Planet-hunting telescopes seize intriguing view of Centaurus A – Astronomy Now

August 1, 2019 - Comment

The 4 1-metre SPECULOOS telescopes on the Paranal Observatory in Chile, designed to Seek for liveable Planets EClipsing ULtra-COOL Stars, captured this spectacular view of Centaurus A (NGC 5128), a galaxy 11 million gentle years from Earth that harbours a 100-million-solar-mass black gap at its core. Found in 1826, it’s the closest energetic galactic nucleus


The 4 1-metre SPECULOOS telescopes on the Paranal Observatory in Chile, designed to Seek for liveable Planets EClipsing ULtra-COOL Stars, captured this spectacular view of Centaurus A (NGC 5128), a galaxy 11 million gentle years from Earth that harbours a 100-million-solar-mass black gap at its core. Found in 1826, it’s the closest energetic galactic nucleus and a well-recognized goal for skilled and novice astronomers alike. Researchers attribute the galaxy’s uncommon look to a collision within the distant previous between an elliptical galaxy and a smaller spiral. This picture exhibits purple and pink star-forming areas and clusters of younger blue stars at prime proper. The huge mud clouds in direction of the centre of Centaurus A are slowly being consumed by the central black gap, leading to highly effective radio emissions.

The SPECULOOS telescopes had been designed to survey as much as 10 instances extra purple dwarf stars than the European Southern Observatory’s pioneering TRAPPIST telescope at La Silla, which has been searching for exoplanets since 2011. A statistical evaluation signifies SPECULOOS will discover at the very least 12 multi-planet photo voltaic techniques comparable in dimension to the TRAPPIST-1 system, which options at the very least seven terrestrial worlds.
