If you were awaiting screaming death from the skies, you can relax. For now.

Techshot’s 3D BioFabrication Facility successfully printed human heart tissue aboard the International Space Station.

There’s so much we don’t know about fast radio bursts and galactic halos. Combined, we get a unique window on the Universe. Deep in space, mysterious signals known as Fast […]

A new study may help us better understand how children build social cognition through caregiver interaction.

Most homes are using insufficient methods to determine when chicken is done cooking and safe to eat.

The massive Starlink satellite network from SpaceX is causing worries.

Break into the lucrative world of tech with training you can do anywhere.

Big Think has launched a line of apparel and goods that celebrate the life and work of four geniuses.

Following the Booker shortlisting of her novel 10 Minutes, 38 Seconds in This Strange World, British-Turkish author and activist Elif Shafak returns to Think Again to talk about forgotten lives, the nature of evil, and what we mean by progress.

Dark matter must gravitate, so why couldn’t the graviton solve it? One of the most puzzling observations about the Universe is that there isn’t enough matter — at least, matter that we know […]

The Universe is dark, but the distorted light reveals its presence. When we look at the objects in the Universe, the mass just doesn’t add up. A galaxy that was […]

Astronomy’s enduring quest is to go farther, fainter, and more detailed than ever before. Here’s the edge of the cosmic frontier. Astronomers have always sought to push back the viewable […]

The distracting nature of modern media is having a terrible effect on what we learn.

Carbonized papyrus scrolls may again see the light after thousands of years.

When you measure not just light, but light’s polarization, you learn so much more. It’s been over 100 years since the first solution for a black hole was discovered in General […]

And the first sci-fi weapon the Space Force gets is….a device to scramble communications?

Some have suggested that there is no hidden giant out there.

Without this one ingredient, there wouldn’t be enough ‘glue’ to hold the Universe together. Of all the things in the Universe to be thankful for — the stars, planets, atoms, molecules, and […]

Something isn’t adding up, but it isn’t a calibration error. It’s been nearly 100 years since we discovered that the Universe was expanding. Ever since, the scientists who study the […]

Not nearly well enough. And we should all be concerned. In 1859, the science of solar physics truly began with the largest eruption in recorded history: the Carrington event. Prior […]

The origin of the 3rd element on the periodic table was one of the great cosmic mysteries. We just solved it. How did we form the elements that pervade the Universe […]

The space agency is ready to establish a base camp by 2024.

The NICER experiment, designed to measure neutron stars as never before, just released their first pulsar map, and it’s amazing. After typical supernovae, remnant collapsed cores of matter are left behind. […]

Pew Research Center data shows that most people think diversity improves lives in their countries.

All protons have the same exact mass as every other proton. For particles like the Higgs boson, this isn’t true. One of the most puzzling aspects of quantum physics is how […]

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 […]

Using permanent magnets may help to make nuclear fusion reactors simpler and more affordable.

When stars get ejected from galaxies within massive clusters, they go where the dark matter is. Dark matter is one of the greatest mysteries in the Universe, displaying its effects in […]

He’s also credited by some as having coined the phrase “user-friendly.”

And can we devise an experiment to tell, even when we aren’t looking? One of the most bizarre aspects of quantum physics is that the fundamental entities that make up the […]
