Human beings have been aware of solar flares for as long as we’ve looked up at the sky. Now the ESA Solar Orbiter has discovered tiny flares from the sun that are much smaller than the solar flares we have been able to observe in the past. They’re called solar campfires, and that’s pretty cute. Here’s more from SlashGear:
The temperature of the tiny campfires reaches between 1 million and 1.6 million degrees Celsius. While they are described as tiny, they are actually between 400 and 4,000 kilometers long and extend 1000 to 5000 kilometers above the sun’s photosphere. The solar corona is extremely hot with a temperature of around 1 million degrees Celsius, while the photosphere has a temperature of about 5500 degrees Celsius.
