Scientists studying one of the earliest known galaxies using the James Webb Space Telescope have found that the universe's ...

Learn about a new observation of a galaxy emitting ultraviolet light that broke through the early universe's dense fog.

By analyzing the data from Leahy's atlas of double radio-sources and NASA/IPAC Extragalactic Database (NED), Serbian ...

GS-z13-1, marks the earliest sign yet spotted of the era of cosmic reionization at 330 million years after the Big Bang.

It can observe at redder wavelengths than its predecessor, the Hubble Space Telescope, and it has extended the frontier of galaxy detection to less than 300 million years since the Big Bang 3.

Redshift is also the name of the factor z indicating the relative change in wavelength due to the Doppler shift for a receding galaxy. The Doppler equation used for sound calculations cannot be ...
