Window Into Europa’s Ocean Opened By Astronomers
2013-03-05 10:28:13

W. M. Keck Observatory With data collected from the mighty W. M. Keck Observatory, California Institute of Technology (Caltech) astronomer Mike Brown – known as the Pluto killer for discovering a Kuiper-belt object that led to the demotion of Pluto from planetary status – and Kevin Hand from the Jet Propulsion Laboratory (JPL) have found the strongest evidence yet that salty water from the vast liquid ocean beneath Europa´s frozen exterior actually makes its way to the...

Keck Week 2013 Celebrates W.M. Keck Observatory's 20th Anniversary
2012-12-12 09:52:03

W. M. Keck Observatory This Spring, the W. M. Keck Observatory is throwing a weeklong party called Keck Week 2013, to celebrate the observatory´s first twenty years of high-impact, game-changing astronomical discoveries from the venerable twin-domes on the summit of Mauna Kea, Hawaii. The festivities will take place in several Kohala Coast resort venues as well as in the town of Kamuela and will mark a distinctive confluence of the brightest minds in astronomy alongside our...

Astronomers Take Starburst Galaxy Census
2012-12-04 13:02:44

Lee Rannals for redOrbit.com - Your Universe Online Astronomers have taken a census of hundreds of previously unseen starburst galaxies, revealing high star-formation rates across the Universe. The team used the European Space Agency's Herschel space observatory and ground-based W. M. Keck Observatory to make the observation. Starburst galaxies give birth to hundreds of solar masses' worth of stars every year, while galaxies like our Milky Way produce only one Sun-like star per year....

Astronomers Monitor Volcanic Activity On Jupiter’s Moon Io From Earth
2012-10-17 11:01:21

Lawrence LeBlond for redOrbit.com - Your Universe Online Watching active volcanic eruptions should be done so from a safe distance. Observing active eruptions here on Earth can be easily accomplished from the comfort of your home with proper equipment. But observing an Earthen volcanic eruption from home is nothing when compared to what a group of California researchers have been privy to. Using an ingenious combination of ground-based telescopic surveys and archival data, the Golden...

Ancient Spiral Galaxy Observed By Astronomers
2012-07-18 12:42:04

Lee Rannals for redOrbit.com - Your Universe Online A new discovery may help astronomers peer back in time to when spiral galaxies first began to take their shape. Scientists wrote in the journal Nature that they had found a surprising ancient spiral galaxy known as BX442. The galaxy was found by astronomers who first surveyed 300 distant galaxies using the Hubble Space Telescope. They followed up and confirmed it using detailed observations and analyzes from the W.M. Keck...

Astrophysicists Use Three-Telescope Interferometry To Observe How Black Holes Are Fueled
2012-05-18 03:45:33

By combining the light of three powerful infrared telescopes, an international research team has observed the active accretion phase of a supermassive black hole in the center of a galaxy tens of millions of light years away, a method that has yielded an unprecedented amount of data for such observations. The resolution at which they were able to observe this highly luminescent active galactic nucleus (AGN) has given them direct confirmation of how mass accretes onto black holes in centers of...

UCLA's "Time Machine" To Study Distant Galaxies
2012-04-13 10:28:20

[ Watch the Video ] A team of researchers at the University of California, Los Angeles (UCLA) are building an advanced scientific instrument unlike any other ever built before, with the aim to study some of the oldest galaxies in the universe. The five-ton spectrometer, known as MOSFIRE (Multi-Object Spectrometer for Infra-Red Exploration), has been installed in the Keck I Telescope at the WM Keck Observatory in Hawaii where, once fully operational, it will receive infrared light that...

An international team of scientists led by Carnegie's Guillem Anglada-Escudé and Paul Butler has discovered a potentially habitable super-Earth orbiting a nearby star. The star is a member of a triple star system and has a different makeup than our Sun, being relatively lacking in metallic elements. This discovery demonstrates that habitable planets could form in a greater variety of environments than previously believed. Their work will be published by the Astrophysical Journal...

Dwarf 'Satellite Galaxy' Detected 10 Billion Light Years Away
2012-01-18 14:48:08

An astronomer has discovered a faint "satellite galaxy" that is the lowest-mass object ever detected 10 billion light years away. Finding this dwarf galaxy at such a long distance away may be able to help astronomers find similar objects and confirm or reject theories about the structure of the universe. University of California physics professor Chris Fassnacht said in a statement that theory predicts that galaxies should be surrounded by halos of smaller, satellite blobs of mass....

Astronomers Used Old Hubble Data To Confirm Extrasolar Planets
2011-10-06 12:47:47

NASA said on Thursday that astronomers have found evidence for two extrasolar planets using Hubble Space Telescope data from 1998. Using old Hubble images gives astronomers an invaluable time machine for comparing earlier planet orbital motion data to more recent observations, according to the space agency. Star HR8799 has four giant planets orbiting around it, three of which were discovered in 2007 and 2008 in near-infrared ground-based images taken by astronomers at W.M. Keck...

Interferometry -- Interferometry is the applied science of combining two or more input points of a data type, such as optical, and combine these data to form a greater picture based on the combination of the two sources. This technique is the basis for proposed radio telescope arrays, which spread out upon a wide area of hundreds of miles, can together produce a picture with resolution similar or equivalent to a single telescope with the diameter of the combined spread of telescopes. The...

Keck Observatory -- From a remote outpost on the summit of Hawaii's dormant Mauna Kea volcano, astronomers at the W.M. Keck Observatory probe the deepest regions of the Universe with unprecedented power and precision. Their instruments are the twin Keck Telescopes, the world's largest optical and and infrared telescopes. Each stands eight stories tall and weighs 300 tons, yet operates with nanometer precision. At the heart of each Keck Telescope is a revolutionary primary mirror. Ten...

Mauna Kea Observatories -- Hawaii is Earth's connecting point to the rest of the Universe. The summit of Mauna Kea on the Island of Hawaii hosts the world's largest astronomical observatory, with telescopes operated by astronomers from eleven countries. The combined light-gathering power of the telescopes on Mauna Kea is fifteen times greater than that of the Palomar telescope in California -- for many years the world's largest -- and sixty times greater than that of the Hubble Space...
