Tack till Hans Hilderfors<\/strong> som senast h\u00e4rom kv\u00e4llen, 7 februari, gav sig ut p\u00e5 kraterjakt p\u00e5 m\u00e5nen:<\/p>\n\n\n\n

Bildf\u00e4ltet p\u00e5 stora bilden \u00e4r 5,25\u00b4 x 3,94\u00b4 vilket motsvara 123 x 92 km. En pixel motsvarar cirka 0,21\u201d eller 392 m.<\/p>\n\n\n\n

Bilden tagen med min 6-tums refraktor och en svartvit CMOS-kamera med barlow.<\/p>\n\n\n\n

Det blev 2400 bilder varav de b\u00e4sta 1200 stackades till en bild.<\/p>\n\n\n\n

Uppl\u00f6sningen ligger ner mot teoretiska gr\u00e4nsen f\u00f6r mitt instrument.”<\/p>\n\n\n

L\u00e4ttviktare runt Proxima Centauri<\/h2>\n\n\n\n

Ett forskarlag som anv\u00e4nde Europeiska sydobservatoriets Very Large Telescope (ESO:s VLT) i Chile har funnit bevis f\u00f6r ytterligare en planet runt Proxima Centauri, den n\u00e4rmaste stj\u00e4rnan bortom solen. <\/p>\n\n\n\n

Denna kandidatplanet \u00e4r den tredje k\u00e4nda och den l\u00e4ttaste i systemet. Med bara en fj\u00e4rdedel av jordens massa \u00e4r den ocks\u00e5 en av de l\u00e4ttaste exoplaneter som hittills har hittats.<\/p>\n\n\n\n

Magnus Larsson<\/strong> kallar till ett nytt hypersp\u00e4nnande webinar 24 februari med novaexperten Christian Knigge<\/strong> (Southhampton U) som zoom-stj\u00e4rna.<\/p>\n\n\n\n

Knigge \u00e4r en auktoritet p\u00e5 \u00e4mnet och har bl a researchat p\u00e5 fenomenet jetstr\u00e5lar i dessa explosiva dubbelsystem (SS Cyg t ex), vilket anses vara ett s\u00e4rskilt sv\u00e5rf\u00e5ngat och sv\u00e5rber\u00e4knat fenomen.<\/p>\n\n\n\n
