Extrasolar Planets

A Jupiter-sized extrasolar planet orbits in synchrony with its star's rotation, report European astronomers .  

Paris, France (ESA) Jul 25, 2008 - A team of European scientists working with COROT have discovered an exoplanet orbiting a star slightly more massive than the Sun. After just 555 days in orbit, the mission has now observed more than 50 000 stars and is adding significantly to our knowledge of...  

Honolulu HI (SPX) Jul 22, 2008 - An international team of astronomers, including Dr. Adam S. Bolton of the University of Hawaii's Institute for Astronomy, has recently announced a finding that helps to settle a long-standing debate over the relationship between mass (the amount of matter) and...  

NASA's photos have traditionally featured stunning galaxies, planets, stars, comets, asteroids and other scientific snapshots. But the recent selection of ...  

Abstract Designed for students who have a basic understanding of physics and mathematics, this text provides a fundamental, three-in-one introduction to astronomy, astrophysics, and cosmology.  

“These candidates could well explain one of the big puzzles plaguing astronomy today. We know that the Universe was reionised within the first 5-600 million ...  

The new observational potential offered by space stations and the availability of powerful and highly specialized computers have revealed novel aspects of the fascinating realm of galaxies, quasars, stars and ...  

Observations of planets orbiting other stars are becoming increasingly common as astronomical techniques become more and more sophisticated. But some extrasolar planets have a stronger than normal spectroscopic signature, often stronger than their optical signature. What could be causing this? In...  

HD 189733b is a Jupiter-sized extrasolar planet orbiting a yellow dwarf star. Due to its size can compact orbit, HD 189733b is one of the most studied extrasolar planets. HD 189733b shares many similar characteristics as HD 209458b (a.k.a. "Osiris," as I reported in a UT article yesterday), and...  

A unique home video may help astronomers identify Earth-like planets that are slightly out of our zip code....  

Makemake of the Outer Solar System Credit: R. Hurt (SSC-Caltech), JPL-Caltech, NASA Explanation: Recently discovered Makemake is one of the largest objects known in the outer Solar System. Pronounced MAH-kay MAH-kay, this Kuiper belt object is only slightly smaller than Pluto, orbits the Sun only...  

Scottish scientists have been given cash backing to develop crucial elements of the successor to the Hubble telescope, which will be the most advanced window on distant galaxies in the history of space exploration. The funding marks a remarkable ...
