For the first time ever, astronomers have witnessed the birth of one of Neptune’s enormous “Great Dark Spot” storms. It is measured to be 8,000 miles by 4,100 miles (13,000 kilometers by 6,600 kilometers). Astronomers were studying Hubble Space Telescope images of a relatively small Neptune maelstrom that formed in 2015 when they noticed bright … Read more How Big is the Spot on Neptune
Our galaxy, the Milky Way, is home to over 400 billion stars of varying brightness. The majority of these stars are described as being main sequence, which means their cores are fusing hydrogen to create helium. The Sun is a main sequence star and its chemical composition mainly consists of hydrogen and helium with trace … Read more What are the Basic Composition of All Stars?

The Pleiades, also known as the Seven Sisters and Messier 45, are an open star cluster containing middle-aged, hot B-type stars in the north-west of the constellation Taurus. It is among the star clusters nearest Earth and is the cluster most obvious to the naked eye in the night sky. Computer simulations have shown that the Pleiades were probably formed from a compact configuration that resembled the Orion Nebula. Astronomers … Read more How to Spot the Pleiades Star Cluster
