Explanation:
This popular group leaps into the early evening sky around the
March equinox and
the
northern hemisphere spring.
Famous as the
Leo Triplet,
the three magnificent galaxies found in the prominent
constellation
Leo
gather here in one astronomical field of view.
Crowd pleasers when imaged with even modest
telescopes, they can be introduced individually as
NGC 3628 (bottom left), M66 (middle right), and M65 (top center).
All three are large
spiral galaxies
but 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 over 1 degree (two full moons) on the sky.
Captured with a telescope from
Sawda Natheel, Qatar, planet Earth,
the frame covers over half a million light-years at the
Leo Trio's estimated 30 million light-year distance.
