Pondering questions such as What is in an exoplanet name Kudos to the METRO Back in January I reported on the shoddy journalism that produced two articles in the Daily Mail and the METRO newspapers . Both articles referred to a recent image from ESA's Herschel Space Observatory as being from NASA's Hubble Space Telescope . I was particularly frustrated by the one in the METRO because they generally do a pretty good job of covering space astronomy . news I'm pleased to say that , following my email to them , the METRO have corrected their online article They even added that some of the Herschel image was taken with ESA's .
