James Webb Telescope captures amazing pictures of Uranus

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 has never looked better. Really.

Only Voyager 2 and Keck (with adaptive optics) have imaged the planet's faintest rings before, and never as clearly as Webb’s first glimpse at this ice giant, which also highlights bright atmospheric features. https://t.co/aE3rJIqVKy pic.twitter.com/RZElIRkudl

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.

Uranus rotates on its side, causing its poles to experience 42 years of sunlight & 42 years of darkness. (It takes 84 years to orbit the Sun.) Voyager flew by Uranus in 1986 when it was summer at its south pole. Now the south pole is out of view, facing the darkness of space.

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.

After changing its display colour from blue to green, WhatsApp, which was before well-known for its blue motif, caused its users to hold divergent views.

New upgrades to the Meta app always spark a lot of discussion, regardless of how big or small the changes are.

Still, Meta-owned WhatsApp hopes that these modifications would “make it more accessible as well as easier to use” and offer a “modern, new experience” with relation to the updated display color.

A statement from the firm claimed that they had altered WhatsApp’s “looks and feels, including spacing, colors, icons, and more.”

Both iOS and Android users can now view the new WhatsApp update; the green tint on the latter has changed from the previous version.

However, iPhone users will notice that every display element, including the chat-list window and status bar, has changed with the recent design update. WhatsApp used to have a blue color scheme on iPhones.

Furthermore, the formerly blue links shared within the app are now displayed in green.

In addition, WhatsApp has made other improvements to improve its user experience outside of the color shift.

On Tuesday,Tuesday, while presiding over a review meeting on solar household solutions, the CM gave the order to begin the installation of one kilowatt solar systems right away. She also gave the order to introduce the newest solar systems.

Phase-I solar systems would be balloted for by 50,000 protected users who use 100 units each month, at a cost of Rs 12.6 billion.

Home-based solar systems will eventually be made available to other Punjabi consumers. A solar system will consist of a battery, inverter, sophisticated solar plate, and more related accessories.

Attending the meeting were Provincial Information Minister Azma Zahid Bukhari, MPA Sania Ashiq, Former Senator Pervaiz Rashid, Chief Secretary, Chairman Planning and Development, Secretaries of Energy, Finance, and Punjab Power Development Board (PPDB) Managing Director, in addition to other pertinent officers.

During his inaugural speech as Punjab’s chief minister, Maryam Nawaz outlined her five-year plan and promised to develop a strategy for customers who use fewer than 300 units of power.

According to Maryam Nawaz, the PML-N’s main goals for her term will be to provide jobs, healthcare, and education.

She said, “I am working on a plan to provide solar panels to consumers using up to 300 units of electricity or less in installments.”

The discussion on the province’s capital city’s beautification was chaired by Chief Minister Ali Amin Gandapur.

CM Gandapur gave the pertinent authorities instructions at the meeting to complete the arrangements and submit the free WiFi service plan for the province government’s approval.

In the following phase, he said, the service will be extended to more cities. In addition, the chief minister gave the Peshawar Development Authority instructions to create a beatification plan for the city.

The meeting voted to launch a Bus Rapid Transit (BRT) service on Nasir Bagh Road in the province capital with the goal of facilitating the easy mobility of the population.

CM Gandapur pushed for the installation of underpasses rather than overhead bridges and ordered the city’s street lights to be converted to solar power.

The chief minister gave the order to begin work on the road around the BRT Corridor at University Road as well as the building of the remaining section of Warsak-Nasir Bagh Road right away.

In order to promote KP’s culture, he also oversaw the installation of fake plants on all road walks and painted headbridges and walls with designs.
