An
international
team
of
researchers,
led
by
scientists
from
Stockholm
University’s
Department
of

Astronomy,
has
discovered
a
higher
number
of
black
holes
in
the
early
universe
than
was
previously
recorded.
Using
the

NASA
Hubble
Space
Telescope,
this
team
found
black
holes
among
faint
galaxies
formed
shortly
after
the
Big
Bang
event.
These
findings
may
help
scientists
understand
how
supermassive
black
holes
were
formed
and
the
role
they
play
in
the
evolution
of
galaxies.
Hubble’s
data
was
gathered
from
years
of
observations
of
the
Ultra
Deep
Field
region.

Supermassive
Black
Holes
Found
in
Distant
Galaxies

One
of
the
key
discoveries
was
the
presence
of
supermassive

black
holes
at
the
centre
of
several
galaxies
formed
less
than
a
billion
years
after
the
big
bang.
These
black
holes
have
masses
equivalent
to
billions
of
suns,
far
larger
than
what
scientists
initially
predicted.

Alice
Young,
a
PhD
student
from
Stockholm
University
and
a
co-author
of
the

study
published
in
The
Astrophysical
Journal
Letters,
noted
that
these
black
holes
either
formed
as
extremely
massive
objects
or
grew
rapidly
in
the
early
universe.

Observing
Black
Holes
through
Variations
in
Brightness

The
research
team
re-photographed
the
same
region
over
several
years
using
Hubble,
allowing
them
to
measure
changes
in
galaxy
brightness.
These
changes
are
signals
of
black
holes
flickering
as
they
swallow
material
in
bursts.
Matthew
Hayes,
lead
author
and
professor
at
Stockholm
University,
explained
that
these
findings
help
improve
models
of
how
both
black
holes
and
galaxies
grow
and
interact
over
time.

Implications
for
Understanding
Galaxy
Formation

The
research
suggests
black
holes
likely
formed
from
the
collapse
of
massive
stars
in
the
universe’s
first
billion
years.
These
findings
provide
a
clearer
picture
of
black
hole
and
galaxy
evolution,
which
can
now
be
better
understood
through
more
accurate
scientific
models.

NASA‘s
Europa
Clipper
mission
is
on
track
for
its
scheduled
October
10
launch,
aiming
to
explore
Jupiter’s
icy
moon,

Europa.
Scientists
believe
Europa
could
be
one
of
the
most
promising
places
to
find
the
conditions
for
life
beyond
Earth.
The
spacecraft
will
travel
1.8
billion
miles
(2.9
billion
kilometres)
to
study
whether
the
moon’s
icy
surface
hides
a
vast
ocean
beneath,
which
could
harbour
the
right
conditions
for
life.
The
mission,
however,
faces
challenges
due
to
intense
radiation
around
Jupiter.

Mission
preparations
and
potential
challenges

NASA’s
Europa
Clipper
will
launch
aboard
a

SpaceX
Falcon
Heavy
rocket
from
Kennedy
Space
Center
in
Florida.
Despite
concerns
over
some
defective
transistors
on
the
spacecraft,
the
mission
remains
on
schedule.
The
spacecraft
will
arrive
at
Jupiter
in
April
2030
and
conduct
49
flybys
of
Europa,
gathering
scientific
data
about
the
moon’s
environment.

Jordan
Evans,
Project
Manager
at
NASA’s
Jet
Propulsion
Laboratory
(JPL),

told Space.com that
intense
radiation
around
Jupiter
is
a
significant
challenge.
The
spacecraft
will
be
exposed
to
radiation
levels
equivalent
to
millions
of
chest
X-rays
during
each
flyby.
The
team
has
developed
a
trajectory
to
minimise
exposure,
allowing
the
spacecraft
to
complete
its
mission
and
return
valuable
data
to
Earth.

Investigating
Europa’s
icy
shell
and
subsurface
ocean

Europa
Clipper
will
use
its
suite
of
scientific
instruments
to
estimate
the
thickness
of
Europa’s
icy
crust
and
study
its
surface
for
signs
of
geological
activity.
Ann
Allen,
Deputy
Project
Scientist
at
the
National
Oceanographic
and
Atmospheric
Administration
(NOAA),
explained
that
the
spacecraft
will
search
for
organic
compounds,
though
it
will
not
directly
search
for
life.
Instead,
it
will
focus
on
finding
the
ingredients
that
could
make
life
possible
beneath
the
ice.

The
mission
is
designed
to
last
four
years
and
could
reveal
important
information
about
Europa’s
subsurface
ocean,
setting
the
stage
for
future
exploration.

