For college students, it’s the early afternoon.
We’ve fooled ourselves before with galaxies that look just like this one. The evidence we have simply isn’t strong enough.
We only detected our very first gravitational wave in 2015. Over the next two decades, we’ll have thousands more.
If there are human-sized creatures walking around on other planets, would we be able to view them directly?
Modern cosmology conjectures different possible fates for the Universe and thus for the end of time. Details depend on which model is right.
COVID-19 and other microbes have shed light on disease spillover from animals to humans, but we can also spillback disease to wildlife.
Stars orbiting black holes were observed to move significantly slower than expected. One explanation centers on dark matter.
The Universe is expanding, and the Hubble constant tells us how fast. But how can it be a constant if the expansion is accelerating?
Looking up at the night sky gives us a glimpse of the Universe beyond our terrestrial concerns. Here’s what’s out there.
More than 90% of sexually active men will be infected with human papillomavirus in their lifetime. The virus may reduce fertility.
More than any other equation in physics, E = mc² is recognizable and profound. But what do we actually learn about reality from it?
Peaking on the night of August 11/12, up to 100 bright meteors per hour will be visible. Here’s how to make the most of it.
Bertrand Russell shows us how to recognize emotional arguments smuggled into presumed statements of fact.
9 minutes of cruel history may cure the anti-progress delusion.
Even if we traveled at the speed of light, we’d never catch up to these galaxies.
Analog could serve as “always-on” computing, while digital is turned on only when necessary.
Your expectations form the way you experience the world.
Sometimes, going “deeper” doesn’t reveal the answers you seek. By viewing more Universe with better precision, ESA’s Euclid mission shines.
It isn’t just identical particles that can be entangled, but even those with fundamentally different properties interfere with each other.
The Universe gravitates so that normal matter and General Relativity alone can’t explain it. Here’s why dark matter beats modified gravity.
Even with only 12.5 hours of exposure time, James Webb’s first deep-field image taught us lessons we’ve never realized before.
Do the health risks outweigh the benefits?
Remembering Frank Drake, who transformed the search for alien life & extraterrestrial intelligence into a full-fledged scientific endeavor.
There could be variables beyond the ones we’ve identified and know how to measure. But they can’t get rid of quantum weirdness.

At this event, you’ll be around to hear the eulogy.
Most of us have heard that the Sun is an ordinary, typical, unremarkable star. But science shows we’re actually anything but average.
Photosynthesis is powerful but very inefficient. Humans can improve on this biochemical process to help the planet.
Exoplanet LP 791-18d is likely to have an atmosphere and liquid water.
