The year one hundred two thousand twenty-three. A giant meteorite the size of Pluto is approaching the Solar System. It flies straight to Earth. But as the meteorite crosses Saturn’s orbit, a swarm of miner probes approaches it. The scan revealed no minerals on the object, so the searches returned with nothing.
Meanwhile, the Space Security Center in Alaska military personnel are setting up a laser. The Solar System witnesses a sudden flare and nothing remains of the dwarf-sized meteorite. Now, unless hydrogen miners on Jupiter post videos of another annihilation on social media… This is what the world will look like when humanity finally becomes a Type Two civilization on the Kardashev scale. We’ll have almost infinite energy reserves, the ability to prepare for interstellar flights, or to instantly destroy any threat. But will humanity really be safe? And what can ruin a Type Two civilization?

The odds of a ‘city-destroying’ asteroid hitting Earth in less than 10 years have risen.

Asteroid 2024 YR4 was found by NASA’s Asteroid Terrestrial-impact Last Alert System and it’s now at the top of NASA’s Sentry Risk Table and European Space Agency’s NEO (near Earth objects) impact Risk List.

Almost 2% chance for catastrophic impact in 7 years? What should we do?

A new climate modeling study published in the journal Science Advances by researchers from the IBS Center for Climate Physics (ICCP) at Pusan National University in South Korea presents a new scenario of how climate and life on our planet would change in response to a potential future strike of a medium-sized (~500 m) asteroid.

The solar system is full of objects with near-Earth orbits. Most of them do not pose any threat to Earth, but some of them have been identified as objects of interest with non-negligible collision probabilities. Among them is the asteroid Bennu with a diameter of about 500 m, which—according to recent studies—has an estimated chance of 1 in 2700 of colliding with Earth in September 2182. This is similar to the probability of flipping a coin 11 times in a row with the same outcome.

To determine the potential impacts of an asteroid strike on our climate system and on and plankton in the ocean, researchers from the ICCP set out to simulate an idealized collision scenario with a medium-sized asteroid using a state-of-the-art climate model.

Simulations of a potential impact by a hill-sized space rock event next century have revealed the rough ride humanity would be in for, hinting at what it’d take for us to survive such a catastrophe.

It’s been a long, long time since Earth has been smacked by a large asteroid, but that doesn’t mean we’re in the clear. Space is teeming with rocks, and many of those are blithely zipping around on trajectories that could bring them into violent contact with our planet.

One of those is asteroid Bennu, the recent lucky target of an asteroid sample collection mission. In a mere 157 years – September of 2,182 CE, to be precise – it has a chance of colliding with Earth.

Astronomers have also calculated a predicted impact zone that stretches from South America across the Atlantic Ocean to sub-Saharan Africa.

The asteroid has the potential to cause significant damage, especially if it lands in a densely populated area like a major city due to it being the size of another space rock that hit Earth in 1908 with a blast equivalent to detonating 50 million tons of TNT.

Though estimates suggest a very small increase in the likelihood of impact, astronomer and professor of planetary sciences at the Massachusetts Institute of Technology (MIT) Richard P Binzel told DailyMail.com that it is nothing to worry about.

Curtin University researchers have gained an unprecedented glimpse into the early history of our solar system through some of the most well-preserved asteroid samples ever collected, potentially transforming our understanding of planetary formation and the origins of life.

Experts from Curtin’s School of Earth and Planetary Sciences were selected to be among the first in the world to inspect samples collected during NASA’s seven-year, OSIRIS-REx mission to the ancient asteroid Bennu.

Asteroid Bennu is thought to be made of rubble fragments from a 4.5-billion-year-old parent body, containing materials that originated beyond Saturn, which was destroyed long ago in a collision with another object.

A colossal explosion in the sky, unleashing energy hundreds of times greater than the Hiroshima bomb. A blinding flash nearly as bright as the sun. Shockwaves powerful enough to flatten everything for miles.

It may sound apocalyptic, but a newly detected asteroid nearly the size of a football field now has a greater than one percent chance of colliding with Earth in about eight years.

Such an impact has the potential for city-level devastation, depending on where it strikes.

Researchers at MIT have developed a method to detect small asteroids in the main asteroid belt, significantly improving our ability to spot objects as little as 10 meters across.

This new technique, which identified 138 space rocks ranging from bus-to stadium-sized, allows for earlier detection and better tracking of potential near-Earth objects, enhancing planetary defense. The approach, using data from telescopes initially aimed at exoplanets, has uncovered over a hundred new asteroids, with implications for understanding asteroid origins and collision processes.
