Saturn’s Moon Titan

Saturn’s Moon Titan

Titan, the largest Moon of Saturn and the only moon in the Solar System known to have clouds and a dense atmosphere. It is the only body other than Earth that is known to currently have liquid on its surface. It was discovered telescopically in 1655 by the Dutch scientist Christiaan Huygens—the first planetary satellite to be discovered after the four Galilean moons of Jupiter. In an Earth-based telescope, Titan appears as a nearly featureless brownish red globe, its surface permanently veiled by a thick haze. It is larger than the planet Mercury and more massive than Pluto, and, in significant ways, it resembles a planet more than it does a typical...
The Last Star in the Universe: What is Red Dwarf?

The Last Star in the Universe: What is Red Dwarf?

  One day and the last star will die, and there will be darkness in the Universe forever. This last star will most likely to be a red dwarf – a small and relatively cold star of the main sequence, a late K or M spectral class. What’s more – the Planets around it are one of the most suitable places where we could find extraterrestrial life. Or even a home of humankind before our own Solar System has become uninhabited. What do we know about red dwarfs and why are our last hope? This interesting video of Kurzgesagt –...
Hoba – The Earth’s Largest Meteorite

Hoba – The Earth’s Largest Meteorite

Have you ever wondered what is the biggest meteorite that have crashed to Earth? The answer is – Hoba. The meteorite hit the Earth about 80,000 years ago, but was only discovered in 1920 near Grootfontein – Namibia, by farmer Jacob Hermanu. While plowed one of his fields, he came across with a 66-ton piece of iron, nine feet long by nine feet wide and three feet thick. Despite its size, Hoba did not form a giant crater because scientists believe it has fallen at a small angle and has been greatly amused by the Earth’s atmosphere. Over the years,...
What is the Difference Between an Asteroid, a Meteor and a Meteorite?

What is the Difference Between an Asteroid, a Meteor and a Meteorite?

  The three are often mistaken – especially when two of them flew near the Earth in the same day, as happened about 10 days ago.Here you can find a short explanation. Asteroids are rocky objects in space smaller than planets. They’re sometimes called minor planets or planetoids, according to NASA It is believed to be the remains of the protoplanetary disk from which the planets in the Solar System are formed. Millions of asteroids circling in orbit around the Sun, about 750,000 of which in the asteroid belt between Mars and Jupiter. Some have even their own satellites. The meteor is...
It Turns Out That Our Moon Once Had an Atmosphere

It Turns Out That Our Moon Once Had an Atmosphere

A new study showed that the Moon had an atmosphere 3 to 4 billion years ago. It was formed when volcanic eruptions have shaken our companion and trowed out gases over its surface, as their speed was too high to be scattered in space. Now days, our Moon has no atmosphere because the magnetic field and the mass are not strong enough to hold it. Unlike the Earth, that keeps its atmosphere, any Moon’s atmosphere would be quickly taken away by the Solar Winds. But some time ago the situation was not like today, even if it was for astronomical...
The Sun

The Sun

For thousands of years people have been looking at the sky and wondering what those objects are all about. The glittering stars and the Sun have always hid a certain amount of mystery and beauty. For astronomers, the Sun is just a dying star. For everyone else, however, it is a huge burning ball that gives us light, warmth and life. So far so good. But what really burns our Sun? It is a well-known fact that there is no air in the cosmos. Accordingly, there is no oxygen to burn. Our everyday experience tells us that burning is a...
