Supermassive black hole caught playing with its food!

The supermassive black hole at the centre of galaxy NGC 4945 is swallowing huge amounts of matter. Yet, contrary to a black hole’s all-consuming reputation, our Very Large Telescope (VLT) has caught it blowing out powerful winds of material.

This cone-shaped wind is shown in red in the inset image. In fact, the wind is moving so fast that it will end up escaping the galaxy altogether, lost to the void of intergalactic space.

A galaxy stretching across the dark, star-filled expanse of space. Beside it, an inset zooms in on the galaxy’s core, revealing clouds of gas and dust, from which a bright, red, cone-shaped structure emerges.

cafuego 🔭🤦🏼‍♂️

As we’re heading into autumn, Orion starts to set earlier every day and the center of the Milky Way doesn’t rise until the early hours.

Carina and Vela are high in the sky and the southern cross is getting up there too.

We’re past best for the Magellanic Clouds, but other circumpolar objects are now moving into prime position. There are vast clouds of dark dust in the constellations of Chamaeleon and Musca.

The former is on my todo list, but I managed to sneak in a few hours on the Dark Doodad in Musca a week ago, despite some intermittent high cloud.

This dense snake is actually shaped more like a sheet, which we’re seeing edge-on. It blocks out the light from more distant stars.

The fuzz-ball on the right is a globular cluster, which sits 16,000 light years beyond everything else in this image.

A dark worm of dust is silhouetted against a dense star field. On the right hand side sits a distant fuzz ball globular cluster. Just below the dark cloud a bright star is surrounded by a faint halo, caused by some cloud.

Herbig Haro 49/50 - NASA/ESA JWST Space Telescope

This is my interpretation of the data aligned by @Landru79

NASA/ESA JWST Space Telescope
Herbig-Haro 49/50 (protostellar jet) at 625 light-years
Time: 2024-08-06
Instruments: NIRCam, MIRI
Filters: F200W, F335M, F444W, F470N, F770W
Colours Assigned: Blue, Cyan, Green, Orange, Red
Proposal ID: 6558
PI: Macarena Garcia Marin

This is an image from the JWST Space Telescope in near infrared. Colours has been assigned to monochromatic filters. The image showcases a glowing, conical-shaped cloud of deep orange, red, and yellow gas stretches from the lower right to the upper left. This structure, known as Herbig-Haro 49/50, has a swirling, textured appearance and takes up most of the image. At its lower right end, the cloud has a rounded, translucent shape with a golden glow. Nearby, a spiral galaxy with a bright blue core fades into reddish-orange arms against the dark backdrop of space. As the cloud extends upward, it widens slightly, with red and amber hues blending into the surrounding darkness. The background is filled with bright white stars and distant galaxies in shades of white, yellow, and blue.

A while back (around seven months ago) I posted an image of ISS (first image), but captured FROM ABOVE (higher orbit). This is the work of Aussie company HEO!

This type of work is really fascinating as things (like satellites) are all moving at high velocities up there (28,000 km/h) - so other things (like other satellites or space stations) zip past quickly. You would then need to 'de-zip' the object to make a crisp clear image.

Well, they've done it again.

This time, imaging the Chinese Space Station (second image) from a distance of 83 kilometres (resolution of 0.17 m/px) 🤯

This is really cool stuff. I promise.

grainy but detailed image of the international space station, showing its large solar panels and different modules. Several spacecraft attached to the station are also annotated.
The Chinese Space Stations, showing extended modules and two long arms of solar panels (four rows in total). The image is captured from a BlackSky satellite in a higher orbit.

Updated diagram version for #SciComm usage!

Have stitched together the annotated image, along with that excellent diagram from The Planetary Society.

Someone said to me last night that this looks like a half-cut avocado, and now I cannot unsee it lolololol

Such a great image, and another fine example of how physics allows us to see around corners!

Three tile image with two images in top row. Top row: In the centre is an elliptical galaxy, seen as an oval-shaped glow around a small bright core. Around this is wrapped a broad band of light, appearing like a spiral galaxy stretched and warped into a ring, with bright blue lines drawn through it where the spiral arms have been stretched into circles. A few distant objects are visible around the ring on a black background. The image has been annotated to point out the foreground galaxy as well as the background spiral. In the bottom row: Diagram showing the JWST on one side with light being focused into it from a distant galaxy, via an intermediate galaxy. The Galaxy appears as a ring as light scattered in all directions is delivered to the focal point.

The Whirlpool Galaxy - Messier 51a + 51b

-----------------------

Capturing this beautiful all-time favorite target involved taking my big 8" RC out of the city. This time the field work was much more successfull than earlier attempts this year... there was no wind and only 1.5 of setup time.

I am glad to have captured 3 h of RGB data before the moonrise. Especially because I had to motivate myself for work the next day.

Whooooaaaa! The new #JWST image is so good! So much physics going on — physics Einstein himself thought about!

This is called an Einstein Ring. When a massive foreground galaxy (in this case, an elliptical galaxy) warps the space-time around it, light from behind it bends in our direction.

The JWST caught this fantastic example, where the background spiral galaxy is getting warped into our view. It appears as a ring, but we can see its structures like its spiral arms, gas features and star clusters.

Incredible science happening here!

I added the annotations in the second image.

In the centre is an elliptical galaxy, seen as an oval-shaped glow around a small bright core. Around this is wrapped a broad band of light, appearing like a spiral galaxy stretched and warped into a ring, with bright blue lines drawn through it where the spiral arms have been stretched into circles. A few distant objects are visible around the ring on a black background.
