Astronauts also replaced Hubble's solar panels with a more efficient array and conducted repairs on the NICMOS. The Hubble Space Telescope keeps getting photobombed, and it's just going to get worse. Following intensive training on the use of new tools never used before in space, two teams of astronauts completed repairs during a record five back-to-back spacewalks. And Hubble has helped scientists learn more about explosions that happen when huge stars burn out. Operating in space Not surprisingly, operating a telescope that is in outer space can be a hassle. During a total solar eclipse, the disk of the Moon blocks out that of the Sun, making the corona visible. smaller over each exposure than the 0 04 and 0 128 pixels for WFC-UVIS and WFC3-IR, respectively.
