Why is a NASA spacecraft crashing into an asteroid?

CAPE CANAVERAL, Fla. (AP) — In the first-of-its kind, save-the-world experiment, NASA is about to clobber a small, harmless asteroid millions of miles away. A spacecraft named Dart will zero in on the asteroid Monday, intent on slamming it head-on at 14,000 mph (22,500 kph). The impact should be just enough to nudge the asteroid … Read more

Neptune Looks Out of This World in Latest James Webb Telescope Image

Sept. 22, 2022 2:04 pm ET Listen to article (1 minute) It’s Neptune like it hasn’t been seen before.  The National Aeronautics and Space Administration released an image of the planet Tuesday that it said is the clearest view of Neptune’s rings in 30 years, and put the planet in a new light.

One of Webb Telescope’s Tools Has a Glitch

A view of Webb’s secondary mirror, captured during the telescope’s cryogenic testing. Photo: Ball Aerospace The Webb Space Telescope has been dutifully beaming back incredible images of the cosmos since its “perfect” alignment earlier this year—but nothing is entirely perfect, even a $10 billion telescope. One of Webb’s observing mechanisms has apparently run into a … Read more

An Old Moon of Saturn Might Have Put a Ring on It

Saturn’s rings are 100 million years old and are made up of chunks of water ice. Image: NASA/JPL-Caltech/SSI Saturn’s rings are one of the most iconic structures in the solar system, but their genesis has long been up for debate. New research suggests that the spectacular rings may have been born out of the death … Read more

Saturn Ring Mystery Possibly Solved After Four Centuries of Uncertainty

Saturn isn’t the only ringed planet in our solar system, but its iconic girdle of ice and dust is by far the most spectacular. And a new study gives a fresh explanation of how and when Saturn’s rings formed, offering a solution to a mystery that has stymied astronomers ever since Galileo held up his … Read more

The First Object to Visit Us From Another Star System Could Be a Spaceship

You know scientists: They give the coolest possible explanation to the public and then act like nerds and release a paper years later saying something much more mundane. And so it is with the first object to enter our solar system from a different place. Dubbed “Oumuamua,” scientists are still arguing over what the mysterious … Read more

The Webb Space Telescope Snaps Its First Photo of an Exoplanet

The JWST’s size and sensitivity enabled it to collect more light from this planet than any previous observatory has obtained. (Its photo looks grainier than SPHERE’s only because the JWST observes longer, infrared wavelengths.) This allowed Hinkley, Biller and their team to refine the estimate of the planet’s mass, which they peg at about seven … Read more
