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).
So if the matter that originally emitted the oldest CMBR photons has a present distance of 46 billion light-years, then the distance would have been only about 42 million light-years at the time of decoupling. The light-travel distance to the edge of the observable universe is the age of the universe times the speed of light, 13.8 billion light ...
For comparisons with the light travel distance of the astronomical objects listed below, the age of the universe since the Big Bang is currently estimated as 13.787±0.020 Gyr. [1] Distances to remote objects, other than those in nearby galaxies, are nearly always inferred by measuring the cosmological redshift of their light. By their nature ...
But data collected by the Webb telescope showed that UHZ1 is actually much farther away and located beyond the cluster at 13.2 billion light-years from Earth. A light-year, equivalent to 5.88 ...
Scientists were ‘surprised’ to find a star that is much farther than the previous record-holder, which was nine billion light years away. Star 13 billion light years from Earth is most distant ...
LAE J095950.99+021219.1 is about 13 billion light years away and is among the most-distant known objects in the universe. It is a Lyman-alpha emitter. [1] LAE J095950.99+021219.1 was discovered in mid-2012. It was observed using the Magellan Telescopes at the Las Campanas Observatory in Chile. LAE J095950.99+021219.1 is emitting light ...
Spectroscopic observations by JWST's NIRSpec instrument in October 2022 confirmed the galaxy's redshift of z = 13.2 to a high accuracy, establishing it as the oldest and most distant spectroscopically-confirmed galaxy at the time, with a light-travel distance (lookback time) of 13.4 billion years.
HD1 is one of the earliest and most distant known galaxies yet identified in the observable universe, having a spectroscopic redshift of z = 13.27, meaning that the light from the galaxy travelled for 13.5 billion years on its way to Earth, which due to the expansion of the universe, corresponds to a proper distance of approximately 33.4 billion light-years (10.2 billion parsecs).
