But the search for other intelligent life in space has been dealt a devastating blow which means we may never find out the answer.
The planet's only radio telescopes dedicated to searching for other life has been shut, the victim of U.S. government spending cuts.
The Allen Telescope Array in California has been mothballed after funding ran out, said senior astronomer Seth Shostak.

Residents who were left homeless after last week's tornado find shelter at the Belk Activity Center on Monday in Tuscaloosa, Ala.
The Federal Emergency Management Agency says some 30,000 people have registered for assistance, and more than 3,000 National Guard members are on the ground conducting search and rescue, security and debris removal.
Home these days for Starkey Armistead of Tuscaloosa, Ala., is one of dozens of cots lined up on the gym floor at the Belk Activity Center where he has stayed since a tornado destroyed his apartment.
"It's a little different sharing a bedroom with a hundred people, but you get used to it," he said.
Across the South, more than 800 people are staying in shelters like this one set up by the Red Cross. Others are staying with family and friends, or even in their damaged homes. Residents in Tuscaloosa on Tuesday scrambled to get broken windows boarded up and tarps over roofs before a cold rain set in.
Today, we are celebrating the death of former CIA employee Osama Bin Laden. Why are there no photographs of his body? Why was he buried in the sea? Why is he not on trial? Of course, we are not encouraged to question the official line.
Can one man be solely responsible for atrocities that kill thousands of people? As with Saddam Hussein, as with Muammer Gaddafi, the complete dehumanisation of Osama Bin Laden as an individual has served as the pretext for the killing of hundreds of thousands of people. If we were to follow the logic that the killing of one man called Bin Laden comprises 'justice' for the thousands of victims of 9/11, then what would 'justice' for the estimated one million Iraqis dead since the US and British-led invasion of Iraq entail?

An imam from the Al-Aqsa Mosque in Jerusalem vowed to take revenge over "the western dogs" for killing Al-Qaeda leader Osama bin Laden in Pakistan on Sunday.
In a Youtube video uploaded by the imam he said: "The western dogs are rejoicing after killing one of our Islamic lions. From Al-Aqsa Mosque, where the future caliphate will originate with the help of God, we say to them - the dogs will not rejoice too much for killing the lions. The dogs will remain dogs and the lion, even if he is dead, will remain a lion."
The imam then verbally attacked US President Barack Obama saying: "You personally instructed to kill Muslims. You should know that soon you'll hang together with Bush Junior."
"We are a nation of billions, a good nation. We'll teach you about politics and military ways very soon, with god's help," he vowed.
The announcement came as a response to an appeal by Bout's defense lodged on April 19. Among many other provisions, the 50-page document asks the court to end Bout's case as the U.S. government does not have jurisdiction to consider criminal cases over the offenses that have been committed outside the United States.
In their 60-page response to the appeal, prosecutors said they were ready to avoid labeling Bout as "the Merchant of Death" as a compromise, but demanded the court turn down all other requests by the defense.

In an email to The Daily Caller, Gina Channell-Allen, president of the Pleasanton Weekly in Pleasanton, California, said that her paper "received a call from the White House asking us to take out part of the story because it reflected poorly on the First Lady."
The story in question was a soft feature about Marine One titled, "Inside Marine One, President Obama's helicopter," that ran in the paper on April 20. Pleasanton staffer Amory Gutierrez "didn't get to ride in 'Marine One,'" she wrote in her story, "but I did get the VIP tour and took photographs of the otherwise unseen aircraft."
She also wrote a sentence that the White House thought made FLOTUS look snooty.
