What is a Supernova? To say in three words, a supernova is an exploding star. Okay, that was more than three, but you get the point. A supernova is more significant than a nova, but less so than a hypernova. Supernovae are very bright and generate bursts of radiation that can briefly outshine a whole […]
Each star has its own movement. This is the simplest way to describe a heliacal rising. Heliacal rising is a phenomenon by which a star becomes visible after being behind the Sun for a certain period of time. Just before sunrise, on the event of a heliacal rising, the star will shine above the eastern

The region in the Solar System which is now called the Kuiper belt had been hypothesized variedly for decades but it was only in 1992 that direct evidence of its existence was found for the first time.
It is approximated that a supernova (plural: supernovae) occur in the Milky Way Galaxy once every 50 years. It is a stellar explosion, or the destruction of a star at the end of its life period. The materials that were wiped out from the explosion are called ejecta (Ejecta is also used to refer to
