Welcome to the Hubble Space Telescope worksheet! In this worksheet, we’ll explore the incredible technology and discoveries made possible by the Hubble Space Telescope. From its launch in 1990, the Hubble has transformed our understanding of the universe, uncovering mysteries about everything from the origins of galaxies to the nature of dark energy. Join us as we delve into the fascinating world of the Hubble Space Telescope!
The Origin and Launch of the Hubble Space Telescope
The Hubble Space Telescope (HST) was named after Edwin Hubble, an American astronomer known for discovering the expanding universe. The HST was launched into space on April 24, 1990, aboard the Space Shuttle Discovery, and it has since then been orbiting our planet, capturing breathtaking images of the universe.
The Initial Flaw
Shortly after its launch, the scientists discovered a flaw in the telescope’s primary mirror. The mirror was too flat by a margin of 2.2 microns, which caused blurry images. The scientists were quick to come up with a solution and installed a device called COSTAR, which corrected the mirror’s spherical aberration. It was installed on the first space servicing mission in 1993.
The Servicing Missions
Five servicing missions were conducted on the HST to upgrade its hardware, repair damages, and install new instruments. The first mission in 1993 installed COSTAR, the second in 1997 installed the Space Telescope Imaging Spectrograph (STIS), and the third in 1999 replaced the gyroscopes and installed the Advanced Camera for Surveys (ACS). The fourth and fifth missions in 2002 and 2009 installed the Cosmic Origins Spectrograph (COS) and repaired the STIS, respectively.
The Incredible Achievements of the Hubble Space Telescope
The HST has been instrumental in advancing our knowledge of the universe. It has captured stunning images of galaxies, nebulas, and other celestial objects, providing valuable insights into their properties and behavior.
Discovering Dark Energy
One of the most significant discoveries made by the HST is the existence of dark energy, which is believed to be the force behind the accelerating expansion of the universe. In 1998, two teams of scientists used the HST to measure the brightness of distant supernovae, which revealed that the universe was expanding at an accelerating rate, contrary to what was previously believed.
Observing the Birth and Death of Stars
The HST has also provided us with a glimpse into the birth and death of stars. It has captured images of star-forming regions, such as the Eagle Nebula, where massive clouds of gas and dust are collapsing to form new stars. It has also observed the explosive death of stars, known as supernovae, which have helped us understand the life cycle of stars.
Mapping the Universe
The HST has been used to create detailed maps of the universe, identifying the location and properties of galaxies, clusters, and other large-scale structures. These maps have helped us understand the distribution of matter in the universe and the nature of dark matter, which is believed to make up most of the matter in the universe.
The Legacy of the Hubble Space Telescope
The HST has been in operation for over 30 years, and it has transformed our understanding of the universe. Its discoveries have paved the way for future missions, such as the James Webb Space Telescope, which is set to launch in 2021.
Inspiring Future Generations
The HST has not only contributed to scientific advancement but has also inspired millions of people worldwide. Its stunning images have captured the imagination of people of all ages, sparking an interest in science and technology. It has also been used in education, with teachers using its images to teach students about astronomy and the universe.
Leaving a Lasting Impression
As the HST nears the end of its operational life, it will continue to leave a lasting impression on the scientific community and the public. Its discoveries will continue to shape our understanding of the universe and inspire future generations to pursue a career in science.
