SN W49b Facts

SN W49b Facts Supernova Remnant in Aquila

SN W49b is a supernova remnant object of interest in space. It lies at a distance of about 33,000.00 light years away in the constellation of Aquila.

The Supernova Remnant's location is 19h 11m 09s (R.A.) and +09:06:24 (Dec.).

Unlike other supernovae that we have looked at, this supernova explosion left behind a black hole and not a neutron star which other supernova explosions have created. Its not unique in creating a black hole but it is believed to be the youngest. Another example of a black hole created by a supernova is SS443 which is also in the Aquila constellation. The explosion occurred recently, a mere youngling at 1000 years ago. Given that the universe is around 13.8 billion years old, you can understand why its quite recent in astronomical terms.

When supernovae explode, the gamma rays and explosions emmanate out from the centre. SN W49B is different because the explosion expanded out from the poles rather than equator.

The size of the original star is believed to have a mass of more than 25 times that of the Sun. The star would be in the larger scale of stars in the galaxy. I did read once but I can't find the source that the Sun although classified as a main sequence dwarf star is bigger than 70% of stars in the galaxy.

Travel Time to SN W49b

The time it will take to travel to this star is dependent on how fast you are going. U.G. has done some calculations as to how long it will take going at differing speeds. A note about the calculations, when I'm talking about years, I'm talking non-leap years only (365 days).

The New Horizons space probe is the fastest probe that we've sent into space at the time of writing. Its primary mission was to visit Pluto which at the time of launch (2006), Pluto was still a planet.
