Red nugget

Imagine a star that's smaller than a planet, but hotter than the surface of the Sun! That's a Red nugget. These special stars are like the leftover cores of stars that used to be much bigger. They've used up most of their fuel and are now shrinking down. Even though they're small, they glow super bright because they are so hot. Think of a tiny ember that still gives off a lot of heat and light!

Red nuggets are born when stars like our Sun get very old. After a star has shined for billions of years, it starts to run out of its special star fuel. It puffs up into a red giant, and then it sheds its outer layers. What's left behind is the hot, dense core, which is the Red nugget! It's like the last little bit of a campfire that keeps glowing after the big flames have gone out.

These tiny stars are super important for scientists who study how stars live and die. By looking at Red nuggets, astronomers can learn about the past of stars and what will happen to them in the future. They are like clues from the universe that help us understand the big cosmic story.

Plus, they are incredibly hot, with surface temperatures that can be hotter than many other stars, even though they are so small!

The biggest superpower of a Red nugget is its incredible density. It's packed super tight! Imagine squeezing the entire Earth into the size of a sugar cube – that's how dense a Red nugget is.

This extreme density makes them very interesting to study. They are also very hot, with temperatures that can reach up to 100,000 degrees Celsius (180,000 degrees Fahrenheit), which is way hotter than our Sun's surface!
