TESS has released its most complete view of the sky over Earth, revealing the location of 6,000 potential worlds beyond the solar system.
James Webb Space Telescope maps our universe's largest structure in unprecedented detail
Using the James Webb Space Telescope, astronomers have mapped the "cosmic web" of galaxies, the largest structure in the universe, with unprecedented detail.
We still can't see dark matter. But what if we can hear it?
Black holes smashing together may churn dark matter "butter," scientists say.
NASA's Psyche asteroid probe will fly within 3,000 miles of Mars today: Here's what to expect
NASA's asteroid-bound spacecraft Psyche is headed for an encounter with Mars on Friday (May 15) to get a boost from the Red Planet.
No, this isn't a solar eclipse. It's an image of Mars, captured by NASA's asteroid-bound Psyche probe
NASA spacecraft Psyche has captured a stunning image of Mars ahead of a flyby on Friday (May 15).
What flings mysteriously powerful particles called 'cosmic rays' at Earth?
High-energy cosmic rays, 10 million times more powerful than particles accelerated in Earth's strongest atom smasher, may hide a superheavy secret that is the key to unlocking a 60-year-old puzzle.
'Cannibal stars,' AI and the Rubin Observatory could shed light on the mystery of dark energy. Here's how
Scientists are hunting for "unknown unknowns" that could lead us to missing ingredients in our recipe of the cosmos.
Black holes slamming into scorching stars may be causing mysterious blue flashes in the cosmos
Powerful bright blue cosmic explosions called Luminous Fast Blue Optical Transients could be caused when a black hole or neutron star slams into the universe's hottest class of star.
How do the biggest black holes in the universe form? Ripples in spacetime provide a clue
Merging black holes and neutron stars have unusual oval orbits prior to colliding and merging, which challenge the laws of physics.
3 puzzles of our universe could be solved with this new dark matter theory
A new recipe of dark matter that interacts with itself could be the solution to three separate and vastly different cosmic puzzles.
Artemis Accords: What are they & which countries are involved?
Reference As the Artemis program aims to return humanity to the moon and beyond, the Artemis Accords lay out a framework for nations collaborating in this effort.
What is quantum gravity? Scientists think it could explain the beginning of our universe
A new recipe of "quadratic gravity" could help to better define the picture of the Big Bang and the singularity that existed prior to the dawn of time.
Did decaying dark matter help create the universe's first supermassive black holes?
"With the James Webb Space Telescope now revealing more supermassive black holes in the early universe, this mechanism may help bridge the gap between theory and observation."
This X-ray image shows our solar system 'breathing'
The eROSITA spacecraft has built the most precise map of soft X-rays over Earth, observing a fascinating phenomenon driven by solar winds from the sun.
Famous asteroid Ryugu may have been bombarded by a swarm of tiny space rocks 1,000 years ago
Samples of Ryugu returned to Earth by the Hayabusa2 spacecraft show that the asteroid bears the scars of a recent bombardment by tiny space rocks.
What will happen when our sun starts dying? These 'stellar archaeologists' may have found a clue
Acting as stellar archaeologists, scientists have found fossilized magnetism on long-dead white dwarf stars, which may help to explain how stars evolve.
Interstellar invader comet 3I/ATLAS formed in a world much colder than the solar system
"Each interstellar comet brings a little bit of its history, its fossils, from elsewhere."
NASA's TESS spacecraft discovers a weird system of exoplanets unlike anything seen before
"Most planetary systems appear as 'peas in a pod.' This is not the case in the TOI-201 system."
'Dancing' jets erupting from a cannibalistic black hole have the power of 10,000 suns
Astronomers have discovered that jets from a cannibalistic black hole are erupting with the power of 10,000 suns.
NASA shuts down Voyager 1 instrument to keep probe exploring interstellar space
NASA engineers have shut down another instrument on Voyager 1 to preserve the power of the most distant spacecraft ever sent into space.
Synthetic universe allows you to 'see and hear' galaxies evolving from the dawn of time (video)
Scientists have used a synthetic universe to observe how the first galaxies evolved and grew. In fact, it is so close to the real thing that it's tricking some astronomers.
Interstellar invader comet 3I/ATLAS made a startling transformation as it passed the sun
The interstellar comet 3I/ATLAS changed significantly as it flew by the sun last fall, astronomers have discovered.

Using the James Webb Space Telescope, astronomers have investigated the giant exoplanet 29 Cygni b — work that could clarify the line between planets and stars.
A dark energy tool just created the most comprehensive 3D map of our universe ever: 'This is a major paradigm shift'
The Dark Energy Spectroscopic Instrument has completed its five-year mission to build the most comprehensive 3D map of the universe to date — but its exploration of the universe continues.
