We know of stellar mass and supermassive black holes, but intermediate mass ones have long proved elusive. Until now.
On a cosmic scale, our existence seems insignificant and inconsequential. But from another perspective, humans are completely remarkable.
The standard picture of our Universe is that it's dominated by dark matter and dark energy. But this alternative is also worth considering.
From the explosions themselves to their unique and vibrant colors, the fireworks displays we adore require quantum physics.
The structure of our Solar System has been known for centuries. When we finally started finding exoplanets, they surprised everyone.
There are many things that separate science from ideology, politics, philosophy, or religion. Follow these 10 commandments to get it right.
The last infant stars are finishing their formation inside these pillars of gas. The evaporation of those columns is almost complete.
Sure, there's less daylight during winter than summer, as your hemisphere is tilted away from the Sun. But darkness goes deeper than that.
The near and far sides of the Moon are so different from each other, and no one is sure why. New lunar samples could confirm a wild theory.
This research team is working out how to detect extraterrestrial cells in the liquid water ocean hidden beneath Enceladus’s icy crust.
All telescopes are fundamentally limited in what they can see. JWST reveals more distant galaxies than Hubble, but still can't see them all.
There was a time where no starlight was visible throughout the entire cosmos. That time was short-lived: shorter than astronomers imagined.
CERN's NA64 experiment used a high-energy muon beam technique to advance the elusive search for dark matter, offering new hope for solving one of astronomy's greatest mysteries.
The sharpest optical images, for now, come from the Hubble Space Telescope. A ground-based technique can make images over 100 times sharper.
From the coldest planets to spacecraft that have exited the Solar System, these little-known facts stump even many professional astronomers.
Although the Big Bang occurred at an instant in time long ago, we still see the light from it. Will the evidence ever disappear completely?
Known as hypervelocity stars, we originally thought just one would be ejected every 100,000 years. The real number is much greater.
Northern lights in the American South, clusters of huge geomagnetic storms—the Sun is throwing a tantrum right on schedule.
Newborn stars are surrounded only by a featureless disk. Debris disks persist for hundreds of millions of years. So when do planets form?
Out beyond Neptune are some fascinating bodies left over from our Solar System's formation. Could one of them truly be spectacular?
On June 20, 2024, the summer solstice occurs at its earliest moment since 1796: when George Washington was President of the USA. Here's why.
There are two different ways to measure the expansion rate of the Universe, and they don't agree. And no, new measurements don't help.
A new all-time record! JWST's discovery of JADES-GS-z14-0 pushes the earliest galaxy ever seen to just 290 million years after the Big Bang.
The Universe is precisely dated at 13.8 billion years old, but astronomers claim the Methuselah star is 14.5 billion years old. What gives?
Ancient currents seemed to move in concert with a 2.4 million-year dance between the Red Planet and Earth.
Some think the reason fundamental scientific revolutions are so rare is because of groupthink. It's not; it's hard to mess with success.
Scientists are searching for dark matter particles that are trillions or even quadrillion times lighter than the more traditional searches.
In ~7 billion years, our Sun will run out of fuel and die. So will every star, eventually. Here are the different fates they'll encounter.
In 2023, data from the James Webb Space Telescope soured hopes that TRAPPIST-1 c had an atmosphere. That disappointment might have been premature.
The number of planets that could support life may be far greater than previously thought, a recent discovery suggests.
