NGC 7331, also known as Caldwell 30, is an unbarred spiral galaxy about 40 million light-years (12 Mpc) away in the constellation Pegasus. It was discovered by William Herschel on 6 September 1784. [4] The galaxy appears similar in size and structure to the Milky Way, and is sometimes referred to as "the Milky Way's twin". [5]
GRB 211106A, one of the most energetic sGRB ever registered, in the first-ever time-lapse movie of a GRB in millimeter-wavelength light, as seen by the Atacama Large Millimeter/ submillimeter Array (ALMA) [64] [65] [66] Events with a duration of less than about two seconds are classified as short gamma-ray bursts (sGRB).
The brightest gamma ray burst ever detected recently reached Earth. It’s 70 times longer than any other burst we’ve spotted.
GRB 080319B was a gamma-ray burst (GRB) detected by the Swift satellite at 06:12 UTC on March 19, 2008. The burst set a new record for the farthest object that was observable with the naked eye: [2] it had a peak visual apparent magnitude of 5.7 and remained visible to human eyes for approximately 30 seconds.

Abell 2390 is a massive galaxy cluster located in the constellation Pegasus. [4] It is classified as an X-ray and rich galaxy clusters measured cooling rate of 200-300 M ʘ yr −1 . [ 5 ] The galaxy cluster contains a cD galaxy called Abell 2390 BCG (short for brightest cluster galaxy), associated with a complex radio source , B2151+141.
A2261-BCG (short for Abell 2261 Brightest Cluster Galaxy) is a huge elliptical galaxy in the cluster Abell 2261. One of the largest galaxies known, A2261-BCG is estimated to have a diameter of a million light-years, some 10 times larger than the Milky Way. It is the brightest and the most massive galaxy in the cluster, and has one of the ...
