The supernova was about 21 million light-years from Earth and is expected to have left behind either a neutron star or black hole, based on current stellar evolution models. The supernova is located near a prominent HII region, NGC 5461, in an outer spiral arm of the bright galaxy. [3] By 22 May 2023, SN 2023ixf had brightened to about ...
SN 1006 was a supernova that is likely the brightest observed stellar event in recorded history, reaching an estimated −7.5 visual magnitude, [3] and exceeding roughly sixteen times the brightness of Venus.
Insets at lower right show one epoch of Webb observations, while the inset at left shows a Webb image of the central supernova remnant released in 2023. "Even as a star dies, its light endures ...
A rare nova explosion will soon be visible in the Earth’s nighttime sky, according to officials at NASA. The event, which could occur anytime between now and September, is creating a buzz within ...
“The detail we can now see is astonishing, comparable to seeing a person on the Moon,” he said. “But what’s more, we caught it when it must have just done something dramatic.
The expanding cloud of material left over from the supernova now appears approximately 10 light-years (3 pc) across from Earth's perspective. It has been seen in wavelengths of visible light with amateur telescopes down to 234 mm (9.25 in) with filters.
A nova, a rare astronomical event, could be visible soon. It won't last long, and it won't occur again for several decades. How to see it in 2024.
SN 2023rve is a type II supernova that happened in the 10th magnitude barred spiral galaxy NGC 1097 on September 8, 2023. [1] Scientists from the McDonald Observatory in the state of Texas, United States, have observed the supernova and conducted photometric measurements, they described it to be the brightest supernova in the sky as of September 12, 2023.
