The Case of the Helium-Shrouded Exoplanet With the Hydrogen, Comet-Like Tail

An artist's concept of the vast envelope of atomic hydrogen that envelopes the nearby helium-dominated exoplanet Gliese 436b. The radiation pressure from the planet's host star causes the gradual escape over time of significant amounts of hydrogen from Gliese 436b's atmosphere into space, which subsequently forms a large comet-like tail that follows the planet in its orbit around its star.

SLS Development Engine Test Fire #4 Ignites With Longest Duration Firing Yet

RS-25 development engine test fire at Stennis Space Center near Bay St. Louis, Mississippi. Yesterday's test fire, the fourth in the first series of seven planned test fires, ran for 650-seconds, the longest SLS RS-25 test fire yet. Four RS-25 engines will power the core stage of NASA's new rocket, the Space Launch System. Credits: NASA/Stennis

More Details on Pluto and Charon Emerge in Latest Images as New Horizons Begins Approach Phase 3

A series of images of Pluto, taken by New Horizons' Long Range Reconnaissance Imager, or LORRI, showing numerous large-scale features on the distant planet's surface. These images are displayed at four times the native LORRI image size, and have been processed using a method called deconvolution, which sharpens the original images to enhance features on Pluto.
