Hubble Telescope Captures 25 Years of Crab Nebula Change

Summary

NASA has released a series of images from the Hubble Space Telescope showing the Crab Nebula as it appeared in 1999 and again in 2024. This 25-year comparison allows scientists to observe the nebula's expansion at 3.4 million miles per hour and changes in gas temperature and composition. The Hubble's longevity and resolution are crucial for such long-term astronomical studies, a capability NASA initially did not expect for the 35-year-old telescope. The comparison also implicitly shows advancements in camera technology, as the Hubble's cameras have been updated since its 1999 launch.

Key points

• Hubble Space Telescope images compare the Crab Nebula from 1999 and 2024.
• The images reveal the nebula's expansion and changes in gas composition over 25 years.
• Hubble's longevity and resolution are key to observing these long-term astronomical changes.
• The comparison also highlights advancements in telescope camera technology.
