Life Has Been Found in a Low-Oxygen, Super-Salty, Sub-Zero Arctic Spring

Once again, life has been found in an environment that would be deeply inhospitable to most organisms living on this planet. Fed by waters that pass through 600 meters (1,970 ft) of permafrost, the sub-zero, salty, virtually oxygen-free Lost Hammer Spring in the Canadian Arctic is one of the harshest places on Earth. Even here, however, … Read more

8-armed Jurassic ‘vampire’ used supersuckers to trap prey, amazing 3D images reveal

A Jurassic vampire squid-like creature used supersuckers to snatch prey out of the water column and lock it in place with a watertight seal, 3D imaging of several fossils reveals. For the first time, scientists used advanced 3D imaging techniques to examine in great detail the prey-snatching suckers of Vampyronassa rhodanica, an extinct relative of … Read more

Photographing Antarctica: Penguins, Seals, and a Total Solar Eclipse

Antarctica is a bucket list destination for countless landscape and wildlife photographers, and for good reason. Dramatic, jagged mountain peaks rise high over colonies consisting of millions of penguins living on the frozen earth below. While photographing Antarctica is a rare experience in itself, photographing a total solar eclipse in Antarctica is akin to winning … Read more

Arecibo observatory scientists help unravel surprise asteroid mystery

Credit: Pixabay/CC0 Public Domain When asteroid 2019 OK suddenly appeared barreling toward Earth on July 25, 2019, Luisa Fernanda Zambrano-Marin and the team at the Arecibo Observatory in Puerto Rico jumped into action. After getting an alert, the radar scientists zoned in on the asteroid, which was coming from Earth’s blind spot—solar opposition. Zambrano-Marin and … Read more

Microwave-size spacecraft will test new orbit between Earth and the moon

The miniscule satellite, called a CubeSat, is about the size of a microwave oven and weighs just 55 pounds (25 kilograms), but it will be the first to test out a unique, elliptical lunar orbit. The CubeSat will act as a pathfinder for Gateway, an orbiting lunar outpost that will serve as a way station … Read more

Artificial photosynthesis can produce food without sunshine

Plants are growing in complete darkness in an acetate medium that replaces biological photosynthesis. Credit: Marcus Harland-Dunaway/UCR Photosynthesis has evolved in plants for millions of years to turn water, carbon dioxide, and the energy from sunlight into plant biomass and the foods we eat. This process, however, is very inefficient, with only about 1% of … Read more

Second segment added to Starship launch tower at Kennedy Space Center – Spaceflight Now

The second section of the Florida launch tower for SpaceX’s huge Super Heavy and Starship rocket was lifted on top of the first tower segment Thursday at the Kennedy Space Center, continuing construction of a structure that will stand more than 400 feet tall. SpaceX transferred the second metal tower segment — itself as tall … Read more
