The Hubble telescope has imaged V838 Mon and its light echo several times since the star's outburst. Each time Hubble observes the event, different thin sections of the dust are seen as the pulse of illumination continues to expand away from the star at the speed of light, producing a constantly changing appearance. During the outburst event whose light reached Earth in 2002, the normally faint star suddenly brightened, becoming 600,000 times more luminous than our Sun.", "blurhash": "UB8g5BI;0y$fxHkCIojY9@xF-CJAI.n$$+X9", "focalPoint": [ 0, 0 ], "width": 2400, "height": 3000 } ], "tag": [ { "type": "Hashtag", "href": "https://mastodon.social/tags/astronomy", "name": "#astronomy" }, { "type": "Hashtag", "href": "https://mastodon.social/tags/physics", "name": "#physics" } ], "replies": { "id": "https://mastodon.social/users/coreyspowell/statuses/113506011869057345/replies", "type": "Collection", "first": { "type": "CollectionPage", "next": "https://mastodon.social/users/coreyspowell/statuses/113506011869057345/replies?only_other_accounts=true&page=true", "partOf": "https://mastodon.social/users/coreyspowell/statuses/113506011869057345/replies", "items": [] } }, "likes": { "id": "https://mastodon.social/users/coreyspowell/statuses/113506011869057345/likes", "type": "Collection", "totalItems": 16 }, "shares": { "id": "https://mastodon.social/users/coreyspowell/statuses/113506011869057345/shares", "type": "Collection", "totalItems": 19 } }
