the evening and morning Martian skies.

A hypothetical Martian would also be able to see the Moon orbit the Earth, even see both heavenly bodies transit each other (pass in front of, or behind, the other) at certain times of the long Martian year in their orbit.

Thanks to modern science, we are able to view that magnificent sight or our home planet from another world right here from Earth via photographs taken from the surface of Mars by exploration rovers sent by us humans to study the possibility of human exploration (and possible future colonization) of our closest planetary neighbor -- as shown in the photo used for this article.

Through the yes of these robotic explorers we can see our own Earth and its beautiful Moon in a way that early humans looking up at the night sky could never have imagined; that only God, and perhaps maybe non-human intelligence beyond our Solar System, could ever have seen humanity's home before.

All the same, maybe someday soon Earth-born explorers in the coming decades -- and perhaps future generations of Martian-born humans hundreds of years from now -- will see that beautiful sight of our lovely Earth and Moon from the surface of the Red Planet with their own eyes with that same sense of wonder that us night sky observers here on Earth view the other planets in our Solar System?

Night Sky Photography -- 08-11-2023 -- The Summer Triangle & The Northern Cross

Good evening, fellow stargazers! 

Now that we're well into summer here in the Northern Hemisphere, the three bright stars that make up the 
Summer Triangle asterism can easily be spotted overhead late in the evenings.

The three bright first-magnitude stars: Vega, Deneb, and Altair are all easily visible to the naked eye and make up the brightest stars of their respective star constellations. Vega is the brightest star of the small Constellation Lyra the Harp. Deneb is the brightest in the Constellation Cygnus the Swan. Altair is the brightest star in the Constellation Aquila the Eagle.

I captured a good pair of shots outlining the bright stars that make up the vertices (or corners) of the Summer Triangle, as well as the major stars of the three star constellations that make up the asterism. I highlighted the constellations as well as the two asterisms that make up both the Summer Triangle and the Northern Cross respectively.




Here are some interesting facts about the three main stars in the Summer Triangle and the Northern Cross. 

Altair, in the Constellation Aquila, is a A-type main-sequence star only about 16.7 light-years (or 5.1 parsecs) away from our Sun, making it one of our nearer interstellar neighbors. 

Vega, in the Constellation Lyra, sits only 25 light-years (or 7.7 parsecs) away and is the 5th brightest star in the night sky -- the second-brightest star in the northern celestial hemisphere after Arcturus

Deneb, in the Constellation Cygnus, is the 19th brightest star in the night sky and the head of the Northern Cross. The bright blue-white supergiant star is believed to be somewhere around 2,615 light-years (or 802 parsecs) distant from our Earth and estimated to be around 200,000 times as bright as our own Sun! This makes Deneb one of the most distant stars visible from Earth with the naked eye.

The Northern Cross itself consists of the six brightest stars in Cygnus: Deneb, Sadr, Gienah, Delta Cygni, and Albireo.
Albireo appears at the head of the Cygnus the Swan, and serves as the base of the Northern Cross.

Well folks I hope y'all enjoyed my photos. Be sure to leave a comment below and have a wonderful Dixie evening, and be sure to keep your eyes to the night skies, y'all!

What Is A Blue Moon And How Rare Are They?



Later this month, on the night of August 30-31, 2023, there will be a Super Blue Moon -- the second Supermoon of August in fact. Luna (aka Earth's Moon) will be very close to the Earth and appear along with the planet Saturn. It will also be the last Full Moon of the summer season of 2023.

How rare are Blue Moons? Well, the classic phrase "once in a Blue Moon" referring to a rare occurrence aside, Blue Moons take place in years when there are 13 Full Moons in a calendar year.
The Full Moon phase occurs every 29.5 Earth days. Because of this Blue Moons occur about once every two to three years on average, although sometimes they can occur in the next year during leap years -- as will be the case in 2024, which will also have a Blue Moon in the month of August.

Although the term Blue Moon nominally refer to the second Full Moon of a single calendar month, there are actually two types of Blue Moons: a monthly Blue Moon and a seasonal Blue Moon.

The monthly Blue Moon meets the traditional definition of the second Full Moon in a single calendar month, while a seasonal Blue Moon is the third Full Moon in a season that has four Full Moons.

The Blue Moon of August 30th will be a monthly Blue Moon, since there will only be three Full Moons in summer of 2023. The next Blue Moon will take place next year -- a leap year -- on the night of August 19-20, 2024, will be a seasonal Blue Moon since there will be four Full Moons during that year's summer season:
June 21st (on the summer solstice), July 21st, August 19th, and September 18th.

