Some fascinating observations of K2-18b have come along with horrendous, speculative communications. There's no evidence for oceans or life.
How can you maximize the amount of love and happiness in your life? One of history's greatest scientists found the answer: with math.
Chemical changes inside Mars' core caused it to lose its magnetic field. This, in turn, caused it to lose its oceans. But how?
A more distant galaxy liked the lens so much that it went and put a ring on it. Here's the science behind this remarkable cosmic object.
This measurement is crucial to confirm that one of the assumptions of Einstein’s theory of gravity is valid.
The hot Big Bang was an energetic, brilliantly luminous event. Today's Universe is alight with stars. But in between, the dark ages ruled.
An enormous amount of antimatter is coming from our galactic center. But the culprit probably isn't dark matter, but merely neutron stars.
Finding a tiny planet around bright stars dozens or hundreds of light-years from Earth is extremely difficult.
Named "Supernova H0pe," it shows how JWST plus gravitational lensing can be used to solve the greatest puzzle facing astronomy today.
An annular eclipse is coming to Earth on October 14, 2023. Six months later, a total solar eclipse is headed our way. Here's the reason why.
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.
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.
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.
