Electromagnetic Radiation Interference:<\/strong> Starlink satellites emit unintended electromagnetic radiation (UEMR), which disrupts radio telescopes designed to detect radio waves from celestial objects.<\/p>\n<p><strong>2. Radio Astronomy Challenges:<\/strong> Radio telescopes are being &#8220;blinded&#8221; by the radio noise from Starlink satellites, similar to how bright light blinds human vision, saturating the radio telescopes&#8217; detectors.<\/p>\n<p><strong>3. Impact of Satellites in View:<\/strong> The presence of a satellite in a telescope&#8217;s field of view can obscure faint signals, making it difficult to observe weaker celestial objects.<\/p>\n<p><strong>4. Increased Brightness of New Satellites:<\/strong> Second-generation Starlink satellites emit UEMR at levels 32 times brighter than first-generation satellites, worsening the interference problem.<\/p>\n<p><strong>5. Growing Number of Satellites:<\/strong> With the increasing number of satellites (potentially up to 100,000 by 2030), the interference for radio astronomers is expected to intensify.<\/p>\n<p><strong>6. Need for Regulations:<\/strong> Experts call for regulations on satellite operators to minimize UEMR, similar to how there are rules for ground-based electronic sources like cellphone towers.<\/p>\n<p><strong>Read more:<\/strong> <a href=\"https:\/\/forumias.com\/blog\/space-internet-starlink-project\/\" target=\"_blank\" rel=\"noopener\">Starlink project<\/a><\/p>\n<p><strong>UPSC Syllabus: Science and technology\u00a0<\/strong><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Source-\u00a0This post on How Starlink Satellites Are &#8216;Blinding&#8217; Astronomers is based on the article \u201cHow Starlink satellites are \u2018blinding\u2019 astronomers\u201d published in Indian Express\u00a0on\u00a021st September 2024.
