It was the first interruption in the steady increase of U.S. ad expenditures since a tiny dip of 0.6percentt in 1970, and the largest drop in four decades.
The government's approval rating stood at 73% in mid-October only a tiny dip fromid-October onlyoyed when it took power in September.
And it orbits its parent star firmly inside the "habitable zone", in which temperatures are just right for liquid water.The planet was found by NASA's recently-defunct Kepler space telescope, which stared at hundreds of thousands of distant stars, looking for the tiny dip in brightness produced when a planet crosses in front of its star as seen from Earth.
That tiny dip in brightness gives us estimates for a number of parameters of the planet candidate.
As exciting as the plans for direct imaging are, most exoplanets are still found using indirect techniques – such as detecting a wobble in the position of the star that indicates it is being pulled slightly towards an orbiting planet, or a method called "transiting", in which planets are identified by the tiny dip in brightness caused when they pass in front of its star.
Kepler, an orbiting telescope owned by NASA, America's space agency, looks for exoplanets by identifying the tiny dip in brightness caused when one of them passes in front of its host star, as seen from Earth a phenomenon known as "transiting".
They measure tiny dips in a star's brightness that could indicate a planetary body passing in front of the camera's line of sight.
It stares at a fixed patch of sky, watching a field of more than 150,000 stars for the tiny dips in starlight that occur if an orbiting planet passes between a star and the telescope.
The spacecraft did so by staring at roughly 150,000 stars in a celestial patch representing 1/400th of the sky, waiting for tiny dips in starlight that would signal a planet was passing by, blocking a little bit of light.
