In the center of the galaxy, a celestial object called Sagittarius A* corresponds to a supermassive black hole, which has the mass of four million suns.

This image of Jupiter’s south pole, taken by NASA’s Juno spacecraft, shows cyclones the size of Earth, densely clustered across its surface.

The star at the center of this image, Fomalhaut, is encircled by discs of cosmic dust and gas from comets. It’s visible in the Southern Fish constellation just 25 light-years away from Earth, and is one of the brightest stars in the sky.

Every 53 days, NASA’s Juno spacecraft goes on a two-hour-journey around Jupiter's north and south poles. This series of 14 enhanced-color images shows its trip.

This image, taken by NASA’s Hubble telescope, shows part of a nebula, or cloud of gas, surrounding the star EZ Canis Majoris. Radiation streams out of the massive, violent star, blowing nearby material with stellar winds.

These natural color animations, based on images taken in June 2013 (left) and April 2017 (right), compare Saturn’s north polar region. Over three years, as the planet heads towards summer solstice, the polar hexagon became covered in a yellowish haze, which scientists believe comes from smog particles caused by increased solar radiation.

In this image of Enceladus, one of Saturn’s moons, sunlight along the crescent edge shows its icy ridges and depressions. This photo was taken by the Cassini spacecraft, from 104,000 miles away.
