Mega collision in Milky Way galaxy fractured its bone. We have a picture
Astronomers have discovered a huge fracture in the cosmic bone of the Milky Way galaxy and Nasa has released an image of what it appears like.X-ray data from Chandra and radio data from the MeerKAT radio array in South Africa show the cosmic bone dubbed G359.13 by Nasa. Nasa researchers looked closely at the mysterious structure and revealed the presence of a break, or fracture, in the otherwise continuous length of G359.13.advertisementAstronomers have discovered an X-ray and radio source at the location of the fracture, using the data from Chandra and MeerKAT and the National Science Foundation's Very Large Array.

The fracture is likely caused by a pulsar that smashed into G359.13 at a speed between one million and two million miles per hour.A pulsar is a highly magnetised, rotating neutron star that emits beams of electromagnetic radiation from its magnetic poles. These beams sweep across space like lighthouse beams, and when one of them points toward Earth, we see a regular pulse of radiation. Typically about 20 kilometres in diameter but more massive than the Sun. They can rotate extremely fast—some spin hundreds of times per second.advertisementThe collision between the pulsar and the cosmic bone happened at a staggering speed of one million and two million miles per hour.

At about 230 light-years long, G359.13 is one of the longest and brightest of these structures in the Milky Way. To put this into context, there are more than 800 stars within that distance from Earth. G359.13 is located about 26,000 light-years from Earth, near the centre of the Milky Way.The details of the findings have been published in the Monthly Notices of the Royal Astronomical Society.Trending Reel

Indian astronaut Shukla Axiom-4 mission set for June 10 lift-off, dock at ISS after 28-hour flight
Indian astronaut Shubhanshu Shukla and three others are set to embark on Axiom Space's fourth human spaceflight from NASA's Kennedy Space Centre in Florida on June 10 and are likely to dock at the International Space Station on June 11 at about 10 PM IST, after a nearly 28-hour journey. Mr. Shukla, the mission pilot of the Axiom-4 (Ax4) commercial mission to the ISS, will be accompanied by mission commander Peggy Whitson and specialists Tibor Kapu from Hungary and Slawosz Uznanski-Wisniewski from Poland. The Axiom-4 mission will mark India's return to space 41 years after Rakesh Sharma's historic spaceflight onboard Russia's Soyuz mission in 1984. "The crew will travel to the orbiting laboratory on a new SpaceX Dragon spacecraft after launching on the company's Falcon 9 rocket. The targeted docking time is approximately 12:30 p.m. EDT (10:00 p.m. IST), Wednesday, June 11," NASA said in a statement. ISRO Chairman V. Narayanan visited Axiom Space last week to review the preparations for the spaceflight. The astronauts have been in quarantine since May 25 to prepare for the trip and have been training ahead of the launch on June 10. "The #Ax4 crew undergoes extensive emergency training, featuring a range of scenarios such as underwater escape drills," Axiom Space said in a post on X, and shared a video of the training programme. During the 14-day stay at the ISS, the Ax-4 crew is expected to interact with Prime Minister Narendra Modi, school students, and space industry leaders, among others. Earlier this week, the crew addressed a press conference to give an update on the training ahead of the launch. "We are good for the launch, we have completed all the training and the team has bonded well," Mr. Whitson said on Tuesday (June 3, 2025). Mr. Shukla described the year-long training for the spaceflight as "nothing short of transformative". "It has been an amazing journey so far, but the best is yet to come. As I go into space, I carry not just instruments and equipment, I carry hopes and dreams of a billion hearts," Mr. Shukla said. Mr. 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 Mr. 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. Mr. Shukla will also expose the seeds to the macrobiotic conditions and bring them back to earth, where they will be cultivated into plants not just once but over generations. Mr. Shukla's experience on the Axiom Mission 4 would be very well utilised on the Gaganyaan mission, which is planned for 2027. ISRO is spending ₹550 crore on the Axiom-4 mission.

‘Mega' tsunami of Greenland in 2023 echoed for 9 days, shook sensors worldwide: NASA
A massive rockslide in Greenland in 2023 triggered a rare and persistent 'mega' tsunami that ricocheted within the steep walls of a remote fjord for nine days, according to new satellite data released by NASA and international researchers. The international Surface Water and Ocean Topography (SWOT) satellite mission, a collaboration between NASA and France's CNES (Centre National d'Études Spatiales), detected the tsunami's contours. The event, which unfolded in the Dickson Fjord in eastern Greenland, was captured by the Surface Water and Ocean Topography (SWOT) satellite — a joint mission between NASA and France's CNES — revealing never-before-seen details of how water surged and tilted inside the fjord after the impact. The landslide, which occurred in mid-September 2023, sent over 880 million cubic feet (25 million cubic meters) of rock and ice plunging into the Dickson Fjord, generating a tsunami that lacked space to dissipate. Instead, it bounced back and forth within the confined waterway — rising and falling every 90 seconds. The impact was so powerful that seismic sensors around the world detected the tremors. 'Far from the open ocean, in a confined space, the energy of the tsunami's motion had limited opportunity to dissipate, so the wave moved back and forth about every 90 seconds for nine days. It caused tremors recorded on seismic instruments thousands of miles away,' the article read. Using its high-resolution Ka-band Radar Interferometer (KaRIn), the SWOT satellite measured changes in water elevation from its orbit 560 miles (900 kilometers) above Earth. A flyover on September 17 — just a day after the landslide — showed dramatic tilting in water levels, with the north side of the fjord standing up to 4 feet (1.2 meters) higher than the south. These results were compared with baseline measurements taken weeks earlier, on August 6. 'SWOT happened to fly over at a time when the water had piled up pretty high against the north wall of the fjord,' the article quoted Josh Willis, a sea level researcher at NASA's Jet Propulsion Laboratory in Southern California. The Dickson Fjord, about 1.7 miles (2.7 kilometers) wide and 1,772 feet (540 meters) deep, lies along a remote network of channels on Greenland's rugged east coast. Its towering walls — more than 6,000 feet (1,830 meters) high — helped trap the 'mega' tsunami's energy and keep it churning for more than a week.
