Forty Starlink satellites were destroyed earlier this year in a geomagnetic storm.
Knowing that technology would advance in the future, NASA put some moon rock samples into storage without opening them. Now, they have.
Aerial drone footage was sent to an AI trained to track down space rocks.
The far infrared reveals both the coldest and hottest gas in the Universe, and can teach us what no other wavelength range can.
Is there any good reason for assigning North and South the way we do, or could we have just as easily done the reverse?
The laws of physics state that you can't create or destroy matter without also creating or destroying an equal amount of antimatter. So how are we here?
60% of all potentially dangerous asteroids remain undetected.
To understand the edges of our universe, we’ll need to explore the edges of our own philosophies.

In the night sky for March of 2022, only stars and the Moon, not planets, will greet you. The real show, however, arrives just before dawn.
Despite all that we've learned about the Universe, there remain unanswered, and possibly unanswerable, questions. Could "God" be the answer?
Astronomers used supercomputers and an international network of antennas to create the stunning map.
If dark matter exists in a large halo in our galaxy, made up of particles, then it's passing through us constantly. But how much?
When we look out at the Universe, even with Hubble, we're only seeing the closest, biggest, brightest galaxies. Here's where the rest are.
There's a limit to how large planets can be, and it's only about double the radius of Jupiter. At least, so far.
Despite being the closest planet to the Sun, Mercury "only" reaches 800 °F at its hottest. Venus is always hotter, even at night.
Professional astronomy images are the gold standard. But this Large Magellanic Cloud composite is the amateur community's best image ever.
Our research on a Martian meteorite provides new clues about early surface conditions on the red planet.
Is the multiverse real? It's one of the hottest questions in all of theoretical physics. We invited two astrophysicists to join the debate.
“When molecules misbehave, it can lead to great insight.”
Life is possible because of asymmetries, such as an imbalance between matter and antimatter and the "handedness" (chirality) of molecules.
Out of all the galaxies we know, only a few little ones are missing dark matter. At last, we finally understand why.
The odds are slim, but the consequences would be devastating. Here's what would happen, plus how to avoid it.
The Kardashev scale ranks civilizations from Type 1 to Type 3 based on energy harvesting.
Once science operations begin for James Webb, we'll never look at the Universe the same way again. Here's what everyone should know.
Lake Baikal holds nearly one-fourth of Earth's fresh surface water and is the most scientifically interesting lake on our planet.
A study proposes that an ancient trading network, called the Hopewell tradition, may have been wiped out by what is known as a cosmic airburst.
With 1550 distinct type Ia supernovae measured across ~10 billion years of cosmic time, the Pantheon+ data set reveals our Universe.
Yes, the Universe is expanding, but you might wonder, "How fast is it expanding?"
Please stop calling our Sun an "average star." It is philosophically dubious and astronomically incorrect.
65 million years ago, an asteroid strike caused the 5th great mass extinction. Could we save Earth, today, from a similar event?
