Recent observations conducted using the NASA Chandra X-ray Space Telescope revealed that energetic radiations emanating from Jupiter's northern hemisphere are in fact originating in a single hot spot. In other words, they are not produced over a larger surface area, as originally thought. What's more, the ... |

A team of investigators reports the discovery of the fastest-moving winds ever found to be released by a stellar-mass black hole. Unlike their supermassive companions, these dark behemoths are relatively small, tipping the scales at only a few times the mass of the Sun.
However, they do release radiations and winds... |

In an article I wrote yesterday about the supermassive black hole at the core of the Milky Way, I presented a theory suggesting that the X-ray flares produced by Sagittarius A* are caused by asteroids falling through the event horizon. Here are more details of that study. Now, the image in this post is a rendition t... |

Using data from a number of telescopes, experts were recently able to snap a new view of the galaxy cluster Abell 2052. The formation is of interest because the massive gas clouds it contains display a sloshing-like motion, similar to how a liquid wobbles inside a glass when moved.
Investigators used visible-light ... |

When a massive star reaches the end of its burning cycle, it becomes unable to sustain nuclear fusion all on its own, and also exhausts all of its hydrogen fuel. When this happens, the object sheds the outer layers of its atmosphere, all the way to the core, in a violent explosion called a supernova. Classifying the ... |
