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... 🧪 🔭

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

Seeing a signal in different kinds of light is like having a text written in several forms of writing – it makes it easier to decipher.

In today’s issue of Astronomy & Geophysics, the Royal Astronomical Society share the story of accidentally discovering a lost photograph of Carrington – bringing to light the only known photograph of the most iconic figure in solar astrophysics.

BREAKING: This is Richard Carrington, the first person to document solar flares on the Sun & suggest their influence on aurora at Earth. The largest solar storm on record, the Carrington Event, bares his name. But, there has been no photograph available of Carrington – until now!

"While almost everything that astronomers study occurs in the vacuum of space, astronomy itself does not 'happen in a vacuum'. Interactions between scientists, as well as outreach to members of the public, improve extensively from access to good communication tools." Paper day! ⤵️

The night sky looks steady. It's not. 💥 In the night sky, asteroids drift. Stars pulse and flicker. Distant galaxies flare when something dramatic like a supernova is happening inside them. The Universe is constantly changing, even when our eyes can’t see it. 🔭🧪☄️

@scixcommunity.bsky.social - I find the search results and private library fonts small and faded compared to ADS (see screenshots). Is it possible for the user to change these? The current results are not easy to read comfortably - higher contrast defaults would be more accessible.

Sometimes when I'm quickly checking whether someone in my team has classified a #RadioAstronomy source correctly, I paste the coordinates into the Aladin Sky Atlas , and confirm... Yes, it is a star! Such a great #AstroSci tool :) (aladin.cds.unistra.fr)
