Telescopes

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.

Jim Gunn shaped the theory of the evolution of the cosmos before building cameras and spectrographs for major observatories like the Hubble Space Telescope.

The astrophysicist Janna Levin reflects on the newly unveiled, first-ever photograph of a black hole.

Astronomers will soon take their first glance at the atmosphere of a distant exoplanet. Sarah Hörst is writing the guidebook for these exoplanetary explorers, one that will reveal what a distinctive atmosphere says about the world underneath.

Priyamvada Natarajan has pioneered the mapping and modeling of the universe’s invisible contents, especially dark matter and supermassive black holes.

Hot spots have been discovered orbiting just outside the supermassive black hole at the galaxy’s center. Their motions have given us the closest look at that violent environment.
