[CLICK ON IMAGE FOR HIGH RESOLUTION, Yuri Beletsky (Las Campanas Observatory, Carnegie Institution)] A comet has brightened quickly and unexpectedly. Discovered last year, Comet C/2014 Q1 (PanSTARRS) is expected to be visible now for a few days to the unaided eye, just after sunset. The comet rounded the Sun on July 6 and apparently has […]
[CLICK ON IMAGE FOR HIGH RESOLUTION / NASA, Johns Hopkins Univ. / APL, Southwest Research Inst. A 50 mile (80 kilometer) trip across Pluto would cover the distance indicated by the scale bar/ The close-up of the icy world’s rugged equatorial terrain was captured when the New Horizons spacecraft was about 47,800 miles (77,000 kilometers) […]
[CLICK ON IMAGE FOR HIGH RESOLUTION], Ben Cooper Destination: Pluto. The New Horizons spacecraft [atop a powerful Atlas V rocket] roared off its launch pad at Cape Canaveral in Florida, USA in 2006 toward adventures in the distant Solar System. The craft is the fastest spaceships ever launched by humans, having passed the Moon only […]
[CLICK ON IMAGE FOR HIGH RESOLUTION. Image Credit: NASA/JPL-Caltech/Space Science Institute] [This is] Dione, and it’s a moon of Saturn. The robotic Cassini spacecraft took the featured image during a flyby of Saturn’s cratered Moon last month. Perhaps what makes this image so interesting, though, is the background. First, the large orb looming behind Dione […]
Kelly Beatty, Sky and Telescope The two brightest planets are gliding closer together in the early evening sky, and their celestial dance culminates with an ultra-close pairing on June 30th. Anyone who pays even cursory attention to the evening sky has surely noticed that the two brightest planets, Venus and Jupiter, have been drawing closer […]
[CLICK ON IMAGE FOR HIGH RESOLUTION, Marco Lorenzi (Glittering Lights) Perhaps the most famous star cluster on the sky, the bright stars of the Pleiades star cluster can be seen without binoculars from even the depths of a light-polluted city. With a long exposure from a dark location, though, the dust cloud surrounding the Pleiades […]
[CLICK ON IMAGE FOR HIGH RESOLUTION / NASA, JPL-Caltech; Mosaic Processing: Marco Di Lorenzo, Kenneth Kremer] Shortly before Mars’ June 2015 conjunction, the Curiosity Rover celebrated 1000 sols on the red planet. After its Aug. 5, 2012 landing, Curiosity’s 1000th sol or martian day on the surface corresponded to planet Earth’s calendar date May 31, […]
[CLICK ON IMAGE FOR HIGH RESOLUTION, Petri Kehusmaa, Harlingten Atacama Observatory] Large spiral galaxy NGC 4945 is seen edge-on near the center of this cosmic galaxy portrait. In fact, NGC 4945 is almost the size of our own Milky Way Galaxy. Its own dusty disk, young blue star clusters, and pink star forming regions standout […]
[CLICK ON IMAGE FOR HIGH RESOLUTION, Damian Peach/SEN] In this sharp snapshot, the Solar System’s largest moon Ganymede poses next to Jupiter, the largest planet. Captured on March 10 with a small telescope from our fair planet Earth, the scene also includes Jupiter’s Great Red Spot, the Solar System’s largest storm. In fact, Ganymede is […]
[CLICK ON IMAGE FOR HIGH RESOLUTION, Giuseppe Carmine Iaffaldano; Processing: Roberto Colombari] Sculpted by stellar winds and radiation, a magnificent interstellar dust cloud by chance has assumed this recognizable shape. Fittingly named the Horsehead Nebula, it is some 1,500 light-years distant, embedded in the vast Orion cloud complex. About five light-years “tall”, the dark cloud […]
