Discussion Overview

The discussion revolves around the potential existence of a new "Goldilocks" planet, specifically Gliese 581 g, and the possibility of water on it. Participants explore the latest findings regarding its habitability and the reliability of data supporting its existence.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • Some participants inquire about recent updates on the Goldilocks planet and its potential for water.
  • One participant notes that a different group analyzing wobble data could not confirm the existence of the planet, suggesting the 36-day wobble might be noise.
  • Another participant recalls reading about Gliese 581 and suggests looking up recent news, mentioning a Wikipedia article that discusses the lack of confirmation and the latest theories regarding the planet's temperature and atmosphere.
  • It is mentioned that Gliese 581 has four confirmed planets and two unconfirmed ones, including Gliese 581 g.
  • One participant expresses skepticism about the planet being a good candidate for life, questioning the implications of it being tidally locked and suggesting that this would hinder the development of a substantial atmosphere.
  • A resource link is provided for further information on exoplanets.

Areas of Agreement / Disagreement

Participants express differing views on the existence and habitability of Gliese 581 g, with some questioning the validity of the data and others discussing the implications of its characteristics. No consensus is reached regarding its potential for supporting life.

Contextual Notes

There are unresolved questions about the reliability of the wobble data and the assumptions regarding the planet's atmosphere and conditions for life.

Last I heard, another group (analyzing an even larger body of wobble data) was unable to confirm.
So it is not clear that there is such a planet. The 36-day wobble they thought they saw could have been spurious (noise).

====================

I am just responding based on what I remember reading sometime in the past month or so. I think you are talking about a planet around Gliese 581. We could google "Gliese 581 g" an see if there is any recent news.

I googled and found this Wippy article:
http://en.wikipedia.org/wiki/Gliese_581_g

It has been kept up to date. It tells how the other group failed to confirm the existence of Gliese 581 g.

It also explains the latest thinking about temperature and atmosphere---how, if the planet exists, and has the estimated mass and distance from its star, it might be able to support living organisms.

======================

Gliese 581 has 4 confirmed planets: b, c, d, e.

And 2 (so far) unconfirmed planets: f, g.

ok thanks!
 


I think that so called goldilocks planet is not very promising.

How can they say, for instance, that it is tidally locked and yet a good candidate for life? Nonsense. Any tidally locked planet is a hopeless cause for complex life - the atmosphere would be almost nonexistent.
 


http://exoplanet.eu/" is an excellent resource for all aspects of this topic.
