James Webb Space Telescope

Theory has it that “Population III” stars brought light to the cosmos. The James Webb Space Telescope may have just glimpsed them.

Reports that the James Webb Space Telescope killed the reigning cosmological model turn out to have been exaggerated. But astronomers still have much to learn from distant galaxies glimpsed by Webb.

In a year filled with sweet new observations in astronomy and tantalizing breakthroughs in condensed matter physics, the brand-new space telescope takes the cake.

For Lisa Kaltenegger and her generation of exoplanet astronomers, decades of planning have set the stage for an epochal detection.

The grainy image of a “super-Jupiter” is a sign of what’s to come as the telescope’s exoplanet observations ramp up.

In the days after the mega-telescope started delivering data, astronomers reported new discoveries about galaxies, stars, exoplanets and even Jupiter.

Puzzling particles, quirky (and controversial) quantum computers, and one of the most ambitious science experiments in history marked the year’s milestones.

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.

After the ultra-powerful James Webb Space Telescope launches later this year, Laura Kreidberg will lead two efforts to check the weather on rocky planets orbiting other stars.
