How does star-formation, occurring in small regions within galaxies, affect the entire host galaxy that contains it? JWST holds the answers.
Scientists may have detected the somewhat smelly chemical dimethyl sulfide on a planet 120 light-years from Earth.
Dark matter hasn't been directly detected, but some form of invisible matter is clearly gravitating. Could the graviton hold the answer?
When science is a source of spirituality in people’s lives, they feel happy and engaged.
A spherical structure nearly one billion light-years wide has been spotted in the nearby Universe, dating all the way back to the Big Bang.
In 1987, the closest supernova directly observed in nearly 400 years occurred. Will a pulsar arise from those ashes? JWST offers clues.
The asteroid is expected to come within 140,000 miles of Earth — well inside the moon’s orbit.
Looking at our planet with post-Copernican eyes has the power to change how we relate to it and each other.
With ~400 billion stars in the Milky Way and 6-20 trillion galaxies overall, that makes for a lot of stars. But not as many as you'd think.
The biggest, brightest galaxies are the easiest to spot, but the tiniest ones teach us about how the Milky Way assembled and grew up!
A clock, designed and built in Europe, ran hopelessly at the wrong rate when brought to America. The physics of gravity explains why.
The "Ring Nebula," known for almost 250 years, is so much more than a Ring. With JWST's capabilities, we're seeing more than ever before.
Despite the vast number of planets in the Universe, Earth's specific evolutionary history guarantees that its life forms — including humans — are utterly unique.
The first observational evidence showing the Universe is expanding is 100 years old now: in 2023. Here's the story of its 100th anniversary.

Ever wonder what would happen if we got sucked into a black hole? Turns out we could live in it for a while — if it was big enough.
How fast is the Universe expanding? Two major methods disagree. New JWST data, just released, strengthens this Hubble tension even further.
Whether you call it 10 quintillion, 10 million trillion, or 10 billion billion, it's a 1 followed by 19 zeroes.
As Marcel Proust said, “The real voyage of discovery... consists not in seeking new landscapes, but in having new eyes.”
How scientists are hearing the gravitational background "hum" of the Universe for the very first time.
Einstein's laws of gravity have been challenged many times, but have always emerged victorious. Could wide binary stars change all that?
Each of our three nearest stars might have an Earth-like planet in orbit around it. Here's what we'll learn when we finally observe it.
From when its light was emitted, the El Gordo galaxy cluster might be the most massive object in all of existence. Here's how JWST sees it.
Each year in mid-August, Earth plows through the debris stream of an enormous comet, creating the Perseids. 2023's show will be magnificent!
Ultracold gases in the lab could help scientists better understand the universe.
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.
Can two planets stably share the same orbit? Conventional wisdom says no, but a look at Saturn's moons might tell a different story.
All stars, eventually, run out of fuel and die. Given all the stars we can see and the vast distance to them, are any of them already dead?
The hunt for the elusive particles continues.
We may be the last generation born not knowing if we are alone in the Universe.
