New images of the Sun so detailed you can almost see its face! Textbook Kelvin–Helmholtz instability patterns in images with resolution of ~20 km. With quotes from @manicule.bsky.social and @hannahschunker.bsky.social www.abc.net.au/news/science... ☄️ ⚛️ 🔭 🧪
We've never seen the Sun in this much detail before
The highest-resolution imagery of the Sun's surface ever taken reveals dizzying currents, and clues about our star's magnetic fields.

Using the NSF Very Large Array, astronomers detected polarized light from a gamma-ray burst (GRB) afterglow + Faraday rotation in a GRB (a phenomenon in which magnetic fields cause the polarization of light to twist as it travels through space) for the first time at radio wavelengths! #RadioAstro

Astronomers turned to public crowdsourcing to help them find brown dwarfs in space. It, um, worked. REALLY well. badastronomy.beehiiv.com/p/citizen-sc... 🧪 🔭
Citizen scientists find over 3,000 nearby brown dwarfs
No kidding, that’s a lot of brown dwarfs

We've discovered another long period transient with ASKAP! Source #15 in this small but growing population. It repeats every 36 minutes, but despite many observations (see plot) we're not sure what it is. New paper by Joshua Pritchard: doi.org/10.1017/pasa... #radioastro
