The Milky Way and colorful celestial objects stretch over Kitt Peak National Observatory, a Program of NSF’s @NOIRLabastro in this 📷of the WIYN 3.5-meter🔭. Above the WIYN 🔭is a pantheon of constellations & their stellar companions. 📷:KPNO/NOIRLab/NSF/AURA/P. Horálek noirlab.edu/public/images/…

New on the NEID science blog: are the orbits of "warm Jupiters" aligned with the spin axes of their stars? We investigate for the case of TOI-1670c. Post and accompanying ApJL paper by Jack Lubin. Science conducted at NOIRLab WIYN Observatory sites.psu.edu/neid/2023/11/2…

New paper led by PI Dr. Arvind Gupta, using NEID data confirms new ‘super-Earth’ exoplanet HD 86728 b. @arXiv preprint: arxiv.org/abs/2409.12315 NOIRLab press release: noirlab.edu/public/announc… 📷: Illustration of Exoplanet HD 86728 b NOIRLab/NSF/AURA/P. Marenfeld

⚠️New paper!⚠️ We have discovered a planet, Gaia-4b, and a brown dwarf, Gaia-5b, using the ESA Gaia spacecraft. Gaia-4b is Gaia's first planet detected with astrometry alone and represents the tip-of-the-iceberg of the 100s-1000s of planets that Gaia is expected to detect.

The NEID spectrograph on the WIYN 3.5-meter Telescope conducted crucial follow-up observations to confirm the existence of exoplanet Gaia-4b — one of the most massive planets known to orbit a low-mass star. noirlab.edu/public/news/no…

Exciting new NEID result led by Guðmundur Stefánsson: radial velocities confirm the first astrometric exoplanet discoveries from Gaia! Post on the NEID blog: sites.psu.edu/neid/2025/02/0…

El espectrógrafo NEID del Telescopio WIYN de 3,5 m realizó observaciones de seguimiento cruciales y confirmó la existencia de Gaia-4b, uno de los exoplanetas más masivos conocidos que orbitan alrededor de una estrella de baja masa. 🔗 noirlab.edu/public/news/no…
