NASA's Van Allen Probes A and B were two half-ton spacecraft launched in Aug 2012 to elliptical 600 x 30000 km orbits to study the radiation belts. In 2019 their perigees were lowered to 200 km so that they would eventually reenter and they were switched off. (1/n)
yep! go watch it if you haven't, folks!
excellent video! 10/10, no notes!

comprehensive answer to "Is it OK to use AI?" by @gwenvarley.bsky.social
an excellent one for students and those mired in the terminological and ethical disarray to start to think more clearly
look at the data. understand the data. learn about the instrument/telescope that got you the data
I'd avoid using it (genAI) *at all* but for those who really want to use it for research, some ground rules 👇
Em um pesquisa que fizemos no Brasil 🇧🇷, a proporção entre 🙋♂️ e 🙋♀️ na Paleontologia é igual (~50%).
Por região, no entanto, há diferenças. No Sudeste, homens são maioria, enquanto nas outras regiões, são as mulheres

got inspired by some questions from phd students the other day — and also really irritated by senior academics who seem to refuse to get the issues and continue to blame students; hope useful for you! 🩷

yep! like Qualis was 😂
and don't get me started on folks that say that passive voice is the norm (there's *nothing* there about this) 😂 (or 😭?)
parabéns!!
Isso já era uma idiotice com sistemas deterministicos baseados em lógica (mesmo que de software livre, feitos e hospedados no Brasil).
É ainda mais idiota com IA
It's not "can 'AI's create software" but "are we willing to accept worse software running more and more of our lives?"
gostei da ideia, acho que vou adorar algo nessa linha.
okay, Ill bite.
What do you think the point of reading for and writing a literature review is? The process of reading and writing is crucial for THINKING. Your ideas are shaped by all of this, offloading it to gAI, no matter how "good" you think gAI is at it defeats the purpose entirely.

Woah! Stunning prominence lifting off the Sun’s northern limb. Spectacular eruption. No impacts to Earth anticipated.

"Fundamental science is a long game, and government departments and agencies can sponsor long-term projects, whether the goal is mapping the entire U.S. coastline or the entire human genome." Or building an advanced space telescope 🔭 to find out if humanity is truly alone in the cosmos.
I want to repeat comments I already made on this plot since some news outlets seem to ignore them: Hubble will not reenter until early 2030s. The curve here is alarming, but will flatten out as we hit solar minimum in the coming years. I still think it's time for NASA to take action on a reboost.
👇 not only in the US.
É isso. Mesmo a visibilidade é questionável, porque muitas áreas tem repositórios como arxiv, biorxiv etc de livre acesso (sei que muitas áreas não tem isso!).
cheio de Diamond Open Access mas temos que correr atrás do fator de impacto, jogando dinheiro pra publisher, por causa de avaliação. E faltando bolsas. Difícil, né.
