After a star explodes, the resulting supernova remnant collapses in on itself and could begin the cycle again, creating generations of stars enriched with heavy elements

A nearby star that exploded some 3 million years ago could have removed all dust smaller than a millimetre from the outer solar system

A strange supernova remnant first appeared as a “guest star” seen in 1181 by sky watchers in China and Japan

Scientists have finally found the compact object at the heart of the famous supernova of 1987, and it’s not a black hole

Threat type: Trojan

Aliases: MSIL/Agent.5676!tr (FORTINET)

Platforms: Windows

Overall Risk Rating: Low

Damage Potential: High

Distribution Potential: Low

Reported Infection: Low

Information Exposure: Low

Overview:

This Trojan arrives on a system as a file dropped by other malware or as a file downloaded unknowingly by users when visiting malicious sites. It may be hosted on a website and run when a user accesses the said website.

It executes commands from a remote malicious user, effectively compromising the affected system.

For the first time, astronomers have found a supernova explosion with properties similar to a gamma-ray burst, but without seeing any gamma rays from it.

In 1987, light from an exploding star in a neighboring galaxy, the Large Magellanic Cloud, reached Earth. Named Supernova 1987A, it was the closest supernova explosion witnessed in almost 400 years, allowing astronomers to study it in unprecedented detail as it evolves.

A new X-ray study of the remains of an exploded star indicates that the supernova that disrupted the massive star may have turned it inside out in the process.

Two very different models explain the possible origin of Type Ia supernovae, and different studies support each model. New evidence shows that both models are correct - some of these supernovae are created one way and some the other.

1800s, astronomers surveying the night sky in the Southern Hemisphere noticed something strange: Over the course of a few years, a previously inconspicuous star named Eta Carinae grew brighter and brighter, eventually outshining all other stars except Sirius, before fading again over the next decade, becoming too dim to be seen with the naked eye.
