SpaceX Falcon Heavy rocket poised to launch Psyche metal asteroid mission (photos)
SpaceX's powerful Falcon Heavy rocket is standing tall on the launch pad ahead of the planned Friday (Oct. 13) liftoff of NASA's Psyche metal asteroid mission.
South Korea set to finalize cancellation of launch contracts with Russia
International sanctions imposed against Russia following the country's invasion of Ukraine mean that a pair of satellites due to fly on Russian rockets in 2022 will need to find a new route to space.
TRAPPIST-1 Has Flares. What Does This Mean for its Planets?
The TRAPPIST-1 system continues to fascinate astronomers, astrobiologists, and exoplanet hunters alike. In 2017, NASA announced that this red dwarf star (located 39 light-years away) was orbited by no less than seven rocky planets – three of which were within the star’s habitable zone (HZ). Since then, scientists have attempted to learn more about this system of planets to determine whether they could support life. Of particular concern is the way TRAPPIST-1 – like all M-type (red dwarf) stars – is prone to flare-ups, which could have a detrimental effect on planetary atmospheres.
A leak on the ISS canceled his spacewalk. But an astronaut says that was the right call
European Space Agency astronaut Andreas Mogensen was supposed to step into space Oct. 12. Now facing a delayed spacewalk, he said that was the right call.
Two Worlds Have Ended in a Planetary Collision — and a New One Has Begun
A star's sudden brightening and, two years later, its sudden dimming point to a cataclysmic collision between two large worlds.
Mysterious magnetism in Apollo moon rocks is natural in origin, new study finds
New research finds spaceflight does not adversely affect moon rock magnetism, disproving one of two major oppositions to the moon dynamo theory.
More JWST Observations are Finding Fewer Early Massive Galaxies
There’s a common pattern in science. We develop some new process or tool that allows us to gather all kinds of data we’ve never had before, the data threatens to overturn all we’ve assumed about some long-established theory, and then the dust settles. Unfortunately, the early stage of this process generates a lot of sensationalism in the press. Early results from the JWST are a good example of this.
OSIRIS-REx Returned Carbon and Water from Asteroid Bennu
Carbon and water are so common on Earth that they’re barely worth mentioning. But not if you’re a scientist. They know that carbon and water are life-enabling chemicals and are also links to the larger cosmos.
India's Aditya-L1 solar observatory on course for its sunny parking spot 1 million miles from Earth
India's first solar observatory has made a trajectory correction maneuver to ensure it is on course for a special point in space where it will observe the sun.
Where to Watch the October 14th Annular Solar Eclipse Online
If you can't see the annular solar eclipse in person, we've got some online viewing opportunities for you.
Rocket booster parts arrive in LA to stand up space shuttle Endeavour exhibit
They may not be as iconic as Endeavour or as large as the orbiter's external tank, but the sight of twin rockets moving through the streets of Los Angeles was enough to once again draw a crowd.
How to make roads on the Moon
When astronauts return to the lunar surface they are probably going to be doing more driving than walking – but to keep billowing moondust at bay they are going to need roads. An ESA project reported in today’s Nature Scientific Reports tested the creation of roadworthy surfaces by melting simulated moondust with a powerful laser.
Follow the annular solar eclipse this week with SkySafari
Popular astronomy app SkySafari has added a special set of features for tracking and viewing this week's annular solar eclipse, available for iOS users.
Astronomers See the Afterglow Where Two Ice Giant Planets Collided
What would happen if two giant planets collided? It would be terrifying to behold if it happened in our Solar System. Imagine if Neptune and Uranus slammed into each other. Picture the chaos as a new super-heated object took their places, and clouds of debris blocked out the Sun. Think of the monumental destruction as objects are sent careening into each other.
What are different types of clouds and how do they form?
There are 10 primary types of clouds on Earth. Here you can learn about what they're made of, how they form and how they are classified.
The Incredible Adventures of the Hera mission – Testing times
Video: 00:03:42
Meet Hera, our very own asteroid detective. Together with two CubeSats – Milani the rock decoder and Juventas the radar visionary – Hera is off on an adventure to explore Didymos, a double asteroid system that is typical of the thousands that pose an impact risk to planet Earth.
Hubble Telescope discovers thousands of hot stars camouflaging a spiral galaxy (photo)
Pink splotches of young star clusters disguise a barred spiral galaxy in a new photo from the Hubble Space Telescope.
Mysterious radiation bursts could be coming from 'starquakes' on neutron stars
These starquakes in space could help us study earthquakes at home.
Hubble Telescope Witnessed Intergalactic Flash of Light
An explosive flash of blue light briefly appeared in intergalactic space, thousands of light-years from the nearest galaxy.
What time is the annular solar eclipse on Oct. 14?
An annular solar eclipse will be visible across the U.S. on Oct. 14. Here we look at what time the eclipse will start and where it can be seen.
