Seven new dwarf galaxies have been discovered by the astronomers at the Yale University using a new type of telescope.
While probing a nearby spiral galaxy, the astronomers unearthed the seven celestial bodies by the help of a new kind of telescope which is made by stitching together telephoto lenses.
The robotic telescope was designed by Pieter van Dokkum, chair of Yale’s astronomy department, in association with University of Toronto astronomer Roberto Abraham.
“I’m confident that some of them will turn out to be a new class of objects. I’d be surprised if all seven of them are satellites of M101,” van Dokkum said.
Eight telephoto lenses with special coatings that suppress internally scattered light are used in the Dragonfly Telephoto Array. This makes the telescope capable of detecting the low surface brightness of the newly discovered galaxies.
According to van Dokkum, similar kinds of lenses are used to cover the sporting events like the World Cup.
The astronomers believe they have found a septuplet of new galaxies that were earlier ignored or overlooked because of their diffuse nature.
The scientists say the ghostly galaxies were detected from the night sky when they made their first observations from the ‘homemade’ telescope.
According to them, the discovery of these celestial gifts came instantly in a relatively small section of sky.
The researchers are hopeful that the previously unseen galaxies may lead to the important insights into dark matter and help in understanding the evolution of galaxy in a better way.
The researchers say that there are predictions from galaxy formation theory about the need for a population of very diffuse, isolated galaxies in the universe.
According to them, these seven galaxies are likely the tip of the iceberg. They said that there are thousands of such galaxies in the endless space that we haven’t detected yet.
