CDAWeb is a service of NASA's Space Physics Data Facility that holds selected public non-solar heliophysics data from current and past missions and projects. It supports creating data subsets by date and variables, uniformly time binned data, plots in PDF, PS and PNG formats, and movies of image sequences. All SPDF services are unavailable during monthly system maintenance.
Celestia is a free space simulator that provides real-time 3D visualization of space. It displays objects and orbits based on scientific data and runs on Windows, Linux, macOS, iOS and Android. Users can travel through the solar system, to over 100,000 stars, or beyond the galaxy. Its catalogues are expandable with add-ons, and users can create their own objects and planetary systems.
darktable is an open source photography workflow application and raw developer. It manages digital negatives in a database, provides a zoomable lighttable view, and develops raw images non-destructively. It runs on Linux, Mac OS X, BSD, Windows and Solaris, and is released under GPL 3.0.
Dynamic Wallpaper Club is a website that offers a gallery of free dynamic wallpapers for macOS and a creator tool for making them. Wallpapers can change over the course of the day in time mode or follow the sun's position in solar mode. The site also lets users share wallpapers with the community or add others' wallpapers to a collection.
Equinox is a free and open-source application for creating dynamic wallpapers for macOS. It offers three wallpaper types: solar, based on the sun's position; time, based on chosen times; and appearance, which uses one image for light mode and one for dark mode. Wallpapers can be set right after creation.
GnuCash is personal and small-business financial-accounting software, freely licensed under the GNU GPL. It is available for GNU/Linux, BSD, Solaris, Mac OS X and Microsoft Windows. It allows tracking of bank accounts, stocks, income and expenses, and is based on professional accounting principles for balanced books and accurate reports. Feature highlights include double-entry accounting, stock and mutual fund accounts, reports and graphs, and QIF/OFX/HBCI import.
The GOES 1–15 Space Environment Monitor covers space-weather instruments carried on NOAA's GOES 1–15 satellites, used since 1975 to monitor weather and space weather. The instruments measured particles, the magnetic field and solar irradiance and imaged the Sun. The page provides documentation, data and instrument details, noting that data anomalies should be checked against other sources.
htop is a cross-platform interactive process viewer. It is a text-mode application for console or X terminals and requires ncurses. Current releases support Linux, FreeBSD, NetBSD, OpenBSD, DragonFly BSD, MacOS and Solaris.
The NASA/IPAC InfraRed Science Archive (IRSA) curates and provides access to science products from NASA's infrared and submillimeter missions. It offers search functionality for source catalogs from missions including WISE, 2MASS, Spitzer, Planck, Herschel, Gaia, and others, along with contributed datasets, documentation, and user support resources including a guide for solar system observers.
The Open Energy Data Initiative (OEDI) is a searchable online software discovery platform and knowledge base developed by NLR and powered by OpenEI. It provides open access to energy data and information to support research, collaboration and transparency, with features including curated data lakes, solar systems integration data and analytics tools, and a siting lab.
OMG SPACE is a series of visuals created as a graphic design thesis project to illustrate the true scale of the solar system. All planets, including the sun and dwarf planets, are shown to scale, as are their distances from the sun, at a ratio of 1:647. Created in 2011 by Margot Trudell, the site's data is only current to early 2011, with minor design and development updates in 2015.
Open Power System Data is a free-of-charge data platform for electricity system researchers and power system modelling. It collects, checks, processes, documents and publishes publicly available power system data that is inconvenient to use, covering installed generation capacity, individual power plants and time series such as consumption, spot prices and wind and solar generation. Processing scripts are open source on GitHub and data is published primarily as CSV files with JSON metadata.
OpenEI is an open energy information platform that provides access to crowdsourced energy data, information, and applications from industry and government agencies. It covers hundreds of energy-related topics including geothermal, solar, wind, hydrogen, utilities, buildings, and smart grid. Its resources support education, data exploration, and industry decision-making, and include initiatives such as the Open Energy Data Initiative, Utility Rate Database, and specialized data repositories and toolkits.
Orbity.io is an online multiplayer 2D space orbiting browser game. It offers a Classic universe with scoreboards, a main Campaign with missions and ship upgrades, and an experimental Solar System universe. A full mouse-and-keyboard PC experience is recommended.
The CDPP is the French national data centre for natural plasmas of the solar system. Created in 1998 by CNES and INSU, it preserves data primarily from instruments built using French resources and makes them accessible to the international community. It also offers online services including data analysis, 3D visualisation, a propagation tool and a space weather tool.
SIMBAD is an astronomical database operated at CDS, Strasbourg, providing basic data, cross-identifications, bibliography and measurements for astronomical objects outside the solar system. It can be queried by object name, coordinates and various criteria. The database is updated every working day, and use is free without registration under the ODbL licence. The CDS team notes that SIMBAD is not a catalogue.
smartmontools is a package of two utility programs, smartctl and smartd, for controlling and monitoring storage systems using SMART. It supports ATA/SATA, SCSI/SAS and NVMe disks and SCSI/SAS tape devices, and is documented as running on Linux, FreeBSD, NetBSD, OpenBSD, macOS, Solaris, Windows, Cygwin, OS/2, eComStation and QNX.
SolarHam is a space weather and aurora website founded in 2006. It provides real time data and new updates, including solar indices, imagery, flare probabilities and geomagnetic forecasts. Its help center explains space weather terms such as coronal holes, coronal mass ejections and geomagnetic storms, and notes that the section is being built.
Space Time is a browser-based 3D universe explorer built from astronomical catalogs, telescope surveys and computed motion. It covers the solar system, stars, deep-sky objects and the observed cosmic web in one continuous view, with no account required. It is free and requires no download.
SunCalc is an online application for showing the movement of the sun and sunlight phases for a selected day and place. It displays sunrise, sunset, shadow length, solar eclipse, sun position and elevation on an interactive map, and includes reverse calculation and photovoltaic data.
Syncthing is a continuous file synchronization program that synchronizes files between two or more computers in real time. Communication is secured using TLS with perfect forward secrecy, and each device is identified by a cryptographic certificate. The protocol is documented and the source code is available on GitHub. It runs on macOS, Windows, Linux, FreeBSD, Solaris, OpenBSD and other systems, and is configured through a browser interface.
TheSkyLive provides information about celestial objects and tools for exploring and observing the night sky. It includes star maps, a 3D Solar System viewer, visibility listings for planets, comets and asteroids, and guides to eclipses and the Moon. Users can set an observing location, and without one the site defaults to Greenwich.
tmux is a terminal multiplexer that lets multiple terminals be created, accessed and controlled from a single screen. It can be detached from a screen, continue running in the background, and be reattached later. The source repository runs on OpenBSD, FreeBSD, NetBSD, Linux, macOS and Solaris and depends on libevent 2.x and ncurses.
ViewSpace is a free, web-based collection of astronomy and Earth science videos and interactives. It offers image tours, image sliders, and a video library that let users explore the planet, solar system, galaxy, and universe. The project is developed by the Space Telescope Science Institute with NASA support and has been exhibited in museums, planetariums, and science centers since 2000.
