In summary, the Washington Post covered the IXPE orbiting telescope and discussed Cassiopeia A, a remnant of a supernova explosion that occurred 11,000 light-years away. The article also mentioned mixing the time of observation with the actual time of event and received a low rating on a scale of 1 to 10. Additionally, the concept of an ether was brought up in relation to Albert Einstein's missed calls.

From the Washington Post's coverage of the IXPE orbiting telescope:
Cassiopeia A is the remnant of a supernova explosion that took place when a gigantic star collapsed in the 17th century. It's visible in the night sky about 11,000 light-years away

Mixing the time of observation with the actual time of event?

Come on, starting a rant for every illogical absurdity picked from the news would earn me a permanent ban within a day, I guess :doh: Don't take this so seriously o0)

On a scale of 1 ... 10, that WP article gets a "minus 3" - since we clearly can use any number we want to rate it.

Either there is an ether or there's not. It's ether-or.

FAQ: Exploring Cassiopeia A: The 17th Century Supernova Remnant

What is Cassiopeia A?

Cassiopeia A is a supernova remnant located in the Cassiopeia constellation. It is the remnant of a massive star that exploded in a supernova event around 350 years ago.

How was Cassiopeia A discovered?

Cassiopeia A was first observed in the 17th century by British astronomer John Flamsteed. However, it was not recognized as a supernova remnant until the 1950s when radio astronomers detected its radio emissions.

What makes Cassiopeia A unique?

Cassiopeia A is unique because it is one of the youngest and brightest supernova remnants in our galaxy. It also has a complex structure and emits a variety of wavelengths, making it a valuable object of study for astronomers.

How do scientists study Cassiopeia A?

Scientists study Cassiopeia A using a variety of telescopes and instruments, including radio telescopes, X-ray telescopes, and optical telescopes. They gather data from different wavelengths to create a complete picture of the supernova remnant and its evolution over time.

What can we learn from studying Cassiopeia A?

Studying Cassiopeia A can provide us with valuable insights into the life and death of massive stars, as well as the processes involved in supernova explosions. It can also help us understand the formation of new stars and the role supernovae play in enriching the universe with heavy elements.
