The TRUTHS mission aims to collect extremely precise data on how much radiation Earth absorbs and reflects.
Using permanent magnets may help to make nuclear fusion reactors simpler and more affordable.
The summer solstice is the longest day of the year, but doesn’t have the earliest sunrise or the latest sunset. Here’s why. The length of a day on planet Earth might […]
Black hole mergers are some of the most energetic events in the Universe. Could the gravitational waves they produce ever harm us? The Universe is not a static, stable place. Out […]
Need to isolate? No problem! This philosopher is keeping the world posted on his isolation routine by Facebook.
Matter can indeed sprout out of nothingness, causing the universe to expand.
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. […]
There are three things your new theory must do in order to be taken seriously as science. This one’s 0-for-3. Every once in a while, a revolutionary idea comes along that […]
CuriosityStream is a non-fiction streaming platform of over 2,000 documentary features and series that open up every facet of our planet, our times and our universe.
It’s absolutely true that atoms are mostly empty space. But removing even that empty space is impossible, and this is why. If you were to take any object in the Universe […]

The most famous ‘supernova impostor’ of all could have died back in the 1840s. Here’s what we think kept it alive. In all of astronomy, no stellar event releases more energy […]
Just because an idea is fashionable doesn’t mean it’s relevant for our Universe. One of the greatest unsolved puzzles in all of science is dark energy. The Universe isn’t just […]
We have two ways of measuring the expansion rate. Here’s the harder one. If you want to understand where our Universe came from and where it’s going, you need to measure […]
In both visible light and infrared, we get a preview of the spectacular advances that await the James Webb Space Telescope. What astronomers see isn’t just determined by the telescope […]
The world isn’t ending! But we are likely at the beginning of a profound transformation.
At the core of the largest star-forming region of the Local Group sits the biggest star we know of. Mass is the single most important astronomical property in determining the lives […]
With just a few more neutron star mergers, we’ll have the best constraints of all-time. How fast is the Universe expanding? Ever since the expanding Universe was first discovered nearly […]
Thought expriments are great tools, but do they always do what we want them to?
Doomsday prophesies have never once come to pass, but they’ve never had science on their side like this before. Every year, the Earth completes an orbital revolution around the Sun, returning […]
And one of our planets has the orbiting moons to prove it. Despite the dangers posed to planet Earth by a comet or asteroid strike, our Solar System is actually an […]
The pandemic has given us an early glimpse at how truly disruptive the fourth industrial revolution may be, and the measures we’ll need to support human dignity.
What’s more massive than the heaviest known neutron star but lighter than the lightest known black hole? LIGO may be about to solve that mystery. Whenever a star is born in […]
The Ultra-Deep and eXtreme Deep Fields have revealed the Universe as never before. Here’s what lies inside. From 2003 through 2014, NASA’s Hubble Space Telescope observed the same tiny region across […]
