    I'm having another go at reading Patrick moores book called teach yourself astronomy. im reading the chapter about early astronomy, the book has a section of things to remember from that chapter. Here is what i've got, Astronomy goes back to our cave dwelling ancestors Originally it was thought that the earth was flat and motionless Constellation patterns date back to around 3000 BC True astronomy began with the Greeks Ptolemaic system - Earth lay at the centre of the Universe, with the Moon, Sun, planets and stars moving around it. Stagnation after Ptolemy’s death – Dark ages Revival of Astronomy due to Arabs in the ninth century 1543 AD – Copernicus stated that the Sun not Earth should be at the center of the system 140BC – Hipparchus of Nicaea discovered Precession 240BC - Eratosthenes made an accurate estimation of the Earths size Seventeenth century, the German mathematician Johannes Kepler published his three Laws of Planetary Motion, Ptolemaic system involves epicycles, what do epicycles illustrate, do they show the planets retrograde motion? What's another way of saying Astronomy goes back to our cave dwelling ancestors? Astronomy goes back to stone age/prehistory?
  2. Hi im fed up of cloudy skies, do you know of a site where i can stargaze online, free?

    i have a Meade ETX Spotting scope, not go to, but firstly it has electronic focuser that doesn't work anymore and they've stopped making them, secondly i feel it's too big for what i want, i want to just go to the window and look up with my monocular s.
  4. Hi m y name is Ash, im 39 (nearly 40, OMG!) and i live in north wales. I'm disabled and use a wheelchair. I have an interest in astronomy but due to my disability im unable to go outside at night. Sometimes i look out of the window at the stars and think wow! i also see the moon as its path is in that part of the sky, it faces south. My mate takes me out during the day to go bird watching which i enjoy. I use an Opticron 10x25 monocular for bird watching, I was wandering, could i use the same monocular to point at the window to see the stars? I know the window will distort the image but if i could just see the moon with them would be good. The sky is hardly ever clear here but on the odd occasion like now the skies are clear.

    Hi I don't seem to be getting notified of replies. I am interested in learning facts about space, so I've been getting facts about the sun and earths moon from NASA website. I also have a Patrick Moore book which has different figures and information than NASA, but the book is to much to read. The NASA suite has quick facts but not enough, only a few facts. Shall I ignore Patrick Moore's book and stick with NASA or what, I don't know what to Do for the best??

    facts

    How do these sound about the moon? Earth/Moon distance approx– 238,855 Moving about an inch further away from earth each year Synchronous rotation – Same side always faces Earth Orbit – 27.3 days Elliptical orbit Exosphere – Very thin atmosphere moon Diameter – 2,158 miles Lunar eclipse – moon passes into Earths shadow Affects tides on Earth

    facts

    Hi I'm trying to teach myself various facts about the objects within our solar system by looking at the Nasa website. I'm not sure what facts to take, I know the distance is good to know, how long is a planets orbit, how long a planets rotation period is but what other facts should i know? Here are the facts i've got about the moon. Any other facts i should add? I have started facts on the moon from https://solarsystem.nasa.gov/moons/e...moon/overview/ . 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

    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??

    So what should my list say? is it ok to use Nasa to get facts?

    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

    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.

  14. Hi my name's Ash and I'm from Wales. I'm reading a book called Teach yourself Astronomy by Patrick Moore. It has chapters on introducing Astronomy, early Astronomy, the sun the inner planets and I'm trying to memorize a few facts. I feel I'm not learning much, I think it's a little basic. I want to gain knowledge on astronomy but some parts are too basic.
  15. Hi im disabled and use a wheelchair, i enjoy looking at the planetarium on my computer, instead of going out stargazing, is it ok to stargaze on my computer looking at the planetarium? i don't have a scope connected.
