Which MIME types are related to file extension ".fit"?
The .fit file extension is associated with 3 MIME types:
application/fits, image/fits, application/octet-stream.
A MIME type is a string that tells browsers and other tools how to handle a particular kind of file.
About .fit Files
FIT files are a type of file that store scientific image data in the Flexible Image Transport System format. They are mainly used in astronomical research and for specific game data applications.
- Astronomy Data: FIT files handle telescope images, spectra, and multi-dimensional datasets. They retain extensive metadata and are opened by programs such as SAOImage DS9 and Aladin. They use MIME types like application/fits and image/fits.
- Gaming Data: Some FIT files contain binary data for the Mechwarrior game. These files, identified by the MIME type application/octet-stream, require game-specific software to be used properly.
Relationship between file extension and MIME type
A file extension is a suffix at the end of a filename that indicates what type of file it is. File extensions help both users and operating systems identify what application should be used to open the file.
File extensions are typically separated from the filename by a period (dot) and consist of 2-4 characters, though they can be longer. For example, in the filename "document.pdf", ".pdf" is the file extension.
File extensions are closely related to MIME types, as they both serve to identify the format of a file. However, while MIME types are used primarily by web browsers and servers, file extensions are used by operating systems and applications.

FAQs
What is a .fit file?
A .fit file is primarily a Flexible Image Transport System file used by astronomers to store images and metadata. Occasionally, it may also be a binary data file used by the Mechwarrior video game series.
How do I open a .fit file containing astronomical data?
You can open these files using specialized scientific software such as SAOImage DS9, Aladin, or NASA's FV. The free image editor GIMP also supports opening FITS files natively.
Can I view .fit files in Adobe Photoshop?
Photoshop does not support the format out of the box. To open a .fit file in Photoshop, you must install a plugin like the ESA/ESO/NASA FITS Liberator.
How do I convert a .fit file to JPG or PNG?
You can use GIMP to open the file and export it to a standard image format. Alternatively, online converters or the FITS Liberator tool can convert the high-dynamic-range scientific data into a viewable image like a JPEG.
Why won't my .fit file open in image viewers?
If standard or scientific viewers fail, you likely have a Mechwarrior game file rather than an image. These files are often binary blobs classified as application/octet-stream and are not meant to be opened manually.
What is the correct MIME type for serving .fit files?
For astronomical data, the standard MIME types are application/fits or image/fits. Ensuring the correct type is configured on your server helps browsers handle the file appropriately; see mime-type.com for more details.
Is a .fit file the same as a .fits file?
Yes, .fit is simply a three-letter abbreviation for .fits. Both extensions refer to the same Flexible Image Transport System format and are completely interchangeable.
General FAQ
What is a MIME type?
A MIME (Multipurpose Internet Mail Extensions) type is a standard that indicates the nature and format of a document, file, or assortment of bytes. MIME types are defined and standardized in IETF's RFC 6838.
MIME types are important because they help browsers and servers understand how to process a file. When a browser receives a file from a server, it uses the MIME type to determine how to display or handle the content, whether it's an image to display, a PDF to open in a viewer, or a video to play.
MIME types consist of a type and a subtype, separated by a slash (e.g., text/html, image/jpeg, application/pdf). Some MIME types also include optional parameters.
How do I find the MIME type for a file?
You can check the file extension or use a file identification tool such as file --mime-type on the command line. Many programming languages also provide libraries to detect MIME types.
Why can one extension have multiple MIME types?
Different programs and historical usage may assign various MIME identifiers to the same file format. Listing them together helps maintain compatibility across tools.
