M81 and M82: GALEX Full Field


Explanation:

Intriguing galaxy pair M81 and M82 shine in this
full-field view
from the orbiting GALEX observatory.

GALEX - the Galaxy Evolution
Explorer
- scans the cosmos in
ultraviolet
light
, a view that follows star formation
and galaxy
evolution
through the Universe.

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.

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.
