[CLICK ON IMAGE FOR HIGH RESOLUTION / Rogelio Bernal Andreo] Otherwise known as the Belt of Orion, these three blue supergiant stars are hotter and much more massive than the Sun. They lie about 1,500 light-years away, born of Orion’s well-studied interstellar clouds. In fact, clouds of gas and dust adrift in this region have […]
[CLICK ON IMAGE FOR HIGH RESOLUTION, Hubble Legacy Archive, NASA, ESA; Processing: Judy Schmidt] What will survive this battle of the galaxies? Known as Seyfert’s Sextet, this intriguing group …. actually contains only four interacting galaxies. Near the center of this Hubble Space Telescope picture, the small face-on spiral galaxy lies in the distant background […]
Signs of life beyond Earth could be found within a decade under the most optimistic scenarios but the U.S. will need to keep up spending to maintain pace in a 21st century space race, astrobiologists told Congress on Wednesday. Sara Seager, a physics and planetary science professor at MIT and recipient of a 2013 MacArthur […]
Nanoparticles can reveal information held by fingerprints that is currently inaccessible. In particular, they can be engineered to bring antibodies that bind with metabolites contained in the sweat of the fingerprint. These metabolites are breakdown products of the consumption of cocaine or nicotine. When the antibodies recognize the metabolite, they cause a colour change. This […]
[CLICK ON IMAGE FOR HIGH RESOLUTION, Hubble, NASA] Stars, like bees, swarm around the center of bright globular cluster M15. This ball of over 100,000 stars is a relic from the early years of our Galaxy, and continues to orbit the Milky Way’s center. M15, one of about 170 globular clusters remaining, is noted for […]
[CLICK ON IMAGE FOR HIGH RESOLUTION / Constantine Emmanouilidi] In a flash, the visible spectrum of the Sun changed from absorption to emission on November 3rd, during the brief total phase of a solar eclipse. [Normally a spectrum of the sun will show dark lines where where wavelengths of energy for elements have been absorbed […]
[CLICK ON IMAGE FOR HIGH RESOLUTION / credit: Antti Kemppainen Sometimes the sky itself is the best show in town. In January 2007, people from Perth, Australia gathered on a local beach to watch a sky light up with delights near and far. Nearby, fireworks exploded as part of Australia Day celebrations. On the far […]
[CLICK ON IMAGE FOR HIGH RESOLUTION] / Copyright: Leo Aerts This webcam and telescope image of banded gas giant Jupiter shows the transit of three shadows cast by Jupiter’s moons in progress, captured in Belgian skies on Oct. 12 at 0528 UT. Such a three shadow transit is a relatively rare event, even for a […]
[CLICK ON IMAGE FOR HIGH RESOLUTION / NASA/JPL/SSI; Composition: Gordan Ugarkovic] This image of Saturn could not have been taken from Earth. No Earth based picture could possibly view the night side of Saturn and the corresponding shadow cast across Saturn’s rings. Since Earth is much closer to the Sun than Saturn, only the day […]
[CLICK ON IMAGE FOR HIGH RESOLUTION] The bright core and outer reaches of giant elliptical galaxy M60 (NGC 4649) loom large at the upper left of this sharp close-up from the Hubble Space Telescope. Some 54 million light-years away and 120,000 light-years across, M60 is one of the largest galaxies in the nearby Virgo Cluster. […]
