Examples
“They [gamma rays] are produced by supernovae, neutron stars, galactic centres, black holes and the like.”
“The only known source of such intense magnetism in our own galaxy is the supermassive black hole Sagittarius A*, which sits at the Milky Way’s center. “Maybe this FRB source is in a similar environment, a galactic centre environment,” [Jason] Hessels said.”
“'Quasar' — short for quasi-stellar radio source — are bright galactic centres.”
“Scientists believe galactic centres could act as Schelling points for civilisations that cannot communicate among themselves.”
“This work had to be done by looking at infrared light. That’s because, at visual wavelengths, huge clouds of dust and gas obstruct our vision – we can only see about 10 per cent of the distance to the galactic centre in this way (Sagittarius A* is approximately 26,000 light years away).”
“If an advanced civilisation anywhere in the Milky Way wanted to put a beacon somewhere … the galactic centre would be a good place to do it.”
“They spread out from the galactic centre 25,000 light years from Earth like fragmented spokes on an enormous wheel.”
“'The options were a quasar-like outburst from the black hole at the Galactic Centre, or star-power — the hot winds from young stars, and exploding stars,' said team member Dr Gianni Bernardi of the Harvard-Smithsonian Center for Astrophysics, in Cambridge, Massachusetts. 'Our observations tell us it's star-power.' In fact, the outflows appear to have been driven by many generations of stars forming and exploding in the Galactic Centre over the last hundred million years.”
“3. The Galactic Centre / This image looks deeper into space to the centre of our Milky Way Galaxy.”
“It was especially challenging because of the haze of stars, dust, and gas in between Earth and the Galactic Centre, as well as the fact that the pattern of light from Sgr A* [Sagittarius A*] changed quickly, over the course of minutes.”
“'Our unprecedented survey of a large part of the Galactic centre has given us detailed insights into the formation process of stars in this region of the Milky Way,' said author Rainer Schödel of the Institute of Astrophysics of Andalusia in Spain.”
“The Galactic centre was already shining high in the sky, with the zodiacal light beautifully complementing it on the right.”
““Our discovery lets us speculate about the presence of planets, since these are often formed around young stars. It seems plausible that the detection of planets in the Galactic centre is just a matter of time,” said Florian Peißker, a researcher at the University of Cologne, Germany, and lead author of the new study.”
