Embark on an Astronomical Journey - 7 Amazing Space Facts You've Never Heard Before! ?✨

Welcome, space enthusiasts! In today's video, we're going beyond our blue planet to explore the vastness of the cosmos. Prepare to have your mind blown by seven incredible facts about the universe that will make you see space in a whole new light.

The Andromeda–Milky Way collision is an astronomical event expected to happen in about 4.5 billion years, involving the two largest galaxies in the Local Group. It is believed that the stars within these galaxies are spaced out enough to make individual collisions unlikely, although some stars will be ejected from their respective galaxies.

The footprints of the Apollo astronauts are expected to remain on the moon's surface for at least 100 million years, as there's no wind or water to erode them away. However, the moon is still bombarded by micrometeorites, causing very slow erosion over time.

A day-night cycle on Venus is remarkably long, taking about 243 Earth days due to its slow rotation in the direction opposite to its orbit around the Sun. Interestingly, a Venusian year is shorter than a Venusian day, with the planet completing its orbit around the Sun in 225 Earth days.

Astronauts on the International Space Station (ISS) witness approximately 16 sunsets and sunrises every day due to the ISS completing an orbit around Earth every 90 minutes. This rapid orbiting creates an exceptional experience for those aboard the ISS.

Olympus Mons, the giant shield volcano on Mars, is about three times the height of Mount Everest and nearly as wide as France. It stands as one of the largest volcanoes and the tallest planetary mountain discovered in the Solar System.

Earth's orbit contains a significant amount of space debris, also known as space junk. As of November 2022, the US Space Surveillance Network reported 25,857 artificial objects in Earth's orbit, including operational satellites and various pieces of debris. This debris poses a risk to spacecraft due to the potential for collisions, which can cause damage similar to sandblasting
