What is a .FITS file?
The .FITS file extension stands for Flexible Image Transport System File. It is a type of bitmap graphic that is specifically designed to store and manage astronomical data. This format was developed under the guidance of the International Astronomical Union (IAU) and is widely used in the field of astronomy.
A .FITS file is unique because it can hold both binary data, which represents detailed image information, and ASCII text, which provides descriptive information about the image. This dual capability makes it an ideal format for handling complex astronomical images and data.
There are several software programs that can open and manage .FITS files. Some of the most commonly used programs include: 1. **NASA fv FITS Viewer** - This is a viewer developed by NASA specifically for viewing FITS files. It offers various tools for analyzing astronomical data. 2. **MicroObservatory Image** - This software is designed for educational purposes and is used to view and analyze images captured by the MicroObservatory robotic telescopes. 3. **GIMP** - A popular open-source image editor that can handle FITS files with the appropriate plugins. 4. **XnViewMP** - A versatile media viewer that supports a wide range of file formats, including FITS. 5. **MSB AVIS** - A tool used for viewing and processing astronomical images. 6. **Wolfram Research Mathematica** - A comprehensive computational software that can import and analyze FITS files as part of its data analysis capabilities. 7. **Chasys Draw IES** - An image editor that can also handle FITS files, useful for more detailed editing and processing.
FITS files are particularly valuable in astronomy because they are often used to store images and data captured from telescope observations. These files help astronomers and researchers to preserve the integrity of original observational data and facilitate detailed analysis and research in the field of astronomy.
Verification
Our goal is to help people find the most up-to-date information about file extensions for Windows, Mac, Linux, Android and iOS. We researched over 10,000 file extensions and their respective programs that open those files.
