Some of them may have formed just 200 million years after the Big Bang. When we look out at the Universe, we’re not seeing objects as they are today, but rather […]
In her book The Art of Rest, one researcher conducted a thorough analysis of the top 10 activities we find most restful.
It’s one of the two best meteor showers of the year. Don’t let the full Moon stop you. Every year, as the Earth intercepts the debris streams of comets and asteroids […]
Here’s how to harness the sunlight, even if you’re sitting in an office all day.
Take the circumstances in your life seriously, but not literally. Here’s why.

Helium and carbon are made copiously in the interiors of stars. But the in-between elements? They’re rarities everywhere. If you were to take every element in the periodic table and […]
Today, our observable Universe extends for 46 billion light-years in all directions. But early on, things were much smaller. There are few things we can conceive of that are as mind-bogglingly […]
From outside a black hole, all masses take an infinite amount of time to cross the event horizon. How, then, can black holes grow? Every Milky Way-sized galaxy should contain hundreds […]
Using atoms to probe the Universe reveals the complete Standard Model. If you wanted to uncover the secrets of the Universe for yourself, all you’d have to do is interrogate […]
An entire Universe of possibilities await stars like our own, even after they run out of fuel. One of the most profound rules in all the Universe is that nothing lasts […]
A black hole punched a hole 15 Milky Ways across in a galaxy cluster’s gas, by far the largest ‘kaboom’ ever seen. The Universe, everywhere we look, is full of cataclysmic […]
And how cutting just $1 billion per year in funding from NASA’s budget would be a catastrophe for science. When you think of the great cosmic beyond and what we know […]
Sophists used rhetoric and debate to arrive at practical truths.
Black holes are regions of extreme gravity, but dark matter barely interacts at all. Do they play well together? Black holes are some of the most extreme objects in the […]
They said the “missing half” of the Universe’s matter was just found. But what they found barely makes a dent to the big picture. When we look up into the great […]
It should be just as sticky (or non-sticky) as normal matter. Here’s how we know. Not only here on Earth, but everywhere in the Universe that we look, we find structures […]
A mysterious startup reveals a groundbreaking solar energy achievement.
One of NASA’s original great observatories, Spitzer showed us the infrared Universe as never before. On January 30, 2020, NASA’s Spitzer Space Telescope was retired after a 17 year mission. Prior […]
After the Big Bang, merging supermassive black holes are unparalleled. Here’s how we’ll find the first one. Last week, NASA’s Chandra X-ray observatory made history by announcing the most energetic explosive […]
Bastet was the daughter of the sun. The ancient Egyptian goddess was originally a fierce lioness warrior—a strong woman with the head of a big cat. Over time, her image […]
It really is the ‘glue’ that holds the Universe together, enabling structures like our own galaxy to form in the first place. One of the most puzzling and counterintuitive facts about […]
The Leonid meteor shower peaks today. Its parent comet taught us where meteor showers come from. Every year, as Earth regularly orbits the Sun, meteor showers repeatedly recur. While August’s Perseids […]
Only one dark matter detection experiment ever gave a positive result, in conflict with all the others. This could be why. For multiple generations now, it’s been apparent to astronomers that […]
Spiders, fish, birds, and bats all break with their daily routines.
Ever wondered why the longest day of the year happens when it does?
Without this one ingredient, there wouldn’t be enough ‘glue’ to hold the Universe together. Of all the things in the Universe to be thankful for — the stars, planets, atoms, molecules, and […]
The total solar eclipse of July 2, 2019, is the longest one we’ll have until 2027. And that’s not all. On July 2, 2019, the new Moon will pass between Earth […]
It’s perhaps the most famous equation of all, with lessons about reality for every one of us. If you’ve ever heard of Albert Einstein, chances are you know at least one […]
The TESS satellite captures rare images of a cataclysmic event in a faraway galaxy.
