How facinating nature is and beyond

The lightning we see is caused by the electricity heating the air to 30,000°C and turning it into plasma briefly. The sound of thunder is also caused by the transformation of air to plasma, which makes the air expand incredibly quickly.

The Andromeda galaxy is 6 times bigger in the sky than the full Moon, it’s just too dim to see with the naked eye. This composite created by Tom Buckley-Houston shows what it would look like at night if it was just brighter.

These are the first test views from Europe’s new $1.4 billion space telescope. The images impress, but the operational ones promise to be even better. Euclid’s success so far is really exciting because, to put it simply, this machine’s purpose is to map out the dark side of our universe by analyzing billions of galaxies that reside up to about 10 billion light-years away.

Just a reminder of how big Earth is compared to the Sun, the Moon is in there too.

The size comparison between Earth and Mars, it seems that a lot of people have this one different in their mind.

NASA’s Mars Curiosity Rover has crossed its 4,000th day on the Red Planet in October 2023.

The Curiosity rover’s wheels after 10 years on the rugged Martian terrain. Curiosity has 6 wheels, each about 50 centimeters in diameter. The wheels are made of aluminum and have cleats for traction and curved titanium spokes for springy support. This thin and unique design helps the rover move over rocks and sandy surfaces, while the flexible spokes minimize damage from the rugged landscape. An interesting aspect of Curiosity’s wheels is the special pattern of holes they have. As the rover moves, these holes imprint a pattern on the Martian surface, spelling out “JPL” (Jet Propulsion Laboratory) in Morse code, the NASA center responsible for the rover.
