Potential sat-bothering cannibal coronal mass ejection slams into Earth's atmo tonight
A so-called cannibal coronal mass ejection is set to hit Earth on December 1, creating geomagnetic storms across the skies at higher latitudes.
When the Sun's magnetic field lines twist and realign, the star ends up shedding gigantic clouds of charged particles from its surface.
These coronal mass ejections (CMEs) weigh billions of tons, and barrel through space at speeds ranging from 12 to 1,250 miles per second (about 20 to 2,000 kilometres per second). If multiple CMEs are expelled in succession, faster bursts can overtake and assimilate slower ones in front to create what scientists call cannibal CMEs.
The Sun has been particularly active as of late, spewing three solar flares in one go on November 27 and a fourth a day later. That fourth burst is expected to spread and merge with two of the three slower flares to form a large cannibal CME, scheduled to hit Earth on in the early hours of December 1 (UTC).
When the burst reaches Earth, showers of charged particles will hit the atmosphere. The impact will release energy in the form of light, creating auroras that could be visible to the naked eye if the sky is clear and dark enough.
Meteorologists at AccuWeather reckon viewers in the northern half of the US may get to catch a glimpse of the geomagnetic storm's fallout. Auroras are expected from Washington to New York, and may even reach as far south as Pennsylvania, Missouri, Colorado, and Northern California.
"The best viewing conditions are predicted across the Canadian Prairies and into Ontario, Minnesota, northern Wisconsin and the Upper Peninsula of Michigan," explained Brian Lada, a meteorologist at AccuWeather.
Meanwhile, folks across the pond in the UK might not get to see the Northern Lights. The bulk of the geomagnetic storm will hit during the day when it's too bright to see, according to the Met Office.
But there is a small chance it might be visible in northern Scotland during the evening. If the event is strong and lingers for long enough, however, it may be possible to view for those in northern England and Northern Ireland.
For readers in the Southern hemisphere, the Australian Bureau of Meteorology's Space Weather Forecasting Centre predicts that the Southern Lights could be visible as far north as Victoria and other southern parts of the country.

The animal astronauts of Iran
Iran has sent a capsule carrying animals into space as it boosts its Western-contested space programme in preparation for human missions.
State media on Wednesday released a clip of the launch of an Iranian-made rocket carrying the capsule, which they said was successfully sent 130km (80 miles) into orbit.
The Salman rocket carried an “all indigenous” capsule weighing 500kg (1,100 pounds), which is reportedly the heaviest biological capsule ever successfully carried in the history of the Iranian space programme.
Neither state media nor Telecommunications Minister Isa Zarepour, who confirmed the news, said what kind of animals were in the capsule.
Iran started work on sending animals into space in the mid-2000s and had its first successful launch in 2010. It reported in 2013 that it had sent two monkeys into space and brought them back.
Dalirian claimed on Wednesday that the administration of President Ebrahim Raisi has “effectively revived” work on Iran’s longer-term goal of sending humans into space.

NASA streamed its 1st video from deep space via laser. More important, it's of a cat
Taters the cat chasing a laser pointer actually marked a historic scientific milestone
It's not every day that a video of a cat goes viral.OK, it's not every day that a video of a cat goes viral and marks a historical milestone for space exploration. But that's what happened when NASA's Deep Space Optical Communications experiment beamed an ultra-high definition streaming video back to Earth on Dec. 11 from 31 million kilometers away, or about 80 times the Earth-Moon distance.
The 15-second test video is part of a NASA technology demonstration aimed at streaming very high-bandwidth video and other data from deep space — enabling future human missions beyond Earth's orbit, according to the space agency's press release.
But more importantly, perhaps to some, is the subject of the video: a cat named Taters chasing a laser pointer on a couch. That's it. That's the whole video.
"Everyone loves Taters," explained Bill Klipstein, the tech demo's project manager at NASA's Jet Propulsion Laboratory (JPL). He further explained that they wanted a fun video "to make this significant event more memorable."
The video of Taters, who belongs to one of the employees at the JPL, was uploaded before the launch. The video signal took 101 seconds to reach Earth, sent at the system's maximum bit rate of 267 megabits per second (Mbps).