Recent

astronomical
discoveries
suggest
that
our
solar
system
could
be
much
larger
than
previously
thought,
with
the
potential
existence
of
a
second

Kuiper
Belt
beyond
the
one
we
know.
Using
the
powerful
Subaru
telescope,
astronomers
have
spotted
11
new
objects
orbiting
far
beyond
the
known
Kuiper
Belt,
indicating
the
presence
of
a
second
belt,
tentatively
named
“Kuiper
Belt
2.”

What
is
the
Kuiper
Belt?

The
Kuiper
Belt
is
a
distant
region
of
our
solar
system
located
beyond
Neptune,
stretching
from
about
33
to
55
astronomical
units
(AU).
It
contains
icy
bodies
and
comets
that
orbit
the
sun,
and
it
was
the
primary
target
for
NASA’s
New
Horizons
mission,
which
famously
explored
Pluto
in
2015.

Beyond
the
known
Kuiper
Belt
lies
a
vast,
unexplored
region
of
space,
where
scientists
now
believe
more
mysterious
objects
may
exist.

New
Discoveries
Beyond
the
Kuiper
Belt

Using
Subaru’s
Hyper
Suprime-Cam
(HSC),
scientists

found
239
Kuiper
Belt
objects
since
2020.
However,
the
most
significant
discovery
was
11
objects
located
between
70
and
90
AU
from
the
sun,
suggesting
the
existence
of
a
second,
more
distant
belt.
This
new
belt
could
extend
as
far
as
13.5
billion
kilometers
(8.4
billion
miles)
from
the
sun.

Notably,
there
is
a
gap
between
55
and
70
AU
where
no
objects
have
been
found,
further
supporting
the
idea
of
a
distinct
second
belt.

Implications
for
Our
Understanding
of
the
Solar
System

This
discovery
could
reshape
our
understanding
of
how
the
solar
system
formed.
For
years,
scientists
believed
that
the
Kuiper
Belt
was
unusually
small
compared
to
similar
belts
found
in
other
planetary
systems.
However,
the
identification
of
Kuiper
Belt
2
suggests
that
our
solar
system
may
be
more
typical
and
that
its
primordial
nebula
was
larger
than
initially
thought.

The
discovery
of
Kuiper
Belt
2
is
still
under
investigation,
but
it
hints
at
the
possibility
of
more
dwarf
planets
and
even
the
long-theorized
Planet
Nine.
As
astronomers
continue
to
observe
these
distant
objects,
we
may
uncover
even
more
surprises
in
the
outer
reaches
of
our
solar
system
as
a

preprint.

The
launch
of

SpaceX
Crew-9,
a
significant
mission
to
the
International
Space
Station
(ISS),
has
been
delayed
to
September
26,
2024.
This
change
allows
teams
to
complete
final
prelaunch
procedures
and
ensure
all
equipment
is
prepared.
The
delay
also
accounts
for
weather
conditions
and
other
prelaunch
checks.
The
launch,
initially
set
for
August
18,
will
now
occur
no
earlier
than
2:05
p.m.
EDT
(1805
GMT)
from
Space
Launch
Complex-40
at
Cape
Canaveral
Space
Force
Station
in
Florida.

Mission
Details
and
Crew

SpaceX
Crew-9
is
now
scheduled
to
carry
only
two
astronauts:

NASA
astronaut
and
U.S.
Space
Force
commander
Nick
Hague,
and
Russian
cosmonaut
Aleksandr
Gorbunov.
Hague
is
set
to
become
the
first
active
Space
Force
Guardian
to
fly
into
space.

Originally,
the
mission
was
to
include
NASA
astronauts
Zena
Cardman
and
Stephanie
Wilson,
but
their
seats
will
be
occupied
by
mass
simulators.
Cardman
and
Wilson
will
be
considered
for
future
missions
to
the
ISS.

Impact
of
the
Delay

The
delay
follows
issues
with
Boeing’s
Starliner
spacecraft,
which
affected
the
planned
return
of
ISS
astronauts
Butch
Wilmore
and
Suni
Williams.
The
astronauts,
who
arrived
at
the
ISS
aboard

Starliner,
will
now
return
to
Earth
on
SpaceX
Crew
Dragon.
This
adjustment
ensures
that
their
return
is
managed
safely
and
effectively.

The
Crew-9
mission’s
delay
provides
NASA
with
the
necessary
time
to
ensure
that
all
systems
are
functioning
properly
and
that
the
launch
will
proceed
smoothly.

Looking
Ahead

The
new
launch
date
allows
for
better
preparation
and
ensures
that
Crew-9’s
mission
objectives
are
met.
With
Crew-9
set
to
arrive
at
the
ISS,
the
spacecraft
will
also
provide
a
return
route
for
the
Starliner
astronauts.
This
adjustment

highlights
the
ongoing
efforts
to
maintain
ISS
operations
and
crew
rotations,
ensuring
that
the
space
station
remains
fully
operational
and
continues
to
support
scientific
research
and
international
collaboration.
