इस्रो has successfully launched the satellite XPoSat which is world’s second ‘X-ray Polarimetry जागा Observatory’. This will carry out research in जागा-based polarisation measurements of X-ray emission from various cosmic sources. Earlier, नासा had sent ‘Imaging X-ray Polarimetry Explorer (IXPE)’ into जागा in 2021 for the same objectives. X-ray Polarimetry जागा Observatories measure the amount and direction of polarization of incoming X-rays emanating from cosmic bodies and अत्यंत परिस्थितीत निसर्गाच्या नियमांचा अभ्यास करण्यासाठी एक अद्वितीय साधन म्हणून काम करते.
भारतीय जागा Research Organisation (इस्रो) has successfully launched XPoSat, a ‘X-ray Polarimetry Observatory’. It is designed to carry out research in जागा-based polarisation and spectroscopic measurements of X-ray emission from cosmic sources.
यात POLIX (क्ष-किरणांमध्ये पोलारिमीटर इन्स्ट्रुमेंट) आणि XSPECT (एक्स-रे स्पेक्ट्रोस्कोपी आणि टाइमिंग) असे दोन पेलोड असतात. POLIX थॉमसन स्कॅटरिंगद्वारे सुमारे 8 संभाव्य वैश्विक स्त्रोतांमधून निघणाऱ्या ऊर्जा बँड 30-50keV मध्ये क्ष-किरणांचे ध्रुवीकरण मोजेल, तर XSPECT पेलोड ऊर्जा बँड 0.8 मध्ये वैश्विक क्ष-किरण स्त्रोतांचा दीर्घकालीन वर्णपट आणि तात्पुरता अभ्यास करेल. -15के.
नासाचा Imaging X-ray Polarimetry Explorer (IXPE) launched into जागा on 9 December 2021 was the first X-ray Polarimetry जागा Observatory. Since its launch, it has contributed to several groundbreaking research through studying polarization of X-rays from many different types of celestial objects such as the remnants of supernova explosions, powerful particle streams spit out by feeding काळा राहीलइ
X-ray Polarimetry जागा Observatories measure the amount and direction of polarization of incoming X-rays emanating from cosmic bodies.
Since polarised light carries unique details about the source and medium it has passed through, X-ray Polarimetry जागा Observatories like IXPE and XPoSat serve as a unique tool to study the laws of nature in extreme conditions.
