On 21 May 2019, from a distance of 7 billion light-years away, our gravitational wave detectors were rocked by the most massive collision yet. From analysis of the signal, astronomers concluded that the detection was the result of two black holes smashing together, weighing in at 66 and 85 times the mass of the Sun respectively.
SpaceX launched a prototype Starship rocket Tuesday from its Boca Chica, Texas, flight facility, successfully sending the silver booster up to an altitude of about six miles as planned. But the unpiloted test flight ended with a spectacular explosion when the rocket failed to right itself and slow down enough for a tail-first landing.
Astronomers are looking for the bones of dead planets inside the corpses of dead stars — and they may have just found some.
This weird elongated rock shard could have been displaced by a meteor impact.
Earth’s second moon will make a close approach to the planet next week before drifting off into space, never to be seen again.
As countries begin an age of Martian exploration, planetary protection advocates insist we must be careful of interplanetary contamination
Who has an even bigger grin than ten years ago? This goofy-looking crater on Mars.
The Kavli Institute for the Physics and Mathematics of the Universe (Kavli IPMU) is home to many interdisciplinary projects which benefit from the synergy of a wide range of expertise available at the institute. One such project is the study of black holes that could have formed in the early universe, before stars and galaxies were born.
Almost a millennium ago, a major upheaval occurred in Earth’s atmosphere: a giant cloud of sulphur-rich particles flowed throughout the stratosphere, turning skies dark for months or even years, before ultimately falling down to Earth.
