On the background, this collage shows a fresco painted in 1509-1511 by Raphael in the Vatican (Stanza della Segnatura, Palazzi Pontifici), perhaps depicting the embodiment of Astronomy (copyright Photo Scala, Florence). Replacing the original astronomical globe is an image of Mars built by Freie Universität of Berlin with data from the Mars Global Surveyor's MOLA and MOC instruments (FU Berlin/MSSS and MOLA teams). The Mars globe merges into an image of X-ray sources in the Lockman Hole taken by ESA's XMM-Newton spacecraft (G.Hasinger, Astrophysikalisches Institute, Potsdam).
