The NASA/ESA Hubble Space Telescope imaged three magnificent sections of the Veil Nebula in 1997. Now, a stunning new set of images from Hubble’s Wide Field Camera 3 capture these scattered stellar remains in spectacular new detail and reveal its expansion over the last years.

Deriving its name from its delicate, draped filamentary structures, the beautiful Veil Nebula is one of the best-known supernova remnants. It formed from the violent death of a star twenty times the mass of the Sun that exploded about 8000 years ago. Located roughly 2100 light-years from Earth in the constellation of Cygnus (The Swan), this brightly coloured cloud of glowing debris spans approximately 110 light-years.

More seriously:

The Hubble continues to amaze. I was born in 1970 and it has had the most impact on me and my imagination and appreciation of space than any other 'space program' related endeavor during my lifetime, and that includes the Shuttles and the three Space Camps that I attended as a teenager.

this is the one that gets me, every time. . .


The Hubble Deep Field: It covers an area about 2.6 arcminutes on a side, about one 24-millionth of the whole sky, which is equivalent in angular size to a tennis ball at a distance of 100 metres. Virtually every object which appears in this image is a galaxy. Even the red specs which appear as dust, are galaxies.

The nitrogen in our DNA, the calcium in our teeth, the iron in our blood, the carbon in our apple pies were made in the interiors of collapsing stars. We are made of starstuff.

We are a way for the cosmos to know itself.

I cannot recommend this series strongly enough.

As a sentient supposedly intelligent species we don't do it justice do we?

Too bad Sagan didn't get to see these pix from the Hubble.

Relax, Paul, we're sharing from different seas. It's all good :)
