Thirty years ago, Martin Rees , a former Member in the School of Natural Sciences and current IAS Trustee, predicted that bright flares produced when a star is torn apart by a black hole—what astrophysicists now call tidal disruption events (TDEs)—could be used to...
Ewine van Dishoeck , Trustee of the Institute for Advanced Study, has been recognized by the Norwegian Academy of Science and Letters, the Kavli Foundation, and the Norwegian Ministry of Education and Research with the 2018 Kavli Prize in Astrophysics for her combined contributions...
Juna Kollmeier , former Junior Visiting Professor in the School of Natural Sciences, wants to understand the substance of the universe: What forms space structures like galaxies, supermassive black holes, and the intergalactic medium that fills the gaps between galaxies? “On every physical scale...
Juan Maldacena , Carl P. Feinberg Professor in the School of Natural Sciences, and Member Douglas Stanford will give the public lecture “ The Cool Alter-Ego of a Black Hole ,” on Friday, May 4 , which will take...
“Trying to understand Hawking’s discovery better has been a source of much fresh thinking for almost 40 years now, and we are probably still far from fully coming to grips with it. It still feels new,” said Edward Witten , Charles Simonyi Professor in...
The American Astronomical Society awarded former Members in the School of Natural Sciences with prestigious prizes for outstanding achievements in scientific research, instrument development, and writing.
Since 2009, astrophysicists have been trying to explain the abundance of gamma radiation diffusing from the center of the Milky Way, a production of high-energy radiation far beyond what the known gamma-ray sources suggest. Tracy Slatyer, former Member in the School of Natural Sciences, has...
Everything that humans have seen up until now exists in the 4.9 per cent of the universe that interacts with light. The rest is hidden from view. Most of it, physicists believe—68.3 per cent—is dark energy, an enigmatic force that drives...
The life of Subrahmanyan Chandrasekhar , astrophysicist and former Member in the School of Natural Sciences, was celebrated with Google Doodle's October 19 animation. Published on what would have been Chandrasekhar's 107th birthday, the Doodle is a simple illustration of one of his most...
Dark matter is as tangible as stars and planets to most astronomers. We routinely map it out. We conceive of galaxies as lumps of dark matter with dabs of luminous material. We understand the formation of cosmic structure, as well as the evolution of the...
For as long as modern science has existed, scientists have attempted to answer such unanswerable questions by trying to either reconcile science and religion, like Galileo did in defending his theories against the Inquisition and Ada Lovelace did in considering the interconnectedness of the universe,...
After a decade of searching and verification, a research team revealed a new exoplanet, and you could say it’s coming in hot. The orb is the hottest giant exoplanet ever found, according to a study published in Nature . “KELT-9b” intrigues astronomers not...
