by Imagine what data science could do for highly complex subjects like astrophysics if it could help corporations in typical industries like technology, manufacturing, and retail better their operations. There are several wonderful celestial objects out there that are simply waiting to be seen and found in boundless space. Now that they have the appropriate technological capabilities and blazing-fast data science tools (many powered by AI and machine learning), astronomers can finally perfect their ability to interpret extremely complicated celestial occurrences locally and globally.
Data science is valuable in all industries including astronomy and you can find a variety of applications. Know more about data science applications and tools via the best data science courses in India.
Data Science in Astronomy
Data-driven Astrology (DDA), as the name suggests, is the method for developing astronomical understanding based on historical sets of data that might or might not be pertinent to the subject at hand. Astrophysicists were tasked with classifying 900,000 images 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 or not.
A great example is the Galaxy Zoo project from 2007, which involved classifying galaxies into galaxies. The enormous quantity of information involved made human analysis all but impossible. In order to finish it, one individual must put in three to five years of nonstop labor.
To measure massive empirical and simulated data sets, the solution rests in developing new data science models. These data sets include information from solar missions, planetary surveys, sky surveys at different wavelengths, gravitational wave detectors, and extensive astronomical simulations. Together, they assist astronomers in achieving their significant scientific goals.
Knowing Our Sun Better With Data Science in Astronomy
Among all potential energy sources for our planet, the sun is arguably the largest. In addition to being used for solar energy production, the sun is a natural example of fusion energy, making it a crucial part of efforts to promote sustainability and clean energy. The data that scientists are able to gather, however, is the only limit to our comprehension. For instance, it is relatively simple to monitor the temperature of the sun and the vertical motion of solar plasma, whereas the horizontal motion, which is considerably more difficult to measure but is the key to many of the sun’s secrets, is much more difficult.
Scientists from the US and Japan create a neural network model to assess data from several simulations of plasma turbulence to resolve the issue. Using only vertical motion and temperature as references after training the neural network, it was possible to predict horizontal motion. Further to having vast implications for solar astronomy, this method also has applications in plasma physics, fluid dynamics, and fusion research projects. High-resolution sun observations with the brand-new SUNRISE-3 balloon telescope are another project that will use this data type.

Data science using crowdsourcing for astronomy
The method of enlisting thousands of “citizen scientists” to join their efforts to map the heavens and analyze data at scale is known as crowdsourcing. It is another frequent application of data science in astronomy. Thanks to the Exoplanet Explorers project, which utilized information from the NASA Kepler satellite observatory (outside our own solar system), five exoplanets have been found. It is the first system with many planets that was entirely found by data analysis performed by the public. Initially, the research suggested a four-planet system; however, additional data analysis indicated the presence of a fifth planet. The crowdsourcing effort involved over 14,000 people, and as additional data comes in over time, they continue to study and analyze it.
Exploration of Mars using Data Science in Astronomy
Long-running robotic missions will soon bring samples from the surface of Mars to researchers finding signs of life. Mass spectrometry analysis will be the main technique used by the missions to look through a sampling of Martian sands for signs of a prior life. NASA needs new methods to quickly examine the samples as it has a massive collection of information to analyze. NASA has created the Mars Spectrometry: Identify Evidence for Past Life challenge (with a prize of $30,000 for the most creative analysis technique) to address the problem. HeroX, a global crowdsourcing firm, and DrivenData, a provider of data science, have linked up with NASA.
Scientists want to simplify the task of chemical analysis and draw significant results more quickly by utilizing machine learning techniques, which involve processing enormous data sets into new analytical models. To enable analysis and assist in interpreting data gathered more by missions in in-situ samples and lab devices, individual competitors will need to construct machine-learning models. Also, the outcomes are anticipated to make future Mars missions more rapid and effective.
Final Thoughts
When applied to complex subjects like astronomy, data science can do astounding things. There is no denying that our data-driven world is becoming increasingly exciting, whether it be through the development of new machine learning models that analyze data at breakneck speed, the collection of data from tens of thousands of amateur astronomers, or the application of cutting-edge data science techniques by institutions like NASA.
