We all wish we could find an Earth 2.0 – a planet about the size of our own, made of roughly the same chemical mixture, orbiting a sun-like star at just the right distance so that all its water doesn’t evaporate or freeze.
Small stars can pack a surprisingly powerful punch. For an example look no further than the nearest neighbor to our solar system, Proxima Centauri. This little red dwarf just sent off a blast a hundred times more powerful than anything that our own sun ever has.
Our Milky Way galaxy is on a collision course. With destiny. With destruction. With fate. With our nearest neighbor, Andromeda. You can stream HOW THE UNIVERSE WORKS on discovery+.
Want to see what’s behind a black hole? Easy. You just…stare at it. The whole thing is pretty weird to contemplate, but an excellent example of the space-bending (and mind-bending) powers of black holes.
Sure, the sun looks all calm up there in the sky. Kids even put little smiley faces on the sun when they draw it. But look closer and you’ll find that our sun has a nasty, violent temper.
What’s shiny and lives under the Martian ice? No, it’s not a joke. It’s clay. Just…clay.
The Milky Way is a giant, sprawling, beautiful spiral galaxy. It's also your home. Let's take a little tour.
NASA’s Juno probe, the supremely awesome Jupiter orbiter, recently captured some stunning images of Ganymede, the largest moon of Jupiter, during the orbiter’s 34th trip around the giant.
Meet the humble Ophiuchus galaxy cluster. It’s just another dense clump of galaxies, one of approximately a bajillion, dotting the universe. It sits about 240 million lightyears away from Earth.And its heart is missing.
In a bowl, combine a tablespoon of hydrogen and a teaspoon of helium to a cup of dark matter. Add a pinch of neutrinos and sprinkling of radiation. Mix well to combine. Heat to several million Kelvin. When mixture has risen, leave to cool for 13 billion years.
Recently NASA announced two brand-spanking new missions to our sister planet, Venus. This is the first time in over 40 years that Americans have led a mission to that enigmatic planet. What do they hope to find? Clues to our past…and answers to our future.
One of my favorite things about exoplanet systems is just how weird they can get. It seems that every few months we are treated to another surprise. This time around, NASA's TESS observatory delivered a planet almost three times more massive than Jupiter orbiting around not one, but two stars. As an added bonus: that planet orbits its twin suns closer than the Earth does around the sun. Who wants to take a trip?
Excited by the prospects of the “UFO Report”? As a scientist, I have my doubts. But you can watch UFOS DECLASSIFED: LIVE on Discovery and Science June 30 at 8P where experts discuss what can and can't be explained.
Long ago, our universe was without stars. When that first generation ignited, it completely transformed the cosmos, ripping away the veil of neutral gas that had persisted for hundreds of millions of years. This process, called reionization, is largely mysterious to astronomers. But new research is revealing that the smallest of galaxies may have played the biggest of roles.
Listen folks, I love a good sci-fi movie as much as anyone. Cruising around the galaxy, finding weird stuff, and blowing up aliens--it’s all good. But just because a writer can come up with something, it doesn’t make it possible. I’m sorry to say that we’re going to be bound to our solar system for a really, really long time. As in, probably forever.
