La galaxie du Moulinet (ou Pinwheel galaxy ou encore M101) imag\u00e9e la nuit derni\u00e8re.
\nElle se laisse d\u00e9couvrir aux jumelles mais est tout de m\u00eame difficile visuellement au z\u00e9nith au printemps dans la constellation de la Grande Ourse.
\nC’est une galaxie spirale vue de face. Pourtant, sa forme spiral\u00e9e n’est pas r\u00e9guli\u00e8re.
\nEn effet, des galaxies satellites la \u00ab\u00a0tordent\u00a0\u00bb litt\u00e9ralement et provoquent dans les bras spiraux des ondes de choc qui cr\u00e9ent des nouvelles \u00e9toiles…
\nLes zones bleut\u00e9es dans les bras de la galaxie trahissent la pr\u00e9sence d’\u00e9toiles jeunes et tr\u00e8s chaudes tandis que le centre (plus jaune\/rouge) traduit la pr\u00e9sence d’\u00e9toiles plus \u00e2g\u00e9es et moins chaudes.
\nD\u00e9tails des prises de vues:
\n70 poses de 2 min avec un t\u00e9lescope de 280mm de diam\u00e8tre et de 1,7m de focale.<\/p>\n
