Astronomers have spotted the brightest and most energetic supernova ever recorded. The event, known as SN2016aps, may have been the result of two stars merging and then exploding.
Scientists using the Hubble Space Telescope have detected quasars sending outbursts of energy roaring through their galaxies, according to new research.
Follow the story of golden atoms from their birth in stellar explosions via incorporation into formation of our planet to their coming together in a golden nugget and appearance in the Earth's crust.
The biggest explosion seen in the universe has been found. This record-breaking, gargantuan eruption came from a black hole in a distant galaxy cluster hundreds of millions of light years away.
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.
Supernovae happen all the time, but this one was different. "Cow," as astronomers are calling it, was a massively bright explosion 200 million light years away.
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.
One of the most puzzling cosmic blasts yet observed has been observed by NASA
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.
