Gamma-ray Bursts: Harvesting Knowledge From the Universe’s Most Powerful Explosions

The most powerful events in the known universe – gamma-ray bursts (GRBs) – are short-lived outbursts of the highest-energy light. They can erupt with a quintillion (a 10 followed by 18 zeros) times the luminosity of our Sun. Now thought to announce the births of new black holes, they were discovered by accident. The backstory […]

NASA Tests New Spacecraft Propellant Gauge on Lunar Lander

Editor’s note, Feb. 6, 2024: This article has been updated to clarify that the Radio Frequency Mass Gauge estimates how much propellant is available in a tank. It does not make an exact measurement. It’s easy to measure fuel in tanks on Earth, where gravity pulls the liquid to the bottom. But in space, the game […]

What is Dark Energy? Inside our accelerating, expanding Universe

Some 13.8 billion years ago, the universe began with a rapid expansion we call the big bang. After this initial expansion, which lasted a fraction of a second, gravity started to slow the universe down. But the cosmos wouldn’t stay this way. Nine billion years after the universe began, its expansion started to speed up, […]
