'Impossible’ Binary Stars Discovered
ScienceDaily (July 5, 2012) — A team of astronomers have used the United Kingdom Infrared Telescope (UKIRT) on Hawaii to discover four pairs of stars that orbit each other in less than 4 hours. Until now it was thought that such close-in binary stars could not exist. The new discoveries come from the telescope’s Wide Field Camera (WFCAM) Transit Survey, and appear in the journal Monthly Notices of the Royal Astronomical Society.

Hubble Spots a Bright Spark in a Nearby Spiral Galaxy

ScienceDaily (June 9, 2012) — A new image, taken by the NASA/ESA Hubble Space Telescope, shows a detailed view of the spiral arms on one side of the galaxy Messier 99. Messier 99 is a so-called grand design spiral, with long, large and clearly defined spiral arms — giving it a structure somewhat similar to the Milky Way.

Crash of the Titans: Milky Way Is Destined for Head-On Collision With Andromeda Galaxy

ScienceDaily (May 31, 2012) — NASA astronomers can now predict with certainty the next major cosmic event to affect our galaxy, Sun, and solar system: the titanic collision of our Milky Way galaxy with the neighboring Andromeda galaxy.

The Last Transit of Venus in Your Lifetime

(Tuesday, June 5th, 2012)

The transit will begin at around 6:09 p.m. EDT (22:09 GMT) on Tuesday, June 5, and will last roughly seven hours. People located in the mid-Pacific region, where the sun will be high overhead throughout the transit, are particularly lucky because they will be able to witness majority of the event.

Still, others in North America, Europe, Asia and eastern Africa should be able to see at least part of the transit in person.

In North America, the best time to view the transit will be in the afternoon, in the hours before sunset on June 5. In Europe, Africa and Australia, Venus will be traveling across the sun as it rises in the morning on June 6…

Sifting Through Dust Near Orion’s Belt

ScienceDaily (May 2, 2012) — A new image of the region surrounding the reflection nebula Messier 78, just to the north of Orion’s Belt, shows clouds of cosmic dust threaded through the nebula like a string of pearls. The observations, made with the Atacama Pathfinder Experiment (APEX) telescope*, use the heat glow of interstellar dust grains to show astronomers where new stars are being formed.

Growing Up Supermassive: A Black Hole’s Diet of Stars

ScienceDaily (Apr. 2, 2012) — A study led by a University of Utah astrophysicist found a new explanation for the growth of supermassive black holes in the center of most galaxies: they repeatedly capture and swallow single stars from pairs of stars that wander too close.

“I look up at the night sky, and I know that, yes, we are part of this Universe, we are in this Universe, but perhaps more important than both of those facts is that the Universe is in us. When I reflect on that fact, I look up—many people feel small, because they’re small and the Universe is big, but I feel big, because my atoms came from those stars” - Neil deGrasse Tyson

Galaxy Cluster Hidden in Plain View
ScienceDaily (Mar. 6, 2012) — A team of astronomers has discovered the most distant cluster of red galaxies ever observed using FourStar, a new and powerful near-infrared camera on the 6.5m Magellan Baade Telescope. The galaxy cluster is located 10.5 billion light years away in the direction of the constellation Leo. It is made up of 30 galaxies packed closely together, forming the earliest known “galaxy city” in the universe.
