Muhtasari

Maelezo
English: This is the first image of Sgr A*, the supermassive black hole at the centre of our galaxy. It’s the first direct visual evidence of the presence of this black hole. It was captured by the Event Horizon Telescope (EHT), an array which linked together eight existing radio observatories across the planet to form a single “Earth-sized” virtual telescope. The telescope is named after the event horizon, the boundary of the black hole beyond which no light can escape. Although we cannot see the event horizon itself, because it cannot emit light, glowing gas orbiting around the black hole reveals a telltale signature: a dark central region (called a shadow) surrounded by a bright ring-like structure. The new view captures light bent by the powerful gravity of the black hole, which is four million times more massive than our Sun. The image of the Sgr A* black hole is an average of the different images the EHT Collaboration has extracted from its 2017 observations.
Français : Voici la première image de Sgr A*, le trou noir supermassif au centre de notre galaxie. C'est la première preuve visuelle directe de la présence de ce trou noir. Elle a été capturée par l'Event Horizon Telescope (EHT), un réseau qui a relié huit observatoires radio existants sur la planète pour former un seul télescope virtuel de la taille de la Terre. Le télescope porte le nom de l'horizon des événements, la limite du trou noir au-delà de laquelle aucune lumière ne peut s'échapper. Bien que nous ne puissions pas voir l'horizon des événements lui-même, car il ne peut pas émettre de lumière, le gaz incandescent qui orbite autour du trou noir révèle une signature caractéristique : une région centrale sombre (appelée ombre) entourée d'une structure annulaire brillante. La nouvelle vue capture la lumière déviée par la puissante gravité du trou noir, qui est quatre millions de fois plus massif que notre Soleil. L'image du trou noir Sgr A* est une moyenne des différentes images que la collaboration EHT a extraites de ses observations de 2017.
