Some cosmic beauty for a lovely Sunday. :-)
 
LL Orionis: When Cosmic Winds Collide

What created this great arc in space? This arcing, graceful structure is actually a bow shock about half a light-year across, created as the wind from young star LL Orionis collides with the Orion Nebula flow. Adrift in Orion's stellar nursery and still in its formative years, variable star LL Orionis produces a wind more energetic than the wind from our own middle-aged sun. As the fast stellar wind runs into slow moving gas a shock front is formed, analogous to the bow wave of a boat moving through water or a plane traveling at supersonic speed. The slower gas is flowing away from the Orion Nebula's hot central star cluster, the Trapezium, located off the lower right hand edge of the picture. In three dimensions, LL Ori's wrap-around shock front is shaped like a bowl that appears brightest when viewed along the "bottom" edge. The complex stellar nursery in Orion shows a myriad of similar fluid shapes associated with star formation, including the bow shock surrounding a faint star at the upper right. Part of a mosaic covering the Great Nebula in Orion, this composite color image was recorded in 1995 by the Hubble Space Telescope.

Celestial event for the weekend!
 
Closer to Earth this week than at any time in the last decade, Mars will be in opposition, offering a good show. Ten years ago, at the closest approach in a century, I wrote “Mars Opposition,” one of the most unusual alien invasion stories you’ll ever read! You’ll find it in Insistence of Vision.

Get ready space enthusiasts; it’s going to be a good weekend to look to the sky!

Boosting the signal - this looks like a good project
 
And I have a request for everyone who has been following the women in sf project. Rather than explain it all again here, I'm linking to the site. You can respond here if you want:

This is pretty amazing!
 
Inside a Daya Bay Antineutrino Detector

Why is there more matter than antimatter in the Universe? To better understand this facet of basic physics, energy departments in China and the USA led in the creation of the Daya Bay Reactor Neutrino Experiment. Located under thick rock about 50 kilometers northeast of Hong Kong, China, eight Daya Bay detectors monitor antineutrinos emitted by six nearby nuclear reactors. Featured here, a camera looks along one of the Daya Bay detectors, imaging photon sensors that pick up faint light emitted by antineutrinos interacting with fluids in the detector. Early results indicate an unexpectedly high rate of one type of antineutrino changing into another, a rate which, if confirmed, could imply the existence of a previously undetected type of neutrino as well as impact humanity's comprehension of fundamental particle reactions that occurred within the first few seconds of the Big Bang.

Frosted dunes on Mars! I've never seen this before.
 
Frosted Dunes on Mars

In this image taken by the High Resolution Imaging Science Experiment (HiRISE) aboard the Mars Reconnaissance Orbiter (MRO) you can see frosted dunes on Mars in late winter. They are getting more and more sunlight and because of that start to defrost their cover of carbon dioxide. Read more on the seasons of Mars here:

I think my pocket universe may be a disorganized dwarf galaxy...
 
This disorganized dwarf galaxy seen by our Hubble Space Telescope is located about 11 million light-years away. Lacking a distinctive structure or shape, irregular dwarf galaxies are often chaotic in appearance. Find out more: http://go.nasa.gov/236tqw6
