Depuis plusieurs ann\u00e9es, des radiot\u00e9lescopes australiens d\u00e9tectent un signal provenant du centre de la Voie Lact\u00e9e, dont l\u2019origine est encore inconnue.<\/strong><\/p>\n

Depuis quelques ann\u00e9es, les radiot\u00e9lescopes australiens ont d\u00e9tect\u00e9 \u00e0 plusieurs reprises un signal dans l\u2019espace<\/a>, qui proviendrait du centre de la Voie Lact\u00e9e.<\/p>\n

Un signal inconnu dans l\u2019espace<\/h2>\n

Entre avril 2019 et ao\u00fbt 2020, ce\u00a0signal<\/a>\u00a0myst\u00e9rieux a \u00e9t\u00e9 enregistr\u00e9 13 fois par le r\u00e9seau australien. R\u00e9cemment et pour la premi\u00e8re fois, il a \u00e9t\u00e9 d\u00e9tect\u00e9 en f\u00e9vrier et en avril 2021 par un radiot\u00e9lescope situ\u00e9 en Afrique du Sud. Baptis\u00e9 ASKAP J173608.2-321635 par les astronomes de l\u2019universit\u00e9 de Sydney, ce signal est tr\u00e8s variable puisqu\u2019il peut parfois durer plusieurs semaines, puis dispara\u00eetre soudainement.<\/p>\n

Ce signal n\u2019existe nulle part dans les archives des astronomes, qui n\u2019avaient jamais capt\u00e9 ce signal auparavant. Ainsi, ce ph\u00e9nom\u00e8ne r\u00e9cent est toujours un grand myst\u00e8re inexpliqu\u00e9.<\/p>\n

L\u2019origine du signal toujours inexpliqu\u00e9e<\/h2>\n

Ce signal interpelle les scientifiques puisqu\u2019il n\u2019est accompagn\u00e9 d\u2019aucun autre signal ni d\u2019aucun rayon X. Pour cette raison, les astronomes affirment qu\u2019il ne provient pas d\u2019une \u00e9toile \u00e9ruptive. Une enqu\u00eate a \u00e9t\u00e9 ouverte pour d\u00e9couvrir ce qui est \u00e0 l\u2019origine de ce signal.<\/p>\n

Selon les hypoth\u00e8ses soulev\u00e9es par les scientifiques, il pourrait \u00eatre li\u00e9 \u00e0 un \u00e9v\u00e9nement inhabituel dans l\u2019espace<\/a>, puisqu\u2019un fait similaire s\u2019\u00e9tait d\u00e9j\u00e0 produit lors de l\u2019explosion d\u2019une \u00e9toile, qui avait aval\u00e9 un trou noir.<\/p>\n

Jusqu\u2019\u00e0 pr\u00e9sent, les astronomes pensent qu\u2019il s\u2019agirait d\u2019un signal provenant du centre de la Voie Lact\u00e9e. Trois autres signaux similaires avaient d\u00e9j\u00e0 \u00e9t\u00e9 enregistr\u00e9s dans les ann\u00e9es 2000, sans que l\u2019on puisse en expliquer l\u2019origine.<\/p>\n
