""Don’t let fear of getting sucked into a black hole keep you up at night, says Lia Medeiros, a National Science Foundation postdoctoral fellow at the Institute for Advanced Study; you’d have to get really close for that to happen."
The Spektrum-Roentgen-Gamma
(SRG) orbital X-ray observatory and its associated institutions
and industrial partners received the 2021 Marcel Grossmann
Institutional Award. The international collaboration is cited for
the following achievements:
The most accurate distance measurement yet of ultra-diffuse galaxy (UDG) NGC1052-DF2 (DF2) confirms beyond any shadow of a doubt that it is lacking in dark matter. The newly measured distance of 22.1 +/-1.2 megaparsecs was obtained by an international team of researchers led by Zili Shen and Pieter van Dokkum of Yale University and Shany Danieli, a NASA Hubble Fellow at the Institute.
The Gruber Foundation and International Astronomical Union (IAU)
has announced that Matias Zaldarriaga,
Richard Black Professor in the School of Natural Sciences, is a

"Sgr A*, the 4.6-million-solar-mass black hole that lies at the
center of the Milky Way, is normally a fairly quiet beast. The
black hole slowly feeds on accreting material in the galactic
center — but this food source is sparse, and Sgr A*’s...
Stargazers know all too well the challenges of observing the
night sky on a cloudy evening. Fortunately, waiting a night or two
can help to resolve the issue. But what happens if these clouds are
light years away and lie seemingly dormant in the...
The American Astronomical Society (AAS) has announced the
recipients of its 2021 prizes for outstanding achievements in
research and education, among them several current and former
scholars in the IAS School of Natural Sciences.
It is well known that the expansion of the universe is
accelerating due to a mysterious dark energy. Within galaxies,
stars also experience an acceleration, though this is due to some
combination of dark matter and the stellar density. In a new...
