Diffraction spikes are lines radiating from bright light sources, causing what is known as the starburst effect [1] or sunstars [2] in photographs and in vision. They are artifacts caused by light diffracting around the support vanes of the secondary mirror in reflecting telescopes , or edges of non-circular camera apertures , and around ...
Messier 82 (also known as NGC 3034, Cigar Galaxy or M82) is a starburst galaxy approximately 12 million light-years away in the constellation Ursa Major.It is the second-largest member of the M81 Group, with the D 25 isophotal diameter of 12.52 kiloparsecs (40,800 light-years).
"The solar array light reflections were so mind blowing that I stayed up till 1AM to shoot a few more sunrises. Luckily we get sunrises every 90 minutes," Dominick wrote.
The massive black holes in ELIRGs could be absorbing matter for a longer time. Twenty new ELIRGs, including the most luminous galaxy found to date, have been discovered. These galaxies were not found earlier because of their distance, and because dust converts their visible light into infrared light.

Although supernovae are generally associated with starburst galaxies, only one has been detected within the Sculptor Galaxy. SN 1940E (type unknown, mag. 14) [18] was discovered by Fritz Zwicky on 22 November 1940, located approximately 54″ southwest of the galaxy's nucleus. [19] NGC 253 is close enough that classical novae can also be detected.
The last glint of sunlight appears on the edge of the moon just before the start of the total solar eclipse on April 8, 2024 near Fredericksburg, Texas.
The Antennae Galaxies are an example of a starburst galaxy occurring from the collision of NGC 4038/NGC 4039. Credit: NASA/ESA. A starburst galaxy is one undergoing an exceptionally high rate of star formation, as compared to the long-term average rate of star formation in the galaxy, or the star formation rate observed in most other galaxies.
