FITS Format Liberation - DIY Astronomical Images With The Expert Touch

08.07.2004


This previously unreleased colour image of the planetary nebula NGC 5979 was combined from raw FITS files with the ESA/ESO/NASA Photoshop FITS Liberator. In the top row the raw greyscale images are seen. Four individual exposures were combined to form this colour image and the colour filters for the individual exposures are indicated. The number refers to the colour;; or wavelength;; of light that the filter allows through. This is measured in nanometres (a millionth of a millimetre). The N’s and W’s in the filter name refer to whether the filter is a narrow-band (N) or a wide-band filter (W). The second row shows the individual exposures after a colorising layer has been applied in Photoshop. Image credit: ESA;; ESO and NASA


For many years astronomical images from the world’s telescopes were reserved for an elite of astronomers and technical people. Now anyone with a desktop computer running Adobe® Photoshop® software can try their hand at crafting astronomical images as beautiful as those from the Hubble Space Telescope. A free software plug-in, released today, makes a treasure trove of archival astronomical images and spectra from the NASA/ESA Hubble Space Telescope, the European Southern Observatory’s Very Large Telescope, the European Space Agency’s XMM-Newton X-ray observatory, NASA’s Spitzer Space Telescope and many other famous telescopes accessible to home astronomy enthusiasts.

If there is anything that unites astronomy, it is the worldwide use of a single file format - nearly all the images of stars and galaxies produced by telescopes on the ground and in space are stored as so-called FITS files. Unfortunately this file format has been accessible to very few people other than professional scientists using highly specialised image-processing tools.

Now a new and unique tool - the ESA/ESO/NASA Photoshop FITS Liberator – developed by imaging scientists at the European Space Agency, the European Southern Observatory and NASA makes the immense wealth of astronomical images and spectra stored in data archives around the world accessible to the layman. The only thing required is access to either Adobe Photoshop® or Adobe Photoshop Elements®, both leading image software packages.



For the professional creators of astronomical colour images, the plug-in revolutionises the workflow of the creation of colour images from raw data and gives a huge boost to the image quality by giving access to the full 16 bit (65536 colours) range of the observations. In addition the plug in may be used as a powerful educational tool when teaching about light, colour and digital images. Some examples of educational material are available at the web page below.

The ESA/ESO/NASA Photoshop FITS Liberator will be released today and is freely available for download from:

Head of the development team, Lars Holm Nielsen from Denmark, says, “FITS is much more than just an image format. It is an extremely flexible file format that allows astronomers to share images and spectra in many different ways. This very versatility has made the job of producing a plug-in for Photoshop challenging. Compared to formats like JPEG, FITS files can be incredibly diverse.”

Im Focus: Lethal combination: Drug cocktail turns off the juice to cancer cells

A widely used diabetes medication combined with an antihypertensive drug specifically inhibits tumor growth – this was discovered by researchers from the University of Basel’s Biozentrum two years ago. In a follow-up study, recently published in “Cell Reports”, the scientists report that this drug cocktail induces cancer cell death by switching off their energy supply.

The widely used anti-diabetes drug metformin not only reduces blood sugar but also has an anti-cancer effect. However, the metformin dose commonly used in the...

Im Focus: New Foldable Drone Flies through Narrow Holes in Rescue Missions

A research team from the University of Zurich has developed a new drone that can retract its propeller arms in flight and make itself small to fit through narrow gaps and holes. This is particularly useful when searching for victims of natural disasters.

Inspecting a damaged building after an earthquake or during a fire is exactly the kind of job that human rescuers would like drones to do for them. A flying...

Im Focus: Researchers develop method to transfer entire 2D circuits to any smooth surface

What if a sensor sensing a thing could be part of the thing itself? Rice University engineers believe they have a two-dimensional solution to do just that.

Rice engineers led by materials scientists Pulickel Ajayan and Jun Lou have developed a method to make atom-flat sensors that seamlessly integrate with devices...
