Hakeem Muata Oluseyi [1] (born James Edward Plummer Jr.; [2] March 13, 1967) [3] [4] is an American astrophysicist, cosmologist, inventor, educator, science communicator, author, actor, veteran, and humanitarian.
Hakeem Oluseyi was born James Edward Plummer Jr. [1] [5] in New Orleans, Louisiana. After his parents divorced when he was four years old, he and his mother moved to a different state along the southern border of the US every year. He lived in some of the country's toughest neighborhoods including the 9th Ward of New Orleans; Watts, Los Angeles, California; Inglewood, California; South Park, Houston, Texas; and Third Ward, Houston, Texas before settling in rural Mississippi a month before Oluseyi turned 13 years old. He completed middle school and high school in the East Jasper School District graduating as his high school's valedictorian in 1985. Oluseyi served in the U.S. Navy from 1984 to 1986. He credits the Navy with teaching him algebra. [1]
After leaving the Navy with an honorable discharge due to a skin condition from which he had suffered since he was a child, Oluseyi enrolled in Tougaloo College where he earned Bachelor of Science degrees in physics and mathematics. In 1991, he became a graduate student at Stanford University. He earned an M.S. degree in physics in 1995. [1] He changed his name to Hakeem ("wise" in Arabic) Muata ("he who speaks the truth" in Swahili) Oluseyi ("God has done this" in Yoruba) in 1996. [1] Oluseyi earned his Ph.D. degree in physics from Stanford in 1999 [1] [6] under the mentorship of Arthur B. C. Walker Jr., from whom he learned experimental space research. Under Walker's tutelage, Oluseyi helped to design, build, calibrate, and launch the Multi-Spectral Solar Telescope Array (MSSTA), which pioneered normal incidence extreme ultraviolet and soft x-ray imaging of the Sun's transition region and corona. Oluseyi is a member of Kappa Alpha Psi.
From 1999 to 2001 he worked on semiconductor research at Applied Materials. From 2001 to 2004 he was a research fellow at Lawrence Berkeley National Laboratory, working on the Dark Energy Camera and Vera C. Rubin Observatory. [7]
From 2007 to 2019, he was on the faculty of the Florida Institute of Technology in the departments of Physics and Space Sciences. His academic rank was distinguished research professor. [6] From 2016 to 2019. he was stationed at NASA Headquarters in Washington DC where he was the Space Sciences education manager for NASA's Science Mission Directorate via the Intergovernmental Personnel Act Mobility Program. [6] [8] Oluseyi was named a Visiting Robinson Professor at George Mason University in 2021, a distinction by which the university recognizes outstanding faculty. [9]
In 2021, he published an autobiography titled: A Quantum Life: My Unlikely Journey from the Street to the Stars co-authored with Joshua Horwitz. [7] As of 2022, Oluseyi is the president of the National Society of Black Physicists. [10]
His best known scientific contributions are research on the transfer of mass and energy through the Sun's atmosphere; the development of space-borne observatories for studying astrophysical plasmas and dark energy; and the development of technologies in ultraviolet optics, [11] [12] [13] [14] detectors, [15] [16] [17] [18] computer chips, [19] [20] [21] [22] and ion propulsion. [23]
In 2021, Oluseyi carried out an investigation into the role that former NASA administrator James Webb played in the Lavender Scare of the 1950s and 1960s, after a number of scientists and journalists had raised concerns about the naming of NASA's new space telescope after him. Contrary to the claims of Webb's critics, Oluseyi found there was no evidence that Webb was implicated. [24] His finding was later confirmed by a full report carried out by NASA itself. [25]
Oluseyi appears as a commentator and scientific authority on Science Channel television shows including How the Universe Works , Outrageous Acts of Science , Curiosity , NASA's Unexplained Files, Space's Deepest Secrets, and Strip the Cosmos ,. [26] He also appeared as a 'bakineering' (baking and engineering) judge on Netflix's Baking Impossible . [27] [28] He appeared on the National Geographic Channel show Evacuate Earth.[ citation needed ] Oluseyi appeared in the ABC special Truth and Lies: Hubris on the High Seas, which examined the Titan submersible implosion. [29]
