Just... no.

Found this when I was searching for a simple Hertzsprung-Russell diagram.
(A "what's wrong with this picture" exercise for the astronomy fans 😊)

A fairly simple but colourful Hertzsprung-Russell diagram, showing the luminosity vs. temperature values for stars. 

The temperature scale on the bottom goes from 40000 K to around 2000K, and the axis is a thick line with the colours of a white light spectrum, violet → blue → green → yellow → orange → red. 

The locations of the various types of stars are indicated with coloured circles that follow the same colour scheme as the temperature axis. The circles are all the same size, but I'm not fussed about that.

Okay, I think I avoided spoilers - What's wrong with this picture?!

For anyone attending the WeTeach_CS 2023 summit, come hear me talk about how computer science can be integrated into physics and astronomy courses in high school. sched.co/1KcZ0 #cs4yall #computationalthinking #computerscience #physicseducation #astronomyeducation #weteachcs23

#DYK it can #rain on the #Sun? #Plasma rain occurs when large globs of super-hot gas called plasma gather in the Sun’s outer #atmosphere. When the globs of plasma become cooler and more dense than the rest of the Sun’s outer atmosphere, they drip back down on to the Sun like rain.

💢 You can't stand on Uranus

If we ever manage to travel to the gas planets, you might be in for a bit of a shock when you step off the spaceship. That’s because Jupiter, Saturn, Uranus and Neptune don’t have solid surfaces - they have a rocky core, but are mainly big balls of hydrogen and helium.

Uranus’ clouds are made up of hydrogen sulphide, meaning they have a very similar smell to rotten eggs. Gross.

Saturn's rings are 90% water

Saturn is home to the Solar System’s most epic ice rink. Being so far from the Sun, the water in its rings is frozen into ice. It is one of four planets that have rings around them - the other gas planets do too. However, the rest were undiscovered until the 1970s when probes went to explore them. Saturn’s were the first rings seen through telescopes from Earth.

As the air then descends, it becomes warmer and drier and therefore more stable. It blankets the region below and stabilizes the air contained within, causing people within that region to notice a calm before the storm.
