Pluto failed to meet the definition of a planet, but some astronomers think there might be a legitimate Planet 9 out there.
After decades of development, whether NASA’s Webb succeeds or fails all comes down to five critical milestones that are only days away.
In 1054, a core-collapse supernova occurred 6500 light-years away. In 2023, JWST imaged the remnant, and might solve a massive mystery.
Former spacewalker Mike Massimino tells Big Think how NASA missions shaped great leaders.
For many, it was just a successful launch like any other. But for scientists around the globe, it was a victory few dared to imagine.
Once science operations begin for James Webb, we’ll never look at the Universe the same way again. Here’s what everyone should know.
With launch costs dropping and enormous numbers of new satellites filling the sky, can’t we just do it all from space?
Some fascinating observations of K2-18b have come along with horrendous, speculative communications. There’s no evidence for oceans or life.
The James Webb Space Telescope finally could answer the age-old question of whether we are alone in the universe.
Even with only 12.5 hours of exposure time, James Webb’s first deep-field image taught us lessons we’ve never realized before.
The last 70 years have taken us farther than the previous 70,000. But can we accomplish more than creating a record saying, “We were here?”
With launch, deployment, calibration, and science operations about to commence, here are 10 facts that are absolutely true.
Fire was crucial to the evolution of human technology. That’s why alien species stuck in the “oxygen bottleneck” may be forever primitive.
Explore how the study of exoplanets is transforming our understanding of ocean formation.
The upcoming launch of the James Webb Space Telescope is the event of a lifetime.
Within the next few decades, we may well have hard evidence for the existence of alien life on worlds light-years distant from Earth.
Back in the 1930s, Fritz Zwicky postulated the existence of dark matter. No one took it seriously until Vera Rubin’s work: 40 years later.
From black holes to dark energy to chances for life in the Universe, our cosmic journey to understand it all is just getting started.
When we look out at the Universe, even with Hubble, we’re only seeing the closest, biggest, brightest galaxies. Here’s where the rest are.
The TRAPPIST-1 system is a treasure trove of possibilities and questions. Observations by JWST have just begun.
The midwest is particularly filled with them.
Finding this missing piece of water’s path through the universe offers clues to how it came to be on Earth.
Astronomers in 2017 caught an image of a supermassive black hole in a galaxy far, far away. Doing it in our own galaxy is a huge milestone.
We knew we’d find galaxies unlike any seen before in its first deep-field image. But the other images hold secrets even more profound.
Though a single measurement is not enough to definitively decide the debate, this is a major win for dark matter proponents.
Many planets will eventually be devoured by their parent star. For the first time, we caught a star in the act, eating its innermost planet!
As Marcel Proust said, “The real voyage of discovery… consists not in seeking new landscapes, but in having new eyes.”
