Fusion Energy

Colorful nebula with bright stars ignite glowing gas clouds in space, featuring red, yellow, and blue hues against a dark background.
Although a star's "birth" is well-defined, it doesn't correspond to an ignition event in its core. Here's how stars are actually born.

13.8 billion years have passed since the Big Bang, but many stars will survive for longer than that. What's the longest-lived a star can be?

Tech designed to fuse atoms might be able to clean up space, too.

Scientists have been chasing the dream of harnessing the reactions that power the Sun since the dawn of the atomic era. Interest, and investment, in the carbon-free energy source is heating up.
A record-breaking nuclear fusion experiment showcases a large machine in a factory.
A massive nuclear fusion experiment just hit a major milestone, potentially putting us a little closer to a future of limitless clean energy.
A man is working on a machine in a lab, using laser technology to apply precise pressure.
Light can be turned into heat, which can then be turned into motion, and the effect of that motion can be turned into a big squeeze.
Its implications go well beyond the Earth itself, affecting even the future of space travel.
If you gave me $400 and I gave you $3.15, would you consider yourself wealthier? That's a financial analogy for the supposed fusion power "breakthrough."
A next-generation LHC++ could cost $100 billion. Here's why such a machine could end up being a massive waste of money.

Nature is a whole. The sciences should be, too.
Just because you have “star” in your name doesn’t mean you are one. When we think about the objects in our Universe, they fall into two categories: self-luminous objects, like stars, […]
