Astronomy and gravity

Research in astronomy seeks to understand the universe as a whole and the astronomical object in it such as black holes, stars and planets. A cornerstone for obtaining this understanding is gravity which holds some of the most profound ridles in fundamental physics.

Selection of the first image of a black hole, using Event Horizon Telescope observations of the center of the galaxy M87. The image shows a bright ring formed as light bends in the intense gravity around a black hole that is 6.5 billion times more massive than the Sun.

Astronomy, astrophysics and gravity

Gravity is a force that everyone knows from their everyday life 鈥� and yet it holds some of the most profound riddles in physics, for instance how it fits with quantum physics. It also shapes the properties of some of the most extreme objects in our universe, like black holes and neutron stars, that are in the focus of astrophysics.
