Who says you can’t lose your atmosphere to a nearby red dwarf and then grow a new one with the help of volcanic activity? This resilient planet, located 41 light-years from Earth, appears to be thriving again after a rough encounter with its host star.
In addition to filling balloons at birthday parties, helium can be found scattered throughout the cosmos. To date, however, scientists have struggled to detect the ubiquitous element on distant worlds, even though the gas is certain to be there. But that’s now changed, thanks to the discovery of helium on a Jupiter-sized world located 200 light-years from Earth—but that’s only part of the story.

Some of the biggest and brightest stars in the universe are packed within a single cluster, a new study reveals.
NASA scientists have captured a remarkable glimpse of a primordial compact galaxy that came into existence at a time when the Universe was exceptionally young, using the Hubble Space Telescope.
The Hubble Space Telescope took a new image of the Veil Nebula, a supernova remnant from a star that exploded 8,000 years ago, and made this truly spectacular flyover visualization of the beautiful ripple in space that you can see below. In the 3D visualization, red is sulfur, green is hydrogen and blue is oxygen.
Astronomers call Messier 63 the Sunflower Galaxy, because they say its spiral shape resembles the spiral of seeds at the center of a sunflower.
