Why Saturn’s moon Titan might be less oceanic—and more complex—than thought
For years, scientists believed that Titan, Saturn’s largest moon, hid a vast ocean of liquid water beneath its thick, icy shell.
This idea made Titan...
Why most exoplanets are magma worlds
In astronomy, there is a concept called “degeneracy”.
It has nothing to do with delinquent people, but instead is used to describe data that could...
The first alien civilization we encounter will be extremely loud
For decades, science fiction writers have tried their best to prepare us for eventual contact with aliens. Their efforts are dominated by several recurrent...
Scientists find a crack in a 50-year-old law of the universe
Astronomers may have uncovered evidence that challenges one of the longest-standing ideas about quasars, the brilliant beacons powered by supermassive black holes.
A new international...
Webb finds signs of a thick atmosphere on an ultra-hot super-Earth
Astronomers using NASA’s James Webb Space Telescope have found the strongest evidence yet that a rocky planet outside our solar system can hold on...
Scientists challenge the idea that every galaxy has a black hole
A new study using NASA’s Chandra X-ray Observatory suggests that many small galaxies may not contain supermassive black holes at their centers after all.
This...
Scientists discover a hidden black hole monster from the early universe
Astronomers using NASA’s James Webb Space Telescope (JWST) have uncovered a surprising cosmic impostor lurking in the early universe.
The object, a distant galaxy nicknamed...
A real-life Tatooine: Astronomers spot a rare planet orbiting two suns up close
Astronomers have captured a rare and cinematic sight: a distant planet orbiting not one, but two suns, much like the fictional world of Tatooine...
Scientists draw the first detailed map of the Sun’s “point of no return”
Astronomers have created the first continuous, two-dimensional maps of the outer edge of the Sun’s atmosphere, revealing a dynamic and changing boundary where solar...
Earth may be slowly feeding the moon with water and nitrogen, study finds
The Moon is often seen as a dry, lifeless world covered in dust.
But new research suggests its surface may hold more useful material than...
Scientists capture a rare cosmic dance caused by a rapidly rotating black hole
Astronomers have made an extraordinary discovery that brings one of Einstein’s lesser-known predictions to life.
For the first time, scientists have observed a swirling distortion...
Uranus and Neptune could be “rock giants,” not just ice worlds
For decades, scientists have believed that Uranus and Neptune are “ice giants,” planets made mostly of icy materials like water, ammonia and methane.
But a...

Rogue planet shines with aurora like Earth’s northern lights
Imagine a weather report not from Earth, but from a strange, lonely world drifting through space without a star to orbit.
That is what astronomers...
Comets might have brought water to our planet billions of years ago
The mystery of why Earth has so much water, allowing our "blue marble" to support an astounding array of life, is clearer with new...
Scientists predict possible flare-up of ‘blaze star’ T Corona Borealis
Skywatchers might soon witness a rare celestial event: the potential flare-up of T Corona Borealis, commonly known as the "blaze star."
This star, located in...
Did Mars once have a third, larger moon
We are all familiar with our one Moon but other planets have different numbers of moons; Mercury has none, Jupiter has 95 and Mars...
Scientists find a planet the size of Mars but with the makeup of Mercury
Ultra-short-period planets are small, compact worlds that whip around their stars at close range, completing an orbit — and a single, scorching year —...
