On Friday, the moon will pass through the Earth's outer shadow, known as the penumbra.

At 35 light-years away, it’s also the 2nd coolest, 2nd widest planet ever found. Despite discovering more than 4000 exoplanets, most remain obscure. Although more than 4,000 confirmed exoplanets are known, […]
‘Reductio ad absurdum’ won’t help you in an absurd Universe. Throughout history, there have been two main ways humanity has attempted to gain knowledge about the world: top-down, where we […]
And a combination of all three might take us farther than ever. If you want to see the farthest objects in the Universe, you have to know not only where to […]
After more than two decades of precision measurements, we've now reached the "gold standard" for how the pieces don't fit.
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 only doubts are completely unreasonable. Where did the virus that causes COVID-19, SARS-CoV-2, come from? Over the past few weeks, there’s been a tremendous push — largely among politicians but also […]
Carbon dating allows us to know exactly when ice was melted for drinking water in pre-Columbian America.
On the largest scales, galaxies don't simply clump together, but form superclusters. Too bad they don't remain bound together.
Researchers make the case for "deep evidential regression."
Join Maria Konnikova live at 11am EDT tomorrow on Big Think!

An artist’s impression of what the fully-deployed James Webb Space telescope will look like from the perspective of an observer on the ‘dark’ (non-Sun-facing) side of the observatory. (NORTHRUP GRUMMAN) […]
The Big Bang is our accepted origin of the Universe. But is there another possibility? Since the mid-1960s and the discovery of the Cosmic Microwave Background, the Big Bang has […]
Deniers will never stop misleading others. Here’s the truth. Every so often, advocates of a fringe theory — one that doesn’t fit the evidence as well as the mainstream theory — do what they can […]
The laws of physics aren’t changing. The Earth is. When it comes to any physical science, we know that the fundamental rules governing how the Universe works remain constant with time. […]
Jonathan Berman wants us to have better dialogues.
And either way, is energy or information conserved? When two things in the Universe that “always” occur meet one another, how do you know which one will win? Gravitational waves, […]
A volcano in California is a hot spot for conspiracy theorists.
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 […]
It happened more than once, and needed to. Here’s why. If there’s one thing you can be certain about when it comes to outer space, it’s that it’s transparent, not opaque, […]
With launch costs dropping and enormous numbers of new satellites filling the sky, can't we just do it all from space?
In our Universe, a left hand reflected in a mirror or pond appears to be a right hand. While most of the laws of nature are symmetric under reflections, obeying […]
Are dark matter and dark energy both two sides of the same coin? When it comes to the Universe, what you can easily see isn’t always reflective of all there is. […]
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 […]
How can you "touch the Sun" if you've always been inside the solar corona, yet will never reach the Sun's photosphere?
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 […]
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 […]
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 […]
You’d have to throw out a lot of known physics for this to even be a possibility. Here’s why. It’s an undeniable scientific fact that dark matter must exist in order […]
If a large asteroid strikes Earth, it has the potential to release an enormous amount of energy, leading to local or even global catastrophes. The strike that led to the […]
