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).
When observing our closest neighbouring stars, astronomers quickly realised that our Sun stands out from its peers of similar age, possessing a notably greater metallicity.
Transients are a broad class of events, referring to observations where some measurable change occurs, typically in brightness, over relatively short timescales.
