James Webb Space Telescope images reveal the wonders of the universe

Published

on

It is no exaggeration to say the James Webb Space Telescope (JWST) represents a new era for modern astronomy.

Launched on December 25 last year and fully operational since July, the telescope offers glimpses of the universe that were inaccessible to us before. Like the Hubble Space Telescope, the JWST is in space, so it can take pictures with stunning detail free from the distortions of Earth’s atmosphere, interestingengineering.com reported.

However, while Hubble is in orbit around Earth at an altitude of 540km, the JWST is 1.5 million kilometers distant, far beyond the Moon. From this position, away from the interference of our planet’s reflected heat, it can collect light from across the universe far into the infrared portion of the electromagnetic spectrum.

This ability, when combined with the JWST’s larger mirror, state-of-the-art detectors, and many other technological advances, allows astronomers to look back to the universe’s earliest epochs.

As the universe expands, it stretches the wavelength of light traveling toward us, making more distant objects appear redder. At great enough distances, the light from a galaxy is shifted entirely out of the visible part of the electromagnetic spectrum to the infrared. The JWST is able to probe such sources of light right back to the earliest times, nearly 14 billion years ago, read the report.

According to interestingengineering.com, the Hubble telescope continues to be a great scientific instrument and can see at optical wavelengths where the JWST cannot. But the Webb telescope can see much further into the infrared with greater sensitivity and sharpness.

The website has highlighted ten images that have demonstrated the staggering power of this new window to the universe.

1. Mirror alignment complete


Despite years of testing on the ground, an observatory as complex as the JWST required extensive configuration and testing once deployed in the cold and dark of space.

One of the biggest tasks was getting the 18 hexagonal mirror segments unfolded and aligned to within a fraction of a wavelength of light. In March, NASA released the first image (centered on a star) from the fully aligned mirror. Although it was just a calibration image, astronomers immediately compared it to existing images of that patch of sky – with considerable excitement.

2. Spitzer vs. MIRI


This early image, taken while all the cameras were being focused, clearly demonstrates the step change in data quality that JWST brings over its predecessors.

On the left is an image from the Spitzer telescope, a space-based infrared observatory with an 85cm mirror; the right, the same field from JWST’s mid-infrared MIRI camera and 6.5m mirror. The resolution and ability to detect much fainter sources is on show here, with hundreds of galaxies visible that were lost in the noise of the Spitzer image. This is what a bigger mirror situated out in the deepest, coldest dark can do.

3. The first galaxy cluster image


The galaxy cluster with the prosaic name of SMACS J0723.3–7327 was a good choice for the first color images released to the public from the JWST.

The field is crowded with galaxies of all shapes and colors. The combined mass of this enormous galaxy cluster, over 4 billion light years away, bends space in such a way that light from distant sources in the background is stretched and magnified, an effect known as gravitational lensing.

These distorted background galaxies can be clearly seen as lines and arcs throughout this image. The field is already spectacular in Hubble images (left), but the JWST near-infrared image (right) reveals a wealth of extra detail, including hundreds of distant galaxies too faint or too red to be detected by its predecessor.

4. Stephan’s Quintet


These images depict a spectacular group of galaxies known as Stephan’s Quintet, a group that has long been of interest to astronomers studying the way colliding galaxies interact with one another gravitationally.

On the left we see the Hubble view, and the right the JWST mid-infrared view. The inset shows the power of the new telescope, with a zoom-in on a small background galaxy. In the Hubble image we see some bright star-forming regions, but only with the JWST does the full structure of this and surrounding galaxies reveal itself.

5. The Pillars of Creation


The so-called Pillars of Creation is one of the most famous images in all of astronomy, taken by Hubble in 1995. It demonstrated the extraordinary reach of a space-based telescope.

It depicts a star-forming region in the Eagle Nebula, where interstellar gas and dust provide the backdrop to a stellar nursery teeming with new stars. The image on the right, taken with the JWST’s near-infrared camera (NIRCam), demonstrates a further advantage of infrared astronomy: the ability to peer through the shroud of dust and see what lies within and behind.

