Galaxy Cluster That Warps Space-Time Used by Scientists to Find 2 Distant Galaxies
Galaxy Cluster That Warps Space-Time , Used by Scientists to Find , 2 Distant Galaxies.
Business Insider reports that astronomers have used a
galaxy cluster that warps the fabric of space-time to help
uncover two of the most distant galaxies ever discovered.
.
A team at Penn State used NASA's new James Webb
Space Telescope to find two galaxies hidden by
Pandora's Cluster, otherwise known as Abell 2744.
.
According to Space.com, the cluster
of galaxies is located about
3.5 billion light-years from Earth.
The mass of those galaxies creates a gravitational
lens, which warps space-time and magnifies
light coming from far beyond the phenomenon.
.
This naturally occurring magnifying effect helped
astronomers glimpse two never-before-observed
galaxies, a staggering 33 billion light-years away.
The light from these galaxies
is ancient, about three times
older than the Earth, Joel Leja, a member of the Penn State research team, via Business Insider.
According to the research team, while three
other distant galaxies have been detected in
the past, these new examples are far larger.
Business Insider reports that the newly-discovered
galaxies also have a unique shape, which the team
described as like a "peanut" and a "fluffy ball.".
The reason for the galaxies' odd shapes
remains unknown, as they are believed to
have formed from similar materials.
These early galaxies are like beacons,
with light bursting through
the very thin hydrogen gas
that made up the early universe, Joel Leja, a member of the Penn State research team, via Business Insider.
It is only by their light that we can begin
to understand the exotic physics that
governed the galaxy near the cosmic dawn, Joel Leja, a member of the Penn State research team, via Business Insider
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. .

Contractor Warns of , Potential Catastrophe if NASA , Goes Ahead With Scheduled Launch.
IEN reports that a NASA contractor has publicly
urged the space agency to reconsider an
upcoming launch, warning it could end in disaster.
The news comes after the initial launch
of Boeing's Starliner was scrapped as
the result of a leaky valve just last week. .

NASA has plans to attempt
another launch later this week. .

The company issued a press release
warning that a second launch
attempt could end in catastrophe. .
The statement from ValveTech
President Erin Faville called for NASA
to re-double safety checks and protocols. .
The failed launch last week would have been
the first human space flight for Boeing but was
scrubbed after a faulty valve was discovered. .
The Associated Press reported that the fluttering oxygen
pressure-relief valve on United Launch Alliance’s Atlas
rocket may have exceeded its 200,000 lifetime cycles. .
The ValveTech statement questions how
NASA, Aerojet and Boeing could have... .
... "qualified this valve for the mission
without proper supporting data or
previous history or legacy information.".
According to ValveTech, this , "goes against aerospace-industry
qualification protocols established by NASA."

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.

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

NOAA Issues Rare , Warning Following Powerful , Solar Event.
CBS reports that a severe G4 geomagnetic storm
headed towards Earth has triggered a rare warning
from NOAA officials for the first time in two decades.
The warning comes following days of solar activity
that sent several waves of plasma in Earth's
direction along with powerful magnetic fields.
G4 storms are the second-strongest
type of geomagnetic storms and can
cause widespread voltage problems. .
NOAA warns that they can also cause some
protective assets to "trip out key assets from the grid,"
as well as cause orientation problems for spacecraft. .
If geomagnetic storms
were hurricanes, 'severe'
would be category 4. , Spaceweather.com, via CBS.
The powerful G4 storm could also cause
northern lights, or aurora borealis, to be seen
in northern California and as far south as Alabama.
In a May 9 press release, NOAA said that the solar
event began on May 8, when a group of sunspots
generated "several moderate to strong solar flares.".
According to NASA, solar flares are explosions of
radiation which are considered the strongest
explosive events in the solar system.
NOAA noted that the area, which
produced the recent flares, is roughly
16 times the diameter of the Earth.
The sunspots known as AR3664 measures about 124,000
miles across, and Space.com notes that it is one of the, "largest and most active
sunspots seen this solar cycle." .
According to NOAA, the geomagnetic storm
is expected to hit Earth as early as midday
on May 10 and continue through May 12
