Astrobites is a blog run by postgraduate students, which aims to make astronomy more accessible and approachable for undergraduates and astronomy enthusiasts. Our daily posts summarise cutting-edge research papers in clear, concise “bites”, reaching tens of thousands of visitors each month, and amassing over 750,000 views in 2020. As well as presenting contemporary research, we publish “Beyond” posts, covering topics including careers advice, commentaries on classic astronomy papers, and other astronomy news. Astrobites also takes an active role in promoting diversity within the field, such as through our #BlackInAstro series of posts, highlighting the contributions and experiences of Black astronomers. Using the Astrobites platform we aim to broaden our reach, and continue making astronomy and astrophysics as accessible as possible to everyone, regardless of their experience or background.
