NASA spacecraft Psyche has captured a stunning image of Mars ahead of a flyby on Friday (May 15).
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.
Scientists are hunting for "unknown unknowns" that could lead us to missing ingredients in our recipe of 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.
Merging black holes and neutron stars have unusual oval orbits prior to colliding and merging, which challenge the laws of physics.
A new recipe of dark matter that interacts with itself could be the solution to three separate and vastly different cosmic puzzles.
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.
"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."
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.
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.
Acting as stellar archaeologists, scientists have found fossilized magnetism on long-dead white dwarf stars, which may help to explain how stars evolve.
"Each interstellar comet brings a little bit of its history, its fossils, from elsewhere."
"Most planetary systems appear as 'peas in a pod.' This is not the case in the TOI-201 system."
Astronomers have discovered that jets from a cannibalistic black hole are erupting with the power of 10,000 suns.
NASA engineers have shut down another instrument on Voyager 1 to preserve the power of the most distant spacecraft ever sent into space.
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.
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.
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.
The Jupiter-bound spacecraft JUICE spotted the interstellar invader comet 3I/ATLAS spraying enough water into space to fill 70 swimming pools a day.
"The discovery of this exceptional object has allowed us to accurately study the nature of the stars at the center of an elliptical galaxy in a remote era of the universe, when the galaxy was still young."
Gravitational waves may have provided the first tantalizing evidence of tiny primordial black holes born during the Big Bang, which could account for dark matter.
"This is the first time we have observed, for a large interval in momentum and for multiple species, this flow pattern in a subset of proton collisions in which an unusually large number of particles are produced."
