August 23, 2022 - The Earth has been expanding away from the emitted light, increasing the travel time. ... "It originated from the direction of the constellation Sagitta, and traveled an estimated 1.9 billion years to reach Earth -- less than the current distance of its starting point, because the universe is expanding."

February 28, 2024 - Astronomers have found the brightest known object in the universe—a glowing core of a galaxy, called a quasar, located 12 billion light-years away. Quasars, as a whole, are the brightest objects in the cosmos, each consisting of a supermassive ...

November 21, 2019 - Known as GRB 190114C, some of the light detected from the object had the highest energy ever observed: 1Tera electron volt (TeV) — about one trillion times as much energy per photon as visible light.

June 9, 2020 - “It’s a trillion times more energetic than visible light,” says co-author Gemma Anderson, from the Curtin University, Australia, node of the International Centre for Radio Astronomy Research. “It makes GRB 190114C the brightest known ...

February 21, 2024 - The brightest known object in the universe, a quasar 500tn times brighter than our sun, was “hiding in plain sight”, researchers say. Australian scientists spotted a quasar powered by the fastest growing black hole ever discovered.

February 21, 2024 - Astronomers have discovered the most luminous object ever detected, a quasar 12 billion light-years away that's 500 trillion times more luminous than the sun.

1 week ago - Although quasars appear faint when viewed from Earth, they are visible from extreme distances, being the most luminous objects in the known universe. The brightest quasar in the sky is 3C 273 in the constellation of Virgo.

September 27, 2019 - Astronomers have discovered the ... hole ravenously eating material surrounding it, and it shines with the light of 600 trillion suns....

October 16, 2023 - Nicknamed the “BOAT” (Brightest Of All Time), satellite-mounted instruments recorded a peak of 6.5 million gamma ray photons per second coming from the distant object, each carrying an energy of 18 teraelectronvolts – or around two times the power than the Large Hadron Collider can impart ...

November 29, 2019 - An international team of astrophysicists has detected two massive gamma-ray bursts, the most powerful and violent events in the universe that can outshine a supernova by hundreds of times and even emit more energy in 10 seconds than the Sun will release in its lifetime1.

November 21, 2019 - On January 14, the Major Atmospheric Gamma Imaging Cherenkov observatory in the Canary Islands captured the highest-energy light ever recorded from a gamma-ray burst. This illustration of that event also shows NASA's Fermi and Swift spacecraft ...

Luxor Lamp in Las Vegas, the world's brightest light, illuminates the night sky with 42.3 billion candela. Discover its power and ecological impact.

January 11, 2019 - Scientists have discovered the energetic core of a distant galaxy that shatters the record for the brightest object in the early universe, blazing with the light equivalent to 600 trillion suns.

June 13, 2025 - Quasars become so bright that their cores will outshine all the stars in their disk, making them the brightest objects in the sky and visible from billions of light-years away. As a general rule, astronomers gauge the growth rate of SMBHs based on the luminosity of their galaxy's core region - the brighter the quasar, the faster the black hole is accreting matter.

This artist’s impression shows the record-breaking quasar J059-4351, the bright core of a distant galaxy that is powered by a supermassive black hole.
