The photon ring: A black hole ready for its close-up

When scientists unveiled humanity's historic first image of a black hole in 2019—depicting a dark core encircled by a fiery aura of material falling toward it—they believed even richer imagery and insights were waiting ...

Harvesting resources on Mars with plasmas

An international team of researchers came up with a plasma-based way to produce and separate oxygen within the Martian environment. It's a complementary approach to NASA's Mars Oxygen In-Situ Resource Utilization Experiment, ...

Image: ESO telescope images a spectacular cosmic dance

ESO's Very Large Telescope (VLT) has imaged the result of a spectacular cosmic collision—the galaxy NGC 7727. This giant was born from the merger of two galaxies, an event that started around a billion years ago. At its ...

NASA's Europa Clipper spacecraft kicks assembly into high gear

The core of NASA's Europa Clipper spacecraft has taken center stage in the Spacecraft Assembly Facility at the agency's Jet Propulsion Laboratory in Southern California. Standing 10 feet (3 meters) high and 5 feet (1.5 meters) ...

Solar array installed on JPSS-2 satellite

On July 26, in a clean room at the Northrop Grumman facility in Gilbert, Arizona, the National Oceanic and Atmospheric Administration's Joint Polar Satellite System-2 (JPSS-2) let out several loud pops as each of the five ...

Underwater snow gives clues about Europa's icy shell

Below Europa's thick icy crust is a massive, global ocean where the snow floats upwards onto inverted ice peaks and submerged ravines. The bizarre underwater snow is known to occur below ice shelves on Earth, but a new study ...
