 A Boeing-built Intelsat communications satellite launched three years ago is drifting in geostationary orbit after suffering a fuel leak and releasing debris fragments last week, according to an analysis by space surveillance experts. Ground-based telescopes operated by ExoAnalytic Solutions, a commercial company that tracks objects in space with a network of [...]

A brief and rapidly fading blip of light from a distant galaxy has given astronomers a glimpse into a never-before-seen event: The birth of a binary neutron star system. Oh yeah, stuff like this makes my brain tingle. There's a lot of fun things here. The galaxy is called IV Zw 155 [...]

Have you ever seen an aurora? I haven't. Well, not really; twice in my life I've seen a dull glow on the northern horizon, but seeing a full-blown shimmering curtain of light sweeping down from the heavens is still something that's — hopefully — still in my future. Part of the problem [...]

An embarrassing problem that's come up in recent years is a weird one: naming astronomical objects. It used to be easy! There were just a handful of planets, a couple of dozen moons, and some asteroids (comets are named after their discoverers, so no prob there). But then astronomers decided to [...]

For the first time in human history, astronomers have combined the power of telescopes from across our planet to create an image that shows the event horizon of a black hole. The collected array is called the Event Horizon Telescope, and over the course of four nights in April 2017, it [...]

Globular clusters just keep coming up in my writing lately. In my defense, they're really interesting objects. Dozens of light years across, they can contain hundreds of thousands of stars all held together by their mutual gravity, circling their center of gravity on orbits like bees around a hive. Many [...]

If you haven't noticed, our planet is beautiful. Sure, we have oceans, clouds, forests, mountains, lakes, deserts, polar ice caps, and and and. That's obvious. But when you see the Earth from space, well, its beauty is so compelling that were I to see it myself I have no doubt I'd [...]

One thing I like to mention when I talk about asteroid impacts is that if you wait long enough and do nothing, they're gonna happen. To illustrate that I point to the Moon. With no atmosphere to stop even the smallest bits of interplanetary debris, and no active weather system to [...]
