Here is a new series which I’ll use to post fascinating science-related links I come across on the internet.
First of all, consider this image of a giant space squid
Secondly, this article about the Moon is rather long, but not overly scientific. About two-thirds down, it says “the Moon may still have a molten outer core”. Wow, just wow. I don’t know if there is a geologist in the house who can tell us about how, failing drilling in the surface, we can determine how warm a planet is at what depth, but it would be amazing to discover that the Moon is not as cold and dead as we thought.
Added to the above link, history is being made sooner, rather than later, with private space flight edging close.
Recently, astronomers have discovered trojan asteroids in Earth orbit. Trojans are objects that share the same orbit as their ‘host’ body, usually at a gravitationally stable point, such as the L4 and L5 Lagrange points. Because they share the same orbit as Earth without even being in danger of colliding with it, they are extremely hard to detect, because they’re near the Sun when seen from Earth, and you only get a bit of time after sunset or pre-dawn to observe them. It’s also thought that the Lagrange points are collection points for various items of natural space junk, and people have long been talking about sending missions there. That may happen since we now know there is something hanging around there for us to investigate.
