NASA’s Hubble Space Telescope took this spectacular photo of Saturn and its rings on July 4, 2020, when the ringed gas giant was 839 million miles (1,35 billion kilometers) from Earth.

On Jul 20, 2020, scientists have released what they call the “most-detailed 3D map of the universe ever produced”. This incredible map shows 11 billion years of the Universe’s history, with galaxies closest to Earth appearing in purple & blue, and distant galaxies in yellow & red.
Russian cosmonaut Ivan Vagner published a spectacular comet photo on his Twitter account (@ivan_mks63). He tweeted both in Russian and in English and said “During the next revolution I tried to capture the C/2020 F3 (NEOWISE) comet a bit closer, the brightest one over the last 7 years. Its tail is quite clearly visible from the International Space Station!”
How the moon was formed? The most widely accepted theory of the Moon’s origin is known as the Giant Impact Hypothesis. The standard giant impact hypothesis, sometimes called the Big Splash, or the Theia Impact suggests the Mars-sized body, called Theia, impacted Earth, creating a large debris ring around Earth, and the Moon formed out of that debris. The hypothesis additionally suggests that this collision also resulted in the 23.5° tilted axis of the earth, thus causing the seasons.
Planet Nine is a theoretical, undiscovered giant planet in the mysterious far reaches of our solar system. The presence of Planet Nine has been hypothesized to explain everything from the tilt of the sun’s spin axis to the apparent clustering in the orbits of small, icy asteroids beyond Neptune.
But does Planet Nine actually exist?
Well, of course, you cannot see a black hole – but the newly discovered one has two stars orbiting it, and you can see these companion stars even with the naked eye from Earth. The triple system is named HR 6819. Named QV Tel Ab, the inner component of the system is the closest black hole to Earth.
The system appears as a variable star that is dimly visible to the naked eye.
This awesome map, using imagery taken by NASA’s Lunar Reconnaissance Orbiter (LRO), enables us to explore Moon within our browsers.
All stars emit varying amounts of light over time – and the Sun is no exception. Such changes in starlight can help us understand how habitable any planets around other stars are – a very active star may bombard its planets with harmful radiation. Now a new study, published in Science, shows that the Sun is significantly less active than other, similar stars.
A new Earth-sized planet named Kepler-1649c orbiting its star in the habitable zone has been detected by a team of scientists, using reanalyzed data from NASA’s Kepler space telescope, NASA has announced.
