Spitzer Telescope Sends Rose for Valentine's Day

Carina Nebula

Black Hole Wind. A composite x-ray/optical image of the active NGC 1068 galaxy reveals an enormous plume of hot gas emanating from the supermassive black hole at the galaxy's center. Scientists think the shape and speed of the plume, which moves at about 1 million miles an hour, are caused by the funneling effect of a doughnut-shaped ring of cooler gas and dust that surrounds the black hole.

The “Black Widow” pulsar is moving through the galaxy at a speed of almost a million kilometers per hour. A bow shock wave due to this motion is visible to optical telescopes, shown in this image as the greenish crescent shape. The pressure behind the bow shock creates a second shock wave that sweeps the cloud of high-energy particles back from the pulsar to form the cocoon.

NASA's GALEX reveals the largest-known spiral galaxy. The spectacular barred spiral galaxy NGC 6872 has ranked among the biggest stellar systems for decades. Now a team of astronomers from the United States, Chile and Brazil has crowned it the largest-known spiral, based on archival data from NASA's Galaxy Evolution Explorer (GALEX) mission, which has since been loaned to the California Institute of Technology, Pasadena, Calif.

Updated 01/12/2013 @ 10:20 UTC Solar Update / Impulsive M1.7 Flare Sunspot 1654 is the largest Sunspot on the visible solar disk, however it is Sunspot 1652 currently producing much of the activity. Another impulsive solar flare, this time reaching M1.7, was detected at 08:38 UTC early Sunday morning.

#Orion #Nebula. If the Orion Nebula was as close to earth as our nearest star (4 lightyears) it would cover the entire sky, so the only thing you'd be able to see is the sun rising and the Orion Nebula

The Sword Of Orion

♥ Nacreous Cloud over NASA Dome

The black hole in galaxy NGC 1277 has a mass of 17 billion suns (for comparison, the black hole at the center of the Milky Way has a mass of about 4 million Suns) and contains an absolutely extraordinary 14% of the total mass of the galaxy it is in. The size of NGC 1277 is all the more astonishing because the surrounding galaxy is very small. This could be the largest supermassive black hole found to date.

The wonderful astrophotographer César Cantú takes amazing pictures of the sky, and his shots of the Sun are truly cool. On Wednesday, August 8, 2012, he took this image of the Sun and a sunspot called Active Region 1524

Celestial phenomenon , October 7, 2009 , Russia By Annenkov Andrey

Summer Solstice, Alaska ::On this, the longest days of the northern year, the sun never sets at the Arctic Circle. It loops around, kissing the northern horizon and casting an amazing orange glow before rising again::

This is a rare meteorological phenomenon called a skypunch. When people see these, they think it's the end of the world. Ice crystals form above the high-altitude cirro-cumulo-stratus clouds, then fall downward, punching a hole in the cloud cover. #Meteorology #Weather #Clouds

What created the Waterfall Nebula? No one knows. The structure seen in the region of NGC 1999 in the Great Orion Molecular Cloud complex is one of the more mysterious structures yet found on the sky.
