All the stars, stellar corpses, planets, and other large, massive objects take on spherical or spheroidal shapes. Why is that universal?
Comet A3, also known as Comet Tsuchinshan-ATLAS, has sprung to life since 2024’s last equinox. Here’s how to catch the show for yourself.
The problem of the electroweak horizon haunts the standard model of cosmology and beckons us to ask how deep a rethink the model may need.
A long view of biological survival might point us to new possibilities for finding life elsewhere in the Universe.
Our thermodynamic arrow of time explains why the entropy of any isolated system always increases. But it can’t explain what we perceive.
Although human beings arrived on Earth just ~300,000 years ago, we’ve transformed the entire planet completely. Here’s how we did it.
The jail environment teaches the animals that approaching humans results in a boring and annoying experience.
IceCube just found an active galaxy in the nearby Universe, 47 million light-years away, through its neutrino emissions: a cosmic first.
13.8 columnist Marcelo Gleiser reflects on his recent voyage to Earth’s last wild continent.
The number of planets that could support life may be far greater than previously thought, a recent discovery suggests.
Scientists are working to map out the risks of the permafrost thaw, which could expose millions of people to the invisible cancer-causing gas.
There are at least 15 different types of solid water (ice). Now, scientists believe that there might be a second type of liquid water.
Passing chunks of ice can fertilize ocean waters and play a role in the planet’s carbon cycle.
Mercury, Venus, and Mars are all uni-plate planets, and may always have been. Here’s what’s known about why Earth, uniquely, has plate tectonics.
A new technique that can automatically classify phases of physical systems could help scientists investigate novel materials.
The rewards price to get a free cup of hot coffee at Starbucks is going up.
It’s like radar, but with light. Distributed acoustic sensing — DAS — picks up tremors from volcanoes, quaking ice and deep-sea faults, as well as traffic rumbles and whale calls.
The salinity of the oceans is not just a matter of taste. Saltier water behaves differently, too.
Finding this missing piece of water’s path through the universe offers clues to how it came to be on Earth.
Our Moon is full of craters, basins, and ancient lava flows. But two large lunar Grand Canyons have the same origin: a single, giant impact.
Other plans for the tech: organ banking and deep space travel.
As Uranus approaches its solstice, its polar caps, rings, and moons come into their best focus ever under JWST’s watchful eye. See it now!
A great many cosmic puzzles still remain unsolved. By embracing a broad and varied approach, particle physics heads toward a bright future.
“Not my circus, not my monkeys.”
A new method of mapping migration factors in erratic movements and changing climate.
In the infant Universe, particle physics reigned supreme.
Some microbes can withstand Earth’s most inhospitable corners, hinting that life may be able to survive similarly extreme conditions on other worlds.
