Overview
NASA’s Chandra X-ray Observatory recently released stunning time-lapse videos of two celestial objects, Cassiopeia A and the Crab Nebula, condensing 20 years of observations into just 20 seconds.
The Crab Nebula
The Crab Nebula originated from a supernova witnessed by Chinese astronomers in 1054. At its core lies a neutron star, rotating rapidly and emitting radiation towards Earth like a cosmic lighthouse.
Key Points:
- Born from a supernova observed in 1054
- Contains a neutron star at its center
- Chandra observed it from 2000 to 2022
Cassiopeia A
Cassiopeia A is a younger supernova remnant, believed to have exploded around 340 years ago. Chandra’s observations from 2000 to 2019 have provided valuable insights into the formation of neutron stars and pulsars.
Key Points:
- Estimated to have exploded 340 years ago
- Chandra studied it from 2000 to 2019
- Discovery of a neutron star at its core
Chandra X-ray Observatory
Chandra has been instrumental in these observations, but concerns have been raised about its future due to budget cuts. While NASA mentions degradation in its systems, researchers argue that Chandra still has much to offer.
Current Situation:
Despite ongoing challenges, the study of these celestial wonders continues to captivate scientists and enthusiasts alike.
