Protoplanetary Disk tagged posts
Researchers have discovered that carbonaceous chondrites, a class of meteorites, incorporated hydrated minerals along with organic material from the protoplanetary disk before the formation of planets. Scientists from the study published in the journal Space Science Reviews note that these meteorites played “an important role in the primordial Earth’s water enrichment” because they facilitated the transportation of volatile elements that were accumulated on the external regions of the so-called protoplanetary disk from which planets were formed more than 4.500 years ago. Earth was formed in an environment close to the Sun, very much reduced due to the relative lack of oxygen.

Read MoreThe dusty disk surrounding star TW Hydrae exhibits circular features that may signal the formation of protoplanets. An astrophysicist argues, however, that the innermost actually points to the impending dispersal of the disk. When the maps appeared at the end of March, experts were electrified. The images revealed an orange-red disk pitted with circular gaps: a detailed portrait of a protoplanetary disk, made up of gas and dust grains, associated with a young star – the kind of structure out of which planets could be expected to form...