He contributed science articles to the news media, including The Washington Post . [30] He lent his voice and scientific expertise to the award-winning science education video game ExoTrex: A Space Science Adventure Game in collaboration with Dig-It! Games. [31]
He co-authored the children's popular science book Discovery Spaceopedia: The Complete Guide to Everything Space. [32]
Oluseyi met his wife, Jessica, at Tougaloo College. They have a daughter and a son. Oluseyi has a son from an earlier relationship. [33]
The Extreme ultraviolet Imaging Telescope (EIT) is an instrument on the SOHO spacecraft used to obtain high-resolution images of the solar corona in the ultraviolet range. The EIT instrument is sensitive to light of four different wavelengths: 17.1, 19.5, 28.4, and 30.4 nm, corresponding to light produced by highly ionized iron (XI)/(X), (XII), (XV), and helium (II), respectively. EIT is built as a single telescope with a quadrant structure to the entrance mirrors: each quadrant reflects a different colour of EUV light, and the wavelength to be observed is selected by a shutter that blocks light from all but the desired quadrant of the main telescope.
Transition Region and Coronal Explorer was a NASA heliophysics and solar observatory designed to investigate the connections between fine-scale magnetic fields and the associated plasma structures on the Sun by providing high resolution images and observation of the solar photosphere, the transition region, and the solar corona. A main focus of the TRACE instrument is the fine structure of coronal loops low in the solar atmosphere. TRACE is the third spacecraft in the Small Explorer program, launched on 2 April 1998, and obtained its last science image on 21 June 2010, at 23:56 UTC.
NuSTAR is a NASA space-based X-ray telescope that uses a conical approximation to a Wolter telescope to focus high energy X-rays from astrophysical sources, especially for nuclear spectroscopy, and operates in the range of 3 to 79 keV.
Extreme ultraviolet lithography is a cutting-edge technology used in the semiconductor industry for manufacturing integrated circuits (ICs). It is a type of photolithography that uses extreme ultraviolet (EUV) light to create intricate patterns on silicon wafers.
The Multi-spectral solar telescope array, or MSSTA, was a sounding rocket payload built by Professor A.B.C. Walker, Jr. at Stanford University in the 1990s to test EUV/XUV imaging of the Sun using normal incidence EUV-reflective multilayer optics. MSSTA contained a large number of individual telescopes, all trained on the Sun and all sensitive to slightly different wavelengths of ultraviolet light. Like all sounding rockets, MSSTA flew for approximately 14 minutes per mission, about 5 minutes of which were in space—just enough time to test a new technology or yield "first results" science. MSSTA is one of the last solar observing instruments to use photographic film rather than a digital camera system such as a CCD. MSSTA used film instead of a CCD in order to achieve the highest possible spatial resolution and to avoid the electronics difficulty presented by the large number of detectors that would have been required for its many telescopes.
Arthur Bertram Cuthbert Walker Jr. was an African-American solar physicist and a pioneer of EUV/XUV optics. He developed normal incidence multilayer XUV telescopes to photograph the solar corona. Two of his sounding rocket payloads, the Stanford/MSFC Rocket Spectroheliograph Experiment and the Multi-Spectral Solar Telescope Array, recorded the first full-disk, high-resolution images of the Sun in XUV with conventional geometries of normal incidence optics. This technology is used in solar telescopes such as SOHO/EIT and TRACE, and in the fabrication of microchips via ultraviolet photolithography.
