Far Out

Pismis 24, the star cluster seen here in an image released on Dec. 11, 2006, lies within the much larger emission nebula called NGC 6357, located about 8,000 light-years from Earth. The brightest object in the picture was once thought to be a single star with an incredibly large mass of 200 to 300 solar […]

NASA Sensor on Space Station Eyes Contamination off California Coast

Proof-of-concept results from the mouth of the Tijuana River in San Diego County show how an instrument called EMIT could aid wastewater detection. An instrument built at NASA’s Jet Propulsion Laboratory  to map minerals on Earth is now revealing clues about water quality. A recent study found that EMIT (Earth Surface Mineral Dust Source Investigation) […]

NASA Launching Rockets Into Radio-Disrupting Clouds

NASA is launching rockets from a remote Pacific island to study mysterious, high-altitude cloud-like structures that can disrupt critical communication systems. The mission, called Sporadic-E ElectroDynamics, or SEED, opens its three-week launch window from Kwajalein Atoll in the Marshall Islands on Friday, June 13. The atmospheric features SEED is studying are known as Sporadic-E layers, […]

NASA’s Roman to Peer Into Cosmic ‘Lenses’ to Better Define Dark Matter

A funky effect Einstein predicted, known as gravitational lensing — when a foreground galaxy magnifies more distant galaxies behind it — will soon become common when NASA’s Nancy Grace Roman Space Telescope begins science operations in 2027 and produces vast surveys of the cosmos. A particular subset of gravitational lenses, known as strong lenses, is […]
