New stars, different planetary designs, new celestial bodies, new moons, etc.
Astronomers used observational and mathematical skills to discover Neptune. They observed irregularities in the orbit of Uranus and calculated the gravitational influence needed to explain these irregularities, leading them to predict and discover the existence of Neptune.
As of my last update, astronomers have not discovered a new planet in our solar system. However, new exoplanets outside our solar system are routinely being discovered using various observational techniques.
Ptolemy did not discover any planets. He lived in the 2nd century AD and his work primarily focused on developing mathematical models to explain the motion of the planets as observed from Earth. The discovery of the planets we now know was made by astronomers in different time periods.
Astronomers use various methods to discover extrasolar planets, also known as exoplanets. These methods include the transit method (detecting a planet as it passes in front of its star), the radial velocity method (detecting a wobble in a star's motion caused by an orbiting planet), direct imaging (taking pictures of exoplanets), and gravitational microlensing (observing the bending of light from a distant star due to a foreground planet).
Rocks are to geologists as stars are to astronomers.

Yes when technologgy improves
omg y wont it give me the answer
yes they do because one day they may discover it
A freaking telescope

There is no limit for a salary or the payment for an astronomer. The bigger you discover, the more you get paid. So there is no limit.
An elliptical galaxy
Astronomers discover black holes in the universe by observing the effects they have on nearby objects, such as stars and gas. They use telescopes to detect X-rays and other forms of radiation emitted by black holes, as well as studying the gravitational influence they have on surrounding matter.
Astronomers had noticed unexpected changes in the orbit of Uranus: the only explanation was another planet. Detailed study of the orbit of Uranus led to estimates about the size and location of Neptune.
