WatchThe world's most powerful rocket reached a 180-mile-high orbit Monday despite losing an engine, then splashed down north of Hawaii after a mission cut short to three hours.
Analysts expect $6.9 billion in second-quarter revenue, most of it from Starlink. On Thursday, a lockup expires and more than 911 million additional shares can be sold.
By jolting a mix of simple gases with 10,000 volts, a University of Sydney researcher brewed synthetic cosmic dust laced with the carbon-based molecules that form the building blocks of living things.
Samples from the Moon's far side show solar-wind particles struck it harder than the near side — because Earth's magnetic field slows the stream that reaches the hemisphere facing us.
Astronomers at Warwick and Colorado used Hubble's ultraviolet vision to pull four dead stars out of the glare of brighter companions — one just 25 light-years away, now the ninth-closest white dwarf to the Sun.
Astrobotic, Firefly Aerospace and Intuitive Machines will fly four robotic missions in late 2028, each carrying the same trio of instruments to scout dust, radiation and navigation for a permanent human outpost.
The first stage of a Long March 10B booster touched down on a floating platform after lofting a satellite, a milestone that until now only SpaceX had achieved.
The Long March 10B's booster returned to a floating platform after reaching orbit, a milestone Beijing has chased for years as it races the U.S. back to the Moon.
The veteran probe swept within six miles of Torifune, snapping close-ups of a snowman-shaped space rock on the first stop of its extended mission.
Close-up data from the Donaldjohanson flyby reveal a 155-million-year-old relic that tumbles like a spinning top and bears chemical traces of water.
A single Air Force-developed propellant ran both a chemical engine and electric electrospray thrusters in the lab — a dual-mode design that could send briefcase-sized CubeSats to Mars.
Set to launch this fall, the Nancy Grace Roman Space Telescope will use gravitational microlensing to find planets, rogue worlds, black holes and neutron stars across the Milky Way's crowded core.
The world's largest IPO to date saw shares climb dramatically as retail investors joined institutions in bidding up the space company's debut.
New research suggests the most powerful cosmic rays may be ultraheavy atomic nuclei that retain energy better while traveling through space than previously thought.
New research suggests the most powerful cosmic rays could be atomic nuclei heavier than iron, potentially explaining how these extreme particles reach Earth with unprecedented energies.
Veteran spacefarers Randy Bresnik, Luca Parmitano, Frank Rubio and rookie Andre Douglas will fly the mission, targeted for as soon as late 2027, that aims to land humans near the lunar south pole.
Astronomers were stunned to find that XMM-VID1-2075, a massive galaxy formed less than two billion years after the Big Bang, shows no sign of rotation — a trait normally seen only in much older, evolved systems.
Using Australia's ASKAP telescope, a team traced a baffling repeating signal to a white dwarf devouring its companion star — emitting bursts every 1.4 hours that are 100 times more powerful than any seen before.
Jeff Bezos' towering rocket was destroyed Thursday night during a hot-fire test of its seven BE-4 engines. No one was injured, but the launch pad's gantry and one of its lightning towers appear to be gone.
Seventeen transits of rocky world K2-18c revealed atmospheric water, carbon dioxide, and a tentative signal of dimethyl sulfide — a molecule produced almost exclusively by biological processes on Earth.
WatchCommander Reid Wiseman, Victor Glover, Christina Koch, and Jeremy Hansen returned safely to Earth on Friday evening, completing the first crewed lunar orbit in more than 50 years.
22-meter-wide impact discovered by comparing orbital images reveals Moon is still actively changing from ongoing asteroid and comet strikes.
The lunar mission has elicited deep feelings among Americans, particularly in Houston where mission control coordinates the historic return to the Moon.
NASA's most ambitious mission since Apollo carries crew farther from Earth than any humans in over 50 years.
GJ 887 d orbits one of the calmest red dwarf stars known, making it only the second potentially habitable planet within ten light-years of our solar system.
ISRO's Gaganyaan-1 mission will test whether India can become the world's fourth nation to independently launch humans to space, with a half-humanoid robot making the maiden voyage.
NASA's JWST captures the Exposed Cranium Nebula 5,000 light-years away.
