Young Mars featured a dense atmosphere and water resources
Yet, over the past billions of years, the Red Planet has lost much of both its gas envelope and its hydrosphere.
Nevertheless, Mars has still managed to retain some water in the form of subsurface ice deposits. Data collected by spacecraft suggest that they are much more widespread than previously thought.
According to some estimates, up to one-third of the planet contains hidden deposits of water ice

NASA has decided to extend the Ingenuity drone mission until September 2022!
The vehicle is currently making a series of flights toward the ancient Mars River Delta. Ingenuity will be used to conduct aerial reconnaissance and survey objects beyond the rover's reach

The temperature "inside the lightning" can reach 30,000 kelvin Whereas the temperature on the surface of the Sun is only 6,000 Kelvin (5,700º C).
Yet one cannot claim that lightning is hotter than the Sun, as the layer of the luminary is the coldest one. The plasma inside the Sun attains a temperature of about 15 million kelvin, while the Sun's atmosphere is 500,000 kelvin

The Carina Nebula extends more than 300 light years It's one of the largest areas of star formation in the Milky Way
On a dark night, this nebula is easy to spot in the sky, even with the naked eye. Yet only visible in the southern hemisphere, as it lies 60 degrees south of the celestial equator

Where lies the center of the Universe? According to the cosmological principle - all points of the Universe on large scales are equal.
Thus, neither the center nor the edge of the Universe exists. Or, perhaps, we could say it differently: the Universe has a center everywhere

The greatest geomagnetic storm in history On September 1 to 2, 1859, the largest geomagnetic storm ever caused by a solar flare occurred.
During the storm telegraph systems all over Europe and North America failed; auroras were observed throughout the world, even over the Caribbean
