- NASA's Chandra X-ray Observatory has identified the likely source of repeated outbursts from a giant, unstable star in the galaxy NGC 4559.
- NGC 4559 is about 30 million light-years from Earth.
- The finding is described as a likely source, not a confirmed one.
Why it matters
Pinning down what drives these outbursts helps astronomers tell such events apart from true supernovae, as the 'supernova impostor' label in one source suggests.
