Illustration of quantum tunnelling if it existed in the macroscopic world. Left image shows a child throwing a ball that bounces off a wall. Right image shows a child throwing a ball and it going through the wall and out the other side.

Learning about quantum tunnelling was one of the goosebumps moments that made me continue studying #physics.
From "How can this be possible!?" to "This is already used in all computers" in an hour :)

A 5 (across) 10 (down) grid of images. Each one shows a radio galaxy from the ASKAP VAST survey. The colour scale ranges from dark blue to bright yellow.
When we search for radio transients we exclude extended objects
Hence we discard lots of radio galaxies, like the ones in this ASKAP VAST gallery, compiled by PhD student Surabhi Chandra
Each image shows radio emission from a galaxy with a supermassive black hole at the centre

The Astrosky Ecosystem - Open Collective
We're building an open-source ecosystem of social media tools for the space science & astronomy communities.
For the last two years, I've been paying for the Astronomy feeds hosting myself.
It has been a privilege to grow our community here, but I also shouldn't keep doing it for free π
That's why I'm delighted to announce that we now have a donations page on Open Collective! πβοΈ #astrophotography

Farewell to an Icon: The Legacy of Molonglo Telescope
You can read about the farewell here (article by @funfactscience.com)

Molonglo leaves an incredible legacy, not just of science, but training many well known #RadioAstronomy scientists around the world.

Four pictures of the Molonglo Telescope site, from a Ray White real estate advert. The main top image shows the telescope infrastructure, extending out across farming land.

Don't worry, we stopped scientific operations a few years ago and gave it a suitable farewell (see next post).

Participation in Australian high school #Physics is declining!
The proportion of Yr 12 students studying physics fell from 14.9% in 2015 to 12.1% in 2023; gender ratio unchanged.
(Luckily this hasn't impacted the number of students studying Physics @sydney.edu.au, but it is a broader issue).

Writers/bloggers: What's your preferred platform (or which should I avoid)? I like/want:
* Minimalist style
* Impact but not monetization
* Tech-savvy but want to spend time on writing, not tech
* Writing, not videos :)
What are your favourite science/academic blogs?
