Astrobiology, formerly kenned as exobiology, is an interdisciplinary scientific field concerned with the inchoations, early evolution, distribution, and future of life in the macrocosm. Astrobiology considers the question of whether extraterrestrial life subsists, and if it does, how humans can detect it. Astrobiology makes utilization of molecular biology, biophysics, biochemistry, chemistry, astronomy, physical cosmology, exoplanetology and geology to investigate the possibility of life on other worlds and avail agnize biospheres that might be different from that on Earth. The inchoation and early evolution of life is an inseparable part of the discipline of astrobiology. To increase the visibility and ease of use of open access scientific and scholarly journals top online publishing journals are indexed in different indexing and archiving services. Indexing provides easy access of the article online. The top online publishing journals publish articles which are cited as references by many authors in their work. Citations are important for a journal to get impact factor. Impact factor is a measure reflecting the average number of citations to recent articles published in the journal. The impact of the journal is influenced by impact factor, the journals with high impact factor are considered more important than those with lower ones. Indexing provides easy access of the article online. The international journals are among the best open access journals in the world, set out to publish the most comprehensive, relevant and reliable information based on the current research and development on a variety of subjects. This information can be published in our peer reviewed journal with impact factors and are calculated using citations not only from research articles but also review articles (which tend to receive more citations), editorials, letters, meeting abstracts, short communications, and case reports. The inclusion of these publications provides the opportunity for editors and publishers to manipulate the ratio used to calculate the impact factor and try to increase their number rapidly. Impact factor plays a major role for the particular journal. Astrobiology-group-journals-list works to publish most reliable and complete source of information regarding advance discoveries and development in the path of astrobiology.
