Explanation:
This group is popular in the northern spring.
Famous as the
Leo Triplet,
the three magnificent galaxies gather in one field of view.
Crowd pleasers when imaged with even modest
telescopes, they can be introduced individually as
NGC 3628 (left), M66 (bottom right), and M65 (top).
All three are large
spiral galaxies but
they tend to look dissimilar because their galactic disks are
tilted at different angles to our line of sight.
NGC 3628,
also known as the Hamburger Galaxy,
is temptingly seen edge-on, with obscuring dust lanes
cutting across its puffy galactic plane.
The disks
of M66 and
M65 are
both inclined enough to show off their spiral structure.
Gravitational interactions between galaxies in the group
have left telltale signs, including the tidal tails and
warped,
inflated disk of NGC 3628 and the drawn out spiral arms of M66.
This gorgeous view
of the region spans almost two degrees (four full moons) on the sky.
The field covers about a million light-years at the
trio's estimated distance of 30 million light-years.
Of course
the spiky foreground stars lie within our own Milky Way.
