What has Perseverance found in two years on Mars?
Percy has turned up volcanic rocks, signs of flowing water and some of the materials necessary for life. → Read More
Artemis 1’s Orion capsule returned safely to Earth. What’s next?
The first test flight in NASA’s return to the moon Artemis program ended well with the uncrewed capsule splashing down in the Pacific Ocean. → Read More
What Artemis I’s launch means for getting humans back to the moon
The launch of NASA's Artemis I is a giant step toward sending humans back to the moon and heading beyond. → Read More
Mini-Neptunes may become super-Earths as the exoplanets lose their atmospheres
Starlight is eroding the atmospheres of a handful of gassy exoplanets that are a bit smaller than Neptune, gradually exposing the rocky cores within. → Read More
Astronauts might be able to use asteroid soil to grow crops
Researchers grew romaine lettuce, chili pepper and pink radish plants in mixtures of faux asteroid soil and peat moss. → Read More
Six months in space leads to a decade’s worth of long-term bone loss
Even after a year of recovery in Earth’s gravity, astronauts who’d been in space six months or more still had bone loss equal to a decade of aging. → Read More
An otherwise quiet galaxy in the early universe is spewing star stuff
Seen as it was 700 million years after the Big Bang, the galaxy churns out a relatively paltry number of stars. And yet it’s heaving gas into space. → Read More
Seven newfound dwarf galaxies sit on just one side of a larger galaxy
Seven newly found dwarf galaxy candidates are stick to just one side of the large galaxy M81. Astronomers don’t know why. → Read More
Samples of the asteroid Ryugu are scientists’ purest pieces of the solar system
Samples Hayabusa2 brought to Earth from asteroid Ryugu are far fresher than similar types of meteorites that scientists have found. → Read More
A newfound, oddly slow pulsar shouldn’t emit radio waves — yet it does
The highly magnetic neutron star rotates three times slower than the previous record holder, challenging the theorical understanding of these objects. → Read More
The Solar Orbiter spacecraft spotted a ‘hedgehog’ on the sun
In its closest flyby yet of the sun, the Solar Orbiter came within 48 million kilometers of our star, revealing new details. → Read More
Pulsars may power cosmic rays with the highest-known energies in the universe
Earth is pelted by energetic particles from space. The source might be the magnetic remains of massive stars, a new study suggests. → Read More
Why some scientists want serious research into UFOs
Science grapples with unknown phenomena all the time. Investigating UAP and whether they're related to aliens shouldn't be different, researchers say. → Read More
We finally have an image of the black hole at the heart of the Milky Way
New observations from the Event Horizon Telescope reveal the turbulent region around our home galaxy’s black hole, Sagittarius A*, in extreme detail. → Read More
The sun’s searing radiation led to the shuffling of the solar system’s planets
As the young sun’s radiation evaporated gas from its surrounding disk, it triggered a jumbling of the giant planets’ orbits, simulations suggest. → Read More

All of the bases in DNA and RNA have now been found in meteorites
Scientists have detected adenine and guanine in meteorites for decades and seen hints of uracil. But cytosine and thymine had remained elusive. → Read More
U.S. planetary scientists want to explore Uranus and Enceladus next
A report on recommendations for the next 10 years of U.S. planetary science prioritizes sending an orbiter to Uranus and an “orbilander” to Enceladus. → Read More
Here’s how NASA’s Ingenuity helicopter has spent 1 year on Mars
The first flying robot on the Red Planet arrived as a technology demonstration. It’s now a trusty scout for its rover partner, Perseverance. → Read More
New thermal maps of Neptune reveal surprising temperature swings
Neptune's atmospheric temperatures show a global drop and later, a weird isolated spike at the south pole. Scientists don't yet know why. → Read More
