view of the Milky Way supermassive black hole Sagittarius A* iThe Event Horizon Telescope (EHT) collaboration, who produced the first ever image of our Milky Way black hole released in 2022, has captured a new view of the massive object at the centre of our Galaxy: how it looks in polarised light. This is the first time astronomers have been able to measure polarisation, a signature of magnetic fields, this close to the edge of Sagittarius A*. This image shows the polarised view of the Milky Way black hole. The lines overlaid on this image mark the orientation of polarisation, which is related to the magnetic field around the shadow of the black hole.https://cosmicave.org/wp-content/uploads/2025/11/image.pngimage2025-11-24T20:29:24+00:00monthlyhttps://cosmicave.org/2025/10/01/did-einstein-misunderstand-relativity/https://cosmicave.org/wp-content/uploads/2025/10/pnas.168fig01.jpegpnas.168fig01https://cosmicave.org/wp-content/uploads/2025/10/hubbles-original-diagram-from-hubble-1929-despite-the-typo-on-the-labelling-of-the-y_w640.jpgHubbles-original-diagram-from-Hubble-1929-Despite-the-typo-on-the-labelling-of-the-y_W640https://cosmicave.org/wp-content/uploads/2025/10/albert_einstein_sticks_his_tongue.jpgAlbert_Einstein_sticks_his_tongue2025-11-21T18:11:46+00:00monthlyhttps://cosmicave.org/course/astronomy-of-planets/8-jupiter-and-saturn/2025-11-04T03:01:57+00:00weekly0.6https://cosmicave.org/course/astronomy-of-planets/mod1/2025-11-04T02:38:27+00:00weekly0.6https://cosmicave.org/course/astronomy-of-planets/11-onward-and-upward-human-interests-the-search-for-extrasolar-planets-and-the-future-of-astronomy/pulsar-planets/2025-11-04T01:39:19+00:00weekly0.6https://cosmicave.org/course/astronomy-of-planets/11-onward-and-upward-human-interests-the-search-for-extrasolar-planets-and-the-future-of-astronomy/introduction-discovering-planets-beyond-our-solar-system/https://cosmicave.org/wp-content/uploads/2025/11/giordano_bruno.jpgGiordano_Brunohttps://cosmicave.org/wp-content/uploads/2025/11/epicurus_bust2.jpgEpicurus_bust22025-11-04T01:34:56+00:00weekly0.6https://cosmicave.org/course/astronomy-of-planets/10-asteroids-comets-and-the-origin-of-the-solar-system/2025-11-04T00:59:16+00:00weekly0.6https://cosmicave.org/course/astronomy-of-planets/10-asteroids-comets-and-the-origin-of-the-solar-system/supplementary-resources/2025-11-03T23:17:04+00:00weekly0.6https://cosmicave.org/course/astronomy-of-planets/10-asteroids-comets-and-the-origin-of-the-solar-system/glossary/2025-11-03T23:05:48+00:00weekly0.6https://cosmicave.org/course/astronomy-of-planets/10-asteroids-comets-and-the-origin-of-the-solar-system/conclusions-and-course-outlook/2025-11-03T23:02:14+00:00weekly0.6https://cosmicave.org/course/astronomy-of-planets/10-asteroids-comets-and-the-origin-of-the-solar-system/how-did-our-solar-system-form/2025-11-03T22:53:02+00:00weekly0.6https://cosmicave.org/course/astronomy-of-planets/10-asteroids-comets-and-the-origin-of-the-solar-system/meteors/2025-11-03T22:06:08+00:00weekly0.6https://cosmicave.org/course/astronomy-of-planets/10-asteroids-comets-and-the-origin-of-the-solar-system/comet-and-asteroid-space-missions/https://cosmicave.org/wp-content/uploads/2025/11/d_tag-2-frames.gifd_tag-2-frames2025-11-03T21:47:40+00:00weekly0.6https://cosmicave.org/course/astronomy-of-planets/10-asteroids-comets-and-the-origin-of-the-solar-system/comets/2025-11-02T23:14:38+00:00weekly0.6https://cosmicave.org/course/astronomy-of-planets/10-asteroids-comets-and-the-origin-of-the-solar-system/asteroids/2025-11-02T23:06:42+00:00weekly0.6https://cosmicave.org/course/astronomy-of-planets/10-asteroids-comets-and-the-origin-of-the-solar-system/a-first-look-at-solar-system-formation/2025-11-02T22:59:12+00:00weekly0.6https://cosmicave.org/course/astronomy-of-planets/10-asteroids-comets-and-the-origin-of-the-solar-system/introduction/2025-11-02T22:47:20+00:00weekly0.6https://cosmicave.org/course/astronomy-of-planets/9-uranus-neptune-and-the-kuiper-belt/2025-11-02T02:35:32+00:00weekly0.6https://cosmicave.org/course/astronomy-of-planets/9-uranus-neptune-and-the-kuiper-belt/supplementary-resources/2025-11-02T02:27:28+00:00weekly0.6https://cosmicave.org/course/astronomy-of-planets/9-uranus-neptune-and-the-kuiper-belt/glossary/2025-11-02T02:21:04+00:00weekly0.6https://cosmicave.org/course/astronomy-of-planets/9-uranus-neptune-and-the-kuiper-belt/conclusions-and-course-outlook/2025-11-02T02:13:15+00:00weekly0.6https://cosmicave.org/course/astronomy-of-planets/9-uranus-neptune-and-the-kuiper-belt/physical-characteristics-of-uranus-neptune-and-the-outer-icy-worlds/https://cosmicave.org/wp-content/uploads/2025/11/new_webb_image_captures_clearest_view_of_neptunee28099s_rings_in_decades.pngNew_Webb_Image_Captures_Clearest_View_of_Neptune%E2%80%99s_Rings_in_Decadeshttps://cosmicave.org/wp-content/uploads/2025/11/neptune_voyager2_color_calibrated.pngNeptune_Voyager2_color_calibratedhttps://cosmicave.org/wp-content/uploads/2025/11/uranus_voyager2_color_calibrated.pngUranus_Voyager2_color_calibratedhttps://cosmicave.org/wp-content/uploads/2025/11/annotated_uranian_rings.pngAnnotated_Uranian_ringshttps://cosmicave.org/wp-content/uploads/2025/11/stsci-01evssw4d16xy4dsv86hx9hn0h.pngSTScI-01EVSSW4D16XY4DSV86HX9HN0Hhttps://cosmicave.org/wp-content/uploads/2025/11/stsci-01evsswgy8jtj8mmbytc0qr68f-1.pngSTScI-01EVSSWGY8JTJ8MMBYTC0QR68Fhttps://cosmicave.org/wp-content/uploads/2025/11/stsci-01evsswgy8jtj8mmbytc0qr68f.pngSTScI-01EVSSWGY8JTJ8MMBYTC0QR68F2025-11-02T02:05:00+00:00weekly0.6https://cosmicave.org/course/astronomy-of-planets/9-uranus-neptune-and-the-kuiper-belt/discovery-of-the-outer-solar-system-uranus-nep

schematic image represents how light from a distant galaxy is distorted by the gravitational effects of a nearer foreground galaxy, which acts like a lens and makes the distant source appear distorted, but brighter, forming characteristic rings of light, known as Einstein rings. An analysis of the distortion has revealed that some of the distant star-forming galaxies are as bright as 40 trillion Suns, and have been magnified by the gravitational lens by up to 22
