Explanation: Ghostly in appearance, Abell 39 is a remarkably simple, spherical nebula about five light-years across. Well within our own Milky Way galaxy, the cosmic sphere is roughly 7,000 light-years distant toward the constellation Hercules. Abell 39 is a planetary nebula, formed as a once sun-like star's outer atmosphere was expelled over a period of thousands of years. Still visible, the nebula's central star is evolving into a hot white dwarf. Although faint, the nebula's simple geometry has proven to be a boon to astronomers exploring the chemical abundances and life cycles of stars. In this deep image recorded under dark night skies, very distant background galaxies can be found -- some visible right through the nebula itself.

The Redbull jump will happen tomorrow. Man, that is a long way down.

What is so whacky about all the space pics?
Nothing. They just totally kick ***. You don't have to look if you don't like them.
Edit: Actually, much of what you see. Is completely wacky compared to every day things on this earth.
I like them. So keep em coming
This nebula (IC 1396) image is actually wacky! :laugh2:
Me too Sam. I hadn't seen that picture of Abell 39. Fascinating.
I like them too...just doesn't seem "wacky" like this thread suggests. I wish Sam I am would post a pic of himself. That'd be wacky!
An image of me exists on this board already.
It was just a police mug shot though
I was on a boat! Since when do they take mugshots on boats? :laugh2:
Maybe at some point I will post a better (and bigger) image.
Air-powered urban commuter car by TATA motors. The 'airpod' seats three passengers, using compressed air rather than traditional fuel for a zero-emissions ride.
Huge plume of Saharan dust blowing off western Africa was glimpsed Monday by our Aqua satellite.
This image may not look that spactacular, but it is. Matter of fact, it's quite wacky and very cool.
The discovery of a star with spiral arms in 2011 startled researchers using the Subaru telescope in Hawaii. The star, SAO 206462, is more than four hundred light years from Earth in the constellation Lupus, the wolf. Two spiral arms, acquired by the Subaru Telescope and its HiCIAO instrument, emerge from the gas-rich disk around SAO 206462. This image is the first to show spiral arms in acircumstellar disk --some 14 billion miles across, or about twice the size of Pluto's orbit in our own solar system.
Researchers strongly suspected that new planets might be coalescing inside the disk, which is about twice as wide as the orbit of Pluto. But when they took a closer look at SAO 206462 they found not planets, but arms. Astronomers have seen spiral arms before: they’re commonly found in pinwheel galaxies where hundreds of millions of stars spiral together around a common core. Finding a clear case of spiral arms around an individual star, however, is unprecedented, The arms might be a sign that planets are forming within the disk.
btw, I highly recommend you click on these images. They will pop out in full size and you can see much better detail.
Explanation: It's easy to get lost following the intricate filaments in this detailed mosaic image of faint supernova remnant Simeis 147 (S147). Also cataloged as Sh2-240, it covers nearly 3 degrees or 6 full moons on the sky. That's about 150 light-years at the stellar debris cloud's estimated distance of 3,000 light-years. Anchoring the frame at the right, bright star Elnath (Beta Tauri) is seen towards the boundary of the constellations Taurus and Auriga, almost exactly opposite the galactic center in planet Earth's sky. This sharp composite includes image data taken through a narrow-band filter to highlight emission from hydrogen atoms tracing the shocked, glowing gas. The supernova remnant has an estimated age of about 40,000 years, meaning light from the massive stellar explosion first reached Earth 40,000 years ago. But the expanding remnant is not the only aftermath. The cosmic catastrophe also left behind a spinning neutron star or pulsar, all that remains of the original star's core.
Bourtange Star Fort in Groningen, Netherlands
Scientists using the Spitzer Infrared Space Telescope detected tiny specks of matter, or particles, consisting of stacked buckyballs. They found the particles around a pair of stars called "XXOphiuchi," 6,500 light-years from Eart --enough to fill the equivalent in volume to 10,000 Mount Everests.
#BAFact: When massive stars are born, their UV light and fierce winds carve huge cavities in the surrounding gas.
Many stars are born in vast gas clouds, light years across. If the newborn stars are massive and hot, they can blast out huge amounts of ultraviolet radiation and blow strong super-solar winds. This eats away at the gas and dust in the cloud from the inside out, turning the cloud into more of a soap bubble.
The image below is in the far infrared and shows Barnard 3, one such cloud being dissolved by the intense energy of the star in its center (the one surrounded by the reddish glow). Mind you, this cloud is 250 trillion (250,000,000,000,000) kilometers across!
