The Tails Of Comet NEOWISE!! Comet’s Usually Have 2 Tails That Always Point Away From The Sun.

The tails of Comet NEOWISE!! Comet’s usually have 2 tails that always point away from the Sun.

Here, NEOWISE’s blue ion tail on the left points directly away from the Sun and is pushed out by the flowing and charged solar wind. Structure in the ion tail comes from different rates of expelled blue-glowing ions from the comet's nucleus, as well as the always changing structure of our Sun's wind.

The other tail, the dust tail, is pushed out by sunlight, but curves towards its orbital path as heavier dust particles are better able to resist this light pressure. Comet NEOWISE's (Comet C/2020 F3) impressive dust-tail striations are not fully understood, as yet, but likely related to rotating streams of sun-reflecting grit liberated by melting ice on its 5-kilometer wide nucleus.

Important things I learned while studying Astrophysics

During presentations, 90% of the people won’t know anything about your topic, no one will notice minor mistakes

During presentations, 75% of the people won’t even listen to you

Don’t compare yourself to others. There will always be someone smarter than you, and the people you think of as smart, think of themselves as really dumb

The profs, the TAs and everyone else is also just a human. They are not perfect and have other things to do than run after and care for you.

Take care of your own shit. Always

If you work in groups, don’t be selfish. Just because you think you dont need to hand in that last paper because your grade is secure anyway, it does not mean that the others feel the same. Dont pull them down because you are lazy

If it seems too easy, you’re doing it wrong

Just because a person seems to sound convincing, check their data, they’ve usually ignored gravity or temperatures

Knowing professors personally can be both good and bad, good when it comes to jobs and favours, bad when it comes to oral exams

Buying books is useless when you can just get them from the library and sit on them for a year. Especially when there are no textbooks, but only specific literature costing around 600 € per book

Reading papers is the way to go. Always.

When showing your work/thesis, try to explain the process as simple as possible, while at the same time make your work look as hard and complicated as possible (Quote from a guy I work with: “It looks too easy for the public!”)

Learn how to work with others. You won’t get far on your own.

If English is not your native language, learn it! You will need it

Your humour will consist of science jokes and math references. Good luck making friends in the real world

literally though if you feel like your life is slipping through your fingers and every day goes too fast… try doing hard things, not just taking the easy route, like reading and making art and exercising and cooking a meal from scratch and journaling, doing these things without distraction, without being absorbed on a screen… the time will stretch and you’ll be reminded that life is long and beautiful if you make it so.

December

fairy lights and holiday displays

neatly wrapped presents with elegant bows

the smell of pine trees

hot chocolate

mulled wine in paper cups

sucking on candy cane til it gets sharp

dark chocolate truffles

sliding on polished floors

long dresses and tailored suits

iron candelabra

the church choir

stained glass windows

listening in on family affairs

peppermint chocolate

garland wrapped around the banister

sitting in the dark with just the glow of the Christmas tree

the moon in the sky like a claw

cushions and throw blankets

your favorite sweater

dog-eared pages of a classic book

Did I daydream this, or was there a website for writers with like. A ridiculous quantity of descriptive aid. Like I remember clicking on " inside a cinema " or something like that. Then, BAM. Here's a list of smell and sounds. I can't remember it for the life of me, but if someone else can, help a bitch out <3