Finally, the term Blue Moon does not actually refer to the color of the Lunar surface itself. Moons that appear blue (such as the one in the photo above) are incredibly rare and have nothing to do with the calendar or the Moon's phases. Such coloring is usually a result of certain atmospheric conditions: smoke, dust, or even water droplets in the atmosphere from certain types of clouds can all contribute to a Full Moon taking on a blue shade on rare occasions.

Fun Full Moon Fact:
The month of February will never experience a monthly Blue Moon as it only has 28 days in a common year and 29 in a leap year. Sometimes February doesn't have a Full Moon at all and this is known as a Black Moon -- which will not happen again till February of 2037.

Night Sky Photography -- 08-08-2023 -- Last Quarter Moon & Jupiter with Galilean Moons



This afternoon and early evening we had some more of those hit-and-run thunderstorms that our little corner of Dixie is famous for in the summer months, as well as cloud cover, which thankfully cleared up just after midnight.

I was up kinda late and was able to capture some outstanding late night photos of the Last Quarter Moon in the night sky, along with the planet Jupiter and its four largest moons about 90 minutes after moonrise in the eastern sky.

As you can see from my first photo, the position of the Last Quarter moon with the Earth's shadow across the half of the beautiful Lunar surface is almost perfectly in line with the position of Jupiter just below and to the right of our view here on Earth. In the second close-up photos you can see the details of our lovely Luna's surface evenly covered by the Earth's shadow across the face of the Man-In-The-Moon.



In my third and fourth close-up photos, y'all can make out the bright planet Jupiter and its four famous Galilean (Jovian) satellites: Io, Europa, Ganymede, and Callisto; all of them just below Luna with the heavenly bodies separated at about 2 degrees (or about three full moon widths) apart. 

The the present time Jupiter is currently 444.8 million miles (about 722.4 million kilometers, or 4.8 AUs) from Earth, with the light from both the gas giant planet and its moons taking about 40 minutes to reach us here on the Earth's surface.




With my final four shots of the evening I captured some beautiful wide shots with the Last Quarter Moon and Jupiter with the fast-moving clouds moving past them overhead. Overall, a really good series of photos for the evening (or early morning depending on how y'all look at it). I truly hope y'all enjoyed them as much as I enjoy presenting them to y'all.

The Life And Death Of Brigadier General Maxcy Gregg C.S.A. (1814 - 1862)

Brigadier General Maxcy Gregg, C.S.A.
(August 1, 1814 - December 15, 1862)

Maxcy Gregg was born on Monday, August 1, 1814 in Columbia, South Carolina to the city's mayor, James Gregg (1787-1852) and his wife, Cornelia Manning Maxcy Gregg (1792-1862).

His family history tells that his maternal great-grandfather was Commodore Esek Hopkins -- the first commander-in-chief of the Continental Navy (1775-1785) during the American Revolutionary War (1775-1783). His maternal grandfather was Jonathan Maxcy (1768-1820), the first president of the University of South Carolina (USC). His paternal great-grandfather, John Gregg (1732-1775), was an Ulster-Scots immigrant who settled in South Carolina in 1752 and became one of the American progenitors of the Gregg family. His great-uncle, James Gregg (1752-1802) served as a Patriot captain in the Southern Campaign of the Revolutionary War under Brigadier General Francis "Swamp Fox" Marion

As a young man known to have a keen intellect, Maxcy Gregg attended South Carolina College (later USC) and studied astronomy, botany, ornithology, and languages among other intellectual pursuits. He graduated
co-valedictorian of his class in 1836 and would study law and be admitted to the South Carolina bar in 1839. He would practice the law with his father, becoming a very well respected member of Columbia society. The scholarly scientist-lawyer also owned his own small private observatory at his home so well equipped it would have been coveted by many colleges. 

Gregg's first military experience came when he was commissioned a Major in 
Milledge L. Bonham’s 12th U.S. Infantry Regiment in the American-Mexican War (1846-1848), however, he did not arrive in time to participate in any of the major battles of the war.

He was also a life-long bachelor and never married.

For two decades -- with only his duty in the Mexican War as an interruption -- Maxcy Gregg was extensively involved in State and regional politics. Gregg was a strong advocate of States' rights his entire life, one of the original Fire-Eaters, and a major supporter of Robert Barnwell Rhett (1800-1876), the "father of secession".
He was a member of the Southern Rights Convention of 1852.

Gregg was a major proponent of secession prior to the commencement of the Civil War. In 1858, he issued the secessionists' manifesto in a pamphlet entitled, "An Appeal to the State Rights Party of South Carolina." In it, Gregg argued that Carolinians had looked unfavorably upon and rejected incorporation into the Democratic Party since the tariff controversy.


