Hubble used two devices to picture this stunning galaxy

Posted on

This week’s picture from the Hubble Area Telescope is placing: The gorgeous galaxy NCG 1097, as captured utilizing two of Hubble’s devices working in tandem. This barred spiral galaxy is situated 48 million light-years away, within the constellation of Fornax, and has a twisted form brought on by gravitational interactions with a close-by companion galaxy referred to as NCG 1097A.

This explicit galaxy is thought for being the positioning of a minimum of three supernovas over the previous twenty years, with stars exploding in epic occasions after they reached the ends of their lives. The supernovas have been referred to as SN 1992bd, SN 1999eu, and SN 2003B, named for the years of their observations.

This picture of NGC 1097 was taken utilizing two of Hubble’s devices, the Huge Area Digicam 3 (WFC3) and the Superior Digicam for Surveys (ACS). To create this one picture, each devices have been used to look at the identical goal, then information from each have been mixed to create the picture.

“The concept that two totally different cameras can take a single picture is just not very intuitive,” Hubble scientists clarify. “Nonetheless, it makes way more sense after delving into how stunning astronomical pictures like this are composed. Our eyes can detect gentle waves at optical wavelengths between roughly 380 and 750 nanometers, utilizing three forms of receptors, every of which is delicate to only a slice of that vary. Our mind interprets these particular wavelengths as colours. Against this, a telescope digital camera just like the WFC3 or ACS is delicate to a single, broad vary of wavelengths to maximise the quantity of sunshine collected. Uncooked pictures from telescopes are at all times in grayscale, solely exhibiting the quantity of the sunshine captured throughout all these wavelengths.”

Each the WFC3 and ACS have been used to picture within the galaxy particularly wavelengths, as managed utilizing filters. Every filter is used to have a look at a selected wavelength similar to a sure coloration and produces a greyscale picture. Then a complete of seven of those filtered pictures have been mixed to supply the picture as seen above.
