As a result, it is quite possible that a diet of organic foods will have only a modest effect on total exposure to pesticides. (treehugger.com)
But by staring at the region close to the black hole for more than 20 hours of total exposure time with the SINFONI instrument on the VLT — the deepest exposure of this region ever with an integral field spectrometer [3]-- the team was able to measure the velocities of different parts of the cloud as it streaks past the central black hole [4].

In May Hubble will collect more data on this first field, bringing the photo's total exposure time to 103 hours, and over the next three years it will examine the other five Frontier Fields, which were chosen at spots where nature's most powerful gravitational lenses lie. (scientificamerican.com)
