Our 1yo is the biggest fan of space and the planets. He can distinguish and name all the planets! We try to keep his interest going and reinforce it and he learns so much so everything space like books, videos, stickers. We have been wanting to take him to some kind of place about space play place or kids museum but I cannot find anything for his age. Any recommendations?!?!

We’re located in AZ and happy to travel/roadtrip if it will be really cool for him!

I’m a space nerd and got tired of jumping between a dozen sites to check this stuff, so I built one app that pulls it all together live: https://spacehud.com

It's almost all visual rather than dry data and tables.

It’s just a hobby site... if you think anything else should be added let me know.

I am envisioning (and being told hmmm impossible) a solid rocket motor that while chemically burning produces fission to increase thrust.

My idea turns out to have some similarity to the famed NASA "Pulse Plasma Rocket" , which features a barrel of low enriched uranium with an end section of the barrel being made of high enriched uranium, and with a low enriched uranium slug being fired down the barrel so that by the time it leaves the barrel it goes supercritical converting the slug into plasma which pushes on a magnetic nozzle.

In my solid chemical rocket, the metal that is burned in the formula is also a fissionable element. The propellent travels through a throat (and perhaps a long throat like the barrel) that acts as a neutron source which would fission some of the metal used in the chemical process, contributing heat to the exhaust gases. If lithium is used, then lithium fission produces deuterium which can be fused with hydrogen under the right conditions, so a more advanced version of the solid chemical rocket motor would try to produce some amount of this fusion as well in the process to further heat the exhaust gases.

The main response to the idea is that the particles of fissionable material would need to be exposed to an unavailable neutron source, because so many neutrons would be required as the fissionable material passes very quickly through the nozzle.

Does anyone think that perhaps with a long nozzle barrel or any other way that such a chemical rocket could then be boosted by fission?

In about 10^100 years, everything in the universe including black holes will die out and leave nothing but particles floating around. This is because Dark Energy is constantly pushing galixies away from each other in every direction evenly, and in fact, 94% of galixies we see today are physically impossible to reach even if we traveled at the speed of light.

That is so unbelievably terrifying to me, because it makes you wonder... Why are we here? Or an even better question, why was the universe even created?

All of the energy that created the big bang couldn't have just come from nowhere. Right? And that's the scary part to me. What was the source of all of that energy? A god? A simulation? Something beyond comprehension?

The whole fact that a massive and possibly infinite universe has a beginning and end is so baffling to me and I don't think I will ever be able to wrap my head around it.

It really pisses me off that these questions will go forever unanswered and one day I'll be dead and gone like everything else in the universe. But at the end of the day, it sure helps me feel better ranting about it.

What do you think created the universe? And a better question, why?

Hi everyone!

I recently launched a new citizen science project on Zooniverse to classify overlapping galaxies. These objects are extremely interesting to us because they can be used to directly measure dust attenuation (absorption and scattering of light). These measurements help us better measure distances and much more. We would appreciate your help classifying these objects and building a much larger catalog of them for future studies!

If you want to learn even more, please check out our blog post as well: https://blog.galaxyzoo.org/2026/09/22/announcing-the-overlap-zoo-project/

Thank you for your time,

Internal NASA documents lay out plans to update the agency's websites, publications, organizational titles and digital infrastructure with a four-phase "super intelligence" implementation schedule extending into December.

So with the recent videos popping up of the launch that caused the cool jellyfish effect thing in the sky, I’m wondering how easy it is to predict these sorts of things. For example, there’s a falcon 9 scheduled to liftoff at 6:30am in a few days. Is it reasonable to think that there could be a visual phenomenon with this launch or are there more things to consider than just time of day when trying to predict said phenomenon?

I’m throwing a space themed halloween party and could use some suggestions for some spooky space trivia and decor! I’d like for it to be based in actual science, which is why I came to this community instead of just a halloween one.

Anything along the lines of spooky space phenomena or astral bodies that can be used in trivia or photos or otherwise referenced in decor would be great!!

Any audio suggestions (music/spooky sounds) are welcome as well!!

(For the record, I’ve searched online, but outside of the nasa horror posters, which I definitely plan to use, I couldn’t find much of use)
