How Should the World’s Governments Respond if We Detect an Alien Civilization?

Science fiction is the realm where people traditionally wrestle with the idea of contact with an ETI (Extraterrestrial Intelligence.) But now, those discussions are migrating from science fiction into more serious realms. Academics are going back and forth, one paper at a time, concerning the response and geopolitical fallout from potential contact with an ETI. …

A Year After a Failed Launch, Firefly Reaches Orbit and Deploys Satellites

Commercial space company Firefly Aerospace successfully launched its Alpha rocket for the first time last weekend, reaching orbit and deploying three satellites. While the latest determination of the satellites’ orbit reveals they may have not been placed in the correct orbit, the company appears to consider the orbit high enough to be considered a success. …

27 to 78 cm of sea Level Rise Could be Locked in From Melting Greenland ice Caps

Recent climate research, published in the Nature Climate Change journal has confirmed that melting icecaps in Greenland will contribute a minimum of 27cm rise in ocean levels even if we collectively stop burning fossil fuels immediately. We have reached a “point of no return”. And what makes it worse is that this is the most …

LICIACube Sends Home Images of the DART Impact and the Damage to Dimorphos

The Light Italian CubeSat for Imaging of Asteroids (LICIACube) has returned a series of close-up images of the asteroid Dimorphos, after last week’s successful impact of the Double Asteroid Redirect Test (DART) probe. LICIACube was built and operated by the Italian Space Agency (ASI), and was designed to capture post-impact imagery for the DART team, …

After Getting Slammed by DART, Asteroid Dimorphos has Grown a Tail

More images and details keep coming in about the asteroid intentionally smashed by NASA’s Double Asteroid Redirection Test (DART) spacecraft last week, and this latest image is stunning. A telescope in Chile called SOAR took an image of the asteroid Dimorphos two days after the impact by DART and found the asteroid is trailing a …

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 …
