Astronomy Photo of the Day: 7/26/14 - NGC 253
Meet NGC 253; a beautiful island galaxy located in the constellation of Sculptor, some 10 million light-years from Earth. As you can see from this nearly-edge on vantage point, its beauty is rivaled only by its sheer dustiness. Other than the dust pervading the galaxy’s spiral arms, tendrils of dense collections of dust extend from its tilted galactic disk and beyond. This extra material has spawned an impressive collection of stars, with the combined light making the galaxy one of the brightest galaxies known to man. Also helping make this galaxy so spectacularly bright and impressive is the ionization these stars induce on the galaxy’s extensive gas reserves.
NGC 253 — also known as the Silver Dollar Galaxy (because of the way it looks when viewed through a moderately powerful telescope) — spans some 70,000 light-years across. As such, it is the largest member of the Sculptor Group of Galaxies, which is the closest galaxy group to our own local group.

Can you solve this puzzle?
"I’m going to give you a three number sequence, and I have a rule in mind that these numbers obey. I want you to figure out what that rule is. The way you can get information is by proposing your own set of three numbers, to which I will either say ‘yes that follows my rule’ or ‘no that doesn’t follow my rule.’ and then you can tell me what you think the rule is. Here are the numbers… 2, 4, 8."
No, the answer doesn’t have anything to do with 2.

Imagining a Holographic Universe:
One very colorful idea says that the universe might be nothing more than an extremely detailed hologram, but why do some scientist think this is the case?

Astronomy Photo of the Day: 7/25/14 - The Whirlpool Galaxy As You’ve Never Seen it Before
The Whirlpool galaxy (also known as Messier 51) is one of the most instantly recognizable galaxies known to man, and for good reason too. I mean, just look at it. It has all of the makings of a spectacular sight, with its glorious, brightly-colored spiral arms, its big , accentuated central core, and the red patches that signify newly-formed stars.

It’s a fact that given our growing population and the overexploitation of non-renewable resources, we’re heading toward a breaking point, but when? http://bit.ly/1rOu4ff
Astronomy Photo of the Day (APotD): 7/24/14 - Centaurus A
Thanks to the combined work of Hubble’s sensitive Advanced Camera for Surveys and its Wide Field Camera 3, astronomers have seen a stunning glimpse into the mechanism powering the huge halos that surround galaxies. This instance, the galaxy dubbed Centaurus A (NGC 5128), has proven itself to be very fascinating.
Astronomers have learned that the halo is much larger than originally expected, with them mapping approximately 450,000 light-years of its length (a distance that exceeds the size of our galaxy about 25 times over) and some 295,000 light-years of its width. To put it in another way, this huge region hogs up a full 4 degrees of our sky (or about 8 times more space that the moon takes when its full).
