The Galactic Center in Radio from MeerKAT

https://apod.nasa.gov/apod/image/2504/GCenter_MeerKatWebb_1080.jpg

What's happening at the center of our galaxy? It's hard to tell with optical telescopes since visible light is blocked by intervening interstellar dust. In other bands of light, though, such as radio, the galactic center can be imaged and shows itself to be quite an interesting and active place. The featured picture shows an image of our Milky Way's center by the MeerKAT array of 64 radio dishes in South Africa. Spanning four times the angular size of the Moon (2 degrees), the image is impressively vast, deep, and detailed. Many known sources are shown in clear detail, including many with a prefix of Sgr, since the galactic center is in the direction of the constellation Sagittarius. In our galaxy's center lies Sgr A, found here in the image center, which houses the Milky Way's central supermassive black hole. Other sources in the image are not as well understood, including the Arc, just to the left of Sgr A, and numerous filamentary threads. The inset image shows a small patch recently imaged in infrared light with the James Webb Space Telescope to investigate the effects of magnetic fields on star formation.

Are you into fishing? The "fishing rods" in this image are a tad bigger than the ones you may be used to 😉 In this image of our Extremely Large Telescope, currently under construction in #Chile, huge cranes appear to be fishing for construction materials around the telescope.

Inside the dome is the telescope's main structure, which will eventually hold the telescope's mirrors, including its huge 39-m primary mirror.

A night image of a partially-built telescope under the stars. The image uses a distorted projection, which creates a focal point in the centre which is closer to the viewer, and which everything bends around. The middle of the picture is taken up by the dome building of the ELT, with a crane on the right that extends from the bottom right of the image, curving up to the middle of the image at the top. Its tether line splits the image in half horizontally. The dome of the ELT is open, showing the beams that hold the main structure in place, around it, are the beams that will make the doors once panelling is attached to it. Above the ELT on the left is the Milky Way, extending from the horizon about a third of the way up the image, meeting the top of the crane in top middle of the image. The Milky Way looks like a blue and purple wispy cloud, with points of white, the brighter stars.

The Galactic Center in Radio from MeerKAT

MeerKAT's radio image reveals the Milky Way's center, including Sgr A with its supermassive black hole. The vast 2-degree view details many celestial features, while JWST's inset probes star formation and magnetic fields. Optical telescopes can't see this due to dust.
