Astronomers Discover Rare Reversed Black Hole For the First Time
Astronomers Discover Rare, Reversed Black Hole , For the First Time.
'The Independent' reports that NASA has
detected what they believe to be the spontaneous
reversal of a black hole's magnetic poles.
.
Rapid changes in visible and ultraviolet
light have been seen in a few dozen
galaxies similar to this one, Sibasish Laha, Research scientist at the University of Maryland, Baltimore County and Nasa’s Goddard Space Flight Center, via 'The Independent'.
But this event marks the first time we’ve
seen X-rays dropping out completely
while the other wavelengths brighten, Sibasish Laha, Research scientist at the University of Maryland, Baltimore County and Nasa’s Goddard Space Flight Center, via 'The Independent'.
Astronomers first noticed that
a galaxy called 1ES1927+654 had brightened
by nearly 100 times in March 2018.

.
According to further research,
the eruption had begun at the end of 2017.
'The Independent' reports that
a supermassive black hole resides
at the center of most large galaxies.
According to astronomers, the magnetic field of the black
hole is what creates and sustains the corona, a cloud of
extremely hot particles that produce high-energy x-rays.
A magnetic reversal, where the north pole
becomes south and vice versa, seems to best
fit the observations.
The field initially
weakens at the outskirts of the accretion
disk, leading to greater heating and
brightening in visible and UV light, Mitchell Begelman, Co-author and professor in the department of astrophysical and planetary sciences at the
University of Colorado Boulder, via 'The Independent'.
The team's findings have been accepted for publication in 'The Astrophysical Journal.'
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.

Last week, workers held sit-in
protests at Google's offices in both
New York and Sunnyvale, California.
The protests were organized by the group
No Tech For Apartheid, who said that 30 workers
were fired following the initial sit-in. .
According to Jane Chung, a spokeswoman for
No Tech For Apartheid, Google has now fired
"over 20" more workers, “including non-participating
bystanders during last week’s protests.”.
Google’s aims are clear:
the corporation is attempting
to quash dissent, silence
its workers, and reassert
its power over them, Jane Chung, a spokeswoman for No Tech For Apartheid, via 'The Independent'.
In its attempts to do so,
Google has decided to
unceremoniously, and
without due process,
upend the livelihoods of
over 50 of its own workers, Jane Chung, a spokeswoman for No Tech For Apartheid, via 'The Independent'.

Google has disputed the group's claims,
stressing that the company carefully found that, “every single one of those whose employment
was terminated was personally and definitively
involved in disruptive activity inside our buildings.”

Upcoming , Lyrid Meteor Shower , May Be Hard to See.
'The Independent' reports that skywatchers
looking to catch the Lyrid meteor shower
may be foiled by the moon. .
This year's peak activity occurs
on April 21 and 22, with up to
20 meteors expected per hour. .
Potential viewing should
last through April 29. .
However, the American Meteor Society
warns that strong moonlight
may interfere with viewing. .
Every year, multiple meteor showers
occur and don't require special
equipment to see them. .
For the most part, meteor showers originate
from debris left behind by comets, like the Lyrids,
which come from the comet Thatcher. .
As these space rocks enter the Earth's atmosphere,
air resistance makes them extremely hot,
which causes the air around them to glow.
This glow leaves a fiery trail behind
the meteor, which can be observed
from the ground as a "shooting star.".
Look to the northeast and just
keep staring at the same spot
in the sky. It's always impressive
when you see these things, Don Pollacco, University of Warwick
astronomer, via 'The Independent'.
The Lyrids are best viewed from the Northern Hemisphere,
while the upcoming Eta Aquarids meteor shower
can best be seen from the Southern Hemisphere.

EPA Takes Aim at, US Chemical Emissions, That Are Likely Carcinogens.
'The Independent' reports that over 200 chemical
plants in the United States will be required
to reduce toxic emissions under a new rule. .
The Environmental Protection Agency (EPA)
released the new rule regarding toxic
emissions likely to cause cancer on April 9.
The rule is meant to deliver critical health protections
for communities faced with industrial pollution from
dangerous chemicals, such as chloroprene and ethyl oxide.
The rule will significantly reduce
emissions from the Denka Performance
Elastomer facility in LaPlace, Louisiana.
The facility is the largest producer of
chloroprene emissions in the U.S., according
to EPA Administrator Michael Regan.
Every community in this country
deserves to breathe clean air.
That’s why I took the Journey
to Justice tour to communities
like St. John the Baptist Parish,
where residents have borne
the brunt of toxic air for far too long, Michael Regan, EPA Administrator, via 'The Independent'.
We promised to listen to folks that
are suffering from pollution and act
to protect them. Today we deliver
on that promise with strong final
standards to slash pollution,
reduce cancer risk and ensure
cleaner air for nearby communities, Michael Regan, EPA Administrator, via 'The Independent'.
According to officials, the changes
are meant to reduce ethylene oxide and
chloroprene emissions in the U.S. by nearly 80%.
'The Independent' reports that the rule updates
several regulations on chemical plant emissions
that have not been altered in nearly 20 years.
The EPA said that the new rule will reduce a total of over
6,200 tons of toxic air pollutants annually in an effort
to address health risks in neighboring communities

Scientists Capture , Radio Signals , From Long-Dormant Star.
'The Independent' reports that scientists have
been puzzled after receiving unprecedented
radio signals from a previously dormant star.
The star, named XTE J1810-197, is a magnetar. .
Magnetars are a type of neutron star and are
the most powerful magnets in the universe.
XTE J1810-197 is the nearest known magnetar
to Earth, about 8,000 light years away.
Now, scientists have received radio
pulses from the dormant star that
do not fit previous expectations.
Unlike the radio signals we’ve
seen from other magnetars,
this one is emitting enormous
amounts of rapidly changing
circular polarisation. We had never
seen anything like this before, Marcus Lower, Postdoctoral fellow
at Australia’s national science agency,
CSIRO, via 'The Independent'.
Scientists discovered that the new pulses are emitting
a type of spiraling light that is different from the
polarized light emitted by most other magnetars.
In 2003, XTE J1810-197 became
the first known magnetar to
produce a radio signal.
After being discovered, the magnetar
then went silent for over a decade. .
The team that discovered it said that
the findings could change our
understanding of intense magnetic fields.
The signals emitted from
this magnetar imply that
interactions at the surface
of the star are more complex than
previous theoretical explanations, Manisha Caleb, University of Sydney,
a co-author on the study, via 'The Independent'.
The team's findings were published
in the journal 'Nature Astronomy.'

Here's How
Daylight Saving Time , Affects Your Health.
Daylight Saving Time starts at
2 A.M. on March 10th.
This means we lose
a full hour of sleep.
A study from the
University of Colorado says
that when clocks are moved up.
the effect has a
negative impact
on one's health.
According to the study,
heart attack risk increases by
25% due to the loss of sleep.
The risk drops 21%
in the fall when we
gain an hour of sleep.
The Mayo Clinic adds that daylight savings affects sleeping patterns
for nearly a week.
To help remedy, the
Better Sleep Council has a tip.
The nonprofit says to go to sleep
15 minutes before your normal bedtime days before the shift
