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.

A strange weakness in the Earth's protective magnetic field is growing and possibly splitting, shows data.
- "The South Atlantic Anomaly" in the Earth's magnetic field is growing and possibly splitting, shows data.
- The information was gathered by the ESA's Swarm Constellation mission satellites.
- The changes may indicate the coming reversal of the North and South Poles.

Researchers detect a large lake and several ponds deep under the ice of the Martian South Pole.
- Italian scientists release findings of a large underground lake and three ponds below the South Pole of Mars.
- The lake might contain water, with salt preventing them from freezing.
- The presence of water may indicate the existence of microbial and other life forms on the planet.

"Nothing but naked people: fat ones, thin ones, old, young…"
"The Yellow Sands", 1888, John Reinhard Weguelin; source: Wikimedia Commons<h3>Naked revolution</h3><p>Yet long before anyone knew about beach fashion, naturism was trendy. Bathing naked in the sea was going on in England as early as 1840. However, during the reign of Queen Victoria, this pleasure was outlawed. But it popped up again among the conservative Germans. In 1898, the first Naturist Club was founded in Essen and in 1900 the Wandering Birds group (<em>Wandervögel</em>) was scouring the country for uninhabited places and naked sunbathing. In the same year, Heinrich Pudor wrote <em>The C</em><em>ult of </em><em>the </em><em>Nud</em><em>e</em>, winning the hearts of contemporary supporters of naturism.</p><p>In the 1920s, on the back of this, members of the Movement for Natural Healing (<em>Naturheilbewegung</em>) organized naked sunbathing for the improvement of health. Persuaded by Pudor's theory of the healing properties of the sun and wind, which could be absorbed through the skin, they launched the naked revolution.</p><p>Pudor's book became the naturists' manifesto and soon after, not far from Hamburg, the Free Body Culture (<em>Freikörperkultur</em>, or FKK) movement was founded. This spread through other German centres and brought together thousands of people. The FKK still operates under the same name today.</p><p>The cult of the naked body even wrote itself into the ideology of fascist Germany, which advocated a pure, Aryan race. But in 1933, Hermann Göring issued an order that defined nudity as "the greatest threat to the German soul" and, with that, criminalized naturist organizations. But this wasn't the end of the movement. The naturists went underground, continuing their activities under the guise of improving physical fitness.</p><p>In 1936, the idea was even floated of having a naturist display to open the Berlin Olympic Games. It was quickly dropped. Despite this, in 1939 the naturists managed to organize their own Games in the Swiss village of Thielle.</p>
