NASA’s Webb Exposes Complex Atmosphere of Starless Super-Jupiter

An international team of researchers has discovered that previously observed variations in brightness of a free-floating planetary-mass object known as SIMP 0136 must be the result of a complex combination of atmospheric factors, and cannot be explained by clouds alone.

NASA’s SPHEREx Space Telescope Will Seek Life’s Ingredients

Where is all the water that may form oceans on distant planets and moons? The SPHEREx astrophysics mission will search the galaxy and take stock. Every living organism on Earth needs water to survive, so scientists searching for life outside our solar system, are often guided by the phrase “follow the water.” Scheduled to launch […]

NASA Scientists Spot Candidate for Speediest Exoplanet System

Astronomers may have discovered a scrawny star bolting through the middle of our galaxy with a planet in tow. If confirmed, the pair sets a new record for the fastest-moving exoplanet system, nearly double our solar system’s speed through the Milky Way. The planetary system is thought to move at least 1.2 million miles per […]

Discovery Alert: A Planet with a ‘Tail’

The Planet WASP-69 b The Discovery The exoplanet WASP-69 b has a “tail,” leaving a trail of gas in its wake. Key Takeaway  WASP-69 b is slowly losing its atmosphere as light hydrogen and helium particles in the planet’s outer atmosphere escape the planet over time. But those gas particles don’t escape evenly around the […]
