In today’s episode, we’re going to look at everything from how past Earth couldn’t support photosynthesis because the days were just too short, to current Earth letting us get hit by more Cosmic Rays prior to Earthquakes going off, and to supernovae threatening our world while alien stars eat other planets.
Each week, when we set off to do this show, we start with one core idea: We want to tell you what is new in space and astronomy… and remember Earth is a planet too.
It’s time for another series! This time we’re gonna look at the missions that’re currently in place across the solar system. We’ll start with the key missions here on Earth
For decades, scientists have been trying to work out just how the Earth got all its water, and the prevailing theory was that comets and asteroids brought it, and we have evidence for that mechanic; however, a new hypothesis has provided evidence that the water was already here, locked away in hydrous minerals in a very iron-poor core.
Have you ever wondered how old the Earth is? How early scientists tried to get an answer for this puzzling problem, and how modern science has finally given us an answer?
Have you ever wondered how old the Earth is? How early scientists tried to get an answer for this puzzling problem? And how modern science has finally given us an answer by looking at meteorites? More at #365DaysOfAstro
Could we nudge the orbit of the Earth to avoid the death of the Sun? Could it get kicked out of the solar system altogether? What are rogue exoplanets?
Today on #365DaysOfAstro, lets explore on how fast you’re spinning in space right now, and how you’d actually gain a little weight if the Earth stopped spinning. How Fast Does the Earth Rotate?
Why Does the Earth Spin? We’ll tell you straight away without having to hang around until the end of the video. That’s our USP!
Every time we send a spacecraft to another world, our Earth-based lifeforms are going with us. No matter how well we try to keep them clean, a few stowaways will always come along for the ride.
