Comet Explodes Over Spain and Portugal: Everything We Know

What are comets?

Comets are celestial bodies that consist of ice, dust, and rocks. They revolve around the Sun on elliptical trajectories. As a comet approaches the sun, the ice in its core sublimates, or turns from a solid to a gas. This creates a coma, or cloud of gas and dust, around the nucleus. The solar wind then blows the coma away from the sun, forming a tail.

What causes comet explosions?

When a comet gets too close to the Sun, the heat can cause its nucleus to collapse. This can release large amounts of gas and dust, which can cause a spectacular explosion. The explosion seen over Spain and Portugal is thought to have been caused by a comet passing close to the Sun for the first time.

What are the consequences of a comet explosion?

Comet explosions can have a number of consequences for Earth. Dust and gas from the explosion could reflect sunlight, which could cool the Earth. An explosion can also release harmful chemicals into the atmosphere that can harm human health. However, comet explosions are relatively rare and usually do not pose a serious threat to Earth.

What do we still not know about comets?

There's still a lot we don't know about comets. Scientists are still working to understand their composition, formation, and behavior. They are also trying to determine what impact comets have on Earth.