6. The ‘Hourglass’ Protostar


This image depicts another act of galactic creation within the Milky Way. This hourglass-shaped structure is a cloud of dust and gas surrounding a star in the act of formation – a protostar called L1527.

Only visible in the infrared, an “accretion disk” of material falling in (the black band in the center) will eventually enable the protostar to gather enough mass to start fusing hydrogen, and a new star will be born.

In the meantime, light from the still-forming star illuminates the gas above and below the disk, making the hourglass shape. Our previous view of this came from Spitzer; the amount of detail is once again an enormous leap ahead.

7. Jupiter in infrared


The Webb telescope’s mission includes imaging the most distant galaxies from the beginning of the universe, but it can look a little closer to home as well.

Although JWST cannot look at Earth or the inner Solar System planets – as it must always face away from the Sun – it can look outward at the more distant parts of our Solar System. This near-infrared image of Jupiter is a beautiful example, as we gaze deep into the structure of the gas giant’s clouds and storms. The glow of auroras at both the northern and southern poles is haunting.

This image was extremely difficult to achieve due to the fast motion of Jupiter across the sky relative to the stars and because of its fast rotation. The success proved the Webb telescope’s ability to track difficult astronomical targets extremely well.

8. The Phantom Galaxy


These images of the so-called Phantom Galaxy or M74 reveal the power of JWST not only as the latest and greatest of astronomical instruments but as a valuable complement to other great tools. The middle panel here combines visible light from Hubble with infrared from Webb, allowing us to see how starlight (via Hubble) and gas and dust (via JWST) together shape this remarkable galaxy.

Much JWST science is designed to be combined with Hubble’s optical views and other imaging to leverage this principle.

9. A super-distant galaxy


Although this galaxy – the small, red blob in the right image – is not among the most spectacularly picturesque our universe has to offer, it is just as interesting scientifically.

This snapshot is from when the universe was a mere 350 million years old, making this among the very first galaxies ever to have formed. Understanding the details of how such galaxies grow and merge to create galaxies like our own Milky Way 13 billion years later is a key question, and one with many remaining mysteries, making discoveries like this highly sought after.

It is also a view only the JWST can achieve. Astronomers did not know quite what to expect; an image of this galaxy taken with Hubble would appear blank, as the light of the galaxy is stretched far into the infrared by the expansion of the universe.

10. This giant mosaic of Abell 2744


This image is a mosaic (many individual images stitched together) centered on the giant Abell 2744 galaxy cluster, colloquially known as “Pandora’s Cluster”. The sheer number and variety of sources that the JWST can detect are mind-boggling; with the exception of a handful of foreground stars, every spot of light represents an entire galaxy.

In a patch of dark sky no larger than a fraction of the full Moon there are umpteen thousands of galaxies, really bringing home the sheer scale of the universe we inhabit.

Professional and amateur astronomers alike can spend hours scouring this image for oddities and mysteries.

Over the coming years, JWST’s ability to look so deep and far back into the universe will allow us to answer many questions about how we came to be. Just as exciting are the discoveries and questions we cannot yet foresee. When you peel back the veil of time as only this new telescope can, these unknown unknowns are certain to be fascinating, interestingengineering.com reported.

Swirling, vortex-like patterns observed on the sun’s surface

The researchers said the observations may provide insight into underlying physical processes that impact ⁠the dynamics of the sun and other stars, including eruptions from the solar surface that can interfere with the operation of satellites, GPS navigation, power grids and global communications on ​Earth.

Astronomers have obtained the highest-resolution images to date of our sun’s visible surface, observing swirling, vortex-like patterns in superheated solar gases reminiscent of the shapes depicted in ​the nocturnal sky in Vincent van Gogh’s 1889 painting “The Starry Night.”

