Den statsejede virksomhed Roscosmos og P.N. Lebedev Physical Institute ved den Russiske Videnskabsakademi (FIAN) pr\u00e6senterede projektet \u00abMusik fra pulsarer\u00bb.<\/p>\n

\"\u00abMusikken<\/p>\n

Pulsarer er hurtigt roterende neutronstjerner med ekstrem h\u00f8j t\u00e6thed. De har en rotationsperiode og en bestemt modulation af den str\u00e5ling, der n\u00e5r Jorden.<\/p>\n

Signals fra pulsarer kan anvendes som tidsreferencer og pejlem\u00e6rker for satellitter, og ved at konvertere deres frekvens til lydb\u00f8lger kan man skabe en slags musik. Det er netop s\u00e5dan en \u00abmelodi\u00bb, russiske eksperter har skabt.<\/p>\n

Til at danne \u00abmusikken\u00bb blev der anvendt data fra det orbitale teleskop \u00abSpektr-R\u00bb. Dette apparat danner sammen med jordbundne radioteleskoper et radi interferometer med en superbred base \u2013 grundlaget for det internationale projekt \u00abRadioastron\u00bb. Teleskopet blev opsendt tilbage i 2011. I begyndelsen af dette \u00e5r opstod der et problem med apparatet \u00abSpektr-R\u00bb: observatoriet holdt op med at reagere p\u00e5 kommandoer. S\u00e5ledes er missionen for observatoriet angiveligt <\/a>afsluttet<\/a><\/noindex>.<\/p>\n

Det skal bem\u00e6rkes, at teleskopet \u00abSpektr-R\u00bb har indsamlet en enorm m\u00e6ngde vigtig videnskabelig information i l\u00f8bet af sin drift. Det var netop disse data, der gjorde det muligt at realisere projektet \u00abMusik fra pulsarer\u00bb. \u00abNu kan alle h\u00f8re, hvordan det kosmiske 'orkester' af 26 pulsarer lyder, som russiske forskere har studeret baseret p\u00e5 data fra det orbitale teleskop 'Spektr-R' og projektet 'Radioastron'\u00bb, bem\u00e6rker Roscosmos. <\/p>\n
