Rubin Observatory sits on its rocky summit site amid a yellow and orange sunset with purply gray clouds above. Rubin is a boot-shaped building with long white service building pointing directly toward us and angular silver dome sticking up. The Chilean mountains recede into the distance, becoming more opaque and obscured by the hazy air as distance increases. The tiny domes of the neighboring Cerro Tololo Inter-American Observatory appear on the nearest peak behind and to the right of Rubin.

Hi neighbors! 👋

Rubin features in this NOIRLab #ImageOfTheWeek, along with our neighbors at Cerro Tololo Inter-American Observatory in the background. It's no surprise that world-class conditions attract lots of telescopes! 🔭🧪

This infrared image captures the spiral galaxy NGC 1566, located in the constellation Dorado. The galaxy's swirling arms are illuminated by young, hot stars, while the central region glows with the light of older stars. The image reveals intricate details of the galaxy's structure, including dust lanes and star-forming regions. NGC 1566 is a type SBc spiral galaxy, meaning it has a prominent bar structure at its center. The galaxy is also known as the "Spanish Dancer Galaxy" due to its shape, which resembles a flamenco dancer.

Spooky view of NGC 1566.

Marc Bloch, no issue here, of course. But how about Cavailles?

Illustration of a whitish, whirlpool-like galaxy at middle of top edge, and a tadpole-shaped structure sweeps from left to right across lower half. A label pointing to the outer left of the galaxy reads “Earth.” Faint, purple haze labeled “Milky Way Halo” surrounds the galaxy and stretches to graphic’s edges. The tadpole-shaped object is the Large Magellanic Cloud, or LMC, with its own halo and streaming tail. Semi-circular, progressively darker layers of purple labeled “Large Magellanic Cloud Halo” surround the LMC, which appears roughly circular, with a central, light yellow bar. Cloud-like features sprinkled with white specks surround this bar. Trailing the LMC is a large, tail-like feature labeled “Stream.” At the bottom left corner of graphic are several small, bright points of light labeled “Quasars.” Three light blue lines point from the label “Earth” through the LMC’s halo, and to three corresponding quasars. At the bottom, right corner is the label “Artist’s Concept.”

Hubble witnessed a dwarf galaxy crashing through the Milky Way galaxy’s gaseous halo and living to tell the tale … though a bit worse for wear! bit.ly/3YCVcUE 🔭 🧪

Coucou, il y a du monde ici?
Je crois que je vais être de plus en plus actif sur cette appli où le ciel est bleu. On va parler astronomie, sciences et apprendre en s'émerveillant!

Voici une étoile massive en fin de vie, WR 136, dont les vents sont extrêmes: 1900km/s, soit près de 7 millions de km/h! Cela a pour conséquence d’entraîner tout la matière autour et de former une bulle géante, qui fait ici 25 années-lumière de diamètre!
