For 550 million years, neutral atoms blocked the light made in stars from traveling freely through the Universe. Here’s how it then changed.
JWST’s revolutionary views arrive in high-resolution at infrared wavelengths. Without NASA’s Spitzer first, it wouldn’t have been possible.
“If we find just one other example of biology out there, then life is not an accident.”
In our Solar System, even the two brightest planets frequently align in our skies. But only rarely is it spectacularly visible from Earth.
This oddball system of three stars might be our best chance at finding nearby life in the Universe.
The Big Bang theory is not threatened, but astrophysicists have some explaining to do.
Now that it’s fully commissioned, the James Webb Space Telescope begins its exploration of the Universe. Here are its first science images!
Space weather poses a tremendous threat to all satellites, knocking all computer systems offline. Is that a recipe for Kessler syndrome?
When we started imaging the Universe with Hubble, every star had four “spikes” coming from it. Here’s why Webb will have more.
Mike Bechtel, chief futurist with Deloitte Consulting LLP, joins Big Think for a wide-ranging look at what’s next — and why.
Explore how the study of exoplanets is transforming our understanding of ocean formation.
Former spacewalker Mike Massimino tells Big Think how NASA missions shaped great leaders.
There are billions of potentially inhabited planets in the Milky Way alone. Here’s how NASA will at last discover and measure them.
The James Webb Space Telescope (JWST) will study many dangerous cosmic phenomena, knowledge of which may help save humanity.
In 1054, a core-collapse supernova occurred 6500 light-years away. In 2023, JWST imaged the remnant, and might solve a massive mystery.
On July 12, 2022, NASA will release the first science images taken with the James Webb Space Telescope. Here’s what to hope for.
At 1,600 light years away, the black hole is practically in our cosmic backyard.
An optical telescope with a massive 20-foot (6-meter) mirror has an eye-popping price tag of $11 billion.
Ever since the Big Bang, cataclysmic events have released enormous amounts of energy. Here’s the greatest one ever witnessed.
Fire was crucial to the evolution of human technology. That’s why alien species stuck in the “oxygen bottleneck” may be forever primitive.
Seven years ago, an outburst in a distant galaxy brightened and faded away. Afterward, a new supermassive black hole jet emerged, but how?
Should we be searching for life on other planets, or technology?
The James Webb Space Telescope has chosen 5 targets for its first science release. Here’s what we know on the eve of JWST’s big reveal!
Some fascinating observations of K2-18b have come along with horrendous, speculative communications. There’s no evidence for oceans or life.
Most potentially hazardous asteroids remain unidentified. NEO surveyor could change that, but only if it’s funded, and soon.
From the tablets of the Babylonians to the telescopes of modern science, humans have always looked to the skies for fundamental answers.
The midwest is particularly filled with them.
Here’s what recent DESI measurements suggest — and why it’s too early to update conventional predictions about the Universe’s distant future.
