"Gaze up at the Sagittarius constellation, and you are looking at the
center of the *Milky Way*
<https://www.livescience.com/63847-facts-about-the-milky-way.html> galaxy.
It may not look like much to the naked eye (especially if a bunch of *space
junk* <https://www.livescience.com/space-junk-blocks-view-of-cosmos.html>
is blocking your view), but to the world's sharpest *X-ray*
<https://www.livescience.com/32344-what-are-x-rays.html> and *radio*
<https://www.livescience.com/50399-radio-waves.html> telescopes, the archer
hides a chaotic collage of *black holes*
<https://www.livescience.com/black-holes.html>, exploding stars, magnetic
fields and inexplicable bubbles of gas.

Now, using data from two such telescopes — NASA's Chandra X-ray Observatory
and the MeerKAT radio telescope in South Africa — researchers just pieced
together the most comprehensive picture yet of our galaxy's center. The
result is a glorious tangle of orange, green and purple X-ray emissions,
intertwined with tendrils of ghostly gray radio signals.

This image is an "unprecedented" view of the galactic center, plus the
mysterious structures towering above and below it, *according to a
statement* <https://chandra.harvard.edu/photo/2021/gcenter/index.html> from
Chandra researchers.

"The new panorama of the galactic center builds on previous surveys from
Chandra and other telescopes," the researchers wrote in the statement.
"This latest version expands Chandra's high-energy view farther above and
below the plane of the galaxy — that is, the disk where most of the
galaxy's stars reside" — than any previous imaging campaign, combining 370
separate observations from Chandra, the team added."
