Some astrobiologists believe life is rare, while others believe it is common in the Universe. How can we find out which view is correct?

Without modularization, many epic projects simply would be impossible.
If life is common in the Universe, then where is everybody? Known as the Fermi Paradox, a new project may help solve the riddle.
JWST just found its first transiting exoplanet, and it’s 99% the size of Earth. But with no atmosphere seen, perhaps air is truly rare.
From acclaimed novels to heretical treatises, sometimes a writer just doesn’t want to put their name on the cover.
Our Moon is full of craters, basins, and ancient lava flows. But two large lunar Grand Canyons have the same origin: a single, giant impact.
Red dwarf stars were supposed to be inhospitable. But TOI-700, now with at least two potentially habitable worlds, is quite the exception.
The electromagnetic force can be attractive, repulsive, or “bendy,” but is always mediated by the photon. How does one particle do it all?
Finding out we’re not alone in the Universe would fundamentally change everything. Here’s how we could do it.
Gravitational waves are the last signatures that are emitted by merging black holes. What happens when these two phenomena meet in space?
Hubble’s still going strong after 31+ years. James Webb will never make it that long. Every decision that’s made — in both astronomy and in life — comes with its own set of pros and […]
The image you’re seeing isn’t a hole in the Universe, and the cosmic voids that do exist aren’t hole-like at all.
Physicists have yet to pinpoint the hypothetical matter that keeps galaxies from flying apart. Now they have a new focus.
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 photometric filters for the Vera Rubin Observatory are complete and showcase why they are indispensable for astronomy.
If you want to find life in the Universe, this is how you do it. When it comes to uncovering the ultimate truths about reality, we can only reap what we […]
If you think of the Big Bang as an explosion, we can trace it back to a single point-of-origin. But what if it happened everywhere at once?
How scientists found out that we live in a cosmic aquarium.
Much like computing technology, the Great Red Spot has been getting smaller and faster over the last few years.
Cosmologists are largely still in the dark about the forces that drive the Universe.
Science has come a long way since Mary Shelley penned “Frankenstein.” But we still grapple with the same questions.
From the Big Bang to dark energy, knowledge of the cosmos has sped up in the past century — but big questions linger.
If our nearest star has an Earth-like planet, here’s how we’ll see it. As seen from up close, the signs of not only life, but our intelligent, technologically advanced human civilization […]
Our understanding always will remain incomplete.
The discovery of ultra-bright, ultra-distant galaxies was JWST’s first big surprise. They didn’t “break the Universe,” and now we know why.
A new study proposes that Hawking radiation could be used to find dark matter in places like primordial black holes.
Besides offering an incredibly cool way to get stuff into space, SpinLaunch promises to reduce the cost of a launch by 20-fold.
Galactic archaeology has uncovered a spectacular find: the Milky Way already existed more than 13 billion years ago.
In the 20th century, many options abounded as to our cosmic origins. Today, only the Big Bang survives, thanks to this critical evidence.
