The Hubble Space Telescope captured this image of the barred spiral galaxy NGC 3059, which lies about 57 million light-years from Earth, in May 2024.NGC 3059, which lies about 57 million light-years from Earth. The photo, released on June 7, was taken in May using the space telescope's Wide Field Camera 3 instrument as part of a broader galactic study, according tofor its observations, each of which allows specific wavelengths of light to pass through to the telescope's instruments.
"For example, under certain conditions, hydrogen atoms emit red light with a wavelength value of 656.46 nanometers called H-alpha emission, or the 'H-alpha line,'" they added."It is very useful to astronomers because its presence indicates certain physical processes and conditions and is often a tell-tale sign of newly forming
H-alpha emissions are observed using narrow-band filters, whereas wide-band filters capture a wider range of wavelengths and allow astronomers to isolate sections of the electromagnetic spectrum.
