A newly identified quasar and a dwarf planet once nicknamed 'The Goblin' have new, official names derived from Hawaiian traditions.

Double quasar 0957+561 was the first confirmed case of gravitational lensing. ... If it were true, it would be the farthest-ever planet in the cosmos. So, getting back to QSO 0957+561, ...

Colossal Quasar Clump Too Huge To Exist, ... Basically, it's sort of like one planet per star. And because we think there is around 100 billion stars in our whole galaxy, ...

To give some idea of the luminosity of a quasar, scientists at the Mullard Space Science Laboratory at University College London describe how the nearest quasar, 3C 272, has a luminosity of 2.5 x ...

Astronomers have detected an intensely brightening and dimming quasar that may help explain how some objects in the early universe grew at a highly accelerated rate. The discovery is the most ...

This is, far and away, the longest such jet ever observed emanating from a quasar seen from the first billion years after the Big Bang. The previous record-holder had a jet just 5,000 light-years ...

Astronomers first discovered quasars, the brightest and most powerful objects in the universe, 60 years ago. Now, scientists think they have unlocked the mystery behind what ignites these ...

This quasar, known as RX J1131-1231, is about 6.1 billion light-years away, much too far to be studied at high resolution under ordinary circumstances.

A quasar that close could have caused a lull in star formation that astronomers might someday detect by measuring precise ages for our galaxy’s oldest stars (SN: 3/23/22).
