Size comparison of the event horizons of the black holes of TON 618 and Phoenix A.The orbit of Neptune (white oval) is included for comparison. As a quasar, TON 618 is believed to be the active galactic nucleus at the center of a galaxy, the engine of which is a supermassive black hole feeding on intensely hot gas and matter in an accretion disc.
Porphyrion is a Fanaroff–Riley class II radio galaxy located 7.5 billion light years away from Earth, with host galaxy J152932.16+601534.4.It is located in the constellation Draco and it was discovered in Low-Frequency Array (LOFAR) data by an international team led by Martijn Oei. [2]
3C 66B is an elliptical radio galaxy [6] [9] located in the constellation Andromeda. With an estimated redshift of 0.021258, [ 2 ] the galaxy is about 240.7 Mly (73.79 Mpc ) away. [ 3 ] It has an angular separation of 6 ′ from the blazar 3C 66A , [ 9 ] but the two are most likely unrelated.
4C +37.11 or Galaxy 0402+379 is a radio galaxy and elliptical galaxy featuring binary supermassive black holes with the least separation of any directly observed binaries, as of 2006. The separation between the two is 24 light-years or 7.3 parsecs , with an orbital period of 30,000 years.
A foxhole radio is a makeshift radio that was built by soldiers in World War II for entertainment, to listen to local radio stations using amplitude modulation. [ 1 ] [ 2 ] They were first reported at the Battle of Anzio , Italy, spreading later across the European and Pacific theaters .
Sagittarius A (Sgr A) is a complex radio source at the center of the Milky Way, which contains a supermassive black hole.It is located between Scorpius and Sagittarius, and is hidden from view at optical wavelengths by large clouds of cosmic dust in the spiral arms of the Milky Way.
Night 3 of Season 27’s Blind Auditions on The Voice had not one, but two four-chair turns. The second being BDii (Brian Darden II), 31, originally from Hampton, VA now of Atlanta, GA, who closed ...
VLBI radio observations of 3C 273 have revealed proper motion of some of the radio emitting regions, further suggesting the presence of relativistic jets of material. [12] [13] This is a prototype of an Active Galactic Nucleus, demonstrating that the energy is being produced through accretion by a supermassive black hole (SMBH).
