- Measures 43.5 feet (13.2 meters) in length, about the size of a large school bus.
- Weighs around 24,500 pounds (11,110 kilograms).
- Equipped with a 7.9-foot (2.4-meter) primary mirror.
- Uses solar panels to generate power, producing about 2,800 watts.
Scientific Instruments
Hubble is equipped with various instruments that allow it to capture detailed images and data across different wavelengths.
- The Wide Field Camera 3 (WFC3) captures images in ultraviolet, visible, and near-infrared light.
- The Advanced Camera for Surveys (ACS) helps study the formation and evolution of galaxies.
- The Cosmic Origins Spectrograph (COS) analyzes the light from distant stars and galaxies.
- The Space Telescope Imaging Spectrograph (STIS) studies black holes and other cosmic phenomena.
Major Discoveries
Hubble has made numerous groundbreaking discoveries that have deepened our understanding of the cosmos.
- Confirmed the existence of supermassive black holes at the centers of galaxies.
- Provided evidence for the accelerating expansion of the universe.
- Helped determine the age of the universe to be approximately 13.8 billion years.
- Discovered that nearly every major galaxy is anchored by a black hole.
Stunning Images
The telescope has captured some of the most breathtaking images of space, inspiring both scientists and the public.
- The Pillars of Creation, a stunning image of star-forming regions in the Eagle Nebula.
- The Hubble Deep Field, revealing thousands of galaxies in a tiny patch of sky.
- The Horsehead Nebula, showcasing the beauty of interstellar clouds.
- The Crab Nebula, a remnant of a supernova explosion.
Servicing Missions
Hubble has undergone several servicing missions to upgrade its instruments and extend its lifespan.
- Five servicing missions were conducted by NASA astronauts between 1993 and 2009.
- The first mission in 1993 corrected a flaw in the primary mirror.
- The final mission in 2009 installed the Wide Field Camera 3 and repaired other instruments.
- Each mission involved complex spacewalks and precise engineering.
