Vela Supernova Remnant taken on February 6 2021 by jeff2011 on Astrobin
The supernova remnant resides within the Vela constellation, having exploded over ten thousand years ago. It is the closes supernova remnant to Earth. Observational data from this remnant provided proof that supernova’s can produce neutron stars.
Supernovas occur at the end of a star’s life. Stars with mass over eight solar masses finish burning the hydrogen in their core and become a red supergiant. Successive fusion then occurs until the core contains iron. Fusion can no longer occur at iron since it is not energetically favorable. Gravity then takes over leading to a supernova explosion— expelling a huge amount of stellar material.
Neutron stars can form as a result of this, as protons and electrons collide to combine into neutrons. The neutron stars are stable by neutron degeneracy pressure. This pressure is caused the Pauli Exclusion principal which prevents neutrons from having the same positions.

Today was not a good day for me unfortunately!
I think I’m emotionally exhausted! I’ll be taking a break soon u guys ! My eyes won’t literally stop twitching from stress..
physics feels so inaccessible.
like what do you mean the only information on this topic is a power point presentation from ten years ago with only half of the information on it?
or you tell me there's three ways to download the software i need for the calculations, but only one of the ways actually works and you don't even tell me how to do it!!!
never mind the sheer amount of prerequisites. i never struggled with math too much, but i also never took the opportunity to skip a level in math. when i was starting out, you can't do anything without trig. so then i went and learned trig on my own, but then i needed matrices. so i went and i learned matrices and vectors on my own, but now i need calculus. and holy shit is there a lot of stuff within calculus.
half the important papers are hidden behind paywalls and the diagrams are so confusing they take me forever to figure out. maybe i'm just inexperienced, but isn't the whole point of diagrams for the information to be more accessible?????
i might be wrong since i'm young and inexperienced, but it seems as if there's this tone of exclusivity in physics. why is it so hard to find mentors, and when i do, they have such trouble believing in me? i might be young, but i can still understand and help with something. why would you ignore all my emails and just tell me to take the easy way out? i'm in it for the long run.
Astronomers are the funniest people on earth actually

why are there so many variables in physics? it’s like reading a whole new language and i’m dying here 😭
28/jan/2025, tuesday
tiring day as usual but i pushed through!!
woke up at 6 (maybe i should try not falling asleep for hours after skl if that results with me waking up early without any alarm despite going to bed past 1 a.m.)
light stretching + exercise
did ok on the eng group presentation in school today but at least it's done
searched for poetry contest
physics lab record
duolingo lesson
practiced playing keyboard
there's always all these trackers and calendars online that are supposed to "increase your productivity" "help you be more efficient" blah blah blah
sometimes you just got to write it down on a piece of paper and take it one step at a time.
i dont know if this is just the monkey brain inside of me but after a couple weeks of trying a new planning or scheduling hack, it just stops working. i feel like it's really difficult to just sit down and get stuff done especially at the times i dictate it.
i just want to go with the flow
International Space Station transit of the Moon taken by Quinn Groessl on January 31 2023.
The ISS orbits the Earth at a typical velocity of 28000 km/h (very fast) and at a typical altitude of 400 km. Gravitational forces keep the ISS in constant freefall, but with the forward velocity of the ISS, the overall distance to Earth and velocity stays pretty much the same.
These transits are pretty infrequent. The angle of the moon from the orbital plane can vary over time, and any small changes in the ISS orbit can have major effects on its path. In the sky, they are both fairly small objects, leading to smaller probabilities as well.
An important factor that allows these events to occur is that the ISS is traveling much faster relative to our perspective on Earth compared to the moon. The ISS orbits the Earth around 16 times a day, while the moon takes around a month (27.3 days).
You can see the video of it at this link. It's incredible how precise astronomers have to be with how short of a timespan there is to record this.

long study day at the library! there was a lot of snacks since it’s finals week but getting a spot was so impossible 😦 my friend and I saw three people leaving from behind some bookshelves and it was like the hunger games trying to grab our stuff and get seats before anybody else could take them
the library closed kind of early so now I’m back home and I have a long night ahead of me
- analysis study sheets (5/5)
- extra credit poem
- email people back 😭
- comp sci practice tests
- chem study sheets???
