Telescope discovered the indications of life on the distant planet K2-18B – BBC News in Serbian

Scientists found new, but unconfirmed evidence that on a remote planet that orbits around another star can exist for life.

The team from Cambridge studying the atmosphere of the planet by name K2-18B revealed signs of molecules that produce only simple organisms on Earth.

This is the second time that the powerful telescope of James Web (JST) has revealed the American Space Agency (NASA) in the atmosphere of this planet chemical elements related to life that can be promising.

More data is needed to confirm these results, the scientific team said, as well as independent astronomers.

Niku Madhusudan, a leading researcher, told me how to hope that final evidence would come soon.

« These are the strongest evidence so far about possible life out there.

« I can say that we will be able to confirm this signal within one to two years, » he added.

The planet K2-18B is two and a half times higher than the Earth and seven hundred trillion miles away from us.

The JVST telescope is so strong that it can analyze the chemical composition of the planet’s atmosphere from the lights that breaks with a small red sun around which orbits.

The atmosphere contains a chemical signature at least one of the two life-related molecules: dimethyl sulfid (DMS) and dimethyl disulfide (DMDS), discovered scientists from Cambridge.

These gases on Earth produce seafatoplankton and bacteria.

It’s surprisingly how much gas was discovered during the window of one observation, Madhusudan said.

« The amount of this gas we calculate in the atmosphere thousands is times more than what we have on earth.

« So, if the life of life is real, then this planet is flowing of life.

« If we confirm that there is life on the planet K2-18B, it would practically confirm that life is very common in the galaxy, » he says.

Much in this phase is still « if » and « But », as the Madhusudan’s team openly recognizes.

First, this latest discovery is not as requested to confirm the discovery.

For these researchers, they must be around 99,99999 per cent confident that their results are correct without random reading.

In the scientific jargon, it is the result of five Sigma.

These latest results are only three Sigma, 99.7 percent.

What sounds like much, but it’s not enough to convince the scientific community.

But it’s a lot More than scores One Sigma of 68 percent, who had only 18 months ago, and which came across many skepticisms of the scientific community at the time.

Even if the Cambridge team reaches five Sigma, it will not be definitive evidence that life exists on this planet, Ketrin Haymans from the University of Edinburgh and Royal Astronomy Scotland, which is independent of the research team.

« Even with that certainty, the issue of this gas origin is still.

« On the Earth, they produce microorganisms in the ocean, but we can certainly say a bunch of unusual things in the universe, which other geological activities could happen on this planet that could produce those molecules, » she says for the BBC News.

With this attitude, a team of Cambridge agrees, which cooperates with other groups to see if DMS and DMDS can be produced in non-life mode in the laboratory.

Other research groups presented alternative explanations without life for data obtained from the Q2-18B planet.

A violent scientific debate is guided not only whether DMS and DMDS are present, but also the composition of the planet itself.

The reason many researchers claim that the planet has a huge liquid ocean is the absence of ammonia gas in the atmosphere of the planet K2-18B.

Their theory is that ammonia absorbs a huge water mass below.

But they can equally be explained by the ocean of the dissolved rock, which would turn off life, according to Professor Oliver Shortl from the University of Cambridge.

« Everything we know about the planets that orbit around other stars comes from a small amount of light refused from their atmosphere.

« So it’s an incredibly faint signal we need to read, not just looking for life signs, but everything else.

« As for K2-18B, part of the scientific discussion is still conducted on the structure of the planet, » he says.

Nikolas Vagan from the research center of EJMS NASA has another interpretation of the data.

He has published a survey which suggests that the K2-18B mini gas giant is without a surface.

Both of these alternative interpretations have questioned the other group on the basis of not consistent with Data from the JVST, which only undertines a turbulent debate leading around K2-18B.

Madhusudan admits that he still remains the rise to the scientific mountain if he wants to answer one of the biggest questions in science.

But he believes he and his team on the right track.

« For decades, we will probably look at this period and understand that it was the moment when we live the universe was at hand.

« This could represent a turning point, when suddenly the fundamental question, we can actually answer the universe, » he concludes.
