This week’s imageThe Hubble Space Telescope has shown two of three interconnected galaxies, Arp 248, from its Hubble Space Telescope. This group, also known as Wild’s Triplet, consists of three small spiral galaxiesthat are linked together by bridges of stars.
The trio is located 200 million light years away in the constellation Virgo. They are named after Paul Wild, an Australian astronomer who was a leading solar researcher who studied the group in 1950s.
Interacting galaxyes are galaxies whose gravity fields affect each other. In this case, the gravity binding has led to bright bridges visible stretching between the two galaxies. The starlight from the bridge and the dust that it contains creates a tidal trail, which is formed by the pull between galaxies.
Hubble shared several images of interconnected galaxies in recent weeks, including Two other interconnected spiral galaxiesThe gravitational effects of their gravitational interactions on each other are subtler, as well as a pair or galaxies. They look as if they are inter-actingThey are not actually overlapping, as they are closer to each other. A video capturing the drama of galaxies merging is available. Amazing image taken by the Gemini North telescopeOr in a recent James Webb imageThis shows the bright effects from a merger in infrared.
