Observatories need to be in very dark areas so they get the best unhindered view of the night sky. If you go out and look at the sky when you are in the city, the bright lights will hinder your ability to see the stars. If you go out into the country where there are relatively few lights (and fewer smog emissions) you can see the stars much better depending on the weather. Cold weather, more stars. Warm weather, fewer stars.
Tycho Brahe made major contributions to the field of astronomy with his observations of planetary motion and inventions of astronomical instruments to make those observations. The data he collected ultimately contributed to supporting the heliocentric theory of the solar system - which he didn't believe in. Further details and facts on Brahe can be found at the related link below.
Yes. Dallas is one of the most tornado-prone major cities in the country.
Yes, there are images of VY Canis Majoris available online. It is a red hypergiant star located in the constellation Canis Major and is one of the largest known stars in the Milky Way galaxy. Astronomical observatories and space telescopes have captured images of this massive star.
The International Space Station (ISS) construction was completed in 2011. Since then, upgrades and maintenance have been ongoing, but no major construction projects are currently planned for the ISS.
Many people and organizations were involved in designing and building the initial parts of the Hubble Space Telescope.

The Aztec built their cities in the Valley of Mexico, specifically on an island in Lake Texcoco. Their capital city, Tenochtitlan, was founded on this island in 1325 and became a major urban center with causeways connecting it to the mainland.
They built a great road system and built extensive aqua ducts to bring fresh water into major cities. Though that's not all I'd say those would be about the greatest things they did.
Canadians built their major highways east to west in the southern part of the country to facilitate transportation and trade between provinces and to connect major cities.
