When you look up, how far back in time do you see?
Our senses are stuck in the past. There's a flash of lightning, and then seconds pass until we hear the rumble of distant thunder. We hear the past.

Using the Visible and Infrared Survey Telescope for Astronomy (VISTA), astronomers have detected a new bright quasar at a redshift of about 6.8. The newly identified quasar, designated VHS J0411-0907, is the brightest object ...
The path of light is bent by mass, an effect predicted by Einstein's theory of gravity, and when a massive galaxy or cluster lies along our line-of-sight to a more distant galaxy its matter will act as a lens to image the ...

An international team of astronomers has detected a new luminous quasar at a redshift of 7.02. The newly found quasi-stellar object (QSO), designated DELS J003836.10–152723.6, is the most luminous quasar known at a redshift ...
Astronomers report the finding of two new high-redshift quasars using imagery from the Optical Gravitational Lensing Experiment (OGLE). The newly found quasars, designated OGLE J015531−752807 and OGLE J005907−645016, ...
Earlier this year, on a quiet Sunday night, my colleague Jack and I found the fastest-growing supermassive black hole in the known universe. We were fortunate to be part of the team that made one of the greatest discoveries ...

Astronomers have discovered a highly magnified, gravitationally lensed quasi-stellar object (QSO). The newly found quasar, designated W2M J104222.11+164115.3, is dust-reddened, and exhibits a significant flux anomaly. The ...
Carnegie's Eduardo Bañados led a team that found a quasar with the brightest radio emission ever observed in the early universe, due to it spewing out a jet of extremely fast-moving material.

Astronomers have detected two new bright quasars at a redshift of about 5.0. The newly found quasi-stellar objects (QSOs) are among the brightest high-redshift quasars known to date. The finding was presented May 9 in a paper ...
Using Hyper Suprime-Cam (HSC) mounted on the Subaru Telescope, astronomers have identified nearly 200 "protoclusters," the progenitors of galaxy clusters, in the early universe, about 12 billion years ago, about ten times ...
