A dark mystery has settled over the city of Aldastron on the rogue planet of Exlaris. Researchers dedicated to studying the cosmos have disappeared, and the Hubble Space Telescope has vanished from Earth’s timeline. Only an ambitious crew of adventurers can uncover what was lost. Are you up to the challenge?

Taken during instrument calibration, this image helped test Webb's ability to dig up galactic "fossils." Ancient galaxies are so far that as space expands, their light has stretched into infrared wavelengths — Webb's specialty. Did that large spiral galaxy towards the bottom of the image catch your eye? Named LEDA 2046648, it’s a little over a billion light-years from Earth and located in the cons

Impact Site—Cassini's Final Image: This monochrome view is the last image taken by the imaging cameras on NASA's Cassini spacecraft. It looks toward the planet's night side, lit by reflected light from the rings, and shows the location at which the spacecraft would enter the planet's atmosphere hours later.

Astronomers have uncovered a supermassive black hole that has been propelled out of the center of a distant galaxy by what could be the awesome power of gravitational waves. Though there have been several other suspected, similarly booted black holes elsewhere, none has been confirmed so far. Astronomers think this object, detected by NASA's Hubble Space Telescope, is a very strong case. Weighing

This is an artist's concept of a plume of water vapor thought to be ejected off the frigid, icy surface of the Jovian moon Europa, located about 500 million miles (800 million kilometers) from the s

"This change will have ripple effects throughout the solar system." The sun's magne

Jan. 8, 2013: In the galactic scheme of things, the Sun is a remarkably constant star. While some stars exhibit dramatic pulsations, wildly yo-yoing in size and brightness, and sometimes even exploding, the luminosity of our own sun varies a measly 0.1% over the course of the 11-year solar cycle. There is, however, a dawning realization among researchers that even these apparently tiny variations

If a moonbeam wakes you up on the night of May 5th, 2012, you might want to get out of bed and take a look. This May’s full Moon is a "super Moon,” as much as 14% bigger and 30% brighter than other full Moon

High above Earth's surface where the atmosphere meets space, a rarefied layer of gas called "the thermosphere" recently collapsed and now is rebounding again.

This brand new Hubble photo is of a small portion of one of the largest seen star-birth regions in the galaxy, the Carina Nebula. Towers of cool hydrogen laced with dust rise from the wall of the nebula. The scene is reminiscent of Hubble's classic "Pillars of Creation" photo from 1995, but is even more striking in appearance. The image captures the top of a three-light-year-tall pillar of gas and
