Ja, veldig gøy dette!

"This is the strongest evidence yet there is possibly life out there. I can realistically say that we can confirm this signal within one to two years."

at this stage, as Prof Madhusudhan's team freely admits.

Firstly, this latest detection is not at the standard required to claim a discovery.

For that, the researchers need to be about 99.99999% sure that their results are correct and not a fluke reading. In scientific jargon that is a five sigma result.

These latest results are only three sigma, 99.7%. Which sounds a lot, but it is not enough to convince the scientific community. But it is much more than the one sigma result of 68% the team obtained 18 months ago,, which was greeted with much scepticism at the time.

But even if the Cambridge team obtains a five sigma result, that won't be conclusive proof that life exists on the planet, according to Prof Catherine Heymans of Edinburgh University and Scotland's Astronomer Royal, who is independent of the research team.

"Even with that certainty, there is still the question of what is the origin of this gas," she told BBC News.

"On Earth it is produced by microorganisms in the ocean, but even with perfect data we can't say for sure that this is of a biological origin on an alien world because loads of strange things happen in in the Universe and we don't know what other geological activity could be happening on this planet that might produce the molecules."

That view is one the Cambridge team agree with; they are working with other groups to see if DMS and DMDS can be produced by non-living means in the lab.

Når russarane seier det Indiske hav er det vel 100% sikkert at Kosmos 482 ikkje landet i nærheten i det heile tatt.

Sitat

 

En del av den sovjetiske raketten Kosmos 482 har krasjet på jorda etter over 50 år i verdensrommet.

Det melder det svenske nyhetsbyrået TT. Det er også bekreftet av Den europeiske romfartsorganisasjonen.

Lørdag ettermiddag opplyser den russiske romfartsmyndigheten Roskosmos at romfartøyet har landet i Indiahavet. Det er foreløpig ikke kjent hvor, eller om det er funnet vrakrester.

Kraftig aktivitet på sola: – Det kan se ut som vi er nær toppen eller kanskje akkurat over
Sola hadde nylig sine kraftigste utbrudd i 2025.
