In a recent Hubble Space Telescope observation, a double-ringed planetary nebula and massive star have been observed -- this is a star in serious trouble; the fuse has been lit and it could go supernova any day now.READ MORE: Tick, Tick, Tick: Hubble Spies Star Set to Self Destruct
A new observation by NASA's NuSTAR and Chandra space telescopes has been released, depicting a nebula nicknamed the “Hand of God”READ MORE: Spooky 'Hand of God' in Space Reaches for Clouds
On Jan. 9, Orbital Sciences launched its Antares rocket, boosting the company's unmanned Cygnus cargo spacecraft to the International Space Station. Two and a half days later on Sunday, the spacecraft, loaded with supplies and experiments, caught up with the orbiting outpost.PHOTOS: Cygnus Berthing: How to Grapple a Swan in Orbit
NASA astronaut Rick Mastracchio studies the newly-arrived Ant Forage Habitat Facility in the International Space Station's Destiny laboratory.
The ant experiment will study the insect's behavior and colonization in microgravity. The colony arrived on board the Orbital Sciences Cygnus cargo delivery earlier this month.

The company Planet Labs hopes to change the world one mini-satellite at a time. Launched to the International Space Station, the fleet of cubesats called Flock 1 will be put into orbit to begin various Earth-observing projects.READ MORE: Saving the Planet One Tiny Satellite at a Time
On Jan. 16, Mars rover principal investigator Steve Squyres announced the bizarre appearance of a doughnut-sized rock feet from the robot. The leading theory is that Oppotunity's broken wheel flicked it from the bedrock as it was maneuvering, but scientists have yet to definitely say whether or not the rover is to blame.READ MORE: Mystery Rock 'Appears' in Front of Mars Rover

Tracking weather conditions on other planets is no easy task, but if we start playing close attention to dune formation, we could develop a means to at least know which way the wind is blowing. Shown here is wind blown material on Mars that can be used to study wind direction and geological conditions.READ MORE: Sand Dunes Could Reveal Weather on Alien Worlds

A series of observations performed with the ESA/NASA Solar and Heliospheric Observatory (SOHO) to study the evolution of reconnection jets on a small patch of the sun’s surface.
The locations of three rare exoplanets discovered inside the star cluster Messier 67. Once of the worlds orbits a star that looks identical to our sun.READ MORE: Rare Exoplanet Found in Cluster, Orbits Sun's 'Twin'
Long, medium, short and irregular gravity waves have been observed in Venus’ atmosphere by the European Mars Express orbiter -- similar gravity waves can be found on Earth and are often caused by winds blowing over mountain ranges.READ MORE: Mountains on Venus Make Waves in the Sky
