We've seen tons of stuff about gravitational lensing since the release of the JWST images. But, how does it work? Get a better idea of it in my latest video!

- The image taken by the JWST compared to one taken by Hubble, of the galaxy cluster SMACS 0723. It's s a gravitational lens, showing us the light of galaxies that are far behind the cluster in arcs around it. I tried to orient them the same. LOOK AT THE DIFFERENCE.
- If you touch two CLEAN blocks of the same metal together in space, they weld! Atoms in solid metals move a bit. Touch two clean surfaces together, and the atoms can't tell they're in different blocks so they become one group of atoms, ie ONE SOLID. (Gif: homemadetools.net/forum/cold-wel…)
GIF - What. The actual. F*ck. This man was tasered after stabbing a woman. Stabbing. A. Woman. And *this* is the headline they use. This, people, is what white male privilege looks like.This post is unavailable.
- Let's talk the so-called need to "get women interested in science". The thing is: we *are* interested (HELLO 🙋♀️). We're everywhere. That isn't the problem. The problem is *keeping us here*. Creating a safe environment for women, esp. women of color, is the problem.
- Mimi Aung is EVERYONE TODAY!! She tears up in-case-of-failure plan because IT'S A SUCCESS: "We can now say that human beings have flown a rotorcraft on another planet" 😭❤ History has been made, everyone!
00:00 - Tomorrow we land a rover on another planet. It's carrying an experiment that'll produce oxygen from the carbon dioxide FOR FUTURE ASTRONAUTS TO BREATHE AND USE AS FUEL TO RETURN. It cannot be overstated how incredible this is: It's A MISSION FOR THE FUTURE OF SPACE EXPLORATION.
GIF - Hi everyone I know some men think this is cool to say to a woman but it isn't, it's actually an insult. "Beauty" is subjective, and by saying this you imply that astrophysics and beauty cannot go together. This is wrong and perpetuates stereotypes. Please don't do this.
- OMG I'm a PhD candidate everyone, I DID IT!!!!
- We've detected a Gravitational Wave Background (GWB). Gravitational waves are formed from some of the most energetic processes in the Universe, like black hole mergers, or inflation! So, what does the GWB mean? (GIF source: einstein-online.info) 1/n
GIF - The Nobel Prize in Physics awarded was very well-deserved. However, next time you hear Vera Rubin didn't win for discovering dark matter bc *insert excuse here*, let today show exactly why she didn't win for discovering one of cosmology's most pressing questions: she was a woman.
- In case you were wondering how the world reduces the contributions of women, "and wife" LITERALLY IN A HEADLINE IN 2019.
