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…
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…
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.
A new computer model is revealing the unseen and often bizarre behaviors of particles streaming around rapidly spinning neutron stars, also known as pulsars.
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:
Jupiter’s moon Europa, with its subsurface ocean, may have what it takes to foster alien life. A mission to this icy moon is on the wishlist of many astronomers, but new research suggests it won’t be easy to land spacecraft there: Its surface seems to be littered with icy spikes, the tallest of which measure five…
Astronomers have confirmed thousands of planets outside our Solar System, but not a single exomoon. New research is bolstering the case for a suspected exomoon first detected last year, but scientists say the evidence is still not definitive.
A German-French probe called MASCOT is now collecting valuable data from the surface of Ryugu, an asteroid located 190 million miles from Earth. But it better get cracking—the shoebox-sized probe has only 16 hours to live.
Astronomers have discovered an object, dubbed “the Goblin,” in the outer reaches of the Solar System. The dwarf planet never gets any closer to the Sun than 6 billion miles, but experts say its orbital configuration points to the existence of a much larger, more distant planet —the elusive Planet Nine.
Japan’s MINERVA-II rovers have sent back a batch of new photos from Ryugu, including a stunning new video taken from the asteroid’s rocky surface.
Scientists disproved a widely accepted idea about neutron stars with a recent observation of a high-energy particle jet.
It’s been 107 agonizing days since NASA last heard from Opportunity, raising fears that the 14-year-old rover has finally expired after being battered by a massive dust storm. The Martian probe may be quiet, but a new photo taken of Opportunity from space is providing some much-needed solace.
The discovery of enigmatic dust storms on Titan means the Solar System’s most exotic moon just took it up a notch.
You might think of black holes as enormous vacuum cleaners, sucking in all the matter and light that ventures too close. But confusingly, scientists normally see stuff leaving the area around a black hole, via jets of matter and light from ripped-apart dust. It’s rare to see matter get devoured.
The tech and science world has had a very interesting week: Researchers have discovered what happens when you give our favorite tentacled, ocean-dwelling friends MDMA, landed rovers on asteroids, confirmed the oldest known animal fossil on the planet, and found something very weird going on with a distant neutron star…
Two landers from the Japan Aerospace Exploration Agency (JAXA) have successfully touched down on the Ryugu asteroid after separating from the Hayabusa2 probe in orbit, and have begun transmitting images from the space rock’s surface.
Say hello to Pi Mensae c—a small, Earth-like planet located nearly 60 light-years from our Solar System. It’s probably not able to sustain life, but it’ll go down in history as the first exoplanet detected by NASA’s new TESS satellite.
Scientists using the Hubble Space Telescope have glimpsed a neutron star unlike any seen before.
How do you know where anything is in space? Sure, you can say, “Oh, that star, it’s the one in the middle of the Big Dipper,” but that’s not very useful in an era of incredible telescopes peeping at galaxies billions of light-years away. On January 1, 2019, scientists will adopt the newest, internationally…
Sitting atop Saturn’s north pole is one of the Solar System’s most striking weather patterns: a rotating, color-changing hexagon slightly wider than Earth. A new study shows there’s another hexagon directly on top of the first one—and that’s weird.
