An image from the Hubble Space Telescope showcases the barred spiral galaxy NGC 1385, situated around 30 million light-years away. This image is credited to ESA/Hubble & NASA, R. Chandar, J. Lee, and the PHANGS-HST team.
Two contrasting images of the barred spiral galaxy NGC 1385, captured by the Hubble telescope, demonstrate the impact of utilizing various specialized filters.
The image reveals the luminous cluster of stars and cosmic dust forming the barred spiral galaxy NGC 1385, positioned about 30 million light-years from our planet. Previously, the galaxy was featured in a different Hubble Picture of the Week (refer to the image below), showcasing a distinct appearance. The newer image displays a palette rich in pinkish-red and brown tones, in contrast to the previous image’s cooler blue hues. This color variation is not merely artistic but stems from the technical application of different filters in gathering the data for these images.

Understanding Telescope Imaging Methods
It might be puzzling to see how the same galaxy, captured twice by the Hubble telescope, can be presented so differently in two separate images.
The explanation lies in the fact that the Hubble, like other advanced telescopes used in scientific research, is equipped with a variety of filters. These filters are vastly different from those used in social media applications, which are applied post-capture and often lead to loss of information as they emphasize or suppress certain colors for visual appeal.
Telescope filters, on the other hand, are physical components that selectively allow specific light wavelengths to pass through during data collection. This selective process does result in some light loss, but it enables astronomers to focus on precise segments of the electromagnetic spectrum. This is crucial for various scientific purposes, such as identifying physical processes in certain elements that emit light at specific wavelengths, allowing for the optimization of filters to these frequencies.

Frequently Asked Questions (FAQs) about Hubble Galaxy Imaging
What is the significance of the Hubble Space Telescope images of NGC 1385?
The Hubble Space Telescope images of NGC 1385 showcase the galaxy in different lights, due to the use of specialized filters. These images reveal the barred spiral galaxy’s structure and color variations, emphasizing the importance of telescope filters in astronomical research.
How do the filters used by Hubble differ from social media filters?
Unlike social media filters that are applied post-capture and often alter or lose image data for aesthetic purposes, Hubble’s filters are physical components that selectively allow specific wavelengths of light during data collection. This method enables precise scientific analysis of celestial objects.
Why are different colored images of NGC 1385 important in astronomy?
Different colored images of NGC 1385, resulting from various filters, are crucial in astronomy as they allow scientists to examine specific parts of the electromagnetic spectrum. This helps in understanding the physical processes and elements within the galaxy, offering insights into its composition and behavior.
Can the same galaxy appear different in images taken by the same telescope?
Yes, the same galaxy can appear different in images taken by the same telescope, like Hubble, due to the use of different filters. Each filter allows astronomers to capture and study different wavelengths of light, resulting in varied color representations in the images.

This is fascinating, but the article seems a bit technical for beginners, maybe simplify it a bit next time? just a thought.
hubble does it again! amazing how they capture these images, but the article could explain a bit more about how these filters work??
gotta love those images, NGC 1385 looks stunning, but there’s a typo, should be “light-years” not “light years”, right?
wow, this is so cool, didn’t know that the same galaxy can look so different just because of filters.
the comparison between telescope and social media filters is interesting, never thought of it that way before. good job on that part.
