We can turn Earth into a giant telescope. According to a recent study titled “The ‘Terrascope’: On the Possibility of Using the Earth as an Atmospheric Lens”, published by David Kipping of Columbia University, our planet offers an opportunity for pronounced lensing.Continue reading Terrascope: Turning Earth into a giant telescope
Now we’re living on a warm, hospitable planet. As Carl Sagan has said “That’s home. That’s us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives.” We, humans, are the unquestionable rulers of our little oasis in a hostile universe. But all things must pass. The life on Earth, even the planet itself, won’t last forever. What’s more, the humans may go extinct before our planet (and probably before the life on it) dies out. Here some possible (and horrible) ways how planet Earth (or, at least, life on Earth) could die.Continue reading How Earth Could Die – 9 Horrible Ways
This amazing photo of the 2019 Solar Eclipse from the Moon’s orbit was taken on July 2, 2019, by the Chinese lunar satellite DSLWP-B (Longjiang-2).Continue reading This is how a solar eclipse seen from the Moon
Earth, our blue planet is an oasis in the vast, cold, and dark space. It is the only planet we know of that can support life. The fossil record tells us that life on Earth has lasted at least 3.5 billion years (the Earth is about 4.54 billion years old), with the oldest physical traces of life dating back 3.7 billion years. And, if some kind of disaster doesn’t intervene, our planet should continue to host life for at least another 1.75 billion years. Here are the 8 things that make life on Earth possible.Continue reading 8 Things that make Life on Earth Possible
Another “putting things into perspective” video which I liked, showing how big space is, and actually how far the nearest stars from us.Continue reading Watch: How far are the nearest stars?
Melodysheep published an amazing video titled “Timelapse of the future: a journey to the end of time”. This experience takes us on a journey to the end of time, trillions of trillions of years into the future, to discover what the fate of our planet, our sun, and our universe may ultimately be.
If this video won’t give you goosebumps, I don’t know what will.Continue reading Timelapse of the future: an amazing video
Have you ever wondered how the Sun would look from the other planets in our solar system? Here is a visual showing the apparent size of the Sun from the planets of the solar system, including Earth.Continue reading Apparent Size of the Sun from other planets
We only see one side of the moon, because it is tidally locked to the planet Earth (tidal locking the situation when an object’s orbital period matches its rotational period). What if the Earth was tidally locked to the Sun?Continue reading What if the Earth was tidally locked to the Sun?
This size comparison of the Sun and the planets in our solar system is going around frequently, but it’s still amazing to see it. Created by the San Francisco-based artist Roberto Ziche,Continue reading Size comparison of the Sun and the planets
What is the biggest star in the Universe? In fact, it is really hard to give an exact answer to this question since the universe is big, neighboring and the other galaxies are billions of light years away from us. But, we can give it a try. Here are the top 6 biggest stars in the Universe currently known by radius.Continue reading Top 6 Biggest Stars in the Universe
