News Desk:
Earlier this month, scientists announced the discovery of a surprising phosphine on Venus. This compound of phosphorus and hydrogen may be related to life.

Although people are trying to confirm this discovery through observations of the Earth and even accidentally planned spacecraft flybys, the decades-old archived data of NASA’s missions to Venus may already be in people There are a lot of data hidden in his sight waiting to be verified, and there may be more revelations.

The discovery of phosphine in the atmosphere of Venus has been widely reported and aroused caution. In order to check the detection results again, scientists are eager to obtain more data, whether it is a large telescope or a new interplanetary mission.

If the presence of gas can be confirmed, researchers will be forced to deal with its origin, including the possibility that some form of single-celled life floats in planetary clouds.

Many experts believe that the best opportunity to verify Venus phosphine lies in atmospheric probes that can directly smell gas. But such a mission is not an imaginary future flight-in fact, the former Soviet Union’s Venera series spacecraft and NASA’s” Pioneer Venus” multi-probe probe are already in the atmosphere of our planet.

An instrument called the Large Probe Neutral Mass Spectrometer (LNMS) looks for gases in the atmosphere. Mission scientists focus on carbon dioxide, sulfur dioxide and Argon and other molecules known to be abundant there.

However, after reviewing the data again, Rakesh Mogul, professor of Biochemistry at California State Polytechnic University, Pomona, believes that the scientist performing the task underestimated Their instrument, the instrument may have found a small amount of other molecules, including exciting, phosphine.

Mogul said:” If these measurements are true, it means that phosphine has been on Venus for 40 years.” Perhaps the key evidence will actually come from the archives of past missions, which have been waiting for nearly half a century of recognition.
