A meteor emitted a strong light before exploding in the skies over Norway and falling into a hard-to-reach forested region, according to local investigators and experts in objects coming from space. Residents reported to authorities "a strong explosive sound" and "strong draft".

The episode, which took place on the 25th, marks the third most notable incident involving an object from space entering Earth this year — in March, a meteor crossed the skies over England, Wales and northern France, and another passed through Vermont, USA, in the same month.

According to images recorded by several residents, the meteor that lit up Norway's night sky is "strangely large" and left a trail of flashes of light around 1:60 am, before falling into the region known as "Finnemarka" — just a little more XNUMX kilometers (km) from the city of Oslo — with dense forests and difficult access. Because of this, experts estimate that the recovery of its fragments — the meteorites — may take up to 10 years.

According to Morten Bilet, a meteorite collector and researcher at the Norwegian Meteor Network (NMN), the object reached an average speed of 72 thousand kilometers per hour (km/h), and due to its large size and very high speed, it left a trail of light intense enough to illuminate the night for somewhere between 3 and 5 seconds.

Bilet told the Reuters news agency that the meteor had arrived on Earth after being diverted from its original course — it was traveling between Mars e Jupiter, when he hit an asteroid in the belt, but could not offer more details of his “visit”: “with an object of this size, it is almost impossible to have a detailed view of everything”, said the expert. “It would be easier if he had a steeper trajectory. We still don't know if it was a rocky meteor or an iron one.”

The difference between stone (rocky) and iron meteors lies in their point of origin: the first type is usually "born" as a piece of the crust of a planet or asteroid, which has broken off from the main body. Iron meteors, on the other hand, have their nature initiated from the core of these same objects. In the case of the Oslo object, it can be classified as “bolide” — the name given to objects with a brightness equal to or greater than Venus, and are capable of completely illuminating the night sky.

This type of meteor emits all that light thanks to two factors: size and speed. Typically, bolides are larger than average, and travel at a speed many times greater than that of sound. These two factors contributed to the generation of immense friction at the entrance to our atmosphere, “burning” the object to the point that it exploded in the sky. Thousands of such episodes occur every day, but we usually don't notice them because they are too small to be seen with the naked eye, or because larger objects fall into uninhabited regions.
