With the help of upgraded technology, Harvard astronomers have detected Pluto-sized objects moving forward with the sun. The astronomers put Atacama Large Millimeter/submillimeter Array in use for their stint, helping them discover these objects that are now believed to have close relations with stars. Researchers keep a watch on star HD 107146 and the protoplanetary disk that surrounds it by using this sophisticated instrument.
Researchers have made preparations to soon publish new observations in the Astrophysical Journal. A rise in the amount of dust particles was visible to scientists in the outer rings of the disk, a clear evidence for the creation of new Pluto-sized planetesimals.
