The most impressive findings about the universe in 2012 (1)

The astronomical industry welcomed the impressive discoveries in 2012, which changed the way people knew about the universe, and pushed some devices to the critical level of their capabilities.

The following are the findings that made the astronomical world in 2012, according to

The biggest black hole

Surely observers would never want to get close to the galaxy NGC 1277 of the British constellation or its central black hole, which accounts for a large part of this galaxy. That black hole is 17 billion times more massive than the sun, accounting for 14% of the total mass of the galaxy, a terrible rate compared to the usual 0.1% in most galaxies in the universe.

The large size of the black hole at first caused scientists to not believe their eyes, and they spent more than a year rechecking all the data before officially announcing it recently.

The planet is closest to Earth

In a surprising discovery, astronomers identified an Earth-sized planet in neighboring star systems. Stone planets are found at Alpha Centauri (formerly known as Southern Mon), a three-star system about 4.3 light-years away.

Life can hardly exist on the surface of Alpha Centauri Bb planet, is thought to be heated by the distance too close to the central star, 6 million km away, while the distance from the sun - Earth is 150 million kilometer.

The smallest world

Astronomers used NASA's Kepler space glasses and found three tiny planets 120 light-years from Earth. Turning around, KOI-961, the smallest of these is the size of Mars, and all are smaller than Earth. Even the central star itself is not much better in size, only about 70% bigger than Jupiter.

'This is the most crowded star system ever discovered,' said John Johnson of the California Institute of Technology in Pasadena (USA).

The smallest solar system

KOI-500 has five planets crowded together in tight spaces, causing their gravitational force to push each other intensely during the process around the central star. The years of these planets last only 1 - 3 - 4.6 - 7.1 and 9.5 days. And yet, their size is not much higher than Earth, only about 1.3 to 2.6 times the globe.

The whole operation of the upper solar system must manage in an area that is 150 times smaller than Earth's orbit. 'With this ratio, you can easily insert 10 more planets and they are still inside the Earth's orbit,' says Darin Ragozzine, planetary scientist at the University of Florida in Gainesville (USA).

The farthest galaxy

Just like the world record on the 100 meter speed track, the farthest galaxy record always changes over time. The galaxy that is filled with hope for this title is now UDFj-39546284, pictured when the new universe is 380 million years old. Its age has been confirmed in 2012 thanks to new data provided by Hubble.

The galaxy belongs to a group of seven galaxies that experts expertly surveyed, probably formed 400 to 600 million years from the Big Bang event that created the universe 13.7 billion years ago.

The new image of Hubble Ultra Deep Field (HUDF) in 2012 revealed the previously undiscovered location of the seven galaxies.

The farthest supernova explosion

In 2012, astronomers described a phenomenon that they later claimed to be the earliest and earliest supernova explosions, with one case 10.4 billion years ago and the other 12.1. billion years.

Experts believe that some 'super-bright' supernovae come from giant stars, 100 to 250 times the mass of the sun. They exploded and launched material into space for billions of years ago.
