For some reason, when we talk about the age of stars, galaxies, and the Universe, we use “years” to measure time. Can we do better?
There are a few clues that the Universe isn’t completely adding up. Even so, the standard model of cosmology holds up stronger than ever.
Hundreds of these cannabis-related chemicals now exist, both natural and synthetic, inspiring researchers in search of medical breakthroughs.
Most people care what others think of them. In many situations, that can be leveraged for the common good.
Neptune holds records in our Solar System, but the Universe gets even faster. Here on Earth, extreme weather events can cause dramatic wind speed spikes. When hurricanes are at their most […]
From up close, the cracking sound of a thunderclap dominates. From far away, it’s more like a drawn-out rumble. Can science explain why?
Whether they’re gas giants or rocky planets makes all the difference for life. Over the past 30 years, we went from not knowing if there were planets like ours around other […]
New research reveals that the face can affect the shape of the brain through a complex “cross-talk” between the two structures.
Innovative thinking has done away with problems that long dogged the electric devices — and both scientists and environmentalists are excited about the possibilities.
As important as his Nobel Prize-winning technical accomplishments was his ability to communicate to the public.
And the one step we can take to show extraterrestrials we’re figuring it out. Every year, Earth’s meteor showers accomplish two important tasks. This composite photograph shows a large number of […]
Are space and time real like atoms are, or is spacetime just a calculational tool? When most of us think about the Universe, we think about the material objects that […]
Some constants, like the speed of light, exist with no underlying explanation. How many “fundamental constants” does our Universe require?
Two types of nanotechnology, metalenses and metamaterials, could soon make Harry Potter’s invisibility cloak a reality.
When we started imaging the Universe with Hubble, every star had four “spikes” coming from it. Here’s why Webb will have more.
Did the Milky Way form by slowly accreting matter or by devouring its neighboring galaxies? At last, we’re uncovering our own history.
We know it couldn’t have began from a singularity. So how small could it have been at the absolute minimum?
After mammoth investments and two decades of anti-aging research, what do immortality proponents have to show for it?
It peaks the nights of August 11–13, but it’s no longer the year’s most reliable meteor shower. Every year, beginning in mid-July, planet Earth commences passing through an enormous debris […]
From high school through the professional ranks, physicists never tire of Newton’s second law.
Einstein’s laws of gravity have been challenged many times, but have always emerged victorious. Could wide binary stars change all that?
The tiny swimmers appear to transmit signals that “persuade” the female body to have a baby.
As Abraham Lincoln famously said, “If you want to test a man’s character, give him power and a plate of cookies.” (Something like that.)
In the early 20th century, a young biochemist named Alexander Oparin set out to connect “the world of the living” to “the world of the dead.”
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.
Just a small gesture or a thoughtful comment can often alter a situation, or people’s perceptions of it, in ways that relieve tensions and make them feel appreciated and included.
Life arose on Earth very early on. After a few billion years, here we are: intelligent and technologically advanced. Where’s everyone else?
