NASA Announces 10 New Earth-Sized Planets Orbiting in Habitable Zone

On June 19, 2017, NASA’s Kepler space telescope team has released a mission catalog of planet candidates. The final catalog introduces 219 new exoplanet candidates, and 10 of them are near-Earth-size and orbiting their stars in the circumstellar habitable zone. Notes 1

Ancient carvings in Göbekli Tepe show a comet hit Earth 13,000 years ago

Ancient symbols carved into stone at Göbekli Tepe (an archaeological site in Turkey) tell the story of a big comet impact more than 13,000 years ago, scientists think. The devastating impact triggered a mini ice-age that drove many mammals weighing more than 40 kg to extinction. According to an article published by New Scientist, carvings made on […]

7 Earth-Sized Planets Found Orbiting Nearby Star TRAPPIST-1 and 3 of them are in the Habitable Zone

On February 22, 2017, NASA has announced that seven Earth-sized planets have been observed by NASA’s Spitzer Space Telescope around TRAPPIST-1, a tiny, nearby, an ultra-cool dwarf star located 39 light-years (12 parsecs; 370 petametres) away from Earth in the constellation Aquarius. The good news is: three of these planets are firmly in the habitable […]

51 Pegasi b: water found on the exoplanet

Scientists spotted water in the atmosphere of 51 Pegasi b, one of the first exoplanets ever been discovered. It is around 50 light-years away – so we can call it a “nearby” exoplanet – and it is in the constellation of Pegasus. 51 Pegasi b has not marked a breakthrough in astronomical research for the […]

Leaving Solar System at the Speed Of Light

Our Solar system is big, and vast, despite it is really small compared to our galaxy, not to mention the complete universe. To put this into a perspective, you can think of yourself as a photon emitted by the Sun. It takes about 8 minutes to reach the Earth after a photon has been emitted […]

Great American Total Solar Eclipse 2017

There will be a total solar eclipse on Monday, Aug. 21, 2017, and the United States will be the best country to watch. It will be also the first total solar eclipse to go coast to coast in the U.S. in 99 years. From Oregon to South Carolina, 70-mile Moon-shadow will race across the U.S. […]

Two stars may collide and light up the night sky in 2022

Two stars may collide into a stunning “red nova” in 2022 (or a few months earlier, most probably between September 2021 and September 2022), and for a few weeks become one of the brightest objects in Earth’s night sky, scientists predict. When two stars merge, they increase in brightness 10 thousandfold.

If Andromeda Galaxy were brighter, this is what we’d see

Andromeda Galaxy is the farthest object in the sky that we can see with the naked eye. But if you don’t know where to look, you won’t notice it. If it was much brighter, its appearance in the sky would be sensational. The moon is a good reference for what we’d see if our galaxy’s […]
