Intergalactic gas clouds are slightly hotter than they should be, new research claims, and theoretical particles called 'dark photons' could explain it.
Researchers confirmed that the distant galaxies discovered by the James Webb Space Telescope are, indeed, perfectly compatible with our modern understanding of cosmology.
Want to become a published astronomer? All it takes is a spare telescope, or at least a decent internet connection, and plenty of patience.
A wild theory suggests that consciousness may explain quantum mechanics, by forcing the subatomic particles to choose one concrete outcome.
What lurks at the center of a black hole? Studying the space-time ripples from black hole collisions could reveal an answer.
Einstein toyed with the idea of faster-than-light-particles but found that such particles violated a central rule of the universe: causality.
A special type of supernova might be able to destroy a planet's ozone layer years after the initial explosion.
Physicists have measured no changes in time or space for any of the fundamental constants of nature.
We don't really know how the universe was created, though most astrophysicists believe it started with the Big Bang.
There simply isn't enough normal matter to account for the amount of gravitational force needed to hold the universe together, meaning dark matter must be prevalent.
Astronomers have found a way to catch planet-murdering stars red-handed and figured out how long we have until the case grows cold.
New research suggests that a wandering companion may have played a role in Betelgeuse's antics of late 2019.
Researchers have proposed what's perhaps the most exotic explanation to date for the source of the universe's seed magnetic field: cosmic strings.
A model of exotic dark matter suggests that the first stars may have formed not as individuals, but as tiny pockets embedded in gigantic, pancake-like sheets.
Some interpretations of quantum mechanics propose that our entire universe is described by a single universal wave function that constantly splits and multiplies.
In a new paper, scientists outline how we can look for clues any alien visitors to our solar system may have left behind.
Many white dwarfs host planets that may lie within the habitable zones of those stars and may even support life. Now, scientists have outlined how to hunt for that possible life.
A new understanding inspired by string theory shows that our universe may be more stable than we previously thought.
Astronomers know of only a few dozen examples of these active asteroids, but they suspect more are out there — and you can join the hunt.
A team of physicists has found that the remnant of a neutron star merger observed in 2019 has just the right mass to be a strange hypothetical quark star.
If you see a giant red star surrounded by a thick shroud of material, watch out — the star will likely explode within a few years.
Lagrange found that the difference between an object's kinetic energy and potential energy unlocked something deeply profound about the universe.
