    Welcome to RGZ, sergey667! 😃

    In terms of radio morphology (just a fancy word for 'shape'), it's a #compact source. In the IR - from WISE, that's what the background orange-yellow-white is - it's a 'point souce' (i.e. it shows no sign of being spread out, as a nearby galaxy would, for example). In the optical (or 'visual', the word astronomers use for that part of the electromagnetic spectrum ~the same as what our eyes can see), it looks like a blue star (SDSS J073256.27+254838.7 is it's name):

    In fact, it's a quasar (or QSO), with a redshift of 1.443! 😮 QSOs are the extraordinarily bright cores (nuclei) of (nearly always) very distant galaxies.

    Astronomy is fun, isn't it?

    Happy hunting! 😄
