The have found another Goldilocks world!

They found an earth'like planet, but its a little far for us to get there in one life time.

"earthlike" " 5,600 degrees Fahrenheit"

"earthlike" " 5,600 degrees Fahrenheit"

That's the temperature of the star the planet is orbiting. Which is significant because that's 56% the temperature of our own sun. The Stefan-Boltzmann law states that the heat irradiating from a blackbody is proportional to the temperature to the fourth power, so that means it gives off only 10% of the heat our own sun does. The star is also a lot smaller.

So even though this planet is a lot closer to than star, than the Earth is to the sun, it might not have a wild temperature. It just means that red dwarf stars have a goldilock zone much closer to them.

The bigger problem is the amount of ionizing radiation it would be experiencing. That could be problematic, and might just keep those planets sterilized.

Update:

Here's the source article https://www.sciencedaily.com/release...0220130456.htm

The calculated temperature of the planet at that distance is 319K +/- 28K

Thank you for the reference.

Even at a speed of 300 miles per minute, or 18,000 MPH, it would take over 3 million years to get there, so, other than scientific curiosity, I don't see the point.

The article quoted in the OP does say the surface of the planet is 5600 degrees. Is that a mistake?

Yes, That is a mistake. I always go directly to the sources, journalists usually get it wrong..

Ok, thanks for clarifying. I thought that was awfully hot for a planet orbiting a red dwarf.
And yeah, I think they need to have journalists with at least some scientific training be the ones to cover stories like this.

[demi-conservative]

Journalists rarely have any relevant training on any topic. Remember the Gell-Man effect:

Just a further caution, Science Daily is an aggregator of press releases, not a scientific source. While most universities try to make sure their press releases are accurate, there have been some rather dramatic exceptions. Plus they are under no obligations to present the caveats, limitations, etc. of the underlying research.

If you can find the paper, the abstract is almost always better than the press release.

Things don't need to have a practical application to be interesting. Where's your sense of scientific curiosity?

Usually at the end of the Science Daily article they'll have a link to the University Press release or the Abstract (and sometimes, the full paper).

Oh I find it interesting alright, but to suggest that 540 trillion miles away is tantalizingly close to the earth is a bit much. I'm of the belief that in the vast 4 billion light year expanse of this universes there is likely many such exoplanets capable of supporting life out there.

Typically, they're just republishing the press release verbatim. But yes, a link to the paper is helpful when available.
