NASA to launch Roman telescope capable of capturing extensive space data

Published

on

The amazing James Webb Space Telescope has allowed astronomers to unravel the mysteries of the cosmos as it shared a number of mesmerising pictures of the galaxies. 

But scientists from NASA are putting their effort to build another space telescope, bigger than the James Webb. “Nancy Grace Roman Space Telescope” is scheduled to be launched by 2027, Euronews Next reported.

Dubbing it “a new age for astronomy”, one of the scientists working on the telescope project said the telescope would allow acquiring more information and would help answer further riddles about astrophysics.

The telescope would provide a more “panoramic view of the universe and allow more statistical studies,” said Marco Sirianni, ESA’s Science Operations Development Manager, working on the project.

Difference between Roman Telescope, James Webb and Hubble?

As the pictures released last year by James Webb and Hubble, they provide detailed insights and views on small parts of space whereas, Roman, it is said, would give a much broad view of it, creating images 200 times larger than Hubble.

It would be aimed at surveying other objects in space, Sirianni said.

The rare sight of a Wolf-Rayet star – among the most luminous, most massive, and most briefly detectable stars known – was one of the first observations made by NASA’s James Webb Space Telescope in June 2022.

He said that with the Roman telescope, a full picture of a galaxy can be taken in one single shot, unlike Hubble which captures parts of galaxies.

The Andromeda galaxy pictures were taken at least 400 times by Hubble and were put together to make a complete picture of the galaxy. Roman would take the large broad view in a single shot.

While 30 years of Hubble captures have provided us with data of 170 terabytes, from James Webb 1,000 terabytes of data is expected to be collected in just five years. 

However, Roman would allow gathering 20,000 terabytes of data in mere five years, the scientists noted, adding that it will allow them to capture billion of galaxies helping scientists create a 3D model of galaxies.

Learning more about cosmos

With these large telescopes, scientists are trying to unravel the hidden mysteries of the universe such as the expansion of the universe, dark matter, dark energy, distances between the galaxies and measurement of the distances among different galaxies. 

By acquiring more insights with the help of this modern technological equipment, it may allow scientists to modify theories of space.

Exploration of other solar systems

Among other things, one of the crucial purposes of the Roman telescope is to detect other solar systems with the help of gravitational microlensing.

“If two stars align to each other, the one in front will distort and magnify the light of the star behind. And if the star in the foreground has a planet, we will see the impact of that planet on the light of the star behind it,” Sirianni shared.

He also added that it will provide a “very good” census of how many stars will have exoplanets and the nearest stars of these exoplanets with the help of coronagraph, allowing Roman to take images of Jupiter-like planets with image quality corrections.

If it is successful, it will provide a bottom line to determine the Earth-like plants in other solar systems.

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

on

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