He served a delegate from the Richland District (Richland County) to the 1860 Secession Convention, voting to leave the Union on Thursday, December 20, 1860 and assisted in writing the Ordinance of Secession.

Gregg helped organize the 1st South Carolina Volunteers, and served as the regiment's first colonel. This regiment was authorized for six months by the State of South Carolina and the volunteers participated in the bombardment of Fort Sumter in Charleston Harbor on Friday, April 12, 1861.
Part of this unit was under fire during the bombardment, but took no casualties.

When the State of Virginia seceded, the regiment moved north, where they spent the spring months drilling and picketing. When their term expired on July 9th of that year, many members of the regiment returned to their homes, missing the First Battle of Manassas  on Sunday, July 21, 1861.


Gregg and other officers recruited another 1st South Carolina Infantry Regiment (also known as "Gregg's First South Carolina") that August.
With the newly formed 1st South Carolina, he was ordered to the Suffolk, Virginia, area in autumn 1861. On Saturday, December 14, 1861 he received his commission promoting him to the rank of Brigadier General.

Museum, Columbia, South Carolina.

In May of 1862, General Gregg's brigade was assigned to a division of the Confederate Army of Northern Virginia (ANV) under the command of Major General Ambrose P. Hill.  Gregg's brigade consisted of five South Carolina regiments: his own 1st South Carolina Infantry, the 12th, 13th and 14th South Carolina Infantry Regiments, and
the 1st South Carolina Regiment of Rifles (also better known as "Orr's Regiment of Rifles").

During the Seven Days' Battles around Richmond, General Gregg's South Carolinians played a prominent role in General Hill's assault on the Union lines at the Battle of Gaines Mill (Friday, June 27, 1862). The advance of Gregg's five South Carolina regiments was, according to General Hill, "the handsomest charge in line I have seen during the War."

The South Carolina brigade would suffer 939 casualties -- more than any other brigade in A.P. Hill's Light Division during the Seven Days Battles.

The 1st South Carolina lost lost 20 killed and 133 wounded -- including their lieutenant colonel who was killed.
Orr's Rifles lost 81 killed and 234 wounded. The 12th South Carolina lost 17 men killed and 121 wounded -- including their colonel. The 14th South Carolina lost nearly half of the 500 men engaged in the battle, including a major and two captains who were wounded. Most of these casualties took place at Gaines Mill.

Gregg’s brigade, along with the rest of Hill's Light Division, served in Lieutenant General Thomas J. "Stonewall" Jackson’s Corps at the Second Battle of Manassas (August 29-30, 1862).

During the first day of the battle on Friday, August 29th, Gregg walked along the brigade's line, fearlessly exposing himself to enemy fire and encouraging his men to hold their ground near an abandoned railroad cut. The brunt of the Federal attack fell on Gregg's brigade, which had defended against six Union assaults over an eight hour period that day. During one of these attacks, Gregg sent a message saying: "Tell General Hill that my ammunition is exhausted, but that I will hold my position with the bayonet!"

The brigade was nearly out of ammunition in addition to having lost most of its officers, many of the South Carolinians resorting to throwing stones from the railroad cut at the advancing Federals. As they fell back onto the edge of a hillside to regroup, Gregg lopped some wildflowers with his great-uncle's old Revolutionary War scimitar and remarked, "Let us die here my men, let us die here."

In their defense of the railroad cut, Gregg's Brigade suffered among the highest casualties -- about 613 men killed and wounded.

The 1st South Carolina Infantry lost 53 percent of the 233 men engaged. Orr's Rifles lost 116 men -- including its command officer and second in command killed. The 12th South Carolina lost 146 men out of 270 with three of its major officers wounded. The 13th South Carolina lost 26 killed and 118 wounded with its colonel wounded. The 14th South Carolina lost 8 killed and 57 wounded (among the wounded both their colonel and lieutenant colonel).


The South Carolina brigade also fought at the Battle Of Ox Hill (Monday, September 1, 1862) in pursuit of the retreating Union forces following the Confederate victory at Second Manassas. The Light Division drove back a Union assault during a driving rain.

In General Robert E. Lee's Maryland campaign, Gregg’s brigade participated in the capture of Harper’s Ferry (September 15, 1862) and then made a forced march to Sharpsburg, Maryland, arriving in the middle of that battle to take a place in the right center of the line, where it joined the fighting that afternoon and, along with the rest of Hill's Light Division, checked the final assault of the Union forces and saved the rest of the Army of Northern Virginia from total defeat.

