APOD 1.8

Located closed to the constellation of Scorpius, Messier 6 and Comet Siding Sprint are about 2,000 light-years away. It has been concluded that the comet will be passing by the planet Mars with only 139,500 kilometers of distance. The comet will be observed by a spacecraft in Mars's orbit. Can you believe it will be the first comet that will be studied by spacecraft? Stay tune on the information the spacecraft will fine.

Johann Bayer

The astronomer Johann Bayer was born in 1572 on Rhain, Germany.  He went to the University of Ingolstadt where he studied philosophy and law. Like many, Bayer was interested in the new discoveries in astronomy. He did many investigations and published several books but his most famous work was the book called Uranometria. Later on in his life, Bayer was appointed as legal advisor in the city council of Augsburg. He became a successful and wealthy name due to his position. Also, he was recognized for the work that he had done in astronomy.

What people remember about Johann Bayer the most is his book, Uranometria.  The book consists of 48 constellations, which Ptolemy had discovered, and the naming of stars in the constellations. Bayer’s information about the sky was more modernized and updated compared to the previous astronomers’ information. For example, around the time Bayer wrote the book the Dutch navigator Pierter Dirckszoon Keyser defined 12 new southern constellations. Therefore, Bayer added this information in his book.  

Although Bayer may deserve the credit for updating astronomical information, his celestial atlas formed issues. To begin with, all of the constellations in his book were labeled left to right. This caused a problem because previous astronomers had done the atlases right to left, which formed confusion to many. He also bracketed stars that have the same magnitude in each constellation but, unfortunately, did not show how he assigned the letter included in each bracket. This issue made it harder for his readers to understand what he was presenting in his book. Bayer did demonstrate new information to the astronomical world but he could have improved the way he presented it to avoid confusion in later work about stars.

Bayer has also contributed to the discoveries of astronomy by demonstrating different names for the constellations from the Bible. He was a strong Protestant, therefore, finding names for constellations from the Bible seemed like the best alternative for him. He named the constellations from the Northern Hemisphere from the New Testament and the Southern Hemisphere constellations from the Old Testament. As interesting as that sounds, Bayer’s opinion about the naming of constellations was ignored.

Throughout his time, Johann Bayer was an important astronomer. He gathered all the constellations and their position and added them in his book Uranometria. Yes, the information in his book might have been confusing but at the time he wrote it, it was just what the people needed to become information about the constellations in the sky.

APOD 1.7

The connection between the Sun and the Moon is the Milky Way Galaxy. The colors across the sky is our dear galaxy, the Milky Way. In this picture, there are two sandstone monoliths, located in Utah, each representing the Temple of the Sun and the Temple of the Moon. The perks about this picture is that it shows you where stars, nebulas, and the Andromeda Galaxy are located. It is amazing what one can find in the middle of the dessert!

APOD 1.6

The Butterfly Nebula from Hubble is the name. This Nebula has a temperature of around 250,000 degrees C! It truly is quite a hottie. This pictures does not come close to demonstrating the majestic colors this nebula has. If you wish to see this nebula with a telescope try to look towards the constellation of Scorpius. You will be amazed!
