Chandra Sees the Peacock’s Galaxy

Jul 22, 2024

To commemorate the 25^th anniversary of NASA’s Chandra X-ray Observatory launch, the Chandra team released this never-seen-before image of NGC 6872, a spiral galaxy in the Pavo (Peacock) constellation, on July 22, 2024. This image and 24 others, which all include data from Chandra, demonstrate how X-ray astronomy explores all corners of the universe.

NGC 6872 is 522,000 light-years across, making it more than five times the size of the Milky Way galaxy; in 2013, astronomers from the United States, Chile, and Brazil found it to be thelargest-known spiral galaxybased on archival data from NASA’s Galaxy Evolution Explorer. This record was surpassed by NGC 262, a galaxy that measures 1.3 million light-years in diameter.
