Remember when 5G antennas (antennae?) spread COVID-19? Good times. Whatever happened to that theory? It had so much potential.

LEDA 1313424, nicknamed the Bullseye, has 9 rings. Hubble has confirmed 8 rings, and data from the W. M. Keck Observatory confirmed a 9th. Hubble and Keck confirmed which galaxy drove through the Bullseye, creating these rings: the blue dwarf galaxy immediately center-left.

In less than 2 months, NASA's Voyager 1 spacecraft will break the 1 light-day milestone, meaning one-way delay for radio signals between it and the Earth will be 24 hours. 49 years in the making. Hat tip to @arepublic86.bsky.social for bringing this to my attention. science.nasa.gov/mission/voya...

Jupiter - From Gordan Ugarković (ugordan.bsky.social) - flic.kr/p/BfyQX
This is currently my best guess at a true color image of Jupiter. Color balance is based on recent Earth-based views and also using Hubble images. The image was taken by Cassini on 13 November 2000 and is one of the last single-frame footprints on approach where all three approx. red, green and blue filters exist.

Narrow-angle composite taken from a distance of 44.8 million km and at a phase angle of 18 degrees.

Astrophotographer Adam (AJ) Smadi caught this image a few hours ago from Washington state. A thin crescent Moon, sunlight illuminating the rugged lunar surface. And 2,400 times farther away—and on the other side of the Sun—mighty Jupiter, and its moons Io (left) and Ganymede (right).
A crescent Moon seen during the day, arcing from upper left to lower right of the frame. At lower centre is the full disk of Jupiter; the small dots to its upper left and lower right and Io and Ganymede, respectively.

Kinda cool to be able to look out of my balcony and see the place where one of the world-famous antibiotics was first synthesized in 1980 - Azithromycin. Company had the "Pliva" logo up until a few years ago, now it's a subsidiary of Teva Pharmaceuticals. I liked the old logo more.

🆕 This NASA/ESA/CSA James Webb Space Telescope image shows planetary nebula NGC 2392, nicknamed the 'Lion Nebula'. This near- and mid-infrared composite image reveals the complex structure of the nebula 🧪🔭 esawebb.org/images/weic2... @science.esa.int @stsci.edu
Planetary nebula NGC 2392, also called the Lion Nebula, against the black background of space. The nebula is in the centre, circular in shape, and looks like a male lion’s head. In the very centre is a small, pinkish-white circle with eight-point diffraction spikes, a white dwarf star. Surrounding the star are light purple-pink cavernous bubbles and shell-like rings. The bubbles and shells collectively form an oval with two small, wide arcs near the top, reminiscent of a lion’s face and its ears. What appears to be extended outward from the lion’s face is a thick ring of purple-blue material. The width of the ring is consistent throughout and resembles a mane. The area closest to the lion’s face looks cloudy, while the edges of the mane look like there are clumps of dust with comet-like tails and strands. In the background are distant galaxies and stars. Some galaxies appear as small yellow and orange points of light and others with visible spiral structures. A couple of the stars have diffraction spikes.

These two images aren't much to look at, but I wanted to point out that Uranus and Neptune really don't look very different. It's been an accident and miscommunication/misinterpretation by the press during VGR2 flybys that Uranus was noticeably green and Neptune was dark blue. flic.kr/p/J8aWsJ

Cassini wide-angle camera RGB view of Titan in Saturn's shadow taken on 2009-11-30. A certain Dave Bowman could have made a comment about the number of stars visible. Full quality image available at flic.kr/p/8HmgV9
Extremely long, 560 second exposures in each of the 3 RGB filters were needed to catch the faint illumination of the moon with light scattered by the rings and Saturn's atmosphere. As a result, the background starfield is prominently visible as well. The stars show up as streaks because Cassini was tracking Titan the whole time.

Distance to Titan: 2.4 million km
Phase angle: 81 deg
