Using the James Webb Space Telescope, space scientists have discovered a small galaxy more than 13 billion years in the past, which formed stars at an exceptionally high rate for its size.
The findings, published in the journal Science, could provide valuable insights into galaxies that were created soon after the inception of the universe.
The telescope's extensive capabilities allowed researchers on the team — led by University of Minnesota, Twin Cities — to observe the galaxy in unprecedented detail.
Senior author and assistant professor Patrick Kelly said: “This galaxy is far beyond the reach of all telescopes except the James Webb and these first-of-their-kind observations are spectacular.”
Gravitational lensing, a phenomenon in which mass bends and magnifies light, enabled the researchers to locate and study the small galaxy, which appeared 20 times brighter than it would without the lensing effect.
Spectroscopy was then used to measure the galaxy's distance and physical properties.
Hayley Williams, the paper's first author and PhD student at the Minnesota Institute for Astrophysics, said: “This discovery can help us learn more about the characteristics of those first galaxies, how they differ from nearby galaxies and how the earlier galaxies formed.”
The James Webb's ability to collect about 10 times more light than the Hubble Space Telescope and its sensitivity to redder, longer wavelengths in the infrared spectrum have opened up new opportunities for research.
James Webb Space Telescope's advanced capabilities
The James Webb Space Telescope (JWST) is a state-of-the-art space observatory, which started operating on December 25, 2021, as a collaborative effort between Nasa, the European Space Agency and the Canadian Space Agency.
It is regarded as the scientific successor to the Hubble, with advanced capabilities designed to explore deeper into the cosmos and uncover new information about the origins of the universe.
The JWST's primary mirror spans 6.5 metres, significantly larger than the Hubble's 2.4m version. This larger mirror enables the JWST to collect more light, making it highly sensitive and allowing it to observe dimmer and more distant objects with unprecedented clarity.
The telescope is optimised for infrared observations, enabling it to "see" through cosmic dust and study the first galaxies, stars and black holes.
Its cutting-edge instruments help to capture high-resolution images, analyse light spectra and gather data on a wide range of cosmic phenomena, from star and galaxy formation to the characterisation of planets outside the solar system.
Positioned nearly 1.5 million kilometres from Earth, the telescope's sunshield, about the size of a tennis court, protects its sensitive instruments during solar orbit from the Sun's heat and light, maintaining optimal operating temperatures.
The JWST has been designed for a mission life of at least 10 years, with potential for extension. Its scientific discoveries are expected to revolutionise our understanding of the universe and address some of the fundamental questions in astronomy and astrophysics.

“When you sweat a lot, you lose a lot of salt and other electrolytes from your body. If your electrolytes drop enough, you will be at risk of cramping. To prevent salt deficiency, simply add an electrolyte mix to your water.”
Cornelia Gloor, head of RAK Hospital’s Rehabilitation and Physiotherapy Centre
“Don’t make the mistake of thinking you can ride as fast or as far during the summer as you do in cooler weather. The heat will make you expend more energy to maintain a speed that might normally be comfortable, so pace yourself when riding during the hotter parts of the day.”

Going grey? A stylist's advice
If you’re going to go grey, a great style, well-cared for hair (in a sleek, classy style, like a bob), and a young spirit and attitude go a long way, says Maria Dowling, founder of the Maria Dowling Salon in Dubai.
It’s easier to go grey from a lighter colour, so you may want to do that first. And this is the time to try a shorter style, she advises. Then a stylist can introduce highlights, start lightening up the roots, and let it fade out. Once it’s entirely grey, a purple shampoo will prevent yellowing.
“Get professional help – there’s no other way to go around it,” she says. “And don’t just let it grow out because that looks really bad. Put effort into it: properly condition, straighten, get regular trims, make sure it’s glossy.”

Some of Darwish's last words
"They see their tomorrows slipping out of their reach. And though it seems to them that everything outside this reality is heaven, yet they do not want to go to that heaven. They stay, because they are afflicted with hope." - Mahmoud Darwish, to attendees of the Palestine Festival of Literature, 2008
His life in brief: Born in a village near Galilee, he lived in exile for most of his life and started writing poetry after high school. He was arrested several times by Israel for what were deemed to be inciteful poems. Most of his work focused on the love and yearning for his homeland, and he was regarded the Palestinian poet of resistance. Over the course of his life, he published more than 30 poetry collections and books of prose, with his work translated into more than 20 languages. Many of his poems were set to music by Arab composers, most significantly Marcel Khalife. Darwish died on August 9, 2008 after undergoing heart surgery in the United States. He was later buried in Ramallah where a shrine was erected in his honour.

TERMINAL HIGH ALTITUDE AREA DEFENCE (THAAD)
What is THAAD?
It is considered to be the US's most superior missile defence system.
Production:
It was created in 2008.
Speed:
THAAD missiles can travel at over Mach 8, so fast that it is hypersonic.
Abilities:
THAAD is designed to take out ballistic missiles as they are on their downward trajectory towards their target, otherwise known as the "terminal phase".
Purpose:
To protect high-value strategic sites, such as airfields or population centres.
Range:
THAAD can target projectiles inside and outside the Earth's atmosphere, at an altitude of 150 kilometres above the Earth's surface.
Creators:
Lockheed Martin was originally granted the contract to develop the system in 1992. Defence company Raytheon sub-contracts to develop other major parts of the system, such as ground-based radar.
UAE and THAAD:
In 2011, the UAE became the first country outside of the US to buy two THAAD missile defence systems. It then stationed them in 2016, becoming the first Gulf country to do so.
