Stars die all the time, but the untimely passing of SN 1572, also known as Tycho's Supernova, is possibly the most famous. That's because it's relatively close to us in the Milky Way's Cassiopeia constellation, so when it exploded in the year 1572, i...
A star died violently and left behind this ‘fluffy’ ball
Stars die all the time, but the untimely passing of SN 1572, also known as Tycho's Supernova, is possibly the most famous. That's because it's relatively close to us in the Milky Way's Cassiopeia constellation, so when it exploded in the year 1572, i...
At 11,000 light-years away, it's safe to say you won't be able to visit Cassiopeia A even if private space corporations start selling seats to amateur spacefarers. Thanks to a team of scientists, though, you might be able to see the 300-year-old supe...
A couple of weeks ago, the LIGO (Laser Interferometer Gravitational-Wave Observatory) and Virgo teams announced the detection of another set of gravitational waves -- the fourth since LIGO's first detection in September of 2015. The observations of t...
Suddenly, even the Large Hadron Collider seems downright quaint. Researchers have found a combination of cosmic phenomena that's creating the universe's largest known particle accelerator. At least one supermassive black hole in a galaxy cluster ha...
Believe it or not, that's not a star field you're looking at. Researchers have used NASA's Chandra X-ray Observatory to produce an X-ray image of space (the deepest-ever X-ray, in fact) that has uncovered an abundance of supermassive black holes --...
Back in 1572, a white dwarf's explosion shone brightly on the sky. It was visible to the naked eye, and astronomers like Tycho Brahe were able to monitor the event despite not having the equipment we do today. We might have missed the chance to see w...
It's no secret that auroras are a common presence on other planets... however, you might be surprised by the ones you can't usually see. A new study using NASA's Chandra X-ray Observatory has caught solar storms creating X-ray auroras on Jupiter as...
