A supernova was observed in constellation known as Cassiopeia. Tycho Brahe, Danish astronomer, discovered a nova in the constellation of Cassiopeia. It is described in detail in his book "De Nova Stella" (1573). The light eventually became as bright as Venus and could be seen for two weeks in broad daylight. After 16 months, it disappeared.

It was reported that scientists have observed the biggest supernova - stellar explosion - ever detected, the violent death of a huge star up to 100 times more massive than our sun in a faraway galaxy. Scientists said the supernova, releasing twice as much energy as any other stellar explosion observed to date, occurred about 4.6 billion light years from Earth in a relatively small galaxy.

It was reported that scientists for the first time have spotted a moon-forming region around a planet 370 light years from Earth. The Jupiter-like world, orbiting a young star called PDS 70, is surrounded by a disk of gas and dust massive enough that it could spawn three moons the size of the one orbiting Earth.

Astronomers confirmed that an object they thought was a distant galaxy is actually the brightest extra-galactic pulsar ever seen. The new pulsar, called PSR J0523-7125, is about 50,000 parsecs from Earth, in the Large Magellanic Cloud (LMC). The pulsar is ten times brighter than any other pulsar found outside the Milky Way.
