The Latest Breaking News from JWST

An exclusive interview with "Infinite Cosmos'" astrophysicist author Ethan Siegel.

The inside-out growth of this ancient galaxy could teach us something about the history of our own Milky Way and how it compares to the rest of the universe.

The James Webb Space Telescope (JWST) is the largest and most powerful space telescope built to date. Since it was launched in December 2021 it has provided groundbreaking insights. These include discovering the earliest and most distant known galaxies, which existed just 300 million years after the Big Bang.

Beyond our solar system, countless alien worlds of lava, ice, water and noxious gas swirl through the cosmos. Here are some of the strangest exoplanets that scientists have discovered so far.

Using the James Webb Space Telescope astronomers have found that a strange inflated exoplanet is even weirder than they realized finding a strange asymmetry in its atmosphere.

The Hubble tension, a longstanding problem in cosmology, could potentially be relieved if early dark energy is taken into account.

The James Webb Space Telescope has imaged a collision between two galaxies that appears to have created a beaming smile in space.

For the past few years, a series of controversies have rocked the well-established field of cosmology. In a nutshell, the predictions of the standard model of the universe appear to be at odds with some recent observations.

The presence of hydrated minerals, including possibly water-ice, might indicate an unexpected origin for Psyche, far from the sun.

Astronomers have found that Ariel, a moon of Uranus, has some of the most carbon dioxide-rich deposits in the solar system, hinting at a buried water ocean.

Using the James Webb Space Telescope, astronomers have investigated a super-Jupiter that is one of the coldest exoplanets ever directly imaged.
