Astronomers have spotted a white dwarf that miraculously survived its own thermonuclear detonation, raising questions over how and why these stars create supernovas.
Never-before-seen microbes living deep beneath the permafrost at one of the coldest and saltiest water springs on Earth could provide a blueprint for life on Mars.
Alien life in the deep global ocean of a water world could receive its nutrients through a shell of high-pressure ice around the planet's core.
A rogue black hole wandering the space lanes of our Milky Way galaxy alone could be the smallest black hole yet found.
NASA's Chandra X-ray Observatory spotted enormous shock waves racing away from a collision of two galaxy clusters.
Analysis of Hayabusa2's samples from the asteroid Ryugu shows they date to before the formation of the planets.
The largest near-infrared image of galaxies ever taken by the Hubble Space Telescope has revealed potential targets for the James Webb Space Telescope.
An asteroid demolition derby took place between 7.8 million and 11.7 million years after the birth of the solar system.
A test of whether asteroid surveys could spot a potentially hazardous asteroid successfully rediscovered Apophis and ruled out the possibility of it striking Earth for the next 100 years.
A study of a sample of galaxies that existed up to 12.5 billion years ago has provided further evidence that radiation from active supermassive black holes suppresses star formation.
By employing a new technique to make it easier to see faint gas next to the brilliant glare of a quasar, astronomers have discovered that the quasar is ionizing vast amounts of gas.
Mars is racing toward a new season of dust storms, mighty wind-driven clouds of dust that can cover thousands of square miles or even the entire planet.
Whirling dust devils and occasional but powerful gusts of wind are lifting large amounts of dust into the Martian sky, finds NASA's Perseverance rover.
The LHC's ALICE experiment detected a 'dead cone' in the aftermath of a proton-proton collision, paving the way for the direct measurement of the mass of a quark.
Astronomers used a perhaps unlikely tool to understand what they saw in their historic first image of the Milky Way's supermassive black hole.
The Event Horizon Telescope is ready to take its next steps by capturing movies of gas flowing turbulently onto a black hole.
The Event Horizon Telescope (EHT) has captured a historic first image of the supermassive black hole at the center of our galaxy.
A suspected pulsar is hungrily cannibalizing an unfortunate companion star 3,000 light-years from Earth.
Thirty alien comets have been spotted transiting the young star Beta Pictoris, their long tails lighting up the skies of the fledgling planets forming there.
Pluto is lucky to exist in the orbit that it does, according to new computer simulations that show how the dwarf planet skirts near a chaotic orbit that could potentially destroy the beloved world.
The Chandra X-ray Observatory has found growing intermediate-mass black holes in over two dozen galaxies.
A radio signal designed to bring Earth's climate crisis to the attention of alien life will be beamed to the TRAPPIST-1 planetary system in October.
