Red dwarf stars were supposed to be inhospitable. But TOI-700, now with at least two potentially habitable worlds, is quite the exception.

For well over a century, engineers have proposed harnessing the ocean’s tides for energy. But the idea hasn’t seemed to register in many places.
Astronomers have discovered more than 5,000 confirmed exoplanets — very few of which resemble Earth.
Even at its faintest, Venus always outshines every other star and planet that’s visible from Earth, and then some!
Like humans, stars die. The James Webb Space Telescope’s early images already give us a lot of information about how this happens.
At 1,600 light years away, the black hole is practically in our cosmic backyard.
NASA has finally chosen which flagship mission, like Hubble and JWST, will launch in ~2040. Detecting alien life is now a reachable goal.
In our Universe, all stable atomic nuclei have protons in them; there’s no stable “neutronium” at all. But what’s the reason why?
As we look to larger cosmic scales, we get a broader view of the expansive cosmic forest, eventually revealing the grandest views of all.
In Sun-like stars, hydrogen gets fused into helium. In the Big Bang, hydrogen fusion also makes helium. But they aren’t close to the same.
Invisible cloaks. Ghost imaging. Scientists are manipulating light in ways that were once only science fiction.
“Imagination is more important than knowledge” is often taken to mean that your conceptions outweigh what’s real. That’s not what he said.
It rotates on its axis, revolves around the Sun, moves throughout the Milky Way, and gets carried by our galaxy all throughout space.
When battles raged in ancient cities, their rocks blazed so brightly that they could be reoriented according to Earth’s magnetic field.
Known as orphaned planets, rogue planets, or planets without parent stars, these “outliers” might be the most common planet of all.
How the simple act of watching twilight can radically transform our perception of the world and our role within it.
In 1920, astronomers debated the nature of the Universe. The results were meaningless until years later, when the key evidence arrived.
Really simple interventions can greatly reduce indoor temperatures during the summer, particularly in places like the Pacific Northwest.
Even though the leftover glow from the Big Bang creates a bath of radiation at only 2.725 K, some places in the Universe get even colder.
Dive into China’s profound intellectual legacy through five seminal texts that have shaped millennia of thought.
When people pick the greatest scientist of all-time, Newton and Einstein always come up. Perhaps they should name Johannes Kepler, instead.
“Superhabitable” planets might be real, but Earth is probably as good as it gets.
“I watched closely for the sun or stars to appear, to correct my chronometer, on the accuracy of which our lives and the success of the journey would depend.”
With such a vast Universe and raw ingredients that seem to be everywhere, could it really be possible that humanity is truly alone?
The laws of physics aren’t changing. But the Earth’s conditions are different than what they used to be, and so are hurricanes as a result.
The familiar terrain of solids, liquids, and gases gives way to the exotic realms of plasmas and degenerate matter.
Narnia and early Middle-earth were pancake-esque — but their creators took differing views on de-globalization.
The Universe is precisely dated at 13.8 billion years old, but astronomers claim the Methuselah star is 14.5 billion years old. What gives?
Forget about the terawatt lasers we’re making on Earth. This natural one is thousands of times more powerful than the Sun.
