The Mars Occultation In Dawn

The Mars Occultation In Dawn

On the Slovakian morning of 8th December 2022, planet Mars appeared in opposition to the Sun, making the opportunity to observe it the whole night from dusk until dawn about twice brighter than Sirius, the brightest star in the sky. But not just that. Just in the time of the opposition, at 5:36 UT, the…

The River over the Desert

Gems of the Atacama Desert

Spending time in the San Pedro de Atacama region this April brought me and my friends also to the middle of a hidden valley not far from the famous Valle de la Luna. Since the salty desert surroundings are just so large, there is still so much to discover. This is another example. I found…

Luckily, the weather is very favorable and Moon doesn’t shine when radiant rises, so I took the chance to capture this composite image. Foreground was taken on May 3rd while meteors were…

Volcanic Sky over the Atacama Desert

In this shot, taken from San Pedro de Atacama (Chile) on April 18th, 2022, a like-Martian night sky appears just after dusk. While the majestic dark sky with prominent constellations of Orion, Vela, or Southern Cross can be found along the Milky Way, both directions over the western and eastern horizons shine very redly. This…

Aurora from Czech Republic on 14 March 2022

Aurora Borealis from the Czech Republic

The Czech Republic lies on latitude 50N, away from the magnetic pole, which makes it one of the countries where the Northern Lights are very rare. However, not impossible. Statistically, there can be spotted 10-15 auroras per one solar cycle (~11 years), of course, especially around the solar maximum. The upcoming one, solar cycle 25,…
