This point basically marks the end of the solar atmosphere and beginning of the solar wind.<\/span><\/p>\n<table style=\"border-collapse: collapse; width: 100%;\">\n<tbody>\n<tr>\n<td style=\"width: 100%;\"><em><b>Note:<\/b> Solar wind is a stream of charged particles released from the upper atmosphere of the Sun, called the corona.<\/em><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h5><b>What is the significance of this achievement?<\/b><\/h5>\n<p><span style=\"font-weight: 400;\">This is significant as touching the very stuff the Sun is made of will help scientists uncover critical information about the Sun and its influence on the solar system.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Moreover, <\/span><span style=\"font-weight: 400;\">exploring the corona close up can help scientists better understand solar outbursts that can interfere with life here on Earth.<\/span><\/p>\n<p><b>Source:<\/b> <span style=\"font-weight: 400;\">This post is based on the article<\/span><b> \u201c<\/b><b>NASA\u2019s Parker Solar Probe enters the Sun\u2019s atmosphere for the first time<\/b><b>\u201d <\/b><span style=\"font-weight: 400;\">published in<\/span><b>\u00a0Indian Express\u00a0<\/b>on<b> 15<\/b><sup><b>th<\/b><\/sup><b> Dec 2021.<\/b><\/p>\n","protected":false},"excerpt":{"rendered":"<p>What is the news?
