Webb Telescope Sheds Light on the Early Universe
Webb Telescope , Sheds Light , on the Early Universe.
Gizmodo reports that NASA's Webb
Space Telescope has taken aim at
the barred spiral galaxy EGS23205.
.
The distant galaxy will reportedly increase
our understanding of the young universe and
how the first stars and galaxies took form.
Previously, NASA's Hubble Telescope also captured images
of the galaxy.
However, Webb's sharper images reveal
a stellar bar reaching out from the galactic center.
.
The bars hardly visible in Hubble data
just popped out in the JWST image, showing
the tremendous power of JWST to see
the underlying structure in galaxies, Shardha Jogee, astronomer at UT Austin
and co-author of the research, via Gizmodo.
A stellar bar is a massive galactic
cross-section of countless stars, which
plays a crucial role in galactic evolution.
.
They help to push gas toward the galaxy's
center, fueling star formation and feeding
the central supermassive black hole.
.
The Webb Telescope has been targeting some of
the earliest galaxies ever seen, which appear as they
were several hundred million years after the Big Bang.
The images captured of EGS23205
are snapshots of the galaxy
about 11 billion years ago.
.
In October, NASA's new $10 billion observatory captured images of the Pillars of Creation, massive plumes of dust and gas found in the Eagle Nebula.
The same month, Webb produced an image
of merging galaxies approximately
270 million light-years away from Earth.
NASA Reestablishes , Connection With Distant , Voyager 1 Space Probe.
The news comes after engineers at
the agency worked for months
attempting to fix the 46-year-old probe.
In December, NASA's Jet Propulsion Laboratory (JPL)
said that the probe, now a staggering 15 billion miles
away from Earth, was transmitting gibberish code. .
On April 23, the JPL announced that
the team was once again receiving
usable data from the spacecraft.
Currently, the probe is only
transmitting data regarding the status
of the ship's engineering systems.
The next step is to enable
the spacecraft to begin
returning science data again, JPL statement, via 'The Guardian'.
'The Guardian' reports that Voyager 1 has been in
operation for nearly half a century after launching
in 1977 with the goal of studying Jupiter and Saturn.
In August of 2012, Voyager crossed into
interstellar space, becoming the first
human-made object to leave the solar system.
The probe is currently traveling at a staggering
36,800 miles per hour through space.
NASA plans to collect data from the two
Voyager spacecraft for a few more years,
but the space agency expects to lose
contact with the probes within the next decade

NASA has unveiled striking images capturing the extensive flooding in the UAE following the recent torrential rainfall. Describing it as a "slow-moving storm," NASA highlighted the unprecedented deluge that inundated the Gulf states, surpassing a year's worth of rainfall in some regions. According to the UAE's meteorological department, the country received a staggering 6.04 billion cubic metres of rain last week, nearly equivalent to its annual precipitation of 6.7 billion cubic metres. This remarkable event underscores the magnitude of the weather phenomenon that swept across the region.

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.

The Reason Why, Insects Are Attracted , to Artificial Light.
Gizmodo reports that
researchers believe they finally know
why insects seem to be drawn to lights.
New data suggests that bugs
are not attracted to the light,
as is commonly believed.
Rather, researchers now believe that
based on insects' use of light sources to
orient flight, artificial lights disorient bugs.
The team's findings were published
in the journal 'Nature Communications.'.
This has been a prehistorical
question. In the earliest writings,
people were noticing this around fire. , Jamie Theobald, Biologist at Florida International
University and co-author of the study, via Gizmodo.
It turns out all our
speculations about why it
happens have been wrong, Jamie Theobald, Biologist at Florida International
University and co-author of the study, via Gizmodo.
Researchers note that insects'
"seemingly erratic" flying patterns
are really their failed attempts
to understand the artificial light. .
Rather than steering toward the light, bugs were
seen turning their dorsum, or their backs,
toward the light, attempting to steer by it.
Under natural sky light, tilting
the dorsum towards the brightest
visual hemisphere helps maintain
proper flight attitude and control, Study authors, via Gizmodo.
Near artificial sources,
however, this highly conserved
dorsal-light-response can produce
continuous steering around
the light and trap an insect, Study authors, via Gizmodo
