The Day the Earth Smiled

Oradea, Romania. 

In this rare image taken on July 19, 2013, the wide-angle camera on NASA's Cassini spacecraft has captured Saturn's rings and our planet Earth and its moon in the same frame. 

The Earth, which is 1.44 billions kilometers away in this image, appears as a blue dot in center right; the Moon can be seen as a fainter protrusion off its right side.

Saturn, the master of rings

Saturn is the second-largest planet and the easiest to recognize because of the bright rings around its equator.

They consist of chunks of ice and rock, ranging from specks of dust to large icebergs.

My students tried to made glorious rings around the beautiful Saturn.

The Sun

The Sun is the center of our Solar System and our local star. It has no permanent features because it is gaseous- mainly incandescent hydrogen.
We study our Sun with educational program.

Asteroid Belt

Billions of space rocks-asteroids - orbit the Sun within the inner Solar System. Most are in the Asteroids Belt, which lies between the orbits of Mars and Jupiter.
There are three main types of asteroids-those made of rock, those made of metal, and those that are a mixture of the two.
When a meteorite collides with Earth, it can form an impact crater on its surface. 

Mars, the red planet

Named after the roman god of war because of its dusty red appearance, Mars is known as The Red Planet. Along with Mercury, Venus, and Earth, it is one of the four terrestrial planets of the inner Solar System.

The martian moons-Phobos and Deimos are small sattelites with a lower density than Mars. They may be asteroid captured by the Martian gravity.

Olympus Mons is the largest volcano in the Solar System, and Valles Marineris a vast canyon system.

The Earth, our home

Our planet is the only planet with both liquid water and frozen ice that has an atmosphere rich in oxygen, and on which life exists.

Earth is surrounded by magnetosphere that protects it from the effects of the solar wind.

Earth's surface is shaped by plate tectonics. There are eight large plates and many smaller ones. Some consist only of ocean floor, while others include continents.

Transit of Venus

The 2012 transit of Venus, when the planet Venus appeared as a small, dark disk moving across the face of the Sun, is visible in the morning of 6 June 2012, in Oradea.  Transits of Venus are among the rarest of predictable celestial phenomena and occur in pairs, eight years apart, which are themselves separated by more than a century. The previous transit of Venus took place on 8 June 2004, and the next pair of transits will occur on 10–11 December 2117 and in December 2125.
Unfortunately, the sky wasn't clear on 6 June in Oradea.
