In recent years, observations of our nearest galactic neighbour, Messier 31 (M31) or the Andromeda galaxy, have identified that the system has undergone a tumultuous history.

One of the key questions in modern cosmology is determining the precise value of the Hubble parameter (H₀), which describes the linear relationship between an object's recession velocity and its distance.

A team has investigated over 26,000 white dwarfs, confirming the predicted trend that hotter white dwarfs are slightly puffier than cooler ones, even at the same mass.

The solar system lies embedded within a sparse region of the interstellar medium 1000 lyr across, known as the local bubble.
