Jupiter now has ‘most moons’ in solar system

Published

on

In addition to being the biggest and most massive planet in the solar system, Jupiter now has the most moons around it, at 92, making the gas giant the largest body in the solar system overall.

According to a recent article from Sky and Telescope, the Minor Planet Centre (MPC), run by the Smithsonian Astrophysical Observatory, has revealed the orbits of the 12 unidentified moons of Jupiter. With these recent discoveries, Jupiter has surpassed Saturn to claim the title of “planet in the solar system with the most moons.”

Around the ringed gas giant, the second-largest planet in the solar system, researchers have discovered 83 moons so far. But according to Sky and Telescope, astronomers have also discovered tonnes of rocks up to around 2 miles (3 kilometres) wide near Saturn without yet properly tracking the objects. Jupiter may have to give back its new title to Saturn as soon as technology allows for the study of these smaller moons.

The observations of the Jovian system, made in 2021 and 2022, have been submitted for publication by Scott Sheppard, an astronomer at the Carnegie Institute for Science in Washington, DC, reported Space. The reason for the gap between the discovery of the new moons and their confirmation is that astronomers had to follow the pebbles for a full orbit to make sure they were indeed orbiting Jupiter.

According to Sky and Telescope, all of the new moons orbit Jupiter at a distance from its surface, taking more than 340 Earth days to do so. Nine of the 12 new moons are extremely far away. Their orbits are longer than 550 days. All of these moons are small; just five of those nine moons are believed to have a diameter larger than five miles (8 km).

The outer Jovian moons, in contrast, have “prograde” orbits that circle the gas giant in the same direction as the planet’s spin. The nine moons that are very far away have retrograde orbits, which means that they circle the gas giant in the opposite direction from its rotation. The retrograde orbits of the new moons suggest that Jupiter’s powerful gravitational pull may have grabbed these moons, with the smaller ones perhaps being the fragments of larger entities that collided and broke apart.

The prograde orbits of some of the recently discovered moons indicate that they developed around Jupiter. Io, Europa, Ganymede, and Callisto are the large inner moons that are known as the Galilean moons because they were first discovered by Galileo Galilei in the early 1600s. These prograde orbiting moons are situated in a middle swath of space with 13 other Jovian moons.

Cybersecurity firm reports exposure of sensitive DeepSeek data on the internet.

The New York-based cybersecurity firm Wiz has discovered a cache of sensitive data from the Chinese artificial intelligence business DeepSeek that was mistakenly exposed to the public internet.

In a blog post released on Wednesday, Wiz reported that examinations of DeepSeek’s infrastructure revealed that the company had inadvertently exposed over a million lines of unencrypted data. The materials were digital software keys and chat logs that seemingly documented prompts transmitted from consumers to the company’s complimentary AI assistant.

The chief technical officer of Wiz stated that DeepSeek promptly safeguarded the data following the notice from his organisation.

“It was removed in under an hour,” stated Ami Luttwak. “However, this was exceedingly easy to locate, leading us to believe we are not the sole discoverers.”

DeepSeek did not promptly respond to a request for comment.

DeepSeek’s rapid success after the introduction of its AI helper has exhilarated China and incited concern in America. The Chinese company’s evident capacity to rival OpenAI’s skills at a significantly reduced cost has raised concerns regarding the viability of the business models and profit margins of U.S. AI behemoths like Nvidia and Microsoft.

By Monday, it surpassed the U.S. competitor ChatGPT in downloads from Apple’s App Store, prompting a worldwide decline in technology stocks.

WhatsApp launches bulk channel management functionality

Published

By

WhatsApp has initiated testing of a bulk channel administration feature on iOS for select beta users, enabling the simultaneous selection of many channels, hence enhancing the efficiency of managing following channels.

This essential update enables users to perform bulk activities, including muting many channels simultaneously, designating them as read, and altering notifications. If the chosen channels are muted, users will now have the option to activate notifications. Users can swiftly silence unmuted channels in one action.

Additionally, this feature enables users to unfollow many channels simultaneously, thereby optimizing the process of decluttering their channel list. This change is particularly beneficial for users that oversee numerous subscriptions, as reported by WABetaInfo.

Previously, users were required to manage each channel individually, rendering tasks such as muting or designating channels as read laborious and time-consuming.

The functionality provides enhanced flexibility and control over channel subscriptions, enabling users to efficiently manage notifications. The solution streamlines laborious operations for consumers who subscribe to numerous channels, hence enhancing their entire experience.

Accessibility
The bulk management feature is presently accessible exclusively to a limited number of beta testers who installed the latest WhatsApp beta for iOS using the TestFlight application. WhatsApp, owned by Meta, plans to expand the feature’s availability to a larger user base in the next weeks.

This update demonstrates WhatsApp’s dedication to enhancing user experience by offering a clear and efficient method for managing channels and notifications.

Even after two weeks, the global submarine cable AAA-1 problem that was discovered on January 2 near Qatar has not been fixed, causing sluggish internet connection in several Pakistani towns.

According to a representative for Pakistan Telecommunication Company Limited (PTCL), the issue has affected customers’ capacity to effectively access social media applications and browse the online. Even with initiatives to fix the problem, social networking sites still lag during busy times.

Internet traffic has been redirected via alternate channels to lessen the impact, and more capacity has been set up to stabilize the service.

The PTCL representative promised that “Internet service across the country is operating normally, and there will be no issues with web browsing,” noting that social media applications’ lag is common during