The researchers made the observations of a portion of the sun’s photosphere, a relatively thin ‌layer — about 60 miles (100 km) in depth compared to the overall solar diameter of roughly 865,000 miles (1.4 million km) — using the U.S. National Science Foundation’s Hawaii-based Daniel K. Inouye Solar Telescope, Reuters reported.

The still images and time-lapse video reveal continuously growing whirls of hot plasma, gas heated to temperatures so high that subatomic particles called electrons break free from atoms and form a broth of charged particles. The observed whirls are large on ​a human scale but small on the scale of a stellar surface, with diameters ranging from about 12 miles (19 km) — the minimum scale detectable by the world’s ​most powerful solar telescope — up to roughly 100 miles (170 km).

The researchers said the observations may provide insight into underlying physical processes that impact ⁠the dynamics of the sun and other stars, including eruptions from the solar surface that can interfere with the operation of satellites, GPS navigation, power grids and global communications on ​Earth.

The curly, circular patterns do not represent random shapes, but rather are the first detection of a phenomenon called Kelvin-Helmholtz instability, or KHI, on the surface of a star. KHI, first described ​in the 19th century, refers to a dynamic process that happens when two parallel streams of fluids or gases interact while moving at different velocities.

“The interface can become unstable and develop wave-like vortices that grow in size until they break apart, not unlike waves out on a lake or out on the ocean in windy conditions,” said astronomer Friedrich Wöger, a senior scientist at the National Science Foundation’s National Solar Observatory ​in Colorado, the Inouye telescope’s instrument program scientist, and co-lead author of the study published on Wednesday in the journal Nature.

Swirling clouds caused by KHI are a well-known, albeit rare, meteorological ​occurrence on Earth, and also have been observed in the atmospheres of the giant gas planets Jupiter and Saturn, Wöger said.

“The difference from the waves and clouds we know here on Earth is that the two ‌interacting fluids ⁠are hot plasma — about 6,000 degrees Kelvin and 10,000 degrees Fahrenheit (5,540 degrees Celsius) — moving within a magnetic field that helps create the conditions for the instability to develop,” Wöger said.

By twisting the solar magnetic field, KHI creates energy that can suddenly unleash an explosion.

‘A TRUE GAME-CHANGER’

Wöger called the discovery of solar KHI “a true game-changer,” saying it opens up a new framework for understanding how the sun energizes its atmosphere.

“The sun and sun-like stars are extremely dynamic systems, characterized by a whole spectrum of rapid, explosive events within their magnetic elements. How these explosions ​are triggered is one of the main frontiers ​in modern solar physics,” National Solar Observatory ⁠astronomer and study co-lead author David Kuridze said.

The KHI manifestation might help explain why the sun’s outer atmosphere becomes as hot as it does and why magnetic energy accumulates and moves around on the solar surface.

The constant twisting motions generated by KHI can gradually build the ​energy required to trigger coronal mass ejections and solar flares, Kuridze said. Coronal mass ejections are huge bubbles of gas threaded with ​magnetic field lines that ⁠are expelled from the sun’s surface. Solar flares are gigantic explosions on the sun that propel light, energy and high-speed particles into space.

Aside from the science, the researchers admired the beauty of the new close-up views of the sun.

“Maybe ‘magnificent’ comes closest to describing the aesthetics in the images for us,” Wöger said.

“Interestingly, artists have long captured this fluid dynamic intuition in their work. A famous ⁠example is Van ​Gogh’s ‘The Starry Night,’ where the sky’s vortex structures closely resemble turbulent KHI structures,” Kuridze said. “A similar parallel appears ​in Hokusai’s famous woodblock print, ‘The Great Wave off Kanagawa,’ where the curling crests of the wave echo the iconic shape of KHI billows. It shows how the fundamental geometry of nature deeply resonates with human art.”

Afghanistan currently transits internet traffic to Central Asia, says MCIT

Published

on

Afghanistan is currently serving as a transit route for internet traffic between South Asia and Central Asia, the Ministry of Communications and Information Technology (MCIT) said, highlighting the country’s growing role in regional digital connectivity.

