- Recently, NASA has shared a picture of an open cluster known as NGC 2164 that was captured by the Hubble Space Telescope (HST).
- This image was taken by the NASA/ESA Hubble Space Telescope’s Wide Field Camera 3 (WFC3), which has previously imaged many other open clusters, including NGC 330 and Messier 11.
About NGC 2164
- It was first discovered in 1826 by a Scottish astronomer named James Dunlop.
- It is located within one of the Milky Way galaxy’s closest neighbors — the satellite galaxy is known as the Large Magellanic Cloud.
- Large Magellanic cloud: it is a relatively small galaxy that lies about 160,000 light-years from Earth.
- It is considered a satellite galaxy because it is gravitationally bound to the Milky Way.
Key Points about Hubble Telescope
- It was launched in 1990 into Low Earth orbit by NASA (USA Space Agency) with the contribution and in collaboration with the European Space Agency.
- It is named after the astronomer Edwin Hubble.
- Part of NASA’s Great Observatories Program: Including Hubble Telescope, it is a family of four space-based observatories, each observing the Universe in a different kind of light.
- The visible-light Spitzer Space Telescope,
- Compton Gamma-Ray Observatory (CGRO), and
- The Chandra X-Ray Observatory (CXO).
- The optical light Hubble space telescope
- Key features of the Hubble Telescope:
- It covers the entire Optical spectrum from infrared to ultraviolet.
- It makes one orbit around Earth every 95 minutes.
Important Contributions of the Hubble Telescope
- Helped in discovering the moons around Pluto.
- Evidence regarding the existence of black holes has emerged based on the observations through Hubble.
- The birth of stars through turbulent clouds of gas and dust has also been observed.
- Made observations of six galaxies merging together.
- The Hubble telescope has made observations of small concentrations of black holes.
