Well, we also know where we haven't found signs of life. So from that perspective we have more data.

Probably not the best choice of words from me there. However, there is a positive correlation between a star's metallicity and the number of planets a star has.

Thanks for the clarification. You are absolutely right, in my post above I accidentally used the word "parallel" that caused the confusion. It wouldn't even be practically possible to use PLATO to observe them. Here's a

I should have been more clear in my original post. AFAIK there are two options on the table - looking at two fields, both 2 years OR looking at one field for 3 years and then doing "step and stare" for the rest of the mission. Ste

For many reasons. 1 - it might be very unique itself 2 - it might be very close to us 3 - it might be orbiting a very interesting star, a star type we didn't expect to have that planet type or so many planets, or so close, or so far,

Good question. No, these will essentially be black-white "photos". The amount of light is measured. The reason for so many CCDs is so that the field of view would be as large as possible. A larger field of view enables to look at

Great questions. > Is it to get a more exhaustive survey single star or can full of stars? PLATO will look at 100k+ stars at once. And for most we will be unlucky to see a transit between PLATO and the star. Geometrically it won't a

As far as I know it won't be affected at all, the project is almost fully funded from the European Space Agency. And it will most likely be launched with the European Ariane rocket.

Yes that's correct.

Yes, it's something that's referred to as pointing stability. The telescope will have star trackers to precisely know it's relative position - basically you make sure that you see the correct stars from where it is placed on

Figuring out the optimal placement of CCDs on Plato's 24(+2) cameras. Due to the way CCDs are fabricated, their properties vary a bit, they are not identical. For example, they can vary how much light they can hold before they become s

While it's possible for conditions for life to emerge or sustain itself to be present beyond the habitable zone (e.g. there's likely a subsurface ocean orbiting the farthest plant from the Sun on Triton), afawk it is more probable

It might be because we keep discovering more exoplanets. So far we have confirmed 5830 of them ( https://exoplanetarchive.ipac.caltech.edu/ ).

Next year there is a plan to send a space telescope to L2 with the main objective being to search for Earth-like planets around Sun-like stars in the habitable zone. Like Kepler and TESS telescopes it will use the transit method to find new

This is awesome. I went looking for FarFarOut ( https://en.wikipedia.org/wiki/2018_AG37 ), maybe would be cool to add it?

There are manufacturing processes that benefit from microgravity (e.g. growing protein crystals for the pharma industry, producing semiconductors, etc). Beyond that it would be a significant boon for science.

This sounds like scaling the service to more areas will slow :( . Surprising that Alphabet sees the savings to be worth a slower rollout.

Could you elaborate on "the way reviews are incentivized". As I understand it, guests review of the host is only visible to the host after the host has also reviewed the guest or a deadline has passed. Do hosts look at the reviews
