Possible 'Comet of the Century' Blazes Up in New Photos

http://www.livescience.com/37015-comet-ison-photos-gemini-observatory.html

May 30, 2013 - LiveScience.com
A comet that could become one of the brightest ever seen when it flys by the sun this November is already remarkably bright and active, a new set of photos shows.

Comet ISON sports a well-defined tail of dust and gas even though it remains far from the sun, the new images from Hawaii's Gemini North Observatory reveal. But it's still too early to tell if ISON will live up to the "comet of the century" hype, researchers stress.

As Comet C/2012 S1 (ISON) heads closer to Earth, we’re getting a better view of what has been billed by some as the “Comet of the Century.” Astronomers say these new photos from the Gemini North telescope on Mauna Kea, Hawai‘i provide hints of how well this comet might survive one of the closest comet encounters with the Sun ever recorded, on November 28, 2013.

Telescope in Hawaii captures images of comet heading toward Earth

An observatory in Hawaii has captured a series of images of a comet on its way into the inner solar system hinting at coming changes, astronomers say.

The time-sequence images from the Gemini Observatory, spanning early February through May, show remarkable activity on the part of Comet ISON despite its distance from the sun and Earth, they said.

Big Picture: Comet ISON ploughs on toward Sun

May 31, 2013 - BBC News
Comet ISON continues to foreshadow its close pass of the Sun later in the year - Hawaii's Gemini Observatory snapped these images of ISON crossing the sky in early February, March, April and May. It will pass within 1.2m km of the Sun in November, and could be the "comet of the century" if it does not burn up entirely on the way.

Why gamma-ray burst shocked scientists

http://www.cnn.com/2013/05/06/opinion/urry-gamma-ray-burst/index.html

May 6, 2013 - CNN.com
On April 27, NASA's Fermi and Swift satellites detected a strong signal from the brightest gamma-ray burst in decades. Because this was relatively close, it was thousands of times brighter than the typical gamma-ray bursts that are seen by Swift every few days. Scientists are now scrambling to learn more.
...
Thanks to observations made with the Gemini ground-based optical telescope in Hawaii, it quickly became clear that GRB130427A was superbright primarily because it lay only a few billion light years away. Had it been situated in a much more distant galaxy -- as many gamma-ray bursts are -- its signal would have been relatively feeble.

Chile Pins High-Tech Hopes on Heavens

http://online.wsj.com/article/SB10001424127887323628004578457203414317068.html

May 2, 2013 - Wall Street Journal
The desert here, with its pristine skies and bone-dry climate, is luring a bounty of the world's stargazers and raising hopes Chile can reap a boon in research and development and high-tech industry.
Investments in the astronomy sector are well under way and expected to reach nearly $6 billion by the end of this decade, giving northern Chile about 70% of the world's astronomical observatories. Astronomers say the extreme aridness and lack of light pollution there gives them less atmospheric distortion than elsewhere in the world.
"In the last five years, there have been on average 280 to 300 clear nights a year," said Rodrigo Carrasco, an assistant astronomer at the Gemini Observatory in La Serena in northern Chile's Atacama Desert. "That's higher than anywhere else and it's a particularity of the Chilean skies."
