Quasars are some of the brightest objects in the universe. They are also some of the rarest as astronomers have a hard time finding them. However a number of quasars have recently been found. Quasars are some of the most distant objects known, which makes them close to the time the universe was formed.
Quasars are some of the most mysterious objects of our universe. Until now most astronomers cannot fully define what they are. Quasars though emit a large and uniform amount of radiation and light, making them very bright. They are also found near supermassive black holes.
A team of astronomers led by Carnegie Institution researcher Eduardo Banados has found 63 new quasars. The 63 new quasars come at a time when the universe was still 1 billion years old. As Phys Org reports, the universe is now 14 billion years old. The amount of quasars found is almost double the number of ancient quasars known.
Finding such quasars is difficult since they are so far away, though finding them could be very important as these quasars have been present near at the time the universe was formed. They could then provide much information about how the universe was once astronomers study them more thoroughly.
"The formation and evolution of the earliest light sources and structures in the universe is one of the greatest mysteries in Astronomy," Banados says. Quasars are called relics of the universe since they provide a glimpse of an early time, Science Alert says.
These quasars are from a time period when the universe started to cool down. For millions of years the universe was a hot place, and when it started to cool down one of the first objects to appear were the quasars. Some of the quasars then predate many galaxies and stars. Now with new quasars added, scientists might have more material to study from and gain more understanding of our universe.
While astronomers look at quasars, iTechPost also reports of a star that allows them to see its evolution in real time.
