The Saturnian system is a bountiful research location for astronomers. Within this system is
Titan, the only moon in the solar system with a fully developed atmosphere and evidence of
liquid on its surface. This moon has proven to have an abundance of methane and ethane,
organic compounds required for life, and exhibits a hydrologic system like Earth’s. There is
even a runaway greenhouse effect compacted within its thick atmosphere. Due to the tilt of
Saturn’s axis, Titan also experiences seasonal changes. For these reasons and more, Titan
demonstrates Earth-like habitats and may serve as an example of a habitable moon and
provide information into habitable zones of extra-solar systems. Thus, it begs to be studied
further. Following the end of the Cassini mission in 2017, NASA started to plan the
Dragonfly Mission. Dragonfly will launch in 2025 and will incorporate a never-before-seen
probe known as a rotorcraft. This mission will be the first craft to ever land on a moon other
than our own, and with its first few images, humans will begin to explore Titan as never
seen before. Now is the time to review surveyed data from the Cassini mission in
preparation for Dragonfly. Using the planetarium dome, I will explore the journey of Cassini
through the rings of Saturn, the relationship between Titan and Saturn, and finally delve
into the findings of the Cassini-Huygens mission that mapped out Titan for future
investigation by the Dragonfly project.
Study of parabens in various cosmetic products using UV/VIS Spectrometer

Parabens are commonly used in cosmetics as preservatives to prevent the growth of harmful
bacteria and mold. However, public safety concerns have arisen due to research indicating
their effects on hormones, reproductive organs, and possible increased cancer risk, especially
in women. To date, the FDA has not established specific regulations for permissible paraben
concentrations. In our research, we employ a UV /VIS spectrometer to measure the levels of
various parabens, such as methylparaben, ethylparaben, and propylparaben, which are
frequently found individually or combined in everyday items like shampoos, conditioners,
lotions, and skincare products. Our research aims to offer insights into potential daily
paraben exposure levels, ultimately enhancing public awareness of consumer safety.
