Science Stuff.
As a science enthusiast I’m fascinated in what we discover and what we are yet to learn. As such I’m going to dump interesting science stories in this thread on an ongoing basis.
I’m going to provide links where I can and explanations when I think I know, but I want peeps to correct me if I get something wrong about a story or article. Yes I want to be peer reviewed!! And if there is a science topic that peaks your interest, put it in here and I’ll grab some info on it to discuss. So load up your pocket protectors and straighten your bow ties, it’s time to get all Sciencey.
To start off with we’ll look at something close by and familiar to each of us, our Sun.
Fun Sun Facts:
We use our Sun as a unit of measure = 1 AU (Astronomical Unit) is the distance from the Sun to Earth. Saturn is an average of 9.6 AU from the Sun. Old Pluto’s average distance from the sun is 39.5 AU.
Our Sun sings and breathes - https://www.nasa.gov/feature/goddard/2018/sounds-of-the-sun
Our Sun Farts - https://solarsystem.nasa.gov/resources/2288/the-solar-wind-across-our-solar-system/
Our Sun is currently converting 600 million tons of hydrogen into helium every second - https://sunearthday.nasa.gov/2007/locations/ttt_solarenergy.php
Now that sounds like a lot, but when you think our Sun is only halfway through its lifecycle and has approximately 4 billion years of fuel left to burn, than you start to understand how big it is. If you want a visual of how big compared to Earth, check out the pic below.
The material of the Sun is so compressed and so dense, it takes a particle of light 3 million years to get from the core where it’s created to the surface of the Sun itself and then only 8 mins to reach Earth.
And yes our Sun does have a name, Sol. This name originates from the ancient Roman’s god of the Sun, Sol. This alternate name is where we get the term “solar system,” which literally means system of the Sun.
Inevitably our Sun will die and use up all its hydrogen fuel. When that happens it will grow into a Red Giant and consume Mercury, Venus and Earth as its outer layers expand to the reach and melt Mars. That will be the end of all the inner rocky planets of our Solar System and the outer gas giants will be stripped of their upper clouds and reduced to roughly 10-30% of their current size due to the increase in the power of the solar winds (farts). And when that expansion part of our Sun’s lifecycle is compete and it shrinks back to become a White Dwarf Star, our Solar System will be unrecognisable. Our Sun will then spend the rest of its 100billion year existence faintly flickering as part of the ocean of White Dwarfs that currently inhabit our Galaxy.
