YR4 became the highest-rated asteroid predicted to strike Earth, and although predictions for impact have lowered, not enough is being done to track it, says local astronomer.

Astronomers believe thousands of large undiscovered asteroids, that could cause regional damage, may be in space.

Could a giant planet between Mars and Jupiter have doomed Earth? A new study suggests that small changes would have been manageable, but a massive super-Earth could have made our planet uninhabitable — offering clues about where life might (or might not) exist beyond our solar system.

Once, a very long time ago, a massive asteroid hit the Earth and wiped out the dinosaurs. In addition to functionally restarting land-based life on our planet and setting the stage for humans to eventually become the dominant species, that asteroid made us extremely aware of one thing—we are at risk.

Lucy is preparing for a close encounter with the asteroid Donaldjohanson, a key milestone before its groundbreaking journey to the Jupiter Trojans. This flyby serves as a crucial test of its optical navigation system,

Other “harbingers of doom” in 2025 will include two ‘blood moons,’ a potential fire in the northern sky and a sudden supernova.

The 2024 YR4 asteroid, which is nearly the size of a football field, now has roughly a 0.004% chance of hitting Earth in about eight years, according to the space agency's latest calculations. The Center for Near-Earth Object Studies previously projected a 3% chance of the asteroid striking our planet before lowering the chance to 0.28% last week.

NASA has significantly lowered the risk of asteroid 2024 YR4 hitting the Earth in 2032 through recent calculations. The moon however, may not be in the clear.

NASA is tracking a house-sized asteroid set to whiz past Earth tomorrow at a thundering 29,304 miles per hour. The space rock—named "2025 DJ22"—is estimated by NASA's Jet Propulsion Laboratory to be approximately 47 feet across, making it about the size of a house.

For a few days in mid-February, headlines around the world buzzed about the potential for an asteroid to hit the Earth in 2023—specifically, asteroid 2024 YR4. The chance of this impact rose to a high of 3.1 percent on Feb. 18. As a planetary geologist ...
