Newly Detected Vibrations Show Earth's Inner Core Is Solid Newly Detected Vibrations Show Earth's Inner Core Is Solid

Researchers report that they’ve observed seismic waves traversing the Earth’s inner core, allowing them to figure out what it’s like: solid, but softer than previously thought.

Launching Tonight: A Mission to the Best Planet (Mercury) Launching Tonight: A Mission to the Best Planet (Mercury)

Mercury is the best planet, in my humble but well-researched opinion. Sure, it may be small, rocky, and lacking an atmosphere, but how it came to look the way it does absolutely baffles scientists. It might even have water and carbon hidden away from the beginning of the Solar System. Tonight, scientists from the…

Trying to Understand the Size of This New Space Discovery Will Short-Circuit Your Brain Trying to Understand the Size of This New Space Discovery Will Short-Circuit Your Brain

Light’s speed limit means that looking into the distance is the same as looking into the past: The farther incoming light travels, the older it is. Out in the distance, scientists have spotted a truly enormous, ancient “proto-supercluster,” dubbed Hyperion, which could help explain how the universe forms some of its…

There's Now a Proven Way for Quantum Computers to Beat Classical Computers—With a Catch There's Now a Proven Way for Quantum Computers to Beat Classical Computers—With a Catch

Entrepreneurs and physicists are pursuing a new kind of computer—one based on the physics of the subatomic particles—that promises to revolutionize various fields. Presumably, such a quantum computer should offer some advantage over the classical computers we already use, right? The trouble is, it’s unclear what tasks…

Scientists Release Result from 'Astonishing' Feat of Creating and Testing Quantum Gas in Space Scientists Release Result from 'Astonishing' Feat of Creating and Testing Quantum Gas in Space

Last year, graduate student Dennis Becker watched from a safehouse as the MAIUS-1's sounding rocket took off from a launch facility in the Swedish Arctic. But even after repeated delays from snow and wind, he wouldn’t know for a few days whether the rocket’s payload survived. When the ambitious experiment dropped back…

We Could Solve the Mysteries of Time and Space—If We Had a Particle Accelerator the Size of the Solar System

Gravity is incredibly weak. Just think: You can lift your foot despite the mass of the entire Earth pulling against it. Why is it so weak? That’s unclear. And it might take a very, very big science experiment to find out.

A Visit to One of the Most Powerful Lasers on Earth A Visit to One of the Most Powerful Lasers on Earth

BERKELEY, CALIFORNIA—The winners of this year’s Nobel Prize in Physics didn’t just make discoveries. Their revolutionary work turned powerful lasers into ubiquitous lab tools. The day of the announcement earlier this month, I’d already planned to visit the tennis-court sized Berkeley Lab Laser Accelerator, or BELLA,…

Ey, I’m Mista Real New Yawka from Da Big Apple, da biggest city in da whole woild. I tawk like “dis” and rememba da good old days when Ess-A-Bagel had da best bagel in da City and you’d neva eva think about gettin dat inna tube from da wiseguys at Stawbucks.

NASA's Flagship X-Ray Telescope Back Online After Last Week's Safe Mode NASA's Flagship X-Ray Telescope Back Online After Last Week's Safe Mode

One of NASA’s flagship telescopes, the Chandra X-Ray Observatory, went into safe mode last week following gyroscope problems. That telescope is now back up and running.

Drunk Pigeon Is All of Us, as Well as New Zealand's Bird of the Year Drunk Pigeon Is All of Us, as Well as New Zealand's Bird of the Year

New Zealand has some weird birds, and they know it. Sure, you’ve probably seen the Seussian kiwi, but what about the kākāpo, a flightless parrot that looks like a particularly friendly owl? Have you heard of the morepork, an owl so named because it sounds like it shouts “MORE PORK,” or the wrybill, the only bird with…

New Supernova Discovery Explains Landmark Neutron Star Collision New Supernova Discovery Explains Landmark Neutron Star Collision

August 17, 2017 heralded one of the most important observations in astronomy’s history: two neutron stars colliding, sending both light and gravitational waves toward the Earth. But it left one question wide open: how two of these stellar corpses could have ended up orbiting each other in the first place.

String Theorists' Heads Bobble Over Potential Dark Energy Wobble String Theorists' Heads Bobble Over Potential Dark Energy Wobble

Harvard physicist Cumrun Vafa is one of string theory’s strongest proponents. But this summer, other string theorists have been reeling from his latest conjecture, which might invalidate their ideas built on a decade-long assumption that dark energy is constant. Vafa’s work implies that dark energy’s value changes.

Astronomers Wonder: Can Moons Have Moons? Astronomers Wonder: Can Moons Have Moons?

Inquisitive kids ask some questions that parents just can’t answer. Astronomer Juna Kollmeier’s son gave her a real stumper one night back in 2014:

Most Commercial Graphene Is Just Expensive Pencil Lead, New Study Finds Most Commercial Graphene Is Just Expensive Pencil Lead, New Study Finds

You might wonder why, given all the hype, there isn’t graphene in every product you own yet. Well, a new study has found that 60 companies that sell the Nobel prize-winning ultra-thin carbon sheets produce utter trash.

Voyager 2 Detects Hints That Interstellar Space Is Nearby Voyager 2 Detects Hints That Interstellar Space Is Nearby

Six years ago, the Voyager 1 spacecraft informed scientists that it had become the first man-made object to enter interstellar space. Now, Voyager 2 has begun to return signs that its own exit from the Solar System could be coming soon.

Scientists Work to Keep Hubble Telescope Functioning After Another Gyroscope Fails Scientists Work to Keep Hubble Telescope Functioning After Another Gyroscope Fails

The Hubble Space Telescope entered safe mode over the weekend as scientists figure out what to do after a component failed. But it’s not the end of the famous telescope’s life just yet.

Michigan Man Discovers His Doorstop Actually a Meteorite Worth $100,000 Michigan Man Discovers His Doorstop Actually a Meteorite Worth $100,000

A Michigan man recently learned that this 22-pound rock he used for decades as a doorstop on his farm was in fact a meteorite worth over $100,000.

More Than 200 Physicists Denounce Sexist Lecture at CERN More Than 200 Physicists Denounce Sexist Lecture at CERN

A group of 19 physicists penned a statement denouncing the talk given last week by Italian physicist Alessandro Strumia at a workshop on women in high energy physics held at CERN in Switzerland. More than 200 physicists, including Nobel Prize winner David Gross and several prominent physicist-authors, and at least 850…

Cassini Grand Finale Reveals Saturn's Rings Blast the Planet With Organic Rain Cassini Grand Finale Reveals Saturn's Rings Blast the Planet With Organic Rain

The Saturn-orbiting Cassini-Huygens spacecraft died fighting—in fact, it kept gathering data right up until its final plummet into the gas giant. The daring plunge revealed incredible new things about the charismatic planet—like organic ring rain.

We Regret to Inform You the Large Hadron Collider Will Not Annihilate Earth We Regret to Inform You the Large Hadron Collider Will Not Annihilate Earth

There’s a tired, much-debunked doomsday theory pushed by British physicist Martin Rees that powerful particle colliders have the potential to destroy Earth. They don’t. However, since the story has once again turned up as a top Google News hit, we will deign to debunk it once more.
