In this week’s closer look we are going to look at the earth-facing missions that are getting dragged down by our atmosphere and will be forcibly retired by physics in the next few years, again with no replacements in the works
The formation of rocky worlds from dust particles containing ice and carbon, increasing the possibility of aquatic planets similar to Earth.
We take the Moon for granted, but its effect on the Earth is very important. But where did it come from? Did the Earth & Moon form together?
Today we have Cheap Astronomy tries colonising the Solar System. If we did what would we do with the different planets?
The formation of rocky worlds from dust particles containing ice & carbon, increasing the possibility of Milky Way filled with aquatic planets
The inner solar system was a wild and wooly place and the collisions that formed Earth and Venus were likely of the hit-and-run variety
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.
