On December 22, 2032, a sixty-metre-wide asteroid may strike the Moon. If this happens, it will not only produce a visible flash, easily spotted from Earth, but will likely be followed by periodic ...

An asteroid the size of a building could collide with the Moon in 2032 and generate a flash visible from Earth.

A famously resilient bacterium may be tough enough to survive one of the most violent events imaginable on Mars. In ...

The extremophile bacterium Deinococcus radiodurans can survive the pressures developed during ejection from Mars as a result of massive asteroid impact. According to the authors, microorganisms can ...

Space agencies maintain that global cooperation and sustained investment are vital to planetary defence. While the DART ...

Estimating a mass for a potentially hazardous asteroid (PHA) is perhaps the single most important thing to understand about ...

Asteroid 2024 YR4, discovered in late December 2024, is about 60 meters in diameter. Early calculations briefly suggested it carried an unusually high risk of hitting Earth, drawing global attention, ...

The extremophile bacterium Deinococcus radiodurans can survive the pressures developed during ejection from Mars as a result of massive asteroid ...

"For asteroids of the size scale relevant to planetary defense (i.e., ∼50-500 m), the mass can only be directly measured ...

James Webb Space Telescope (JWST) will provide insights far more precisely than ground telescopes can manage now, as the rock ...

NASA experts warned that human beings are vulnerable to thousands of hidden “city-killer” asteroids. A new space telescope may improve detection, but we currently lack tools to stop a threat.

Imagine a rock the size of a football stadium hurtling through space at thousands of miles per hour, heading straight for a major city, and we have no way to stop it. NASA has just issued a sobering ...
