The abnormal galaxy Arp 263 lurks within the background of this symbol from the NASA/ESA Hubble Area Telescope, however the view is ruled via a stellar photobomber, the intense megastar BD+17 2217. Arp 263—often referred to as NGC 3239—is a patchy, abnormal galaxy studded with areas of new megastar formation, and astronomers consider that its ragged look is because of its having shaped from the merger of 2 galaxies. It lies round 25 million light-years away within the constellation Leo.
Two other Hubble investigations into Arp 263, the usage of two of Hubble’s tools, contributed knowledge to this symbol. The primary investigation used to be a part of an effort to watch the websites of new supernovae, such because the supernova SN 2012A that used to be detected simply over a decade in the past in Arp 263. Astronomers used Hubble’s tough Vast Box Digital camera 3 to seek for lingering remnants of the colossal stellar explosion. The second one investigation is a part of a marketing campaign the usage of Hubble’s Complex Digital camera for Surveys to symbol all of the up to now unobserved extraordinary galaxies within the Arp catalog, together with Arp 263, in an effort to in finding promising topics for additional learn about the usage of the NASA/ESA/CSA James Webb Area Telescope.
The interloping foreground megastar, BD+17 2217, is decorated with two units of crisscrossing diffraction spikes. The interplay of sunshine with Hubble’s interior construction signifies that concentrated shiny gadgets, comparable to stars, are surrounded via 4 outstanding spikes. Since this symbol of BD+17 2217 used to be created the usage of two units of Hubble knowledge, the spikes from each photographs encompass this stellar photobomber. The spikes are at other angles as a result of Hubble used to be at other orientations when it gathered the 2 datasets.
