In 1995, Hubble peered at the Pillars of Creation, forever changing our view. Now in 2022, JWST completes the star-forming puzzle.
Our understanding always will remain incomplete.
Are you unhappy with how various events in your life turned out? Perhaps, in a parallel Universe, things worked out very differently.
It's literally the one and only trick that separates top-notch physicists from crackpots, dropouts, and those who can't cut the mustard.
Dogs are seen as more likely to leap without looking – possibly a trait shared with their owners.
If you can model anything in the Universe with an equation, mathematics is how you get the solution(s). Physics must go a step further.
In special relativity, the statement that two events happened at the same time is meaningless.
The 557-million-year-old specimen challenges the theory that animal body plans were laid out in the Cambrian explosion.
Human beings are descendants of these early tetrapods – at least those who made a new life on land.
Heart muscle is shaped like a spiral, a mystery that has eluded scientists since 1669. New research has recreated the structure.
Searching for dark matter, the XENON collaboration found absolutely nothing out of the ordinary. Here's why that's an extraordinary feat.
Science and the sacred both allow us to retain our sense of wonder, even as disaster seems to swirl around us.
At all distances, the Universe expands along our line-of-sight. But we can't measure side-to-side motions; could it be rotating as well?
When stars form, they emit energetic radiation that boils gas away. But it can't stop gravitational collapse from making even newer stars.
The long-standing debate over whether dinosaurs were more like birds or lizards is drawing to a close.
On July 12, 2022, NASA will release the first science images taken with the James Webb Space Telescope. Here's what to hope for.
The sky is blue. The oceans are blue. While science can explain them both, the reasons for each are entirely different.
The idea of black holes has been around for over 200 years. Today, we're seeing them in previously unimaginable ways.
Probably not. Even though we're still investigating the origin of life, the evidence suggests that cells came much later.
Volcanic activity caused the end-Triassic mass extinction 200 million years ago. The dinosaurs survived and rose to dominance.
There is strong evidence that invertebrates are sentient beings.
We've fooled ourselves before with galaxies that look just like this one. The evidence we have simply isn't strong enough.
An optical telescope with a massive 20-foot (6-meter) mirror has an eye-popping price tag of $11 billion.
The idea of "absolute time" was our default for millennia. But time is relative, as gravity and motion both cause time to dilate.
It's possible to measure philosophy's progress in two ways. But is that really the point?
The relationship between these two ways of thinking about the world deserves deeper exploration.
From life on Earth to the planet itself, there are four ways our planet will actually experience "the end," no matter how we define it.
