* Stars: Stars are massive celestial objects that emit light and heat due to nuclear fusion reactions occurring in their cores. They exist in outer space, far beyond the Earth's atmosphere.

* Stratosphere: This is a layer of Earth's atmosphere that sits above the troposphere (where we live). It is known for its ozone layer, which absorbs harmful ultraviolet radiation from the sun. There are no stars in the stratosphere.

* Mesosphere and Thermosphere: These are layers of Earth's atmosphere that are higher than the stratosphere.

* Mesosphere: This layer is characterized by decreasing temperatures and is where most meteors burn up.

* Thermosphere: This is the outermost layer of the atmosphere, characterized by very high temperatures.

So, to answer your questions:

* Are there stars in the stratosphere? No, stars are much too far away and exist outside the Earth's atmosphere.

* Are mesosphere and thermosphere the same? No, they are distinct layers of Earth's atmosphere. The thermosphere is above the mesosphere.

It's important to remember that stars are not part of Earth's atmosphere. They are celestial objects that we observe from Earth.
