The Crab Nebula is a pulsar wind nebula associated with the 1054 supernova.It is located about 6,500 light-years from the Earth. [1]A near-Earth supernova is an explosion resulting from the death of a star that occurs close enough to the Earth (roughly less than 10 to 300 parsecs [30 to 1000 light-years] away [2]) to have noticeable effects on Earth's biosphere.
A light year is the distance light travels in a year, 5.9 trillion miles (9.5 trillion km). ... Firefly Sparkle is located about 6,500 light-years from Firefly-Best Friend and about 42,000 light ...
A light year is the distance light travels in a year, 5.9 trillion miles (9.5 trillion km). ... circumstellar disks had been detected only within about 6,500 light years of Earth.
It was initially identified as a planetary nebula, and its distance was estimated to be approximately 6500 light-years away from Earth. [8] However, recent results suggest that this object is a young star surrounded by a protoplanetary disk, at a distance of about 900 light-years away. [4] [9]
Discovered in 1988, it is located roughly 6,500 light-years (2,000 parsecs) away from Earth. It orbits with a brown dwarf or Super-Jupiter companion with a period of 9.2 hours with an eclipse duration of approximately 20 minutes. When it was discovered, it was the first such pulsar known. [1]
IRAS 22036+5306, also known as 2MASS J22053028+5321327, is a protoplanetary nebula located in the constellation Cepheus at approximately ~6,500 light-years from Earth. [2] [1] The nebula was created by the shedding of most of the material in the outer shell of an aging star. The gas cloud formed is heated by the still burning hot core of the ...
It is heading in the direction of the sun at 4.9 kilometers (3 miles) a second. [4] Distances to all but a few planetary nebulae are notoriously difficult to determine; older estimates put NGC 6565 at 6500 light-years, and newer estimates place it at up to 15,000 light-years .
NGC 6751, like all planetary nebulae was formed when a dying star threw off its outer layers of gas several thousand years ago. It is estimated to be around 0.8 light-years in diameter. [6] NGC 6751 has a complex bipolar structure. There is a bright, inner bubble (shown in the photo), as well as two fainter halos.
