Milky Way Like a Dolphin

The rising arc of the Milky Way is captured on Mauna Kea observatory, Hawaii, showing the Gemini North telescope in the foreground. This image is the Photo Composite winner in the Light Category of the 7th International Earth and Sky Photo Contest, co-hosted by NOAO and the founding institution “The World at Night”. This annual contest was created to highlight the natural beauty of the night sky and its growing battle with light pollution. The 10 winners of the 2016 contest, selected from more than 1000 entries taken in 57 countries, are shown in the contest video. The panel of judges included NOAO astronomer Connie Walker.

Likely new planet may be in slow death spiral

Astronomers searching for the galaxy’s youngest planets have found one unlike any other: a newborn ‘hot Jupiter’ whose outer layers are being pulled away by the star it orbits. Possibly in a slow death spiral, the planet was studied with multiple telescopes including the Kitt Peak 4-m Mayall.

Giant Planet Discovered Around a Very Young Star

In a rare find, astronomers have detected a young giant planet still embedded in its natal disk of gas and dust. The planet was detected by the wobble it induces in the star that it orbits. The discovery may lend new insights into how planets form. Spectra from the KPNO 2.1m and Mayall telescopes were used in the discovery.

Young Mammoth Cluster of Galaxies Sighted in the Early Universe

Astronomers have uncovered evidence for a vast collection of young galaxies 12 billion light years away. The newly discovered “proto-cluster” of galaxies, observed when the universe was only 1.7 billion years old (12% of its present age), is one of the most massive structures known at that distance. The discovery was made using telescopes at KPNO and Keck Observatory. NOAO Astronomer Arjun Dey is the lead author of the study.

Puffy Giant Planet Discovered by KELT-S Transit Survey

Transiting planets orbiting bright stars provide a golden opportunity to learn about the nature of exoplanets, their composition and origin. KELT-S, a robotic survey of the southern sky that is designed to detect transiting planets orbiting bright stars, reports its first discovery: a highly inflated giant planet. The planet, KELT-10b, is an attractive target for future studies aimed at characterizing planetary atmospheres. NOAO astronomer David James is a founding member of the survey.
