alecras2345 Posted January 26, 2018 Share Posted January 26, 2018 Hi im Ash, im 39 from North Wales. I'm interested in Astronomy, I'm more interested in knowing the facts than actually going out observing. I've been interested in Astronomy for a few years but getting nowhere with learning the facts.

SyedT Posted January 26, 2018 Share Posted January 26, 2018 Welcome to the forum Ash! You've come to the right place if you want to learn more, there are many experienced members here (not including me!). Combining observation with learning facts would be the best way to go in my opinion, as observation can lead to many questions, which can then lead to more fact-checking.

alecras2345 Posted January 26, 2018 Author Share Posted January 26, 2018 I am typing facts for myself to learn about the sun, moon and things that are in our solar system. I'm using the Nasa website as it's probably the most reliable source, what do you think? I type into the search box Sun and it comes up with information about the sun. Here is what i've typed so far. I want to type facts on our moon nextSun – Hot ball of glowing gasesMain gases – Hydrogen, HeliumSun shines – Nuclear Fusion Surface - PhotosphereOuter atmosphere– CoronaCore temp – 15 million degrees celsius Surface temp – 6,000 celsius Sun/Earth – 92.96 million milesSunspots- Magnetic field lines breaking through the surfaceSolar eclipse - Moon between Earth and Sun Link to comment Share on other sites More sharing options...

Hope you don't mind but I would like to make a correction! The Sun is not made of gas (idk why NASA says gas) but rather plasma. An entire different state of matter that occurs when you heat up gas to such a temperature that it's electrons break away from the nucleus.

alecras2345 Posted January 26, 2018 Author Share Posted January 26, 2018 So what should my list say? is it ok to use Nasa to get facts? Link to comment Share on other sites More sharing options...
Floater Posted January 26, 2018 Share Posted January 26, 2018 Hi, Ash. Welcome to the forum. Yes, I think it’s more than OK to use NASA as a source for ‘facts’. Galen’s point above is valid but perhaps a little harsh. To my mind, the words ‘glowing gases’ could be forgiven/accepted as describing plasma - which is ionised gas, as Galen writes.

Apologies for appearing to be harsh, not my intention. In my opinion gasses and Plasma shouldn't be interchanged due to the fact they have completely different properties. It would be like comparing Liquid water and water vapor, they have the same H2O compound but have different properties. Not attempting to start an argument, just stating my opinion. You are of course free to use whatever wording you would like. Link to comment Share on other sites More sharing options...
barkis Posted January 27, 2018 Share Posted January 27, 2018 Opinions are free to be expressed, there are no restrictions. Unfortunately some who differ in opinion from others, go off on an argumentative rant, but as long as that doesn't happen, everything is good. At best, it is best to agree to disagree .

alecras2345 Posted January 27, 2018 Author Share Posted January 27, 2018 I'm typing facts now about the moon from https://solarsystem.nasa.gov/planets/moon/indepth Does synchronous rotation mean that the same face of the moon faces earth? How can i word it?? Link to comment Share on other sites More sharing options...
Nyctimene Posted January 27, 2018 Share Posted January 27, 2018 You are right. The appropriate term for this phenomenon is "tidal locking", or "captured rotation". Stephan Link to comment Share on other sites More sharing options...

Do these sound ok, do i need to add important facts? Earth/Moon distance approx– 238,855 miles Moving about an inch further away from earth each year Synchronous rotation – Same side always faces Earth Orbit – 27 days No atmosphere Lunar eclipse – moon passes into Earths shadow during full moon Diameter – 2,158 miles Link to comment Share on other sites More sharing options...
