# To measure a black hole's spin, we need to go to space Astronomers are developing a new tool to understand black hole spin rates. - **Source:** [Phys.org - latest science and technology news stories](https://brifing.si/source/8b0f98da-d179-4c93-871f-7ac460bf9c61) - **Published:** 2026-07-16 - **Topic:** [Business](https://brifing.si/c/business) - **Original article:** - **On Brifing:** https://brifing.si/s/337a868b-b19c-4569-af0b-ed8ad51960de ## The mysterious spin of black holes Black holes don't just consume matter; they also spin at incredible speeds. This spin rate profoundly affects how they warp spacetime and influence galaxy evolution. For astronomers, measuring this spin provides crucial clues about the universe's workings. ## Limitations of current technology Currently, we can't measure the actual spin rate of black holes. Earth-based observations are insufficient to fully understand these massive objects. Atmospheric interference and technological constraints make precise measurements challenging. ## A new hope: Space-based instruments Tegan Thomas from the University of Virginia and her team are developing a new space-based tool that could be operational in the coming years. This instrument will have the capacity to directly measure black hole spin rates, providing astronomers with more accurate data about these enigmatic objects. ## Black holes' role in galaxy evolution The spin rate of black holes plays a critical role in shaping surrounding galaxies. High spin rates influence star formation and matter distribution in galactic centers. Understanding these spins is vital for refining galaxy evolution models. ## Challenges to scientific progress Developing space-based observation tools is time-consuming due to high costs and technical difficulties. However, such projects are essential for solving the universe's greatest mysteries. Astronomers hope new technologies will reveal more about black holes. ## The significance of future discoveries Measuring black hole spin rates will be a major step not only in astronomy but also in testing general relativity. Such discoveries will open new horizons in humanity's quest to understand the universe and contribute to our scientific knowledge. ## Sources covering this story - https://phys.org/news/2026-07-black-hole-ultimate-space.html — --- _Summary written by Brifing from the original reporting.
