Scientists Discover the Oldest Black Hole Ever Observed
Scientists Discover the Oldest , Black Hole , Ever Observed.
In 2016, the Hubble Space Telescope spotted
GN-z11, the most distant galaxy ever identified,
having formed 13.4 billion years ago,
just 400 million years after the Big Bang.
However, GN-z11 presented astronomers with a puzzling
problem, as the galaxy appeared to be much brighter,
or densely packed with stars, than it should have been.
.
NPR reports that a team of scientists, using the powerful James Webb Space Telescope, believe they may
have solved the mystery of the ancient galaxy.

NPR reports that a team of scientists, using the powerful James Webb Space Telescope, believe they may
have solved the mystery of the ancient galaxy.
.
Roberto Maiolino, an astrophysicist at the University
of Cambridge, and his colleagues believe that
a massive black hole is responsible for the anomaly.
.
While the black hole itself, which is
about 1.6 million times the mass of
our Sun, is unable to emit any light.
Maiolino and his team suggest that all the material
being drawn into the black hole may be hot and bright
enough to create GN-z11's intense radiance.
This black hole is essentially
eating the [equivalent of] an entire
Sun every five years.
It's actually
much higher than we thought could
be feasible for these black holes, Roberto Maiolino, astrophysicist at
the University of Cambridge, via NPR.
According to Maiolino, the existence of this ancient
black hole calls into question the origin of black holes
and the processes by which they feed and grow.
The team believes that supermassive black holes may
have been generated by the collapse of huge clouds
of primordial gas in the aftermath of the Big Bang.
Another alternative explanation could be that
a sea of smaller black holes merged and
consumed a vast amount of matter that
spurred unexpectedly quick growth.
.
The team also believes that this black hole has
stunted the growth of GN-z11, impeding star
formation and ultimately strangling the galaxy.
Advocates Fight For Those , Sickened By US Nuclear Testing , Program on Capitol Hill.
On June 7, the federal Radiation Exposure Compensation
Act (RECA) program is set to expire, ending a lifeline
for families sickened by the country's nuclear testing. .
On June 7, the federal Radiation Exposure Compensation
Act (RECA) program is set to expire, ending a lifeline
for families sickened by the country's nuclear testing. .
NPR reports that advocates have gathered
on Capitol Hill to fight for so-called atomic
veterans and save the RECA program.
Over the past year, multiple bipartisan
bills were approved by the Senate to
reauthorize and expand the program. .
Those bills stalled out in the House,
due to some Republicans objecting
to the cost of the program. .
According to sponsors of the bills, those concerns
were addressed by reducing the initial 2023 estimate
of $143 billion down to between $50 and $60 billion. .
NPR reports that RECA has provided payments up to
$75,000 to those sickened by the nuclear testing
program, totaling $2.7 billion to over 400,000 recipients. .
One of the groups fighting to have
the program extended is the
Tularosa Basin Downwinders Consortium. .
The group works to raise awareness of illnesses
linked to Trinity, the government's code word for
the first nuclear bomb test, which took place in 1945.
Martinez White, a member of the group,
says fallout from those tests resulted in at
least six cases of cancer in her family of ten. .
I would often go home for
funerals and everybody in
Tularosa was dying of cancer.
We knew something was very weird. , Martinez White, Tularosa Basin
Downwinders Consortium member, via NPR.
There's no industry in the whole
Tularosa Basin but for White Sands
Missile Range, where the
Trinity bomb was detonated, Martinez White, Tularosa Basin
Downwinders Consortium member, via NPR

Astronomers Witness , Merger of 2 Black Holes, From the 'Cosmic Dawn'.
'The Independent' reports that NASA's
Webb Space Telescope has made the most
distant detection of merging black holes. .
Two gigantic black holes and the galaxies that they stood
at the center of merged together just 740 million years
after the universe was formed in the Big Bang.
One of the black holes is a staggering 50 million
times larger than our Sun, and the other
is believed to be a similar gigantic size. .
Astronomers have long wondered how supermassive black holes are so big. .
Lead author Hannah Ubler of the University of Cambridge
says the findings suggest that mergers like this ancient
example show how black holes are able to grow so rapidly.
According to Ubler, the latest Webb
discovery also suggests that black holes
have been merging since the "cosmic dawn.".
Massive black holes
have been shaping
the evolution of galaxies
from the very beginning, Hannah Ubler, lead author from the University
of Cambridge, via 'The Independent'.
In 2021, NASA launched Webb, intended
to replace the Hubble Space Telescope.
Webb is the largest and most powerful
observatory ever launched into space. .
The joint U.S.-European project surveys
the universe from a vantage point located
about 1 million miles away from Earth.

New Study Supports Evidence , That Summer 2023 Was the , Hottest in Over 2 Millennia.
According to an analysis of tree rings going all the
way back to year one, 2023 was the hottest summer
in the Northern Hemisphere in over 2000 years. .
According to an analysis of tree rings going all the
way back to year one, 2023 was the hottest summer
in the Northern Hemisphere in over 2000 years. .
HuffPost reports that scientists analyzed over
10,000 tree rings to determine temperature
levels dating back two millennia.
The team from the University of Cambridge and the
Johannes Gutenberg University Mainz found that the
summer of 2023 was 2.2 degrees Celsius above average.
The temperature from June to August 2023 was
compared to average temperatures from the
same period between year one and 1890. .
When you look at the long sweep
of history, you can see just how
dramatic recent global warming is. , Ulf Büntgen, Cambridge Department of Geography, via HuffPost.
2023 was an exceptionally hot
year, and this trend will continue
unless we reduce greenhouse
gas emissions dramatically, Ulf Büntgen, Cambridge Department of Geography, via HuffPost.
HuffPost reports that 2023 saw global record-breaking
ocean temperatures, widespread wildfires
across the continent and scorching heat in cities.
It’s true that the climate is always
changing, but the warming in 2023,
caused by greenhouse gases, is additionally
amplified by El Niño conditions, so we end up
with longer and more severe heat waves
and extended periods of drought, Jan Esper, professor at the Johannes Gutenberg University Mainz
and lead author of the paper, via HuffPost.
