Earth's magnetic poles not about to flip

The emergence of a mysterious area in the South Atlantic where the geomagnetic field strength is decreasing rapidly, has led to speculation that Earth is heading towards a magnetic polarity reversal. However, a new study that pieces together evidence stretching back 9,000 years, suggests that the current changes aren't unique, and that a reversal may not be in the cards after all.

Scientists at the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL) have refined the use of magnetic fields to improve the performance of doughnut-shaped fusion facilities known as tokamaks. The improved technique protects internal parts from damage by instabilities called "edge-localized modes" (ELMs) and allows tokamaks to operate for longer without pausing.
"O Difficult-to-observe effect confirms the existence of quark mass

A phenomenon that directly proves the existence of quark mass has been observed for the first time in extremely energetic collisions of lead nuclei. A team of physicists working on the ALICE detector at the Large Hadron Collider can boast this spectacular achievement - the observation of the dead cone effect.

A SpaceX cargo Dragon mission to the International Space Station will now launch no earlier than July 11, a delay of more than a month after engineers identified the source of elevated hydrazine readings in the spacecraft.
SpaceX closer to launching giant rocketship after FAA review
Tuesday, 14 June 2022 07:21 Write a comment
SpaceX cleared a key hurdle Monday for its plan to launch a gigantic, futuristic rocketship into orbit from Texas.
The Federal Aviation Administration concluded an environmental review of Elon Musk's Starship base. The agency saw no significant environmental concerns, but is requiring more than 75 actions to reduce impacts to the region.
It's no guarantee a launch license will be issued since other factors such as safety and financial responsibility requirements still must be met at the Boca Chica site, according to the FAA.
After the latest news, SpaceX tweeted: "One step closer to the first orbital flight test of Starship."
At nearly 400 feet (120 meters), Starship is the most powerful rocket ever built and meant to carry people to the moon and Mars. NASA intends to use it for the space agency's lunar landing of astronauts, planned no earlier than 2025.
While SpaceX has launched Starship's bullet-shaped upper stage several miles (10 kilometers) into the air over the past year—resulting in some spectacular explosions—it's yet to fly it atop a Super Heavy booster.
Some residents had opposed Starship launches and landings, citing not only the noise and closed roads, but also wreckage raining down from failed flights.

Astra rocket fails to deliver 2 small satellites after launch, NASA says
Monday, 13 June 2022 22:53 Write a comment
NASA said a rocket carrying two small weather satellites failed Sunday, preventing the inauguration of a technology that would have helped better forecast hurricanes.
The rocket by California-based Astra lifted off from Florida's Cape Canaveral Space Force Station, but the rocket's second stage malfunctioned before reaching orbit and lost the shoebox-sized technology.

On May 6, the International Journal of Astrobiology of Cambridge University Press published a paper titled 'An approximation to determine the source of the Wow! Signal', authored by Alberto Caballero, a Spanish astronomer and science communicator.
Caballero decided to search through a catalog of stars from the European Space Agency's Gaia satellite to look for possible candidates.

Since the first hot Jupiter was discovered in 1995, astronomers have been trying to figure out how the searing-hot exoplanets formed and arrived in their extreme orbits. Johns Hopkins University astronomers have found a way to determine the relative age of hot Jupiters using new measurements from the Gaia spacecraft, which is tracking more than a billion stars.

The subatomic particles called neutrinos, are believed to be ubiquitous throughout the Universe but are very difficult to detect. Now, Moroccan astrophysicist Salah Eddine Ennadifi and his co-workers, published a paper in EPJ Plus that describes the first known observation of intergalactic, high-energy neutrinos and probes new neutrino-related physics beyond the Standard Model of Particle Physic
