This is a continuation of a project I started about 2,5 years ago when I worked on a mosaic of Messier 106, made using images of the Hubble Space Telescope. In 2015 I found some new data sources on the internet, including some huge telescope databases with data from professional telescopes. That’s when I decided …
Full resolution on Flickr Published on Bad astronomy blog About 2 years ago I worked on a mosaic of Messier 106, made using images of the Hubble Space Telescope.

Recently I started working on crawling through some science databases of several large telescopes to see what data can be found in these archives. Some of the most interesting archives I found are, amongst others, the Subaru Telescope, the Gemini Telescopes, the Canadian-French-Hawaii-Telescope (CFHT) and of course the Hubble Legacy Archive. This image shows …
Last night we had a great lecture from Hanny Van Arkel at the Vereniging Christiaan Huygens in Papendrecht. She discovered a new kind of astronomical object in 2007 using the Galaxy Zoo. The class of objects is now called officially ´Hanny´s voorwerp (HsV)´ which is a great achievement I think. One hypothesis suggests that HsV …
On the 23rd of May 2013 NASA released a new image from the Hubble Space Telescope and the Large Binocular Telescope showing the outskirts of M57, the Ring Nebula. The same dataset was used as I used for my previous processing of M57. As this was based on comparable data I decided to combine this …
This image shows a combination of visible light imagery of the Hubble Space telescope and infrared data from the Spitzer space telescope of M51, aka the Whirlpool galaxy. The Whirlpool Galaxy (also known as Messier 51a, M51a, or NGC 5194) is an interacting grand-design spiral galaxy that is estimated to be 23 ± 4 million …
Recently I have been working on Hubble data of M57. When processing the data I found one of the stars moving between the images. Triggered by this I tried to find more data that could show the motion. I found some old images made in 1922 and around 1959 made by a 100-inch and a …
This image was the result of combining my Hubble image created from 2011 WFC3 data and data from the Subaru Telescope (8.2m) in Hawaii, processed by Robert Gendler. He kindly shared the data and the final result is an astonishing image showing the outer shells of the M57 planetary nebula. More info about this nebula …
This image shows the most detailed image taken of M57, until present day. The famously named “Ring Nebula” (also catalogued as Messier 57, M57 or NGC 6720) appears in the northern constellation of Lyra and is located in the Carina–Sagittarius Arm. It is one of the most prominent examples of a planetary nebula, the gaseous …
Hubble imagery of NGC 3256. Galaxies don’t normally look like this. NGC 3256 actually shows a current picture of two galaxies that are slowly colliding. Quite possibly, in hundreds of millions of years, only one galaxy will remain. Today, however, NGC 3256 shows intricate filaments of dark dust, unusual tidal tails of stars, and a …
