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!
The TRAPPIST-1 system is a treasure trove of possibilities and questions. Observations by JWST have just begun.
The recently discovered Oort cloud comet, Bernardinelli–Bernstein, has the largest known nucleus: 119 km. Here’s what it could do to Earth.
Some think the reason fundamental scientific revolutions are so rare is because of groupthink. It’s not; it’s hard to mess with success.
In the night sky for March of 2022, only stars and the Moon, not planets, will greet you. The real show, however, arrives just before dawn.
We’ve only seen Uranus up close once: from Voyager 2, back in 1986. The next time we do it, its features will look entirely different.
The number of planets that could support life may be far greater than previously thought, a recent discovery suggests.
In terms of the planets we’ve discovered, super-Earths are by far the most common. What does that mean for the Universe?
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!
The best answer we have is, “Life is matter with intentionality.”
The space telescope’s findings challenge the notion of a galaxy brimming with life.
Do you think you know the Solar System? Here’s a fact about each planet that might surprise you when you see it!
If you want to understand what the Universe is, how it began, evolved, and will eventually end, astrophysics is the only way to go.
Human beings are tiny creatures compared to the 92 billion light-year wide observable Universe. How can we comprehend such large scales?
With a new telescope on the horizon, we reflect on the best pictures of space that came before.
Multiple lines of evidence — physical, chemical, and biological — must converge for scientists to conclude that alien life has been found.
Dr. Tyson explains where we might find aliens, why “dark matter” is a misleading term, and why you can blame physics for your favorite team’s loss.
Much like computing technology, the Great Red Spot has been getting smaller and faster over the last few years.
A conversation with an advanced alien species is likely to be simple and to take 1,000 years. It might also be dangerous.
We are traveling in a realm that once exclusively belonged to the gods. Space travel will force humanity to rethink everything.
On Earth, carbon can form millions of compounds, while silicon is largely stuck inside rocks. But elsewhere, silicon could form the basis of life.
At 35 light-years away, it’s also the 2nd coolest, 2nd widest planet ever found. Despite discovering more than 4000 exoplanets, most remain obscure. Although more than 4,000 confirmed exoplanets are known, […]
Astronomers have discovered more than 5,000 confirmed exoplanets — very few of which resemble Earth.
Water is vital for life. Luckily for spacefaring humans, the solar system is full of it.
Infrared, visible, and ultraviolet combine to show us Jupiter’s features as never before. The largest planet in our Solar System, Jupiter, is our own ‘failed star.’ The best evidence-based classification scheme […]
Long before the birth of Julius Caesar, the Roman Republic appointed all-powerful dictators to protect their state in times of crisis. They were remarkably self-restrained and obedient to the Roman Constitution.
The James Webb Space Telescope viewed Neptune, our Solar System’s final planet, for the first time. Here’s what we saw, and what it means.
For thousands of years, humanity had no idea how far away the stars were. In the 1600s, Newton, Huygens, and Hooke all claimed to get there.
Some fascinating observations of K2-18b have come along with horrendous, speculative communications. There’s no evidence for oceans or life.
