These were the most remote objects discovered at the time. The pair of galaxies were found lensed by galaxy cluster CL1358+62 (z = 0.33). This was the first time since 1964 that something other than a quasar held the record for being the most distant object in the universe. [135] [138] [139] [136] [133] [140] PC 1247–3406: Quasar 1991 − ...
The objects emitted large amounts of radiation of many frequencies, but no source could be located optically, or in some cases only a faint and point-like object somewhat like a distant star. The spectral lines of these objects, which identify the chemical elements of which the object is composed, were also extremely strange and defied explanation.
Astronomers have spied a monster radio jet in the distant universe that’s twice the width of the Milky Way galaxy. The ancient object formed when the universe was less than 10% of its current ...
Nasa’s James Webb Space Telescope has found the two most distant galaxies ever seen, the space agency has said. The two galaxies are the earliest ever seen in the universe, dating back to when ...
Given the distance between Earth and the objects from the early days of the universe, when telescopes like Webb observe light from the distant cosmos, it’s effectively like looking into the past.
In 1964 a quasar became the most distant object in the universe for the first time. Quasars would remain the most distant objects in the universe until 1997, when a pair of non-quasar galaxies would take the title (galaxies CL 1358+62 G1 & CL 1358+62 G2 lensed by galaxy cluster CL 1358+62 ).
Up until the discovery of JADES-GS-z13-0 in 2022 by the James Webb Space Telescope, GN-z11 was the oldest and most distant known galaxy yet identified in the observable universe, [7] having a spectroscopic redshift of z = 10.957, which corresponds to a proper distance of approximately 32 billion light-years (9.8 billion parsecs).
Scientists have spotted mysterious, incredibly bright objects in the distant universe. New research confirms that there are luminous red objects in the early cosmos – and that they cannot be ...
