On Monday, August 21, an estimated 2 million to 7.4 million Americans traveled to see the first total solar eclipse in 99 years to go coast to coast in the United States, which went from Lincoln Beach, Oregon, to Charleston, South Carolina. But, some of them were unlucky, as the weather was overcast in some places. But, …

On February 22, 2017, NASA astronomers have announced that seven Earth-sized planets have been discovered around an ultra-cool dwarf star named TRAPPIST-1 which is located around 39 light-years from the Earth. And what’s more – three of them are orbiting their star in the habitable zone. Now scientists find clues that TRAPPIST-1 system may contain water. Then, …
On September 1, 2017, a potentially hazardous asteroid named 3122 Florence skimmed past Earth from a mere 4.4 million miles (7 million km) distance. The huge asteroid, which is around 2.7 mile (4.4 km) wide, was the “biggest object passed this close to Earth since the NASA program to detect and track near-Earth asteroids began”, …

The Earth rotates from west to east with a linear velocity of 465.1013 m/s (1674.365 km/h) at the equator. But what would happen if the Earth stopped rotating abruptly? Online magazine Tech Insider presented a video demonstrating the development of events in this case.
Why do we see only one side of the Moon? You have probably heard references being made to the “dark side” of the Moon – there’s even a Pink Floyd album with that name. But there’s no “dark side” of the moon because our satellite is not illuminated by the Earth, it is illuminated by the Sun. All …

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 …

A beautiful image published by NASA, taken by the uncrewed Cassini-Huygens spacecraft, shows the Earth between the rings of Saturn. The image was taken on April 12, 2017.
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, discovered in 1995, marked a pivotal moment in astronomy, being the first exoplanet confirmed to orbit a Sun-like star. Located approximately 50 light-years away in the constellation Pegasus, this gas giant revolutionized our understanding of planetary systems. Unlike the gas giants in our solar system, 51 Pegasi b orbits remarkably close to …

What if we could make a spaceship that is capable of leaving the solar system at the speed of light? How much time would it take to enter interstellar space? Our Solar system is big, and vast, despite it being really small compared to our galaxy, not to mention the complete universe. To put this …
