The NASA/ESA Hubble Space Telescope has captured a beautiful galaxy
that, with its reddish and yellow central area, looks rather like an
explosion from a Hollywood movie. The galaxy, called NGC 5010, is in a
period of transition. The aging galaxy is moving on from life as a
spiral galaxy, like our Milky Way, to an older, less defined type called
an elliptical galaxy. In this in-between phase, astronomers refer to
NGC 5010 as a lenticular galaxy, which has features of both spirals and
ellipticals.
NGC 5010 is located around 140 million light-years away in the
constellation of Virgo (The Virgin). The galaxy is oriented sideways to
us, allowing Hubble to peer into it and show the dark, dusty, remnant
bands of spiral arms. NGC 5010 has notably started to develop a big
bulge in its disk as it takes on a more rounded shape.
Most of the stars in NGC 5010 are red and elderly. The galaxy no
longer contains all that many of the fast-lived blue stars common in
younger galaxies that still actively produce new populations of stars.
Much of the dusty and gaseous fuel needed to create fresh stars has
already been used up in NGC 5010. Over time, the galaxy will grow
progressively more "red and dead," as astronomers describe elliptical
galaxies.
