Beyond the
Kuiper Belt Edge

Two new Kuiper Belt objects, 2014 FZ71 and 2015 FJ345, are among the most distant bodies in the Solar System. They are always further than 50AU from the Sun, and only Sedna and 2012 VP113 have larger perihelia. The discovery was made using data from DECam on the Blanco 4-m telescope at CTIO.

Young Super-Neptune Offers Clues to the Origin of Close-In Exoplanets

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.

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.
