Earth is continuously at risk from potential hazards in space, and perhaps the most dreaded are near-Earth asteroids—space objects with orbits bringing them close to the planet in threatening proximity. While most pass harmlessly by, each near-flyby serves as a sobering reminder of Earth's exposure. A near-Earth asteroid, namely asteroid 2025 HY2 , has just caught significant attention from scientists and space agencies all over the world.Its upcoming flyby calls to mind the ongoing need for caution, improved detection capabilities, and global cooperation to protect our world from potentially one day being a disastrous impact event.Asteroid 2025 HY2 ought to be near its Earth-closing point on May 7, 2025, at 12:49 PM IST (07:19 UTC). It will be flying by at a remarkable velocity of approximately 48,904 kilometres per hour (approximately 30,389 miles per hour) when nearest to flyby.Though close and fast, the asteroid will fly by Earth by a mere 6.8 million kilometres (4.2 million miles). Though this sounds like a huge distance, by cosmic standards, it's a close call.Asteroid 2025 HY2 is an Apollo-class asteroid, a class of asteroids with orbits that cross Earth. They circle the Sun but cross Earth's orbit, and as such, they are of particular interest to planetary defense research.Apollo-class asteroids are some of the most tightly monitored near-Earth objects (NEOs). Even though nothing is threatened in the near term, orbits are adjusted by the action of gravity or solar radiation pressure over geological time scales and formerly harmless rocks in space can become threats.Space agencies like NASA and the European Space Agency (ESA), in association with global observatories, work around the clock to monitor and evaluate the threats from these objects. The Center for Near-Earth Object Studies (CNEOS) and the Minor Planet Center gather and analyze information from a global network of professional and amateur astronomers.Through this collaborative effort, scientists can accurately predict asteroid orbits, enhance orbital simulations, and provide warning in advance of predicted collisions. But despite all these advances, the majority of small- to medium-sized asteroids are not found until near Earth.While 2025 HY2 is not a "potentially hazardous asteroid" (a designation reserved for those that are larger than 140 meters in diameter), it is big enough-about 120 feet (37 meters) in diameter, the size of a Boeing 737.If it were to enter the Earth's atmosphere, the effect would be catastrophic. To give an example, the Chelyabinsk meteor that detonated in the air over Russia in 2013 was only 59 feet (18 meters) in diameter. But it hurt more than 1,500 people, broke thousands of buildings, and caused indiscriminate panic from a shockwave.A 2025 HY2 crash that is twice the magnitude of the 2013 crash can wipe out city blocks a few kilometres from ground zero.Asteroid 2025 HY2 is not the threat this time, but the close flyby is a hair-raising reminder. There are thousands of such asteroids that are yet to be discovered in our solar system, and the warning margin can be very narrow.This advancement of early warning systems, planetary defense missions, and even technology to deflect an asteroid is global. NASA's DART mission-Double Asteroid Redirection Test, for example, was a historic benchmark demonstrating our ability to push the asteroid off its course.Yet, as these objects make their way quietly towards our planet, disaster lurks around the corner. Asteroid 2025 HY2 is merely the newest in a never-ending rotation of reminders that defending the world isn't science fiction—it's real-life insurance against extinction.

