Blasts through space at 30% the speed of light have been observed in a distant quasar. This record-breaking ultraviolet wind from J2318 provides new clues about black hole-galaxy interactions and cosmic evolution.
Researchers at York University identified the fastest ultraviolet wind ever detected near a supermassive black hole. This outflow originates from quasar J2318, reaching speeds that challenge current theoretical models of cosmic particle survival.
This billion-solar-mass engine launches gas at 90,000 kilometres per second. Observed via the Gemini North telescope, the discovery suggests black holes play a violent role in heating gas and redistributing galactic material.
Understanding blasts through space at 30% the speed of light
Blasts through space at 30% the speed of light are extreme ultraviolet outflows from quasars like J2318. These relativistic winds, accelerated by intense radiation pressure, regulate galaxy growth by disrupting star formation and redistributing energy across vast intergalactic distances.
Quasars are incredibly bright galactic centres powered by gas spiraling into supermassive black holes. As matter falls inward, intense radiation pushes some gas outward at speeds resembling category 79 hurricanes.
Observations from the Sloan Digital Sky Survey initially flagged J2318. Subsequent verification using the Gemini North telescope in Hawai’i confirmed the wind’s record velocity, marking it the fastest ultraviolet outflow ever seen.
The relativistic wind of J2318
A relativistic wind blasts through space at 30% the speed of light, launched by a black hole 1.7 billion times more massive than the Sun. Located in the constellation Pegasus, J2318 emits ultraviolet light that allows astronomers to track carbon and silicon ions moving at these extreme velocities.
Ultraviolet records and Sloan survey data
Although X-ray winds can be faster, J2318 holds the current ultraviolet record. This breakthrough resulted from undergraduate researchers analyzing Sloan Digital Sky Survey spectra to spot unusual galactic outflows while mapping the most distant reaches of the universe.

Scientific importance and theories
Scientists theorize that radiation pressure from quasar photons provides the pushes required for acceleration. The fact that a wind blasts through space at 30% the speed of light while keeping ions intact remains a puzzle, as intense radiation typically strips electrons away.
Galactic feedback and evolutionary impact
A powerful outflow that blasts through space at 30% the speed of light acts as a missing link in galactic feedback. These winds heat surrounding gas, which effectively halts star formation and helps astronomers understand how central black holes shape host galaxies.
Discovery of rare cosmic engines
- J2318 represents a “Fast and Furious” family of rare, luminous quasars.
- Astronomers used the 8-metre Gemini North telescope for velocity verification.
- Multi-wavelength observations are required to find even faster ultraviolet outflows.
- Future surveys from the nearby universe to deep space continue the search.
Implications and what comes next
Identifying an outflow that blasts through space at 30% the speed of light forces cosmologists to refine their feedback simulations. This ensures that models correctly represent how matter redistributes through the intergalactic medium.
Researchers are now hunting for additional extreme winds across the universe. While J2318 is rare, studying its unique environment helps scientists probe the absolute limits of black hole power and gravitational influence.
Conclusion
This record-breaking ultraviolet discovery demonstrates the incredible power of supermassive black holes. Any wind that blasts through space at 30% the speed of light serves as a transformative force in the cosmos. Explore more space news on our YouTube channel—join NSN Today.
