Objective reality exists, but what can you know about it that isn’t subjective. According to some neuroscientists, not much.
On other planets, blue skies and red sunsets aren’t the norm.
If you had a clear western horizon, you had your shot at this view! On September 9, 2021, the Moon and Venus nearly overlapped. A simulated view of the post-sunset skies […]
Humans are more likely to have “first contact” with an advanced alien civilization, according to a recent NASA-funded paper.
The microbes that eventually produced the planet’s oxygen had to breathe something, after all.
It is impossible for science to arrive at ultimate truths, but functional truths are good enough.
On the morning of March 31, 2020, these three worlds will be at their mutual closest in 20 years. For the past few weeks, Mars, Saturn, and Jupiter have all shone […]
I’m not saying it’s not aliens, but it’s not aliens. When it comes to life in the Universe, we still have no definitive answer to the biggest question of all, “are […]
We’ve argued over ideology for far too long. It’s time to pick a better route to prosperity. In every civilized society around the world, there’s a trade-off that must be […]
A meteorite that smashed into a frozen lake in Michigan may explain the origins of life on Earth, finds study.
A physicist creates an AI algorithm that predicts natural events and may prove the simulation hypothesis.
A new batch of papers reveals some of Mars’ subterranean secrets.
Is the Universe the same everywhere? Or are there truly ‘special places’ around? For practically all of human history, one assumption about our place in the Universe had long gone unchallenged: […]
With sodium-sensitive eyes, we’d see it every new Moon. With no detectable gases, the Moon appears to be atmosphere-free. The Moon as seen from a view above the majority of Earth’s […]
All scientific theories, at some level, are wrong. That’s why consensus is so vital. There are two important and common words that, when used scientifically, have a very different meaning than […]
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 […]
It’s not a gambit. It’s not fraud. It’s not an opinion. And it’s not biased like you think it is. Most of us, when we think about what science is, default […]
Three lines of evidence point to the idea of complex, multicellular alien life being a wild goose chase. But are we clever enough to know?
The lessons we’ve learned here on Earth will affect how we govern a new world.

The Mars 2020 rover is set to launch in July of the same year, setting the stage for years and years of science on the Red Planet.
Science can teach us so much about our planet, but something more must compel us to take care of it. If you want to understand our planet, the best way to […]
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 […]
Just say no to artist’s illustrations. This is what the Universe actually looks like. The Universe we observe often surpasses our greatest imaginings. This 20-year time-lapse of stars near the center […]
The space agency is ready to establish a base camp by 2024.
A fairly old idea, but a really good one, is about to hit the store shelves.
Science doesn’t exist in a cultural and existential vacuum and its teaching shouldn’t either.
A NASA-sponsored competition asks participants to improve the design of a bucket drum for moon excavation.
Scalars, vectors, and tensors come up all the time in science. But what are they? One of the major goals of science is to describe our reality as accurately as possible. […]
