Superbubble located in a star cluster in the N44 nebula, inside the Large Magellanic Cloud. The image is a composite, with the blue, high-energy portion taken by NASA’s Chandra X-ray Observatory. Additional data comes from the Spitzer space telescope, which observes cooler infrared wavelengths (outlined in red) and the European Southern Observatory’s Max-Planck-ESO telescope, which sees in ultraviolet (yellow).
Baby stars are forming near the eastern rim of the cosmic cloud Perseus in this infrared image from NASA's Spitzer Space Telescope. The baby stars are approximately three million years old and are shown as reddish-pink dots to the right of the image.
Molecular cloud Cepheus B, located in our Galaxy at about 2,400 light years from the Earth. A molecular cloud is a region containing cool interstellar gas and dust left over from the formation of the galaxy and mostly contains molecular hydrogen. - Credit: NASA/JPL-Caltech/ et al
M51, whose name comes from being the 51st entry in Charles Messier's catalog, is considered to be one of the classic examples of a spiral galaxy. At a distance of about 30 million light years from Earth, it is also one of the brightest spirals in the night sky. A composite image of M51, also known as the Whirlpool Galaxy, shows the majesty of its structure in a dramatic new way through several of NASA's orbiting observatories.
