Engineers Bradley Pafchek and Matt Rubly examine the COSI (Compton Spectrometer and Imager) detector assembly at Space Sciences Laboratory on July 15, 2026. COSI is an upcoming spacecraft that will measure gamma rays, the highest-energy form of light, to help scientists study energetic phenomena in the Milky Way and beyond.

The box is centered inside the top of a hexagonal white frame. A larger hexagonal silver and black box extends from the bottom of the frame. The person on the left wears a blue cleanroom suit, and the one on the left wears a white one. They both wear hairnets, masks, gloves, and shoe covers. A floor-to-ceiling plastic sheet separates the back of the room, which is full of metal shelving and boxes. || COSI_2026July_19_half_print.jpg (1024x682) [223.9 KB] || COSI_2026July_19.jpg (5000x3333) [4.6 MB] || COSI_2026July_19_half.jpg (2500x1667) [576.0 KB] ||

Astronomers will use data collected by Roman’s wide, deep gaze to study the dark universe and hunt for new worlds.

Like all other planets with magnetic fields, Mercury traps harmful radiation in a belt-like shape. But only sometimes.

Scientists thought Mercury's magnetic field was disrupted by the sun too often to trap a radiation belt, but new analysis of MESSENGER data says that's not always the case.

On July 3, 2026, NASA’s Mars-destined ESCAPADE spacecraft captured photos of Earth and the Moon in visible and thermal infrared light.

NASA’s Psyche spacecraft will get a boost from Mars on Friday, May 15, passing just 2,800 miles (4,500 kilometers) from the planet’s surface at some 12,333

The fifth flight of a NASA-led mission using X-rays to learn more about the sun is scheduled for a daytime launch from Poker Flat Research Range during the first two weeks of May.

While the ground-based survey is now globally recognized, its origins trace back to a proposed space-based mission at the Space Sciences Laboratory (SSL).

Around 12:47 a.m. on Tuesday, the UC Berkeley Space Sciences Laboratory established a connection to radio waves from the Orion spacecraft in NASA’s Artemis II lunar flyby mission.

Larger, more powerful storms on Jupiter produce stronger lightning than on Earth. New measurements could shed light on electrical phenomena associated with thunderstorms on our planet.
