When stars explode, a cocoon of gas usually develops in their immediate surroundings. Now, a study conducted using the NASA Chandra X-Ray Observatory provides the first direct evidences of a supernova shock wave breaking through this gaseous envelope.
The investigations team analyzed X-ray signals that Chandra dete... |

Investigators studying the supernova remnant Cassiopeia A say that an analysis of the distribution of chemical elements within the structure suggests that the massive precursor star that spawned the remnant was turned inside out by the huge blast.
To reach this conclusion, researchers first had to map the distributi... |

This image shows what the largest star in the Eta Carinae binary system might look like when it blows up, in the near (astronomical) future. This may translate into a few million years from now, but that is a very brief time in universal terms.The largest star in the system has already experienced a massive explosion... |

Astronomers analyzing a supernova remnant in the Small Magellanic Cloud – one of the dwarf galaxies orbiting the Milky Way – recently discovered that the giant cloud was inhabited by a very young pulsar.
A pulsar is a type of neutron star, whose position in the sky relative to Earth makes its radiation j... |

Pandigital finally made the official introduction of the SuperNova, a mobile electronic that, depending on who you ask, is either an e-reader or a tablet.
The one thing that works as a turnoff for many on the tablet front is that this sector is one of many models but few successes.
Basically, many tablets wer... |

The international astronomical community is currently scrambling to analyze an impressive new supernova, that was observed taking place in the nearby galaxy Messier 51, also known as the Whirlpool Galaxy. The cosmic structure is located in one of the 88 official modern constellations, called Canes Venatici. In the ni... |

Astronomers were recently able to identify what they consider to be the most likely formation mechanism for dramatic cosmic events known as Type Ia supernovae. The finding goes a long way towards clearing the mystery associated with these objects. Past studies had suggested that these events occur when a white dwarf ... |

Nearly 50 years ago, a stellar explosion captured by telescopes posed a serious dilemma to astronomers trying to determine what type of cosmic event this was. Even now, so many years after the star disappeared, experts cannot agree on what it was. Two main camps were formed to explain the cosmic event, with one of th... |

A group of investigators believes it may have stumbled upon the most massive neutron stars ever discovered. The new body is about twice as heavy as the Sun, a fact that lends additional credence to theories saying that they are made up mostly of neutrons. Some theories have stated that the bodies could also be made o... |

A group of astronomers believes it may have discovered a new and interesting cosmic event, in which massive stars go supernova not in a massive bang, but rather by fizzling out inside a dust cocoon. The cosmic dust is apparently capable of smothering the star to death, investigators believe, adding that this type of ... |

Supernova explosions are generally accepted to be among the most violent phenomena taking place in the Universe. They take place when massive stars reach the end of their burning cycle, and exhaust their hydrogen supply. As they explode, they produce so much energy that their light signature briefly outshines that of... |

In a recent discovery, experts have found a distant stellar explosion that did not behave in the manner expected from such a cosmic event. Namely, the supernova had some of the traits similar to a powerful gamma-ray burst (GRB), but was not exactly either of the two phenomena. Astrophysicists believe that future stud... |

Stellar dust can be found in nearly every portion of a galaxy, and its role is one of the most important in the Universe – more specifically that of facilitating the formation of stars and planets, implicitly.

In November 1572, Danish astronomer Tycho Brahe saw (or thought he saw) a brand new star in the Cassiopeia constellation, without even using a telescope. In fact, it was a supernova, the violent death of a star, and it was shining so bright that it was visible in broad daylight and even outshone Venus at some point. ... |
