Rubin observatory unveils first images taken with its giant mirror and camera
Pictures are a prelude to a transformative, all-sky survey set to begin in months. More images and videos will be revealed in a livestreamed event today.
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!

www.nationalgeographic.com · The 4 biggest mysteries the new Vera Rubin Observatory could solve
Beautiful new cover of Science Magazine, starring the Vera C. Rubin Observatory
3 days to go before the first images are revealed!
We are 4 days from Rubin First Look, so we're locked in on our 4 science goals!
NSFF–DOE Rubin Observatory will focus on:
Understanding Dark Matter and Dark Energy 
Creating an Inventory of the Solar System
Mapping the Milky Way
Exploring the Changing Sky
As we begin to #CaptureTheCosmos, we hope to answer questions like what are dark matter and dark energy? How did our Solar System form and evolve? How did the Milky Way form, and how has it evolved?
Continued thread
We'll even have answers to questions we didn't think to ask!
Get ready to join us virtually for #RubinFirstLook — the grand reveal of images from Rubin, and the first preview of what's to come over the next ten years as Rubin begins to #CaptureTheCosmos

The Vera C. Rubin Observatory is set to transform astronomy. Its wide and fast survey will discover billions of dynamic objects while building up a deep map of the universe. #CaptureTheCosmos
First images will be revealed to the public on June 23 #RubinFirstLook

THIS IS NOT A DRILLWe are 6 days away from the world's First Look at images from Rubin!
NSF–DOE Rubin Observatory will take a new 3200-megapixel image every ~40s, yielding ~20 terabytes of data every night! The deluge of data is about to begin

T-7 days! We're getting so close to the reveal of NSF–DOE Rubin Observatory's first images 
#RubinFirstLook
Get ready for your first preview of how Rubin will #CaptureTheCosmos in its decade-long survey

The Universe is full of color 
NSF–DOE Rubin Observatory has 6 filters to see specific ranges of colors, labeled u, g, r, i, z, and y. They allow Rubin to #CaptureTheCosmos from high-energy ultraviolet (u), to visible light (g, r), to near-infrared (i, z, y).
Why do we need filters? 
Each filter helps scientists understand specific areas of interest, from young and hot stars that are bright in the ultraviolet, to very faint and distant old galaxies that are visible in the infrared.
We are T–10 days from NSF–DOE Rubin Observatory's First Look!
This reveal of Rubin's first images is just a preview of what's to come as Rubin prepares to #CaptureTheCosmos for the next ten years!
Here are 6 things you need to know before the big day
10 MILLION ALERTS INCOMING
NSF–DOE Rubin Observatory will repeatedly image the entire visible night sky, alerting scientists to changes in the brightness or positions of billions cosmic objects. There'll be up to 10 million alerts every night! We can't wait! 
Read more about the coming alert stream from Rubin Observatory at https://rubinobservatory.org/explore/how-rubin-works/alerts
We're only TWO WEEKS out from NSF–DOE Rubin Observatory's first images!
Get ready for the first preview of how Rubin will #CaptureTheCosmos in its decade-long survey in a live streamed #RubinFirstLook event on June 23, 2025 at 11am EDT!
