APLpy APLpy (the Astronomical Plotting Library in Python) is a Python module aimed at producing publication-quality plots of astronomical imaging data in FITS format. The module uses Matplotlib, a powerful and interactive plotting package. It is capable of creating output files in several graphical formats, including EPS, PDF, PS, PNG, and SVG. Python
AstroML AstroML is a Python module for machine learning and data mining built on numpy, scipy, scikit-learn, matplotlib, and astropy. It contains a growing library of statistical and machine learning routines for analyzing astronomical data in Python, loaders for several open astronomical datasets, and a large suite of examples of analyzing and visualizing astronomical datasets. Python
mpld3 The mpld3 project brings together Matplotlib, the popular Python-based graphing library, and D3js, the popular JavaScript library for creating interactive data visualizations for the web. Python
mpl Scatter Density Need to plot millions of points in Matplotlib?
mpl Scatter Density enables you to create this fast scatter density plots
Python
StingRA A Chrome extension for ArXiv. Highlight text to quickly look-up astronomical objects in Simbad, WWT and ADS.
What's Up? Updated Astroplan web application to help you plan observations R & Shiny
CosmoCalc Make various distance and other cosmological calculations based on custom set parameters. R & Shiny
AstroMap AstroMap is an [R] tool to generating sky projection maps for astronomical surveys. This tool allows a user to plot full celestial sky maps of astronomical surveys and objects, for a number of different map projections. R
SpecGen SpecGen is an [R] based package which allows users to generate simulated galaxy spectra using a number of input parameters and databases of mock galaxy spectra. R
SpecFit SpecFit is an [R] based package which allows users to display, edit and analyse 1D spectra. A spectrum is uploaded using a user-defined set of paramerters and then be displayed in various ways using multipule options. R
HyperFit Hyper Fit is an [R] package for fitting multi-dimensional data with a hyperplane available at http://github.com/asgr/hyper.fit. R
Compare Facilities Compare the wavelength and other capabilities of major astronomical facilities across the globe. R
friendlyVRI The Friendly Virtual Radio Interferometer (VRI) is designed to simulate astronomical observations using linked arrays of radio antennas in a technique called earth rotation aperture synthesis. It focuses on simulating the effect of combining different antenna layouts. Python
AladinLite Aladin Lite is a lightweight version of Aladin desktop, running in the browser and geared towards simple visualization of a sky region. It can be easily embedded on any web page and is controllable from a Javascript API.
ipyaladin An IPython Widget for Aladin Lite, enabling interactive sky visualization in IPython and Jupyter notebooks. Getting Started
arcsecond.io arcsecond.io aims at unifying the world-wide astronomy data. A place where everything is integrated; information about objects, exoplanets, observing sites, solar-system objects, telescopes, people, publications, telegrams, instruments, detectors, finding charts, and access to archived observations.
iObserve iObserve is the astronomical app you were waiting for. It is a Mac app (10.9+) that allow you to push the preparation of your observations to a much higher level. Objective-C
onekilopars.ec Far-reaching solutions for ground-based astronomers. Includes mobile apps, open-source data and APIs, and open-source libraries. In development
Pynterferometer The Pynterferometer is a graphical interface designed to demonstrated the techniques of radio interferometry used by telescopes like, ALMA, e-Merlin, the JVLA and SKA, in a manner accessible to the general public.
Astrometry.net Input an astronomical image and we'll give you back astrometric calibration meta-data, plus lists of known objects falling inside the field of view.
Nightlight Nightlight is a new desktop application that aims is to bring a modern interface to FITS files with the polish and design people expect from applications they use every day.
