Just what the heck are fast radio bursts? Let me be clear right off the bat: No one knows. But we just got a step closer to understanding them, which infuriatingly, also means things are even more complicated than they were before. Fast radio bursts, or FRBs, are one of the more [...]

I recently wrote about NGC 6240, a collision between two galaxies where it looks like there were not two but three supermassive black holes seen in the observations. One of the two colliding galaxies had two bright spots in its core, which the astronomers interpreted as being two supermassive black [...]

Right now, you are adhered to the surface of a ball of iron, rock, and water, thousands of kilometers wide, spinning on an axis and, along with many other balls of various sizes and compositions and rotation periods, circling around a much larger ball of fiercely hot plasma that is [...]

When you think of asteroids, you probably think of them occupying the vast area of the solar system between the orbits of Mars and Jupiter. There's a reason we call it the Main Belt, after all. But asteroids can be pretty much anywhere in the solar system (theoretically, at least). There's [...]

We live in the Milky Way galaxy, considered to be a pretty beefy example of its kind. It's a spiral galaxy, with over 200 billion stars, stretching about 150,000 (and perhaps up to 200,000) light years across its diameter. But there are bigger galaxies out there. Malin 1, for example, looks [...]

For a couple of decades, astronomers have had something of a thorny problem: How did supermassive black holes get so supermassive? We see these monster black holes in the centers of pretty much every big galaxy, some with millions or even billions of times the mass of the Sun. By studying [...]

Is Venus geologically active right now? Are volcanoes erupting on its surface even as you read this? Maaaaaybe. The evidence has been growing for years now, but a new piece of research just published makes a compelling case that Venusian volcanoes have been belching out fresh lava in just the past [...]
