vera C.Rubin Observatory Captures Stunning Image of Trifid Nebula, Revealing Stellar Nursery

A breathtaking image of the Trifid Nebula, a vibrant cosmic cloud in the Sagittarius constellation, has been unveiled by the Vera C. Rubin Observatory in Chile. The detailed portrait, officially known as Messier 20, offers unprecedented insights into the processes of star formation within our universe. The image was captured using the observatory’s LSST (Legacy Survey of Space and Time) camera, the world’s largest digital camera boasting a resolution of 3,200 megapixels.

Unveiling the Trifid Nebula’s Tri-Color Secrets

Located approximately 5,000 light-years from Earth, the Trifid Nebula derives its name from the Latin word meaning “divided into three parts,” a reference too its distinct structure bisected by dark lanes of cosmic dust. The newly released image showcases three different types of nebulae within a single frame:

• Emission Nebula: Displayed in pink,this is a gas cloud ionized by young stars,radiating its own light.
• Reflection Nebula: Exhibiting a blue hue, this type scatters light from nearby stars, similar to how streetlights illuminate fog.
• Dark Nebula: These dark paths consist of dense dust that absorbs light, creating the nebula’s characteristic tripartite appearance.

Pro tip: The different colors in nebulae reveal the physical processes occurring within them, offering clues about their composition and the stars they harbor.

NASA has previously noted that these colors are not merely aesthetic but reflect the diverse physical processes at play within the nebula.

Stellar Nursery: Where New Stars are Born

The Trifid Nebula is an active stellar nursery, a region where new stars are constantly being born. Within its clouds of gas and dust, stars are forming and emitting intense radiation, shaping the surrounding gas into spectacular formations. This image was created from 664 exposures taken over four nights in May 2025 and is available in a 40-megapixel enlarged version.

LSST Camera Details

The LSST camera, responsible for this stunning image, is mounted on the Simonyi survey telescope, wich features an 8.4-meter diameter main mirror.This powerful combination allows for incredibly detailed observations of the cosmos.

Vera C. Rubin Observatory’s Enterprising Mission

The Vera C. Rubin Observatory is embarking on a ten-year mission to photograph the southern sky every three to four days. This ambitious project will create the largest astronomical time-lapse in history, enabling scientists to monitor celestial changes in real-time. The team plans to photograph each section of the sky approximately 800 times, including continuous monitoring of the Trifid Nebula.

did You know? In its first week of observations, the Vera C. Rubin Observatory discovered over 2,100 new asteroids.