Did Kamchatka Earthquake Trigger First Volcano Eruption In 600 Years? What Russian Team Says
Last Updated: 'This is the first historically confirmed eruption of Krasheninnikov Volcano in 600 years,' RIA cited Olga Girina, head of the Kamchatka Volcanic Eruption Response Team, as saying The overnight eruption of the Krasheninnikov Volcano in Kamchatka, its first in 600 years, may be connected to the huge earthquake that rocked Russia's Far East last week, Russia's RIA state news agency and scientists reported on Sunday. 'This is the first historically confirmed eruption of Krasheninnikov Volcano in 600 years," RIA cited Olga Girina, head of the Kamchatka Volcanic Eruption Response Team, as saying. She added that the eruption may be connected to the earthquake on Wednesday that triggered tsunami warnings as far away as French Polynesia and Chile, and was followed by an eruption of Klyuchevskoy, the most active volcano on the Kamchatka Peninsula, according to a CNN report. WATCH: Incredible footage of the FIRST RECORDED ERUPTION of Krasheninnikov volcano in Kamchatka, wouldn't be a surprise to me if it was triggered by the megathrust M8.8 earthquake a few days ago. Krasheninnikov volcano began its FIRST RECORDED eruption at 16:50 UTC… — Volcaholic 🌋 (@volcaholic1) August 3, 2025 On the Telegram channel of the Institute of Volcanology and Seismology, Girina said that Krasheninnikov's last lava effusion took place in 1463 – plus or minus 40 years – and no eruption has been known since. The Kamchatka branch of Russia's ministry for emergency services said that an ash plume rising up to 6,000 meters (3.7 miles) has been recorded following the volcano's eruption. The volcano itself stands at 1,856 meters. 'The ash cloud has drifted eastward, toward the Pacific Ocean. There are no populated areas along its path," the ministry said on Telegram. The eruption of the volcano has been assigned an orange aviation code, indicating a heightened risk to aircraft, the ministry said. All about Kamchatka earthquake One of the world's strongest earthquakes struck Russia's Far East last week, an 8.8-magnitude temblor that caused small tsunami waves in Japan and Alaska and prompted warnings for Hawaii, North and Central America and Pacific islands south toward New Zealand. Ports on the Kamchatka Peninsula in Russia near the quake's epicentre flooded as residents fled inland. Cars jammed streets and highways in Honolulu hours before tsunami waves were expected. Waves less than a foot above tide levels were observed in the Alaskan communities of Amchitka and Adak, said Dave Snider, tsunami warning coordinator with the National Tsunami Warning Center in Alaska. White waves washed up to the shoreline on Japan's Hokkaido in the north and Ibaraki and Chiba, just northeast of Tokyo, in footage aired on Japan's NHK public television. A tsunami of 50 centimeters (1.6 feet) was detected at the Ishinomaki port in northern Japan, according to the Japan Meteorological Agency. That was the highest measurement so far among several locations around northern Japan. But higher waves were still arriving, said Shiji Kiyomoto, an earthquake and tsunami response official at JMA. The earthquake's epicentre was the Kamchatka Peninsula, which is part of the Pacific Ring of Fire.

Moon tonight shines at 69 percent brightness as Waxing Gibbous phase illuminates the sky
TIL Creatives The Moon is in its Waxing Gibbous phase tonight, with 69 percent of its surface illuminated, offering stunning views of craters and lunar seas as it moves closer to next week's full moon Skywatchers across the United States can expect a dazzling display in tonight's sky as the Moon enters a Waxing Gibbous phase, lighting up 69 percent of its surface, according to NASA's Daily Moon Observation. The glowing lunar disk is steadily building toward the next full moon, expected on August 9. Moon tonight(August 3) marks day 10 of the lunar cycle, part of the Moon's ongoing 29.5-day journey around Earth. These cycles, new moon to full moon and back again, are created by the Sun's light reflecting off different portions of the Moon's surface as it orbits Earth. It's a rhythm that has guided humanity for millennia. The Waxing Gibbous moon is more than halfway lit but not yet full. As it rises in the eastern sky just before sunset and sets shortly after midnight, it creates an excellent opportunity for both casual stargazers and astronomy enthusiasts. Even without any equipment, you can spot major features like the Copernicus Crater, Mare Fecunditatis, and Mare Crisium. Binoculars will reveal the Alphonsus Crater, Posidonius Crater, and Mare Frigoris. Those with telescopes can explore the Rima Ariadaeus, the Descartes Highlands, and the Fra Mauro Highlands, where Apollo 14 once landed. According to NASA, there are eight primary phases of the Moon: New Moon, Waxing Crescent, First Quarter, Waxing Gibbous (tonight's phase), Full Moon, Waning Gibbous, Last Quarter, and Waning always see the same side of the Moon, but the amount illuminated changes as it orbits Earth. That shifting glow creates the lunar phases we observe each night.
