Hubble Images a Starstruck Galaxy
Talk about stealing the spotlight! ⭐
The irregular galaxy Arp 263 lurks in the background of this image from the NASA/ESA Hubble Space Telescope, but the view is dominated by a stellar photobomber, the bright star BD+17 2217. Arp 263 – also known as NGC 3239 – is a patchy, irregular galaxy studded with regions of recent star formation, and astronomers believe that its ragged appearance is due to its having formed from the merger of two galaxies. It lies around 25 million light-years away in the constellation Leo.
The interloping foreground star, BD+17 2217, is adorned with two sets of crisscrossing diffraction spikes. The interaction of light with Hubble’s internal structure means that concentrated bright objects, such as stars, are surrounded by four prominent spikes. Since this image of BD+17 2217 was created using two sets of Hubble data, the spikes from both images surround this stellar photobomber. The spikes are at different angles because Hubble was at different orientations when it collected the two datasets.
