The image was captured using Spitzer's Infrared Array Camera and the Multiband Imaging Photometer.
The H4RG-10 infrared array is at a mature state, advanced to NASA technology readiness level 6 (TRL-6) during a 45-month development contract that commenced in 2014.
The discovery, reported in the journal Nature Astronomy, was done using Spitzer's Infrared Array Camera to observe the planet while it completed an orbit around its host star.

At the heart of this new passive infrared array is a thermopile IR detector chip, which consists of 64 thermopile elements arranged in an 8x8 format, A built-in thermistor and ASIC chip round out the electronics.
At present VOx (vanadium oxide) microbolometer arrays are the most used technology for uncooled detectors, which are produced in larger volumes than all other infrared array technologies put together, and this trend is expected to increase in the near future for both military and civilian applications.
Images captured on June 13 with Spitzer's Infrared Array Camera indicate carbon dioxide is slowly and steadily "fizzing" away from the so-called "soda-pop comet," along with dust, in a tail about 186,400 miles long.
A few years later, new infrared array detectors marked a further breakthrough.
Further, it provides accurate measurements of the masses of these clusters, which are crucial to unraveling the nature of dark energy.The main goal of the SPT survey is to find a large sample of massive galaxy clusters in order to measure the equation of state of the dark energy, which characterizes cosmic inflation and the accelerated expansion of the universe.Additional goals include understanding the evolution of hot gas within galaxy clusters, studying the evolution of massive galaxies in clusters, and identifying distant, gravitationally lensed, rapidly star-forming galaxies.Once this distant cluster was found, the team studied it with the Infrared Array Camera on the Spitzer Space Telescope to pinpoint galaxies within the cluster.
An even higher level of security can be obtained using the company's no-tailgating protection, which works with an infrared array and camera that sends an alarm and pictures of the user and tailgater to the system's command center software.
Interestingly, since infrared waves can be collected by normal telescopes and infrared signals are much less affected by light pollution from nearby cities, many older observatories received a new lease of life with the advent of infrared array detectors that can be retrofitted onto the older observatories.
The performance of an infrared array is degraded by any lack of uniform response from pixel to pixel.
