AT THE CENTER OF OUR GALAXY

A Supermassive Black Hole with a Swirling Swarm of Hundreds of Smaller Holes?

Thousands of black holes near Milky Way center?

DISCOVERY
"...the discovery of...12 stellar-mass black holes, identified via X-ray data near our galaxy’s center."

"The Milky Way is really the only galaxy we have where we can study how supermassive black holes interact with little ones because we simply can’t see their interactions in other galaxies."

THE SEARCH
"The researchers used Chandra data to search for X-ray binaries – systems where a black hole is locked in a close orbit with a star and is pulling matter from the star, resulting in X-ray emission – near Sagittarius A*."

THE CENTER
Our "...galactic center is already known to be inhabited by a supermassive black hole, with some 4 million times the sun’s mass. Astronomers call this behemoth Sagittarius A."

"Sagittarius A* is about 26,000 light-years from Earth. The scientists said that – at this distance – only the brightest X-ray binaries containing black holes are likely to be detectable. Therefore, they said:"

THE SWARM
"...the detections in this study imply that a much larger population of fainter, undetected X-ray binaries — at least 300 and up to 1,000 — containing stellar-mass black holes should be present around Sagittarius A*."

Support Tahoe to Whitney

The Tahoe to Whitney Trail Guide and Magazine are walked, written, funded, and supported by my efforts, with the help of kindred spirits and my sister.

We offer valuable Trail Guide, Skills, Weather, News and Analysis.

My goal is to get you out to see your natural and social potential. Help me keep this unique resource accessible and expanding towards its potential. We've a lot of miles to cover ahead...

I NEED HELP!
If you feel these efforts are valuable, I'm cordially inviting you to support them, here:

 

 

I am currently working towards publishing the completed guide between Tahoe & Yosemite as an e-book, while converting this "blog" to a fine magazine format. You will like the results! Help Tahoe to Whitney reach its potential!
