Scientists have discovered that a supervolcano likely created a mysterious rock formation on Mars some 3 billion years ago.
The dust storm on Mars that broke out at the end of May is now affecting the skies across the entire planet.
Will Mars soon be hidden under a veil of dust? Let's hope not. We explore the current storm and the planet's upcoming close opposition.
A recent experiment to better understand the nature of dark matter constrains a possible "fifth force" of nature to almost zero.
Summer star party season has begun - grab your scope or binoculars, pack a sleeping bag, and come and join the fun!
The nearby Red Planet displays remarkable changes every apparition. As Mars approaches opposition, keep an eye out for some of these differences.
Astronomers have watched the growth of a jet fueled by a shredded star.
A team of scientists says we now have an answer to one of the biggest mysteries of GW170817: after the neutron stars collided, what object was formed?
NASA's Dawn spacecraft has entered a new and final orbit that will take it less than 30 miles above the surface of asteroid Ceres.
A new method of measuring star formation in the earliest galaxies finds that they’re producing more massive stars than expected — a result that could affect our understanding of how galaxies grow their stars.
A new study sheds light on an old mystery surrounding anomalous readings from the Apollo landing sites.
New research shows that interactions between small objects beyond Neptune’s orbit —and not a hypothetical Planet Nine — could be the reason some far-flung solar system objects “detach” from their original orbits.
This week: Stars in the Milky Way's outskirts give clues to our galaxy's history, ancient stellar cities might not be as old as they appear, and the International Dark-sky Association awards its 100th Dark Sky Place.
How massive can a neutron star get? In a recent study, scientists may have identified the most massive neutron star yet — by leveraging observations of its highly irradiated companion.
The Curiosity rover has detected organic molecules in ancient rocks on Mars.
Astronomers have discovered three more red, dusty objects near the Milky Way’s central black hole that could be merged stars.
Two new studies — one by a group of high school students — are investigating the strange environment around Tabby's Star.
New observations have helped astronomers identify the source of a 2,000-year-old supernova explosion. But this blast, and the neutron star that created it, seem to have a curious history that defies explanation.
Don't look now — it's already gone! Asteroid 2018 LA screeched into Earth's atmosphere only 7 hours after its discovery to create a Sun-bright spectacle over South Africa and Botswana.
An innovative technique has allowed NASA's Curiosity Rover to resume drilling Martian rocks. But the partially successful test shows that more work remains to be done.
Scientists propose that Saturn’s meddling helped create the four giant Galilean moons orbiting Jupiter.
As you'll learn in this month's astronomy podcast, Jupiter and Saturn will compete with brilliant Venus for your attention in the late-evening sky.
Planetary scientists think they’ve found wind-built ripples of methane ice on the king of the Kuiper Belt.
Vesta, the brightest asteroid, puts on one of its best shows ever in June, when it shines enough to see without optical aid.
A new analysis of our stellar neighborhood reveals 7 times as much nearby stellar traffic as previously known.
