Flyby of the Whirlpool Galaxy

Posted by

The Whirlpool Galaxy, also known as Messier 51, is one of the nearest and best examples of a grand design spiral galaxy. Located about 25 million light-years away, the face-on galaxy exposes the full details of its swirling structures of stars, gas, and dust. The striking symmetry of its spiral pattern may be due to a gravitational interaction with a companion dwarf galaxy, NGC 5195, which is not included in this visualization....

Shedding New Light on the Whirlpool Galaxy

Posted by

The Whirlpool Galaxy is a magnificent spiral galaxy that has been studied across the spectrum by NASA’s Great Observatories. This remarkable video uses two dimensional images and three dimensional visualizations to contrast and compare the different views of infrared (Spitzer Space Telescope), visible (Hubble Space Telescope), and X-ray (Chandra X-ray Observatory) observations. Within these spectral bands, each wavelength region illustrates a different component of the stars, gas, and dust that comprise the galaxy. By both separating and combining seven multiwavelength views, astronomers gain a broader and richer look into the detailed structure of a spiral galaxy.... Read More | Share it now!
