Galaxy Lenses Galaxy from Webb

Is this one galaxy or two? Although it looks like one, the answer is two. One path to this happening is when a small galaxy collides with a larger galaxy and ends up in the center. But in the featured image, something more rare is going on. Here, the central light-colored elliptical galaxy is much closer than the blue and red-colored spiral galaxy that surrounds it.

This can happen when near and far galaxies are exactly aligned, causing the gravity of the near galaxy to pull the light from the far galaxy around it in an effect called gravitational lensing. The featured galaxy double was taken by the Webb Space Telescope and shows a complete Einstein ring, with great detail visible for both galaxies. Galaxy lenses like this can reveal new information about the mass distribution of the foreground lens and the light distribution of the background source. Image Credit: ESA/Webb, NASA & CSA, G.

Image of Arp 122, also known as NGC 6040 and LEDA 59642, from the Atlas of Peculiar Galaxies by Halton Arp (1966).

In the original catalog, it was in the category: Elliptical galaxies - Close to and perturbing spiral galaxies. This pair of galaxies NGC 6040, the tilted, warped spiral galaxy and LEDA 59642, the round, face-on spiral are in the midst of a collision.

A grainy, black-and-white image of a pair of merging galaxies. One is seen face-on and is circular in shape. There is no detail in the center. The other galaxy is seen as a disk tilted away from the viewer and it is partially warped. It has a rough American football shape. Various small galaxies and stars cover the scene, seen as fuzzy white points. The background of space is black.

Milchstrasse
Aussichtspunkt Niesenbänkli in Ringoldswil um 4 Uhr morgens. Es war kalt und ich habe 2-3 Stunden an der gleichen Stelle die Milchstrasse fotografiert, wunderte mich, dass die Sicht durch die Kamera immer trüber wurde, bis ich feststellte, dass sich Raureif auf der Linse gebildet hatte.

Virgo Cluster Galaxies

This telescopic view captures the Virgo Cluster, 50 million light-years away, featuring bright elliptical galaxies M87, M86, and M84. M87 dominates with its supermassive black hole, first imaged by #Earth's Event Horizon #Telescope. Markarian's Chain is visible, including the interacting galaxies NGC 4438 and NGC 4435.

Planetary Nebula NGC 1514 from Webb

Explanation:
What happens when a star runs out of nuclear fuel? For stars like our Sun, the center condenses into a white dwarf while the outer atmosphere is expelled into space to appear as a planetary nebula. The expelled outer atmosphere of planetary nebula NGC 1514 appears to be a jumble of bubbles -- when seen in visible light. But the view from the James Webb Space Telescope in infrared, as featured here, confirms a different story: in this light the nebula shows a distinct hourglass shape, which is interpreted as a cylinder seen along a diagonal. If you look closely at the center of the nebula, you can also see a bright central star that is part of a binary system. More observations might better reveal how this nebula is evolving and how the central stars are working together to produce the interesting cylinder and bubbles observed.

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.

Explanation:
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.

Hubble and Legacy Survey image of Arp 282, also known as NGC 169 and NGC 169A.

NGC 169 (bottom) and NGC 169A (top) are interacting, creating delicate streams of stars, gas and dust that visibly link the pair.

In this image, the luminosity comes from Hubble ACS/WFC observations, and color comes from the Legacy Survey.

A large spiral galaxy is seen in the center of the frame. It's tilted at an angle, so that it's disk appears as an oval rather than a circle. Dramatic dust lanes cross in front of the center of the galaxy and are backlit by a haze of yellow-white stars. Below the spiral is a smaller disk galaxy seen in shades of blue white. It appears to be at almost a right angle to the large spiral, falling out of the larger galaxy. The two galaxies are connected by a bridge of dusty tendrils, which are also backlit by the main galaxy. This galaxy pair looks a lot more 3D than most interacting galaxies because of their angles and the backlighting effect.

Hubble Space Telescope image of Arp 147, also known as IC 298.

The clumpy, blue ring in the galaxy on the right likely formed when the companion galaxy to the left crashed through its center. This sent a pressure wave outward, like a ripple in a pond, compressing the right galaxy's gas and triggering the formation of new stars.

Two ring-like galaxies. On the left is a galaxy with a bright core surrounded by a yellow ring. There is a gap between the core and ring where the black background of space shows through. The galaxy is tilted so that the circular ring appears oval-shaped. On the right is a another circular galaxy, made mostly of a ring of bright blue dots, which are star clusters. On the bottom left part of the ring is a haze of white stars and orangish dust. The center of the ring is empty and the black background of space shows through. This galaxy looks a little like the writing of the aliens from the movie Arrival.
