What do I already know?

I know what I can see in space using binoculars.

I know what a telescope is.

The suitability of optical instruments

Produce an information leaflet or poster which identifies at least THREE DIFFERENT methods (land and space based) that scientists use to observe and find out about the Universe. Describe the features each has to make them suitable for their purpose.

Naked eye Binoculars Telescopes

What can you see in space just using your eyes?

Describe some of the objects you can see.

What can you see in space using binoculars?

Describe some of the objects you can see.

What can you see in space using telescopes AND space based telescopes?

Describe some of the objects you can see.

Use pictures!!

Then: Discuss on the suitability of each: Which is the best to use?

When? Why?

Think about poor weather conditions, daylight and electromagnetic waves.

The bright fuzzy spot on the sword is the Orion Nebula, a diffuse nebula that appears about twice the size of the full moon

Puppis A is a supernova remnant located about 7,000 light years from Earth.

This new image includes data from Chandra and XMM-Newton and is the most complete and detailed X-ray view of Puppis A to date.

The combined dataset reveals a delicate tapestry of X-ray light left behind by the supernova explosion.

The core region of globular cluster NGC104

A new composite of NGC 4258 features X-rays from Chandra (blue), radio waves from the VLA (purple), optical data from Hubble (yellow and blue), and infrared with Spitzer (red).

NGC 4258 is well known to astronomers for having "anomalous" arms that are not aligned with the plane of the galaxy, but rather intersect with it.

Researchers are trying to understand how the giant black hole in the center of NGC 4258 is affecting the rest of the galaxy.

NGC 4258, also known as Messier 106, is located about 23 million light years from Earth.

The Hubble Space Telescope's launch in 1990 sped humanity to one of its greatest advances in that journey. Hubble is a telescope that orbits Earth. Its position above the atmosphere, which distorts and blocks the light that reaches our planet, gives it a view of the universe that typically far surpasses that of ground-based telescopes. Hubble is one of NASA's most successful and long-lasting science missions. It has beamed hundreds of thousands of images back to Earth, shedding light on many of the great mysteries of astronomy. Its gaze has helped determine the age of the universe, the identity of quasars, and the existence of dark energy.

WHY A SPACE TELESCOPE?

The Hubble Space Telescope is the direct solution to a problem that telescopes have faced since the very earliest days of their invention: the atmosphere. The quandary is twofold: Shifting air pockets in Earth's atmosphere distort the view of telescopes on the ground, no matter how large or scientifically advanced those telescopes are. This "atmospheric distortion" is the reason that the stars seem to twinkle when you look up at the sky. The atmosphere also partially blocks or absorbs certain wavelengths of radiation, like ultraviolet, gamma- and X rays, before they can reach Earth. Scientists can best examine an object like a star by studying it in all the types of wavelengths that it emits. Newer ground-based telescopes are using technological advances to try to correct atmospheric distortion, but there's no way to see the wavelengths the atmosphere prevents from even reaching the planet. The most effective way to avoid the problems of the atmosphere is to place your telescope beyond it. Or, in Hubble's case, 353 miles (569 km) above the surface of Earth.
