Hubble Captures Sparkling ‘Jewel Box’ Star Cluster

From Wired Science:

This stunning image of the Kappis Crucis Cluster, nicknamed the “Jewel Box,” was one of the last gifts from a retiring camera on the Hubble Space Telescope.

Just before NASA brought the Wide Field Planetary Camera 2 back to Earth in mid-2009, it snapped this photo of the core of the NGC 4755 star cluster, the first comprehensive image of an open galactic cluster taken in multiple wavelengths. Using seven different filters, Hubble captured the Jewel Box cluster in far ultraviolet to near-infrared light. The different colors of the stars — from pale blue to bright ruby red — result from their differing intensities at various ultraviolet wavelengths.

5 Frightening (But True) Space Stories

The First Seven Astronauts

From Discover Magazine:

There's nothing like a good horror story in space*. I grew up watching Sigourney Weaver outsmart xenomorphs in her underwear and subsequently spent a little too much time reading the likes of Stephen King's "I am the Doorway," H.P. Lovecraft's "In the Walls of Eryx" and John Steakley's "Armor."

As a result, it's hard for me to read about space exploration without thinking of about its darker possibilities -- and I don't just mean aliens and distant Hell worlds. Leaving Earth's atmosphere is a dangerous endeavor and, major tragedies aside, there have been a number of smaller terrifying, grotesque and absurd episodes to come out of it. So if you'll allow me to serve as your cosmic Crypt Keeper for a few minutes, I thought I'd run though a few of the ones that get under my skin.

Blast From The Past: Most Distant Stellar Object Gives Clues About Early Universe

Gamma-ray bursts longer than two seconds are caused by the detonation of a massive star at the end of its life. Jets of particles and gamma radiation are emitted in opposite directions from the stellar core as the star collapses. This animation shows what a gamma-ray burst might look like up close.

From Science Daily:

Science Daily (Oct. 29, 2009) — Astronomers using the National Science Foundation's Very Large Array (VLA) radio telescope have gained tantalizing insights into the nature of the most distant object ever observed in the Universe -- a gigantic stellar explosion known as a Gamma Ray Burst (GRB).

The explosion was detected on April 23 by NASA's Swift satellite, and scientists soon realized that it was more than 13 billion light-years from Earth. It represents an event that occurred 630 million years after the Big Bang, when the Universe was only four percent of its current age of 13.7 billion years.

Why We Carve Pumpkins, Not Turnips

The United States' major pumpkin states produce over one billion pounds worth of pumpkins annually.

From Live Science:

Big orange veggies are pretty strange as far as holiday symbols go, but there are actual historical reasons that we carve pumpkins every Halloween.

Like Halloween itself, the display and carving of pumpkins – from the lanterns placed inside to the scary faces we pick – has pagan origins that morphed with the passage of time as well as the crossing of an ocean.

The modern traditions of Halloween have roots in a Celtic holiday called Samhain, which was celebrated throughout Western Europe (but especially Ireland) every Oct. 31 to mark the end of the summer and the final harvest.

From Science Daily:

Science Daily (Oct. 28, 2009) — Bad drivers may in part have their genes to blame, suggests a new study by UC Irvine neuroscientists.

People with a particular gene variant performed more than 20 percent worse on a driving test than people without it -- and a follow-up test a few days later yielded similar results. About 30 percent of Americans have the variant.

"These people make more errors from the get-go, and they forget more of what they learned after time away," said Dr. Steven Cramer, neurology associate professor and senior author of the study published recently in the journal Cerebral Cortex.
