How to pronounce“biosignature”in English

A biosignature is a sign of life.

The biosignature case certainly has had, I'd say, greater attention from entities like NASA and government funding agencies, because after all, you don't require

The biosignature case certainly has had, I'd say, greater attention from entities like NASA and government funding agencies.

for biosignatures, by which I mean oxygen, nitrous oxide, methane, it would take it of order of 200 transits

What sort of biosignatures or signs of life would we want to go look for?

So we talk about biosignatures, meaning anything that life leaves behind.

those so-called biosignatures.

The way biosignatures work is to look for gases that are emitted into the atmosphere which are uniquely produced by life.

The way biosignatures work is to look for gases that are emitted into the atmosphere which are uniquely produced by life.

The way biosignatures work is to look for gases that are emitted into the atmosphere, which are uniquely produced by life,

When we look for biosignatures, we're looking for templates of Earth-based life.

they may have more biosignatures than non-intelligent ones so they might be easier to detect that would be the hope

molecules that might be biosignatures to look at enceladus yes that's absolutely the plan is that what's that what's the limiting factor

signs of life by way of biosignature gases in a planet atmosphere far away.

One is with a so-called biosignature that is a signature of biochemistry essentially on another planet, and a second is a technosignature,

One is with a so-called biosignature, that is a signature of biochemistry essentially on another planet.

One is with a so-called biosignature.

And we look for things called biosignatures.

Astrobiologists look for what they call biosignatures, trying to discern some disequilibrium chemistry

Where should we be looking for biosignatures?

If you survey an exoplanet for biosignatures and you don't see oxygen, you don't see methane, that doesn't mean there's no one living there.

they can at least suggest whether there is any potential biosignature on exoplanets.

For example, biosignature gases are gases in an exoplanet atmosphere that could be attributed to life.

I do see our generation as finding what I'll call biosignature objects of interest, rather than like a confirmed legit sign of life

A growing concern has been these false positives in biosignature work.

Methane gas in combination with other gases can be an important biosignature.

You may have heard that there was a claim of a biosignature in Venus's atmosphere, I think it was like two years ago now.

We're always guilty that when we look for biosignatures, we are really looking for, and even when we look for planets, we're looking for templates of Earth.

at the beginning because assembly theory was built as a measure for biosignatures i needed to go there and then i realized it was intrinsic and

other planets within the solar system that might have phosphine or might have other strong biosignatures that we should be

It's actually already helping astronomers to analyze data from exoplanets, searching for a biosignature.

the atmosphere like you've described in your paper uh aptly titled the phosphine as a biosignature gas in exoplanet

that we would need to be able to answer these questions and to pick out that recipe of potential biosignatures.

And much of the effort in looking at Mars and other worlds in our solar system is to seek out those biosignatures.

And so in the near term, if we detect anything in terms of biosignatures, it's gonna be for one of these red dwarf stars.

But it could have also have been some of the molecule, in particular sulfur dioxide, which is not a biosignature.

In principle, technically, JWST could, technically, have the capability of just about detecting a biosignature on an Earth-like planet around

But it could detect, for example, a carbon dioxide rich atmosphere on TRAPPIST-1e, that's not a biosignature, but you could prove it's like a Venus in that case

There will be, for sure, a high profile journal like Nature or Science that will one day publish a paper saying biosignature discovered or something like

to earlier, you know, like detecting molecules in the atmospheres, not biosignatures.

And so we are never gonna, I would claim, really understand or complete this quest of looking for life biosignatures

And so you are left with this product, which is that, okay, we either believe or don't believe that biosignatures are there.

Do you hope, so one thing we've been talking about is getting signatures, biosignatures, technosignatures about other planets.

as an advanced civilization, or you could just be living underground or underwater or something where there's no biosignatures.

but you uh you write that there are about 16 000 molecules we care about when looking for a new earth or when we try to detect alien biosignatures

on earth that's not the case but it could be the case elsewhere oh it's not the case on earth most of the biosignatures we have on
