Is there life beyond Earth, even in our Solar System? This mission might be humanity’s best hope of finding it. The biggest question facing humanity might be, “Does life exists beyond […]

The question is no longer “can we” but “should we” edit human embryos.
A fully programmable quantum computer that can outperform any classical computer is right at the edge of today’s technology. Earlier this month, a new story leaked out: Google, one of […]
It may have been captured by Neptune since it formed, but Triton remains king of the Kuiper belt. Our Solar System is arguably the most well-studied corner of the Universe, with […]
In most states, LGBTQ Americans have no legal protections against discrimination in the workplace.
We’d never flown past or imaged a small, isolated Kuiper belt object before. Here’s what we know so far. As 2018 ended and 2019 began, NASA’s New Horizons flew past its […]
For millions of years, this popular color dominated the world.
It’s not volcanic activity, and it’s definitely not from a fire. Mars, our red planetary neighbor, is a vastly different world from Earth. Mars and Earth, to scale, shows how much […]
Different methods of measuring the expansion rate give different values. This one linchpin is key. In science, different methods of measuring the same properties should yield the same results. The expanding […]
No, the Syrian civil war is not over. But it might be soon. Time for a recap.

The first planet beyond ‘naked eye’ astronomy will pass within just 1° of Mars. Although there are eight major planets in the Solar System, most of us never see Uranus or […]
How can physics on the smallest scales affect what the Universe does on its largest ones? Cosmic inflation holds the answer. On a macroscopic level, the Universe appears to be entirely […]
The ices and rock aren’t green, and neither are the tails. So where does a comet’s green color come from? Every so often, with extreme regularity, comets will plunge from beyond […]
13.8 billion years isn’t close to enough time, but if we wait long enough, even our Sun will become one. The Big Bang happened approximately 13.8 billion years ago, and it […]
To go beyond meaning you might need a helpful phrase.
Here are four separate ways you can prove it, even 50 years after-the-fact. 50 years ago, on July 20, 1969, humanity took our first footsteps on the surface of another […]
If everything in nature is made of quantum fields at its core, how do we wind up with particles at all? What is our Universe made out of? At a fundamental […]
In the middle of a great cosmic void, a single, isolated galaxy persists amidst the darkness. It’s about to get a lot lonelier. Here in our own cosmic backyard, the […]
Happy birthday to Pluto, discovered on this day in 1930. Pluto, first discovered in 1930, was no more than a distant dot in our most powerful telescopes. Clyde Tombaugh’s original images […]
The hot Big Bang occurred 13.8 billion years ago, and there’s no other possible answer consistent with what we know today. Conceptually, it might seem like the simplest idea in existence […]
On the eve of receiving the Templeton Prize, Marcelo Gleiser reflects on his life.
From billions of miles away, a faint, single pixel shows us how precious and alone Earth truly is. There are people alive today who can remember a time where no human-made […]
A tiny grain found within a meteorite in Antarctica sheds light on how the solar system itself came to be.
“History is always written by the winners,” goes the saying. It’s also true that history is continually being made, and the identity of the “winner” continually shifts. In his Big […]
If it holds up, it would revolutionize physics and be a slam-dunk Nobel Prize. Here’s why that’s unlikely to be the case. Every so often, an experiment comes along in physics […]
Dogs’ floppy ears may be part of why they and other domesticated animals love humans so much.
In physics, anything that isn’t forbidden must occur. So why don’t the strong interactions violate CP-symmetry? If you ask a physicist what the biggest unsolved problem facing the field today […]
NASA research finds a new direction in searching for signs of life in the Universe.
From religious wars to French poison conspiracies to the counterculture, we look at the origins of Satanism.
