A supernova, pinpointed by amateur astronomers, could reveal unexpected new steps in the deaths of massive stars.

A supernova that recently exploded in the Pinwheel Galaxy has revealed hitherto unknown information about the final days of the star that exploded.

SN 2023ixf, a Type II supernova discovered in May 2023, challenges conventional understanding with its unprecedented mass loss, shedding light on stellar evolution mysteries.

This supernova could prove a lynchpin in our understanding of the deaths of massive stars.

A newly discovered nearby supernova whose star ejected up to a full solar mass of material in the year prior to its explosion is challenging the standard theory of stellar evolution. The new observations are giving astronomers new insight into what happens in the final year prior to a star’s death and explosion.

The curvature of space-time around a colossal mass has yielded the most detailed measurement of the cosmic distribution of dark matter yet.

This galaxy, named 9io9, is situated at such an immense distance that its light has traveled for over 11 billion years before reaching the Earth.

Operations at both the North and South Gemini telescopes have been temporarily suspended following a cybersecurity incident.
