Nach den frühen Black Friday Angeboten geht bei Amazon jetzt endlich die Black Friday Woche mit zahllosen Bestpreisen in allen Kategorien los. (Black Friday, Amazon)

Since early July, telescopes around the world have been tracking just our third confirmed interstellar visitor, the comet 3I/ATLAS—3I, for third interstellar, and ATLAS (Asteroid Terrestrial-impact Last Alert System) for the telescope network that first spotted it. But the object’s closest approach to the Sun came in late October during the US government shutdown. So, while enough people went to work to ensure that the hardware continued to do its job, nobody was available at NASA to make the images available to the public or discuss their implications.

So today, NASA held a press conference to discuss everything that we now know about 3I/ATLAS, and how NASA’s hardware contributed to that knowledge. And to say one more time that the object is a fairly typical comet and not some spaceship doing its best to appear like one.

Extrasolar comet

3I/ATLAS is an extrasolar comet and the third visitor from another star that we’ve detected. We know the comet part because it looks like one, forming a coma of gas and dust, as well as a tail, as the Sun heats up its materials. That hasn’t stopped the usual suspect (Avi Loeb) from speculating that it might be a spacecraft, as he had for the earlier visitors. NASA doesn’t want to hear it. “This object is a comet,” said Associate Administrator Amit Kshatrya. “It looks and behaves like a comet, and all evidence points to it being a comet.”

When a Cloudflare outage disrupted large numbers of websites and online services yesterday, the company initially thought it was hit by a “hyper-scale” DDoS (distributed denial-of-service) attack.

“I worry this is the big botnet flexing,” Cloudflare co-founder and CEO Matthew Prince wrote in an internal chat room yesterday, while he and others discussed whether Cloudflare was being hit by attacks from the prolific Aisuru botnet. But upon further investigation, Cloudflare staff realized the problem had an internal cause: an important file had unexpectedly doubled in size and propagated across the network.

This caused trouble for software that needs to read the file to maintain the Cloudflare bot management system that uses a machine learning model to protect against security threats. Cloudflare’s core CDN, security services, and several other services were affected.

It took the California Science Center more than three years to erect its new Samuel Oschin Air and Space Center, including stacking NASA’s space shuttle Endeavour for its launch pad-like display.

Now the big work begins.

“That’s completing the artifact installation and then installing the exhibits,” said Jeffrey Rudolph, president and CEO of the California Science Center in Los Angeles, in an interview. “Most of the exhibits are in fabrication in shops around the country and audio-visual production is underway. We’re full-on focused on exhibits now.”

Nobody expects to get sued for re-posting a YouTube video on social media by using the “share” button, but librarian Ian Linkletter spent the past five years embroiled in a copyright fight after doing just that.

Now that a settlement has been reached, Linkletter told Ars why he thinks his 2020 tweets sharing public YouTube videos put a target on his back.

Linkletter’s legal nightmare started in 2020 after an education technology company, Proctorio, began monitoring student backlash on Reddit over its AI tool used to remotely scan rooms, identify students, and prevent cheating on exams. On Reddit, students echoed serious concerns raised by researchers, warning of privacy issues, racist and sexist biases, and barriers to students with disabilities.
