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.

- Watching How Planets Form: Anatomy Of A Planet-forming Disc Around A Star More Massive Than The Sun
09-30-2006 · ScienceDaily
With the VISIR instrument on ESO's Very Large Telescope, astronomers have mapped the disc around a star more massive than the sun. The very extended and flared disc most likely contains enough gas and dust to spawn planets. It provides the rare opportunity to witness the conditions prevailing prior to or during planet formation.

Astronomers at the University of Rochester have discovered five Earth-oceans' worth of water that has recently fallen into the planet-forming region around an extremely young, developing star.Dan Watson of the University of Rochester believes he is the first to see a short-lived stage of protoplanetary disk formation, and the manner in which a planetary system’s supply of water arrives from the natal envelope within which its parent star originally formed.

- 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.

- 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.

- Gliese 581: 1 planet might indeed be habitable
12-13-2007 · EurekAlert!
In April, a European team of astronomers announced in Astronomy & Astrophysics the discovery of two possibly habitable Earth-like planets. A&A is now publishing two independent, detailed studies of this system, which confirm that one of the planets might indeed be located within the habitable zone around the star Gliese 581.

- Astronomers discover record 5th planet around nearby star 55 Cancri
11-06-2007 · EurekAlert!
A record-breaking fifth planet has been discovered around 55 Cancri, a yellowish star 41 lightyears from Earth and now the only known star apart from the Sun with 5 planets. The discovery implies that the star has more planets that are smaller than the gas giants found so far and possibly include a rocky, Earth-like planet, according to astronomers Geoff Marcy of UC-Berkeley and Debra Fischer of San Francisco State University.

Iowa State University's Steve Kawaler helped an international team of astronomers make the first discovery of a planet orbiting a star near the end of its life. The news provides a preliminary picture of what could be the Earth's destiny in four to five billion years. The discovery will be announced in the Sept. 13 issue of the journal Nature.

- The star, the dwarf and the planet
10-19-2006 · EurekAlert!
Astronomers have detected a new faint companion to the star HD 3651, already known to host a planet. This companion, a brown dwarf, is the faintest known companion of an exoplanet host star imaged directly and one of the faintest T dwarfs detected in the Solar neighbourhood so far. The detection yields important information on the conditions under which planets form.
