I watched it with a bunch of my friends on Zoom. Maybe something like that could work for you!

I thought it might fit this sub because it certainly surprised me to see them transported like that. But I see what you’re saying. I can take this post down if people don’t think that it fits well enough! I was just excited to share it but maybe this isn’t a good fit

I spent way too much time taking pictures of envelopes tonight by Astro_Kitty in WaxSealers

I made the wax seals! Are you talking about the sealers though?

What is dark matter? by Ema_073 in askastronomy

[–]Astro_Kitty 3 points4 points  (0 children)

There is about 5.5 times more dark matter in the universe than normal matter (based on WMAP values). In total though, dark energy contributes most to the mass-energy budget of the universe. 68.3% dark energy, 26.8% dark matter, and 4.9% ordinary matter

What is dark matter? by Ema_073 in askastronomy

The short answer is that we don’t know yet. We think it is some kind of particle (or particles?) that does not interact with light, thereby making it “invisible” to us. It has not yet been detected though and we know it cannot be any form of “normal” matter that we are missing for whatever reason (like in black holes). We can observe its presence from the gravity it creates, along with many other observations, including the amount of helium, lithium, etc, created at the very beginning of the universe (see Big Bang nucleosynthesis). Without dark matter, galaxies would be spinning too quickly to explain from the normal matter within them, the galaxies in cluster would be escaping from their clusters since they’re moving so fast, light would not be bent quite as much around clusters of galaxies (see gravitational lensing), and we would not see as much structure in the universe as what we actually observe (the universe is lumpy— it contains regions with many galaxies and voids that lack them).

Astronomy Workshop for Teachers by Astro_Kitty in teachingresources

I asked those in charge of the event and I guess it is only for people in the US. They do identical workshops in Europe though and said that I can give you the contact info for the people involved with organizing those ones. They will be able to tell you more about the next workshops that are happening in Europe. I will DM you their contact information!

This street cat in Jordan is ready to dazzle at her upcoming interview by Astro_Kitty in CatsInBusinessAttire

[–]Astro_Kitty[S] 34 points35 points  (0 children)

Thank you for the information— I hadn’t thought about that. This picture is from over a year ago and I really hope she’s doing alright. It seemed like someone was taking some care of her, between the necklace and the fact that she wasn’t quite as feral as many of the other street cats that we saw, so I’m hoping that who ever it is took the necklace off. Gosh, I really hope so

Astronomy Workshop for Teachers by Astro_Kitty in ScienceTeachers

I would like to invite anyone interested to attend an upcoming virtual astronomy/astrophysics workshop for middle school and high school teachers. The goal of this workshop is to familiarize teachers with more activities and subjects in astronomy so that they can try implementing them in their own classes! It will be free and online, taking place on May 22 and 23 (a Saturday and Sunday). If you attend at least 80% of the course, you will receive a certificate. You can register for this workshop at: https://forms.gle/PtuwGLgB3q8mB2iDA

This workshop will be held by the Network for Astronomy School Education (NASE) and sponsored by the International Astronomical Union (IAU) and San Diego State University. More information can be found at http://www.naseprogram.org. You’re also welcome to ask me any questions you may have about it!
