![]() These stellar infants, known as T Tauri stars, are less than 10 million years old, and their cores are still too cool for hydrogen fusion to start.Īstronomers study T Tauri stars to help understand the early stages of star formation and how planetary systems are created. The nebula is, however, home to many more stars, including a collection of about 45 young, low mass stars. Two bright stars, HD 38563A and HD 38563B, are the main powerhouses behind Messier 78. In astronomy, reflection nebula are clouds of interstellar dust which might reflect the light of a nearby star or stars. Youll find Messier 42 in the Sword of the Orion constellation. In the bottom right corner, several pink structures can be seen, which are created by jets of material being ejected from stars that have recently formed and are still buried deep within clouds of dust. With an apparent magnitude of +4, this glowing emission nebula/reflection nebula can. The image of Messier 78 contains several other striking features, including a thick band of dust that stretches across the image from the upper left to the lower right, which obscures the light from the background stars. The contest invited amateur astronomers to dig through ESO's vast archives and transform raw, gray-scale telescope observations into gorgeous full-color images of space. ![]() The data used to construct the image were chosen by Igor Chekalin from Russia, who was the overall winner of ESO's Hidden Treasures 2010 astrophotography competition. This new image of the Messier 78 reflection nebula was taken with the Wide Field Imager on the MPG/ESO 2.2-meter telescope at the La Silla Observatory in Chile. The shorter wavelength of blue light is scattered more efficiently than the longer wavelength of red light. Blue hues are commonly seen in reflection nebulas because of the way the starlight is scattered by the tiny dust particles. The pale blue tint seen in the reflection nebula is an accurate representation of its dominant color. It can be found northeast of the easternmost star of Orion's belt. Messier 78 is primarily a reflection nebula, which means it is composed of interstellar dust that reflects the light of nearby stars. a vast region of interstellar gas and dust where new stars are being formed. This star-forming region is located about 1,350 light-years away in the constellation of Orion (The Hunter). Messier 78, or M78, is a reflection nebula in the constellation Orion. Messier 78, or M78, is one of the brightest reflection nebulas in the sky and can be easily observed with a small telescope.
