[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. […]
A powerful solar storm set to slam Earth today will make for stunning views of the Northern Lights just before New Year’s Eve. The National Oceanic and Atmospheric Administration’s Space Weather Prediction Center said the “strong” storm could allow the Northern Lights to dip as far south as Oregon and Illinois. NOAA classifies solar storms […]
[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, Ivo Scheggia] A few days ago, a bright fireball was photographed from the Alps mountain range in Switzerland as it blazed across the sky. The fireball, likely from the Taurids meteor shower, was notable not only for how bright it was, but for the rare orange light it created […]
[CLICK ON IMAGE FOR HIGH RESOLUTION, Michael Wilson] This was a sky to show the kids. All in all, three children, three planets, the Moon, a star, an airplane and a mom were all captured in one image near Great Salt Lake in Utah, USA in early September of 2005. Minus the airplane, this busy […]
