Gammautbrott st\u00e4ller till det<\/h2>\n\n\n\n

H\u00e4ftiga gammautbrott i universum brukar delas upp i tv\u00e5 delar: korta utbrott som varar mindre \u00e4n 2 sekunder, l\u00e5nga utbrott som varar l\u00e4ngre \u00e4n tv\u00e5 sekunder.<\/p>\n\n\n\n

De f\u00f6rra tros bero p\u00e5 kompakta objekt typ neutronstj\u00e4rnor som g\u00e5r ihop, kolliderar med och kraschar in i varandra, de senare f\u00f6rklaras med d\u00f6dsryckningarna av snabbt roterande massiva stj\u00e4rnor.<\/p>\n\n\n\n

S\u00e5… d\u00e4rf\u00f6r misst\u00e4nks nu ett l\u00e5ngt utbrott bero p\u00e5 att tv\u00e5 himlakroppar (“kilonovae”) som g\u00e5tt ihop. Fenomenet \u00e4r \u00e4ven f\u00f6renat med gravitationsv\u00e5gor.<\/p>\n\n\n\n

Mars damm l\u00e4gger sig som damm<\/h2>\n\n\n\n

Vi vet ju att sandstormar drar fram \u00f6ver Mars med j\u00e4mna\/oj\u00e4mna mellanrum, men nu ser vi \u00e4ven hur solcellssystemen p\u00e5verkas i mikroformatet. Det vi ser nedan \u00e4r hur solcellspanelerna s\u00e5g ut t v 2018 d\u00e5 NASA:s InSight-landare kommit ner och tack vare solcellerna s\u00e4nde mess till oss – men sen i v\u00e5ras har dammet lagt sig \u00f6ver sonden och den har pl\u00f6tsligt bara en tiondels solkraft kvar. <\/p>\n\n\n\n
