'Crown of Thorns' Galaxy Photographed in Space



 An unusual large galaxy with a shape bordering between spiral and elliptical has been spotted by NASA's Hubble Space Telescope.

NGC 7049 sits in the southern constellation Indus, and is the brightest of a cluster of galaxies, a so-called Brightest Cluster Galaxy (BCG). Typical BCGs are some of the oldest and most massive galaxies, which provide excellent opportunities for astronomers to study the elusive globular clusters lurking within.

The halo, a ghostly region of diffuse light surrounding the galaxy, is composed of myriads of individual stars and provides a luminous background to the swirling ring of dust lanes surrounding NGC 7049's core.

Small faint points of light sprinkled throughout the galaxy represent globular clusters, which are gravitational groupings of several hundreds of thousands of stars. They contain some of the first stars to be produced in a galaxy.

NGC 7049 has far fewer such clusters than other similar giant galaxies in very big, rich groups. This indicates to astronomers how the surrounding environment influenced the formation of galaxy halos in the early universe.

The article doesn't mention how many thousands of years ago the reflected light left the imaged surface for it to reach the Hubble in this era.  It may look completely different or not exist at all anymore in real time.

It's doubtful that any of those deep space objects would look the same close up.  Then again, there was no one around the thousands of years ago to witness them.  Just maybe someone planned for them to be seen at this place and time.

That's my thinking, but yet my mind wanders.

No, my friends, there’s only one really progressive idea. And that is the idea of legally limiting the power of the government. That one genuinely liberal, genuinely progressive idea — the Why in 1776, the How in 1787 — is what needs to be conserved. We need to conserve that fundamentally liberal idea. That is why we are conservatives. --Bill Whittle

Cool images as always. The light we are seeing is from thousands of years ago.
