Recent findings suggest that relatively close supernovas could theoretically have triggered at least four disruptions to Earth's climate over the last 40,000 years. What happens in space may not always stay in space.
Astronomers have found two objects that, added to a strange object discovered in 2018, constitute a new class of cosmic explosions. They share some characteristics with supernova explosions and gamma-ray bursts.
Scientists using the Hubble Space Telescope have detected quasars sending outbursts of energy roaring through their galaxies, according to new research.
This star is going to go nova (not supernova) by 2083. V Sagittae is in the constellation Sagitta and is s about 1100 light years from Earth. When the brightening happen, it will be historic. V Sge will appear startlingly bright in the night sky.
A titanic, expanding beam of energy sprang from close to the supermassive black hole in the center of the Milky Way just 3.5 million years ago, sending a cone-shaped burst of radiation through both poles of the galaxy and out into deep space.
With globe-spanning collaboration that enables to alert various telescopes to train their sights on the event, we are getting closer and closer to understanding how massive stars end their life and what leads up to the final explosion.
A mysterious flash of X-rays has been discovered by NASA’s Chandra X-ray Observatory in the deepest X-ray image ever obtained. This source likely comes from some sort of destructive event, but may be of a variety that scientists have never seen before.
In 2009 astronomers detected an unusual object, named CX330, as a source of X-rays as it was surveying the center of the Milky Way galaxy but they had not idea what it was. Today, astronomers have a better idea to what this strange object is.
Astronomers have discovered a new cosmic explosion: a gamma-ray burst and its associated supernova. Gamma-ray bursts (GRBs) are the most powerful blasts in the Universe, and are thought to be created in the deaths of the most massive stars.
