At Vatican observatory, Goa priest decoding cosmic past

PANAJI: Physicist, astronomer, scientist, Indiana Jones. Not rather the words to picture a priest, fto unsocial a 46-year-old Jesuit from Mapusa. But that is precisely what Fr Richard D’Souza is.At the Vatican Observatory successful Castel Gandolfo, an past castle that erstwhile hosted pontiffs, D’Souza is piecing unneurotic the convulsive past of galactic cannibalism — the depletion of smaller galaxies by larger ones. “My enactment is fundamentally to recognize the histories of galaxies. I effort to beryllium a galactic archaeologist, truthful I enactment connected this Indiana Jones headdress and I effort to spot however galaxies turn to the monolithic size that they are,” helium said.His breakthrough came successful 2018, published successful Nature Astronomy, erstwhile helium and Eric Bell projected that the Andromeda galaxy’s astir important merger — a convulsive collision that reshaped the Milky Way’s nearest galactic neighbour — occurred astir 2 cardinal years ago.D’Souza’s ain trajectory was little violent. Born successful Pune successful 1978, raised partially successful Kuwait and partially successful Goa, helium entered the Society of Jesus, the ceremonial sanction of the Jesuits, astatine 18.

A Catholic bid known for its intelligence pursuits, the nine recognised successful him thing worthy nurturing.“I utilized to spell for camping trips portion studying astatine St Britto’s, successful the countryside, acold distant from the metropolis lights wherever you could spot the nighttime sky. This was possibly my archetypal involvement successful the heavens, and this was confirmed a batch during my novitiate successful Desur, Belagavi, which was a distant spot wherever I could spot the nighttime sky,” said D’Souza.For his Jesuit formators, D’Souza’s way was neither consecutive nor predictable. After completing his physics grade astatine St Xavier’s College, Mumbai, helium pursued a master’s grade successful Heidelberg, moving astatine the Max Planck Institute for Astronomy. Then came doctrine successful Pune, arsenic his Jesuit enactment demanded, followed by theology. Then, a gravitational pull-back to physics done his doctoral enactment astatine the Max Planck Institute for Astrophysics successful Munich.“I earnestly started reasoning of astronomy arsenic a vocation erstwhile I started my master’s successful physics astatine Heidelberg, wherever I did immoderate tiny probe task connected astronomy, and it was this that truly attracted me. I fell successful emotion with the subject,” helium said.Between doctrine and theology, helium concisely veered towards societal enactment successful 2007 erstwhile helium helped commencement St Paul’s Community College successful Belagavi for schoolhouse dropouts. This oscillation betwixt the cosmic and the communal, betwixt the spiritual and the celestial, should beryllium debilitating.

Not for him.“Our enactment astatine the observatory is fundamentally doing technological probe with 80-90% of our clip going successful collecting and analysing data, and going for conferences. The remaining 10% of the time, we punctual the Church that religion and subject request to spell together,” said D’Souza.Since 2022, D’Souza has served arsenic superior of the Jesuit assemblage attached to the Vatican Observatory. He is present manager of the observatory itself, 1 of the oldest astronomical institutes successful the satellite that dates backmost to 1774.Given that helium straddles the 2 heavenly realms of theology and astronomy, helium is often asked astir extraterrestrial life. “I was waiting for this question and my effect is, convey God I americium not an adept connected that,” helium precocious said astatine an lawsuit successful Porvorim, blending humour with pragmatism.
