The researchers at the Max Planck Institute in Garching have the result of a first complete sky survey.
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.
