Big Data in Astronomy by https://padlet.com/brionchoi/h2l7qhps6xv en-us 2017-06-01 23:02:56 UTC 2026-01-27 03:44:38 UTC hello@padlet.com Info about Astronomy brionchoi https://padlet.com/brionchoi/h2l7qhps6xv/wish/174895970 There are many types of areas in which astronomy branches off into.
Astronomy is the study of the physics, chemistry, and evolution of objects and phenomena outside of the Earth's atmosphere.
Astrophysics is the branch of astronomy that studies the physics of the universe especially in the nature of celestial objects than the positions or motions in space.
Astrostatistics is an field of astronomy/astrophysics and statistics that applies statistics to the study and analysis of astronomical data.
Astroinformatics is an field of astronomy/astrophysics and informatics that uses information/communications technologies to solve the big data problems faced in astronomy.

DPOSS (The Palomar Digital Sky Survey) | 3 TB
2MASS (The Two Micron All-Sky Survey) | 10 TB
GBT (Green Bank Telescope) | 20 PB
GALEX (The Galaxy Evolution Explorer) | 30 TB
SDSS (The Sloan Digital Sky Survey) | 40 TB
SkyMapper Southern Sky Survey | 500 TB
PanSTARRS (The Panoramic Survey Telescope and Rapid Response System) | ~ 40 PB expected
LSST (The Large Synoptic Survey Telescope) | ~ 200 PB expected
SKA (The Square Kilometer Array) | ~ 4.6 EB expected]]> 2017-06-01 23:06:29 UTC https://padlet.com/brionchoi/h2l7qhps6xv/wish/174896188 How Big Data is used in Astronomy brionchoi https://padlet.com/brionchoi/h2l7qhps6xv/wish/174896420 A large amount of data is collected indiscriminately by satellites. It is then the job of data analysts to find patterns and significant data that is relevant. Before this task of collecting large amount of data and analysing them was impossible due to how large the data set was. However, with the recent technological advances, data is now able to be discerned with the aid of computers.]]> 2017-06-01 23:09:02 UTC https://padlet.com/brionchoi/h2l7qhps6xv/wish/174896420 brionchoi https://padlet.com/brionchoi/h2l7qhps6xv/wish/174896881 2017-06-01 23:13:45 UTC https://padlet.com/brionchoi/h2l7qhps6xv/wish/174896881
