Listed here are software packages useful for conducting scientific research in astronomy, and for seeing, exploring, and learning about the data used in astronomy. Package Name Pro
Its first version was developed by German astrophysicist, Volker Springel and was published in 2000. [16] It was followed by two more official public versions, with GADGET-2 [17] [18] released in 2005 and GADGET-4 [19] [20] released in 2020, which is the most recent public version of the software suite currently. GADGET is capable to address a ...
Ground track example from Heavens-Above.An observer in Sicily can see the International Space Station when it enters the circle at 9:26 p.m. The observer would see a bright object appear in the northwest, which would move across the sky to a point almost overhead, where it disappears from view, in the space of three minutes.
An N-body simulation of the cosmological formation of a cluster of galaxies in an expanding universe. In physics and astronomy, an N-body simulation is a simulation of a dynamical system of particles, usually under the influence of physical forces, such as gravity (see n-body problem for other applications).
Software is available to use the JPL ephemerides for the production of apparent ephemerides for any location and time; these are widely used by professional and amateur astronomers for reducing planetary observations and producing very precise observing guides. [16] Recent ephemerides can be used with the planetarium software Stellarium.

Gravity is a software program designed by Steve Safarik [1] to simulate the motions of planetary bodies in space. Users can create solar systems of up to 16 bodies. Mass, density, initial position, and initial velocity can be varied by user input. The bodies are then plotted as they move according to the Newtonian law of gravitation.
The strength of seeing is often characterized by the angular diameter of the long-exposure image of a star (seeing disk) or by the Fried parameter r 0. The diameter of the seeing disk is the full width at half maximum of its optical intensity. An exposure time of several tens of milliseconds can be considered long in this context. The Fried ...