Hinode, formerly Solar-B, is a Japan Aerospace Exploration Agency Solar mission with United States and United Kingdom collaboration. It is the follow-up to the Yohkoh (Solar-A) mission and it was launched on the final flight of the M-V rocket from Uchinoura Space Center, Japan on 22 September 2006 at 21:36 UTC. Initial orbit was perigee height 280 km, apogee height 686 km, inclination 98.3 degrees. Then the satellite maneuvered to the quasi-circular Sun-synchronous orbit over the day/night terminator, which allows near-continuous observation of the Sun. On 28 October 2006, the probe's instruments captured their first images.
The Daniel K. Inouye Solar Telescope (DKIST) is a scientific facility for studies of the Sun at Haleakala Observatory on the Hawaiian island of Maui. Known as the Advanced Technology Solar Telescope (ATST) until 2013, it was named after Daniel K. Inouye, a US Senator for Hawaii. It is the world's largest solar telescope, with a 4-meter aperture. The DKIST is funded by National Science Foundation and managed by the National Solar Observatory. The total project cost is $344.13 million. It is a collaboration of numerous research institutions. Some test images were released in January 2020. The end of construction and transition into scientific observations was announced in November 2021.
The Extreme Ultraviolet Explorer was a NASA space telescope for ultraviolet astronomy. EUVE was a part of NASA's Explorer spacecraft series. Launched on 7 June 1992. With instruments for ultraviolet (UV) radiation between wavelengths of 7 and 76 nm, the EUVE was the first satellite mission especially for the short-wave ultraviolet range. The satellite compiled an all-sky survey of 801 astronomical targets before being decommissioned on 31 January 2001.

Hoover has published claims to have discovered fossilized microorganisms in a collection of select meteorites on multiple occasions.
The NIRSpec is one of the four scientific instruments flown on the James Webb Space Telescope (JWST). The JWST is the follow-on mission to the Hubble Space Telescope (HST) and is developed to receive more information about the origins of the universe by observing infrared light from the first stars and galaxies. In comparison to HST, its instruments will allow looking further back in time and will study the so-called Dark Ages during which the universe was opaque, about 150 to 800 million years after the Big Bang.
The Focusing Optics X-ray Solar Imager, or FOXSI, is a sounding rocket payload built by UC Berkeley and led by Säm Krucker to test high energy grazing-incidence focusing optics paired with solid-state pixelated detectors to observe the Sun. FOXSI is composed of seven identical Wolter-I telescope modules, as well as Silicon and Cadmium Telluride strip detectors originally developed for the HXT telescope on the Japanese Hitomi mission. The FOXSI payload flew two times, most recently in 2014 and previously in 2012. Like most sounding rockets, FOXSI flew for approximately 15 minutes per mission and observed the Sun for about 5 minutes while in space. During its first flight, FOXSI successfully imaged a solar microflare in the hard x-ray band for the first time.
Fine Guidance Sensor and Near Infrared Imager and Slitless Spectrograph (FGS-NIRISS) is an instrument on the James Webb Space Telescope (JWST) that combines a Fine Guidance Sensor and a science instrument, a near-infrared imager and a spectrograph. The FGS/NIRISS was designed by the Canadian Space Agency (CSA) and built by Honeywell as part of an international project to build a large infrared space telescope with the National Aeronautics and Space Administration (NASA) and the European Space Agency (ESA). FGS-NIRISS observes light from the wavelengths of 0.8 to 5.0 microns. The instrument has four different observing modes.

Lobster-eye optics are a biomimetic design, based on the structure of the eyes of a lobster with an ultra wide field of view, used in X-ray optics. This configuration allows X-ray light to enter from multiple angles, capturing more X-rays from a larger area than other X-ray telescopes. The idea was originally proposed for use in X-ray astronomy by Roger Angel in 1979, with a similar idea presented earlier by W. K. H. Schmidt in 1975. It was first used by NASA on a sub-orbital sounding rocket experiment in 2012. The Lobster Eye Imager for Astronomy, a Chinese technology demonstrator satellite, was launched in 2022. The Chinese Einstein Probe, launched in 2024, is the first major space telescope to use lobster-eye optics. Several other such space telescopes are currently under development or consideration.
