We can only wait for the destruction. Then the asteroid reaches the upper levels of the atmosphere. In few seconds that huge rock touches down. Destruction much worse than hundreds of atomic bombs begins.
As the rock digs into the...

Our house is located near fields and a small forest and the amount of artificial light here is smaller than in the center of our city. Even though we have less artificial lights, I consider myself living in a city. Based on this I am observing...

I hope this helps you to find the stars you are interested in. Notice that ...

Because of this a number of small "ghost" eruptions can be seen after the eruption. According to scientists, observations of these ghost eruptions could provide a new way to measure the masses and rotat...

Yes, that's right, but I did not mention that I am also reading Finnish astronomy magazine and watching astronomy movies in the Internet. This is a great way to spend Sunday mornings while others are still sleeping. We have...

Triangulum is located close to the famous Andromeda galaxy and it is quite easy to identify due to its clear shape. Ancient people used to call Triangulum as Sicilia, because according to Roman myth Ceres asked Jupiter to locate Sicily Island to the sky.
The brightest star in Triangulum constellation i...
