Rebecca Smethurst, also known as Dr. Becky, is a British astrophysicist, author, and YouTuber who is a Royal Astronomical Society Research Fellow [6] at the University of Oxford. She was the recipient of the 2020 Caroline Herschel Prize Lectureship, awarded by the Royal Astronomical Society, as well as the 2020 Mary Somerville Medal and Prize, awarded by the Institute of Physics. In 2022, she won the Royal Astronomical Society's Winton Award "for research by a post-doctoral fellow in Astronomy whose career has shown the most promising development".
As a researcher, Smethurst studies the role that supermassive black holes play in inhibiting different types of galaxies from forming stars. She is a member of the Galaxy Zoo collaboration, run by her doctoral advisor, Chris Lintott. Smethurst hosts her own YouTube channel, called Dr. Becky, where she posts science communication videos related to astronomy research and amateur astronomy. She has also written two popular science books, titled Space: 10 Things You Should Know and A Brief History of Black Holes.
While growing up, Smethurst attended the Bolton School Girls' Division for a decade, from 1998 through 2008. She received a first-class master's degree in physics and astronomy from the University of Durham in 2012. After taking a year off from academic studies, Smethurst began pursuing a doctoral degree at the University of Oxford, with Chris Lintott as her supervisor. She earned her doctorate in 2017 with a thesis titled "The influence of morphology, AGN and environment on the quenching histories of galaxies". [7] [8]
Smethurst was an Ogden Trust Research Fellow at the University of Nottingham before returning to the University of Oxford in late 2018 as a junior research fellow. [7] [9] She studies the interaction between galaxies and the supermassive black holes at their centres, specifically focusing on if and how these black holes can quench the process of star formation in their surrounding galaxies. Her research involves using statistical methods to analyse large datasets of galaxies obtained through Galaxy Zoo and the Sloan Digital Sky Survey, including the development of several open-source software programs for analytics of large astronomy data sets. [10]
One of her research findings is showing that galaxies in the green valley that do not fit in with normal red elliptical or blue spiral galaxies can be used as a means to probe how and when star formation quenching occurs. [7] [11] [12] Smethurst won the 2020 Caroline Herschel Prize Lectureship, an award given by the Herschel Society through the Royal Astronomical Society, with the goal of "supporting promising female astronomers early in their careers". [11] [13]
Smethurst began creating science communication videos when she was a postdoctoral fellow at the University of Nottingham for the Sixty Symbols YouTube channel, run by Brady Haran and the university's physics department. [4] She also has appeared on Deep Sky Videos, another channel operated by Haran on the theme of astronomy. [14] Smethurst launched her own YouTube channel, eponymously titled Dr. Becky, in late 2018, on which she posts weekly videos related primarily to astronomy research and occasionally on amateur astronomy. [15] These include a monthly series called Night Sky News, in which she discusses events amateurs might observe in the night sky during the month, as well as recent research developments in astronomy. [16] She has also published a book, titled Space: 10 Things You Should Know, which was named one of Sky at Night Magazine's 23 best space and astronomy books of 2019. [14] [17]
Smethurst received the 2020 Mary Somerville Medal and Prize, an award given "for exceptional early career contributions to public engagement in physics", winning specifically for "engaging a diverse, global audience with complex astrophysical ideas presented at an accessible level with a large dose of enthusiasm on the YouTube channel Dr. Becky". [18] [19] Smethurst hosts The Supermassive Podcast together with journalist Izzie Clarke. [5] [20] The show, produced by the Royal Astronomical Society focuses on astronomy and related research. [21]
Sandra Moore Faber is an American astrophysicist known for her research on the evolution of galaxies. She is the University Professor of Astronomy and Astrophysics at the University of California, Santa Cruz, and works at the Lick Observatory. She has made discoveries linking the brightness of galaxies to the speed of stars within them and was the co-discoverer of the Faber–Jackson relation. Faber was also instrumental in designing the Keck telescopes in Hawaii.
Vera Florence Cooper Rubin was an American astronomer who pioneered work on galaxy rotation rates. She uncovered the discrepancy between the predicted and observed angular motion of galaxies by studying galactic rotation curves. These results were later confirmed over subsequent decades. Her work on the galaxy rotation problem was cited by others as evidence for the existence of dark matter. The Vera C. Rubin Observatory in Chile is named in her honor.
Eleanor Margaret Burbidge, FRS (née Peachey; 12 August 1919 – 5 April 2020) was a British-American observational astronomer and astrophysicist. In the 1950s, she was one of the founders of stellar nucleosynthesis and was first author of the influential B2FH paper. During the 1960s and 1970s she worked on galaxy rotation curves and quasars, discovering the most distant astronomical object then known. In the 1980s and 1990s she helped develop and utilise the Faint Object Spectrograph on the Hubble Space Telescope. Burbidge was also well known for her work opposing discrimination against women in astronomy.
Andrea Mia Ghez is an American astrophysicist, Nobel laureate, and professor in the Department of Physics and Astronomy and the Lauren B. Leichtman & Arthur E. Levine chair in Astrophysics, at the University of California, Los Angeles. Her research focuses on the center of the Milky Way galaxy.
Messier 58 is an intermediate barred spiral galaxy with a weak inner ring structure located within the constellation Virgo, approximately 68 million light-years away from Earth. It was discovered by Charles Messier on April 15, 1779 and is one of four barred spiral galaxies that appear in Messier's catalogue. M58 is one of the brightest galaxies in the Virgo Cluster. From 1779 it was arguably the farthest known astronomical object until the release of the New General Catalogue in the 1880s and even more so the publishing of redshift values in the 1920s.
Eugene Newman Parker was an American solar and plasma physicist. In the 1950s he proposed the existence of the solar wind and that the magnetic field in the outer Solar System would be in the shape of a Parker spiral, predictions that were later confirmed by spacecraft measurements. In 1987, Parker proposed the existence of nanoflares, a leading candidate to explain the coronal heating problem.
Christopher John Lintott is a British astrophysicist, author and broadcaster. He is a Professor of Astrophysics in the Department of Physics at the University of Oxford, and, since 2023, Gresham Professor of Astronomy at Gresham College, London.

Red nuggets is the nickname given to rare, unusually small galaxies packed with large amounts of red stars that were originally observed by the Hubble Space Telescope in 2005. They are ancient remnants of the first massive galaxies. The environments of red nuggets are usually consistent with the general elliptical galaxy population. Most red nuggets have merged with other galaxies, but some managed to stay unscathed.
In astronomy, quenching is the process in which star formation shuts down in a galaxy. A galaxy that has been quenched is called a quiescent galaxy. Several possible astrophysical mechanisms have been proposed that could lead to quenching, which either result in a lack of cold molecular gas, or a decrease in how efficiently stars can form from molecular gas.
