Astronomy Picture of the Day [1]Discover the cosmos! Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer. 2022 March 4 [2]See Explanation.

Loll et al.; T. Temim et al.; F. Seward et al.; VLA/NRAO/AUI/NSF; Chandra/CXC; Spitzer/JPL-Caltech; XMM-Newton/ESA; Hubble/[6]STScI Explanation: The Crab Nebula is cataloged as M1, the first object on [7]Charles Messier's famous list of things which are not comets. [8]In fact, the Crab is now known to be a [9]supernova remnant, expanding debris from massive star's death explosion, witnessed on planet Earth in 1054 AD. [10]This brave new image offers a 21st century view of the Crab Nebula by presenting image data from across the [11]electromagnetic spectrum as wavelengths of visible light. From space, [12]Chandra (X-ray) [13]XMM-Newton (ultraviolet), [14]Hubble (visible), and [15]Spitzer (infrared), data are in purple, blue, green, and yellow hues. From the ground, [16]Very Large Array radio wavelength data is shown in red. One of the most exotic objects known to modern astronomers, [17]the Crab Pulsar, a neutron star spinning 30 times a second, is the bright spot near picture center. Like a cosmic dynamo, this collapsed remnant of the stellar core powers the Crab's emission across the electromagnetic spectrum. Spanning about 12 light-years, the Crab Nebula is 6,500 light-years away in the constellation [18]Taurus.
