India's teenage prodigy, Vaibhav Sooryavanshi , was in attendance among the country's Asian Games 2026 stars at Major Dhyan Chand Stadium in Delhi Thursday as Prime Minister Narendra Modi felicitated the contingent. Sooryavanshi was a part of the Indian men's cricket team that won the gold medal in Tokyo. During the ceremony, PM Modi gave a riveting speech that also captured how 15-year-olds are winning medals for the country at grand events such as the Asian Games. The remark drew a smile even on the face of Sooryavanshi. PM Modi could not stop hailing the Indian athletes during the felicitation ceremony, including the cricketers, hockey teams, and boxers, whilst lauding the records that were broken in the Aichi-Nagoya Asian Games and the historic milestones that were achieved. As PM Modi continued his speech, he made a special mention of the 15 and 17-year-olds who won medals for India at the Games. Although he did not mention Sooryavanshi by name, the mention did see...
Asteroid collisions with Earth are surprisingly common, with NASA estimating 48.5 tonnes of meteoric material entering our atmosphere daily. Most burn up, producing shooting stars. Although devastating asteroid impacts are rare in Earth's history, humanity has learned a crucial lesson from the catastrophic event 66 million years ago. The asteroid responsible for the dinosaurs' extinction was approximately six miles wide, but significantly smaller objects still pose a significant threat. In the face of potentially catastrophic asteroid impacts, scientists are racing to develop innovative solutions to protect our planet.
In New Mexico, scientists are exploring a futuristic solution to defend Earth against asteroid threats: harnessing X-ray blasts from nuclear explosions, the Guardian reported. Scientists at Sandia National Laboratories in Albuquerque have successfully demonstrated a revolutionary method to deflect incoming asteroids using nuclear explosions. For the experiment, researchers harnessed the power of X-rays from a nuclear blast to vaporise the surface of a nearby asteroid.
The process works by unleashing an immense pulse of radiation, heating the asteroid's surface to tens of thousands of degrees. This creates a rapidly expanding ball of gas that can nudge the asteroid off its catastrophic course. By precisely calculating the blast's impact, scientists believe this technique can effectively push threatening asteroids away from Earth, potentially saving humanity from doomsday.
"The primary mechanism involves using X-rays to rapidly heat the target surface, causing it to vaporize and expand into the adjacent vacuum. The expanding gas pushes against the asteroid, transferring momentum (in the opposite direction)," authors of the study published Monday in the journal Nature Physics wrote.
Scientists noted that the nuclear option is for larger asteroids, particularly when time is short. Researchers believe this strategy can effectively deflect asteroids up to 2.5 miles wide, although this isn't a rigid limit.
“If there is enough warning time, one can certainly deflect larger asteroids,” Dr Nathan Moore, the first author of the study said.
Mr Moore and his team plan to conduct further experimental tests to refine the X-ray deflection technique, building on their initial success. Their goal is to enhance the method's effectiveness through additional laboratory experiments. Ultimately, they envision a space-based demonstration, similar to NASA's DART (Double Asteroid Redirection Test) mission, to test the technique on a real asteroid.