Cats in space
Somehow, this isn't even the first time a cat video has been used to mark a technology transmission. Starting in 1928, a small statue of the cartoon character Felix the Cat was used to test early television broadcast transmissions. According to Poynter, the image was broadcast for two hours day, "simply turning on a turntable." (Would watch.)Taters also isn't the first cat to make space-travel history. In 1963, a cat named Félicette (named after Felix the Cat, the very same cartoon character) had the honour in real life when France decided to send a feline into orbit.
Félicette spent about five minutes in space and survived, only to be euthanized two months later so scientists could examine how space flight affected her body, according to BBC.
In 2019, after a Kickstarter campaign was launched to honour the cat's contributions, a bronze statue of Félicette was unveiled at the International Space University in Strasbourg, France.
One can hope for a happier outcome, but similar accolades, for Taters.

Neptune and Uranus seen in true colours for first time
Our ideas of the colours of the planets Neptune and Uranus have been wrong, research led by UK astronomers reveals.
Images from a space mission in the 1980s showed Neptune to be a rich blue and Uranus green.
But a study has discovered that the two ice giant planets are both similar shades of greenish blue.
It has emerged that the earlier images of Neptune had been enhanced to show details of the planet's atmosphere, which altered its true colour.
"They did something that I think everyone on Instagram will have done at some time in their life, they tweaked the colours," Prof Catherine Heymans, Astronomer Royal for Scotland and a University of Edinburgh astrophysics professor, told BBC Radio 4's Today.
"They accentuated the blue just to reveal the features that you can see in Neptune's atmosphere, and that's why the image looks very blue, but in reality, Neptune is actually pretty similar to Uranus."
Astronomers have long known that most modern images of the two planets do not accurately reflect their true colours, according to Prof Patrick Irwin from the University of Oxford, who led the research.
"Even though the artificially saturated colour was known at the time amongst planetary scientists - and the images were released with captions explaining it - that distinction had become lost over time."
Dr Robert Massey, deputy director of the Royal Astronomical Society (RAS), explained that enhancing images was normal procedure in astronomical research.
"You would be foolish to look at an astronomy image and not think it was enhanced. They have to be, because that is how they are processed in order to see things.
"It's not that there was any conspiracy to keep it from the public!"
Prof Irwin and his team processed the original data to produce what is claimed to be ''the most accurate representation yet'' of the colour of both Neptune and Uranus.
The initial misconception arose because images captured of both planets by Nasa's Voyager 2 spacecraft mission recorded its images in three separate colours.
True colours
The images were recombined to create the composite colour images, which were not always accurately balanced. The contrast was also strongly enhanced to bring out details in the clouds, bands and winds of the planets. In the case of Neptune, both processes made it bluer than it really was.In the recent study, the researchers used data from the Hubble Space Telescope Imaging Spectrograph and the Multi Unit Spectroscopic Explorer on the European Southern Observatory's Very Large Telescope.
In both instruments, each pixel is a continuous spectrum of colours which enables the researchers to produce the true colours of both planets.
The analysis revealed that Uranus and Neptune are a similar shade of greenish blue, although researchers found a slight difference. Neptune has a slight hint of additional blue, which the model reveals to be because of a thinner haze layer on that planet.
The study also showed that Uranus appears a little greener during its summer and winter, when one of its poles is pointed towards the Sun. But during spring and autumn, when the Sun is over the equator, it has a bluer tinge.

That is so lucky. I do not know what it is like in internal US flights like that, but there are not many spare seats on most flights I take.
I know right. Lucky!

In Europe cockpit voice recorders are required to store 25 hours of data before the audio is rewritten. I think we should do the same in the US, or at least raise the limit to 8 hours to cover the entirety of a coast-to-coast flight with some time to spare.

I suspect they were compliant with the relevant international standard for cockpit recording.
And a problem with international standards is getting the standards updated.
That is one of the reasons I am generally sceptical about treaty imposed standards.

Please expand the abbreviation FAA.
I meant the Federal Aviation Administration, but I do not know who makes these particular rules. I am fairly sure whoever it is answers to the POTUS and no one else.

JAXA's SLIM space probe made it successfully to the Moon, but its solar panels aren't working, so it may not be able to conduct the science that researchers wanted it to. The goal was to use the spectrometer to determine the composition of the Mare Nectaris section of the Moon.
