Giant planets do not come as lonely hearts

02-14-2008 · EurekAlert!

Scaled versions of Jupiter and Saturn orbiting a star 5000 light-years away, half as massive as the sun, have been revealed from an effort involving a world-wide net of telescopes, including the UK's Liverpool Telescope on the Canary Islands. This marks the first discovery of another system of planets that has striking similarities with our solar system.

  1. Far-out findings -- New analysis suggests planets were formed from a giant mix
    12-14-2006 · EurekAlert!
    Our Solar System may have been created in a gigantic mixing process far more extensive than previously imagined, according to research published today.The findings, reported in the journal Science, come from the first analysis of dust fragments from Comet Wild-2, captured by NASA's Stardust spacecraft and brought to Earth in January 2006.

  3. Enceladus geysers mask the length of Saturn's day
    03-22-2007 · European Space Agency (ESA)
    In a David and Goliath story of Saturnian proportions, the little moon Enceladus is weighing down giant Saturn's magnetic field so much that the field is rotating slower than the planet. This phenomenon makes it nearly impossible to measure the length of the Saturn day using techniques that work at the other giant planets.

  4. Planet orbiting a giant red star discovered with hobby-eberly telescope
    08-02-2007 · EurekAlert!
    A planet orbiting a giant red star has been discovered by an astronomy team led by Penn State's Alex Wolszczan, who in 1992 discovered the first planets ever found outside our solar system. The new discovery is helping astronomers to understand what will happen to the planets in our solar system when our Sun becomes a red-giant star, expanding so much that its surface will reach as far as Earth's orbit.

  5. NASA scientists detect spectrum of planets orbiting other stars
    02-22-2007 · EurekAlert!
    For the first time, scientists at Goddard have obtained a spectrum, or molecular fingerprint, of a planet orbiting another star. Using spectroscopy, scientists were able to identify silicon dust in clouds on a gas-giant planet called HD 209458b. That planet is located 150 light years from Earth.

  6. More evidence for new species hidden in plain sight
    12-20-2007 · EurekAlert!
    Two articles published today in the online open access journals BMC Evolutionary Biology and BMC Biology provide further evidence that we have hugely underestimated the number of species with which we share our planet. Today sophisticated genetic techniques mean that superficially identical animals previously classed as members of a single species, including the frogs and giraffes in these studies, could in fact come from several distinct 'cryptic' species.

  7. Day and night temps measured on an extrasolar planet
    10-12-2006 · EurekAlert!
    For the first time, astronomers have measured the day and night temperatures of a planet outside our solar system. The team found that a giant Jupiter-like gas planet orbiting very close to its star is blisteringly hot on one side, and frigid on the other.

  8. Are one-third of costly implanted heart devices unnecessary? New study suggests yes
    01-03-2007 · EurekAlert!
    This year, tens of thousands of heart patients will have high-tech devices implanted in their chests. Called ICDs or implantable cardioverter defibrillators, the expensive devices are designed to shock damaged hearts back into rhythm and save patients from sudden cardiac death. But a new study finds that while many of these patients will benefit from their ICDs, a large number won't -- and a simple heart-rhythm test can tell who's who.

  9. Researchers discover 'sticky' proteins fuse adult stem cells to cardiac muscle, repairing hearts
    02-15-2007 · EurekAlert!
    Cardiologists are increasingly using adult stem cells in clinical trials to repair hearts following heart attacks, but no one has understood how the therapy actually works. Now, in animal experiments, researchers at the University of Texas M. D. Anderson Cancer Center have deconstructed the process, describing how the stem cells fuse with heart muscle cells to create new cells that repopulate the ailing organ.

  10. Cigarette smoke, alcohol damage hearts worse as combo
    11-21-2007 · EurekAlert!
    A new study shows that taking in smoky air and drinking alcohol basically nullify any potential heart benefit from drinking alcohol by itself. Researchers at the University of Alabama at Birmingham found that mice exposed to smoky air and fed a liquid diet containing ethanol, the intoxicating ingredient in alcohol, had a 4.7-fold increase in artery lesions, a key sign of advancing heart disease. The study appears in Free Radical Biology & Medicine.
