The Roman Space Telescope took off this Sunday from Florida aboard a Falcon Heavy rocket, marking the start of a mission aimed at exploring the mysteries of the cosmos and expanding astronomical knowledge.

The device, over 12 meters tall, was developed over more than a decade and required an investment exceeding USD 4 billion.
The Roman was designed to capture images of vast areas of space and provide data to study fundamental enigmas of modern physics. It has a field of view more than 100 times greater than that of the Hubble Space Telescope, launched on April 24, 1990.
From its position 1.5 million kilometers from Earth, it will be able to observe regions of space unreachable by other observatories and offer a record of exoplanets and supernovae. It is expected to observe thousands of exoplanets and tens of thousands of supernovae.
NASA named the telescope in honor of Nancy Grace Roman, a pioneer of American astronomy and known as the “mother of Hubble.” The mission aims to expand the atlas of the universe and deepen the study of dark matter and dark energy.
Dave Content, the telescope’s technical lead, stated that “it will be the largest catalog of astronomical objects ever created and will help us understand how common solar systems like ours are.”
The device is equipped to detect light from celestial objects emitted billions of years ago, allowing scientists to observe the distant past of the universe and analyze various phenomena.
Dark matter and dark energy, which make up 95% of the universe, will be at the center of the research. According to the background provided, the former is believed to act as a “gravitational glue” and the latter as a force driving the expansion of the cosmos.
The project’s lead researcher, Julie McEnery, stated that “recent observations suggest that our standard model of the universe is incorrect.” According to what was indicated, the telescope will help determine whether current models are accurate or if a revision in the conception of cosmic expansion is required.
Another challenge will be processing the volume of information generated by the observatory. “The telescope will generate about 1.3 terabytes of data per day, which means that basically no one can download the data onto their laptop,” Content said.
Access to the data will be open both to the scientific community and the general public. Additionally, the Roman will operate in conjunction with other observatories such as Webb and the Euclid probe.
Content maintained that the most significant discoveries could be unexpected: “I expect a lot, and in fact take for granted, that the most exciting scientific discoveries of the Roman will be a surprise, something we cannot foresee and that will lay the foundation for the next, deeper set of questions that future missions will have to address.”
