2. Small Magellanic Cloud

The atomic hydrogen gas of the Small Magellanic Cloud, revealed by the Australian Square Kilometer Array Pathfinder telescope, gives researchers a window into the dwarf galaxy’s dynamics. This new radio image of our this galactic neighbor can help researchers understand, for instance, the galaxy’s evolution

3. ‘Standing’ on a Spacewalk

Anchored to the International Space Station with a portable foot restraint, NASA astronaut Joe Acaba prepares to do maintenance on the Canadarm2 robotic arm during a spacewalk in October. Acaba needed the foot restraint to reach the latching end effector, a grappling mechanism at the end of Canadarm2, where he replaced a degraded camera.

4. Curiosity Captures Martian Sunset

NASA’s Mars rover Curiosity captured this sunset shot on Nov. 19, 2017 (US Eastern Time). The six-wheeled robot snapped the photo on Nov. 19 at 7:07 p.m. EST (5:39 p.m. local Mars time, and 0007 GMT on Nov. 20), as the sun was dipping behind the rim of Gale Crater

5. The Bubble Nebula

In this view of NGC 7635, also known as the Bubble Nebula, a “bubble” of stellar wind expands around a massive star. Hot, ionized hydrogen gas illuminates the bubble, which measures about 6 light-years across. The bubble is located in a dark molecular cloud roughly 7,100 light-years from Earth in the constellation Cassiopeia. To the right of the glowing red bubble is the bright blue star HD 115198. Astrophotographer Jeff Johnson captured this image from his backyard in Las Cruces, New Mexico using a Takahashi TOA-130F telescope.
