A team of astronomers has confirmed the existence of a young planet, only 11 million years old, that orbits very close to its star (at 0.05 AU), with an orbital period of 5.4 days. Approximately 5 times the size of the Earth, the new planet is a “super-Neptune” and the youngest such planet known. Observations with ARCoIRIS, the new infrared spectrograph on the 4-m Blanco telescope at the Cerro Tololo Inter-American Observatory (CTIO), played a critical role in measuring the size of the planet. NOAO astronomer David James is a coauthor on the study.

Likely new planet may be in slow death spiral:
Astronomers used the Kitt Peak 4-m Mayall and other telescopes to discover a ‘hot Jupiter’ whose outer layers are being pulled away by the star it orbits.
Galaxy-seeking Robots Geared Up for a Test Run. To prepare for the future 5000-fiber Dark Energy Spectroscopic Instrument, a robotic array of 10 fiber-positioners, ProtoDESI, will be installed on the KP Mayall in August.
New Light on the Big Bang: Spectra from the KPNO Mayall led to the discovery of a small blue galaxy with a near-pristine chemical composition, close to that of the early universe.
Young Mammoth Cluster of Galaxies Sighted in the Early Universe. The discovery was made using telescopes at KPNO and Keck. NOAO Astronomer Arjun Dey is the lead author of the study.
Giant planet discovered around a very young star, still embedded it its natal disk of gas and dust. Spectra from the KPNO 2.1m and Mayall telescopes were used in the discovery.
KELT-S, a robotic survey designed to detect planets orbiting bright stars, reports its first discovery: a highly inflated giant planet. NOAO astronomer David James is a founding member of the survey.
