SDSS J1229+1122 (SDSS J122952.66+112227.8) is a blue supergiant O-type star in the tail of dwarf irregular galaxy IC 3418. It illuminates a nebula clump of gas, and was discovered from the spectrum of the illumination source. The clump of gas resides in a tail caused by ram pressure stripping of gas from the galaxy by the galaxy cluster. It was determined to be a blue supergiant through analysis of its spectrum.

| - SDSS J122952.66+112227.8 atau biasa disingkat SDSS J1229+1122 adalah bintang kelas-O, sebuah bintang super raksasa biru yang hidup di ekor galaksi katai IC 3418, terletak 55 juta tahun cahaya dari Bumi di rasi bintang Virgo . Bintang ini merupakan bintang terjauh yang diketahui hingga saat ini. Ia menerangi gumpalan gas nebula, dan ditemukan dari spektrum sumber penerangan. Gumpalan gas terletak di ekor yang disebabkan oleh tekanan ram pengupasan gas dari galaksi oleh gugus galaksi (Virgo). Ia bertekad menjadi super raksasa biru melalui analisis spektrumnya. Sampai ditemukannya lensa bermata dua bermodel gravitasi pada tahun 2018, itu adalah bintang paling jauh yang diketahui, pada 55x10 ^ tc. Penemuan ini dibuat oleh Drs. dan , menggunakan Teleskop Subaru. Bintang dan galaksi berada di gugus galaksi Virgo. Gumpalan gas yang diterangi bintang disebut sebagai D3 atau , dan terletak di dalam struktur filamen yang disebut sebagai F1 atau . Ekor galaksi dan semua yang ada di dalamnya keluar dari galaksi untuk menjadi , tidak terikat pada galaksi manapun, hanya gugusannya. (in)
- SDSS J1229+1122 (SDSS J122952.66+112227.8) is a blue supergiant O-type star in the tail of dwarf irregular galaxy IC 3418. It illuminates a nebula clump of gas, and was discovered from the spectrum of the illumination source. The clump of gas resides in a tail caused by ram pressure stripping of gas from the galaxy by the galaxy cluster. It was determined to be a blue supergiant through analysis of its spectrum. Until the discovery of the doubly gravitationally lensed MACS J1149 Lensed Star 1 (also known as Icarus) in 2018, SDSS J1229+1122 was the most distant-known star, at 55 million light-years (17 Mpc) (stars more distant than this are only known through events that they cause, such as stellar explosions of supernovae and gamma ray bursts). (The record for the most distant star is, as of June 2017, a strongly lensed star at redshift 1.5 behind the galaxy cluster MACS1149.) The discovery was made by Drs. Youichi Ohyama and Ananda Hota, using the Subaru Telescope. The star and its galaxy are in the Virgo Cluster of galaxies. The clump of gas that the star illuminates is referred to as D3 or IC3418 D3, and lies within a filamentary structure referred to as F1 or IC3418 F1. The galactic tail and all within it are escaping the galaxy to become intracluster flotsam, unattached to any galaxy, just the cluster. (en)
