The James Webb Space Telescope released its first science images today. Here's what these images show us.
The James Webb Space Telescope's first year of observations promises to reveal exoplanet atmospheres and surfaces, infant galaxies, and maybe even the first black holes.
At the extremes: A hot Jupiter reveals extreme chemistry on a sizzling world, and a cold Jupiter sheds light on giant planet formation.
The transit of a large cloud of protoplanetary rubble across the face of a young star gave the Spitzer Space Telescope our best view yet of planetary evolution in action.
A new instrument on a powerful telescope has enabled astronomers to discover another planet around our nearest stellar neighbor.
Since its 2018 launch, the unassuming TESS satellite has found 175 confirmed exoplanets (so far) among 5,000 “objects of interest.”
Astronomers may have found a second Neptune-size exomoon hidden in the retired Kepler space telescope’s data.
This week astronomers have announced the completion of the largest 3D map of galaxies across the cosmos, plus exquisite radio observations show what happens when a stellar intruder interrupts planet formation.
Astronomers witness the unfurling of a black hole-powered mushroom cloud, a baby super-Jupiter, and a magnetic "tunnel" around the solar system.
