“N\u00e4rmare solen till dig…”<\/h2>\n\n\n\n

Det \u00e4r inte utan att vi t\u00e4nker p\u00e5 den klassiska psalmen n\u00e4r vi ser f\u00f6ljande bilder:
<\/p>\n\n\n\n

1954 \u00e5rs solf\u00f6rm\u00f6rkelse fick fotograflegenden Bertil Rubin<\/strong> att ta ett foto p\u00e5 taket till sitt f\u00f6retag mitt i Malm\u00f6. Flickan st\u00e5r p\u00e5 pallen f\u00f6r att komma n\u00e4rmare solen… Jaja, alla s\u00e4tt \u00e4r bra utom de direkt d\u00e5liga.<\/p>\n\n\n\n

Christian Vestergaard <\/strong>har fyndat i Yerkes-observatoriets (Chicago) arkiv och hittat damen som st\u00e5r p\u00e5 en pall f\u00f6r att observera stj\u00e4rnhimlen genom det stora teleskopet Det \u00e4r bara det att det finns ett r\u00f6rlig golv p\u00e5 Yerkes, s\u00e5 att st\u00e5 p\u00e5 en pall \u00e4r verkligen att “overdo” it. Tryck p\u00e5 en knapp och golvet kommer n\u00e4rmare. Stolen \u00e4r f\u00f6r att sitta p\u00e5, inte st\u00e5 p\u00e5.<\/p>\n\n\n\n

Asteroider ska utforskas fr\u00e5n m\u00e5nen<\/h2>\n\n\n\n

Jag h\u00e5ller precis p\u00e5 att l\u00e4sa Hans Rickmans<\/strong> fantastiska – och underh\u00e5llande! – popul\u00e4rskrivna faktabok Small Bodies of the Solar System<\/em> (en sorts “anm\u00e4lan” fr\u00e5n en glad amat\u00f6r kommer i en senare utg\u00e5va av W-bloggen), och p\u00e5passligt nog flaggas p\u00e5 junim\u00f6tet av American Astronomical Association f\u00f6r ett kommande kommersiellt m\u00e5nprojekt med optik som fr\u00e5n m\u00e5nen ska bevaka b\u00e5de bin\u00e4ra asteroider och Near Earth-objekt.<\/p>\n\n\n\n

M\u00e4rkligt raketnedslag p\u00e5 m\u00e5nen<\/h2>\n\n\n\n

Fr\u00e5n NASA ber\u00e4ttas att en m\u00e4rklig nyskapad dubbelkrater dokumenterats<\/a> av sonden Lunar Reconnaissance Orbiter. Nedslaget p\u00e5 m\u00e5nen, n\u00e4ra Hertzsprungkratern, skedde i fjor och resultatet blev tv\u00e5 kratrar, en i \u00f6stlig riktning p\u00e5 18 m diameter, som \u00f6verlappar en v\u00e4stlig krater med 16 m diameter.<\/p>\n\n\n\n

Dubbelkratern indikerar att nedslagsraketen haft tyngre material i b\u00e4gge \u00e4ndar. M\u00f6jligen \u00e4r det resterna av en av Apolloprojektets Saturnusraketer, en S-IVB som sp\u00f6kar. Men NASA vet inte.<\/p>\n\n\n\n
