The space telescope is one of the most ambitious scientific projects ever undertaken. Marcia Rieke and Nikole Lewis, two of the scientists leading JWST investigations, talk to Steven Strogatz about how it may transform our understanding of the universe.
In 2019, the Event Horizon Telescope released a historic image of a supermassive black hole in another galaxy. The follow-up — an image of Sagittarius A* — shows it shimmering at the center of our own.
Researchers say we’re on the cusp of “GoPro physics,” where a camera can point at an event and an algorithm can identify the underlying physics equation.
Dwarf galaxies weren’t supposed to have big black holes. Their surprise discovery has revealed clues about how the universe’s biggest black holes could have formed.
