A new star, S301, has been discovered orbiting the Milky Way's supermassive black hole at a record-breaking speed, making it the closest and fastest-moving star ever observed.
Imagine a star that's moving really, really fast around a big black hole in the middle of our galaxy. It's so fast that it's moving faster than anything else we've seen before. And it's also very close to the black hole, which makes it easier for scientists to study how the black hole affects the star.

{"heading_1":"The Discovery of S301","subheading_1":"S301's Speed and Proximity","content_1":"S301 is the fastest-moving star ever observed, reaching speeds of approximately 55.8 million miles per hour. It is also the closest star to the Milky Way's supermassive black hole, Sagittarius A*, at a distance of 10 times closer than the previous closest star, S2.","subheading_2":"The Lense-Thirring Effect","content_2":"S301 is so close to Sagittarius A* that it can feel the effects of the black hole's rotation, including the Lense-Thirring effect. This effect, predicted by Einstein's general relativity theory, causes spacetime to be distorted by the black hole's rotation, allowing researchers to study the frame-dragging effect.","subheading_3":"Challenges in Studying S301","content_3":"Despite its proximity, S301 is extremely dim, making it difficult to observe. Researchers used a combination of instruments, including the Gravity instrument on the Very Large Telescope and the Micado instrument on the Extremely Large Telescope, to detect S301."}
Key points
- S301 is the fastest-moving star ever observed
- It is 10 times closer to the Milky Way's supermassive black hole than the previous closest star
- It can feel the effects of the black hole's rotation, including the Lense-Thirring effect
- Researchers used a combination of instruments to detect S301
- It is extremely dim, making it difficult to observe
By studying S301, scientists hope to learn more about how black holes work and how they affect nearby objects. This could lead to new discoveries and a better understanding of these fascinating celestial bodies.
However, studying S301 is challenging because it's so dim and close to the black hole. Any errors in the measurements could lead to incorrect conclusions about the behavior of black holes.
