World Asteroid Day 2025: How to watch near-Earth asteroids live on June 30

Hindustan Times30-06-2025
On World Asteroid Day 2025, June 30, space enthusiasts and science lovers around the world can look forward to a special treat. On the 10th anniversary of the observation, a United Nations event will bring real-time views of near-Earth asteroids into people's homes for free. World Asteroid Day 2025 is on June 30
The UN began observing World Asteroid Day to raise awareness about the scientific value and potential risks of the asteroids. This event is held on the anniversary of the 1908 Tunguska event when a massive meteor explosion over Siberia had flattened over 80 million trees.
According to a Space.com report, the Virtual Telescope Project will be hosting a free livestream of near-Earth asteroids beginning at 5 pm EDT on June 30 to mark the occasion. Viewers can tune in via their official YouTube channel. Astronomers will also be discussing the characteristics of asteroids and the ongoing efforts to defend Earth from possible future impacts. Why do asteroids matter?
Earth has been struck by asteroids multiple times through the years. Some impacts, like the Chicxulub impactor, led to mass extinction events including that of the dinosaurs. The Space.com report further cited NASA's Center for Near-Earth Object Studies stating that over 30,000 near-Earth objects (NEOs) have been identified. Fortunately, no major asteroid poses a risk of colliding with Earth in the next century. How are NASA and global partners working to prevent asteroid threats?
According to the report, every year, global space agencies like NASA and the European Space Agency (ESA) participate in the Planetary Defence Conference, where they simulate asteroid impact scenarios and refine response strategies.
In 2022, NASA successfully conducted the Double Asteroid Redirection Test (DART) by intentionally crashing a spacecraft into Dimorphos, a moonlet of asteroid Didymos, The NASA intended to test whether a collision could alter its trajectory and the test confirmed kinetic impact was a viable method for planetary defense.
ESA's Hera mission will be revisiting the Didymos system in December 2026 to study the aftermath of the DART impact.
Meanwhile, efforts to detect potentially hazardous asteroids are ramping up with the introduction of the Vera Rubin Observatory in Chile. During initial scans, the observatory detected over 2,100 new near-Earth objects within days.
Željko Ivezić, deputy director of Rubin's Legacy Survey of Space and Time, was quoted as saying that two centuries' worth of effort can be outdone in just a couple of years.
The observatory is expected to discover up to five million new asteroids in the coming years, revolutionising our ability to monitor space threats. FAQs: 1. What is World Asteroid Day?
World Asteroid Day is a UN-backed annual event held on June 30 to raise awareness about asteroids and space safety. 2. How can I watch the asteroid livestream?
The Virtual Telescope Project will stream it live on their YouTube channel starting at 5 pm EDT on June 30. 3. Is Earth at risk from asteroids?
According to NASA, no large asteroid is projected to hit Earth in the next 100 years. 4. What is the DART mission?
NASA's DART mission tested whether crashing a spacecraft into an asteroid could deflect its path. It succeeded in altering Dimorphos's orbit.

Nasa to launch four astronauts just 16 days after returning India's Shubhanshu Shukla

Just sixteen days after the safe return of astronauts from the Axiom-4 mission, which included Indian astronaut Group Captain Shubhanshu Shukla , NASA is preparing for yet another journey to the International Space Station (ISS).On July 31, the space agency will launch the SpaceX Crew-11 mission, continuing its rapid pace of human spaceflight under the Commercial Crew launch is scheduled for 9:39pm IST from Launch Complex 39A at Kennedy Space Center in The SpaceX Dragon spacecraft will carry a four-member international crew: NASA astronauts Zena Cardman and Mike Fincke, JAXA astronaut Kimiya Yui from Japan, and Roscosmos cosmonaut Oleg Platonov from spacecraft is expected to dock with the ISS around on August mission is the 11th crew rotation flight to the ISS and the 12th human spaceflight using SpaceX's Dragon spacecraft since 2020. It underscores not only NASA's commitment to continuous human presence in space but also the strength of international aboard the ISS, the crew will participate in a series of cutting-edge scientific experiments, including studies on the effects of microgravity on the human body, biological systems, and advanced experiments contribute to both space exploration goals and practical technologies back on launch follows the successful return of the Axiom-4 mission on July 15, which was historic for India due to ISRO's involvement and astronaut Shubhanshu Shukla's participation. That mission marked a major milestone in India's expanding role in space Crew-11 prepares for launch, the world is once again reminded that the future of space isn't about one nation, it's about shared missions, global teamwork, and the united pursuit of knowledge beyond Earth.- EndsMust Watch

India has to triple its satellites in orbit by 2040: ISRO chief

Hyderabad, Jul 26 (PTI) ISRO Chairman V Narayanan on Friday said that India has to nearly triple its number of satellites in space, from the current 55, within the next three years. Delivering 'The GP Birla Memorial Lecture on Indian Space Programme – Accomplishments, Challenges and Future Perspectives', Narayanan said by 2040 India would be on par with any other nation in terms of space technology, application area, and infrastructure. He also said as many as 12 launch vehicle missions are planned by the ISRO this year. The upcoming mission, NASA-ISRO Synthetic Aperture Radar (NISAR) scheduled to be launched by India's GSLV F16 on July 30. 'Now we are working on building our own space station. We are going to have our own Chandrayan landing. Right now, 55 satellites are in orbit serving the common man in this country. And in another three years, this number has to become almost three times. The requirement is huge. The demand is so much that we have to build satellites. We are working towards that," he said. Later, talking to reporters, he said that in 2035 India will build a full space station, and the first module will be placed in orbit in 2028. view comments First Published: July 25, 2025, 13:45 IST Disclaimer: Comments reflect users' views, not News18's.

Will the whole world go dark on August 2? Here's the truth

Amid a flurry of viral posts and breathless headlines circulating across social media, many have been left wondering: Will the world experience a dramatic darkening on August 2, 2025, due to a total solar eclipse?The simple answer is reality, astronomers confirm there is no solar eclipse slated for August 2 this year. The true event generating all the excitement will not occur until August 2, Origins of the MisinformationThe rumors seem to have gained traction in online forums and instant messaging forwards, with phrases like "the Earth will be plunged into six minutes of darkness" attaching to the wrong posts even claim a once-in-a-century event will unfold in 2025, sending schools and skywatchers into a frenzy of false records from NASA and reputable observatories definitively state there will be no solar eclipse, total or partial, on August 2, the much-anticipated total solar eclipse is scheduled for August 2, 2027, when the Moon's shadow will sweep across parts of Europe, North Africa, and the Middle East, offering a rare celestial spectacle not seen in Really Happening in 2027On August 2, 2027, the Moon will move between the Earth and Sun, briefly turning day into night along a 'path of totality' stretching from southern Spain across North Africa and into the Middle eclipse will last for more than six minutes in some regions, making it one of the longest total solar eclipses of the 21st century, a phenomenon scientists and eclipse chasers are eagerly outside the path of totality, including much of Europe, Africa, and Western Asia, will witness a partial eclipse, while the vast majority of Earth's surface, including all of North America and most of Asia and Australia, will see no unusual darkening at Fact from FictionNo total solar eclipse will take place on August 2, 2025; claims to the contrary are 'six minutes of darkness' event will happen on August 2, 2027, but only within a narrow geographic corridor. The rest of the world will not notice any change in a vivid example of how online buzz can distort the facts, but skywatchers should keep their calendars marked for 2027. Until then, there will be no daytime darkness for the planet this August.- EndsMust Watch
