Gaia. (spacecraft) Gaia is a space observatory of the European Space Agency (ESA), launched in 2013 and expected to operate until 2025. The spacecraft is designed for astrometry: measuring the positions, distances and motions of stars with unprecedented precision, [5] [6] and the positions of exoplanets by measuring attributes about the stars ...
The Sloan Digital Sky Survey or SDSS is a major multi-spectral imaging and spectroscopic redshift survey using a dedicated 2.5-m wide-angle optical telescope at Apache Point Observatory in New Mexico, United States. The project began in 2000 and was named after the Alfred P. Sloan Foundation, which contributed significant funding.
Wide-field Infrared Survey Explorer. Wide-field Infrared Survey Explorer ( WISE, observatory code C51, Explorer 92 and MIDEX-6) is a NASA infrared astronomy space telescope in the Explorers Program launched in December 2009. [2] [3] [4] WISE discovered thousands of minor planets and numerous star clusters.
The faraway system, called ceers-2112, was spotted by an international team using the James Webb Space Telescope. Like our home galaxy, the newly discovered ceers-2112 is a barred spiral galaxy ...
Locations of the telescopes that make up the EHT array. A global map showing the radio observatories that form the Event Horizon Telescope (EHT) network used to image the Milky Way’s central black hole, Sagittarius A*. The telescopes highlighted in yellow were part of the EHT network during the observations of Sagittarius A* in 2017.
The much-anticipated and much-delayed launch of the next-generation space telescope is now set for Saturday. NASA's James Webb telescope seeks to capture images of the first galaxies and stars in ...
Astrometry is an important step in the cosmic distance ladder because it establishes parallax distance estimates for stars in the Milky Way. Astrometry has also been used to support claims of extrasolar planet detection by measuring the displacement the proposed planets cause in their parent star's apparent position on the sky, due to their ...
Nasa shared stunning images of a star-filled region in our Milky Way thousands of light-years away from Earth. The telescope is designed to conduct infrared astronomy and is able to capture space ...
