Explanation: Is this really the famous Pleiades star cluster? Known for its iconic blue stars, the Pleiades is shown here in infrared light where the surrounding dust outshines the stars. Here three infrared colors have been mapped into visual colors (R=24, G=12, B=4.6 microns). The base images were taken by NASA's orbiting Wide Field Infrared Survey Explorer (WISE) spacecraft. Cataloged as M45 and nicknamed the Seven Sisters, the Pleiades star cluster is by chance situated in a passing dust cloud. The light and winds from the massive Pleiades stars preferentially repel smaller dust particles, causing the dust to become stratified into filaments, as seen. The featured image spans about 20 light years at the distance of the Pleiades, which lies about 450 light years distant toward the constellation of the Bull (Taurus).

Yikes! My Subaru Outback has gone rainbow!

Great image, actually. Would make a nice “wallpaper”.

Haven’t seen much coming from the web telescope.. for what we paid I would expect Stellar images (get it? πŸ˜„πŸ™„) everyday.

Cross between a swan and a peacock . . . I see the arched neck at upper left. Beautiful.

I knew these new glasses sounded too good to be true

“...The light and winds from the massive Pleiades stars
preferentially repel smaller dust particles...”
-
Statements like this are puzzling to me.

“Wind”?
In space?

“Repel?”
Gravity (mass) attracts.
What force is there that “repels”?

Gravity is not the only force. Other things have energy that has an outward force like light, alpha particles, neutrons, gamma rays, etc. These impact dust and impart energy in a direction. Gravity becomes dominant in black holes when even light energy cannot escape. These are all lower than black hole gravity events where there is plenty of energy and mass outflow (energy and mass have the relationship e=mc2).
