At present, no problems.
15 years ago, scientists had no explanation for the small number of solar neutrinos detected at our Earth. Either we didn't understand neutrino formation in our Sun, our detectors were wrong, or neutrinos had the capacity to decay. The latter seemed to be the least likely possibility, so scientists argued for many years which of the first two was correct.
In 1998 it was discovered that neutrinos do, indeed, decay into other neutrinos. The reason we weren't seeing as many neutrinos as we expected was because the ones we were expecting to see had decayed into other types. So the solar neutrino problem is no longer a problem.
Modern astronomy.
Yes, Kepler's laws of planetary motion are still used in modern astronomy to describe the motion of planets and other celestial bodies in our solar system. Kepler's model provides a foundation for understanding orbits and predicting the positions of planets accurately.

Astronomy as a scientific field was born out of early civilizations' observations of celestial bodies and their movements. Ancient astronomers such as the Babylonians and Greeks studied the stars, planets, and the motion of celestial objects, which laid the foundation for modern astronomy. Over time, developments in technology, such as the invention of the telescope, further advanced our understanding of the universe.
The Italian who first used a telescope to study astronomy was Galileo Galilei, born in 1564, the same year as William Shakespeare. Galileo is renowned for his significant contributions to observational astronomy, including the discovery of the moons of Jupiter and the phases of Venus. His work laid the foundation for modern physics and astronomy, challenging the geocentric model of the universe.
Modern Astronomy is the astronomy in which we actually started looking at celestial bodies up close. Today there is a lot going on about the information of astronomy. Galileo was the first modern astronomer, just an interesting fact to throw in!
