When astrophysicist Dr. Héctor Arce returned home to Puerto Rico in October of 2015, it was to bring a handful of Yale astronomy students to Arecibo Observatory, at that time, the largest single dish radio telescope in the world. For Héctor, a professor of astrophysics at Yale University, passion for the stars started at home. When Héctor was young, his grandfather used to build his own telescopes. “I still have them,” Héctor says. Staring through the lenses of those telescopes with his grandfather opened a universe of possibility for young Héctor.

It’s that time of the year again: the smell of charcoal, children gleefully splashing water at the beach, frozen lemonades, and endless warm nights staring at the mystifying skies… Did you know that some of the stars you see are bigger and brighter than our sun? That some of them don't exist anymore since their light travels millions of years to reach us?  Astronomy, one of the oldest sciences, helps us understand objects and matter outside the Earth's atmosphere—stars, planets, comets, galaxies and black holes—and their physical and chemical properties. 

Dr. Marcel Agüeros has made astronomy his life's work and passion. 

His Astronomical Journey

The study of the planets, the stars, and the universe, in which we live, is the passion of many scientists.. Since the times of the British astronomer Edmund Halley and the British physicist Isaac Newton, the study field of Astronomy has been essential to understand what distinguishes celestial objects (position, distribution, movement, composition and energy).
