NASA Issues Warning on Unprecedented X6.3 Solar Flare, Posing Threat to Communication Systems

NASA Issues Warning on Unprecedented X6.3 Solar Flare, Posing Threat to Communication Systems

(CTN News) – A stern warning has been issued by the National Aeronautics and Space Administration (NASA) in response to the intense solar flares that substantially threaten communication systems in space and on Earth.

On February 22, 2024, at 5:34 p.m. Eastern Standard Time (EST), the aerospace agency recorded a powerful flare that reached its peak and measured an astounding X6.3 on the solar activity scale.

27th Most Powerful Solar Flare in Recorded History

Solar flares, categorised into five categories ranging from A to X, with X-class flares being the most severe, can potentially interrupt various communication systems. This latest incident ranks as the 27th most powerful flare in the history of recorded flares, making it the largest flare that has been documented that has occurred since 2017.

In the days leading up to this very powerful X6.3 event, there were several significant flares, including an X1.8 on Wednesday and an X1.7 earlier on Thursday.

When the flare occurred, the National Oceanic and Atmospheric Administration (NOAA) of the United States warned that such phenomena could cause operators of high-frequency radios to experience a brief degradation of their signal or even a full loss of their signal. This was especially true on the side of the planet exposed to sunlight.

However, the National Oceanic and Atmospheric Administration (NOAA) emphasised the potential interruption to radar and GPS systems whilst assuring the public that these events did not constitute a serious threat to general safety.

Solar flares release dangerous radiation, threatening astronauts’ health and safety aboard the International Space Station (ISS) and the Tiangong space station in China. As a result, these astronauts are on high alert.

Seven International Space Station crew members and the three astronauts aboard Tiangong have been instructed to maintain vigilance as the solar activity continues.

However, even though the flares are occurring during Sun Cycle 25, which started in 2019 and is expected to peak around 2025, this most recent X6.3 flare is a noteworthy event during this cycle. It can potentially establish a precedent for additional activity in the future.

NASA Switches Off Instrument On Voyager 2 Spacecraft To Save Power

Voyager

NEW YORK — To save power, NASA turned off another scientific equipment on its long-running Voyager 2 spacecraft.

NASA Switches Off Instrument On the Spacecraft To Save Power

The space agency announced on Tuesday that 2’s plasma science instrument, meant to study the movement of charged atoms, was turned off in late September to allow the spacecraft to continue exploring for as long as possible, which is estimated to be into the 2030s.

NASA turned off a suite of instruments on Voyager 2 and its twin, Voyager 1, after exploring the gas giant planets in the 1980s. Both are currently in interstellar space or the region between stars. The plasma instrument on Voyager 1 stopped working years ago and was finally shut off in 2007.

The remaining four instruments on 2 will continue to collect data on magnetic fields and particles. Its mission is to investigate the regions of space beyond the sun’s protective sphere.

It launched in 1977, is the only spacecraft to have visited Uranus and Neptune. It is now more than 12 billion miles (19.31 billion kilometers) from Earth. 1 is more than 15 billion miles (24.14 billion kilometers) beyond Earth.

Hurricane Kirk Could Cause Dangerous Surf Conditions Along The US East Coast

kirk

MIAMI — Hurricane Kirk’s waves could generate life-threatening surf and rip current conditions this weekend throughout the United States East Coast, as well as in Bermuda, the Greater Antilles, and the Bahamas, according to forecasters.

Kirk was a Category 3 hurricane in the middle Atlantic Ocean that might grow further but was predicted to stay away from land, according to the Miami-based National Hurricane Center on Thursday.

Hurricane Kirk Could Cause Dangerous Surf Conditions Along The US East Coast

Kirk-generated swells were forecast to reach parts of the Leeward Islands on Friday, Bermuda and the Greater Antilles on Saturday, and the East Coast and the Bahamas on Sunday, according to the center.

No coastal watches or warnings were in effect. The major storm was around 1,130 miles (1,820 kilometers) east of the Leeward Islands, with maximum sustained winds of 125 mph (205 km/h).

Meanwhile, Tropical Storm Leslie formed late Wednesday in the eastern Atlantic and is expected to strengthen into a hurricane in the following days, forecasters said. It was also not considered a threat to the land.

The storm was about 540 miles (870 kilometers) southwest of Cabo Verde’s southernmost tip, with maximum sustained winds of 45 mph (75 kph), according to the center.

The storms raged in the Atlantic as rescuers in the United States Southeast sought for missing persons after Hurricane Helene struck last week, leaving a trail of death and devastation.

Giant Fossilised Footprint Of Dinosaur Found in China

Giant Fossilised Footprint Of Dinosaur Found in China

(CTN News) – A team of palaeontologists believes they have discovered fossilized footprints of one of China’s largest raptors. The collection of five fossilized dinosaur footprints is half the length of a school bus.

The footprints were discovered in a dinosaur trackway in south-east China in 2020. Scientists believe dinosaurs walked over the muddy river during the Cretaceous period, leaving footprints. Some footprints have been preserved for tens of millions of years.

The dinosaur trackway was unearthed in Longxiang and is around the size of a hockey rink. Some of the footprints are unusually formed, with intact imprints of only two toes.

Raptors, or predatory birds, are often small and referred to as deinonychosaurs. For example, a Velociraptor is around the size of a turkey. Few raptors, such as the Utahraptor and Dakotaraptor, increased in size significantly, reaching lengths of 5 to 6 metres. The Triassic ichthyosaur was the largest raptor known until now.

According to the scientists, the predator would have attacked its prey with a pair of huge “killing claws” on each foot.

What scientists discovered recently in China is massive, far larger than the largest superpredator known to date.

Scott Persons of the College of Charleston in South Carolina, and his colleagues, added another large raptor to the list. They named it Fujianipus, and they believe it lived in East Asia some 96 million years ago.

Persons and his colleagues are currently working on areas of Fujianipus’ skeleton, therefore little is known. The investigators only discovered a few of its 36-centimetre-long imprints.

“Preservation conditions were right for footprints but not so great for bones,” Persons said. However, scientists are certain that the footprints belong to a raptor because each one contains the imprint of only two toes, which corresponds to the foot anatomy of raptors. Raptors generally have three toes, but they keep one off the ground to preserve the big claw at the tip from wear and tear.

People believe Fujianipus demonstrates that raptors had the ability to grow much larger and compete with the largest predatory dinosaurs on the landscape at the time – allosauroids, some of which exceeded 10 metres or more in length.

According to Persons, raptors had an advantage over allosauroids in terms of speed. However, without fossilized leg bones, the researchers cannot correctly measure Fujianipus’ speed.
