Webb Telescope Spots Frozen Water and Molecules in Distant Molecular Cloud
Webb Telescope Spots , Frozen Water and Molecules, in Distant Molecular Cloud .
Gizmodo reports that NASA's Webb telescope has
detected water ice and frozen complex molecules
about 630 light-years from Earth in a molecular cloud.
According to the team,
the freezing observations are the
deepest, coldest yet seen in such a cloud.
A molecular cloud is a huge, dusty region of space that
typically serve as stellar nurseries as they contain
all of the ingredients necessary for stars to form.
.
These clouds are also home to organic molecules.
.
In 2022, scientists analyzing a molecular cloud at the center of our galaxy found evidence of the building blocks
of RNA, a molecule shared by all living cells.
The most recent frozen molecular
cloud contained water, methane, ammonia
and complex molecules such as methanol.
The team's findings were
published on January 23 in
the journal 'Nature Astronomy.'.
Gizmodo reports that the observation
of molecular clouds comes as
part of Webb's Ice Age project.
.
Our results provide insights into the initial,
dark chemistry stage of the formation of ice
on the interstellar dust grains that will
grow into the centimeter-sized pebbles
from which planets form in disks, Melissa McClure, Astronomer at Leiden
Observatory in the Netherlands, via 'Gizmodo'.
We simply couldn’t have observed these
ices without Webb.
Webb’s exquisite
sensitivity was necessary to detect
the starlight and therefore identify
the ices in the molecular cloud, Klaus Pontodippan, Webb project scientist
and a co-author of the research, via 'Gizmodo'
Boeing called off its first astronaut launch, ferrying two NASA test pilots to the International Space Station, because of a valve problem on its Starliner capsule. But if engineers find a solution quickly, another countdown could be expected in the next 24-hours.

Scientists Question Claim , That T. Rex Was as Smart, as Modern Monkeys.
'Gizmodo' reports that a team of researchers
recently investigated claims that the Tyrannosaurus rex
could have been as smart as monkeys.
Last year, a paper was published in the journal
'Comparative Neurology,' which claimed that theropods like
Tyrannosaurus rex had a “monkey-like” numbers of neurons.
According to that paper, this would have made
the Tyrannosaurus rex "not only giant but also
long-lived and endowed with flexible cognition.”.
The new paper specifically referenced the previous paper
and argues that theropods probably had “significantly
lower neuron counts than previously proposed.".
According to the team, neuron count
and brain size are “flawed” proxies for
measuring an ancient species’ intelligence.
We argue that it’s not good
practice to predict intelligence
in extinct species when neuron
counts reconstructed from
endocasts are all we have to go on, Kai Caspar, a biologist at Heinrich Heine University
Düsseldorf and the study’s lead author, via 'Gizmodo'.
The possibility that T. rex might
have been as intelligent as a baboon
is fascinating and terrifying,
with the potential to reinvent
our view of the past, Darren Naish, Paleozoologist at the University of
Southampton and co-author of the paper, via 'Gizmodo'.

But our study shows how
all the data we have is against
this idea. They were more
like smart giant crocodiles,
and that’s just as fascinating, Darren Naish, Paleozoologist at the University of
Southampton and co-author of the paper, via 'Gizmodo'.
'Gizmodo' reports that even if Tyrannosaurus rex
wasn't as intelligent as a modern monkey,
it was still a terrifying creature. .
The fearsome predator also has an outsized
presence in popular culture, leading theropods
to attract a high degree of interest.

Astronomers Say , Neutron Jet Emissions , Travel at Relativistic Speeds.
Gizmodo reports that new research suggests that
the dense remains of massive stars propel jets of gas and
dust at speeds of hundreds of millions of miles per hour.
Neutron stars are the stellar remains of
some of the densest objects in the universe. .
According to new research, neutron star jets
can travel up to 70,836 miles per hour,
just over one-third the speed of light. .
Relativistic effects like time dilation and length
contraction are believed to occur at speeds
exceeding just one-tenth the speed of light. .
James Miller Jones, , an astrophysicist at Curtin University in
Australia and co-author of the research, .
notes that neutron stars are, "so dense that they can pull material off
the surface of a nearby companion star.".
That gas spirals down onto the surface
of that neutron star where it gets very,
very hot and dense. Once enough of it
builds up nuclear fusion reactions
start to happen on the surface, James Miller Jones, astrophysicist at Curtin University
in Australia and co-author, via 'Gizmodo'.
Using the Australia Telescope Compact Array and the
International Gamma-Ray Astrophysics Laboratory, researchers found that thermonuclear explosions on
distant stars kickstart these high-speed jet emissions. .
When these explosions occurred, they generated
high-speed jets and bright X-rays which made
it possible for researchers to measure speeds. .
The findings suggest that the staggering
speed of these emissions is close to escape
speed, or the needed velocity for material to
escape the neutron star's gravitational speed. .
Gizmodo reports that the team's results will inform
future models of jet formation and could help reveal
some of the most extreme physics in the universe.

AT&T Confirms Data Breach , Affected 73 Million Customers.
73 million current and former
AT&T customers have had their sensitive
data compromised in a hack that some outlets
say dates back to 2021, Gizmodo reports.
The data, which includes social security numbers, email addresses, birthdates, phone numbers and AT&T account information, .
was located two weeks ago in a data
set released on the dark web.
It's not clear if it was AT&T's systems that were breached or if the information was stolen from one of the company's vendors.
Currently, AT&T does not have evidence
of unauthorized access to its systems
resulting in exfiltration of the data set, AT&T, via statement.
The company is communicating
proactively with those impacted and
will be offering credit monitoring at
our expense where applicable, AT&T, via statement.
As a precaution, AT&T has reset the
passcodes of its current customers. .
The company will be reaching out to customers whose information has been compromised. .
AT&T advises those who are worried about their accounts to monitor activity and credit reports.

Everyone being held hostage in a town in central Netherlands is now free and a suspect is in custody, Dutch police said Saturday, after an ordeal that lasted several hours. "The last hostage has just been released. One person has been arrested. We cannot share more information at this time," announced police on X, formerly Twitter. Police in central Netherlands reported that on March 30, several individuals were taken hostage in a town, prompting evacuations of nearby residences and the closure of the town centre. Authorities earlier stated that, at present, there is no indication of a "terrorist motive" behind the incident in Ede.
