A Swarm of New Asteroids, discovered by the Vera C. Rubin Observatory in about 10 hours of observations

rubinobservatory.org/gallery/c

0:00: Introductory animation 0:02: We start with a sprawling, textured field of galaxies scattered across the deep black of space. Rubin’s field of view is overlaid as a plus-shaped grid. A rectangle panel expands from the center right to show the grayscale sequence of the point of light of an asteroid moving left to right across the background. 0:12: Another panel expands from the right to show another asteroid moving left to right. 0:13: Yet another panel expands from the top with another asteroid moving diagonally to the upper right. 0:15: Six more panels with moving asteroids expand, to form a grid of nine. 0:20: Many more panels expand, forming a grid of 36. 0:28: The panels disappear, showing the original field of galaxies. Now, about 1000 teal dots appear on screen, representing Rubin’s discoveries on night 1 of observations. They’re generally moving toward the upper right at a leisurely pace. There are a few dots in purple and yellow, representing other types of Solar System objects. 0:32: More and more dots continue to appear as time progresses from night 1 to night 7, totaling 2104 objects. They’re mostly teal, representing main belt asteroids, but there are a couple dozen purple and yellow dots too. 0:42: The view rotates clockwise by about 45 degrees and zooms out to show the direction of observations and the objects detected from the perspective of Earth, seen in the foreground 0:45: The view continues to zoom out to show a bird’s eye view of the Solar System. Earth’s orbit is a circle inside the donut shape of the main asteroid belt filled with millions of dots. Rubin’s new detections are highlighted using the same colors as before, now seen as a narrow 3D cone shape extending from Earth out into the Solar System toward the top of the video.
rubinobservatory.orgA Swarm of New Asteroids (Video-EN)In about 10 hours of observations, NSF–DOE Vera C. Rubin Observatory discovered 2104 never-before-seen asteroids in our Solar System, including seven near-Earth asteroids (which pose no danger). Annually, about 20,000 asteroids are discovered in total by all other ground and space-based observatories. Rubin Observatory alone will discover millions of new asteroids within the first two years of the Legacy Survey of Space and Time. Rubin will also be the most effective observatory at spotting interstellar objects passing through the Solar System.

The 4 biggest mysteries the new Vera Rubin Observatory could solve

No telescope has basked in the night sky quite like this before. Here's what it could reveal about the universe.

Just two days to go before the public reveal of the first images!

A Glimpse of CLIMSO
* Image Credit & Copyright: Alain Sallez (picdumidi.org)

Explanation:
A tantalizing glimpse inside this dome was captured after sunset at the mountain top Pic Du Midi Observatory in the French Pyrenees. But while most are just beginning their work at sunset, this observatory's day was done. The instrument looming within is CLIMSO (for Christian Latouche IMageur Solaire), dedicated to exploring dynamic phenomena across the surface and atmosphere of the Sun. To image the solar atmosphere or corona, CLIMSO uses coronagraphs. Developed by French astronomer Bernard Lyot in the 1930s, coronagraphs block light from the center of the telescope beam to create an artificial solar eclipse and allow a continuous view of the solar corona. In this surreal twilight scene above a sea of clouds, the dome's interior was revealed by the single, long exposure as the open slit rotated across the field of view. eclipse.gsfc.nasa.gov/OH/OH201

The Vera C. Rubin Observatory will map the entire southern sky every few nights

The team will unveil the inaugural image on 23 June; in the meantime, the researchers are keeping quiet about what it shows. “We’ve been very serious about keeping it capped, so that we can do a big reveal”...

OST Observatory

Hi Mastodon! 👋
We are the OST (Overwhelmingly Small Telescope) Observatory at the University of Potsdam in Golm, on the outskirts of Potsdam, Germany.

Our main telescope is a PlaneWave CDK20 Astrograph. We focus on educating students in astronomy and supporting both undergraduate and postgraduate projects. We occasionally capture and share astronomical images, and we are excited to post some of them here.

We are also passionate about science outreach and regularly participate in public events such as the Potsdam Day of Science and the Long Night of Astronomy.

Follow us for updates in both English and German!
