From a desert oasis to the Rocky Mountains, being filled with awe makes me a better scientist.
Because of dark energy, distant objects speed away from us faster and faster as time goes on. How long before every galaxy is out of reach?
When the Hubble Space Telescope first launched in 1990, there was so much we didn’t know. Here’s how far we’ve come.
Dr. Tyson explains where we might find aliens, why “dark matter” is a misleading term, and why you can blame physics for your favorite team’s loss.
The Universe begins with negligible amounts of angular momentum, which is always conserved. So why do planets, stars, and galaxies all spin?
This company uses thousands of mirrors, AI, and machine learning to unlock the power of the sun.

Although the Big Bang occurred at an instant in time long ago, we still see the light from it. Will the evidence ever disappear completely?
The most celebrated genius in human history didn’t just revolutionize physics, but taught many valuable lessons about living a better life.
Every December, the Geminid meteor shower reaches its peak. Its 2021 show will be spectacular, but only if you do it right.
Plants at room temperature show properties we had only seen near absolute zero.
50% of stars are in Sun-like ‘singlet’ systems. The planetary nebulae we see just don’t line up. Around 7 billion years from now, our Sun’s life will end. As the Sun […]
The long-standing debate over whether dinosaurs were more like birds or lizards is drawing to a close.
Today, it’s common knowledge, but it took scientists centuries to figure out.
Over 50 years since humans last walked on the Moon, astronaut footprints and rover tracks are still visible. But they won’t last forever.
High-frequency oscillations that ripple through our brains may generate memory and conscious experience.
Researchers speculate the famous monument was one of the world’s first solar calendars, possibly inspired by trade with ancient Egyptians.
Centuries ago, the plague forced people into quarantine for years. Isaac Newton and Galileo used the time to revolutionize the world.
The classic picture of Jupiter’s great rocky core might be entirely wrong.
This storm rained electrons, shifted energy from the sun’s rays to the magnetosphere, and went unnoticed for a long time.
From how life emerged on Earth to why we dream, these unanswered questions continue to perplex scientists.
Yes, the Universe is expanding, but you might wonder, “How fast is it expanding?”
In the infant Universe, particle physics reigned supreme.
The highest-energy particles could be a sign of new, unexpected physics. But the simplest, most mundane explanation is particularly iron-ic.
The pseudoscience phrenology swept the popular imagination, and its practitioners made a mint preying on prejudices, gullibility, and misinformation.
The story of how Jupiter, Saturn, Uranus and Neptune were made isn’t a universal one. Some gas giants were built different.
The big question isn’t whether the Universe is expanding at 67 or 73 km/s/Mpc. It’s why different methods yield such different answers.
Media provocateurs and conspiracy theorists insist that they’re “just asking questions.” No, they aren’t.
The Copernican principle states that Earth is an ordinary planet, but that does not mean that life is ordinary in the universe.
There are ~400 billion stars in the Milky Way, and ~2 trillion galaxies in the visible Universe. But what if we aren’t typical?
