Context: The Hubble Space Telescope has revealed an intermediate-mass black hole within the Omega Centauri star cluster in the Milky Way galaxy
Omega Centauri:
- Largest and Most Luminous: Omega Centauri (NGC 5139 or Caldwell 80) is the Milky Way’s largest and brightest globular cluster, containing millions of stars within a diameter of approximately 150 light-years.
- Visibility: Located about 17,000 light-years from Earth, Omega Centauri is visible to the naked eye.
Black Holes:
- Characteristics: Black holes are regions of space with extremely dense matter and a powerful gravitational pull, which even light cannot escape. Due to their nature, they are invisible to telescopes and can only be studied based on their effects on surrounding matter.
- Properties: Known for their extreme density and ability to warp space and time, black holes are studied through their influence on nearby objects and light.
Hubble Space Telescope:
- Launch and Collaboration: An astronomical observatory launched in 1990 by NASA in collaboration with the European Space Agency (ESA).
- Naming: Named after Edwin Hubble, whose research in the 1920s provided the first evidence of the universe’s expansion.
- Orbit and Instruments: The telescope orbits about 547 kilometers above Earth and features a 2.4-meter primary mirror along with advanced scientific instruments. These tools enable it to capture high-resolution images and spectroscopic data across the electromagnetic spectrum.
- Mission: The primary objectives of the Hubble Space Telescope include exploring the universe and studying its composition, formation, and evolution.
