In ancient stories, and even some newer ones, the appearance of a comet or any heavenly object could symbolize a God's displeasure and even mean a sure failure in battle for one side.   Tel Aviv University researchers say comets could be even more relevant than mythology suggests; they might have actually provided the elements for the emergence of life on our planet.
The farthest we have 'seen' in space just got a little farther away, thanks to ESO's Very Large Telescope and GRB (Gamma Ray Burst) 090423.

VLT has shown that a faint gamma-ray burst detected last Thursday is the signature of the explosion of the earliest, most distant known object in the Universe (a redshift of 8.2). The explosion apparently took place more than 13 billion years ago, only about 600 million years after the Big Bang.
Back on a frozen pre-Inaugeration Day, I picked up a hitchhiker on US295N. We exchanged the usual banter ("Got any guns? No? Great!").  He wasn't a local, just in town to help assemble bandstands in DC and visiting a friend in Baltimore.  He had three reasons for hitching that cold wintry day: his car had died, he had no money, and it made him feel like he was 17 again.

The strangest part was that he started talking about recent lack of sunspots, as seen by a NASA satellite mission and reported on

Now, what are the odds that an itinerant hitchhiker whose hobby is space weather would happen to get picked up by a solar physicist who worked with the very satellite he'd just read about?
The Hubble Space Telescope turned 19 today.  On this date in 1990, Hubble was launched by the Space Shuttle Discovery (STS-31).

A process called ‘dark gulping’ may solve the mystery of the how supermassive black holes were able to form when the Universe was less than a billion years old.

Dr Curtis Saxton will be presenting the study at the European Week of Astronomy and Space Science at the University of Hertfordshire in Hatfield.
Using information from a suite of telescopes, astronomers have discovered a mysterious, giant object that existed at a time when the universe was only about 800 million years old. Objects such as this one are dubbed extended Lyman-Alpha blobs; they are huge bodies of gas that may be precursors to galaxies. This blob was named Himiko for a legendary, mysterious Japanese queen. It stretches for 55 thousand light years, a record for that early point in time. That length is comparable to the radius of the Milky Way's disk. 
An international team of astronomers has used the world's biggest radio telescope to look deep into the brightest galaxies that NASA's Fermi Gamma-ray Space Telescope can see. The study solidifies the link between an active galaxy's gamma-ray emissions and its powerful radio-emitting jets. 

"Now we know for sure that the fastest, most compact, and brightest jets we see with radio telescopes are the ones that are able to kick light up to the highest energies," said Yuri Kovalev, a team member at the Max Planck Institute for Radio Astronomy in Bonn, Germany.
A new study reveals that asteroid surfaces age and redden much faster than previously thought — in less than a million years, the blink of an eye for an asteroid.  The solar wind is the likely culprit in very rapid space weathering, they say, and this knowledge will help astronomers relate the appearance of an asteroid to its actual history and identify any after effects of a catastrophic impact with another asteroid.
Waves from Daphnis

Undulations mark both sides of the path of Saturn's moon Daphnis through the A ring. 

Daphnis may be small at only 8 kilometers (5 miles) across, but the moon's gravity is great enough, and the Keeler gap in which it resides is narrow enough, so that the perturbed particles create the wavelike patterns seen here. 
"Kepler is like Field of Dreams meets Cosmos" says Padi Boyd, a scientist with the Kepler planet-hunting mission. This set the stage for an enjoyable short interview. Earlier I wrote why Kepler is awesomeness squared, and now we look at how the motivation of the people involved leads to better science success.

Kepler was conceived, proposed, and lead by Bill Borucki. It is NASA Discovery mission #10, designed to be low cost and focused towards one task. For Kepler, that's planet-hunting.
