hi are you really an astrophysicist can you tell me like your favorite facts. not in like a quiz way i just think it's a neat field. thank you !

everyone knows about how interstellar paid for simulation on what a black hole would look like but few people know how the hair animation on tangled later got used for simulations of magnetic field lines in the sun. the problem with magnetic field lines in the sun is, imagine a magnetic, which is a nice shape. now set it on fire and melt it and put it in a blender. and that's a little bit like the sun.

this was presaged some decades ago by a physicist using skills to draw simulations of magnetic field lines using the skills in drawing hair that he learned sketching models at the local nudie bar.

The first JWST image is creating quite a buzz around gravitational lensing because of the sheer amount of it in the image. Gravitational lensing makes galaxies appear warped like these:

A very small section from Webb's first Deep Space. The background is black space and a few galaxies and stars are scattered across it. The focus is on a red-orange galaxy that is warped and appears to stretch down in an arc which then stretches into a mirror image of the same galaxy.
A very small section from Webb's first Deep Space. The background is black space and a few galaxies are scattered across it. The focus is on a yellow-orange galaxy that is warped. It is elongated, bulbous on both ends and squeezed in the middle. The squeezed part arcs around a large, white spot.

Because spacetime curves around a massive body, light bends when it's near enough a massive object, allowing us to see very distant galaxies behind the cluster we're looking at.

An illustration on a black background. Around halfway it is divided horizontally. The lower half is a blue grid with straight lines except for the center, where it appears like fabric being weighed down. In this spot a couple of white dots represent a galaxy cluster. To the left of that and slighty up so it sits above the horizontal line is a white swirl representing a galaxy. Towards the right of the cluster and slightly down (but not weighing down the grid) is a circle representing Earth. Several white lines are drawn from the galaxy on the far left in the direction of the Earth. They represent disoriented light rays and are slightly bent around the galaxy cluster. Two red lines are bent around the galaxy cluster and meet again on the other side hitting Earth. Where the red lines are at the same level with the galaxy cluster they are labelled "lensed galaxy images". The graphic represents light rays from a distant galaxy being bent around a galaxy cluster due to its massive gravity which bends space time and some of those light rays being bent just the right way to reach Earth, creating a distorted image of the galaxy behind the cluster.

Here is some recommended reading on it if you wanna learn more:

Comparing the rotations of objects in the Solar System. Just look at them lol.✨🪐

To everyone that's confused, the planet Venus rotates very very slowly, with a single revolution taking about 243 Earth days, and Mercury rotates slowly, but not as slow as Venus.

The Two Stars In The Wolf-Rayet 140 Binary System Produce Shells Of Dust Every Eight Years, As Seen In

The two stars in the Wolf-Rayet 140 binary system produce shells of dust every eight years, as seen in this JWST image.

“Each ring was created when the stars came close together and their stellar winds collided, compressing the gas and forming dust.”

if you ever feel like you're not "smart enough" for STEM or didn't do that great in school, i just wanna let you know that i failed algebra 2 THREE TIMES and dropped my high school physics class the FIRST WEEK...

and NASA chose me to student research with them.

so what i'm trying to say is that STEM is for EVERYONE. if school wasn't the easiest for you and you're not the strongest in math, don't let that stop you from pursuing STEM. working hard for goals makes you a great scientist.

screw that stereotype that all STEM majors are geniuses who were building robots and knew how to work a microscope at 3 years old.

STEM IS FOR EVERYONE! BECOME A FREAKING SCIENTIST! YOU CAN DO IT!

Black hole physicists annoy me so much. They could literally say anything about what happens in a black hole and there is no good way of proving otherwise. They literally just play around with maths and make stuff up. "if you go through the ring singularity, you might come out elsewhere" "where?" "idk" like get a real job Paul
