Dead satellites are filling space with trash. That could affect Earth’s magnetic field

Space trashA dead spacecraft the size of a truck ignites with plasma and pulverizes into dust and litter as it rips through the ionosphere and atmosphere. This is what happens to internet service satellites during re-entry. When the full mega-constellation of satellites is deployed in the 2030s, companies will do this every hour because satellite internet requires thousands of satellites to constantly be replaced. And it could compromise our atmosphere or even our magnetosphere.

Space entrepreneurs are betting on disposable satellites as key to a new means of wealth. There are currently nearly 10,000 active satellites and companies are working as fast as possible to get tens of thousands more into orbit – for a projected 1m in the next three to four decades.

“We could get to 100,000 satellites in 10 to 15 years,” Dr Jonathan McDowell, of the Harvard-Smithsonian Center for Astrophysics, told me. Those satellites power hyper-connected internet services and may turn some billionaires into trillionaires – at the cost of shrouding the planet with toxic trash.

Peter Higgs, who proposed the existence of the so-called 'God particle,' has died

Peter Higgs dies at 94Nobel prize-winning physicist Peter Higgs, who proposed the existence of the so-called "God particle" that helped explain how matter formed after the Big Bang, has died at age 94, the University of Edinburgh said Tuesday.

The university, where Higgs was emeritus professor, said he died Monday "peacefully at home following a short illness."

Higgs predicted the existence of a new particle — the so-called Higgs boson — in 1964. But it would be almost 50 years before the particle's existence could be confirmed at the Large Hadron Collider.

Higgs' theory related to how subatomic particles that are the building blocks of matter get their mass. This theoretical understanding is a central part of the so-called Standard Model, which describes the physics of how the world is constructed.

Images from the Solar Eclipse: See photos of the rare event on April 8, 2024

Eclipse photos

A total solar eclipse dazzled citizens of the United States, Mexico and Canada on Monday, giving those lucky enough to have experienced clear skies with a somewhat rare celestial show.

People in Mazatlán, Mexico were the first to see the total solar eclipse at 2:07 p.m. ET. It then continued into Texas and along a “path of totality” spanning more than 100 miles across the width of the continent.

In the U.S., the sun was fully obscured by the moon for a few minutes in 15 states from Texas to Maine, but the eclipse was at least partially visible in 49 states. Alaska was the only state where the eclipse wasn't visible.

Follow along below for Yahoo News’s live coverage of Monday’s total solar eclipse. For those unable to view the eclipse in person, you can watch it in real time by clicking here.

What time is the total solar eclipse on April 8? Search your ZIP code for a viewing guide

Total eclipse April 8th

Get ready for a spectacular show: A total solar eclipse will occur above the U.S. on the afternoon of April 8.

Most Americans will be able to see it in some form, but the distance between your location and the path of totality will determine how much of the sun will be covered by the moon. Many places in the U.S. − Rochester, N.Y., Cleveland, and Austin, Texas, to name a few − will see a total eclipse, in which the sun is completely obscured. Other locations will see a partial eclipse. Search for your ZIP code below or select a major city to reveal the time, duration, peak and percentage of the eclipse in your area.

On April 8 the moon will travel along the path of totality in North America starting in northern Mexico. The shadow of the moon will pass into Texas a little before 1:30 p.m. local time. It will then cover portions of the Midwest and East Coast and touch southeast Canada before it moves out to sea, according to NASA.

NASA Concerned as Voyager 1 Sending Back Incomprehensible Code

Voyager I

NASA's two Voyager spacecraft have spent almost half a century traveling through distant space.

The probes, which launched less than a month apart in the summer of 1977, have survived a lot, from dwindling power supplies and grimy thrusters to near-fatal software glitches.

Voyager 1, in particular, which is currently floating past the generally-defined edge of the solar system some 15 billion miles away, is looking worse for wear these days.

Most recently, scientists became worried after the lonely probe started sending nonsensical messages back to Earth — as if its senility was catching up with it.

No Daddy Shark in sight: Zoo greets a cute shark pup after apparent parthenogenesis

by shark worn without a daddy

What if the song "Baby Shark" stopped after just two stanzas?

For non-fans of the catchy tune, that might sound like a dream. For a real-life Mommy Shark in Illinois, it's reality: She produced a baby without a Daddy Shark.

The epaulette shark pup hatched this summer at Brookfield Zoo, just west of Chicago. Its mother has been at the zoo since 2019; in that time, she's never shared a tank with a male.

It's a rare case of parthenogenesis, a type of asexual reproduction, according to the zoo.

Joro spiders, huge and invasive, spreading around eastern US, study finds

Joro spiders here to stay

The latest species of spider found in the U.S. are huge, brightly colored and travel in a method described as "ballooning." And, according to new research, they're spreading out to new states around the country.

Researchers at Clemson University published a study on Joro spiders, coming to the conclusion that the species is spreading rapidly beyond the South Carolina area, and data shows they could inhabit most of the eastern U.S.
