"Unveiling the Unthinkable: What If Earth Lost Oxygen for 60 Seconds?"
As you stroll down the quaint cobblestone street, lost in your thoughts, a sudden chill tingles down your spine, bringing with it a gnawing sense of unease. The world around you seems to tremble, buildings quaking and shuddering like fragile dominos. The once serene sky darkens, as if cloaked by an ominous veil. An eerie hush descends, as if nature itself holds its breath, waiting for something cataclysmic to unfold.

Why can't we see stars in space?
When viewing images from spaceships or the International Space Station capturing sunlit objects like Earth or the Moon, there’s a noticeable absence of the dazzling nighttime sky full of stars that we might expect. Unlike the magical scenery we witness on Earth, space often appears empty and lacking in stars due to various factors. Unlike our familiar blue sky caused by sunlight scattering in our atmosphere, the lack of atmosphere in space causes the sky to always appear black. This is because there’s no medium to scatter the light and create a blue appearance. However, despite the darkness, if you were on the space station, you’d still experience significant sunlight, similar to a cloudless day on Earth. This brightness affects photography too, where short exposure settings are used to capture sunlit objects but result in a lack of visible stars. Contrary to Earth’s beautiful blue-to-orange-red sky at dusk and dawn, watching a sunset on Mars would yield an orange-brown daytime sky that gains a bluish tint during sunset. The reason behind this difference lies in the Martian atmosphere, which contains larger dust particles causing a phenomenon called “Rayleigh scattering.” This scatters blue light, giving the Martian sky its unique appearance. As for the absence of rings around Earth, unlike gas giants, rocky planets like Earth likely did not experience the conditions necessary for ring formation. While theories suggest Earth may have had a ring system in the past due to a collision, this debris possibly contributed to the formation of our Moon. The existence of a mysterious ”Planet Nine” on the fringes of our solar system, believed to be larger and more massive than Earth, remains a debated topic. Water, once considered scarce in space, has been discovered in various forms across our solar system, including on asteroids, comets, the Moon, and Mars. Mars, in particular, has water at its poles hidden beneath ice and dust, while Jupiter’s moon Europa harbors a potentially vast ocean of liquid water beneath its icy surface. Surprisingly, Neptune, despite its distance from the Sun, emits more heat and displays more atmospheric activity than expected.
