There are exposed planetary cores orbiting stars, and we may have already found them. When we take a look at the planets in our Solar System, there’s a pretty clear difference […]

As long as it remains operational, we’ll have a chance to conduct groundbreaking science with it. In the history of spaceflight, only five spacecraft ever launched by humanity possess enough energy […]
Light-emitting tattoos could indicate dehydration in athletes or health conditions in hospital patients.
Binary pulsars are doing what no other measurement has done: measure our galactic acceleration directly. Even though the majority of the matter that makes up our Universe may be completely […]
A revolution of the mind must occur in order for humanity to succeed on a finite planet.
The center of our Sun tops out at 15 million K, but nuclear bombs can get nearly 20 times hotter. Here’s how. In terms of raw energy output, nothing on our […]
Find a clear western horizon after sunset, and this ‘triple treat’ of a dance can be yours. Every once in a while, the night sky provides a spectacular feast for our […]
Democritus also did not believe in free will but was still known as the “laughing philosopher.”
Walter Pitts rose from the streets to MIT, but couldn’t escape himself.
According to the Standard Model, the leptons and antileptons should all be separate, independent particles from one another. But the three types of neutrino all mix together, indicating they must […]
Think they all burn through their fuel, die, and leave white dwarfs, neutron stars, or black holes behind? Think again. The day will come when our Sun, like most stars, can […]
A textbook pregnancy consists of three trimesters. The baby develops at a relatively predictable rate during this time, from pomegranate seed to avocado to watermelon. And mom’s body adapts accordingly […]
Seek pleasure and avoid pain. Why make it more complicated?
The history of the Universe is forever imprinted in our own bodies. We can learn a lot about the history of the Universe just by looking at each of our own […]
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 […]
How do these little beasties detect light anyway?
Diogenes was no doubt odd, but Cynicism might just help our overcrowded lives.
The ANITA experiment found cosmic rays shooting out of Antarctica. One interpretation claims “parallel Universes,” but is that right?
Planets can emit radio waves. For the first time, we’ve picked them up from outside the solar system.
Their goal is a digital model of the Earth that depicts climate change in all of its complexity.
A new study finds the rocks that first formed Earth carried with them enough hydrogen for three times the water we have today.
Researchers find a key clue to the evolution of bony fish and tetrapods.
A new study explains how a chaotic region just outside a black hole’s event horizon might provide a virtually endless supply of energy.
A physicist creates an AI algorithm that predicts natural events and may prove the simulation hypothesis.
On the largest scales, galaxies don’t simply clump together, but form superclusters. Too bad they don’t remain bound together.
Dust sticking to things on the moon is a serious problem researchers are trying to solve.
Even the ones hunting for aliens aren’t excited. Here’s the reason why. In this world, there are very few issues more polarizing than the notion of aliens. For as long as […]
Even though no human has stepped foot on the Moon’s surface in 50 years, the evidence of our presence there remains unambiguous.
The Sun will eventually become a red giant star, swallowing Mercury and Venus in the process. But what will happen to Earth? There are a few existential questions we can ask […]
Differences in the way that the Hubble constant—which measures the rate of cosmic expansion—are measured have profound implications for the future of cosmology.
