So it’s not entirely surprising—though no less interesting—when some of those galaxies are spotted doing unusual tricks. Here are a couple of the latest galactic antics revealed by astronomers using the Keck Telescopes. 2012-04-16T20:05:18+00:00 http://keckobservatory.org/blog/50_years_keck_telescopes http://keckobservatory.org/blog/50_years_keck_telescopes#When:22:22:51Z It was 25 years ago that Hilton Lewis and Allan Honey started working on the Keck telescopes. They and some others are hitting the quarter century milestone and they have a lot to remember and celebrate. 2012-02-14T22:22:51+00:00 http://keckobservatory.org/blog/how_to_count_to_one http://keckobservatory.org/blog/how_to_count_to_one#When:23:24:53Z How many observatories are there on Mauna Kea? The honest answer is 12, or 13, eight or even one. Why so many answers? Because there is a lot more than math involved. 2012-01-12T23:24:53+00:00 http://keckobservatory.org/blog/keeping_keck_telescopes_shiny http://keckobservatory.org/blog/keeping_keck_telescopes_shiny#When:20:50:41Z They are two of the largest telescope mirrors on the planet and they only work if they are bright and shiny. Keeping them that way that at almost 14,000 feet above sea level, while also not disrupting nightly astronomical observations, involves an ongoing dance of men and machines. 2011-11-10T20:50:41+00:00 http://keckobservatory.org/blog/astronomical_myths_facts http://keckobservatory.org/blog/astronomical_myths_facts#When:20:37:48Z So you think you know something about those giant Keck telescopes up on Mauna Kea? Wanna bet? Test your O.I.Q. (that’s Observatory Intelligence Quotient) with this quick true-or-false pop quiz. 2011-10-18T20:37:48+00:00 http://keckobservatory.org/blog/interns_find_opportunities_at_keck_observatory http://keckobservatory.org/blog/interns_find_opportunities_at_keck_observatory#When:19:24:02Z The observatory interns of today are the professional engineers and scientists of tomorrow. Hear from three Keck summer interns about their projects, what they have learned and what Keck and other cutting edge high-tech organizations get from a summertime injection of young intellect 2011-08-12T19:24:02+00:00 http://keckobservatory.org/blog/hawaiis_coldest_steepest_job http://keckobservatory.org/blog/hawaiis_coldest_steepest_job#When:14:00:38Z It’s not as rough as exploring Antarctica with sled dogs, but working near the summit of Mauna Kea has its risks and rewards. Keck Observatory’s Joel Aycock and Joe Gargiulo talk about what life is like when you spend half of it laboring in the rarified air near 14,000 feet and why it’s worth all the weird things thin air does to your brain and body. 2011-07-11T14:00:38+00:00 http://keckobservatory.org/blog/light_sabers_on_mauna_kea http://keckobservatory.org/blog/light_sabers_on_mauna_kea#When:22:41:15Z There are now four laser-toting telescopes on Mauna Kea, leading to some impressive new images and videos. The Keck I telescope is the latest to get a state-of-the-art laser which, when fired alongside the Keck II laser, can lead to images that bear a striking resemblance to scenes from Star Trek. But there is a lot more to these lasers than nice pictures. There’s a lot of gnarly science going on at both ends of those beams. 2011-06-06T22:41:15+00:00 http://keckobservatory.org/blog/i_am_oz_the_great_and_powerful http://keckobservatory.org/blog/i_am_oz_the_great_and_powerful#When:10:19:34Z When the Wizard of Oz roared that line, he was hidden behind a curtain. He knew all too well that he was not particularly great nor very powerful, and wanted no one to find out (a scheme foiled by that heroic terrier Toto). The opposite problem exists at the W. M. Keck Observatory. There is genuinely great cosmic stuff being discovered with the world’s largest, optical and infrared telescopes – so ‘great’ and ‘powerful’ apply – but to many folks it all seems hidden behind a curtain. There is no curtain, of course, as anyone knows if they have poked around the Keck Observatory Visitor Center in Waimea. But to banish even the shadow of any Oz-like shenanigans, here is a quick, easy-to-digest, summary of a few recent bona fide feats of Keck wizardry, including the discovery of the coldest star, the brightest star and a glimpse into the uncharted depths of Jupiter. 2011-05-12T10:19:34+00:00 http://keckobservatory.org/blog/super_luminous_stars_deep_dark_skies_super_moons http://keckobservatory.org/blog/super_luminous_stars_deep_dark_skies_super_moons#When:17:00:15Z Super Stars: The Keck I Telescope played a key role in unraveling the mysteries of one of the brightest supernovas ever discovered. At its peak, supernova 2008am was over 100 billion times brighter than the Sun. It emitted enough energy in one second to satisfy the power needs of the United States for one million times longer than the universe has existed. Dark Skies: Back on Earth the power we use causes a lot of light pollution that blocks our view of the universe. This weekend is your chance to help keep your skies dark through the GLOBE at Night campaign. Super Moon Facts & Fiction: The scientific explanation for the recent Super Moon is simple. But the tall tales and myths that hitch along with the Super Moon are many and varied. Here’s a primer on Super Moons (yes, there is more than one kind). 2011-04-01T17:00:15+00:00
