Instead of keeping it to themselves, your friend posts a notification: “Something changed here!” That’s the alert.🎉

But space is busy, so Rubin generates millions of alerts every night! 😲 That’s where Rubin’s “alert brokers” come in.🔭🧪

During its 10-year Legacy Survey of Space and Time (LSST), Rubin is expected to capture about 10 million supernovae 💥

The Universe is about to get a lot more exciting 😎

Our Solar System has millions of wandering asteroids and comets that are small, far away, and usually dark. Rubin Observatory excels at detecting faint objects, and it’ll find 10-100 times more Solar System objects than were known before! 🔭🧪
A wide-angle night panorama of Rubin Observatory on a rocky mountain peak, with a dirt road curving around from left to right. The full moon glows brightly near the horizon on the right, illuminating the landscape. Overhead, the Milky Way arcs across the sky, glowing with dense star fields, dark dust lanes, and red emission nebulae. The Large and Small Magellanic Clouds appear as bright fuzzy patches below the arcing band of the Milky Way.

And when it comes to the number of discoveries Rubin scientists will make about dark matter…the limit does not exist! ✨ 🔭🧪

That’s where NSF–DOE Rubin Observatory comes in. We’re not a regular observatory, we’re a cool observatory! 🔭🧪

The 10-year Legacy Survey of Space and Time (LSST) will measure observed distortions in billions of galaxies, revealing where the invisible dark matter is hiding.

Dark matter is the mysterious substance in the Universe that only interacts with regular matter (like you and us) via gravity. We can’t see it directly, but we see its influence as it bends light across the cosmos.🔭🧪

That way, scientists know the amount of signal that's due to the camera itself and can remove it from the raw images, leaving science-ready images that contain only the light from the cosmos✨🔭 🧪

Rubin Observatory's huge 8.4-meter telescope points at the in-dome calibration screen. On the right, and tilted left nearly to horizontal, the telescope is a huge, teal steel structure with a top and middle ring supported by thick beams connected to the telescope base. On the left, the calibration screen is a large white donut shape slightly wider than the top end of the telescope.
