2023 was a great year with both Hubble, Webb and others making new discoveries and producing amazing images. We start out with an update on the DART asteroid collision we covered last year. Staying inside the Solar System, we cover the Parker Solar Probe’s journey through the Suns corona. Moving beyond the Solar System, we’ll see molecular clouds, brown dwarfs, Herbig-Haro objects, and take a deeper look into the Crab and Cassiopeia nebulas. We’ll then do a little astrochemistry in the Iris Nebula. Moving beyond our galaxy, we cover dwarf galaxies, a runaway black hole, a possible intermediate mass black hole, intergalactic stars, and some of the oldest galaxies ever found. We’ll end with the first release images from ‘Euclid,” our newest space telescope.

in 2023 a team of astronomers detected a
possible intermediate Mass black hole of
roughly 800 solar masses at the center
of the M4 globular star
cluster in our how fast is it video book
chapter on black holes we covered how no
intermediate Mass black holes have been
confirmed to date but here's one that
might be they examined 12 years worth of
M4 observ from Hubble and resolved
pinpoint
Stars the suspected object can't be seen
but its mass is calculated by studying
the motion of stars caught in its
gravitational
field the black hole has an event
horizon that is a little more than half
the diameter of our
moon this is a simulation of the Motions
of stars around the suspected black hole
after the zoom into M4 the center of the
cluster where the suspected black black
hole resides is highlighted by a red
X the red circle has a radius of just
under half a
lightyear it delineates the sphere of
influence of the intermediate Mass black
hole it should be noted that although an
intermediate Mass black hole can explain
these star movements other possibilities
exist such as a cluster of Stellar Mass
black holes or neutron
stars so by the end of 2023 there has
still not been a single confirmed
imbh in the future the webspace
telescope might help resolve this
question by improving the star count and
velocities near the
center
