black holes are awesome and powerful and can seem a bit scary thanks to their reputation for gravitational pulls so strong not even light can escape. So let’s give a big welcome to Gaia BH1, the new closest black hole to Earth.

Gaia BH1 is dormant, 10 times more massive than our sun and located about 1,600 light-years away in the constellation Ophiuchus (the serpent-bearer). The team behind the discovery says it’s three times closer to Earth than the previous winner, a black hole located in the Monoceros (unicorn) constellation. Gaia BH1 is close enough that the National Science Foundation’s NOIRLab astronomy center considers it to be “in our cosmic backyard.”

“While there have been many claimed detections of systems like this, almost all these discoveries have subsequently been refuted,” said astrophysicist Kareem El Badry in a NOIRLab statement Friday. “This is the first unambiguous detection of a sun-like star in a wide orbit around a stellar-mass black hole in our galaxy.” Stellar-mass black holes are within five to 100 times the mass of our sun, as compared with supermassive black holes that live in the centers of galaxies.

El-Badry is the lead author of a paper on the black hole published in the Monthly Notices of the Royal Astronomical Society journal this week. The lengthy co-author list points to how complex and challenging the study was. Finding this black hole was a science triumph with many layers.

The story starts with the European Space Agency’s Gaia space observatory, which

How weak leadership cratered Twitter’s morale

The billionaire Tesla CEO has changed his Twitter bio to Chief Twit. On Thursday his biographer Walter Isaacson posted a picture of Musk hobnobbing with Twitter employees at its San Francisco headquarters. He brought in Tesla engineers to “assess” the company’s code. And in a conciliatory post, Musk promised advertisers that under his watch Twitter would not be “a free-for-all hellscape, where anything can be said with no consequences.”

“Advertising, when done right, can delight, entertain, and inform you,” he wrote — an acknowledgment, perhaps, that ads accounted for 89 percent of Twitter’s revenue last year.

The purgatory the company now finds itself in long predates Musk’s involvement

After formally taking control Thursday night, Musk quickly dismissed several of Twitter’s top executives, including CEO Parag Agrawal, CFO Ned Segal, and policy leader Vijaya Gadde, according to multiple reports.

Whatever Twitter may be about to go through, the purgatory the company now finds itself in long predates Musk’s involvement. Under former CEO Jack Dorsey, the company struggled to build a profitable business, despite operating a service with outsized cultural influence and one of the world’s most elite user bases. And Twitter’s weak leadership had proven to be a drag on company morale.

Documents shared with Platformersas well as interviews with current and former employees, illustrating how Dorsey’s waning attention to the platform, coupled with dissatisfaction with the company’s response to the COVID-19 pandemic, trust and safety issues, and other challenges, had left a significant percentage of

Tablets are popular because they can be used for everything from school and home office tasks to entertainment and content creation. Finding a good tablet isn’t hard, but knowing where to start can be overwhelming if you’re trying to find the right combination of features and affordability.

Let’s start with Apple, which updated its entire iPad lineup in 2022. Along with faster processors across all of the latest models, Apple introduced the 10th-gen iPad with an entirely new design. However, the updated look and features come at a higher price, so Apple is still selling the ninth-gen iPad as its least expensive option.

Elsewhere in Best Tablet Land, Microsoft debuted a new Surface Pro 9 models in the fall of 2022. Meanwhile, Android tablets are available in a wide range of sizes and prices from the value-packed Amazon Fire tablets to Samsung’s top Galaxy Tab models that are strong competition for Apple’s iPad Pro.

In the value segment, Amazon’s Fire tablets remain the best tablet option for cheap and kid-friendly models. But if you’re looking for something that’s good for productivity and entertainment, there’s an affordable Chromebook that blurs the line between laptop and tablet.

If you’re definitely going with an iPad, though, we strongly recommend you check out the entire iPad lineup because there

Chinese Rocket Plummets to Earth, Causing One Country to Halt Air Traffic

A Chinese rocket booster made an out-of-control reentry into Earth’s atmosphere over the water early Friday, the US military’s Space Command confirmed.

The booster is the first stage of a Long March 5B rocket that several days ago sent a large module to orbit to expand China’s Tiangong space station.

“The People’s Republic of China Long March 5B #CZ5B rocket reentered the atmosphere over the south-central Pacific Ocean at 4:01 am MDT/10:01 UTC on 11/4,” the US Space Command tweeted Friday.

#USSPACECOM can confirm the People’s Republic of China Long March 5B #CZ5B rocket re-entered the atmosphere over the south-central Pacific Ocean at 4:01am MDT/10:01 UTC on 11/4. For details on the uncontrolled reentry’s impact location, we once again refer you to the #PRC.

The Long March 5B weighs over 20 metric tons, measures 10 stories tall and appears to lack the hardware to make a controlled reentry and steer itself toward a safe, planned splashdown.

Instead, the Chinese space program rolled the dice that what remained of the rocket, after much of it burned up in the atmosphere, would land somewhere on the majority of the planet’s surface that is either unpopulated or covered by ocean.

It seems the gamble worked out this time, but in the process the dramatic descent caused a 40-minute closure of a significant portion of Spanish airspace, causing delays to around 300 flights, according to the Reuters news agency. It also potentially littered debris over
