Glowing streaks of light and warped arcs: Nasa gives glimpse at ‘distant past' through new Webb picture
Galaxy cluster Abell S1063 (Nasa)
As part of the 'picture of the month' series, Nasa has revealed a new image taken by the
James Webb telescope
that gives a look into the distant past. This picture of the
galaxy cluster
Abell S1063 is a gigantic collection of galaxies lying 4.5 billion
light years
from Earth as part of the constellation Grus, also known as the Crane.
The picture showcases galaxies surrounded by glowing streaks of light and warped arcs, which are of particular interest to scientists, as they represent faint galaxies from the distant past of this universe. Captured after 120 hours of observation, this image represents Webb's deepest look at a single celestial target.
This image is a
deep field image
, capable of capturing pictures of galaxies that have existed as early as 200 million years after the Big Bang. Deep field technology comprises of long exposure photography, focusing on a singular area in the sky, capable of collecting as much light as possible to draw out images of the most distant and faraway galaxies.
The Abell cluster was initially observed by the Nasa/ESA Hubble Telescope, a strong gravitational lens, with an aim to use the cluster's image to study the
early Universe

Upon studying, the image reveals a plethora of lensing arcs around the Abell S1063, providing a peek at previously unseen features and a multitude of faint galaxies.
This observation is part of the GLIMPSE programme, which has a mission to study a period called the '
Cosmic Dawn
' when the universe was only a few million years old. Studying images captured through
gravitational lensing
has the power to enrich our understanding of the universe and the emergence of the very first galaxies.

How India And Israel Are Reaching For The Stars
Group Captain Shubhanshu Shukla is set for the Axiom 4 mission to the International Space Station (ISS), with Israeli astronaut Eytan Stibbe helping bring the excitement of space to students at the Indian astronaut's school in Uttar Pradesh's Lucknow. The two spacefarers, after an interaction at a gathering in Houston, had envisioned a program that would allow Indian students to experience the thrill of space exploration in real time. "Every year, there's a gathering of astronauts in Houston, where NASA's main human spaceflight centre is based. That's where I met Group Captain Shukla. He told me about his mission, and I shared how we had engaged school children in Israel during my time on the ISS. He immediately suggested we reach out to the City Montessori School in Lucknow," Mr Stibbe said. The City Montessori School is where Mr Shukla studied. Plans are now underway to create a parallel "mission control" experience at the school, allowing students to follow Mr Shukla's journey aboard the ISS, watch live feeds from the station, and participate in interactive educational activities. "The idea is to create programs, materials, and excitement," Mr Stibbe, who was part of the Axiom 1 mission in 2022, said. "We want children to ask questions, to be curious. During the mission, they'll be able to watch Shukla at work on the station-not just during interviews, but through continuous camera feeds that show astronauts floating, working, and living in microgravity. It's super exciting," he said. Mr Stibbe, who funded his private mission to space, is passionate about making space accessible to all. His outreach efforts in Israel reached thousands of students, and he hopes to replicate that success in India. "Whatever we did in Israel, we're now extending a hand of friendship to India," he said. "There's a lot we can learn from each other," Mr Stibbe said. "From the educational system, from the missions, and from the science. We're following India's space program closely and hope for more cooperation." The initiative has the potential to draw attention at the highest levels. "Prime Minister Benjamin Netanyahu and Prime Minister Narendra Modi are great friends," Mr Stibbe said. "If they get the opportunity, I'm sure they would be happy to join in. We'll definitely extend an invitation." For Mr Stibbe, the mission is personal. "Watching the Earth from space, seeing the sunrise and sunset - it changes you. You realise how fragile our planet is. That's why I believe in sustainability and in inspiring the next generation to care for our world," he said. "India and Israel," Mr Stibbe said with a smile, "the friendship goes beyond Earth - and on Earth."

Shubhanshu Shukla set to script history as India's second astronaut in space
India's Shubhanshu Shukla is set for his maiden space flight as part of Axiom Space 's fourth commercial mission to the International Space Station, which is scheduled for lift-off onboard SpaceX's Falcon-9 rocket from the Kennedy Space Centre in Florida on June 8. The launch of the Dragon spacecraft will take place not earlier than 6:41 pm IST from NASA's spaceport in Florida, making Shukla only the second Indian to travel to space four decades after Rakesh Sharma's iconic spaceflight onboard Russia's Soyuz spacecraft in 1984. Besides Shukla, the mission pilot for the Axiom-4 mission, the other crew include Slawosz Uznanski-Wisniewski from Poland and Tibor Kapu from Hungary, marking both European nation's first travel to the International Space Station in history and the second government-sponsored human spaceflight mission in over 40 years. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Gain expertise in Deep Learning & NLP with AI & ML BITS Pilani WILP Apply Now Undo Veteran US astronaut Peggy Whitson will be the commander of the Axiom-4 mission. "I am really, really excited to go into microgravity and experience spaceflight on my own," Shukla, who goes by the nickname 'Shuks', said at a press conference in January. Live Events Once docked, the astronauts plan to spend up to 14 days aboard the orbiting laboratory, conducting science, outreach, and commercial activities. The Ax-4 astronauts will perform around 60 scientific studies and activities representing 31 countries during their 14-day stay at the ISS . Shukla is set to conduct exclusive food and nutrition-related experiments developed under a collaboration between the Indian Space Research Organisation (ISRO) and the Department of Biotechnology (DBT), with support from NASA. The experiments aim to pioneer space nutrition and self-sustaining life support systems vital for future long-duration space travel. ISRO has lined up a set of seven experiments for Shukla, who will also participate in five joint studies planned by NASA for its human research program. It has drawn up plans to focus on India-centric food for carrying out experiments on the ISS, including sprouting methi (Fenugreek) and moong (green gram) in microgravity conditions. Shukla will also expose the seeds to the macrobiotic conditions and bring them back to earth where they will be cultivated in plants not just once but over generations. In January, Shukla said he also planned to capture his experiences on board the ISS through pictures and videos which can be shared with all the "'Bharatvaasis' back home." "I want them to share this thrilling experience through my eyes, for I truly believe that, even as an individual travelling to space, this is the journey of 1.4 billion people," he said. Shukla said he planned to take certain items from different parts of the country with him to the ISS during the 14-day mission and even expressed hope to serve Indian food to astronauts in the orbital laboratory. He said the experience on the Axiom Mission 4 would be very well utilised on the Gaganyaan mission which is planned for 2027. ISRO is spending Rs 550 crore on the Axiom-4 mission.
