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.

Relative to solar-system timescales, Saturn’s rings are believed to be quite young, estimated to be only 100–400 million years old. This estimate is based on the remarkable purity of the material composing the rings.

Season’s Greetings, Everyone! I hope that, so far, you’ve all had a wonderful holiday season, filled with joy, relaxation, and maybe even some clear skies for stargazing! 

In our galaxy, an estimated 40% of stars are members of binary systems, which are often embedded within a circumbinary dust disks.

Astronomers have taken the first close-up picture of a star outside of the milky way. WOH G64, also known as the “behemoth star” has been imaged using the European Southern Observatory’s Very Large Telescope (ESO’s VLT).
