Some 22% of online daters have asked someone to help them create or review their profile.
An intensive survey deep into the universe by NASA's Hubble and Spitzer space telescopes has yielded the image of the galaxy named SPT0615-JD, stretched and amplified by a phenomenon called gravitational lensing.
That is a substantial increase from the 43% of online daters who had actually progressed to the date stage when we first asked this question in 2005.
But it still means that one-third of online daters have not yet met up in real life with someone they initially found on an online dating site.
By combining the Hubble and Spitzer data, Salmon calculated the lookback time to the galaxy of 13.3 billion years.
Preliminary analysis suggests the diminutive galaxy weighs in at no more than 3 billion solar masses.
One-in-five online daters have asked someone else to help them with their profile.
Many online daters enlist their friends in an effort to put their best digital foot forward.First predicted by Albert Einstein a century ago, the warping of space by the gravity of a massive foreground object can brighten and distort the images of far more distant background objects.Astronomers use this "zoom lens" effect to go hunting for amplified images of distant galaxies that otherwise would not be visible with today's telescopes.Though a few other primitive galaxies have been seen at this early epoch, they have essentially all looked like red dots given their small size and tremendous distances.However, in this case, the gravitational field of a massive foreground galaxy cluster not only amplified the light from the background galaxy but also smeared the image of it into an arc.5% of Americans who are in a marriage or committed relationship say they met their significant other online.
