Near the bottom, magnificent spiral galaxy M81, similar in size to our own Milky Way, shows off young stars in winding spiral arms.
Less than 100 million years old, the young stars are blue in the false-color GALEX image and seen to be well separated from the older yellowish stars of the galactic core.
But near the top, turbulent, irregular galaxy M82 shows the results of extreme rates of star birth and death.
Supernovae, the death explosions of massive stars, contribute to a violent wind of material expelled from M82's central regions.
The striking irregular and spiral galaxy pair are located only about 10 million light-years away in the northern constellation Ursa Major.
Wägä? Isch er z'dunkel oder hesch eifach die falsche Instrument zum en aluege?
Zwuesched jetzt und Mitte Januar gseht mer en am beschte, also ran an den Speck ;)
s'einzigä was i bisher gseh isch ä diffusi, venebliti schiäbä gsi. i han ca. 2 stund mit min feld-verstecher s'feld züschet alp ken, alp tau und orion abgsuecht, und i han nöd emol dä schweif chönne aluege, wäg ä wolke gmeint het: "hey döt park i emol" oder wäg sankt galler stadtplanig meint, mer müessti jede kiesselstei einzeln belüchtä.
alles i allem hoff i also uf ä kalti, klari, dunkli winternacht und uf en stromusfall.
