M 86 - NGC 4406
Penryn, California
April 2009
M 250 @ f9.3 (ag, ST-4)
ST-10XME LRGB 10 minute subs

M 86 is a giant elliptical galaxy in the Virgo group being stripped of gases due to ram pressure as it falls towards the center of the Virgo group (Randall, et. al. 2008).  Distance to M 86 is 4 Mly.

M 86 experienced a recent close encounter with NGC 4438 of the Virgo group.  NOAO recently released a study of this encounter noting  "A deep new image of the Virgo cluster has revealed monumental tendrils of ionized hydrogen gas 400,000 light-years long connecting the elliptical galaxy M86 and the disturbed spiral galaxy NGC 4438."
