26 million light-years, then we'll stick with megaparsec as the record-holder.
From these two data triangle can be set up that gives the distance to the galaxy, in this case 19 megaparsecs.
Recently reported distances range from 4 to 29 megaparsecs, but using this new method the researchers calculated the distance of 19 megaparsecs to the supermassive black hole.
BOSS observations show that the preferred distance between two galaxies is about 150 megaparsecs (roughly 450
We believe they could provide the first direct stellar distance measurements to galaxies in the range of 50-100 megaparsecs [150,000,000-326,000,000 light-years] and well beyond that," Stanek suggests.
David selected target galaxies in the magnitude range 12-15 and closer than 150 megaparsecs with the intention that a supernova would hopefully be bright enough to record, but in galaxies which, in many cases, were not intensively covered by other observers.
4 Megaparsecs away - the closest one in the last 25 years.
7 billion light years or 530 megaparsecs from Earth --their results gave around 15% error.
Such bursts would be rare and comefrom long distances, more than 100 megaparsecs away.
The presumed black hole resides in the center of the Seyfert galaxy NGC 5548, which lies some 70 megaparsecs or 200 million light-years from earth.
