Monthly Notices of the Royal Astronomical Society (MNRAS) is a peer-reviewed scientific journal covering research in astronomy and astrophysics. It has been in continuous existence since 1827 and publishes letters and papers reporting original research in relevant fields. Despite the name, the journal is no longer monthly, nor does it carry the notices of the Royal Astronomical Society The first issue of MNRAS was published on 9 February 1827 as Monthly Notices of the Astronomical Society of London and it has been in continuous publication ever since. It took its current name from the second volume, after the Astronomical Society of London became the Royal Astronomical Society (RAS). Until 1960 it carried the monthly notices of the RAS, at which time these were transferred to the newly established Quarterly Journal of the Royal Astronomical Society (1960–1996) and then to its successor journal Astronomy & Geophysics (since 1997). Until 1965, MNRAS was published in-house by the society; from 1965 to 2012 it was published by Blackwell Publishing (later part of Wiley-Blackwell) on behalf of the RAS. From 2013, MNRAS is published by Oxford University Press (OUP). The journal is no longer monthly, with thirty-six issues a year divided into nine volumes. The Letters section had originally appeared on pink paper in the print edition, but moved online only in the early 2000s. Print publication ceased after the April 2020 volume, during the COVID-19 pandemic, with the journal becoming online-only. The stated policy of the RAS is "to focus on high quality papers through rigorous peer review and, as far as practicable, to provide free publication". Authors are not charged for publishing in MNRAS, with the costs of publications being met by subscriptions. MNRAS provides a form of open access by providing authors with the option to pay for publication,
