On June 17, in the year 2 B.C.E, a significant planetary conjunction occurred involving Venus and Jupiter. From Earth’s perspective, these two bright planets appeared to draw so close that they ...

The James Webb Space Telescope has taken another look at the potential "city-killer" asteroid 2024 YR4 and found its chances of hitting the moon in December 2032 have increased to 4.3%.

The asteroid, about a third of a mile wide at its equator, poses no immediate threat to our planet. But hundreds of years from now, there is a small chance that Bennu could slam into Earth.

An enormous asteroid—big enough to leave a six-mile-wide crater and darken the world with dust if it hit Earth—will harmlessly zip by our planet on April 29. The object, called 1998 OR2, is at ...

Another asteroid, Aphophis, received some attention after its discovery in 2004, and the 2.7% chance it held of hitting Earth in 2029. Additional observations showed that, while it will make a ...

According to NASA, the Webb data refined the asteroid's projected location on December 22, 2032, by nearly 20%. This revised number has thus nudged the probability of a lunar collision from 3.8% ...

The 2024 YR4 asteroid, which once registered a possibility of hitting Earth, now has a 4.3% chance of hitting the moon in 2032. The latest observations utilized NASA’s James Webb Space Telescope.

NASA confirmed the discoveries this spring—calling them the first clearly unstable Venus–Earth co‑orbitals —and placed them on its watch list. These rocks aren’t headed our way tomorrow, yet the find ...
