[CLICK ON IMAGE FOR HIGH RESOLUTION, Bob Franke] Comet C/2014 S2 (PanSTARRS) poses for a Messier moment in this telescopic snapshot from April 18. In fact it shares the 1.5 degree wide field-of-view with two well-known entries in the 18th century comet-hunting astronomer’s famous catalog. Outward bound and sweeping through northern skies just below the […]
[CLICK ON IMAGE FOR HIGH RESOLUTION, STS-132 Crew, Expedition 23 Crew, NASA] The International Space Station is the largest object ever constructed by humans in space. The station perimeter extends over roughly the area of a football field, although only a small fraction of this is composed of modules habitable by humans. The station is […]
[CLICK ON IMAGE FOR HIGH RESOLUTION, Cassini Imaging Team, SWRI, JPL, ESA, NASA] Cassini, a robot spacecraft launched in 1997 by NASA, became close enough in 2002 to resolve many rings and moons of its destination planet: Saturn. At that time, Cassini snapped several images during an engineering test. Several of those images were combined […]
Famed astrophysicist Stephen Hawking and Russian billionaire Yuri Milner just announced a bold new initiative to visit Alpha Centauri — the second-closest star to Earth — within our lifetimes. “For the first time in human history we can do more than just gaze at the stars, we can actually reach them,” Milner told a crowd […]
[CLICK ON IMAGE FOR HIGH RESOLUTION, NASA, ESA, Hubble Legacy Archive; Processed & Copyright: Hunter Wilson] Why is this galaxy so thin? Many disk galaxies are actually just as thin as NGC 5866, pictured above, but are not seen edge-on from our vantage point. One galaxy that is situated edge-on is our own Milky Way […]
[CLICK ON IMAGE FOR HIGH RESOLUTION, NASA/GSFC/Arizona State U./Lunar Reconnaissance Orbiter] On the Moon, the Earth never rises — or sets. If you were to sit on the surface of the Moon, you would see the Earth just hang in the sky. This is because the Moon always keeps the same side toward the Earth. […]
[CLICK ON IMAGE FOR HIGH RESOLUTION, Chris Kotsiopoulos (GreekSky)] A southern exposure and striking symmetry made Lulworth Cove, along the Jurassic Coast of England, a beautiful setting during December’s Solstice. Five frames in this dramatic composite view follow the lowest arc of the Sun, from sunrise to sunset, during the shortest day of the year. […]
[CLICK ON IMAGE FOR HIGH RESOLUTION, ESA/Hubble & NASA and S. Smartt (Queen’s University Belfast), Robert Gendler] This huge swirling mass of stars, gas, and dust occurs near the center of a nearby spiral galaxy. Gorgeous spiral NGC 3521 is a mere 35 million light-years distant, toward the constellation Leo. Spanning some 50,000 light-years, its […]
[CLICK ON IMAGE FOR HIGH RESOLUTION, Yuri Beletsky (Carnegie Las Campanas Observatory, TWAN)] Planet Earth’s horizon stretches across this recent Solar System group portrait, seen from the southern hemisphere’s Las Campanas Observatory. Taken before dawn it traces the ecliptic with a line-up familiar to November’s early morning risers. Toward the east are bright planets Venus, […]
[CLICK ON IMAGE FOR HIGH RESOLUTION, Wally Pacholka (AstroPics.com, TWAN)] You don’t have to be at Monument Valley to see the Milky Way arch across the sky but it helps. Only at Monument Valley USA would you see a picturesque foreground that includes these iconic rock peaks called buttes. Buttes are composed of hard rock […]
