Space is such a beautiful yet mysterious place. There are so many things to discover in space. With the latest images from the Hubble and now the James Webb Space Telescope we get a better understanding of the objects in space. Im this video we take a look at something called the Hoag's object or a ring shaped galaxy. Stay tuned

Galaxies are some of the most massive objects in the universe. There are different varieties of galaxies in the vastness of space. These various categories or types of galaxies make it easy for astronomers to classify them and conduct deeper research. Almost all galaxies in our universe are spiral , elliptical or irregular in shape. However, a few odd balls fit into none of these categories and one galaxy stands alone.
If you look closely at the Serpent constellation also called the Serpent Caput, you'll find an unusual ring galaxy. It is named after Arthur Hoag, who discovered it in 1950 and identified it as either a planetary nebula or a peculiar galaxy. The galaxy has approximately eight billion stars, and is roughly 100,000 light years across.
A nearly perfect ring of young hot blue stars circles the older yellow nucleus of this ring galaxy approximately 600 million light-years away in the constellation Serpens. The diameter of the 6 arcsecond inner core of the galaxy is about 17 kilo light years while the surrounding ring has an inner 28″ diameter of 75 kilo light years and an outer 45″ diameter of 121 kilo light years. The galaxy is also estimated to have a mass of 700 billion suns. By comparison, the Milky Way galaxy has an estimated diameter of 150-200 kilo light years and consists of between 100 and 500 billion stars and a mass between 800 billion and 1.54 trillion suns.
Many of the galaxy's details remain mysterious, foremost of which is how it formed. So-called "classic" ring galaxies are generally formed by the collision of a small galaxy with a larger disk-shaped galaxy, producing a density wave in the disk that leads to a characteristic ring-like appearance. Such an event would have happened at least 2–3 billion years ago, and may have resembled the processes that form polar-ring galaxies. However, there is no sign of any second galaxy that would have acted as the "bullet", and the likely older core of Hoag's Object has a very low velocity relative to the ring, making the typical formation hypothesis quite unlikely.[l Observations with one of the most sensitive telescopes have also failed to uncover any faint galaxy fragments that should be observable in a collision scenario. However, a team of scientists that analyzes the galaxy admits that "if the carnage happened more than 3 billion years ago, there might not be any detritus left to see."
