Halley's Comet Is About to Return From the Outer Solar System
Halley's Comet Is, About to Return From , the Outer Solar System.
After nearly 40 years, Halley's comet will once
again reach its furthest point from the Sun
and begin its return journey back toward Earth.
.
'The Byte' reports that the comet will reach its "aphelion"
on December 9, which represents the middle point of
Halley's elliptical orbit through the solar system.
The comet was named for 18th century
English astronomer Edmond Halley.
After hitting its aphelion near Jupiter,
its long journey through space will next
bring the comet past Earth in the year 2061.
'The Byte' reports that the debris from the tail
of Halley's comet is still visible from Earth
in the form of the Eta Aquariids meteor shower.
.
Between late April and early May, Earth passes through
remnants of the comet, with those in the Northern
hemisphere able to see 10 to 20 meteors per hour.
.
Before the end of 2023, Earth will also see the peak of
the Geminids meteor shower on December 13 and 14.
.
NASA meteor expert Bill Cooke told Space.com
that this year's viewing conditions for the
meteor display are supposed to be exceptional.
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

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.

Earth has been rocked by the first extreme geomagnetic storm in two decades, creating a spectacular light show in UK skies and other parts of the Northern.. Sky News
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.

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.

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."

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
