Imagine our planet as a cozy home. From space, things can happen that make our home uncomfortable or even unlivable. For example, our Sun, which gives us light and warmth, could get

Global Catastrophic Risk Analyst

Cosmic events present distinct, albeit low-probability, existential threats. A direct impact from a large asteroid or comet could trigger immediate, extinction-level events through widespread atmospheric dust, tsunamis, and

Planetary Defense Expert

From a planetary defense perspective, external cosmic threats represent a paramount danger to Earth's habitability. Direct impacts from asteroids or comets could trigger global devastation, leading to impact winters, tsunamis,

Geophysicist

Cosmic events pose significant threats through their direct physical impact on Earth's systems. Large bolide impacts, for instance, can induce widespread seismic activity, generate massive tsunamis, and inject vast quantities

Astrophysicist

Earth's habitability is fundamentally contingent upon the stability of its celestial mechanics and the consistent energy output from its parent star. Over cosmic timescales, the Sun's predictable stellar evolution poses the ultimate threat

Points of agreement

• Cosmic events, particularly impacts from celestial bodies (like asteroids or comets), pose a significant threat to Earth's habitability.
• The consequences of these cosmic events can
