Huge Patch of Universe Is Strangely Opaque Despite Its Lack of Galaxies Huge Patch of Universe Is Strangely Opaque Despite Its Lack of Galaxies

The mere fact that we live in a universe boggles my mind every once in a while. But thankfully, our cosmic home is a place that follows rules; the laws of physics seem to agree everywhere, and galaxies are uniformly distributed throughout. Except for in this 300-million-light-year-long region, which seems to be…

The Universe's Oldest Galaxies Could Be Right in the Milky Way's Backyard The Universe's Oldest Galaxies Could Be Right in the Milky Way's Backyard

The Universe’s earliest epochs appear to be written into the small dwarf galaxies orbiting our own galactic home, the Milky Way.

This Exoplanet Is So Hot, It Apparently Tears Apart Water Molecules This Exoplanet Is So Hot, It Apparently Tears Apart Water Molecules

There’s an exoplanet whose surface is so hot, it rips apart water molecules. It’s almost a star, but not quite; it’s an ultra-hot, Jupiter-like world located around 880 light-years from Earth.

Facebook Got Mad at Us, Samsung Note 9, and Ajit Pai: Best Gizmodo Stories of the Week Facebook Got Mad at Us, Samsung Note 9, and Ajit Pai: Best Gizmodo Stories of the Week

First, the bad news: Sunday is the anniversary of the disastrous white supremacist Unite the Right rally in Charlottesville, Virginia, that culminated in a neo-Nazi car attack that killed local woman Heather Heyer and wounded scores of others, as well as resulted in the deaths of two police officers. The organizer of…

Watch NASA Launch Its Sun-Skimming Parker Solar Probe Watch NASA Launch Its Sun-Skimming Parker Solar Probe

The Parker Solar Probe blasted off from Cape Canaveral Air Force Station in Florida on Sunday, setting itself on course to become both the fastest human craft ever launched (in the neighborhood of 430,000 miles per hour) and the first to probe the outer corona of the sun.

Mysterious 'Alien' Radio Signal: Here's What You Need to Know Mysterious 'Alien' Radio Signal: Here's What You Need to Know

You may have seen recent headlines about a strange radio signal picked up by a Canadian telescope. Some go as far as to say it was caused by all-caps ALIENS. 

Report: NASA Needs to Get Moving on Its Plan to Snatch Some Mars Dust Report: NASA Needs to Get Moving on Its Plan to Snatch Some Mars Dust

NASA doesn’t just randomly decide what telescopes and satellites to shoot into space and what planet to study next. Instead, a committee of outside scientists drafts a set of goals and recommendations in what’s called a decadal survey. And though it notes some financial setbacks, a midterm review of the last decadal…

This 'Born-Again' Nebula Appears to Be Inside Out This 'Born-Again' Nebula Appears to Be Inside Out

When some stars get old, they eject gas and dust, forming a cloud of electrically charged material in space called a planetary nebula. These nebulae all tend to have the same layered structure, but a team of scientists recently spotted a kind of planetary nebula that looks to be inside out.

Supermassive Black Hole Stretches Starlight, Proving Einstein Right Again Supermassive Black Hole Stretches Starlight, Proving Einstein Right Again

Albert Einstein’s theory of general relativity is magnificent. For a hundred years, it has consistently predicted all sorts of wacky phenomena scientists have later observed throughout space. One international team is now announcing that a 26-year-long observation campaign has once again confirmed the theory.

One Last Map of the Ancient Universe Revealed From Defunct Spacecraft's Data One Last Map of the Ancient Universe Revealed From Defunct Spacecraft's Data

The astronomers behind a universe-mapping satellite have released the project’s final set of processed data. What you see above is the newest image of the oldest visible light in the Universe—microwave radiation from just a few hundred thousand years after the Big Bang.

Our Neighbor Andromeda May Have Cannibalized Another Galaxy Our Neighbor Andromeda May Have Cannibalized Another Galaxy

Our nearest galactic neighbor, the spiral Andromeda galaxy, seems to have a history of cannibalism. New research suggests that Andromeda gobbled up another large galaxy some two billion years ago.

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.

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…

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.

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.

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.

Astronomers Have Captured First Direct Evidence of an Exoplanet Being Born Astronomers Have Captured First Direct Evidence of an Exoplanet Being Born

At this point, we’ve spotted several thousand exoplanets—there’s nothing super exciting anymore about finding a distant star with several worlds orbiting it. But today, scientists are announcing that they have seen an exoplanet in the middle of forming.
