How to get rid of these spots

I have a Sony RX10iv and love it.  Have been shooting some night sky shots at iso 3200 and 20 sec exposures.  Lately, I thought that taking a long exposure with the lens cap on would give me an idea of the noise being generated by the sensor.  What appeared was about 10 white dots that looked like some kind of sky shot.  They are there in iso 3200 and iso 100, jpeg and raw as well.  Any idea what they are and if they can be removed from the camera.  I have included a jpeg captured with the raw.  The dots look like they are several pixels wide Thanks Caseyjay
