It is the sort of out-of-this-world phenomenon that might have got E.T.himself jumping for ioy (if only his legs had been long enough).
Astronomers bare received three mysterious radio signals from outer space.
They picked them up while using a radio telascopc stationed in Puerto Rico to probe deep into the universe.
Each signal lasted about one minute and was recorded on the frequency which scientists believe aliens would be most likely to use, namely SHGb02+I4a (since you ask, this is the frequency at wbich hydrogen readily takes in and gives out energy.) According to New.Scientist magazine, the signal originates from a point her ween the Pi-es and Aries constellations (双鱼座和白羊座) where there is no obvious star or planetary system within 1,000 light years.
What is sending tbe signals is unknown, hut scientists working on the Search for Exlraterrestrial Intelligence project believe it could finally prove there is life “out there”.
”We are looking for something that screams out ‘artificial'“ said Eric Korpela, a researcher from the University of California, Berkeley.
”This just doesn't do that bot it could be because it is distant.”
Other scientists are not so sure it will point the way to alien life but they have ruled out a scientific joke.They believe it may be an unknown astronomical phenomenon or even a strange thing of the telescope itself.
”If they can see the signal four, five or six times it really begins to get exciting,” said Jocelyn Bell Burnell, from the University of Bath.

Although there are no state controlled survival courses in Britain or the United States,there are various independent organizations offering similar activities.
Students can take part in outdoor training courses through university clubs and societies.Anyone can register with such groups,which then organize courses,training and trips for all members.
One of the most popular outdoor training programmes in both the US and Britain,is Outward Bound(户外训练).It was founded in 1941 in Wales and attracts hundreds of thousands of adventurous types every year.
The courses are intended to broaden minds through experiences that build confidence,self-esteem(自尊)and character.As well as specialist courses such as canoeing, leadership skills and sailing,participants can take part in week long adventure training camps which include a host of sports and survival training education skills.
Michael Williams,an American student,took part in an Outward Bound course last year.He said:“We learned lots of first aid skills,lots of natural history,lots of environmental facts,and took part in a wildlife preservation programme.Beyond that,my favourite skills learned were sailing and rock climbing.”
Courses can last up to 40 days and are open to anyone over the age of 14.Students must be in general good health,but do not need to be experienced in outdoor-sports.There is no selection process;everyone is welcome,although new participants are advised to pick a course matching their physical capacity.
Most of the British courses take place in the Brecon Beacons in Wales.Another similar organization is the UK Survival School,which includes courses on learning to live with the environment,sailing and winter survival.On a basic survival weekend students will learn how to get water and food,how to make fire and cook with it,to find and build a shelter,control survival life support,how to cross rivers,send off a distress signal,and to use compasses by day and night.
According to the leaders,such adventures are “an awakening,an exploration into the unknown”.Outward Bound believes that participants will “use mind and body traveling some of the Earth’s roughest wilderness areas”.
