Josh Universe :goldverify:The Galactic Center in Radio from MeerKAT <a href="https://apod.nasa.gov/apod/image/2504/GCenter_MeerKatWebb_1080.jpg" rel="nofollow noopener noreferrer" target="_blank">https://apod.nasa.gov/apod/image/2504/GCenter_MeerKatWebb_1080.jpg</a> 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.

I'm thinking of getting my first scope (well, second, got a refractor 80/400 and loved watching the skies it so much I returned it and am now looking for a better one 😁)what put me off the refractor was mainly chromatic aberration around Jupiter made it look like just a bright dot, no details.So now I'm figuring what to upgrade to. my options are: 1. 102/660 refractor by Omegon. My understanding is that since this is a longer focus/slower at F6.5 it will have reduced CA issues. 2. 120/600 refractor by Sky-Watcher. I've only read great things of this scope, CA will be present but I understand I can down-stop by using a cover in the lens to reduce CA. 3. 127/1500 Matsukov by SkyWatcher. Maks are great for planetary, meh for deep space. Also it costs 2x what #1 doesWhat would yall advise?

ESOAre 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 <a href="https://astrodon.social/tags/Chile" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Chile</a>, 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.Learn more about the ELT here: <a href="https://www.eso.org/public/images/potw2515a/" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://www.eso.org/public/images/potw2515a/</a>📷 ESO<a href="https://astrodon.social/tags/astrodon" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#astrodon</a> <a href="https://astrodon.social/tags/astronomy" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#astronomy</a> <a href="https://astrodon.social/tags/astrophotography" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#astrophotography</a> <a href="https://astrodon.social/tags/space" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#space</a> <a href="https://astrodon.social/tags/science" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#science</a>