It was at the Battle of Sharpsburg (Antietam Creek) on the afternoon of Wednesday, September 17, 1862 where General Gregg was slightly wounded in the thigh by the same Union volley that killed North Carolina born Brigadier General Lawrence O'Bryan Branch. Gregg would miraculously discover the spent minieball in his handkerchief the next morning at breakfast. His brigade arrived in time to save the Confederate flank and would be the last Confederate brigade to recross the Potomac River following the end of the Maryland Campaign.

After two months of recuperation at camp near Winchester, Virginia, the brigade participated in the Battle of Fredericksburg on Saturday, December 13, 1862 on Stonewall Jackson's position on the right of the Army of Northern Virginia. Gregg's Brigade held a reserve position behind the rest of the Light Division.

Unknown to General Gregg and his men, the Light Division's defenses in the thickly wooded position had a dangerous gap that was exploited by Union forces under Union Major General George G. Meade.

Gregg's Brigade was taking cover from the Union artillery and most of them still had their arms stacked when the Federals appeared. Because of the confusion and the foggy conditions in the thick underbrush, Gregg misidentified the advancing Union soldiers as retreating Confederate pickets and ordered his South Carolinians atop a ridge to hold their fire. This would be a fatal mistake as the Yankees open fire.

General Gregg attempted to rally his surprised men and try to lead them in a counterattack to close the gap in the line. Riding toward the front, Gregg was struck by a rifle ball that entered his right side from the back and severed his spinal cord, leaving him paralyzed from the waist down.

Brigadier General Maxcy Gregg succumbed to his agonizing injury two days later on Monday, December 15, 1862, reportedly saying on his deathbed: "I yield my life cheerfully, fighting for the independence of South Carolina."


He was 48 years old at the time of his death.

Gregg's loss weighed especially heavy on his commanding officer, General A.P. Hill, who stated: "A more chivalrous gentleman and gallant soldier never adorned the service which he so loved." According to the Wednesday, December 17, 1862, issue of the Richmond Daily Dispatch, his remains received a hero's welcome in the Confederate capital.

Prior to General Stonewall Jackson’s death in May of 1863, he said of Gregg: "General Gregg was a brave and accomplished officer, full of heroic sentiment and chivalrous honor.  He had rendered valuable service in this great struggle for our freedom, and the country has much reason to deplore the loss sustained by his premature death."
 
Regarding the untimely death of Maxcy Gregg, Robert E. Lee wrote to Governor Pickens as follows:

CAMP NEAR FREDERICKSBURG, December 18, 1862.
His Excellency FRANCIS W. PICKENS,

Governor of South Carolina:

SIR: While South Carolina is mourning the loss of the gallant and distinguished son, General Maxcy Gregg, permit me to join in your sorrow for his death. From my first acquaintance, when you sent, him with his gallant regiment to the defense of our frontier in Virginia, I have admired his disinterested patriotism and his unselfish devotion. He has always been at the post of duty and of danger, and his services in this army have been of inestimable value, and his loss is deeply lamented. In its greatest triumphs and its bloodiest battles he has borne a distinguished part. On the Chickahominy, on the plains of Manassas, at Harper's Ferry, Sharpsburg, and Shepherdstown he led his brigade with distinguished skill and dauntless valor. On the wooded heights of Fredericksburg he fell, in front of his brigade, in close conflict with the advancing foe. The death of such a man is a costly sacrifice, for it is to men of his high integrity and commanding intellect that the country must look to give character to her councils, that she may be respected and honored by all nations. Among those of his State who will proudly read the history of his deeds, may many be found to imitate his noble example.

I have the honor to be, with great respect, your obedient servant,
R. E. LEE,
General.

Night Sky Photography -- 08-01-2023 -- The First Of Two Supermoons In August 2023!

Good evening, y'all!

Last night, after several nights of the surprise hit-and-run rainstorms common for summers down her in my corner of Dixie, and overcast skies, we finally managed to have clear semi-clear skies....and just in time for the first of two full moons in the month of August, 2023.


This year both this evening's Full Sturgeon Moon -- the name for the August full moon in North America -- and the Blue Moon of Wednesday, August 30th are Supermoons!

This evening, the Full Sturgeon Supermoon is approximately 222,158 miles (or, 357,530 km) from the Earth.

In the wider night sky shot you can also see the planet Saturn near the Full Moon. I thought the moonlight with the nearby clouds came out quite beautifully with the giant ringed planet a small, bright dot nearby.
Saturn is currently 820,817,683 miles (1,320,978,013 kilometers, or 8.8 AUs) from the Earth. Saturn is currently located inside the Constellation Aquarius.

Saturn will also be present with the Blue Supermoon on August 30th and appear much closer. I'm praying for clear skies so that I can photograph them that evening.
