Only since 2015 have we been able to observe these invisible astronomical bodies, which can be detected only by their gravitational attraction. The history of our hunt for these enigmatic objects traces back to the 18th century, but the crucial phase took place in a suitably dark period of human history - World War II.

Loop quantum gravity is opening up a new paradigm in modern physics. The theory has emerged as a leading candidate to analyze extreme cosmological and astrophysical phenomena in parts of the universe, like black holes, where the equations of general relativity cease to be useful.

An international team of astronomers using a combination of ground and space based telescopes have reported more than 100 extrasolar planets in only three months. These planets are quite diverse and expected to play a large role in developing the research field of exoplanets and life in the Universe.

Based on computer simulations and new observations, researchers have found that the rings of gas surrounding active supermassive black holes are not simple donut shapes. Instead, gas expelled from the center interacts with infalling gas to create a dynamic circulation pattern, similar to a water fountain in a city park.
