Last calendar month , there was a big announcement : Venus appears to have amysterious source of phosphine , a speck that on Earth is associated with the disintegration of organic thing . However , several studies since then have bring the determination into query .
presently , we do n’t know whether or not there is phosphine in the cloud of Venus . The original employment included two independent observance of the sign for phosphine , but the datum for one of them may have been improperly calibrated and the analysis may have produced an unrealistically strong sign .
A new subject field inAstronomy & Astrophysics , which includes members of the original team , has abide by up on the original work . The team look for signal of phosphine on top of the clouds of Venus and found none . This by itself does n’t mean there is no phosphine at all in the Venusian atmosphere as it ’s possible it ’s located in the deeper layers and not float to the top .
However , the other more serious wrench in the works is a new psychoanalysis of the datum . The original sketch first used observations from the James Clerk Maxwell Telescope in Hawaii , which provided an challenging initial signal . A potential signature for phosphine was then notice , although the team could n’t be certain . For this rationality , they used the more sensitive Atacama Large Millimeter / submillimeter Array ( ALMA ) .
Their psychoanalysis once again showed the phosphine signature . The data is often full of noise , so the researchers used statistical analysis to corroborate or traverse the bearing of the sign – an endeavor that is far from simple or foolproof .
An self-governing teamre - analyzedthe same datum with the same method acting and found an inauspicious feature . The approach produce several other signals that look existent but in reality were not there . Their young analysis got free of those fakes but did n’t produce a strong signal for the phosphine . The possibility of phosphine is still there , but the information no longer allows scientist to say it is a definite detection .
On top of all of this , the ALMA data itself is now being re - processed as the observatory team hasfound an issuewith the data set used and it is now being recalibrated . It is presently indecipherable if it affected the original or follow - up subject area .
More observance are needed to confirm or deny the cosmos of this peculiar molecule on Venus , but we ought to be less unrestrained about it for now .
