Scientists have long struggled to understand how common planets form. A new supercomputer simulation shows that the missing ingredient may be magnetism.

Egyptian stone predates the Sun

This Stone Predates the Sun.
Recent analysis of a stone found in the Libyan Desert Glass area of southwest Egypt, has sparked debate and a rethink of the current consensus on the formation of the solar system.
In a study, due to be published next month, a team of international researchers announced the resulting analysis of a stone that was subsequently named Hypatia after the ancient female astronomer of Alexandria.
Utilizing techniques from electron scanning microscopy, to proton induce X-ray emission and micro-Raman spectroscopy – the results revealed compounds not found anywhere on our planet, solar system or any known meteorite. As well, a lack of silicates was found which sets it apart from interplanetary dust particles and all known cometary material. Previous analysis of noble gas and nitrogen isotope studies suggest an extraterrestrial origin, which along with these new results strongly suggests a pre-solar origin and could indicate a high degree of heterogeneity in the solar nebula.
Researchers observed more than 500 of these mysterious cosmic explosions, unraveling the hidden nature of their sources.
The most popular theory suggests that FRBs come from neutron stars, the collapsed cores of massive stars. Scientists believe that the explosions could be a result of a specific type of neutron star known as a magnetar, named so for their powerful magnetic fields, thousands of trillions of times more powerful than Earth’s fields.
“The reason we think that’s true is because they are the only thing that we know of that could plausibly produce such energetic flashes in such a short duration of time,” Masui said. “Otherwise, we don’t really know how they’re created.”
On June 11, 2021 CNSA published new Hi-Res Mars images Zhurong Rover (Chinese Tianwen-1 mission) with amazing details of Utopia Planitia on Red Planet. Rover dropped/deployed special instrument camera to make group images. Camera made first shot capturing Mars Lander and Zhurong Rover together in single frame. Resolution of the images is incredible. Chinese Zhurong Mars Rover has been working on the surface of Mars for 26 Martian days, carrying out environmental perception, fire surface movement, and scientific exploration. Zhurong also made first panoramic 360 degrees image at Utopia Planitia on Mars. There is image of Parachute pack and Heat Shield on the surface of Red Planet.

The detection of energetic neutrino particles from outside the solar system has launched a new era of astronomy that could allow scientists to probe the mysteries of cosmic rays and other phenomena.
The photos include a 360 degree panorama of the terrain, a selfie of the rover, and a picture of the rover’s landing platform sporting a Chinese flag.
Colossal arc of distant galaxies makes astronomers question some of their most cherished principles about the cosmos.
He’s got a point. There’s a lot more space in the sky than on the ground, obviously, but flight paths need to be carefully planned and contained within specific areas, particularly in and near big cities. If flying taxis became affordable enough for people to use them the way we use Uber and Lyft today, there would quickly be all sorts of issues with traffic and congestion, both in the sky and with takeoff and landing space on the ground. So why not take a scaled approach from the beginning?
Speaking of affordability, Kelekona says that’s a priority, too. It may play out differently, especially in the technology’s early stages, but the intention is for tickets on the drone bus to cost the same as a train ticket for an equivalent distance. The first route, from Manhattan to the Hamptons, will reportedly have a 30-minute flight time and an $85 ticket price.
Other intended routes include Los Angeles to San Francisco, New York City to Washington DC, and London to Paris—all in an hour, which is comparable to the time it takes for a regular flight right now. One of the differences, ideally, will be that the eVTOLs will be able to land and take off closer to city centers, given that they won’t require long runways.
TAMPA, Fla. — Seraphim Capital plans to trade stakes it has amassed in space technology startups on the public market through an investment trust.
The Seraphim Space Investment Trust will eventually comprise bets in 19 international startups, including satellite data specialist Spire Global, quantum encryption firm Arqit and space-based cellular network operator AST Space Mobile.
Those three recently got valuations of more than $1 billion in mergers with special purpose acquisition companies (SPACs), investment vehicles that offer another route to public markets.
