Latest High Accuracy Radial Velocity Planet Searcher Stories
The atmosphere around a super-Earth exoplanet has been analyzed for the first time by an international team of astronomers using ESOâ€™s Very Large Telescope.
Astronomers at the European Southern Observatory (ESO) have discovered five planets orbiting a star in what is being called "the biggest discovery of so-called exoplanets since the first was logged 15 years ago."
Combining observations from the CoRoT satellite and the ESO HARPS instrument, astronomers have discovered the first â€œnormalâ€ exoplanet that can be studied in great detail.
Astronomers have discovered the second super-Earth exoplanet for which they have determined the mass and radius, giving vital clues about its structure.
"For almost 10 years we have tried to find out what distinguishes stars with planetary systems from their barren cousins," says Garik Israelian, lead author of a paper appearing this week in the journal Nature.
Recent discoveries by astronomers have brought the official number of planets outside of our solar system to over 400.
The longest set of HARPS measurements ever made has firmly established the nature of the smallest and fastest-orbiting exoplanet known, CoRoT-7b, revealing its mass as five times that of Earth's.
Astronomers claim to have discovered an exoplanet that is the most similar to Earth in terms of mass than any previously discovered.
Astronomers have announced plans to build an ultra-stable, high-precision spectrograph for the Science and Technology Facilities Council's 4.2-m William Herschel Telescope (WHT - part of the Isaac Newton Group or ING on La Palma) in an effort to discover habitable Earth-like planets around other stars.
ESOâ€™s La Silla Observatory, which is celebrating its 40th anniversary, became the largest astronomical observatory of its time. It led Europe to the frontline of astronomical research, and is still one of the most scientifically productive in ground-based astronomy.
