☆ NASA explains how it would alert the public of an apocalyptic asteroid strike
  + stars: | 2024-02-17 | by ( Ellyn Lapointe | ) www.businessinsider.com   time to read: +6 min
In the event of an impending hazardous asteroid strike, NASA already has its plan in place to alert the public. NASA’s Planetary Defense Coordination Office is tasked with finding, tracking, and assessing the risk associated with potentially hazardous asteroids in our solar system. To do that, NASA works with a global coalition of astronomers called the International Asteroid Warning Network (IAWN). There are about 2,300 known potentially hazardous asteroids out there, and roughly 153 of them are larger than 0.6 miles across. If Bennu does head toward Earth, NASA has a few tricks up its sleeve to defend our planet.

☆ Black holes are rampaging through our universe at more than 2.2 million mph and scientists think they now know why
  + stars: | 2024-01-27 | by ( Maiya Focht | ) www.businessinsider.com   time to read: +6 min
These black holes get kicked into space, moving as fast as 1,000 kilometers per second. AdvertisementScientists studying how supernovas explode may have discovered a new process for how certain black holes form. Turns out, some baby black holes hit the ground running at colossal speeds just moments after they take shape. Asymmetrical explosions can lead to powerful kicks that send black holes shooting into space at over 2 million mph. AdvertisementIf the black holes are movingIf you hear blazing-fast black holes and start to panic, don't.

☆ NASA scientists think some planets are shrinking because powerful radiation from their cores is pushing away their atmospheres
  + stars: | 2023-11-17 | by ( Sebastian Cahill | Morgan Mcfall-Johnsen | ) www.businessinsider.com   time to read: +4 min
Planets beyond our solar system have a size gap, where worlds seem to shrink past a certain range. Scientists think this is because some sub-Neptunes shrink — losing their atmospheres and speeding through the size gap until they are as small as a super-Earth. AdvertisementThe planets themselves may be pushing their atmospheres awayShrinking exoplanets may lack the mass (and therefore the gravity) to hold their atmospheres close. AdvertisementThe other hypothesis, called photoevaporation, says that a planet's atmosphere is dissipated by the radiation of its host star. AdvertisementThe scientists found that most of the planets there retained their atmosphere, making the core-powered mass loss a more likely cause of eventual atmosphere loss.
