The amazing Sombrero Galaxy’s glowing central core

The amazing Sombrero Galaxy’s glowing central core

[CLICK ON IMAGE FOR HIS RESOLUTION, Hubble Heritage Team (AURA/STScI /NASA)] Why does the Sombrero Galaxy look like a hat? Reasons include the Sombrero’s unusually large and extended central bulge of stars, and dark prominent dust lanes that appear in a disk that we see nearly edge-on. Billions of old stars cause the diffuse glow […]

New comet makes the scene, just after sunset

[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 […]

Fastest ever spaceship blasted off in 2006, passed the moon in 9 hours and took a decade to reach Pluto

Fastest ever spaceship blasted off in 2006, passed the moon in 9 hours and took a decade to reach Pluto

[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 […]

Saturn with moons Dione and Enceladus, courtesy of a Cassini fly-by

[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 […]

M45: The magnificent Pleiades (seven sisters) star cluster

[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 […]

Neighboring galaxy is same size as our own

[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 […]
