Garching

- Interesting

research results

from

Garching

: South of the

Milky Way

, the German X-ray telescope "eRosita" has discovered a huge gas bubble.

This is the result of the

first complete sky survey

with the X-ray telescope, report researchers from the Max Planck Institute for Extraterrestrial Physics (MPE) in Garching.

Garching: Researchers discover huge gas bubbles near the Milky Way - amazing explanation

The most likely

explanation

for the structure of hot gas:

shock waves

.

These come from earlier, high-energy eruptions inside the Milky Way.

A similar structure in the northern sky, the so-called

north polar spur, has

long been known

.

So far, however, it has been suggested that this could have come from a nearby supernova explosion.

But was this assumption wrong all along?

The

scientists

explain: Taken together, the

north and south structures

now show that the cause is more likely to be in the

center of the galaxy

.

In their shape they are reminiscent of an hourglass below and above the galactic disk.

The cause of this could also be the

black hole

.



MPE researcher Michael Freyberg: "Thanks to its sensitivity as well as energy and angular resolution," eRosita "can map the entire X-ray sky at a previously unattainable depth and thus clearly identify the southern bubble." Every six months the

telescope

scans the

entire sky

.

The scientists can then use the data to

search for

large-scale structures

.

Garching: Telescope has been sending data to researchers since July 2019

In July 2019 Russian carrier rocket with "eRosita" and a Russian telescope aboard the was

spaceport

Baikonur in Kazakhstan to

start all

.

Since then, the

telescope has been

sending

data

.

This results in

maps of the sky

, which depict the universe and its development.



The

astronomers

assume that with “eRosita” they will find around 100,000 galaxy clusters and several million active black holes in the centers of the galaxies.

Since light from distant galaxies travels a long time, the

telescope

can

look back

up to

six billion years

.

Back to earth: several tens of thousands of euros were damaged in a fire in a bakery in Dirnismaning.

The cause of the fire seems to have already been clarified.

And living space for 1,650 people is to be created in Hochbrück.

The plans for the new “Am Schleissheim Canal” quarter have now been presented to the city council.
