ALMA Observatory📡

Atacama Large Millimeter/submillimeter Array, is an international partnership of @ESO, @TheNRAO and @prcnaoj_en in cooperation with the Republic of Chile.

📡 We reveal planet-forming structures in small disks.

📷: 11 compact disks of planet formation in the Lupus region. The comparison illustrates planet formation at distances comparable to those of our own solar system.

🙌🏻Together with ESO, we joined @oh_stgo ! We welcomed visitors and led tours of the @ESO and ALMA facilities in Santiago, Chile. We talked about architecture and astronomy 📡🔭✨

Using @almaobs 's sharpest observations, astronomers have uncovered rings and gaps in compact disks, raising new questions about how planets form close to young stars.

📡"A swirling galaxy".
Like a portal to another dimension, a hypnotising swirl features in today’s Picture of the Week.
This is the spiral galaxy M83, also known as the Southern Pinwheel, located approximately 15 million light-years away.

Meet NGC 253, aka the Sculptor Galaxy! 🌌 At ~11.5 million light-years from Earth, it is one of the closest starburst galaxies to the Milky Way. Starburst galaxies transmute gas into new stars up to 1,000 times faster than typical spiral galaxies!

Rest in peace, Margaret. Your trailblazing work leading the development of the on-board flight software for the Apollo spacecraft will forever be remembered. 🫡
