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.
Scientists have never been able to adequately explain where lightning comes from. Now the first detailed observations of its emergence inside a cloud have exposed how electric fields grow strong enough to let bolts fly.
The James Webb Space Telescope has the potential to rewrite the history of the cosmos and reshape humanity’s position within it. But first, a lot of things have to work just right.
Radio waves, longer and less energetic than visible light, give astronomers access to some of the most obscure physics in the cosmos.
Professional astronomers may not point their telescopes by hand anymore, but COVID-19 has still closed observatories and impeded research.
After a burst lit up their telescope “like a Christmas tree,” astronomers were able to finally track down the source of these cosmic oddities.
As astronomers get better at finding the comets and asteroids of other stars, they’ll learn more about the universe and our place in it.
Astronomers have discovered a complex planetary system still swirling into existence.
Astronomers are puzzling over a paucity of planets in the galaxy measuring between 1.5 and two times Earth’s size.
