A fireball lights up the night sky over the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile.
This celestial ring is really the planetary nebula Abell 33. The 'diamond' is a nearby star that is serendipitously positioned.
As spotted by the HiRISE camera on board NASA's Mars Reconnaissance Orbiter, this example of "topographic inversion" was caused by an upwelling of ancient lava rising above the surrounding landscape that is more susceptible to erosion.
The Sol 588 (April 2) Curiosity observation of an anomalous light source on the surface of Mars. Interestingly, this example is in a similar location to the April 3 mystery "light source." After analysis, NASA believes that the anomaly is either a cosmic ray hit or a particularly shiny rock.
Image captured by Curiosity's Navcam camera on Sol 593 (April 7) of the mission. The flat-topped rock resembles Australia. Coincidentally, the rover is currently working in "the Kimberly", nicknamed after the Australian region.
This image from the NASA/ESA Hubble Space Telescope reveals a galaxy cluster, known as MACS J0454.1-0300. Each of the bright spots seen here is a galaxy, and each is home to many millions, or even billions, of stars.
An International Space Station astronaut took this photo on March 29, using a 35mm lens on a digital still camera, of this pre-winter storm located just off the coast of southwestern Australia.
Supernova remnant G352.7-0.1 as observed by NASA's Chandra X-ray space observatory and ground-based radio telescopes.
A plant growth chamber bound for the International Space Station inside the Dragon capsule on the SpaceX-3 resupply mission may help expand in-orbit food production capabilities in more ways than one, and offer astronauts something they don’t take for granted: fresh food. Shown here is one of the "pillows" that will be used to grow lettuce seedlings.
The RS-25 engine that will power NASA's new rocket, the Space Launch System (SLS), off the launch pad and on journeys to an asteroid and Mars is getting ready for the test stand.
