After a week of rampant speculation, astronomers have officially announced the discovery of Proxima b, a potentially habitable world circling our nearest neighboring star. But even as engineers prepare for an interstellar voyage to scope out Proxima b for signs of life, some experts warn that M dwarf systems like…
Rumors are flying that astronomers at the European Southern Observatory have discovered an Earth-like exoplanet in the habitable zone of Proxima Centauri, our nearest neighboring star. If confirmed, this is undeniably one of the biggest astronomical discoveries of the century.
Reminding us of our own fragile mortality, a large, bright comet just streaked across the sky and straight into our nearest neighboring star. You will absolutely believe what happened next because it has happened to you in a nightmare, admit it.
Reason number 9,000 not to colonize Jupiter’s moon Io: not only is it a frigid hellscape covered in eruptive ice volcanoes and lashed by the gas giant’s powerful radiation belts, but the atmosphere just collapsed.
Ceres, the tiny asteroid belt world we’ve come to know and love through NASA’s Dawn mission, seems to delight in mysteries, from flickering bright spots to unexpected ocean minerals. Now, astronomers have discovered yet another puzzle while examining images of Ceres’ surface. Something has been erasing its craters.
Four billion years ago, an endless barrage of space rock pummeled the surface of the Earth and the Moon, in a period known as the Late Heavy Bombardment. Now, astronomers have performed a detailed analysis of one of the most famous craters from that time, and what they’ve learned could rewrite the most violent chapter…
Venus’s unusually thick atmosphere is typically regarded as a barrier that prevents us from gazing upon its tortured surface. By studying subtle shifts in weather patterns, however, scientists have learned that these clouds also offer important clues as to what lies beneath.
NASA has spotted something strange and beautiful in the sands of Mars—a remarkable dune field that looks eerily similar to Morse code. And it has a message for us.
Explorers hoping to find easily accessible liquid water on Mars may be out of luck. A new study questions the source of recently discovered surface water on the Red Planet, a revelation that may force Martian colonists to settle in the arctic regions where ice is plentiful.
Saturn’s moon Titan is a frigid hellscape by Earth standards, but it’s also one of the most hopeful spots for discovering alien life in our solar system. A new scientific paper hints that conditions on Titan’s surface might be favorable for the chemistry of life to emerge.
Phobos and Deimos, Mars’ lumpy, runty moons, were once pegged as captured asteroids. But the truth is shaping up to be far more interesting. These ruddy satellites could be the lone survivors of a giant impact that eviscerated half of Mars’ surface billions of years ago.
Before it powered down in preparation for the big engine burn last night, NASA’s Juno spacecraft captured some absolutely stunning footage of the four Galilean satellites in orbit around Jupiter.
After five years and 445 million miles, NASA’s Juno mission arrives in orbit around Jupiter on Monday to begin an unprecedented scientific study of the behemoth planet that shaped our solar system.
As NASA’s Juno mission continues to hurl itself toward Jupiter, the terrifying reality of flying close to the biggest and baddest planet in our solar system is starting to set in. Yesterday, the Jet Propulsion Laboratory dropped recordings the spacecraft created based on data it collected as it crossed Jupiter’s “bow…
If you want to see beautiful auroras, forget Alaska, Canada, and Iceland—check out Jupiter. At the gas giant’s north pole, the most powerful and luminous northern lights in the solar system shimmer and glow in an endless geomagnetic storm that’s larger than our entire planet.
After months of rampant speculation, scientists announced late last year that the bright spots on dwarf planet Ceres are giant deposits of salt. Case closed, right? Not exactly. We’ve since gotten a better look at the spots, and the craters they reside in, and Ceres is shaping up to be a much weirder place than we…
Three hundred and sixty five million miles away sits a cloud of gas so large it weighs more than Saturn, Uranus, and Neptune combined. It’s so powerful it’s been accused of slinging entire planets into the sun, and so ancient it could hold the key to the origin of Earth.
On July 4th, NASA’s Juno spacecraft will arrive in orbit around Jupiter for a new scientific mission that seeks to solve the decades-long mystery of what lies beneath the gas giant’s swirling cloud tops. As the latest stunning image from the spacecraft’s approach shows, we’re getting really fucking close.
New findings from NASA’s Curiosity Rover provide evidence that significant amounts of oxygen once permeated the atmosphere of ancient Mars. The Red Planet, it would seem, was more Earth-like than we thought.
