Veil Nebula Supernova Remnant

via NASA Hubble Space Telescope has unveiled in stunning detail a small section of the expanding remains of a massive star that exploded about 8,000 years ago.

Called the Veil Nebula, the debris is one of the best-known supernova remnants, deriving its name from its delicate, draped filamentary structures. The entire nebula is 110 light-years across, covering six full moons on the sky as seen from Earth, and resides about 2,100 light-years away in the constellation Cygnus, the Swan.

This view is a mosaic of six Hubble pictures of a small area roughly two light-years across, covering only a tiny fraction of the nebula’s vast structure.

This close-up look unveils wisps of gas, which are all that remain of what was once a star 20 times more massive than our sun. The fast-moving blast wave from the ancient explosion is plowing into a wall of cool, denser interstellar gas, emitting light. The nebula lies along the edge of a large bubble of low-density gas that was blown into space by the dying star prior to its self-detonation.

Charting the slow death of the Universe

Paris (SPX) Aug 12, 2015 The study, which is part of the Galaxy And Mass Assembly (GAMA) project, the largest multi-wavelength survey ever put together, involved many of the world’s most powerful telescopes [1]. “We used as many space and ground-based telescopes as we could get our hands on to measure the energy output of over 200 000 galaxies across as broad a wavelength range as possible,” says Simon Driver ICRA Full article

Callisto, Jupiter’s heavily-cratered Galilean moon that’s around 99% as large as Mercury but only a third as massive, bears a striking resemblance to that planet.

So it turns out, Pluto is red.

What color is Pluto? If you search for the dwarf planet on Google, images suggest that it’s a sort of steely blue or gray color. But now, NASA’s New Horizons spacecraft is closing in on it, and has learned Mars isn’t the only red planet in our solar system. But the reason it’s red couldn’t be more different from Mars.
