SPT0615-JD is a dwarf galaxy situated within the constellation Pictor, and is the farthest galaxy ever imaged by means of gravitational lensing, as of 2018.[1][3] Brett Salmon of the Space Telescope Science Institute in Baltimore was the lead scientist of the study of the galaxy.[2]
The galaxy was identified in the Hubble Space Telescope Reionization Lensing Cluster Survey (RELICS) and companion S-RELICS Spitzer program and is at the limits of Hubble's detection capabilities.[2] As a consequence of the effect of a gravitational field of a galaxy cluster of an extremely large size,[2] SPT-CL J0615-5746, (abbreviated to SPT0615),[1] situated at a distance closer to Earth, light from SPT0615-JD located at a further distance, is amplified and distorted (lensed – Einstein 1936; Khvolson 1924; Link 1936) on its motion to the Hubble telescope. This distortion causes the light from the galaxy to arrive as an image lengthened to an arc of about 2 arcseconds long.[2]
"JD" is short for "J-band Dropout" (the galaxy is not detected in the so-called J-band (F125W)[4] The observed image is of 13.3 billion years ago, indicating the galaxy existed when the universe was about only 500 million years in existence.[2] The galaxy is less than 2,500 light-years across.[2]
