An ESA scientific instrument dropped off by China's lunar lander detected negative ions on the far side of the Moon.

      Here is what the article says:

      These ions are created when charged particles from the Sun pelt the lunar surface, causing particles there to react and become negatively charged. Here on Earth, the planet’s magnetic field stops these particles from ever reaching the surface.

      But since the Moon doesn’t have a magnetic field, its surface is extremely vulnerable to these charged particles. Unlike positively charged particles, however, they never make it back into orbit, forcing scientists to study them on the surface instead.

        Yeah, I get that, but why negative ions? Their research seems important, I just don’t understand the significant of the ions.

          Important to know if we ever want a moonbase. Its always been known that ionizing radiation would be an issue without an atmosphere, but this is more solid evidence that they are present on the surface. They also can do cool stuff at the atomic level to form ionic bonds and create thing naturally that we just wouldn’t find here on earth.

        Thanks, but yeah, the article just says the following:

        The observations could have considerable implications for our understanding of what goes on in other spots in our celestial neighborhood that aren’t protected by a magnetic field either.

        “These observations on the Moon will help us better understand the surface environment and act as a pathfinder to explore negative ion populations in other airless bodies in the Solar System,” NILS principal investigator Martin Wieser explained in the statement, “from planets to asteroids and other moons.”

        It doesn’t really say why negative ions are significant, just that they are found in places without a magnetic field and may help us understand similar places. The research seems more in-depth, and the article send to lack important details.

        The Chinese were just caught with having installed a water pipe at one of their most famous “waterfalls” to juice the flow, in what they claimed to be the “dry season”. Chinese online, lol, have complained that no one was ever told about this, and everyone believed it was natural which is why they traveled from such long distances to see it’s natural wonder.

        Never believe the Chinese, China is first and foremost, a liar.

    If you’re believing a single thing the fucking Chinese are reporting scientifically from anywhere about any subject whatsoever, I’ve got a bridge in Brooklyn that I can let you have real cheap

      You should always read scientific publications with a healthy dose of scepticism - not because science isn’t to be trusted, but because trying to falsify it’s results and finding potential issues is an important part of the process.

      If you do that, I don’t see why you should treat Chinese papers differently. Sure, a country with an authoritarian government with a cultural emphasis on face might produce some papers that aren’t factual due to that specifically, but dismissing the scientific output of a nation of over a billion people over that seems backwards.

      This is actually from the European Space Agency. They collaborated with China to deliver the instrument to the moon.
