New Cassini View of Saturn's A and F Rings

The Cassini Spacecraft gives us another interesting view of Saturn. Saturn’s A and F rings appear bizarrely warped where they intersect the planet’s limb, whose atmosphere acts here like a very big lens. In its upper regions, Saturn’s atmosphere absorbs some of the light reflected by the rings as it passes through. But absorption is […]

Low Surface Brightness Imaging of the Magellanic System

This newly released ESO image reveals a new view of the Large and Small Magellanic Clouds. Each of the thousands of spots in this new image represents a distant star, and the glittering blue holes reveal glimpses of our neighboring galaxies, the Large and Small Magellanic Clouds. Although this image looks as if it was […]

Hubble Views Remnants of a Dead Star DEM L316A

This newly released Hubble image captures the remnants of a long-dead star. These rippling wisps of ionized gas, named DEM L316A, are located some 160,000 light-years away within one of the Milky Way’s closest galactic neighbors — the Large Magellanic Cloud (LMC). The explosion that formed DEM L316A was an example of an especially energetic […]

New Hubble Image

Using gravitational lensing, the Hubble Space Telescope unveils a very cluttered-looking universe filled with galaxies near and far. Celebrating its 50th anniversary this year, the TV series “Star Trek” has captured the public’s imagination with the signature phrase, “To boldly go where no one has gone before.” NASA’s Hubble Space Telescope doesn’t “boldly go” deep […]

New Cassini Image Shows Dione and Epimetheus

This newly released Cassini image shows Saturn’s rings with Dione and Epimetheus off in the distance. Saturn’s main rings, along with its and moons, are much brighter than most stars. As a result, much shorter exposure times (10 milliseconds, in this case) are required to produce an image and not saturate the detectors of the […]

Hubble Views Galaxy NGC 3125

This newly released Hubble image reveals the vibrant core of the galaxy NGC 3125, which is located 50 million light-years away. Discovered by John Herschel in 1835, NGC 3125 is a great example of a starburst galaxy — a galaxy in which unusually high numbers of new stars are forming, springing to life within intensely […]

New Cassini Image of Tethys Above Saturn

This newly released Cassini image provides an illusion of perspective, showing Saturn’s moon Tethys above the planet’s north pole. Tethys (660 miles or 1,062 kilometers across) is actually farther away than Saturn in this image. Lacking visual clues about distance, our brains place the moon above Saturn’s north pole. Tethys, like all of Saturn’s major […]

Hubble Views Starburst Galaxy Named MCG+07-33-027

This newly released Hubble image shows starburst galaxy MCG+07-33-027, which is located 300 million light-years away. This image was taken by the NASA/ESA Hubble Space Telescope’s Advanced Camera for Surveys (ACS), and shows a starburst galaxy named MCG+07-33-027. This galaxy lies some 300 million light-years away from us, and is currently experiencing an extraordinarily high […]

New Hubble- mage of the Crab Nebula

This newly released Hubble image reveals the heart of one of the most visually appealing, and most studied, supernova remnants known — the Crab Nebula. At the center of this nebula the spinning core of a deceased star breathes life into the gas that surrounds it. The Crab Nebula, which lies 6,500 light-years away in […]

Hubble Views Dwarf Galaxy LEDA 677373

This newly released Hubble image shows dwarf galaxy LEDA 677373, which is located about 14 million light-years away. Dwarf galaxies are small, faint collections of stars and gas. Their diverse properties make them intriguing objects to astronomers, but their small size means that we can only explore those that lie closest to us, within the […]

Hubble Views Auroras in Jupiter’s Atmosphere

Using the Hubble Space Telescope, astronomers view vivid auroras on the poles of Jupiter. Jupiter, the largest planet in the solar system, is best known for its colorful storms, the most famous being the Great Red Spot. Now astronomers have focused on another beautiful feature of the planet, using Hubble’s ultraviolet capabilities. The extraordinary vivid […]

VLT Image of Jupiter

In preparation for the July arrival of NASA’s Juno spacecraft, astronomers used ESO’s Very Large Telescope to obtain new infrared images of Jupiter. They are part of a campaign to create high-resolution maps of the giant planet. These observations will inform the work to be undertaken by Juno over the coming months, helping astronomers to […]

Cassini Views Saturn's Rings and the Icy Moon Enceladus

This newly released Cassini image shows Saturn’s rings and the icy moon Enceladus. At first glance, the most obvious features in this image from NASA’s Cassini spacecraft are Saturn’s rings and the icy moon Enceladus. Upon closer inspection, Saturn’s night side is also visible (near top center), faintly illuminated by sunlight reflected off the rings. […]

Hubble Views the Iridescent Interior of NGC 1569

This newly released Hubble image reveals the iridescent interior of one of the most active galaxies in our local neighborhood — NGC 1569, a small galaxy located about eleven million light-years away in the constellation of Camelopardalis (The Giraffe). This galaxy is currently a hotbed of vigorous star formation. NGC 1569 is a starburst galaxy, […]

New Cassini Image of the Planet Saturn

This newly released Cassini image of Saturn was captured this past March. As Saturn’s northern hemisphere summer approaches, the shadows of the rings creep ever southward across the planet. Here, the ring shadows appear to obscure almost the entire southern hemisphere, while the planet’s north pole and its six-sided jet stream, known as “the hexagon,” […]

Cassini Views a Disruption in Saturn's Ring

NASA’s Cassini Spacecraft captures a small disruption in Saturn’s F ring; which was likely caused by the interaction of a small object embedded in the ring itself and material in the core of the ring. A bright disruption in Saturn’s narrow F ring suggests it may have been disturbed recently. This feature was mostly likely […]
