It’s one of the most enduring mysteries of the Sun: why the superheated surface of this great ball of glowing plasma is actually cooler than its outer atmosphere, called the corona. Scientists now have a new explanation for this hotly debated topic, and the answer was hidden in a strange solar phenomenon that’s never
This is what will happen when our Sun dies: First, the hydrogen-powered nuclear reactor in its center will run out of fuel. The Sun will expand into a red giant, swelling to 100 times its size and swallowing Mercury, Venus and perhaps even our own planet, along with all life as we know it.
Researchers have discovered that sun bears can precisely copy each other’s facial expressions in social situations. It’s a bigger deal than you might think, especially for scientists. When humans are in social situations, we often adjust our facial expressions in response to someone else. It’s called facial mimicry, and past a point of sufficient
For something that’s supposed to help save the planet, solar geoengineering sure has a lot of enemies. Critics warn that artificially reflecting sunlight to cool the planet could unleash drastic, unintended consequences – but a Harvard-led team of scientists insists that such fears are overblown. In a new study, researchers say spraying chemicals into
In November, Chinese researchers announced that the Experimental Advanced Superconducting Tokamak (EAST) reactor — an “artificial sun” designed to mimic the nuclear fusion process the real Sun uses to generate energy — had hit a milestone by achieving an electron temperature of 100 million degrees Celsius. Now, officials are saying they believe they’ll wrap
Our Sun can let out some solar flare rip-snorters from time to time, but it’s actually pretty quiet when compared to some other stars out there. Particularly, it seems, turbulent young stars. And astronomers have just caught one belching out a real corker. It’s called JW 566, a young star about 389 parsecs (1,269
We’ve been gazing out at the Solar System for a very long time, and by now we know, more or less, where things go. Sun, planets, asteroid belt, more planets, then millions more asteroids (we’re not really sure how many). Maybe another planet. OK, so it’s a little tricky. But a new discovery has
