From asteroids capable of destroying entire species to supernovae that could exterminate life on Earth, outer space has no shortage of forces that could wreak havoc on our planet. But there’s something in space that is even more terrifying than any of these — something that wipes out everything it comes near. Continue reading
Fascinate your students with this large scale re-enactment of Isaac Newton’s classic thought experiment.
This video is about the astronomical amount of astronomical evidence for black holes, ranging from x-ray binaries with accretion disks, supermassive infrared-radiating galactic nuclei black holes, orbital characteristics of high mass binaries, and direct gravitational wave detection of inspiraling merging black hole binaries with LIGO. Yes, they’re real. Continue reading
Can throwing a penny off of the top of the Empire State Building lead to a murder charge, and what is surprisingly more deadly? Continue reading
The merging of two neutron stars was detected by gravitational waves and then by telescopes in all parts of the electromagnetic spectrum. This is a historic detection as it demonstrates: Continue reading
It’s going to be a lot easier to colonize Mars if we can terraform it first. The first step would be to give Mars a thicker atmosphere, which means it will need a magnetic field, or magnetosphere, to protect it. Here’s how we would do that. Continue reading
The collision of two neutron stars, seen in an artist’s rendering, created both gravitational waves and gamma rays. Researchers used those signals to locate the event with optical telescopes. For the first time, scientists have caught two neutron stars in the act of colliding, revealing that these strange smashups are the source of heavy elements such as gold and platinum. Continue reading
