Space Is Utterly Silent

Due to its vacuum nature, space lacks air or an atmosphere, making it impossible for sound waves to propagate. Therefore, if you were to scream in space, no one would hear you, regardless of how loudly you shout. Nevertheless, radio waves can still traverse this environment, allowing astronauts to communicate via radios, which is the only sound wave type capable of transmission in a vacuum.

The first video titled "10 Facts About: Space" delves into more astonishing revelations about the universe, offering viewers a closer look at its mysteries.

Venus: The Hottest Planet

Venus reaches scorching temperatures of 450 degrees Celsius (about 232 degrees Fahrenheit), which is lethal for humans. Interestingly, one might assume Venus is closest to the sun, but that title actually belongs to Mercury, which is a comparatively cooler 167°C (333°F).

Life on Mars?

Mars is often viewed as the only planet within our solar system, other than Earth, that may support life. In 1986, NASA discovered what they believed could be microscopic fossilized organisms, though skeptics argue that evidence is lacking. Today, scientists continue to investigate the possibility of human habitation on Mars should Earth become uninhabitable.

The Star Count Conundrum

Given the vastness of space, accurately determining the number of stars remains a daunting challenge. However, astronomers estimate that our galaxy, the Milky Way, contains between 200 and 400 billion stars.

Halley's Comet: A Long Wait

Discovered in 1705 by Edmond Halley, Halley's Comet graces our skies approximately every 75 to 76 years, with its last appearance in 1986. Its next orbit around Earth will not occur until 2061.

Diamond Planet Discovery

A rocky planet known as 55 Cancri e, located 40 light-years away and visible to the naked eye in the constellation Cancer, is believed to potentially have a surface composed of diamond and graphite. It’s twice the size of Earth and possesses eight times its mass, according to research conducted by Yale University scientists.

Moon Footprints: Here to Stay

The absence of an atmosphere on the moon means there is no wind or water to erode or wash away the footprints left by Apollo astronauts during the 1960s and 70s. As a result, these marks, along with discarded materials, will remain for millions of years.

Venus's Unique Rotation

On Venus, a single day lasts longer than a year. Its slow axial rotation requires 243 Earth days to complete one full rotation, while its orbit around the sun takes only 225 Earth days, making its year shorter by 18 days compared to its day.

Floating Water in Space

A remarkable discovery of a water vapor cloud, containing 140 trillion times the mass of Earth's oceans, has been made billions of light-years away. This finding represents the largest amount of water ever detected in the universe.

Uranus: The Gas Giant

Uranus, often the subject of jokes, is classified as a gas giant. Its atmosphere is primarily composed of hydrogen, helium, and trace amounts of methane.
