APOD: 2011 September 4 - In the Shadow of Saturn

My astronomy professor showed us this pic and told us that the little little dot that is seen behind the lower left hand part of the outermost ring is actually the Earth!  It’s really hard to see, but it’s there!

Outside In

We all dream of having the ability to fly. Unlike most people in earlier generations, people living now have dreams of flying in space. Outside In plays your dreams right before your eyes. You’ll soar past our nearby worlds and see for yourself what these extraordinary places look like up close. It’s not imaginary; this film is created entirely from real images transmitted to Earth from our spacecraft. We built these machines to extend our knowledge beyond our own world. Outside In makes you part of our species’ extraordinary extraterrestrial journeys.

I love space so much.  It’s absolutely fascinating, the fact that there are these large bodies miles upon miles away from the Earth, that these bodies have their own special composition and satellites.

NASA’s Chandra Finds Nearest Pair of Supermassive Black Holes |
Astronomers using NASA’s Chandra X-ray Observatory discovered the first pair of supermassive black holes in a spiral galaxy similar to the Milky Way. Approximately 160 million light years from Earth, the pair is the nearest known such phenomenon.
 
The black holes are located near the center of the spiral galaxy NGC 3393. Separated by only 490 light years, the black holes are likely the remnant of a merger of two galaxies of unequal mass a billion or more years ago.
“If this galaxy wasn’t so close, we’d have no chance of separating the two black holes the way we have,” said Pepi Fabbiano of the Harvard-Smithsonian Center for Astrophysics (CfA) in Cambridge, Mass., who led the study that appears in this week’s online issue of the journal Nature. “Since this galaxy was right under our noses by cosmic standards, it makes us wonder how many of these black hole pairs we’ve been missing.” continue reading

ODDBALL EXOPLANET IS DARKER THAN COAL
An alien world reflects less than one percent of the starlight that falls on it, making it the blackest exoplanet known.
The strange world, TrES-2b, is a gas giant the size of Jupiter, rather than a solid, rocky body like Earth or Mars, astronomers said.
It closely orbits the star GSC 03549-02811, located about 750 light years away in the direction of the constellation of Draco the Dragon.
“TrES-2b is considerably less reflective than black acrylic paint, so it’s truly an alien world,” David Kipping of the Harvard-Smithsonian Center for Astrophysics said in a press release issued by Britain’s Royal Astronomical Society (RAS).
