# Dataset Card for ESA Hubble Deep Space Images & Captions |
|
|
|
The ESA Hubble Deep Space Images & Captions dataset is composed primarily of Hubble deep space scans as high-resolution images, |
|
along with textual descriptions written by ESA/Hubble. Metadata is also included, which enables more detailed filtering and understanding of massive space scans. |
|
The purpose of this dataset is to enable text-to-image generation methods for generating high-quality deep space scans from prompts. |
|
|
|
## Examples |
|
|
|
 |
|
> A grazing encounter between two spiral galaxies: In the direction of the constellation Canis Major, two spiral galaxies pass by each other like majestic ships in the night. The near-collision has been caught in images taken by the NASA/ESA Hubble Space Telescope and its Wide Field Planetary Camera 2. |

|
|
 |
|
> The magnificent starburst galaxy Messier 82: This mosaic image of the magnificent starburst galaxy, Messier 82 (M82) is the sharpest wide-angle view ever obtained of M82. It is a galaxy remarkable for its webs of shredded clouds and flame-like plumes of glowing hydrogen blasting out from its central regions where young stars are being born 10 times faster than they are inside in our Milky Way Galaxy. |

|
> Extreme star cluster bursts into life in new Hubble image: The star-forming region NGC 3603 - seen here in the latest Hubble Space Telescope image - contains one of the most impressive massive young star clusters in the Milky Way. Bathed in gas and dust the cluster formed in a huge rush of star formation thought to have occurred around a million years ago. The hot blue stars at the core are responsible for carving out a huge cavity in the gas seen to the right of the star cluster in NGC 3603's centre. |

## Statistics |
|
|
|
* There are a total of 2,706 deep space images |
|
* The complete uncompressed size of the dataset is 120 GB, so definitely make use of [Streaming](https://huggingface.co/docs/datasets/stream) |
|
* The average image is 44 MB, while the max image size is 432 MB |
|
* The average image has a height of 2,881 pixels, and an average width of 3,267 pixels |
|

## Collection |
|
|
|
All images were collected from [https://esahubble.org/](https://esahubble.org/). |
|
Fullsize Original images & metadata were crawled from the ESA Hubble website using [Scrapy](https://scrapy.org/). |
|
Images were downloaded as `.tiff` files with the following [code](https://github.com/Supermaxman/SpaceGAN), while |
|
additional metadata was later collected for each image using the following [code](https://github.com/Supermaxman/WebbDiffuser). |
|
|
|
|
|
As the ESA Hubble website collects images from a wide variety of sources, images were filtered to try to avoid any non-space scan images as follows: |
|
The ESA Hubble [Advanced Image Search](http://esahubble.org/images/archive/search) enables the following filtering parameters: |
|
* images with Minimum size greater than or equal to 400x300 |
|
* Ranking greater than or equal to Fair or better |
|
* Type containing 'Observation' |
|
This reduced significantly the number of images which had nothing to do with Hubble deep space scans. |
|
A total of around 3,000 space images were collected with this method. |
|
|
|
|
|
## Filtering |
|
|
|
Further automatic and manual filtering was performed to remove the following: |
|
* improperly classified images |
|
* space renders |
|
* diagrams with text |
|
* images of celestial bodies within our solar system |
|
This brought the total number of deep space images down to 2,593. |
|
This process was not perfect, and there likely remain some images in the dataset that should be removed in the future. |
|
|
|
|
|
|
|
## Preprocessing |
|
|
|
Some of the deep space scans were as large as 34,372x19,345, with a bit depth of 24 (nearly 2 GB). |
|
Unfortunately, these images were too large to upload easily. |
|
Therefore, images were automatically subdivided in half if they were above 12,000 pixels in either height or width. |
|
Subdivided images were also tagged with additional metadata, such that users can reconstruct the original images if they would prefer. |
|
Otherwise, metadata was copied across subdivided images. |
|
This process resulted in 2,706 final deep space images. |
