Explosions from White Dwarf Star RS OphIllustration Credit & Copyright: David A. Hardy & PPARC Explanation: Spectacular explosions keep occurring in the binary star system named RS Ophiuchi. Every 20 years or so, the red giant star dumps enough hydrogen gas onto its companion white dwarf star to set off a brilliant thermonuclear explosion on the white dwarf‘s surface. At about 5,000 light years distant, the resulting nova explosions cause the RS … Read more

Abell 3827: Cannibal Cluster Gravitational LensImage Credit: ESA/Hubble & NASA, R. Massey Explanation: Is that one galaxy or three? Toward the right of the featured Hubble image of the massive galaxy cluster Abell 3827 is what appears to be a most unusual galaxy — curved and with three centers. A detailed analysis, however, finds that these are three images of the same background … Read more

Stunning view of spiral galaxy by ESA Hubble

This jewel-bright image from the NASA/ESA Hubble Space Telescope shows NGC 1385, a spiral galaxy 68 million light-years away from Earth, which lies in the constellation Fornax. The image was taken with Hubble’s Wide Field Camera 3 (WFC3), which is often referred to as Hubble’s workhorse camera, thanks to its reliability and versatility. It was … Read more

Topic: Astronomers found a crumb of star moving through Milky Way at very high speed A chunk of stellar shrapnel is careering toward the edge of our Milky Way galaxy at almost 2 million mph (3.2 million kph), a new study reports. “The star is moving so fast that it’s almost certainly leaving the galaxy,” … Read more

A new Star Cluster discovered by Italian astronomers

A new Star Cluster discovered by Italian astronomers

Topic: A new Star Cluster discovered by Italian astronomers Astronomers from Italy report the detection of a new star cluster as part of the YMCA (Yes, Magellanic Clouds Again) survey. The newly discovered stellar grouping, designated YMCA-1, may be an old and remote star cluster of our Milky Way galaxy. The finding is detailed in … Read more

Astronomers discovered second-coldest Exo-planet

Astronomers discovered second-coldest Exo-planet

Topic: Astronomers discovered second-coldest Exo-planet Astronomers have discovered thousands of exoplanets—planets beyond our solar system—but few have been directly imaged, because they are extremely difficult to see with existing telescopes. A University of Hawaiʻi Institute for Astronomy (IfA) graduate student has beaten the odds and discovered a directly imaged exoplanet, and it’s the closest one … Read more

Astronomers Captured clearest image of Andromeda galaxy

Astronomers Captured clearest image of Andromeda galaxy

By: University of British Columbia Scientists have published a new, detailed radio image of the Andromeda galaxy—the Milky Way’s sister galaxy—which will allow them to identify and study the regions of Andromeda where new stars are born. The study—which is the first to create a radio image of Andromeda at the microwave frequency of 6.6 … Read more
