Hubble Telescope Turns 29, Shares Incredible Photo of Southern Crab Nebula to Celebrate Hubble Telescope Turns 29, Shares Incredible Photo of Southern Crab Nebula to Celebrate

Hubble scientists like to honor the telescope’s birthday with an annual release of 4/20-worthy space porn, and this year’s pic is as stunning as ever. The image, in full below, offers an updated view of the Southern Crab Nebula.

Planet Mercury Has Solid Inner Core About the Same Size as Earth's Planet Mercury Has Solid Inner Core About the Same Size as Earth's

A new analysis has found that Mercury has a solid inner core, just like Earth does. And Mercury’s core is just about the same size as our own planet’s.

What Do Great White Sharks Fear? Murderous Orcas What Do Great White Sharks Fear? Murderous Orcas

If movies were scientifically accurate, here’s how Jaws would pan out: As the film’s signature theme begins to play, a black dorsal fin slinks around the water’s surface. Great white sharks flee in fear as the camera reveals the true menace: a killer whale.

How Did This Tiny Little Star Make Such a Big Sparkle? How Did This Tiny Little Star Make Such a Big Sparkle?

Scientists spotted a superflare larger than some of the hugest solar storms on record—from what seems to be a tiny, almost Jupiter-sized star.

A Modified 747 Helped Spot Evidence of the Universe's First Atomic Bond A Modified 747 Helped Spot Evidence of the Universe's First Atomic Bond

Scientists have spotted evidence of the earliest chemistry in the Universe, thanks to measurements taken from a telescope aboard a modified Boeing 747.

What Do Nuclear Bomb Explosions Sound Like?

On July 16, 1945, scientists first unleashed the energy stored at the center of the atomic nucleus, causing a massive explosion in the New Mexican desert. That bomb’s successors would kill several hundred thousand people, permanently alter the course of international relations, and instill a constant sense of fear…

The Quest for the Most Elusive Material in Physics The Quest for the Most Elusive Material in Physics

Zack Geballe spent months screwing together pairs of polished diamonds at the Carnegie Institution for Science’s Geophysical Laboratory. Theory predicted that squeezed between the diamonds’ tips could be one of the most miraculous substances of modern physics—a material that, at near room temperature, could transport…

Piece of a Comet Found Tucked Inside Meteorite Piece of a Comet Found Tucked Inside Meteorite

Scientists have found a cometary building block in an unexpected place: deep inside a meteorite, according to a new paper.

Gravitational Wave Detectors Spot Two Potential Black Hole Collisions in a Week Gravitational Wave Detectors Spot Two Potential Black Hole Collisions in a Week

Less than two weeks after the gravitational wave detectors turned back on, they’ve already seen evidence of two pairs of colliding black holes.

Why Doesn't the Black Hole Image Look Like the One From Interstellar? Why Doesn't the Black Hole Image Look Like the One From Interstellar?

No one knew what a black hole looked like before today. Sure, we thought we knew, thanks to simulations and the now-famous black hole featured in the movie Interstellar.

What We Learned From the First Black Hole Image What We Learned From the First Black Hole Image

Today, scientists from the Event Horizon Telescope released a picture that will go down in scientific history: the first-ever image of a black hole. But there’s more to science than pretty pictures. Alongside the release, scientists dropped six papers documenting how they created the image and what they’ve already…

Gaze Into the Abyss: The First-Ever Image of a Black Hole Gaze Into the Abyss: The First-Ever Image of a Black Hole

Abandon all hope, ye who enter here: Scientists have presented the first-ever image of a black hole.

Pyroclastic Flows May Spread Swift Death on a Cushion of Air Pyroclastic Flows May Spread Swift Death on a Cushion of Air

Scientists think they’ve figured out how pyroclastic flows, fast-moving bringers of death during volcanic events, can travel such incredible distances and speeds despite the friction between the volcanic material and the ground.

Huge Lava Lamp-Like Blobs Spotted in 40-Year-Old Observations of the Sun Huge Lava Lamp-Like Blobs Spotted in 40-Year-Old Observations of the Sun

Scientists have found lava lamp-like blobs up to 500 times larger than the Earth in the solar wind, in data from a pair of spacecraft that launched in the 1970s.

New Mirror-Like Pools Discovered Deep in the Pacific Ocean

Scientists researching the microbial life on volcanic vents uncovered more incredible ocean landscapes from the seafloor off the coast of California. Just check this out:

We May Get the First Close-Up Image of a Black Hole Next Week We May Get the First Close-Up Image of a Black Hole Next Week

The Event Horizon Telescope, a network of telescopes on mission to observe supermassive black holes at the centers of galaxies, is set to release its first results in a public press conference on Wednesday April 10.

MDMA Made Older Mice Start Socializing Like Teenagers MDMA Made Older Mice Start Socializing Like Teenagers

You might think of young brains as soft clay that can take on new shapes in response to various inputs. But as time passes, the clay hardens and is less workable—and like clay, older brains can be less likely to change in response to new situations. Scientists doing research in mice have realized this analogy seems to…

What Do Mars Rovers Sound Like? What Do Mars Rovers Sound Like?

Before meeting its end in a planet-circling dust storm, the Opportunity rover traversed nearly 30 miles over the perilous Martian surface. In some ways, we traveled along with Oppy thanks to the thousands of images it sent back to Earth. But what did Oppy’s journey sound like?

The Gravitational Wave Detectors Are Turning Back On and We're Psyched The Gravitational Wave Detectors Are Turning Back On and We're Psyched

The LIGO and Virgo gravitational wave detectors are set to resume their hunt for gravitational waves on April 1. This go-around, they’ll be even more sensitive thanks to a set of upgrades to their lasers, mirrors, and other components. This next run will be a big deal—for different reasons than the first two…

Scientists Find Fossilized Fish That May Have Been Blasted by Debris From Asteroid That Ended the Dinosaur Age Scientists Find Fossilized Fish That May Have Been Blasted by Debris From Asteroid That Ended the Dinosaur Age

At one of the most important ancient graveyards on Earth in North Dakota, paleontologists unearthed the fossilized remains of fish seemingly killed by the effects of the asteroid that ended the Cretaceous.
