Red Dwarf Star
Artist's depiction of the powerful flare that erupted from the red dwarf star EV Lacertae in 2008.
Unlike Earth, Venus lacks a magnetic field to deflect powerful solar outbursts -- as can be seen in this NASA-created image, a still from the video "Dynamic Earth: Exploring Earth's Climate Engine."
This vertigo-inducing, false-color image from NASA's Cassini mission highlights the storms at Saturn's north pole. The angry eye of a hurricane-like storm appears dark red while the fast-moving hexagonal jet stream framing it is a yellowish green. Low-lying clouds circling inside the hexagonal feature appear as muted orange color. A second, smaller vortex pops out in teal at the lower right of the image. The rings of Saturn appear in vivid blue at the top right.
This Hubble photo is of a small portion of a large star-birthing region in the Carina Nebula. Towers of cool hydrogen laced with dust rise from the wall of the nebula.
This computer simulation shows gas from a tidally shredded star falling into a black hole. Some of the gas also is being ejected at high speed into space.
This image of Asia and Australia at night is a composite assembled from data acquired by the Suomi NPP satellite in April and October 2012.
In this composite image, visible-light observations by NASAs Hubble Space Telescope are combined with infrared data from the ground-based Large Binocular Telescope in Arizona to assemble a dramatic view of the well-known Ring Nebula.
A delicate ribbon of gas floats eerily in our galaxy. A contrail from an alien spaceship? A jet from a black-hole? Actually this image, taken by NASA's Hubble Space Telescope, is a thin section of a supernova remnant caused by a stellar explosion that occurred more than 1,000 years ago.
NASA's Hubble Space Telescope caught Jupiter's moon Ganymede playing a game of "peek-a-boo." In this crisp image, Ganymede is shown just before it ducks behind the giant planet.
