James Webb Telescope captures amazing pictures of Uranus

Published

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.

How to avoid falling victim to scammers on WhatsApp groups

Smartphone users occasionally find themselves in a difficult situation when they are part of multiple WhatsApp groups.

To his annoyance, a user is typically added to dozens of WhatsApp groups for friends, family, and the office. This is because his phone rings every other second from the constant barrage of forwarded messages.

But these days, scammers are busy in WhatsApp groups, coming up with novel ways to con people.

After joining a WhatsApp group, a man lost INR 16 lakh to scammers, according to a startling disclosure.

Reports from the Indian media state that the event took place in Mangaluru and that the victim was deceived into joining a WhatsApp group by an unidentified individual.

The victim clicked on a dubious link and was duped into downloading a malicious program after being seduced with promises of large rewards in share market investing.

Hoping for large rewards, the victim transferred INR 16.9 lakh to the scammer’s bank account.

The victim discovered he had been duped, however, when he attempted to withdraw the money and was unable.

A clear reminder of the dangers of believing unidentified links and promises made online is provided by this instance.

Advice for Guarding Against These Scams:

Be cautious of unknown links and apps.
Avoid unverified investments with promises of high returns.
Research before downloading apps.
Enable two-factor authentication for added security.

Report suspicious activities to the platform or local police.

Google claims that its new chip has solved a quantum computing problem.

Google announced on Monday that it had solved a complex quantum computing problem in five minutes using a new generation of chips, which would have taken a classical computer a longer time than the universe’s history.

Alphabet’s Google is pursuing quantum computing, like other corporate behemoths like Microsoft and International Business Machines (IBM), because it promises to achieve computer speeds that are significantly quicker than those of the most advanced systems available now. While there are currently no commercial applications for the arithmetic problem solved by the company’s Santa Barbara, California, quantum lab, Google expects that quantum computers can eventually solve issues in artificial intelligence, medicine, and battery chemistry that are beyond the capabilities of current computers.

A new chip named Willow, which has 105 “qubits,” the fundamental units of quantum computers, produced the findings that were made public on Monday. Despite their speed, qubits are prone to errors because they can be jostled by subatomic particles or events in space.

A semiconductor may become no more advanced than a standard computer chip when more qubits are crammed onto it. Scientists have been working on quantum error correction since the 1990s.

Google said in an article published Monday in the journal Nature that it has discovered a method to connect the qubits of the Willow chip in such a way that error rates decrease with increasing qubit count. Additionally, the business claims that it can instantly fix mistakes, which is a crucial step in making its quantum machines workable.

In an interview, Hartmut Neven, the head of Google’s Quantum AI division, stated, “We are past the break-even point.”

Using differing technical assumptions about a classical system, IBM contested Google’s claim in 2019 that its quantum processor solved a problem that would take a conventional computer 10,000 years, claiming that the problem could be solved in two and a half days.

Google says it considered some of those worries in its most recent projections in a blog post on Monday. Google claimed that a traditional computer would still require a billion years to achieve the same outcomes as its newest chip, even in the most optimistic circumstances.

In an interview, Anthony Megrant, principal architect for Google Quantum AI, stated that while some of Google’s competitors are manufacturing circuits with more qubits than Google, Google is concentrated on creating the most dependable qubits possible.

Prior to creating its own specialized fabrication facility to create its Willow chips, Google used a shared facility at the University of California, Santa Barbara. The new facility, according to Megrant, would increase the speed at which Google can produce future chips, which are kept cold in enormous freezers known as cryostats for experimental purposes.

“If we have a good idea, we want somebody on the team to be able to… get that into the clean room and into one of these cryostats as fast as possible, so we can get lots of cycles of learning,” Megrant explained.

In its beta edition, WhatsApp offers reminder reminders for unseen status updates.

Published

For overlooked status changes, Meta’s well-known social messaging app WhatsApp has introduced a new reminder notification option.

Previously in testing, this functionality is now available to Android users who are engaged in WhatsApp’s beta program. WhatsApp for Android’s 2.24.25.29 beta version has the feature, which notifies users of unseen status updates and unread messages.

Users can access the “Settings” menu, select “Notifications,” and then go to the “Reminders” option to enable or disable the feature.

An internal mechanism is used to choose which contacts would receive these notifications, according to WABetaInfo. Contacts with whom users communicate the most are given priority by this algorithm. The data is not saved on the server or in backups, so if the user reinstalls the application, the algorithm is reset.

Some people think that the function would be more useful if it allowed users to personalise notifications for specific contacts, even if it is intended to alert users of updates from their most-interacted contacts.

Joining the beta program offers early access to this update for individuals who are keen to test it out before the stable release.
