They usually release false-color pics of one kind or another, based on spectroscopy, or exaggerate colors. In this case, the stars in the bulge, which are older, are reddened.

I would love to have that one as my background but I can't figure out how to do it. I have bg choices now courtesy of Google's Space Backgrounds. Can someone help?

Right click on the picture and click on save image as. Save it to photos on your computer. Open your photos and find the picture. Right click on the picture and click use as background. That should do it.

Newfound Asteroid Gives Earth a Close Shave By Mike Wall, Space.com Senior Writer | January 9, 2017 02:48pm ET
A smallish asteroid zoomed past Earth this morning (Jan. 9), just two days after scientists first spotted the space rock.
The asteroid, known as 2017 AG13, flew by our planet at just half the distance from Earth to the moon today at 7:47 a.m. EST (1247 GMT). (On average, the moon lies about 239,000 miles, or 385,000 kilometers, from Earth.) You can learn more about today's flyby in this video of asteroid 2017 AG13 from Slooh.com, which includes details on the space rock from Slooh Community Observatory astronomer Eric Edelman.
2017 AG13 is thought to be between 36 and 111 feet (11 to 34 meters) wide, according to astronomers at the Minor Planet Center in Cambridge, Massachusetts. For perspective, the object that exploded over the Russian city of Chelyabinsk in February 2013, injuring more than 1,000 people, was thought to be about 65 feet (20 m) wide. [In Images: Potentially Dangerous Asteroids]
2017 AG13 was discovered by the University of Arizona-based Catalina Sky Survey on Saturday (Jan. 7). Initial observations of the object show that it takes about 347 Earth days to circle the sun, on an orbit much more elliptical than that of Earth: 2017 AG13 gets as close to our star as 0.55 astronomical units (AU), and as far away as 1.36 AU.
One AU is the average distance from Earth to the sun — about 93 million miles, or 150 million km. Earth's orbit is nearly circular; the planet never gets closer to the sun than about 0.98 AU, or farther away than 1.02 AU or so.
Surprise flybys like the one just performed by 2017 AG13 are far from unprecedented. Millions of asteroids are thought to cruise through space in Earth's neighborhood, and astronomers have detected just 15,000 of them to date.
The good news is that the vast majority of the behemoths — the ones capable of causing damage on a global scale if they were to hit Earth — have been discovered, and none of them poses a threat for the foreseeable future, NASA researchers have said.

Looks to me very close to one of the backgrounds that comes with macOS, one of the ones I have in use now, along with the ISS, and three M&G pictures. :-) I think it's M-31 in Andromeda. You could google for M31 Andromeda wallpaper
and then select the Images tab in the results and pick and download your favorite. Or in a few days (can't really right now) I could send you what I've got; you might have to scale or crop it to best fit your desktop.
