Hubble Space Telescope
The Hubble Space Telescope is a powerful space telescope that orbits the Earth, providing astronomers with incredible views of the universe. It was launched into orbit by the Space Shuttle Discovery in 1990 and has since provided stunning images and valuable scientific data.
Key Features of the Hubble Space Telescope:
- High-Resolution Imaging: Hubble's primary function is to capture high-resolution images of celestial objects, including galaxies, nebulae, and stars. Its images have provided valuable insights into the structure and evolution of the universe.
- Ultraviolet and Infrared Capabilities: Hubble is equipped with instruments that allow it to observe celestial objects in ultraviolet and infrared wavelengths, providing a comprehensive view of the cosmos.
- Long-Term Observations: Hubble has the ability to observe the same object over an extended period, allowing astronomers to study changes and phenomena that occur over time.
- Repair and Upgrades: Over the years, astronauts have conducted several servicing missions to repair and upgrade Hubble's instruments, ensuring its continued operation and scientific productivity.
Scientific Discoveries Enabled by Hubble:
The Hubble Space Telescope has contributed to numerous groundbreaking discoveries in astronomy, including:
- Confirmation of the existence of supermassive black holes at the centers of galaxies
- Measurement of the rate of expansion of the universe, leading to the discovery of dark energy
- Identification of exoplanets orbiting distant stars
- Observations of distant galaxies, providing insights into the early universe

Earth/Space Science: Students will use scientific skills and processes to explain the chemical and physical interactions (i.e., natural forces and cycles, transfer of energy) of the environment, Earth, and the universe that occur over time.
Earth History: Explain how sedimentary rock is formed periodically, embedding plant and animal remains and leaving a record of the sequence in which the plants and animals appeared and disappeared.
Explain how sedimentary rock buried deep enough may be reformed by pressure and heat and these reformed rock layers may be forced up again to become land surface and even mountains.
