Can We Measure Our Own Galaxy Speeding Through Space? Can We Measure Our Own Galaxy Speeding Through Space?

You’re probably sitting still, right? Wrong, absolutely wrong. Not only are you on a spinning orb, but you’re also traveling around 70,000 miles per hour around a star, in a galaxy that, observations imply, is sailing through space at over a million miles per hour.

New South African Telescope Releases Epic Image of the Galactic Center New South African Telescope Releases Epic Image of the Galactic Center

You’re looking at the center of our galactic home, the Milky Way, as imaged by 64 radio telescopes in the South African wilderness.

New Quantum Computer Milestone Would Make Richard Feynman Very Happy New Quantum Computer Milestone Would Make Richard Feynman Very Happy

A commercially available “quantum computer” has been on the market since 2011, but it’s controversial. The D-Wave machine is nothing like other quantum computers, and until recently, scientists have doubted that it was even truly quantum at all. But the company has released an important new result, one that in part…

See the South Pole Message That Alerted Astronomers to the Cosmic-Ray-Spewing Blazar See the South Pole Message That Alerted Astronomers to the Cosmic-Ray-Spewing Blazar

Today, scientists made a huge announcement: Telescopes around the world recorded a source of mysterious, ultra-high-energy cosmic rays, the highest-energy particles that hit the Earth. It all started with a text message.

Cosmic Ray Mystery Finally Cracked Thanks to Supermassive Black Hole Beaming Energy Straight at Earth Cosmic Ray Mystery Finally Cracked Thanks to Supermassive Black Hole Beaming Energy Straight at Earth

Every so often, protons and even entire atomic nuclei strike the Earth with extremely high energies—much higher than what scientists can produce in their most powerful physics experiments. Since the discovery of “cosmic rays” a hundred years ago, no one knew for sure where the most energetic of these particles came…

New Analysis of Potentially Habitable Exoplanet Makes Us Hungry for Better Telescopes  New Analysis of Potentially Habitable Exoplanet Makes Us Hungry for Better Telescopes 

Eleven light-years from Earth, orbiting a dim red star, there’s an exoplanet called Ross 128b that, as we recently reported, has some the best prospects for life of any known distant world. New results may help astronomers figure out what the planet is made of—and they offer more evidence that it might be inside its…

We Asked Celeb Physicist Brian Cox About Flat Earth Conspiracies, the Multiverse, and Ghosts We Asked Celeb Physicist Brian Cox About Flat Earth Conspiracies, the Multiverse, and Ghosts

There’s a growing, bewildering movement of folks who reject the most basic learnings of science in favor of conspiracy theories and hocus pocus—as a science journalist, I regularly get emails from people who firmly believe the Earth is flat, as shocking as that may seem. I recently chatted with Brian Cox, host of BBC…

Listen to the Sound of Saturn's Electromagnetic Energy

Sound and light have way more in common than you think, which is why it’s easy to turn light data, like radio waves, into sound. This can make for some pretty incredible science communicating tools—just look up Jupiter’s whistlers, falling bomb sounds caused by the planet’s lightning; or the chirp of LIGO’s…

Scientists Harvest Hydrogen from Water in Microgravity, a Nifty Trick for Deep-Space Travel Scientists Harvest Hydrogen from Water in Microgravity, a Nifty Trick for Deep-Space Travel

A team of scientists announced they have harvested hydrogen from water in microgravity—a proof-of-principle test that may one day lead to a way to acquire fuel or other resources during a long-distance, crewed space mission.

Meteorite Hunters Find Remains of Last Month's Botswana Fireball Meteorite Hunters Find Remains of Last Month's Botswana Fireball

Last month, a fireball lit up the skies over Botswana just hours after scientists first spotted the space rock hurtling toward Earth. Researchers from Botswana, South Africa, Finland, and the United States have now found pieces of the meteorite.

New Higgs Boson Discovery Could Help Solve Cosmic Puzzle New Higgs Boson Discovery Could Help Solve Cosmic Puzzle

Scientists can’t take pictures of the Higgs boson. But they can find proof of its existence by watching “E=mc2” play out in hundreds of millions of particle collisions per second and detecting how it decays into other particles they do know how to spot. Now, six years after officially discovering the Higgs boson,…

Weird New Quantum Diamonds Offer Hope for a Quantum Internet Weird New Quantum Diamonds Offer Hope for a Quantum Internet

“Diamonds are forever” is a cliche that fails to fully encapsulate the many strange properties of diamonds. But a new kind of diamond, one loaded with impurities, relies on a sort of foreverness that could be useful in future quantum technology—maybe even a quantum internet.

I Do Not Like This New Wasp Species Whose Giant Stinger Lays Eggs Inside Spiders I Do Not Like This New Wasp Species Whose Giant Stinger Lays Eggs Inside Spiders

Hi, do you see that long red thing? It belongs to that wasp. Its function is to both sting and lay eggs inside of another creature, which is eventually killed from the inside by the wasp’s horrifying offspring. I do not like this wasp and hope that I never meet this wasp.

The Earth Is Farthest From the Sun Today, So Why Is It So Hot? The Earth Is Farthest From the Sun Today, So Why Is It So Hot?

All-time heat records have been set around the world this week, in North American cities including Denver, Colorado; Burlington, Vermont; and Montreal, Quebec; as well as in cities in Europe and Russia. But here’s something that might confuse you: Today is also aphelion day—the day in Earth’s orbit that where it’s…

Crows Are Officially More Badass Than Ravens, Citizen Scientists Report Crows Are Officially More Badass Than Ravens, Citizen Scientists Report

Crows and ravens are hard to tell apart, but basically, the common raven is bigger than the American and Northwestern crow. So, you might think that ravens would win in a fight. But that doesn’t seem to be the case.

Jupiter's Moons Leave Signature Spots in Its Aurorae Jupiter's Moons Leave Signature Spots in Its Aurorae

Despite being wildly different from Earth in almost every way, Jupiter does feature some familiar phenomena—including aurorae, what we call the Northern and Southern lights. But Jupiter’s aurorae have something Earth’s don’t: strange features caused by the Jovian moons.

Einstein's Theory of Gravity Holds Up on Test of a Three-Star System Einstein's Theory of Gravity Holds Up on Test of a Three-Star System

Scientists understand gravity pretty well when it comes to two objects, but add a third, and you’ve got chaos—a system that’s impossible to explain with our simplest equations. But you also have a way to test the limits of Einstein’s theory of gravity.

Why Particle Physicists Are Excited About This Mysterious Inconsistency Why Particle Physicists Are Excited About This Mysterious Inconsistency

Scientists haven’t conclusively spotted any new particles since the Higgs boson, and that’s got some people worried—there are a ton of other physics puzzles remaining, many of which would require the presence of a new particle to resolve. But recently, there have been some tantalizing clues of new physics, perhaps a…

Did Something Massive Smash Into Uranus? Did Something Massive Smash Into Uranus?

You might be aware of one of Uranus’ complexities: It spins on its side, and its moons orbit on that same rotated plane. New evidence strengthens the case that Uranus was smashed in a giant collision, resulting in its sideways orientation to its orbital plane and perhaps explaining some of the planet’s other mysteries.

A Tit, an Owl, and Some Parakeets: Winning Pics From the 2018 Audubon Photography Awards A Tit, an Owl, and Some Parakeets: Winning Pics From the 2018 Audubon Photography Awards

Photographing wildlife takes a special combination of patience and talent. Birds make the task even more difficult, since they are experts at flying away and disappearing into tall trees.
