NGC 1073 is a barred spiral galaxy in the constellation Cetus.The galaxy is estimated to be about 55 million light years from Earth, possess a disk spanning an estimated 80,000 light years in diameter, and likely contains a type of active core, called an HII nucleus.
At 15:44:06 UT on 7 Mar 2023, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 230307A . [6] at the same time, the Gravitational Wave High-energy Electromagnetic Counterpart All-sky Monitor light curve shows a roughly fast rise and exponential decay (FRED) shape with a possible precursor, with a total duration of ~100 sec. [7] At 2023-03-07T15:44:09Z UT (Solar Orbiter onboard ...
Of several items, then called radio stars, Cygnus A was identified with a distant galaxy, being the first of many radio stars to become a radio galaxy. [24] [25] First quasar: 3C273: Virgo: 1962 3C273 was the first quasar with its redshift determined, and by some considered the first quasar. [citation needed] 3C48: Triangulum: 1960
For example, NGC 2914 (Arp 137) is merely a spiral galaxy with faint spiral arms, [14] and NGC 4015 (Arp 138) is an interacting pair of galaxies where one galaxy is an edge-on spiral galaxy. [15] Some objects, such as NGC 2444 and NGC 2445 ( Arp 143 ), are systems that contain "ring galaxies", which are created when one galaxy (the elliptical ...
