Although the spiral is tilted away from us, with only a thin sliver in view, such a perspective can be advantageous for astronomers. For instance, astronomers have previously used the high inclination of this spiral to study the properties of the halo of hot gas[4] that is visible when the galaxy is observed at X-ray wavelengths. Interaction with NGC 5774NGC 5775 is interacting with the nearby galaxy NGC 5774 in the form of two connecting H I bridges through which the gas is travelling from NGC 5774 to NGC 5775.[5] Faint optical emission as well as radio continuum emission are also present along the bridges.[11] It is possible that star formation is occurring between the galaxies.[5] This system may be in the early stages of a merger.[6] External links
