astronomers have made an exciting
0:02
discovery about a small black hole
0:07
105 this black hole is sucking in gas
0:10
and dust and astronomers have spotted
0:13
strange changes in the jet of Highly
0:16
magnetic plasma that it shoots out these
0:19
changes happen very quickly within a
0:22
fraction of a second and were detected
0:25
by the 500 M aperture spherical radio
0:28
telescope that is f St in
0:32
China GRS 1915 plus 105 is a unique
0:36
object consisting of a regular star
0:38
orbiting a stellar black hole which
0:41
formed after a massive star
0:44
died as the star moves around the black
0:47
hole some of its material gets pulled in
0:50
but not all of it gets swallowed instead
0:54
some of the material gets shot out as a
0:57
jet from the black holes poles the the
1:00
astronomers think that the changes in
1:02
the Jet's energy might be because the
1:05
black hole's rotation is not aligned
1:08
with the matter it is eating this
1:11
misalignment causes the jet to wobble
1:14
like a spinning top when the jet points
1:17
away its energy drops but then it
1:19
returns to normal when the system
1:21
rotates back the observations show that
1:24
The Peculiar signal in the jet has a
1:26
rough period of 0.2 seconds and it only
1:30
appears under special conditions the
1:32
researchers were lucky enough to observe
1:35
this signal twice in January 2021 and
1:38
June 2022 the cause of these
1:41
oscillations remains a mystery but
1:44
scientists believe that one possible
1:46
explanation is the Precision of the jet
1:50
this means that the jet Direction
1:52
regularly points towards different
1:54
directions and returns to the original
1:57
Direction every 0.2 seconds further
2:00
research is needed to fully understand
