In 1990, the field of astronomy changed forever with the release of Hubble Space Telescope.Although not the first space observatory But unprecedented resolution and versatility yield the deepest and most detailed images of the universe. The latest image released by the mission features the spiral galaxy NGC 691, taken in stunning detail with Hubble’s Wide Field Camera 3 (WFC3).
This galaxy is approximately 120 million light-years from Earth in the constellation Aries. and a leading member of the gravitational galaxy. The galaxy cluster (called NGC 691) was the first recorded observation of this galaxy by German-British astronomer William Herschel on November 13.th, 1786 Later observations revealed a three-ring structure and measured about 120,000 light-years in diameter.
Like other celestial objects Hubble observed NGC 691 using a multi-range filter that allows the wavelength of light. From ultraviolet and visible to infrared light to WFC3, filtered images are painted by experts who choose colors that represent different wavelengths. best observed While ultraviolet is generally purple and infrared is red. Visible light from stars, gas, and dust is displayed in white-blue.
These processed images are then combined to create full-color images that provide insights into the nature and characteristics of celestial bodies. In the case of NGC 691, the resulting images show the beautiful ring structure of the galaxy. CC Individual ring ripple characteristics and intensely bright Active Galactic Nucleus (AGN) which is a clear indicator of a supermassive black hole (SMBH) at its core.
Decades later, Hubble continues to offer the world the most incredible view of the universe! A number of more advanced observatories will head into space soon. All of which are expected to make some profound discoveries. Yet no one has been able to compete with the game-changing nature of the Hubblewhich came at the right time and laid the foundation for all future missions.
