No one knows for sure what caused the Tunguska event in Siberia. Here are some theories about what might have been the cause.

- La Huella OVNI looks at the Tunguska event.
- This is still a puzzle for scientists.
- Some people think it was a big rock from space, others think it was gas, and some think it might have been aliens.
A big space event happened in Tunguska, a faraway place in Siberia, on June 30, 1908.
That day, a big explosion shook the area and caused a lot of damage. People are still trying to figure out why it happened.
Tunguska is a big, cold place in Russia with not many people. A big event changed this place forever.
On the morning of June 30, 1908, people heard a loud noise and saw a bright light.
The Tunguska Explosion

Soon after, this force destroyed houses, broke windows, and ruined part of a small town.
The explosion was heard and felt very far away, and the light was seen in the sky in other countries for many months.
People think the strong wave from the explosion went around the Earth two times.
Many ideas came up about why this happened, and a lot of people talked about it.
What was it?

Ideas include a big rock from space, gas from the Earth blowing up, or maybe even a spaceship crashing.
Some think that the Russian leaders found alien clues there, but others don’t believe this.
People have many different thoughts about this Tunguska event.
For over a hundred years, scientists and enthusiasts have tried to clarify the incident. Over 50 theories have been proposed, with some being more accepted than others.
What caused the Tunguska event?

Many believe a space rock caused the explosion. But, others think gas from inside the Earth might have blown up.
In the past few years, more scientists believe a space rock might be the cause.
In 1921, a man named Leonid Kulik went there to study what happened.
He found out the damage looked different, maybe like two explosions happened, not just one.
Asteroid Day

Scientists keep studying Tunguska with new tools.
New studies think maybe the space rock just touched the sky and didn’t hit the ground. This is because the sky was very bright after it happened.
Because of new studies, people are now more aware of space rocks that might hit Earth.
The UN made June 30 «Asteroid Day» to help people know more about these space rocks.
