'Eight billion bucks or bust': From pirates to 'stupid mistakes' — the wild story of how James Webb Space Telescope almost failed to launch
By Richard Panek published
"Budget overruns, bureaucratic malfeasance, congressional oversight, review-board reckonings, the whole process of rethinking how to test a space telescope from the ground up: Webb had survived them all. One other factor, however, continued to create havoc with the budget and the launch timeline deep into the 2010s — what Menzel called 'stupid mistakes.'"

James Webb Space Telescope smashes its own record to find the earliest galaxies that ever existed

This week, the James Webb Space Telescope zooms in on the iconic Sombrero Galaxy, revealing the first-ever mid-infrared observations of the hat-shaped wonder.

Astronomers spot 1 of the most powerful 'sonic booms' in the universe as massive galaxy crashes into its neighbors
By Ben Turner published
A shockwave caused by the galaxy NGC 7318b slamming into four other galaxies is akin to a "sonic boom from a jet fighter." Astronomers hope the event will reveal vital secrets about the often-violent evolution of our universe.

James Webb Space Telescope discovers mysterious 'red monster' galaxies so large they shouldn't exist
By Ben Turner published
The James Webb telescope has spotted three gigantic "red monster" galaxies that were spawned soon after the Big Bang. They're so large they could rewrite the laws of galactic evolution.

'Ridiculously smooth': James Webb telescope spies unusual pancake-like disk around nearby star Vega — and scientists can't explain it
By Harry Baker published
The nearby bright star Vega is surrounded by a surprisingly smooth, 100 billion-mile-wide disk of cosmic dust, confirming that it is not surrounded by any exoplanets, JWST images reveal. And scientists cannot explain its lack of alien worlds.

James Webb telescope spots 'feasting' black hole eating 40 times faster than should be possible
By Brandon Specktor published
Astronomers using the James Webb Space Telescope have spotted a feeding black hole in the early universe that seems to be eating 40 times faster than is theoretically possible.

James Webb telescope finds 1st possible 'failed stars' beyond the Milky Way — and they could reveal new secrets of the early universe
By Brandon Specktor published
The James Webb Space Telescope may have found dozens of elusive brown dwarfs — strange objects larger than planets but smaller than stars — beyond the Milky Way for the first time ever.
