How Many Moons Does Our Planets Have in Our Solar System?

There is no secret that the Earth has only one natural satellite (our Moon), which is thought to have formed about 4.51 billion years ago, but how many moons are there in our Solar System? In the Solar System we have some planets that don’t have any other moon, but we have some planets that have approximately more than 53 moons such as Jupiter.

Astronomers Discovered Thousands of Black Holes at the Center of Milky Way

Astronomers Discovered Thousands of Black Holes at the Center of Milky Way

Astronomers announced the discovery of thousands of black holes last months, at the center of the Milky Way. The data was provided by NASA’s Chandra X-ray Observatory. “This black hole bounty consists of stellar-mass black holes” which are estimated to be five to 30 times the mass of our Sun. These new black holes were discovered within three light years of the supermassive black hole at our Galaxy’s center, called Sagittarius A*.

The Biggest Black Holes are Outgrowing Their Galaxies

The biggest black holes are growing faster than the rate of stars being formed in their galaxies, in accordance with two new studies using data from NASA’s Chandra X-ray Observatory and other telescopes. More than many years, astronomers have collected data on the arrangement of stars in galaxies and the growth of the biggest black holes (that is, those with millions or billions the mass of the Sun) in their centers.

10 Awesome Facts About The Sun

The Sun is the star at the center of our solar system and is responsible for the Earth’s climate and weather. It is an almost perfect sphere with a difference of just 10km in diameter between the poles and the equator. The average radius of the Sun is 695,508 km (109.2 x that of the Earth) of which 20–25% is the core. Its gravity holds the solar system together, keeping everything from the biggest planets to the smallest particles of debris in its orbit. Electric currents in the Sun generate a magnetic field that is carried out through the solar system by the solar wind. The connection and interactions between the Sun and Earth drive the seasons, ocean currents, weather, climate, radiation belts and aurorae. There are billions of stars like our Sun scattered across the Milky Way Galaxy. Today we have prepared 10 awesome facts about the Sun that will arouse your curiosity.

15 Facts about Galaxy that You Force to Know

A galaxy is a massive, gravitationally bound system that consists of stars, stellar objects (such as brown dwarfs and neutron stars), an interstellar medium of gas and dust, black holes, and an unknown component of dark matter. Examples of galaxies range from dwarfs with as few as ten million stars to giants with a hundred trillion stars or more, each orbiting through their galaxy.

Blue exoplanet HD 189733b

The Earth is not the only blue planet in the universe – Hubble telescope discovered blue exoplanet HD 189733b

For the first time Scientists from Great Britain could define color of a planet out of Solar system. With help of pictures from Hubble telescope they established that the gas giant in constellation of Chanterelle is painted in bright blue color. Thus they explained that as the reason of such coloring serve not water oceans, as on Earth, and the melted glass. Astronomers could define color of a planet, having tracked how the range depending on the provision of a planet in relation to the star changed. The first of them is- when the planet was closed from supervision by a star, and the second – when it was in a visibility range.

Galaxy absorption of gas

Very Large Telescope captured galaxy absorption of gas

Astrophysics from the Southern European observatory (ESO) photographed a galaxy’s absorption of gas clouds surrounding it. The new data obtained with help of Very Large telescope (VLT) are remarkable that the galaxy is removed from Earth on distance more than ten billion light years. And respectively it is visible in that look in which was during an era of the young Universe. As at such distance the galaxy appears the smallest even at supervision through Very Large telescope (VLT), astronomers had to use indirect methods for an assessment of volume of absorption of gas and definition of details of process.
