The words “black hole” might bring to mind an infinite darkness. But the area right around a black hole, called the accretion disk, is actually pretty bright, with matter compressing hotter and hotter into a glowing plasma as it is sucked in. And amid that maelstrom, there are even brighter areas—bursts of energy that astronomers call flares. Scien…

Superfund sites are some of the most polluted areas in the country, containing highly toxic waste such as asbestos, lead, and dioxin. Cleaning them up, which follows a systematic, science-based process as required by law, can take decades.
