Setting stars reveal planetary secrets

11-05-2007 · European Space Agency (ESA)

Watching the stars set from the surface of the Earth may be a romantic pastime but when a spacecraft does it from orbit, it can reveal hidden details about a planet's atmosphere.

  1. Stellar tiramisu
    07-07-2007 · EurekAlert!
    Looking at the chemical composition of stars that host planets, astronomers have found that while dwarf stars often show iron enrichment on their surface, giant stars do not. The astronomers think that the planetary debris falling onto the outer layer of the star produces a detectable effect in a dwarf star, but this pollution is diluted by the giant star and mixed into its interior.

  2. Star family seen through dusty fog
    03-13-2007 · EurekAlert!
    Images made with ESO's New Technology Telescope at La Silla by a team of German astronomers reveal a rich circular cluster of stars in the inner parts of our Galaxy. Located 30,000 light-years away, this previously unknown closely-packed group of about 100,000 stars is most likely a new globular cluster.

  3. New technology enables astronomers to detect two supermassive black holes in colliding galaxies
    05-17-2007 · EurekAlert!
    Astronomers, including UCR’s Gabriela Canalizo, have used powerful adaptive optics technology at the W.M. Keck Observatory in Hawai‘i to reveal the precise locations and environments of a pair of supermassive black holes at the center of an ongoing collision between two galaxies 300 million light-years away. Each of the black holes resides at the center of a rotating disk of stars and is surrounded by a cloud of young star clusters formed in the merger.

  4. Tears reveal some of their deepest secrets to researchers
    01-19-2007 · EurekAlert!
    It's no secret why we shed tears. But exactly what our tears are made of has remained a mystery to scientists. A new study sheds some light on the complex design of tears. What we think of as tears, scientists call tear film, which is made up of three distinct, microscopic layers.

  6. Astronomers First To Measure Night And Day On Extrasolar Planet
    10-12-2006 · ScienceDaily
    University of Central Florida Astronomy professor Joseph Harrington and University of California at Los Angeles professor Brad M. Hansen and their team have made the first direct observation of distinct day and night temperatures on a planet orbiting another star. UCF Professor Joseph Harrington says that studying planetary atmospheres under such exotic conditions puts terrestrial and solar-system meteorology into a universal context, which aids in our understanding of weather on all planets.

  8. Planets forming in Pleiades star cluster, astronomers report
    11-15-2007 · EurekAlert!
    Rocky terrestrial planets, perhaps like Earth, Mars or Venus, appear to be forming or to have recently formed around a star in the Pleiades ("seven sisters") star cluster, the result of "monster collisions" of planets or planetary embryos.Astronomers using the Gemini Observatory in Hawaii and the Spitzer Space Telescope report their findings in an upcoming issue of the Astrophysical Journal, the premier journal in astronomy.

  9. New type of massive stellar death
    12-20-2006 · EurekAlert!
    So far we have thought that the signature of the death of a massive star was an energetic explosion called a "supernova." New observations show that this is not always the case. On the contrary, a team led by Danish researchers has now discovered that some massive stars die by collapsing into a black hole returning very little material into the interstellar medium. The new discovery is published in Nature.

  10. Study sheds new light on early star formation in the universe
    09-13-2007 · EurekAlert!
    A groundbreaking study has provided new insight into the way the first stars were formed at the start of the universe, some 13 billion years ago. Cosmologists from Durham University, publishing their results in the prestigious international academic journal, Science, suggest that the formation of the first stars depends crucially on the nature of "dark matter," the strange material that makes up most of the mass in the universe.