The ministry said fiber-optic traffic from several South Asian countries is routed through Afghanistan to Central Asian nations via the country’s fiber-optic network.

According to the ministry, nearly $3 billion has been invested in Afghanistan’s fiber-optic and telecommunications sector so far, with expansion efforts continuing.

Officials said Afghanistan offers significant investment opportunities in telecommunications and fiber-optic infrastructure. They added that, alongside expanding domestic communications services, the ministry is working to enhance the country’s capacity to provide transit services for regional countries.

The ministry said Afghanistan is already facilitating the transit of internet traffic from parts of South Asia to Central Asia and stressed that the country’s strategic geographic location positions it as an important digital corridor between the two regions.

“We are currently transiting internet traffic through Afghanistan to South Asian and Central Asian countries,” said Enayatullah Alokozai, spokesperson for the Ministry of Communications and Information Technology. “Afghanistan is a suitable geographical corridor for data transmission.”

Economic analysts say Afghanistan has the potential to become a key hub for regional connectivity. They noted that, in addition to serving as a corridor for energy transmission from Central Asia, the country could also facilitate the large-scale transit of fiber-optic connectivity, internet traffic, and commercial goods.

Representatives of the private sector also said Afghanistan has strong potential to attract further investment in telecommunications and fiber-optic infrastructure. They noted that numerous domestic and international companies are active in the sector, creating direct employment opportunities for thousands of Afghans.

New AI tool helps Afghans identify visa pathways

Published

on

A veteran-led organisation has launched a new artificial intelligence-powered platform designed to help Afghans navigate complex visa and relocation options as thousands remain stranded or at risk nearly five years after the withdrawal of U.S. forces from Afghanistan.

The Visa Pathways and Relocation Information Center (V-PRIC), developed by AfghanEvac, uses artificial intelligence to guide users through possible immigration and protection pathways based on their individual circumstances.

According to AfghanEvac founder and U.S. Navy veteran Shawn VanDiver, the platform attracted more than 30,000 visits during its first week online.

Users begin by answering questions about their current location, whether they worked with the United States, whether they face security risks, and by providing a brief description of their situation. The system then compares that information with a database covering 124 U.S. visa and immigration categories, including 16 relevant to Afghan applicants, as well as relocation options offered by other countries.

VanDiver said the platform is intended to simplify what is often a confusing and constantly changing immigration process. Before using the service, applicants must acknowledge that it does not provide legal advice.

The launch comes as many Afghans who supported the U.S. during its two-decade military presence continue to face uncertainty. AfghanEvac says policy changes have significantly reduced available relocation opportunities, leaving many applicants unable to progress with immigration cases.

According to the organisation, around 1,100 Afghan allies and their family members remain at the Camp As Sayliyah processing facility in Doha, Qatar, despite many having previously received approval to enter the United States. AfghanEvac says travel restrictions have prevented them from completing the process.

VanDiver said the new tool helps users identify obstacles affecting their applications, including whether delays are caused by legal requirements or government policy, while also highlighting possible next steps.

The platform has been trained using legal decisions, executive orders, policy documents and information gathered through AfghanEvac surveys and guidance materials. The organisation says it will continue updating the system as immigration policies evolve.

VanDiver said the tool could also help applicants avoid actions that may complicate future immigration cases, such as pursuing visa interviews when programmes are temporarily suspended.

AfghanEvac recently surveyed more than 1,100 Afghans between January and July this year. Of the 427 respondents still inside Afghanistan, nearly half reported facing direct security threats. Another 427 respondents were in Pakistan awaiting relocation, with many expressing concerns about possible deportation and limited access to healthcare.

The organisation emphasised that the AI platform is intended to complement, rather than replace, professional legal assistance. It encourages applicants to seek legal advice while using the service to better understand the immigration options available to them.
