The light from Earendel took 12.9 billion years to reach Hubble. The star is millions of times brighter than our Sun and 50 times as massive.
On Nov. 13, 1946, a scientist dropped crushed dry ice from a plane into supercooled stratus clouds.
To study the origin of the Universe, we could build a constellation of six expensive spacecraft — or we could just use the Moon.
Multiple lines of evidence — physical, chemical, and biological — must converge for scientists to conclude that alien life has been found.
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.
60% of all potentially dangerous asteroids remain undetected.
Gigantic ranges called "supermountains" formed twice in Earth's history, and they may have had a profound influence on evolutionary history.
Astronomers used supercomputers and an international network of antennas to create the stunning map.
A new method of extracting rare-earth elements could put us on the track toward a circular economy.
Chemical changes inside Mars' core caused it to lose its magnetic field. This, in turn, caused it to lose its oceans. But how?
Our research on a Martian meteorite provides new clues about early surface conditions on the red planet.
The quadratic formula isn't just something that teachers use to torture algebra students. The Babylonians once used it to calculate taxes.
The Poisson distribution has everyday applications in science, finance, and insurance. To compare the results of some biomedical studies, more people ought to be familiar with it.
The big-picture physics is simple – let gravity do its job.
The pulse took just 35 hours to cover the whole world.
We know more about the universe than what is beneath our feet. But Earth's mantle holds subtle clues about our planet's past.
The inside of every black hole leads to the birth of a new Universe. Could our Universe have arisen from one?
Shooting star or piece of space dust?
Impressive but deadly physics underlie catastrophic eruptions.
With a new telescope on the horizon, we reflect on the best pictures of space that came before.
On December 19 1972, astronauts Eugene Cernan, Harrison Schmitt and Ronald Evans splashed down safely in the Pacific Ocean, ending the Apollo 17 lunar mission. They were the last people to travel […]
A levitating vehicle might someday explore the moon, asteroids, and other airless planetary surfaces.
