America’s war in Southeast Asia is fading fast from memory. These maps offer a horrific reminder.
The Solar System isn't a vortex, but rather the sum of all our great cosmic motions. Here's how we move through space.
The past ~4 billion years have been an incredibly successful, unbroken run for life on Earth. The future won't be nearly so bright.
If everything eventually dies and decays, is there a way to prolong the inevitable? Our Universe, as it exists today, puts us in an incredibly privileged position. Had we come […]
Media provocateurs and conspiracy theorists insist that they're "just asking questions." No, they aren’t.
Just 12 million light-years away, the galaxies Messier 81 and 82 offer a nearby preview of the Milky Way-Andromeda merger.
What we’ve seen isn’t necessarily what we get, but the most common world doesn’t look like ours. There’s a very common myth out there in astronomy: the idea that the Sun […]
It comes from a supernova seen just 33 years ago, and it doesn’t pulse. 33 years ago, a supernova occurred just 168,000 light-years from Earth. This new image of the supernova […]
If dark matter exists in a large halo in our galaxy, made up of particles, then it's passing through us constantly. But how much?
Named M51-ULS-1b, it's certainly a curious astronomical event. But the evidence is far too weak to conclude "planet."
