Crab Nebula in technicolor! This new composite view combines data from five different telescopes, showing the celestial object in multiple kinds of light.
The video starts with a composite image of the Crab Nebula, a supernova remnant that was assembled by combining data from five telescopes spanning nearly the entire breadth of the electromagnetic spectrum: the Very Large Array, the Spitzer Space Telescope, the Hubble Space Telescope, the XMM-Newton Observatory, and the Chandra X-ray Observatory.
It then dissolves to the red-colored radio-light view that shows how a neutron star’s fierce “wind” of charged particles from the central neutron star energized the nebula, causing it to emit the radio waves.
The yellow-colored infrared image includes the glow of dust particles absorbing ultraviolet and visible light.
The green-colored Hubble visible-light image offers a very sharp view of hot filamentary structures that permeate this nebula.
The blue-colored ultraviolet image and the purple-colored X-ray image shows the effect of an energetic cloud of electrons driven by a rapidly rotating neutron star at the center of the nebula.
The Witch Head Nebula : Double, double toil and trouble; Fire burn, and cauldron bubble . maybe Macbeth should have consulted the Witch Head Nebula. A frighteningly shaped reflection nebula, this cosmic crone is about 800 light-years away though. Its malevolent visage seems to glare toward nearby bright star Rigel in Orion, just off the right edge of this frame. More formally known as IC 2118, the interstellar cloud of dust and gas is nearly 70 light-years across, its dust grains reflecting Rigels starlight. In this composite portrait, the nebulas color is caused not only by the stars intense bluish light but because the dust grains scatter blue light more efficiently than red. The same physical process causes Earths daytime sky to appear blue, although the scatterers in planet Earths atmosphere are molecules of nitrogen and oxygen. via NASA
