Arecibo radio telescope collapses One of the most famous telescopes on the planet, the Arecibo radio telescope in Puerto Rico, collapsed on Tuesday, December 1 after fifty-seven years of operation. The Arecibo radio telescope was used by astronomers around the world and made it possible to discover the first planets orbiting a star outside the Sun.. Two of the cables that supported the 900 tonnes of telescope instruments broke on August 10 and November 6, for an unknown reason. The fall of the cables had pierced the satellite dish. The telescope was then deemed very unstable and unrepairable and was to be demolished. Access to it had since been banned for fear of a sudden collapse, which finally took place just before 8 p.m.. on the 1st of December.- Comparing the sizes of the universe In this video we compared the sizes of planets, of stars, of black holes and galaxies.
- The explosion of a star (Supernova) The great Flash from the explosion of a star occurs in this 3D animation, based on photometric observations made by NASA's Kepler space telescope. In animation we see a red supergiant star that is 500 times larger and 20.000 brighter than our Sun. When inside the star can no longer sustain the nuclear fusion, the core of collapsing by gravity. A blast from the collapsing rushes outward through the layers of the star. The blast initially breaks the visible surface of the star with a series of plasma explosions. Only 20 minutes later, the full power of wstikoy wave reaches the surface and the star collapses to a supernova explosion. By closely monitoring the star KSN 2011D located one,2 billion light years away, the Kepler telescope recorded the start of backfiring and the ensuing explosion.
- Kepler 452B: The NASA discovers a planet similar to Earth The Mission of NASA's Kepler telescope, confirmed the first planet located in the "habitable zone" around a star like the Sun. The Kepler-452B is the smallest planet discovered to date in orbit in the habitable zone - the region around a star where water could be collected on the surface of a planet in orbit - G2-type a star like our Sun.
- How petty is the speed of light on the scale of the universe In our opinion the terrestrial globe, the speed of light seems incredibly fast.

- Because in some areas of the Earth it does not get dark In some areas of the Earth during the summer, the Sun remains visible for over 24 hours or even months without getting dark. This phenomenon is called "Midnight sun" and is observed at latitudes above the Arctic Circle and below the Antarctic Circle. The phenomenon is due to the inclination of the vertical axis of the Earth by 23 ° 26΄ in relation to its plane of rotation around the Sun.. Its duration depends on the latitude, from which we observe it. The closer the observer is to the north or south pole, the longer it lasts. For example, the sun shines continuously for 6 months on the poles, while in the northern tip of Finland it is limited to 73 days. The opposite phenomenon, where the night lasts for more than 24 hours during the winter, it is called "Polar Night".
