Latest Hipparcos Stories
Astronomers have used a worldwide network of radio telescopes to resolve a controversy over the distance to a famous star cluster -- a controversy that posed a potential challenge to scientists' basic understanding of how stars form and evolve.
The European Space Agency’s (ESA) billion-star surveyor mission is slowly beginning to see more clearly. The Gaia spacecraft took a test image of a dense star of clusters in the Large Magellanic Cloud to help fine tune its instruments.
A new planetarium show, Journey to a billion Suns, premieres today in Hamburg, Germany, to tell the fascinating story of mapping the Milky Way, from ancient times to ESA’s recently launched Gaia mission.
Gaia will be embarking on a five-year mission to map the stars and create a highly accurate 3D map of our Milky Way Galaxy. ESA said the spacecraft has completed final preparations in Europe and is ready to depart to its final pit stop on Earth before launch.
The ink is drying on a brand new birth certificate for a star that's been around for a very long time. New calculations using NASA'S Hubble Space Telescope have enabled a group of astronomers to take an important step closer to reconciling the age of this star, and the age of the Universe.
ESA's mission to measure the precise positions of a billion stars reached an important milestone on September 3 with the delivery of its first primary mirror.
Gaia, ESAâ€™s next-generation star mapper, will be carried into space by a Soyuz-STB/Fregat launch vehicle from Europeâ€™s Spaceport in French Guiana.
Having the sharpest pictures always is a big advantage, and a sophisticated radio-astronomy technique using continent-wide and even intercontinental arrays of telescopes is yielding extremely valuable scientific results in a wide range of specialties.
It has been ten years since the release of the Hipparcos and Tycho catalogues, the first astrometric catalogues produced from observations in space. The Hipparcos catalogue has since been re-processed and fine-tuned, providing the best map of our galaxy to date.
