Den 14 juni, en m\u00e5nad efter uppskjutningen fr\u00e5n Kourou i Franska Guyana, tog ESA:s Herschel-teleskop av sitt skyddande \u2018objektivlock\u2019. Trots att det fortfarande var under testning beslutade uppdragsteamet att tidigarel\u00e4gga Herschels f\u00f6rsta observationer. Deras m\u00e5l var ett av de vackraste objekten p\u00e5 himlen \u2013 M51, \u00e4ven k\u00e4nd som Virvelgalaxen.<\/p>\n<\/div>\n<p>Herschels dj\u00e4rva \u2018f\u00f6rhandsvisning\u2019, som gjordes direkt efter att teleskopets skydd hade \u00f6ppnats, \u00f6vertr\u00e4ffade allas f\u00f6rv\u00e4ntningar. Testbilderna av den ber\u00f6mda spiralgalaxen togs i tre f\u00e4rger f\u00f6r att framh\u00e4va olika egenskaper. De visade sig vara de skarpaste bilderna av Whirlpool som n\u00e5gonsin tagits i infrar\u00f6tt ljus och visade tydligt den \u00f6verl\u00e4gsna prestandan hos Herschel, det st\u00f6rsta rymdteleskopet som n\u00e5gonsin skickats upp i rymden.
