Earth-like planet and another 5 incredible space discoveries this year

Землеподобная планета и еще 5 невероятных космических открытий этого года

The star alpha Centauri system – the nearest to the Solar system – has long been known and repeatedly action sci-Fi novels took place there. But I guess if the writers of how close they may have come to the truth?

A planet the size of Earth at alpha Centauri

Breaking news recently published space Agency NASA, scientists intend to focus on the study of the planets in the alpha Centauri system, which is at a distance from its star that it may be suitable for life.

In order to understand what was going on, we must remember that the star system alpha Centauri consists of three stars – alpha Centauri A, alpha Centauri and Proxima Centauri – the closest is a red dwarf in orbit of which has been discovered a new planet.

To enjoy scientists are not in a hurry, by publishing his discovery with dozens of reservations and caveats. The planet really is at this distance from the star, which allows you to be on liquid water, but the presence of the atmosphere they are not sure. In addition, Proxima Centauri is smaller and cooler than the Sun, the planet can rotate around the star, and substituting the only one your side, as it happens with the Moon and Earth.

The discovery was not accidental, it happened in the study of and search for exoplanets. The program which is now working in NASA. For further movement in 2018 is expected to launch a new Space telescope James Webb, an orbital infrared Observatory, his mirror and power will be more than two times higher than working in the orbit of Hubble.

1284 planet Kepler, and the youngest of them

In may, NASA published a report on the work on the study of exoplanets – planets outside of our system, it turned out that their scientists have discovered more than 1 million Discoveries were made using the same telescope, which helped discover the planet and the nearest star system – Kepler.

The Kepler Telescope

We should dwell on the principle of the telescope, it captures the discrete signals of distant planets – the reduction in brightness that occur when planets pass in front of their stars.

So, from almost 1.3 thousand planets with a solid surface has approximately 550 celestial bodies and potentially habitable – 9, and their distance to the stars allows the existence of liquid water and atmosphere.

This telescope has helped astrophysicists to detect the youngest of the known planets – K2-33b. Her age is only 5-10 million years (the estimated age of the Earth 4.54 billion years), in size it is little more than Neptune. Scientists hope that studying it will help them to better understand how newborn planets relative to their stars, K2-33b, for example, is 10 times closer to its star than mercury to the Sun.

Galaxy at a distance of 32 billion light years

Galaxy GN-z11 telescope “Hubble” discovered in March of this year, and it is the most distant object in the Universe known to mankind.

The Hubble Telescope

GN-z11 is in the constellation the Big dipper, and the light that was observed by scientists, was from the galaxy to us 13.4 billion years. In other words, Hubble sees the galaxy for what it was 400 million years after the Big Bang. Scientists theorize that the galaxy is 25 times less than the milky Way.

Due to the expansion of the Universe, the concomitant distance to the galaxy is about 32 billion light-years.

Galaxy GN-z11 found by using a wide-angle camera 3, installed during the last servicing of the telescope in 2009.

A supernova in the networks of the astrophysicists

In March all the same, Kepler, famous for his successful hunt for exoplanets, astrophysicists presented the next production – the first telescope recorded the explosion of a supernova in the range of optical waves, that is to say, removed it.

The explosion of a supernova, like a plane crash, it is impossible to predict which of the stars will explode in the next moment. And so the scientists were lucky! Since 2011, they watched a pair of stars KSN KSN 2011a and 2011b, and now five years later the explosion occurred.

Data obtained with a telescope, confirmed by dozens of hypotheses and clarify the questions of life and death of stars.

The proof of correctness of Einstein

In February, the scientific community was excited by the discovery, which is a confirmation of the hypothesis of the genius of albert Einstein – gravitational waves exist!

Found out about this thanks to the merging of two black holes that are billions of light-years from our planet. Scientists have converted to sound waves: it was a noise like the noise of blood flow, or breath.

What’s so important about the discovery? On the one hand a follow-up study of gravitational waves, which, according to the theory, filling the Universe since the Big Bang, will help you better understand the process of formation of reality on a global scale. But the more ambitious scientists see in gravitational wave way to travel in time and space – as in the wildest dreams of science fiction.

Photo album of the Solar system

At the beginning of last century atlases collected pictures of rare and exotic corners of our planet, so at the beginning of the XXI century, scientists collect a photo album of our solar system. Every day pictures of neighboring planets are becoming better, we can see them in the colour of the distant Jupiter, earth, Mars, the rings of Saturn.

The satellites that explore the Solar system, do not get tired to send us new pictures of the land that the mankind is getting ready to conquer today.
