The Farthest Galaxy Ever Discovered

What's the most distant galaxy ever observed? 🌌

Astrophysicist Erika Hamden explains it's called MoM-z14, and its light took 13.53 billion years to reach us. But thanks to the universe's expansion, that galaxy is now a staggering 33.8 billion light years away. When the light was emitted from MoM-z14 the universe was smaller. The space between us and that galaxy has gotten stretched out so much  that it actually sits outside our observable horizon. It's a mind-bending reminder that we're seeing galaxies as they no longer even look today.

This project is part of IF/THEN®, an initiative of Lyda Hill Philanthropies.

Turn A Tea Bag Into A Hot Air Balloon

How does fire make tea bags fly? 🔥☕️

Alex Dainis demonstrates how lighting a tea bag causes the air inside to heat up, expand, and rush out. Just fold open a few empty tea bags into tubes on a baking sheet, then light the top with an adult and a fire extinguisher handy. The now-less-dense air inside sends the bag rocketing upward, similar to how a hot air balloon works, except this one's a one way trip once it burns.

4-servo quadruped robot walks upside down on a magnetic ceiling — passive magnets, no adhesion tech (open-source platform)

Turns out you don't need active adhesion (vacuum, electromagnets) for ceiling locomotion — passive permanent magnets in Quaddle open source robot's foot tips are enough, as long as the gait is designed for holding contact upside down instead of just an inverted version of the ground-walking gait.

The interesting part wasn't the magnets, it was the gait — same open source robotics platform OpenCat, same 4 servos, just a different motion profile. Planning to open source this gait's code before it ships too, so anyone curious can adapt it, not just read about it.

Anyone else working on non-standard locomotion modes (climbing, inverted, whatever) — what ended up being the hardest part for you?

NASA Set to Launch Nancy Grace Roman Telescope: Views 50x More Sky Than Hubble

We are getting closer to the launch of NASA's Nancy Grace Roman Space Telescope! 🧪

The Nancy Grace Roman Space Telescope is designed to combine the strengths of the James Webb Space Telescope and the Hubble Space Telescope. It’s going to look and live in the same space as JWST while using a Hubble-style mirror to see things completely differently. The Roman telescope will observe patches of space bigger than the full moon and will see 50 times as much space in five years as Hubble has in 30!
