Since its launch in 2013, Gaia has been dedicated to creating an accurate three-dimensional map of the Milky Way. Using two high-precision optical telescopes, the spacecraft carefully records the ...

Using in part the NEID spectrograph mounted on the WIYN 3.5-meter Telescope at the U.S. National Science Foundation Kitt Peak ...

Next, the generic approach to planet detection with astrometry is described, with significant discussion of a variety of technical, statistical, and astrophysical issues to be faced by future ...

The European satellite, launched in 2013, has exhausted its gas reserves and is preparing to return to a stable orbit before being 'passivated.' But while the data collection that revolutionized ...

Astrometry tracks star movements to identify gravitational wobbles caused by orbiting planets. AF Lep b is just 23 million years old, making it a very young planet compared to Earth, which is ...
