The Emerging Role of Data Science in Astronomy
Imagine what data science can do for highly complex fields like astronomy if it can help businesses in traditional industries like technology, manufacturing, and retail improve their operations. There are countless amazing celestial objects out there waiting to be seen and discovered in infinite space. Now that they have the right technological tools and blazing-fast data science tools (many powered by AI and machine learning), astronomers can finally perfect their ability to make sense of astronomical events, both close to home and far away, that is extremely complex.
Advances in Data Science in Astronomy
Data-driven Astronomy (DDA) does what it says on the tin: it creates astronomical knowledge based on archived data sets, which may or may not be directly related to the research at hand. Astrophysicists were tasked with classifying 900,000 images obtained from the Sloan Digital Sky Survey over the course of seven years to determine whether galaxies were elliptical or spiral and whether they were spinning. This task was accomplished as part of the Galaxy Zoo project in 2007, which is a great example.
Human analysis was nearly impossible due to the enormous amount of data involved. One person would need to work nonstop for three to five years to finish it. New data science models must be developed to measure large empirical and simulation data sets. Data from solar missions, exoplanet surveys, sky surveys at various wavelengths, gravitational wave detectors, and large-scale astronomical simulations are all included in these data sets. They assist astronomers in achieving their significant research goals by working together.
Using Data Science in Astronomy to Better Understand Our Sun
The sun is arguably the planet's greatest potential energy source. Not only for solar power but also as a natural example of fusion energy, solar energy is a crucial part of efforts to promote sustainability and clean energy. However, the information scientists can gather limits how much we can understand. For instance, the horizontal motion of solar plasma is much harder to observe than the sun's temperature, and it holds the key to many of the sun's mysteries.
To address the issue, scientists from the US and Japan construct a neural network model to analyze data from numerous simulations of plasma turbulence. After the neural network was trained, using only temperature and vertical motion as references, it was possible to infer horizontal motion. This method has broad applications for solar astronomy as well as for the study of fusion, fluid dynamics, and plasma physics. The new SUNRISE-3 balloon telescope will be used for high-resolution solar observations as part of additional projects utilizing this type of data.

Data Science for Astronomy through Crowdsourcing
Crowdsourcing, or the method of utilizing thousands of "citizen scientists" to combine their efforts to map the skies and analyze data at scale, is another frequent application of data science in astronomy. At least five exoplanets were found by the Exoplanet Explorers project using information from the NASA Kepler space telescope (outside our own solar system). The entire discovery of this multi-planet system came from crowdsourced data analysis efforts. Research initially indicated a four-planet system, but later data analysis revealed the presence of a fifth planet. The crowdsourcing project involved over 14,000 volunteers, and more are still viewing and analyzing data as it comes in over time.
Astronomical Data Science: Investigating Mars
Researchers have been looking for signs of life on Mars for many years, and soon, fresh robotic missions will bring back samples from the planet's surface. The missions will examine the Mars sand samples using mass spectrometry to look for evidence of earlier life. NASA needs new techniques to analyze the samples quickly because the amount of data that needs to be analyzed will be enormous. The Mars Spectrometry: Detect Evidence for Past Life challenge (with a prize of $30,000 for the most creative method of analysis) was developed by NASA in collaboration with global crowdsourcing company HeroX and data science vendor DrivenData to address the challenge.
Scientists want to automate the process of chemical analysis and draw significant conclusions more quickly by using machine learning techniques, which crunch enormous data sets into new analytical models. In order to support analysis and aid in the interpretation of data gathered by the missions in in-situ samples and lab instruments, individual competitors will need to develop machine learning models. Additionally, it is anticipated that the outcomes will improve the speed and effectiveness of future Mars missions.
Conclusion
The results are astounding when data science is used in complex fields like astronomy. There is no doubt that our data-driven world is becoming increasingly exciting, whether it be through the development of new machine learning models to analyze data at breakneck speed, the collection of data from tens of thousands of amateur astronomers, or the use of cutting-edge data science methods by organizations like NASA.
