A Colombian engineer and astrophotographer, Mónica Mesa, became the first woman from her country to have her image selected by NASA’s Astronomy Picture of the Day (APOD), showcasing the Large Magellanic Cloud. The photograph, captured during an expedition in Chile, highlights the galaxy’s star-forming regions and irregular structure, chosen for its scientific and visual merit.
Mónica Mesa, an engineer and astrophotographer based in Colombia, made history on August 9, 2026, when her photograph of the Large Magellanic Cloud (LMC) was selected as NASA’s Astronomy Picture of the Day (APOD). The image, taken during an expedition in Chile, captures the galaxy’s irregular structure, star-forming regions, and dense stellar fields. The LMC, located approximately 160.000 light-years from Earth, is a satellite galaxy of the Milky Way and a key object for studying stellar evolution and galactic interactions.
The Photograph and Its Significance
The selected image, which Mesa described as It’s impressive to see it with the naked eye, so beautiful, so impactful. emphasizes the LMC’s role as a laboratorio natural
for observing star formation. The galaxy, part of the Local Group, is notable for its active star-forming regions, including the Tarantula Nebula, one of the most intense sites of stellar birth in the Local Group.
Mesa’s achievement marks a milestone for Colombian astronomy. She is the first woman from her country to appear on APOD and the second Latin American overall, following Colombian engineer Mario Vargas, who was selected weeks earlier. The APOD platform, active since 1995, selects one image daily from global submissions, prioritizing scientific value, visual appeal, and technical excellence.
Challenges of Astrofotography in Colombia
Mesa described the challenges of astrophotography in Colombia, stating Hacer fotografías en Colombia es de aguerridos.
Her photograph of the LMC was taken under conditions of exceptional darkness and atmospheric transparency, as noted by caracol.com.co. The image’s visibility from southern Colombia, particularly during months like January, February, and December, underscores the interplay between geography and celestial observation. The LMC’s proximity to the Milky Way also allows for detailed studies of its structure, which NASA’s Cecilia Chirenti described as Especially valuable for studying processes related to the evolution and birth of stars.
Technical and Scientific Merits
Long-exposure techniques, combined with specialized software, enabled her to capture the LMC’s faint details, including its irregular shape and star-forming nebulae.
In 1987, the supernova SN 1987A occurred within the galaxy, making it the closest observed supernova since the invention of the telescope. This event provided critical data for understanding stellar explosions and their role in cosmic evolution.
What’s Next for Colombian Astrofotography?
As one source noted, her work bridges the scientific value of the object it portrays and the technical work necessary to turn a sky observation into an image capable of being internationally recognized.
