Constellations

...down by the International Astronomical Union (IAU). These areas mostly had their origins in Western-traditional asterisms from which the constellations take their names. When astronomers say something is “in” a given constellation they mean it is within those official boundaries. There are 88 officially recognized constellations, covering the entire sky[1] which have grown from the 48 classical Greek constellations laid down by Ptolemy in the Almagest. Out of these 88 constellations, 12 compose the zodiac signs. Thus, any given point in a celestial coordinate system can unambiguously be assigned to a constellation. It is usual in astronomy to give the constellation in which a given object is found along with its coordinates in order to convey a rough idea in which part of the sky it is located.

Astronomy Then and Now

...Astronomy: Then and Now Have you ever heard the saying you can’t teach an ole dog new tricks? What about the one where three old dogs teach new tricks? I’m sure you have heard that one, anyone who knows about our solar system can thank the three old dogs. Well, they’re not dogs at all, and at their time they weren’t old but in our time their long gone. Of course, I am speaking about Ptolemy, Copernicus, and Kepler. Funny thing is each one of them challenged and changed their predecessor's work, for the better of course, but we will get to that later. We have these three men to thank for a whole lot of new tricks. To name a few would be, our solar system, the way we form our maps, and we can’t forget the numerous mathematical formulas used to make ideas come to life. In this research paper, we will touch base on the lives of three great astronomers and the tricks they have taught us. We will also see how astronomers of today contribute to our everyday lives. Some say that our first astronomer was a great astronomer. Other say, “Ptolemy was the only great astronomer of Roman Alexandria.” (Brown, 2016) It’s all a matter of opinion, but what we cannot deny was Ptolemy was a great astronomer of his time and today. We do not know much about Ptolemy’s personal life. What we do know about him came from his work. He was born around 85ce in Egypt to a Greek family even though he bore a roman name. To say Ptolemy was diverse is an understatement. He was also diverse in his studies...

Reionization

...Cosmic Reionization Ultra-deep imaging with the Hubble Space Telescope has now uncovered galaxies within the first billion years of cosmic history. These galaxies represent some of the first objects ever formed, yet in terms of early galaxy formation they are only the tip of the iceberg. Most of the galaxies at this early epoch are too faint to study directly, even with Hubble. Galaxies, moreover, represent only a small fraction of all the matter in the Universe. Most of the matter instead resides in a vast network of dark matter and baryons known as the intergalactic medium (IGM). One of the primary aims of extragalactic astronomy is therefore to understand how galaxies form out of this network, and how galaxies, in turn, affect their environments. Of particular interest is how some of the very first galaxies took shape, and how they changed the properties of the large-scale IGM. One of the key features of the IGM in the present day Universe is that the gas is highly ionized. This would not always have been the case, however. After the Big Bang, the gas would have cooled and become neutral as the Universe expanded. Only after the first luminous sources appeared and began to emit ionizing photons would hydrogen in the IGM have been re-ionized. We believe that this process occurred within the first billion years, and represents one of the most dramatic impacts that early galaxies had on the properties of the baryons in deep space. In addition to direct searches for distant...
