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.
Metal asteroid Psyche has a ridiculously high 'value.' But what does that even mean?
NASA's upcoming Psyche mission could be incredibly valuable — not only for planetary science but also for the budding asteroid mining industry.
Space set to keep people safer during emergencies
Governments and international disaster response teams have long relied on satellites to assess the impacts of disasters such as earthquakes and hurricanes. Now ESA has partnered with ICEYE, a Finnish microsatellite manufacturer, to improve early warning systems for floods and wildfires and extend their geographical coverage globally.
What Would It Take to See Exoplanet Volcanoes?
Even with the clearest image from the best telescope in the world, astronomers still won’t know what they’re looking at. It takes a fundamental understanding of physics, particularly how light works, to glean scientific data from the images that telescopes like the James Webb Space Telescope (JWST) capture. To help with that understanding, a whole group of physics modelers specialize in trying to understand what different scenarios would look like with different telescope technologies. A new paper fits neatly into this mold, where researchers from UC Riverside, NASA Goddard, American University, and the University of Maryland decided to model what they think volcanic activity would look like on an exoplanet around a Sun-like star.
A Sneak Peek at the Next Generation Very Large Array’s New Antennae
The National Radio Astronomy Observatory (NRAO) recently disclosed a prototype radio telescope antennae for its next generation Very Large Array (ngVLA) to a group of press, scientists, engineers, and government and business leaders from the United States and Germany at the end of a workshop held at the Max Planck Institute for Mathematics in the Sciences in Leipzig. While construction on the ngVLA isn’t slated to begin until 2026, this recent unveiling provided an opportunity for mtex antenna technology to present its 18-meter dish, which consists of 76 individual aluminum panels arranged in an 8-sided shape.
Bad weather delays SpaceX Falcon Heavy launch of NASA's Psyche asteroid mission to Oct. 13
Weather on Florida's Space Coast will delay the liftoff of NASA's Psyche mission by at least a day, the agency announced Wednesday evening (Oct. 11).
