This artist’s illustration shows a giant cloud of hydrogen streaming off the warm Neptune GJ 3470b. The host star’s intense radiation is heating the hydrogen in the planet’s upper atmosphere to a point where it escapes into space. GJ 3470b is losing hydrogen at a rate 100 times faster than a previously observed warm Neptune whose atmosphere is also evaporating away. Image credit: NASA / ESA / D. Player, STScI.

Astronomers have monitored the Eta Carinae binary system for more than two decades. It has been prone to violent outbursts, including an episode in the 1840s during which ejected material formed the bipolar bubbles seen here. Now, using Hubble’s Wide Field Camera 3 (WFC3) instrument to probe the nebula in ultraviolet light, they have uncovered the glow of magnesium embedded in warm gas (shown in blue) in places they had not seen it before. The luminous magnesium resides in the space between the dusty bipolar bubbles and the outer shock-heated nitrogen-rich filaments (shown in red). The streaks visible in the blue region outside the lower-left lobe are a striking feature of the image. These streaks are created when the star’s light rays poke through the dust clumps scattered along the bubble’s surface. Wherever the ultraviolet light strikes the dense dust, it leaves a long, thin shadow that extends beyond the lobe into the surrounding gas. Image credit: NASA / ESA / Hubble / N. Smith, University of Arizona / J. Morse, BoldlyGo Institute.

$This enhanced-color view of Enceladus is largely of the southern hemisphere and includes the south polar terrain at the bottom of the image. Ancient craters remain somewhat pristine in some locales, but have clearly relaxed in others. Northward-trending fractures, likely caused by a change in the moon’s rate of rotation and the consequent flattening of the moon’s shape, rip across the southern hemisphere. The south polar terrain is marked by a striking set of ‘blue’ fractures and encircled by a conspicuous and continuous chain of folds and ridges, testament to the forces within Enceladus that have yet to be silenced. The mosaic was created from 21 false-color frames taken during Cassini’s close approaches to Enceladus on March 9 and July 14, 2005. Images taken using filters sensitive to UV, visible and IR light (spanning wavelengths from 338 to 930 nm) were combined to create the individual frames.
