Astronomers have found the first circumstantial evidence for a supernova triggered by a merger with a neutron star or maybe even a black hole. The post New Kind of Supernova Implodes Stars Before Their Time appeared first on Sky & Telescope. [...]

In November 2021, NASA is launching a bold mission to test the technology needed in case we ever have to push a potentially hazardous asteroid off of an Earth-impacting trajectory. Called DART — for Double Asteroid Redirection Test — the 500-kilogram spacecraft will slam into an asteroid’s moon at over [...]

From the ground, the Earth looks flat. That’s an illusion of sorts, of course. There’s a lot of evidence the Earth is actually a spheroid if you look carefully. And, obviously, from space our planet is clearly a ball. This illusion can work in reverse, too. Some disk-shaped galaxies are face-on to [...]

One of my favorite space rocks is 216 Kleopatra. It’s an asteroid in the main belt between Mars and Jupiter, and it’s one of the biggest ones. The reason I love it is because of its shape: It looks like a cartoon dog bone or a dumbbell, two elongated lobes stuck [...]

Astronomers reached a 1.6 kilometerstone* recently: They observed the 1,000th near-Earth asteroid via radar. That’s a lot of rocks. But it’s only a fraction of what’s out there. Near-Earth asteroids (or NEAs) are pretty much as advertised: Asteroids that get near Earth. Specifically they’re defined as any asteroid with an orbit that [...]

What happens when a massive star eats a black hole or neutron star? Theoretical models show it explodes, epically, but only after a series of events that cause the star to eruptively eject its outer layers before the compact object plunges into the star's core, disrupts it, and creates one of [...]

Before the end of year, two different groups from two different countries expect to launch extremely unusual but similar experiments into space. These experiments — and I can't believe I'm writing this — will test to see how well wood works as a structural component for satellites. Yes, wood. Like, from [...]

Astronomy rocks! Well, planetary science rocks. Literally. Let’s explore two small worlds, each similar yet wildly different to the other, but both with a bolder tale to tell. Or a boulder one. We’ll start with Ceres, the largest object in the main asteroid belt between Mars and Jupiter, and so big it was [...]
