Euclid finds complete Einstein Ring in NGC galaxy (euclid-ec.org)
Gravitational lenses are rare in the sky – galaxies bending the light-paths of light from other galaxies behind them to form distorted or even multiple images. Even rarer is a perfect alignment of the two galaxies with us, the obervers, with the light being bent into a so-called Einstein Ring. And the rarest case was now observed by Euclid: this happening in an extremely nearby NGC galaxy.

What we know about the Milky Way thanks to Gaia (adastraspace.com)
The Milky Way is weird. I mean, really all of space is weird, that’s why I like it so much, but the more we learn about the Milky Way, the more we realize just how strange and wondrous it is. For example, did you know we live in a giant cannibal?? And that there are GHOST SPIRAL ARMS haunting our galaxy???

Largest ever photomosaic of Andromeda galaxy from NASA's Hubble (nasa.gov)
In the years following the launch of NASA's Hubble Space Telescope, astronomers have tallied over 1 trillion galaxies in the universe. But only one galaxy stands out as the most important nearby stellar island to our Milky Way — the magnificent Andromeda galaxy (Messier 31).

Hats Off to NASA's Webb: Sombrero Galaxy Dazzles in New Image (webbtelescope.org)
In a new image from NASA’s James Webb Space Telescope, a galaxy named for its resemblance to a broad-brimmed Mexican hat appears more like an archery target.

The first close-up picture of a star outside our own galaxy (eso.org)
This is an image of the star WOH G64, taken by the GRAVITY instrument on the European Southern Observatory’s Very Large Telescope Interferometer (ESO’s VLTI). This is the first close-up picture of a star outside our own galaxy, the Milky Way. The star is located in the Large Magellanic Cloud, over 160 000 light-years away. The bright oval at the centre of this image is a dusty cocoon that enshrouds the star.

New JWST image may show first-ever brown dwarfs seen in another galaxy (beehiiv.com)
I am continually amazed at what the huge infrared space-based observatory JWST can do. I mean, I know its capabilities, and I know it has a huge mirror and fantastic ability to detect faint objects and see in incredible detail. I worked on Hubble long enough to know what these beasts can do!
