On 26 September 2022, the Double Asteroid Redirection Test demonstrated the deflection of an asteroid. According to expert testimony in the United States Congress in 2013, NASA would require at least five years of preparation before a mission to intercept an asteroid could be launched. In June 2018, the US National Science and Technology Council warned that America is unprepared for an asteroid impact event, and has developed and released the " National Near-Earth Object Preparedness Strategy Action Plan" to better prepare. In April 2018, the B612 Foundation reported: "It's 100 percent certain we'll be hit, but we're not 100 percent certain when." Also in 2018, physicist Stephen Hawking considered in his final book Brief Answers to the Big Questions that an asteroid collision was the biggest threat to the planet. Impact events have been a plot and background element in science fiction. An extrasolar impact was observed in 2013, when a massive terrestrial planet impact was detected around the star ID8 in the star cluster NGC 2547 by NASA's Spitzer Space Telescope and confirmed by ground observations. ![]() The Comet Shoemaker–Levy 9 impact provided the first direct observation of an extraterrestrial collision of Solar System objects, when the comet broke apart and collided with Jupiter in July 1994. Its meteor is the largest recorded object to have encountered the Earth since the Tunguska event. The 2013 Chelyabinsk meteor event is the only known such incident in modern times to result in numerous injuries. One of the best-known recorded events in modern times was the Tunguska event, which occurred in Siberia, Russia, in 1908. Throughout recorded history, hundreds of Earth impacts (and exploding bolides) have been reported, with some occurrences causing deaths, injuries, property damage, or other significant localised consequences. The prehistoric Chicxulub impact, 66 million years ago, is believed to not only be the cause of the Cretaceous–Paleogene extinction event but acceleration of the evolution of mammals leading to their dominance and in turn, setting in place conditions for the eventual rise of humans. They have also been implicated in several mass extinctions. Impacts have been suggested as the origin of water on Earth. Impacts may have helped deliver the building blocks for life (the panspermia theory relies on this premise). Impact events also appear to have played a significant role in the evolutionary history of life. Major impact events have significantly shaped Earth's history, and have been implicated in the formation of the Earth–Moon system. Impact events appear to have played a significant role in the evolution of the Solar System since its formation. Impact craters and structures are dominant landforms on many of the Solar System's solid objects and present the strongest empirical evidence for their frequency and scale. When large objects impact terrestrial planets such as the Earth, there can be significant physical and biospheric consequences, though atmospheres mitigate many surface impacts through atmospheric entry. Impact events have physical consequences and have been found to regularly occur in planetary systems, though the most frequent involve asteroids, comets or meteoroids and have minimal effect. The movie started strong but that feeling was over very soon.A major impact event releases the energy of several million nuclear weapons detonating simultaneously when an asteroid of only a few kilometers in diameter collides with a larger body such as the Earth (image: artist's impression).Īn impact event is a collision between astronomical objects causing measurable effects. On the positive side, there were moments of sublime acting from Summer Bellessa (Naomi) and Michael Beach (Jonah). This was a very disappointing movie, felt really like a waste of time and even the dialogues made no sense. Starting with a fake exorcism, Naomi's extremely devout mother lecturing her about Jesus, Jonah and his "faith" etc. This was supposed to be a horror movie but to me it was more a half cooked bible sermon. Once the team reaches the impact point, they start to experience hallucinations that blur the lines between science and faith. They rent a boat owned by Davis (Eugene Byrd) and captained by a man named Jonah (Michael Beach). When a meteorite lands somewhere in The Bermuda Triangle and starts emitting strange signals they think they may have discovered what they were looking for. Naomi (Summer Bellessa) and her team are looking for proof of extraterrestrial life.
