World Asteroid Day 2025 is upon us! Here is how one can have a good time the occasion by livestreaming real-time views of near-Earth asteroids from the consolation of your property.
June 30 is the tenth anniversary of World Asteroid Day, an annual United Nations-backed occasion whereby companions increase consciousness of asteroids, their scientific worth and the way humanity is working to mitigate the dangers posed by these wandering photo voltaic system our bodies. The date coincides with the anniversary of the 1908 Tunguska occasion, which noticed a big meteor detonate over Siberia, flattening thousands and thousands of timber and triggering widespread forest fires.
The Virtual Telescope Program has announced a livestream to mark World Asteroid Day on June 30, which is able to characteristic real-time views of near-Earth asteroids whereas discussing the traits and affect dangers posed by the enigmatic chunks of historic particles. The stream will likely be hosted on the Virtual Telescope Project’s YouTube channel beginning at 5 p.m. EDT (2100 GMT) on June 30 and will likely be free to look at.
Our planet bears the scars of numerous historic asteroid strikes, the biggest of which — such as the Chicxulub impactor — triggered the extinction of numerous species, irrevocably altering the evolutionary trajectory of life on Earth.
Fortunately, such occasions are exceedingly uncommon. Of the effectively over 30,000 near-Earth objects which were found and tracked to this point, no giant asteroid able to inflicting wide-spread destruction is anticipated to strike our planet within the subsequent 100 years, according to NASA’s Center for Near Earth Object Studies.
How NASA and its companions are tackling the asteroid menace
Defending the planet from an impending asteroid strike might as soon as as soon as have been the stuff of Hollywood sci-fi films, however current many years have seen the worldwide neighborhood take tangible steps in the direction of getting ready for a possible asteroid collision.
A Planetary Defense Conference is held annually during which NASA, ESA and its companions work to forestall and react to a hypothetical asteroid affect. Every successive train has highlighted recent challenges surrounding response methods, starting from the velocity at which missions could possibly be designed and launched to greatest collect intelligence and talk with most of the people.
After all preparations have additionally prolonged far past tabletop simulations. September 2022 noticed NASA’s Double Asteroid Redirection Test (DART) made historical past when it slammed into the floor of the 160-meter-wide (252 ft) moonlet Dimorphos, which varieties a binary pair with the bigger asteroid Didymos. The mission proved {that a} kinetic affect might considerably deflect the trajectory of a small photo voltaic system physique and so could also be a viable technique for defending Earth. The Didymos system is about to be visited by the European Space Agency’s Hera mission in December 2026, which is able to observe the aftermath of the affect.
A brand new asteroid hunter enters the fray
On prime of that, telescopic eyes are continuously scanning the evening sky for proof of doubtless hazardous close to Earth objects shifting in opposition to the starfield past. The approaching years will see these efforts considerably bolstered by the highly effective telescopic eye of the Vera Rubin observatory.
The Rubin Observatory’s primary mission is to scan the whole lot of the southern hemisphere night sky from its vantage level atop mount Cerro Pachon in Chile in a bid to make clear the mysterious drive often known as ‘darkish power’ and an invisible element of the universe known as ‘dark matter‘. Nonetheless, its preliminary observations have additionally highlighted its credentials as an asteroid hunter.

Wish to see asteroids within the evening sky? The Celestron NexStar 4SE is good for inexperienced persons wanting high quality, dependable and fast views of celestial objects. For a extra in-depth have a look at our Celestron NexStar 4SE review.
Over the course of only a few nights, astronomers had been in a position to identify 2,104 new near-Earth objects as they handed over the Rubin observatory’s area of view, with some astronomers estimating that the observatory might discover as much as 5 million extra over the approaching years.
“That is 5 instances greater than all of the astronomers on the earth found over the last 200 years because the discovery of the primary asteroid,” Željko Ivezić, Deputy Director of Rubin’s Legacy Survey of House and Time, mentioned throughout a press convention unveiling the observatory’s first photos on June 23. “We will outdo two centuries of effort in simply a few years.”
