A nice Autumn day, surprisingly without clouds. Exactly this day the nature prepared for us a nice performance on the sky. Moon’s shadow covered a part of our sun. Did you have an opportunity to take some photos? Feel free to share, I’m curious 🙂 More info about the eclipse of sun and contact is here.

The Observatory and Planetarium of Brno is well known for their excellent programs for the public. Yesterday there was a large nanostructure where people could walk inside and learn new interesting knowledge, a large heliosphere with live comments of professional astronomers. The late evening was dedicated to the summer cinema – projecting if space-related films on the wall outside of the observa…

Jupiter – the largest planet in the Solar System is specific not only because of its size, but also because of its system of moons that reminds in a some way a “mini Solar System”. This planet is one of those that can be easily seen on the night sky. I am sure that you… […]

I received an interesting offer – AI online course by Stanford University. Maybe it would be useful also for you my friends. The planetary science and space technology uses this technology quite a lot. The course of Artificial Intelligence can be found below: Artificial Intelligence: Principles and Techniques Artificial Intelligence has emerged as an increasingly […]

I would like to share with you some beautiful photos of some of the planets of the Solar System that have been taken recently by the Hubble Space Telescope.

I took the photo of that obejct, after small zoom it looks interesting. 🤔 The image poblished in this post is stacked from 10 photos. Some interesting […]

In a couple of days will be launched by NASA the first mission to the Trojan asteroids – mission called LUCY. Are you ready to join this mission by watching its first seconds and minutes? Description to animation above: Jupiter’s Trojans (green) follow the giant planet (orange) on its orbit around the Sun. This animation […]
