The Most Shocking Discovery in Astrophysics Is 25 Years Old

A quarter of a century after detecting dark energy, scientists are still trying to figure out what it is
One afternoon in early 1994 a couple of astronomers sitting in an air-conditioned computer room at an observatory headquarters in the coastal town of La Serena, Chile, got to talking. Nicholas Suntzeff, an associate astronomer at the Cerro Tololo Inter-American Observatory, and Brian Schmidt, who had recently completed his doctoral thesis at the Center for Astrophysics | Harvard & Smithsonian, were specialists in supernovae—exploding stars. Suntzeff and Schmidt decided that the time had finally come to use their expertise to tackle one of the fundamental questions in cosmology: What is the fate of the universe?
Inside the $1.5-Trillion Nuclear Weapons Program You’ve Never Heard Of

A road trip through the communities shouldering the U.S.’s nuclear missile revival
BY ABE STREEP
The point of the thing was to forever change our concept of power. When the U.S. military assembled a team of scientists, led by physicist J. Robert Oppenheimer, to build a nuclear bomb during World War II with the hope of beating the Nazis to such a terrible creation, many of those involved saw their efforts as a strange kind of civic destiny. The Manhattan Project, wrote Richard Rhodes, Pulitzer-winning author of The Making of the Atomic Bomb, was “compelled from the beginning not by malice or hatred but by hope for a better world.” Oppenheimer himself once said, “The atomic bomb was the turn of the screw. It made the prospect of future war unendurable. It has led us up those last few steps to the mountain pass; and beyond there is a different country.”

Parrots Are Taking Over the World
At Brooklyn’s Green-Wood Cemetery the living get as much attention as the dead. Groundskeepers maintain the 478-acre historic landmark as an arboretum and habitat for more than 200 breeding and migratory bird species. But many visiting wildlife lovers aren’t interested in those native birds. They’re at the entryway, their binoculars trained on the spire atop its Gothic Revival arches. They’ve come to see the parrots.
Extreme Heat Is Deadlier Than Hurricanes, Floods and Tornadoes Combined
When dangerous heat waves hit cities, better risk communication could save lives
Exposure to extreme heat can damage the central nervous system, the brain and other vital organs, and the effects can set in with terrifying speed, resulting in heat exhaustion, heat cramps or heatstroke. It also exacerbates existing medical conditions such as hypertension and heart disease and is especially perilous for people who suffer from chronic diseases. The older population is at high risk, and children, who may not be able to regulate their body temperatures as effectively as adults in extreme conditions, are also vulnerable.

What Is the Future of Fusion Energy?
Nuclear fusion won’t arrive in time to fix climate change, but it could be essential for our future energy needs

- By Philip Ball
Last December physicists working on fusion claimed a breakthrough. A team at the National Ignition Facility (NIF) in California announced it had extracted more energy from a controlled nuclear fusion reaction than had been used to trigger it. It was a global first and a significant step for physics—but very far from enabling practical exploitation of fusion as an energy source.
