But how young these cosmic youngsters really are? Although her exact age remains uncertain,

A new theory on how to grow giant stars

Scientists have put forward a new theory of how can grow giant stars.

According to scientists, the young stars can grow to unusually large sizes, exceeding the size and mass of our sun 10 times. Such a huge and massive size of these stars can afford in the event that they are surrounded by a cocoon of old stars.

LRO observes mercury and hydrogen explosion in the spectrum probes GRAIL

When NASA's twin probes GRAIL mission scientists were deliberately destroyed, sent spacecraft into collision with the lunar surface in December, complex scientific instruments Orbiter Lunar Reconnaissance Orbiter (LRO) were in a good position to monitor the effects of this collision. In escaped after the explosion of a gas jet tool Lyman Alpha Mapping Project (LAMP), 

Astronomers have discovered a new type of supernova

Previously it was thought that supernova typically have one of two main scenarios. But a team of astronomers, including Wendy Friedman, Mark Phillips and Eric Persson of Carnegie, reported the discovery of a new type of supernova, called type 1ah.

Astronomers used to divide supernova into two main categories: type 1a supernova and supernova occurring core-collapse. Supernova, accompanied by collapse of the core,
