Parade of the Planets: A Fairytale Journey Through the Worlds of the Solar System

Image
 Episode 13 of Tales of Astronomy , titled Parade of the Planets , is a wonderful turning point in the series. Instead of focusing on just one planet, this episode looks back at the entire Solar System and brings together many of the scientific ideas introduced in earlier adventures. True to the spirit of the series, it does this not through a dry review lesson, but through a magical and imaginative story full of humor, worry, invention, and reflection. At the heart of the episode is a familiar pattern that Tales of Astronomy handles especially well: fear leads to curiosity, and curiosity leads to knowledge. This time, the fear comes from Pitia, who has heard that a “parade of the planets” is coming and immediately assumes it must mean bad luck and disaster. To calm her down, Yavor, Kristina, and Wendelin use a strange new invention — a machine that captures and displays memories. With its help, they revisit everything they have learned so far about the planets. This structure mak...

Facebook Admits Scanning Messenger Content Amid Data Misuse Scandal by Titan007

 In the wake of the massive unauthorized data use scandal, Facebook dropped another bombshell: it admits to reviewing messages people exchange on Messenger—text, photos, and links—claiming it’s to ensure users “play by the rules.”


The first hints came from Mark Zuckerberg, who said in an interview that Facebook played a role during last year’s crisis in Myanmar, where hate speech spread across the platform as more than half a million refugees fled to Bangladesh. According to him, Facebook detects such messages, including when people try to send sensational content via Messenger.
Other executives later confirmed that Messenger conversations are analyzed in much the same way Facebook reviews public posts, with the stated goal of preventing abuse.
“For example, in Messenger, when you send a photo, our system automatically scans it to check for child exploitation; when you send a link, it’s checked for malware. We designed these automated tools so we can stop inappropriate and violent behavior online at any moment,” the company says.
Many users believed these chats were completely private. Clearly, that’s not quite the case. Facebook insists the data viewed in this way isn’t sold to advertisers—but whether anyone believes that is another question.
Messenger used to be part of Facebook’s main app before it was split into a stand-alone app in 2014. Facebook’s other major chat app, WhatsApp, uses end-to-end encryption, meaning even WhatsApp can’t see message contents—making it feel safer to users and more challenging for investigators who want access. Messenger also offers an encrypted option, but users have to turn it on.
At the same time, the company confirmed it had shared personal data from 87 million users with Cambridge Analytica—far more than the previously assumed “only” 50 million. Initially, when the story first broke, Facebook claimed the privacy of roughly 270,000 users had been compromised.
