Meade 114EQ-ASTR Reflector and Meade 70mm Refracting Telescope. Are these any good to start up with? If so, which one is better? What could I see in space with these scopes? Thanks for ANY help in advance. =)

The 114EQ-ASTR is better than the 70mm Refracting Telescope simply because it is bigger (114mm vs 70mm) but I suspect you will find the equatorial mount confusing. You might check the ones in the source, if you can spend a little more.

I wanted to connect my D50 to my Meade telescope ETX70; I know that I need a T adapter and a T ring but I don’t know which ones specifically to buy. I would be very grateful if anyone could give me model numbers or more information.

I cant be sure but this is for Nikon-

My budget is about $2000-$5000 for a telescope. For a microscope i really don’t have a limit.Probably $30,000. But I want one that I can view chromosomes and DNA

The big three telescope companies are Meade, Celestron, and Orion. Orion tends to have more low cost beginner telescopes.

I want some help to buy a telescope in India.

India has many astronomical societies. All the major towns and cities have one.
One or two of the members in your local club may have a good telescope for sale which will save a lot of money.
Meade, Celestron, Skywatcher, Tal, and many other brands of telescopes are available in India.
The astro club in Chennai is very active. I was there a couple of years ago.
Far south in lovely Kerala there are also a couple of good astro clubs, and on the hills in the Western Ghats the skies are glorious at night with no light pollution from the cities.
Mumbai has a very big astro club (see below) and in New Delhi there is a lot of interest too.
Here is a list of astronomical societies in India.

The largest astronomy club in Mumbai is Khagol Mandal…The Earth and Sky Organisation.

Space Arcade has astro telescope dealers all over India, north and south…click on ‘dealers’

The largest telescope in India is in Tamil Nadu. It is the Vainu Bappu telescope named after Prof. Vainu Bappu, a great Indian astronomer.
I saw it after my trip to Chennai on the way to Kerala. The countryside there is very pleasant.
To see the telescope you can get a train from Chennai or Mumbai to Vaniyambadi and local connections from there by bus.
Visiting is not currently possible but keep an eye on the website for further notifications.
Scroll down to connections and information for the public.

What does the presence or lack of a planetary magnetic field tell us about the interiors of Mercury, Venus,Moon and Mars (e.g., Liquid iron core of the Earth generates the geomagnetic field)?

Well…. it would imply that they have solid cores, as the liquid core is necessary to cause the iron-nickle flow that creates the magnetic field.

I want to major in planetary science and stay in Texas but I don’t think there aren’t any. I’m asking for a list of schools in texas that have it or maybe a suggestion for what i can get a bachelor’s degree in now and then later get a masters in Earth and Planetary Science?

Planetary science is rarely a major, it’s a graduate specialty. I’m not sure what you plan to do with a masters; there’s very little you can do in astronomy if you don’t have a PhD in the field. Major in physics in college and take courses in astronomy, geology, math, and computer science, then apply to a graduate program. The University of Arizona, Cornell, and Berkeley have great planetary science programs at the graduate level.

I don’t understand whether it’s infrared-ness or the structure of it makes it so that it can’t take those incredible pictures that hubble does.

It will, but they will false colour images, as the James Webb Space Telescope takes pictures in the infrared.
That said, the resolution will be less for the simple reason that the infrared wavelengths are longer than visible. Still, I predict they will be amazing, because we will be able to see *inside* dust clouds, a region of space where no camera has gone before.

At least not one with JWST’s resolution.

Hubble orbits at an altitude of 612km. Mass of hubble is 11,100 kg. Mass of Earth is 5.97 x 10^24.
Earth’s radius is 6.38 x 10^6 m. Gravitational constant is 6.67 x 10^-11

Please help.

Use F = GMm/r^2, where G is gravi.constant, M is mass of earth, m is mass of telescope, r is the distance between centre of earth & telescope’s orbit…
Use r = 6.38 x 10^6 + 612000
so r = 6.992 x 10^6
So put all the numbers together and you will get value of F as 90 x 10^3N

My boyfriend is obsessed with space and pictures from the Hubble Telescope. I want to take him somewhere very special and cool where we can either stargaze through a huge telescope or something.. I feel ignorant about the whole subject, is Nasa in Houston any fun?

Well, …, I for one, think it’s cool that you want to do something fun and "space" oriented with your boyfriend. Making time to have special fun activities that you two can do together is a great way to strengthen your relationship! Although, I’ve never been to the Johnson Space Center, It looks like a lot of fun (see the website below). I’m sure you will both have a thrilling time there.

Also, please no "Try Google" answers. Only true Hubble Space Telescope images please. Thanks to everyone!

Over a decade of daily pictures from several sources…including the Hubble..
