Scientists are finding tumor signals in spit that could be key to developing diagnostic tests for various types of cancer.
When other treatments fail, this radical surgery could help.
Astronomers find a third type of supernova and explain a mystery from 1054 AD.
If argumentation led to nothing, it would soon be thrown into the evolutionary dustbin.
Learning styles are supposed to help learners take ownership of their education, but research doesn’t back up this well-intentioned myth.
Even with all the recent impacts we've seen, it might be more "foe" than "friend" to us.
Even if we traveled at the speed of light, we'd never catch up to these galaxies.
Every observation out into deep space is also a look back in time. Whenever you observe an object, you aren’t viewing it in its present state. When one of Jupiter’s moons […]
Despite Betelgeuse’s recent faintening and brightening, I’d bet on these stars instead. Betelgeuse, a nearby red supergiant, will someday explode. The black hole at the center of the Milky Way should […]
For the cosmos, it’s all too easy being green. Stars come in a wide variety of colors, but never green. Stars form in a wide variety of sizes, colors and masses, […]
If you think it’s just three quarks held together by gluons, you’ll want to read this. At a fundamental level, the Universe is composed of indivisible particles. From macroscopic scales down […]
Out of all the galaxies we know, only a few little ones are missing dark matter. At last, we finally understand why.
NASA’s SOFIA mission is upgraded and back in action, and the Cigar Galaxy makes a perfect target. In theory, cold, neutral gas is the key to stars and galaxies. A visualization […]
We can describe what we see happening, but we don’t understand why. Despite our vast cosmic knowledge, enormous unknowns remain. The quantum fluctuations inherent to space, stretched across the Universe […]
No matter how your year went, Hubble’s views of the Universe never disappoint. Year after year, Hubble’s telescopic views are unparalleled. Saturn, its rings, and 5 of its moons are […]
Only the best physical theories outlast the minds that invented them. Throughout the 20th century, a number of discoveries revolutionized our Universe. The discovery of the interior structure of atoms as […]
Scientists believe they have the answer, but philosophers prove them wrong.
Scientists from John Hopkins find a material for quantum computing.
The laws of physics obey certain symmetries and defy others. It's theoretically tempting to add new ones, but reality doesn't agree.
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 […]
Have any of the stars we can see burned themselves out completely? When we look out across the Universe, we’re also peering back in time. In the early 21st-century, we’ve […]
Puerto Rico's iconic telescope facilitated important scientific discoveries while inspiring young scientists and the public imagination.
America's Space Force has acquired a horse for an important mission.
Most of us will never run a 4 minute mile. But on a bicycle, almost anyone can do it. As human beings, we often take for granted how our bodies work. […]
If the electromagnetic and weak forces unify to make the electroweak force, maybe, at even higher energies, something even greater happens?
Planets are either rocky, like Earth, or gas-rich, like Neptune, with no in-between. What are the different types of planets that exist in the Universe? If all you could see […]
One image can give over 100 times the data we now get from Hubble. NASA’s Hubble Space Telescope, launched in 1990, revealed the previously unseen Universe. The most distant galaxy ever […]
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 […]
By the end of the decade, we may discover one million black holes. A large enough mass in a compact volume inevitably forms a black hole. Both inside and outside the […]
