A “nova” has been created in the constellation Lupus by an unexpected explosion in the Milky Way – and it can now be seen with the naked eye from parts of North America.

On June 12, astronomers with the All-Sky Automated Survey for Supernovae at Ohio State University first spotted the new point of light, which at the time had an apparent magnitude of +8.7 but was still too dim to see without the naked eye, as originally reported by Sky & Telescope. (A lower magnitude indicates a brighter object; the Moon, for example, has an apparent magnitude of -12.7.)

Over the next few days, the rapidly brightening object adopted several temporary names, including AT 2025nlr, ASASSN-25cm, and N Lup 2025, as researchers tried to establish its identity.
