APOD 2.6

As if the Aurora Borealis wasn't beautiful enough, taken through a long exposure shot over a pretty lake really adds to the sheer beauty, along with giving a glow to the entire area around it. But to further capitalize on it, the long exposure ended up capturing a Geminid Meteor, fireball specifically, go streaking across the sky. Tearing through the Big Dipper gave off a stunning and dramatic shot. Amazing what 30 seconds of exposure, charged particles in the magnetosphere, and absolute perfect timing can do and create.

APOD 2.5

Yet another wonder of the night sky, Eta Carinae is an expanding nebula formed by unknown forces from its star system form. This Homunculus Nebula is a complete mystery of formation, but also is a beautiful wonder as over the past 170 years it has grown brighter, faded, brighter again, etc. in 1995 it actually became the second brightest star system in the sky.  Shown over three pictures is it actually not only brightening and dimming, but also it having amazing streams of light shooting out amongst the gas clouds that are expanding from the central massive star. Still exploding randomly even now, it is expected that this system will eventually cause an amazing supernova. Eventually.

APOD 2.3

This galactic anomaly known as NGC 660 is a fantastic example of a grand speculative concept. Known as a Polar Ring Galaxy, these are extremely rare clusters that form likely from the brushing by of two galaxies, essentially capturing material from a passerby and then turning that material into orbiting solar systems and thus forming a ring. Kind of like an exponential Saturn in concept. Whats interesting is the fact that these rings are almost perfectly perpendicular to the galaxy itself. the polar ring itself is actually based with the concept also of a Dark Matter ring/halo of which can also actually be measured in mass. Overall this is a very unique Galactic formation that is a sure thing to keep in mind for future study.

APOD 2.2

A very rare sight indeed, a view of a ultra thing galaxy, NGC 4762, can be seen nearly perfectly on its edge, really demonstrating just how flat a galaxy can be. The reason this particular image, taken from the Hubble, is so rare is due to the fact that in order for us as humans to perceive this view requires our Earth to be nearly perfect on the plane of the galaxies line. Granted there are plenty of other galaxies as flat as this one, our own for example, but the fact that this one is perfectly perpendicular to our planet is a crazy sight to see. NGC 4762 is actually located in the Virgo Cluster of Galaxies and is about 100,000 Light years from end to end, thus truthfully capturing the scale of how big this galaxy is and yet at the same time how insanely thin it is.

APOD 2.1

Black holes have been a topic of fascination ever since they were first discovered, as the concept of an object of infinite density just was simply astounding and almost impossible to comprehend. These days with such high level technology, we can see actual black holes in space, but even now that brings up only more questions and curiosity. In this picture there is a black hole which is simulated in a computer, and as one can see, it does weird things to its surrounding environment. Since it is infinitely dense light is actually pulled toward it which means everything we see around the black hole is warped and distorted. Some say that black holes are so strong that they are actually what holds galaxies together, that everything spins around giant black holes that inevitably are swallowing everything up. Crazy as it may be, even though we can technically simulate a black hole, everything about it is still just theory, and we may not know much about them at all for a long time.

APOD 1.8

Saturn's moon Titan  has no doubt been an anomaly since the day it was discovered, mostly due to the  fact that it's surface is a hydrocarbon sea surrounded by a cloud of methane and ethane. Thus, being a source of strange interest it naturally has a satellite that has been taking pictures of it's surface for awhile. What's odd is that within one of it's lakes, known as Ligeia Mare, an object appeared back in 2013 on July 10, out of nowhere and has remained there now for a year, but yet upon further review has actually changed. Being 20 km in length, scientists really aren't sure what it is exactly though much speculation has been put in pertaining it. Some believe it to be some sort of bubbling foam, or an odd cluster of floating solids, but again no one really knows what it is. Deeper observation may reveal what it is at some point... But more than likely just bring up more questions, and since we cannot have someone or a robot to go and see up close and personal and bring a sample back, we will likely never know exactly what it is.

Biography


Georg Von Peuerbach
            Georg Von Peuerbach was an Austrian astronomer and mathematician of whom was key in the revival of the geocentric model of cosmetology known as the Ptolemaic system. Born in Peuerbach, Austria in 1421, Georg was not really put onto the theoretical radar until about 1446 upon which time he had entered the University of Vienna. Not two years later was he on the road across northern Italy, lecturing on astronomy in places such as Padua. He travelled from 1448-1451 before returning to the University where he got a masters in arts and taught Latin poetry. Though to be honest, no one really took note of his poetic interests. Of course, it does help being the court astronomer, on a few different occasions. Such as his first position with King Ladislas V around 1457, which of course led to him working under his uncle who was the Holy Roman Emperor Frederick III. Together with his student Johannes Muller, he observed multiple interesting observations including some lunar eclipses and two comets which included Halley’s comet. But in the end, Georg will always be best known for his book the Theoricae Novae Planetarum which he wrote in 1454, translating to New Theories of the Planets. This book, interestingly enough, actually started as notes taken by Regiomontanus during his lectures at the Viennese Citizens’ School. This book was so popular in fact, that it actually ended up replacing the former textbook Theorica Planetarum Communis or the Theory of the Planets, which had been widely used in the field of Astronomy for a very long time.

