Gaze Down Into the eye of Hurricane Ian, Seen From Orbit

NASA and NOAA satellites — as well as astronauts on the ISS — captured some stunning imagery of Hurricane Ian, as seen from orbit. Our lead image shows an eerie view of the hurricane’s eye on September 28. The Landsat 8 satellite passed directly over Ian’s eye as the storm approached southwest Florida. The natural-color …

Scientists Have Been Underestimating the Asteroid That Created the Biggest Known Crater on Earth

Ancient impacts played a powerful role in Earth’s complex history. On other Solar System bodies like the Moon or Mercury, the impact history is preserved on their surfaces because there’s nothing to erase it. But Earth’s geologic activity has erased the evidence of impact craters over time, with some help from erosion. Earth’s complex history …

A Small Piece of “Foreign Object Debris” Fell off Ingenuity’s Leg During its 33rd Flight

We hope this is just as inconsequential as having a piece of toilet paper stuck to your shoe, but images from the Ingenuity helicopter show it had a piece of debris fluttering from its leg during its most recent flight. A blog post from NASA said a small piece of foreign object debris (FOD) was …

The Milky Way is Surrounded by a Vast Graveyard of Dead Stars

Everything dies in the end, even the brightest of stars. In fact, the brightest stars are the ones that live the shortest lives. They consume all the hydrogen they have within a few million years, then explode as brilliant supernovae. Their core remains collapse into a neutron star or black hole. These small, dark objects …

The Bright Core of This Spiral Galaxy Reveals an Actively Feeding Supermassive Black Hole

Hubble Space Telescope observes a lot of galaxies. Some of them are wild-looking while others seem fairly placid. Recently, it looked at NGC 5495, which lies about 300 million light-years away from Earth. You wouldn’t know just by looking at it, but this galaxy has some pretty hot action happening in its core. It’s known …

Earthlike Worlds With Oceans and Continents Could be Orbiting red Dwarfs, Detectable by James Webb

“Go then, there are other worlds than these.” Or so Stephen King said in his famous Dark Tower series. As of yet, none of those worlds are known to be like Earth. But, according to some new simulations by researchers at the National Astronomical Observatory of Japan (NAOJ), finding a genuinely Earth-like world might be …

Construction Begins on the World’s Largest Steerable Radio Telescope

Radio astronomy has been in flux lately. With the permanent loss of the Arecibo telescope in Puerto Rico, a new global power has taken center stage in humanity’s search for radio signals – China. Recently the Chinese announced the start of work on a new milestone telescope, which will eventually make it the biggest moveable …

How Does NASA Plan to Keep Samples From Mars Safe From Contamination (and Contaminating) Earth?

NASA’s Mars Sample Return Mission is inching closer and closer. The overall mission architecture just hit a new milestone when Perseverance collected the first sample that will be sent back. But what happens once that sample actually gets here? NASA and its partner, ESA, are still working on that, but recently they released a fact …
