Scattered within this cavernous nebula, NGC 604, are over 200 newly formed hot, massive, stars. At 1,500 light-years across, this expansive cloud of interstellar gas and dust is effectively a giant stellar nursery located in the spiral galaxy, M33, three million light-years distant.
The Orion Nebula from CFHT. Buried in the complex nebulosity are the bright stars of the Trapezium in Orion's heart, the sweeping lanes of dark dust that cross the center, the pervasive red glowing hydrogen gas, and the blue tinted dust that reflects the light of newborn stars
This is probably the most amazing photo you will see of the Orion nebula's center, a cloud of gas and dust known as M42. The work was created by Adam Block at the Mount Lemon Sky Center observatory in Arizona. Image: Adam Block/Mount Lemmon SkyCenter/University of Arizona
A spectacular Hubble Space Telescope image reveals the heart of the Lagoon Nebula. Seen as a massive cloud of glowing dust and gas, bombarded by the energetic radiation of new stars, this placid name hides a dramatic reality. The Advanced Camera for Surveys (ACS) on the NASA/ESA Hubble Space Telescope has captured a dramatic view of gas and dust sculpted by intense radiation from hot young stars deep in the heart of the Lagoon Nebula (Messier 8).
