we cant see it through space telescope because of the nearby intense star.Then how they detect it??

the orbit of both would be altered at intervals because of gravitational pull,the mass of both can be calculated by their effect on each other

Planets in other galaxies are far beyond our present capabilities. We can detect planets only around nearby stars in our own galaxy. Even those planets can't be seen directly. Most of them are detected by the slight wobble caused by the gravitational pull of the orbiting planet. They can pick this up by measuring the doppler shift of the star's spectral lines over time, using very sensitive spectrometers.

The star would "wobble" as the planet rotated around it. .This is caused by the gravity of both pulling on each other..The "wobble" can be calculated to figure the size of the planet
Good question.

We do not the ability to do this, other galaxies are far too distant to isolate individual stars in them.
