DESERT,CALI.—Are wealone in the universe?Do other crea-tures,other intelligent beings exist in thestarry reaches of deep space?  \nScience fiction tales—from OrsonWelles'\"War of the Worlds\"broadcast(page 2)to the current holiday movie hitsDune and 2010—show a universe full ofextraterrestrial life.And many of to-day's scientists,it seems,agree with thescience fiction writers.  \nA committee of well-known scientistsat the National Academy of Science re-cently reported that there is strong rea-son to suppose that life does existelsewhere in the universe.The commit-tee suggested that it is likely that otherplanetary systems exist around other stars.And,if such planetary systems do exist,it is at least possible that some of theplanets in these systems have developedcivilizations more advanced than ourown.  \nEstimates of how many of these ad-vanced civilizations could exist varyamong scientists from fewer than 10 tomore than 200million.  \nWith all those supposed E.T.'s outthere,why haven't they contacted Earth?Many scientists believe that alien spacecivilizations could actually be sending outradio messages from deep in space.But—until now—we haven't been able tohear them.  \nSETI  \nIn early January,NASA(the NationalAeronautics and Space Administration)will take a giant step toward opening upour ears to messages from space.NASAwill begin operation of a second largeradio telescope devoted exclusively toSETI(the Search for ExtraterrestrialIntelligence).The radio telescope,whichis really a large supersensitive antenna  \ndesigned to pick up radio waves fromspace,is located in California's remoteMojave Desert.It joins another large SETIradio telescope already operating acrossthe country in Massachusetts.  \nThe two radio telescopes are pro-grammed to continuously scan the skyand pick up radio signals from space.Eachtelescope is connected to a powerfulcomputer that can sort out the signals atthe incredible rate of 10 million signalsper second.  \nThe computers are able to separatenatural radio signals from stars and otherobjects in space from signals that may becoming from alien civilizations.SETIscientists are most interested in a steadymicrowave beacon.Certain kinds ofmicrowaves(the same kind of radio wavesthat do the cooking in microwave ovens)are not natural to space.As far as scien-  \nContinued on Next Page  \nContinuedfrom Page1  \ntists know,these waves can be producedonly by humans or other intelligentbeings.  \nA Long,Long Shot  \nScientists hope that NASA's new pro-gram will greatly increase the chances ofpicking up an alien radio beacon.But,asone scientist said,the new equipment upsthe chances from“very,very slim”toonly\"very slim.\"The problem is the sizeof the known universe—something sohuge that it boggles even the scientificmind.  \nMost astronomers estimate that theknown universe contains about 100 sex-tillion stars.(To write 100 sextillion infigures,write I with 23 zeros after it!)That's equal to the number of grains ofrice spread over an area the size of thestate of Maine to adepth of%4 mile.Even  \nMomber o  \n# The Martians Are Coming'\n\nWhat would it be like if human beingsactually met intelligent creatures fromouter space?On Oct.30,1938,more thana million Americans thought they knew.  \nThat night,CBS offered a radio showabout an attack on Earth by MartiansThe show was based on the novel TheWar of the Worlds by H.G.Wells.Thedirector,Orson Welles,and his staffpre-sented the story through a series of newsbulletins.Throughout the broadcast,lis-teners received several warnings that thebulletins were fictitious.  \nActors playing newscasters talked ex-citedly about the landing of a large metalobject in New Jersey.One described thehorrifying creatures that reared out of theobject as having \"black eyes,a V-shapedmouth that dripped with saliva,and rim-  \nif there were as many as 200 million ad-vanced civilizations among these stars,aradio telescope
