James Webb Telescope captures amazing pictures of Uranus

Published

on

James Webb Space Telescope (JWST) has been capturing mesmerising images from space and it has yet again taken a jaw-dropping picture of Uranus showing its ring, luminous moons and atmosphere, said European Space Agency (ESA) in its explanation about the treasure trove.

Last year, a similar photo of Neptune was also captured by the JWST.

In the released image, 11 of the 13 rings can be seen with such brightness that they appear single, with the planet’s luminous atmosphere.

These rings have been earlier captured by only two times — first by Voyager 2 spacecraft in 1986, and second, by the advanced adaptive optics of the Keck Observatory, stated ESA.

The images from 1986 did not show it with such detailed features but the new picture shows how the technology has evolved that has preserved the sight of the inner features of Uranus.

Uranus is the 11th planet to the sun and is characterised by astronomers as an ice giant.

According to ESA, most of its mass is thought to be a hot, dense fluid of “icy” materials – water, methane and ammonia – above a small rocky core.

The image by JWST was combined with two filters — orange and blue.

The icy giant has a unique orbit around the sun and tilts around at a 90-degree angle. It causes the planet to experience extreme seasons, with each of its poles facing sunlight for many years and with the other side plunging into the dark for equally the same years and this changes as it tilts around the sun.

The current season at the northern pole of Uranus is Spring which can also be seen in the image with its right side brightening due to facing sunlight. It is for the first time since scientists have been able to see in such depth of Uranus.

On the left side of the icy giant in the image, clouds can be faintly seen. These clouds can only be seen at infrared wavelengths, according to ESA and “are theorised to be connected to storm activity across the ice giant”, members from the JWST team said.

At the beginning of 2028, Uranus would be experiencing Summer at its northern pole.

The amazing James Webb Telescope also captured 27 moons of Uranus that are too faint to be seen.

ESA stated: “Additional studies of Uranus are happening now, and more are planned in Webb’s first year of science operations.”

“Scientists expect that future Webb images of Uranus will reveal the two faint outer rings that were discovered with Hubble during the 2007 ring-plane crossing”, it added.

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
