Wondering about that New Year’s Resolution to get more exercise?

Good news from the Milky Way’s nearest neighbors, the Magellanic Clouds: it’s never too late to get active.

Art meets science as the Sloan Digital Sky Survey has officially appointed its first artist in residence.

Tim Fitzpatrick, an installation artist from Fife, Scotland, will continue his ongoing work in his new official capacity, bringing his unique perspective to an already-rich collaboration.

The observers’ log said: “Wow, what a night!”

This week marks the twentieth anniversary of “first light” for the telescope behind the Sloan Digital Sky Survey (SDSS), which has gone on to create by far the largest three-dimensional map of the Universe ever made.

Today, astronomers from the Sloan Digital Sky Survey (SDSS) announced new measurements of the masses of a large sample of supermassive black holes far beyond the local Universe.

Astronomers with the Sloan Digital Sky Survey (SDSS) have learned that the chemical composition of a star can exert unexpected influence on its planetary system — a discovery made possible by an ongoing SDSS survey of stars seen by NASA’s Kepler spacecraft, and one that promises to expand our understanding of how extrasolar planets form and evolve.

Today, astronomers from the Sloan Digital Sky Survey report a surprising new answer to that important question: feedback from supermassive black holes blocks star formation, even in some of the smallest galaxies.

How far away is that galaxy? Our entire understanding of the Universe is based on knowing the distances to other galaxies, yet this seemingly-simple question turns out to be fiendishly difficult to answer.

The next generation of the Sloan Digital Sky Survey (SDSS-V), directed by Juna Kollmeier of the Carnegie Institution for Science, will move forward with mapping the entire sky following a $16 million grant from the Alfred P. Sloan Foundation.
