Scientists' best estimate is that the universe is about 13.8 billion years old..
Researchers in the Astronomy Department are involved with specific projects involving large empirical and simulation data sets: spacecraft imaging data from solar system missions, spacecraft survey data for exoplanets, sky surveys at radio, infrared, and optical wavelengths, data sets from gravitational wave detectors, .
The astronomer spends the entire night pointing the telescope at distant objects -- planets, stars, nebulae, or galaxies -- and collecting the faint trickle of light from each object.
A computer stores the data for later analysis..
And rather than looking through an eyepiece, like astronomers of yore, researchers today collect an enormous array of observations across the electromagnetic spectrum, from X-rays to radio waves, using sophisticated digital detectors.Mar 27, 2023.
The first documented records of systematic astronomical observations date back to the Assyro-Babylonians around 1000 BCE.
From this cradle of civilisation in Mesopotamia – in the southern part of present-day Iraq – astronomers had built up knowledge of the celestial bodies and recorded their periodic motions..
To understand what they are seeing, astronomers must examine vast amounts of data gathered by telescopes in space and on the ground.
Astronomers are aided in this task by data centers, which process, analyze, and archive the information.

So the furthest out we can see is about 46.5 billion light years away, which is crazy, but it also means you can look back into the past and try to figure out how the universe formed, which again, is what cosmologists do..
Astronomers study celestial phenomena by making observations across the electromagnetic spectrum.
Space astrophysics data collected from NASA's flight missions include observations in gamma-ray, X-ray, extreme ultraviolet, ultraviolet, optical, infrared, and microwave wavelengths..

Astronomical data mainly include images, spectra, time-series data, and simulation data.May 22, 2015.
Astronomical data are primarily comprised of images, spectra, time series, and simulation data.
The majority of data are stored in catalogs or databases..
Astrostatistics puts numbers on what we learn from these observations, and equally importantly how good both the measurements and our interpretations are.
Along with machine learning, astrostatistics allows astronomers to find patterns that might otherwise be missed..

and Big Data (including data acquisition, storage and analysis).
Present astronomical databases and archives contain billions of objects observed in various wavelengths, both Galactic and extragalactic, and the vast amount of data on them allows new studies and discoveries.
Astronomers deal with big numbers..
Answer: Data science contributes to the understanding of the cosmos by identifying patterns, creating predictions, and expanding our understanding of the universe.
Modern space missions and sophisticated telescopes have transformed data collection, resulting in a vast influx of astronomical data..
