Astronomii care monitorizeaz\u0103 cometa interstelar\u0103 3I\/ATLAS afirm\u0103 c\u0103 aceasta a devenit mai luminoas\u0103 \u0219i a dezvoltat o str\u0103lucire verzuie, pe m\u0103sur\u0103 ce se apropie de P\u0103m\u00e2nt, mai t\u00e2rziu \u00een aceast\u0103 lun\u0103, potrivit LiveScience<\/a><\/span>.<\/p>\n

Telescopul Gemini surprinde cometa \u00eentr-o faz\u0103 de activitate intens\u0103<\/h2>\n

Noi imagini realizate recent cu telescopul Gemini North din Hawaii arat\u0103 cometa 3I\/ATLAS \u00eentr-una dintre cele mai active etape observate p\u00e2n\u0103 acum.<\/p>\n

Dup\u0103 apropierea de Soare la finalul lunii octombrie, \u00eenc\u0103lzirea intens\u0103 a determinat sublimarea ghe\u021bii de pe comet\u0103, eliber\u00e2nd gaze \u0219i praf \u00een spa\u021biu.<\/p>\n

Acest proces a dus la formarea unei come luminoase \u00een jurul nucleului \u0219i a unei cozi extinse \u0219i str\u0103lucitoare.<\/p>\n

Folosind mai multe filtre optice, astronomii au detectat o nuan\u021b\u0103 verzuie discret\u0103 \u00een coma cometei, absent\u0103 \u00een observa\u021biile anterioare.<\/p>\n

Cercet\u0103torii atribuie aceast\u0103 culoare prezen\u021bei carbonului diatomic, un gaz frecvent \u00eent\u00e2lnit la cometele activate, care emite lumin\u0103 verde sub influen\u021ba radia\u021biei solare.<\/p>\n

Schimb\u0103rile de culoare ofer\u0103 indicii despre compozi\u021bia cometei<\/h2>\n

Oamenii de \u0219tiin\u021b\u0103 noteaz\u0103 c\u0103 3I\/ATLAS<\/a><\/span> avea un aspect vizibil mai ro\u0219iatic la primele observa\u021bii din luna august, \u00eenainte de \u00eent\u00e2lnirea cu Soarele.<\/p>\n

Aceast\u0103 schimbare sugereaz\u0103 c\u0103, pe m\u0103sur\u0103 ce se \u00eenc\u0103lze\u0219te, cometa elibereaz\u0103 noi molecule, oferind indicii despre structura sa chimic\u0103.<\/p>\n

Emisii verzi similare au fost observate \u0219i la alte comete cunoscute din Sistemul Solar, sus\u021bin\u00e2nd ideea c\u0103 3I\/ATLAS<\/a><\/span> se comport\u0103 ca o comet\u0103 natural\u0103, \u00een ciuda originii sale interstelare.<\/p>\n

Pe m\u0103sur\u0103 ce se apropie de punctul de maxim\u0103 apropiere de P\u0103m\u00e2nt, pe 19 decembrie, la circa 270 de milioane de kilometri, astronomii spun c\u0103 sunt posibile noi episoade de activitate.<\/p>\n

Unele comete reac\u021bioneaz\u0103 \u00eent\u00e2rziat la \u00eenc\u0103lzirea solar\u0103, declan\u0219\u00e2nd eliber\u0103ri bru\u0219te de gaze sau praf chiar \u0219i dup\u0103 ce se \u00eendep\u0103rteaz\u0103 de Soare.<\/p>\n

Un vizitator rar din afara Sistemului Solar<\/h2>\n

Cometa 3I\/ATLAS<\/a><\/span> este doar al treilea obiect interstelar confirmat observat vreodat\u0103, dup\u0103 Oumuamua \u0219i 2I\/Borisov.<\/p>\n

Descoperit\u0103 \u00een luna iunie, \u00een timp ce traversa Sistemul Solar cu o vitez\u0103 extrem de mare, este considerat\u0103 probabil cel mai mare \u0219i, posibil, cel mai vechi obiect interstelar observat p\u00e2n\u0103 \u00een prezent.<\/p>\n","protected":false},"excerpt":{"rendered":"
