Picture of the Week
Looking towards the constellation of Triangulum (The Triangle), in the northern sky, lies the galaxy pair MRK 1034. The two very similar galaxies, named PGC 9074 and PGC 9071, are close enough to one another to be bound together by gravity, although no gravitational disturbance can yet be seen in the image. These objects are probably only just beginning to interact gravitationally. Both are spiral galaxies, and are presented to our eyes face-on, so we are able to appreciate their distinctive shapes. On the left of the image, spiral galaxy PGC 9074 shows a bright bulge and two spiral arms tightly wound around the nucleus, features which have led scientists to classify it as a type Sa galaxy. Close by, PGC 9071 — a type Sb galaxy — although very similar and almost the same size as its neighbour, has a fainter bulge and a slightly different structure to its arms: their coils are further apart.

Universal Big Questions ?
Earlier this month, NASA announced the discovery of bacteria living in arsenic in a California lake. Now they have uncovered ET amino-acids in meteorite fragments that landed in northern Sudan. The meteorite was a fragment of a parent asteroid measuring 13-feet-wide (4m), and weighing 59-tons. Scientists were given the first opportunity to observe a celestial object before it entered our atmosphere in October 2008 after a collision about 15 million years ago sent the asteroid closer to Earth. During expeditions in the Sudanese desert, scientists later recovered nearly 600 meteorite fragments from the meteor shower. Just a few weeks ago, the bacteria living in arsenic finding presented by NASA, was preceded by media speculation about the possibility that the space agency would announce that it had found life in outer space.

The Planet's Most Powerful Digital Camera Captures Its First Images of the Universe - Megan Garber
The device could help astronomers figure out why the expansion of the universe is accelerating. Zoomed-in image from the Dark Energy Camera of the center of the globular star cluster 47 Tucanae, which lies about 17,000 light years from Earth (Dark Energy Survey Collaboration) The Dark Energy Camera is the world's most powerful digital camera.

The Universe is Alive – Starts With A Bang
“Night, when words fade and things come alive. When the destructive analysis of day is done, and all that is truly important becomes whole and sound again.” -Antoine de Saint-Exupery When you look out into the Universe, what is it that you typically think of?
Speed of the Milky Way in Space
"The Milky Way and the Andromeda galaxy are approaching each other with a speed of 300,000 miles per hour." or 130 km/s As we all know, a galaxy is a massive ensemble of hundreds of millions of stars. The galaxy where we live in today is called the Milky Way. The name itself came from the ancient Greek galaxies kyklos, or ring of milk, due to its faint milky appearance.

I like the planck length (as it relates to two photons of light traveling across the universe, and neither being delayed--smooth). by Mar 25
I love this and showed it to my dad and he thought it was pretty neat. I love the pillars of creations and horsehead nebula. by Mar 24
