Paired with super telescopes, model Earths guide hunt for life

– Cornell University astronomers have created five models representing key points from our planet’s evolution, like chemical snapshots through Earth’s own geologic epochs. The models will be spectral templates for astronomers to use in the approaching new era of powerful telescopes, and in the hunt for Earth-like planets in distant solar systems.

NEID Exoplanet Instrument Sees First Light

The new NEID instrument, now installed at the 3.5-meter WIYN telescope at Kitt Peak National Observatory in Southern Arizona, USA, has made its first observations. The NSF-NASA funded instrument is designed to measure the motion of nearby stars with extreme precision — roughly three times better than current state-of-the-art instruments — allowing us to detect, determine the mass of, and characterize exoplanets as small as Earth.
