The concept was likened to a porch light in our little neighborhood of the galaxy.

The story of John Couch Adams, “the man who failed to discover Neptune,” and his cosmic redemption. Perhaps its human nature to want to only think positive thoughts about our […]
Forget the spectacular explosions we create here on Earth. The Universe outdoes us in every way imaginable. Forget mere chemical reactions; in space, matter-energy conversion creates unprecedentedly powerful explosive events. […]
We know that it’s ‘the red planet’ because of the iron in its soil. But why, with such a thin, carbon dioxide atmosphere, is the martian sky so red and bright? […]
No matter what Martin Rees or anyone else says, physics dictates that the world is safe. The Large Hadron Collider is the world’s most powerful particle accelerator. An aerial view of […]
In order to build a second Earth, we need to look at how the first one was made.
We’re putting the “care” back into “healthcare.”
Once again, our circadian rhythm points the way.
A Japanese astronomer shows that the Milky Way galaxy was formed in two stages, “dying” in between.
The Perseid meteor shower during this weekend’s new moon should be fabulous.
A massive black hole at the center of the Milky Way and a single star did it.
The solar neighborhood is so different than people imagine. But for the first time, we know what it’s like. When you look up at the stars in the night sky, they […]
Ancient beverages such as tea and chamomile can heighten your modern-day performance.
Different measurements of the Universe’s rate of expansion give inconsistent results. But this simple solution could fix everything. In 1915, Einstein’s theory of General Relativity gave us a brand new […]
It’s the first, most naive question you might think to ask. The solution is a lot more complicated than you imagine. According to a large amount of evidence, the overwhelming majority […]
We’ve put so much together about the Universe. Could it all come tumbling down? We’re always on the lookout for the next big thing, and even our best guesswork is often […]
Despite being 28 years old and having a gyroscope failure, Hubble still delivered these 10 amazing snapshots in 2018. Year after year since its 1990 launch, Hubble keeps revolutionizing our view […]
Wind power on Mars makes it possible for any rover or other craft to collect power at the poles or other areas on the planet that don’t get constant sunlight.
We aren’t lunarly exclusive. Earth has a few minimoons whizzing around us, including one that comes back into our orbit every 20 years or so.
Every physical theory has constants in it. The gravitational constant is remarkably uncertain. When we first began formulating physical laws, we did so empirically: through experiments. Drop a ball off […]
A climate catastrophe 2 billion years ago almost ended life on Earth. Here’s the biggest lesson of all. Although it was more than 4½ billion years ago that planet Earth formed, […]
Climate change stands to take the one thing away from us that might make it easier to deal with, cheap beer.
Binary stars and common envelope evolution illustrate messy but “tasty” science.
The Universe was born matter-antimatter symmetric. Here’s what happened when the last of our antimatter disappeared. Things happen fast in the earliest stages of the Universe. In the first 25 […]
The Mars landing is a reminder that we never know what—or whom—we might discover out there.
Both effects could be responsible for a redshift. But only one makes sense for our Universe. In physics, like in life, there are often multiple solutions to a problem that […]
Astronaut Buzz Aldrin captured the first selfie in space, and he doesn’t want kids these days to forget it.
The Nazis actively searched for Atlantis, seeing it as important to their mythology.
Talking about climate change doesn’t have to be an argument over Thanksgiving dinner. Some people, though maybe not all, can be persuaded.
