Hubble Space Telescope

Slow down, universe.

Twenty years after revealing this nebula's wonky hourglass shape, the Hubble Space Telescope returns its gaze to the Southern Crab Nebula to capture a stunning anniversary image.

Two incredible new images from the Hubble Space Telescope show galaxies in all their shining glory.

A new image from the venerable Hubble Space Telescope shows what happens when two galaxies collide — an experience our own Milky Way will have in a few billion years.

One of the Hubble Space Telescope's most famous images peered even deeper into the cosmos than scientists had thought.

The Hubble Space Telescope has been at work for almost three decades, but it's still learning new skills — like how to squeeze an incredible 15,000 galaxies into a single image.

Astronomers have detected water vapor and evidence of exotic clouds in the atmosphere of a Neptune-mass planet known as HAT-P-26b.

Bright auroras light up Uranus' atmosphere in two newly released photos, which combine observations by NASA's Hubble Space Telescope and the agency's Voyager 2 probe.

Hubble snapped the photo on Monday (April 3), just four days before Jupiter comes into "opposition," forming a straight line with Earth and the sun (with Earth in the middle).

The universe really is expanding faster than scientists had thought, new research suggests.
