Which telescope?

You can spot the four moons in modest binoculars, 7×50 or 10×50 being the best for this, and you’ll even be able to watch them weave around the planet night by night. If you have a small telescope where you can increase the magnification depending on which eyepiece you use, you’ll see the planet much more clearly and the moons will be more obvious.

Among the most interesting events to observe in the Solar System are the transits, occultations and shadow transits, where you can watch the shadow cast by a moon move across the surface of Jupiter’s disc. This

Viewing the Galilean moons

Named after their discoverer Galileo Galilei, the four moons which orbit around Jupiter are easily seen in binoculars and small telescopes.

The moons of Jupiter are some of the most fascinating things to observe in the night sky. The reason being is that they change their position from night to night and are relatively easy to see; a pair of 7×50 or 10×50 binoculars will show them well.

First recorded in 1610 by the Italian astronomer Galileo, the moons of Jupiter have proved to be an endless source of fascination for amateur and professional astronomers ever since. Jupiter, we now

How much of Earth's moons? It is interesting

Figure 1 The asteroid 2005 YU55 could be used to the Moon of Earth.

As of today, our planet is only one satellite — the Moon. There is an assumption that once the Earth could be two large moons, until one of them has broken in a collision with another 4 billion years ago, making the moon appear unique topography.

Researcher Michael Granvik University of Helsinki, Finland, and colleagues presented a computer model of the Solar System asteroids flight, confirming that some of them may well have been, or might become satellites.

Life can be found on the satellites of giant exoplanets in the habitable zones

A team of U.S. scientists has shown that about 5% of the gas giants orbiting their stars at a distance, like Earth, are satellites that can support life.

Discovered dozens of planets located in appropriate orbits, and many of them are too hot or gas for life. Simon Porter of Lowell Observatory and his colleagues still call these distant worlds chance 12 thousand simulated hypothetical planets the size of Earth, which had been captured by the gravitational fields of gas giants like Jupiter, located on favorable for life orbits.

All simulated satellites have embarked on an extremely elongated

Deprived of the status of outer moon rarity

Large satellites, the size of which is related to the size of the planets about the same, the correlation between the size of the Moon and the Earth, can be a rocky one in ten of the world. Such a group of scientists presented the findings in an article in Icarus. Short of the portal writes BBC News.

The relative size of the moon (size relative to "their" planet — Earth) far exceeds the relative size of the other moons in the solar system — its diameter is more than a quarter the diameter of Earth. Until now, scientists

Paris: Prometheus steals the stones and the dust of the rings of Saturn




Spacecraft Cassini discovered one of Saturn's moons — Prometheus — pumped to his stuff out of the ring F.

Scientists believe that the moon is responsible for the loop and the density wave within the ring F, and now we see that planetka also deals with "theft"
