Hubble Space Telescope Module.<\/strong><\/figcaption><\/figure>\n<\/div>\n\n\n\n\nLaunched in 1990, the Hubble Space Telescope has revolutionized our view of the universe, capturing stunning images of distant galaxies and nebulae. Its powerful lens allows us to look back in time to about 13.4 billion years ago, just after the Big Bang. <\/p>\n\n\n\n
Hubble’s contributions to science are immense, with over 15,000 published papers and 738,000 citations, making it an invaluable tool for astronomers.<\/p>\n\n\n\n
5. Nobody knows how many stars are there in space.<\/h2>\n\n\n\n Estimating the universe’s vastness, astronomers suggest there might be around 200 billion trillion stars, making space a realm of endless wonder. This number comes from multiplying the Milky Way’s stars by the galaxies we know exist. <\/p>\n\n\n\n
Yet, despite these deep space facts, the true star count remains a mystery, showcasing the universe’s incomprehensible scale and beauty.<\/p>\n\n\n\n
6. Space-time began with the Big Bang, as per the theory of general relativity.<\/h2>\n\n\n\n Albert Einstein’s general theory of relativity, formulated in 1916, revolutionized our understanding of space and the universe’s origins. It suggests that space-time, the fabric of the cosmos, began with the Big Bang. <\/p>\n\n\n\n
This theory, with its elegant mathematical framework, explains how matter influences space-time’s curvature, leading to the conclusion that the universe is not static but expanding.<\/p>\n\n\n\n
7. Why can’t sound travel in space?<\/h2>\n\n\n\n Space is silent<\/a> because it’s a vacuum with no air for sound to travel through. While you can’t hear anything in the emptiness of space, astronauts can still talk to each other using radios. <\/p>\n\n\n\nThis is because radio waves, unlike sound, don’t need air to move, allowing communication across the vast, quiet expanse of space.<\/p>\n\n\n\n
8. Space has a water cloud with 140 trillion times Earth’s ocean water.<\/h2>\n\n\n\n
