A new telescope shows the center of the Milky Way in dazzling, fiery detail
MeerKAT is producing brilliant images of the super massive black hole that is at our galaxy’s center.
There is a new radio telescope up and running based in Karoo, South Africa. The MeerKAT (Karoo Array Telescope), as it’s named, operated by the South African Radio Astronomy Observatory, is already producing brilliant images of the super massive black hole that is at our galaxy’s center, 25,000 light years away.
That center is obscured from view when using traditional methods of observation; it’s behind the constellation Sagittarius, where clouds of gas and dust hide it from view. However, MeerKAT's radio wavelengths penetrate the obscuring dust and open a window into this distinctive region and its black hole.
The “filaments” that you see in the image above are not yet fully understood, after being first discovered in the 1980s, but they only exist near that central black hole. The other objects are remnants of supernovae and star-forming regions, near dead center of the Milky Way.
“We wanted to show the science capabilities of this new instrument,” said Fernando Camilo, chief scientist of the South African Radio Astronomy Observatory (SARAO), which built and operates MeerKAT. “The center of the galaxy was an obvious target: unique, visually striking and full of unexplained phenomena—but also notoriously hard to image using radio telescopes.”
"Although it’s early days with MeerKAT, and a lot remains to be optimized, we decided to go for it—and were stunned by the results,” Camilo continued.

This is not the first image by MeerKAT; it captured an image two years ago of an area that scientists previously thought only held about 70 galaxies; MeerKAT captured over 1,300.

What can 3D printing do for medicine? The "sky is the limit," says Northwell Health researcher Dr. Todd Goldstein.
- Medical professionals are currently using 3D printers to create prosthetics and patient-specific organ models that doctors can use to prepare for surgery.
- Eventually, scientists hope to print patient-specific organs that can be transplanted safely into the human body.
- Northwell Health, New York State's largest health care provider, is pioneering 3D printing in medicine in three key ways.
The phenomenon that makes our favourite drinks bubbly is, alarmingly, the same one that causes decompression sickness in divers. Why do we still love it?
As Game of Thrones ends, a revealing resolution to its perplexing geography.
- The fantasy world of Game of Thrones was inspired by real places and events.
- But the map of Westeros is a good example of the perplexing relation between fantasy and reality.
- Like Britain, it has a Wall in the North, but the map only really clicks into place if you add Ireland.
