Nidia Irene Morrell (born 3 July 1953) is an Argentine astronomer who is a permanent staff member at the Las Campanas Observatory in La Serena, Chile.

[4] In late 2002, Morrell joined the scientific team at Las Campanas Observatory and, later, the Carnegie Supernova Project (as a part-time researcher), while continuing to collaborate on massive star studies.

[9] In 2009, she appeared in the documentary video El silencio de las Campanas made by Ricardo Benítez, which follows the daily activity of astronomers at a high-level observatory.

[15] While nowhere in the world are resources abundant, I would say that science is going through a wonderful moment, where international collaboration is clearer and more fluid than ever (especially because of the ease of sharing information and knowledge through the Internet).

Maybe that is the greatest achievement, the fulfillment of a vocation, although other things in life have not gone well, being able to dedicate oneself to something that one likes so much is a valuable achievement, a privilege if you will.For her passion for astronomy, her dedication to mentoring students, and the enormous amount of observational data she has gathered, the international conference Massive Stars and Supernovae was held in celebration of her 65th birthday.

[20] Both for Dr. Morrell's scientific achievements and for her charisma, in the course of this meeting it was announced that the International Astronomical Union named an asteroid (Minor Planet 25906) in her honor.
