Mars had an ocean, sandy beaches 3 billion years ago, scientists say

Evidence suggests Mars once had an ancient ocean, with data from China's Zhurong rover revealing coastal deposits beneath the surface.

An illustration shows a hypothetical picture of Mars 3.6 billion years ago when an ocean may have covered nearly half the planet, released February 24, 2025. The blue areas show the depth of the ocean filled to the shoreline level of the ancient, now-gone sea, dubbed Deuteronilus. The orange star represents the landing site of the Chinese rover Zhurong and the yellow star is the site of NASA's Perseverance rover, which landed a few months before Zhurong.(REUTERS)

Asteroid 2024 YR4 is about half the width of a football field and will pass very close to Earth on December 22, 2032, coming within approximately 106,200 km

NASA's earlier analysis indicated a slightly higher probability of over 1 per cent, meaning there is roughly a 99 per cent chance that Asteroid 2024 YR4 will miss Earth. (Pic used for representation)(AP)
