Hubble Space Telescope Captures Stunning Image of Distant Galaxy
The Hubble Space Telescope, despite its age, has once again amazed us with a breathtaking photo of a distant galaxy. The latest image showcases the barred spiral galaxy NGC 3059, located approximately 57 million light-years away from Earth.
Released on June 7, the photograph was taken in May using the Wide Field Camera 3 instrument as part of a broader study of galaxies, as detailed in a statement from NASA.
The telescope utilizes a variety of filters for its observations, each allowing specific wavelengths of light to reach its instruments. The recent view of NGC 3059 combines data from narrow and wide-band filters, highlighting pinkish star-forming regions and bluish patches with different stellar populations.
“Narrow-band filters are crucial from a scientific standpoint as they isolate specific wavelengths associated with distinct physical and chemical processes,” explained NASA officials. “For instance, hydrogen atoms can emit red light at 656.46 nanometers, known as H-alpha emission, which is indicative of newly forming stars.”
While narrow-band filters focus on specific wavelengths, wide-band filters capture a broader range of wavelengths, enabling astronomers to study different sections of the electromagnetic spectrum. By combining data from multiple filters, detailed images of cosmic objects like NGC 3059 can be created.
Protecting Hubble’s Future
In recent news, Hubble was placed in a protective “safe mode” to conserve its remaining two functioning gyroscopes, vital for orienting the telescope and targeting celestial objects. Currently operating with only one gyro, the decision aims to extend the telescope’s lifespan, ensuring it continues to provide captivating views of the universe for years to come.
