The sublimation of methane ice into methane gas is leaving a bite-mark feature on the surface of Pluto.

A new study shows that Dark Matter is triggering star formation in dwarf galaxies near the Milky Way.

First observed in the 2nd century CE, the Messier 7 cluster (aka. the Ptolemy Cluster) is one of the objects that can be seen with the naked eye

In addition to its many commercial and scientific uses, helium is one of the most plentiful elements in our universe, second only to hydrogen gas.

When stars explode, it's one of the most energetic explosions in the Universe. But did you supernovae come in different flavors?

Sneaky Mars creeps up on bright Graffias in Scorpius for a very close conjunction Wednesday morning. Even better, the star is one of the prettiest double stars in the sky.

The joint European/Russian ExoMars spacecraft successfully launched early this morning from the Baikonur Cosmodrome in Kazakhstan atop a Proton-M rocket at 5:31:42 a.m. EDT (0931:42 GMT), Monday, March 14, with the goal of searching for signs of life on the Red Planet.

The countdown has begun for blastoff of the ambitious European/Russian ExoMars 2016 spacecraft from the Baikonur Cosmodrome in Kazakhstan on March 14. Its goal is to search for minute signatures of methane gas that could possibly be an indication of life or of nonbiologic geologic processes ongoing today.

An international team of astronomers recently measured the rotation rate of one of the most massive black holes known ... and it's fast! At nearly a third the speed of light, it's one of the fastest spinning things in the universe. The hole powers a quasar visible in amateur telescopes this season.

NASA engineers have successfully test fired the first flight engine destined to power the agency's mammoth new SLS rocket that will launch American astronauts back to the Moon and deep space for the first time in nearly five decades.

A new study from the Lunar and Planetary Laboratory has indicated that the extreme eccentricity of distant KBOs could point the way to the mysterious Planet

Today Cassini will observe the light of the central star in Orion's belt as it passes through Enceladus' plumes.

NASA's MAVEN spacecraft captured the chaotic rendezvous between Mars and comet Siding Spring in 2014.

The Insight Mars lander has been saved from mission termination and will live to launch another day two years from now, NASA managers just announced following a thorough three month investigation into the causes of the last moment snafu involving the failure of its French-built seismometer science instrument that last December forced the agency to cancel its planned liftoff this month.

Hooray for the Mars Reconnaissance Orbiter! Ten years of ground-breaking science (and eye candy.)

The first flight test for the RS-25 rocket engine, which will power NASA's Space Launch System, is set for March 10th.

Martian colonists will need to grow their own food, and researchers in Netherlands are trying to understand how suitable Martian soil will be.

According to new research by an international team of scientists, early galaxies were characterized by mergers (aka. "hookups")
