Ewine van Dishoeck, an astronomer and astrochemist, is a pioneer in her field, pushing the boundaries of what we know about the universe and the origins of life. Her work, which takes place in the vast, cold expanse of space, is a testament to the power of human curiosity and the endless possibilities of scientific exploration. In an interview with EL PAÍS, van Dishoeck shared her insights on the chemistry of space, the formation of stars and planets, and the search for life beyond Earth.
One of the most fascinating aspects of van Dishoeck's work is her focus on interstellar dust. She describes herself as a fan of this cosmic material, which plays a crucial role in the formation of molecules in space. Interstellar dust, she explains, acts as a kind of meeting place for atoms and molecules, facilitating the creation of complex chemical compounds. This is particularly intriguing, as it suggests that the building blocks of life may have formed in the vast, empty void of space.
Van Dishoeck's research has also shed light on the chemical diversity found in planet-forming zones. She notes that while water is present in sufficient amounts to make a new solar system, the diversity of organic molecules varies greatly. Some regions are rich in water and carbon dioxide, while others are more abundant in hydrocarbons. This diversity raises questions about the conditions necessary for life to emerge and thrive.
One of the most intriguing aspects of van Dishoeck's work is her skepticism about the ease of finding the 'signature of life' in other solar systems. While she acknowledges the potential for the James Webb telescope to detect traces of life, she remains cautious. She points out that the detection of dimethyl sulfide in the universe could be abiotic, and emphasizes the need for more advanced technology, such as the Extremely Large Telescope, to make definitive conclusions.
Despite her skepticism, van Dishoeck is optimistic about the future of astrochemistry. She believes that the James Webb telescope has already provided valuable insights into the chemistry of planet-forming zones, and that future missions will build upon this knowledge. She sees the search for life beyond Earth as a journey of discovery, one that will require patience and a willingness to explore the unknown.
In addition to her scientific contributions, van Dishoeck has also been a strong advocate for diversity and inclusion in science. She reflects on her own experiences as a woman in a male-dominated field, and notes that the astronomy department she worked in was one of the most flat in terms of hierarchy. She believes that science diplomacy can play a crucial role in calming international tensions, and sees astronomy as a powerful tool for building bridges between people and cultures.
Overall, van Dishoeck's work is a testament to the power of human curiosity and the endless possibilities of scientific exploration. Her insights into the chemistry of space, the formation of stars and planets, and the search for life beyond Earth are not only fascinating, but also raise important questions about the origins and future of our universe.
