THANKS, MICHEL!  I do love NASA website, can get lost there for a long time. 

 I also love what you all call "Eye candy" photos from outer space, and made sort of a border of such photos, all around my dining room, matted and framed them after i hit print, right off the net.  works out great, cuz my guy is regular astronomer wanna be, and i like the art.

 

Photos like these adorn my walls:  (cloud that gives birth to stars......doesn't it look like a magic duck from across a room?)

okay, stand way back, stand up, take a few steps back, and kinda squint your eyes, see the duck? ha ha.

From theDaily What   Lights Out: Landscape photographer Terje Sorgjerd (previously) scaled Pico del Teide, Spain´s highest elevation, to capture footage of the Milky Way atop “one of the best places in the world to photograph the stars.”

WOW!

I just checked those pictures, JM.

They are fantastic!

Sunspot Loops in Ultraviolet

Explanation: It was a quiet day on the Sun. The above image shows, however, that even during off days the Sun's surface is a busy place. Shown in ultraviolet light, the relatively cool dark regions have temperatures of thousands of degrees Celsius. Large sunspot group AR 9169 from the last solar cycle is visible as the bright area near the horizon. The bright glowing gas flowing around the sunspots has a temperature of over one million degrees Celsius. The reason for the high temperatures is unknown but thought to be related to the rapidly changing magnetic field loops that channel solar plasma. Large sunspot group AR 9169 moved across the Sun during 2000 September and decayed in a few weeks.

Echoes from the Depths of a Red Giant Star

Explanation: A journey to the center of a red giant star is very firmly in the realm of science fiction. But the science of asteroseismology can explore the conditions there. The technique is to time the small variations in a star's brightness measured by the planet hunting Kepler spacecraft. Regular variations indicate stellar oscillations, analogous to sound waves, that compress and decompress the gas causing brightness changes. As recently discovered in red giant stars, some of the oscillations detected have periods that would cause them to penetrate to the stellar core. In that extreme environment they actually become more intense and can return to the surface. These echoes from the red giant's core are illustrated in this frame from a computer generated animation. Remarkably, the periods measured for the oscillations can even indicate how and where the red giant star's energy production, by hydrogen or helium fusion, is taking place.

Here's a short history of everything.

It is very cool, reminds me of a time many years ago. =)

Will post to general videos then. It's gorgeous, isn't it?
Comment by Michel on April 5, 2011 at 3:21pm

@A - This is really cool eye-candy! This needs to be added to the Videos.

@doone - Anybody can hide in these fields of clumpyness.
