Discussion Overview

The discussion revolves around an article regarding the distance and characteristics of a newly discovered exoplanet. Participants critique the article for its apparent errors, particularly concerning the distance measurement and the implications of such a distance in relation to the observable universe.

Discussion Character

  • Debate/contested
  • Technical explanation

Main Points Raised

  • Some participants find the article humorous due to perceived errors, suggesting that it contains numerous inaccuracies.
  • One participant questions the validity of the distance mentioned in the article, noting that 300 billion light years exceeds the observable universe's limits.
  • Another participant highlights a discrepancy in the distance, asserting that the correct figure should be 300 light years, not 300 million light years, and expresses curiosity about how such an error could occur.
  • Participants discuss the implications of the distance on the feasibility of imaging the planet and the age of its star, raising concerns about the consistency of the information presented.

Areas of Agreement / Disagreement

Participants generally express disagreement regarding the accuracy of the article's claims, particularly about the distance to the exoplanet. Multiple competing views remain regarding the interpretation of the article's content and the nature of the errors identified.

Contextual Notes

Limitations include the lack of clarity on the source of the distance measurements and the assumptions made in the article. The discussion does not resolve the discrepancies in the reported distances or the implications of those distances.

Apart from the distance, the weird size estimate and the mixture of "image exists <-> discovered via directing imaging", what is so wrong?
I did not check the timescale of direct observations.
 
Well, 300 billion light years...

That distance is 150 times further than the distance to the Andromeda galaxy, and since the observable universe has about a 45 billion light year radius, that distance is very well outside the observable universe.

At that distance, for them to have received the light now, the planet would have needed to emit light from a time older than the universe, but they estimate the planet's star is only 10-17 million years old.
 
Where does the number of 300 billion light years come from? The real value is 300 ly, and the first article has the wrong number of 300 million light years - way too far away for an image of a planet, but at least within the observable universe.
I wonder how such an error gets created.
