Do you think asteroids will ever hit the Earth? After all, there are many instances of asteroids smashing into Earth, or exploding in its atmosphere, a long time ago in the past and very much so recently too - just recall the recent Chelyabinsk asteroid.
However, at the moment, NASA says that there are no known impact threats from asteroids. Having said that, tiny meteorites break into Earth's atmosphere all the time and hit the ground.
One just hit a woman in the chest while she was having coffee in her balcony! It was small and had hit the roof before falling on her.
Dr. Kelly Fast, planetary defense expert and a manager in NASA's Planetary Defense Coordination Office explains. Dr. Fast said, “Asteroids have hit Earth over the course of its history, and it will happen again.”
According to the report by NASA, space dust, meteoroids, and even small asteroids hit Earth all the time and they create the meteors or “shooting stars” that you see as they disintegrate in the atmosphere. But impacts of asteroids that affect the surface are much rarer and happen on time scales of hundreds to thousands to millions of years.
However, there are asteroids that escape detection and the threat stems from them. For instance, just a few weeks ago, an asteroid passed threateningly close to Earth and no one even knew about it till it had passed our planet.
The only solution available is the early detection of asteroids that pose a threat to Earth is crucial. This will provide sufficient warning and help in taking measures against it if needed.
Fortunately, larger asteroids are more readily detectable, and the number of such asteroids in our solar system is relatively smaller, which is reassuring.
At the moment, NASA has experimented with its Double Asteroid Redirection Test (DART) and successfully managed to change the orbit of an asteroid in motion. Asteroid Didymos and its moonlet Dimorphos were targeted by NASA. A spacecraft was crashed into the latter and this altered their course appreciably. However, that required an immense amount of time and preparation, something that may not be available when the next asteroid catches astronomers by surprise.

What's a government space agency like the National Aeronautics and Space Administration supposed to do if private companies like SpaceX get all the spacefaring glory? One option is to double down on investments in leading-edge advancements that may not pay off for years. Super-fast and maneuverable nuclear-powered rocket engines are one such technology. Last month, NASA, partnering with the Department of Defense, gave Lockheed Martin Corp. nearly $500 million to build and test one by 2027.
Starfield's hype handle cranks ever-more furiously in the run-up to its September release, and Bethesda has now fired out a scattershot volley of fresh details, courtesy of a new Discord Q&A.
Destiny 2’s next expansion, The Final Shape, is set to conclude the years-long story of the space-based MMO looter shooter. Bungie has released new details on its upcoming Destiny 2 Showcase, which will give players their first look at what to expect from the epic final chapter of the Light and Darkness storyline and what kind of content they can look forward to in Season 22, and other announcements related to the game.
launched the firstfor its cloud gaming services. The streaming company launched Netflix Games in 2021 and released an official Netflix Game Controller iOS app last week. While the app’s release foreshadowed the next step in Netflix’s cloud gaming ambitions, the beta’s launch is still a big surprise.
Cale Makar gets the call.
As the Sun moves towards the solar maximum gradually, scientists are worrying about a once in a century solar storm that can impact Earth, and humanity, severely. We are now experiencing the most active sun so far and it is generating massive solar storms frequently. The peak of solar activities happens every 11 years when the sun reaches the solar maximum. Normally, these solar storms do not severely impact the Earth, but, occasionally, they get so intense that they can generate strong geomagnetic storms that affect all the electrical infrastructure that humanity has created including the power grid and the satellites. NASA believes that if such a solar storm occurs, it could put the safety and livelihoods of people at risk. Now, it is being feared that such a massive solar storm can happen over the next few years.
Happy Friday, Polygon readers. This week is an exciting one in new movies to watch at home: Spider-Man: Across the Spider-Verse, the thrilling sequel to 2018 Oscar-winning smash hit Into the Spider-Verse and one of the best movies of 2023, finally drops digitally and is available to purchase online.
There is a ton of hype built up around the next big RPG from the talented folks at Bethesda. This is also their first new RPG in several years and is the first game developed under the Xbox umbrella. So there’s quite a bit of pressure to deliver. However, if you’re planning to play this game on the PC platform, then you might want to make sure your PC can handle it. Fortunately, if you’re in the market for upgrading, then you might find these two components from AMD enticing to check out.
A new Call of Duty: Modern Warfare 3 trailer has introduced the return of a major franchise villain.
The last 24 hours were quite frightening for the Earth, as major solar storm prediction models said that a highly energized cannibal CME could deliver a glancing blow to the Earth today, August 9. However, it never came, leading the scientists to believe that the CME narrowly escaped the planet. Investigations are still ongoing to see whether the CME could have been delayed. However, there is some bad news as well. In the early hours of August 8, another X1-class solar flare erupted and sparked a deep shortwave radio blackout over the Pacific Ocean. Concerns are now rising on whether it will also send another CME towards our planet.
Is the asteroid threat a mere figment of our imagination? Is the fear driven mostly by Hollywood movies like the Bruce Willis, Ben Affleck starrer Armageddon or the more recent Leonardo DiCaprio and Jennifer Lawrence-starrer Don't Look Up? Well, you should know that these asteroids can actually be a huge hazard for Earth. The chances of an asteroid crashing on Earth are slim, but it has happened before on a regular basis causing the extinction of many species, most famously, that of dinosaurs. Yes, we have all heard about the ending of the era of dinosaurs due to a massive asteroid that hit the Earth's surface. It happened 65 million years ago and even as recently as 2013, an asteroid exploded over a Russian city causing injury to nearly 1000 people.