            Now, by the 17th century, the New Theory of the Planets had become the textbook standard. It had been made into more than 50 Latin and vernacular variants, and distributed far and wide. It even gave notable figures such as Copernicus and Galileo better and more simplified explanations of the Ptolemaic system. It also helped giving Ptolemy’s Almagest a better physical interpretation of his complicated mathematical problems and models. Beyond that, Georg also created the Tabulae Eclipsium around 1459, which was an amazing set of eclipse tables, which ended up becoming another widely used and respected text. And in the end, his best achievement of all was the fact that he was able to keep all of this relatively simple, restricting it to things like sine tables and basic arithmetic, along with enabling the ease of use of the calculating devices while constructing some of his own, like quadrants, astrolabes and gnomons. This man influenced us, some of the astronomical giants in history, and astronomy in general, helping bridge the gap between the average person and the understanding of space and its structure.

APOD 1.7

Behold, the temples of the Sun and the Moon, connected by the inseparable bridge that is the Milky Way. From this view one can witness everything from the Summer triangle of Deneb, Vega and Altair to an actual galaxy, Andromeda to be specific, along with a few other Messier objects and constellations. Taken in Capitol Reef National Park in Utah, the two stone monoliths stand a mighty 100 meters tall and have lasted for over 160 million years. A beautiful example of what can be seen in complete darkness, this multi-image panorama is definitely a sight to behold.

APOD 1.6

In the Abell 400 cluster of galaxies, 3C75 is a sight to behold. The slow collision of two supermassive blackholes can be viewed via the enhancement of colored x-rays and radio waves, as seen below, and forms a spectacular sight of unimaginable power and size. They are bound in what is known as a binary system, and are each traveling at mind boggling speeds of about 1200 kilometers per second.  Their eventual collision, though not likely to be seen in our lifetime, are in theory sources of what could be intense amounts of gravitational waves, causing possible ripples in spacetime. Which is nuts. Luckily we wont have much to worry about at that point since the binary system is located about 300 million light years away, but it is still an amazing concept that there even is a source that actually bend spacetime, what we essentially call reality

APOD 1.5

Saturn, a long known solar object in our system for hundreds of years, but even with how long humans have been observing it, and how far technology has come, we still have many things to discover about it. Such as not until the August of 2009 had we ever observed or had a picture of Saturn at its Equinox. The main issue being that, since Saturn's rings during its equinox point almost exactly at Earth while also at the sun, they usually just seem to disappear, so we have never had a chance to view all of Saturn during its equinox. But thanks to Cassini, the flagship satellite by NASA which was sent to Saturn in 1997, we now have a photo/ multiple photos of what Saturn's whole self looks like during its equinox. It is a surreal sight seeing the darkened rings, and the dramatic shadow cast behind the planet, and a humble reminder that even up to our modern years, we have much to learn and find out about the heavens above.

APOD 1.4

Potentially Habitable Moons

The concept of finding extraterrestrial life, or just finding another place in the universe to habitat has always been a fascinating study, a study known commonly as astrobiology. This study of finding new life and living places has led to new research suggesting that not only are there many moons that are easily inhabitable, such as Europa, Ganymede, etc but that there actually may be more inhabitable moons than there are inhabitable planets in the universe, at least within the stellar habitable zones that is. This concept was further emphasized just simply by observing certain moons within our own solar system alone, such as Europa, of which has a surface of majority water, like that of Ganymede's. Or from Enceladus, of which has water erupting from its surface in a warm climate. These examples show that, if we have this many in only our solar system, imagine just how many may be inhabitable in the entire universe. This leads to a likely expectation of more exomoon exploration in the future.

APOD 1.3

Auroras, beautiful displays of color in the sky caused by the plasma clouds emitted by our sun impacting the magnetosphere with ionized particles. Even more uncommon is a double auroral, which are sheets of auroras combined but yet separated. These seperations, or curtains, are caused by black auroras, or anti-auroras between the curtains. These are quite literally caused by the opposite effect of normal auroras, as they are negatively charged particles that are sucked out of Earth versus toward it along magnetic fields. In this specific photo, the Milky Way galaxy is seen right above the aurora, adding to the overall beauty of this peace located above a pretty city in Sweden.

APOD 1.2

Over Bangledesh in Tibet, China a large airglow appeared shining various colors in a target formation. This spectacular demonstration of chemiluminescence is caused by a combination of various chemicals and waves in the air, but this particular one was caused by gravity waves. Gravity waves are caused by air pressure raising air, but gravity pulling it back down. This scenario, like all airglows, can only happen over 80,000 kilometers above, or in this case, 90,000. And unlike Auroras which are the electrical variants of airglows, these are given their color by chemicals in the atmosphere, combined with gravity waves to give it the ripple effect.

APOD 1.1

          The Trifid Nebula is a stunning star and dust cluster about 5400 lightyears away from Earth contained within the Sagittarius constellation. Known as Messier 20 and 21 (For the younger cluster of stars next to it), it consists of three different variants of nebula, including absorption, emission, and reflection. These mashups are known as stellar cauldrons, similar to the Lagoon Nebula, and they are known to be stunning due to all the colors that are caused by the light being effected by the bits of stellar dust and gases surrounding them. As for Messier 21, that is a smaller nebula in the making, an embryo of sorts, of which is one of the smallest stellar systems at only 300,000 years old. These are also great things to view for up and coming astronomers as these are some of the easiest systems to spot in the night sky, and again conveniently located within Sagittarius.
