By Fernando J. Ballesteros

For a very long time i've been giving medical lectures in numerous nations and on different themes, regularly regarding astronomy and to my paintings on the Arecibo Observatory. regardless of which parti- lar subject i'm conversing approximately, a similar query consistently comes up: Have we had any touch at Arecibo with “them”? My unfavorable resolution doesn't fulfill someone. actually, the reply both confirms their suspicions that there's a conspiracy afoot via larger autho- ties to not liberate details or their intentions to mislead most people. the explanations for the deception need to do with the concept, as within the motion picture touch, the obtained messages include vital and important info that may deliver nice virtue to whoever will get it. many folks are looking to think that extraterrestrial creatures can seek advice from us, that maybe they're even dwelling between us, as alien craft lovers think. it might be attention-grabbing if it have been precise, a greater than additional- dinary discovery, the reply to an everlasting query. there's p- sibly a deep mental cause during this wish to be aware of if we're on my own during this large universe, and the necessity to think in whatever past our restricted international, in area and time. there's no doubt, then, that this subject brings with it many medical and philosophical discussions, in addition to speculations that, on many events, fall into natural pseudoscience as a result loss of a reference framework.

And this can have already got occurred. In April 2005, whilst an already photographed Martian torrent used to be back photographed, it displayed a wierd alteration. The torrent, which within the earlier photograph of 2001 seemed darkish, within the new photograph the water flowing! If we ensure that it really is certainly water and never sand torrents (as one other thought maintains), the presence of subterranean liquid water in Mars might carry with it amazing organic implications (Fig. three. 11). Fig. three. 11Martian gullies at the part of a crater. lower than correct, a torrent that has erased a part of a sequence of dunes. Above correct, a given torrent saw on diversified events indicates within the photograph of 2005 what seems liquid water flowing. Courtesy of MOC/MGS – NASA Martians! The extra we learn Mars, the extra surprises we discover. In 2004, the spectrometer of Mars exhibit present in the Martian surroundings methane gasoline! This discovery, proven from Earth by way of telescopes in Hawaii and Chile, posed a unconditionally unforeseen shock. Mars convey discovered that this methane isn't really uniformly disbursed in the course of the surroundings yet is focused in definite zones within the intermediate latitudes, zones the place torrents were came across. truly the maps of methane prevalence generated through Mars convey completely overlap with maps of water created by way of Mars Odyssey (Fig. three. 12). Fig. three. 12In 2004 ESA’s Mars show detected atmospheric methane which was once no longer uniformly allotted within the surroundings, yet targeted in a few components, overlapping with the components the place water vapor and underground water ice also are centred. This discovery has been later proven spectroscopically from Earth utilizing huge ground-based telescopes, as this photo got in 2009 through NASA scientist, that exhibits a picture of Mars superposed with a map of methane focus. Courtesy of NASA And back the query arises, the place does this methane come from? because it is such an risky gasoline because of ultraviolet radiation, whatever needs to be continually changing it within the surroundings. even if the presence of this fuel might be defined through volcanism (emanations of trapped underground methane), the very fact of now not having chanced on any minuscule sulfide hint linked to this methane led us to totally discard any volcanic beginning to it. at present it's terribly tough to justify the presence of this fuel within the Martian surroundings by way of a geological mechanism. Are we seeing the hint of extraterrestrial organic task? the fact is that this isn't the 1st time that we have got symptoms that a few type of existence can almost immediately exist on Mars. The Viking spacecraft that landed at the Martian floor in 1976 had payload experiments on board meant to bare the presence of organisms within the Martian soil in the event that they have been there. to this point, those are the one such experiments performed on Mars. Inexplicably, no Martian rover has the gear to do organic experiments on board, and the Beagle II probe, which carried on it a number of diversified experiments to look for Martian lifestyles, ended up crashing into Mars (Fig.
