Hubble Space Telescope

The image columns show the change of Uranus for the four years that STIS observed Uranus across a 20-year period. Over that span of time, the researchers watched the seasons of Uranus as the south polar region darkened going into winter shadow while the north polar region brightened as northern summer approaches.

One of the few galaxies with a well-studied stellar halo is our neighbor, Andromeda, depicted here in the graphic. The reason Andromeda’s halo can be investigated so thoroughly is simply a matter of distance, both being close enough and bright enough that we can see the full picture with our current class of telescopes.

LEDA 1313424, aptly nicknamed the Bullseye, is two and a half times the size of our Milky Way and has nine rings — six more than any other known galaxy. High-resolution imagery from NASA’s Hubble Space Telescope confirmed eight rings, and data from the W. M. Keck Observatory in Hawaii confirmed a ninth. Hubble and Keck also confirmed which galaxy dove through the Bullseye, creating these rings: the blue dwarf galaxy that sits to its immediate center-left.

An artificially colored ultraviolet image of Jupiter reveals the Great Red Spot as a striking blue feature, while an oval of concentrated haze appears in the brown haze near the south pole. This dark oval, likely caused by mixing from a high-altitude vortex, mirrors similar but less frequent features seen at the planet's north pole.

This artist's illustration depicts the Large Magellanic Cloud (LMC) in the foreground as it passes through the gaseous halo of the much larger Milky Way galaxy. The encounter has stripped away much of the LMC's spherical gas halo, leaving a trailing gas stream resembling a comet's tail. However, a compact halo remains intact, and scientists predict this residual halo will not dissipate entirely. The research team studied the LMC's halo by analyzing the light from 28 quasars, exceptionally bright active galactic nuclei that act as "lighthouse beacons" across the universe. This light enables scientists to detect the halo gas indirectly, as the gas absorbs some of the quasars' light. The lines in the illustration represent the path of the Hubble Space Telescope's observations, from its orbit around Earth to the distant quasars, passing through the LMC's gas halo.

This is an artist's concept looking down into the core of the giant elliptical galaxy M87. A supermassive black hole ejects a 3,000-light-year-long jet of plasma, traveling at nearly the speed of light. In the foreground, to the right is a binary star system. The system is far from the black hole, but in the vicinity of the jet. In the system an aging, swelled-up, normal star spills hydrogen onto a burned-out white dwarf companion star. As the hydrogen accumulates on the surface of the dwarf, it reaches a tipping point where it explodes like a hydrogen bomb. Novae frequently pop-off throughout the giant galaxy of 1 trillion stars, but those near the jet seem to explode more frequently. So far, it's anybody's guess why black hole jets enhance the rate of nova eruptions.

The ULLYSES program studied two types of young stars: super-hot, massive, blue stars and cooler, redder, less massive stars than our Sun. The top panel is a Hubble Space Telescope image of a star-forming region containing massive, young, blue stars in 30 Doradus, the Tarantula Nebula. Located within the Large Magellanic Cloud, this is one of the regions observed by ULLYSES. The bottom panel shows an artist's concept of a cooler, redder, young star that's less massive than our Sun. This type of star is still gathering material from its surrounding, planet-forming disk.

Image of the asteroid Dimorphos, with compass arrows, scale bar, and color key for reference. The north and east compass arrows show the orientation of the image on the sky. Note that the relationship between north and east on the sky (as seen from below) is flipped relative to direction arrows on a map of the ground (as seen from above).

A Hubble Space Telescope image of the globular star cluster, Messier 4. The cluster is a dense collection of several hundred thousand stars. Astronomers suspect that an intermediate-mass black hole, weighing as much as 800 times the mass of our Sun, is lurking, unseen, at its core. Credits: ESA/Hubble, NASA

The Hubble Space Telescope has captured images of gas-and-dust disks around the young star TW Hydrae. These images show shadows moving across the disks surrounding the system. Scientists believe that these shadows are being cast by inner disks that are slightly tilted and blocking the light from reaching the outer disk. This tilt is due to the gravitational pull of unseen planets that are changing the structure of the disks.
