"A Look to the Heavens"

The Crab Nebula from Visible to X-Ray

"Explanation: What powers the Crab Nebula? A city-sized magnetized neutron star spinning around 30 times a second. Known as the Crab Pulsar, it is the bright spot in the center of the gaseous swirl at the nebula's core. About 10 light-years across, the spectacular picture of the Crab Nebula (M1) frames a swirling central disk and complex filaments of surrounding and expanding glowing gas. The picture combines visible light from the Hubble Space Telescope in red and blue with X-ray light from the Chandra X-ray Observatory shown in white, and diffuse X-ray emission detected by Imaging X-ray Polarimetry Explorer (IXPE) in diffuse purple. The central pulsar powers the Crab Nebula's emission and expansion by slightly slowing its spin rate, which drives out a wind of energetic electrons. The featured image released today, the 25th Anniversary of the launch of NASA's flagship-class X-ray Observatory: Chandra."

2002, "1054 A.D."
"This song and video by 2002 depict the great supernova of July 4, 1054 A.D., the remnants of which became the famous Crab Nebula. What must the civilizations of that time thought and felt when they saw this great star suddenly appear in the sky, visible even in broad daylight for 23 days?"
