| This NASA/ESA Hubble Space Telescope image captures the barred spiral galaxy NGC 1385 in detail. |
A new image from the NASA/ESA Hubble Space Telescope showcases the barred spiral galaxy NGC 1385, located approximately 30 million light-years away in the constellation Fornax. Though Hubble has previously captured this galaxy, the latest image offers a dramatically different visual impression—highlighting how both technology and technique shape our view of the cosmos.
Unlike an earlier version dominated by cooler blue tones, the updated image glows with warmer pinkish-red and umber hues. This difference in appearance isn’t merely aesthetic; it reflects the specific combination of filters used during image acquisition.
Telescopes like Hubble are equipped with a variety of filters—ranging from broadband filters that allow a wide range of wavelengths, to narrowband filters designed to isolate very specific wavelengths of light. These filters are crucial tools that enable astronomers to study the physical and chemical properties of celestial objects.
By selecting certain filters, researchers can target emissions from particular elements, assess temperatures, pressures, and even the dynamics of star formation within galaxies. In the case of NGC 1385, the use of different filters reveals a richer tapestry of interstellar dust, glowing gas, and stellar activity than seen in the previous image.
This kind of multi-wavelength observation helps astronomers build a deeper understanding of the structure and evolution of galaxies. For scientists and space enthusiasts alike, it’s a reminder of how every shift in perspective—down to the wavelength—can uncover something entirely new.
