Image of the Day: Spectacular Beauty of an Aging Galaxy --"What Life Forms May Exist There?"

The NASA/ESA Hubble Space Telescope has captured a beautiful galaxy with its reddish and yellow central area, called NGC 5010. 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. Its alluring beauty makes one wonder what life forms may exist here.

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. Hubble's Advanced Camera for Surveys snapped this image in violet and infrared light.

Comments

At 140 MLY away, we should have contacted intelligent alien life within our own galaxy first. Whatever intelligent life in NGC 5010 that has achieved inter-gallactic travel probably went in the opposite direction of Earth in their search for intelligent life.
