Looking up at the night sky -- expansive and seemingly endless, stars and constellations blinking and glimmering like jewels just out of reach -- it's impossible not to wonder: Are we alone? For many of us, the notion of intelligent life on other planets is as captivating as ideas come.

Astronomers searching for planets using NASA’s Kepler telescope have found an extraordinary family of four. Their orbits are so carefully timed that they provide long-term stability for their planetary system.
Terrific planet-wide thunderstorms on alien worlds far from our own have generated detectable radio bursts. Other such signals have been emitted from the heart of our own galaxy, perhaps due to the destruction of dark matter.
Physicists have now provided the first major results of NASA's Magnetospheric Multiscale (MMS) mission, including an unprecedented look at the interaction between the magnetic fields of Earth and the sun.
A small water jet on the icy moon spews its fiercest eruptions when the moon is farthest from the planet, but overall gas output hardly increases.
A new analysis shows that 1,284 candidate planets are indeed confirmed exoplanets.
NASA's MESSENGER mission has unveiled the first global digital elevation model (DEM) of Mercury, revealing in stunning detail the topography across the entire innermost planet and paving the way for scientists to fully characterize Mercury's geologic history.
A few months back, Luxembourg announced its intention to become a leader in asteroid mining. Now, Luxembourg has revealed the first step in its plan to fill the banking vaults with space-grade platinum: a small, water-powered spacecraft.
It's about 660 million times as massive as our sun, and a cloud of gas circles it at about 1.1 million mph. This supermassive black hole sits at the center of a galaxy dubbed NGC 1332, which is 73 million light years from Earth.
After launching the JCSAT-14 satellite, the first stage of the SpaceX Falcon 9 rocket attempted and succeeded an experimental landing on the “Of Course I Still Love You” droneship in the Atlantic Ocean.
Astronomers have discovered the second-strongest merger shock in clusters of galaxies ever observed.
Currently the best place to search for life beyond the solar system. TRAPPIST-1 is an ultracool dwarf star -- it is much cooler and redder than the Sun and barely larger than Jupiter.
A new paper shows that the recent discoveries of exoplanets combined with a broader approach to the question makes it possible to assign a new empirically valid probability to whether any other advanced technological civilizations have ever existed.
The capture of a burst of high-energy neutrinos from a far-off galaxy heralds a new era in astrophysics.
