How Beautifully Our System Works

Antennae galaxies, an intense star-forming region created when two galaxies began to collide some 200 million to 300 million years ago. The bright, blue-white areas show newly formed stars surrounded by clouds of hydrogen, which are colored pink. A similar collision is expected between our galaxy, the Milky Way, and the nearby Andromeda galaxy in several billion years.

The Boomerang Nebula (Bow-tie Nebula)

The Boomerang Nebula is about 5000 light years away  from the Earth, situated in the constellation Centaurus and is the coldest place known in the entire universe at a temperature of  1K. According to the astronomers, the nebula houses a central dying star which has been losing one-thousandth of  a solar mass of material from the last 1500 years. The bow-tie shape of the nebula is said to have formed due to very fierce winds (blowing at about 500,000 kmph) blowing the ultra cold gas away from the dying star.

The Wow! signal. 

A signal sequence that lasted for 72 seconds in 1977 but has never been seen again. The signal appeared to come from a globular cluster in the Sagittarius constellation, but to this day no definite answer for where the signal originated can be given.

Hoag’s Object Hoag’s Object is a non typical galaxy of a type known as a ring galaxy. It is a nearly perfect ring of hot blue stars which circle around the yellow nucleus of this ring galaxy. The galaxy is approximately 600 million light years away from the constellation Serpens. Image credit: NASA
