]]> To understand the universe, scientists look to its outliers. “You always want to know about the extreme cases — the special cases that lie at the edge,” said Carsten Gundlach, a mathematical physicist at the University of Southampton. Black holes are the enigmatic extremes of the cosmos. Within them, matter is packed so tightly that, according to Einstein’s general theory of relativity...

]]> Nothing escapes a black hole … or does it? In the 1970s, the physicist Stephen Hawking described a subtle process by which black holes can “evaporate,” with some particles evading gravitational oblivion. That phenomenon, now dubbed Hawking radiation, seems at odds with general relativity, and it raises an even weirder question: If particles can escape, do they preserve any information about the...

]]> Unlike many astronomers, Erin Kara didn’t grow up star-struck. “I don’t have that story of being that little kid staring up at the stars and wanting to do this, which gave me some anxiety,” she said. “Did that make me a fake?” But after discovering astrophysics as an undergraduate, Kara was hooked. Now an observational astrophysicist at the Massachusetts Institute of Technology...

]]> Years before she was even sure the James Webb Space Telescope would successfully launch, Christina Eilers started planning a conference for astronomers specializing in the early universe. She knew that if — preferably, when — JWST started making observations, she and her colleagues would have a lot to talk about. Like a time machine, the telescope could see farther away and farther into the past...
