\n A massive star in a distant galaxy has baffled astronomers by disappearing without a trace.<\/p>\n

Scientists have been observing the star for decades as it was in the late stages of its lifespan meaning a huge supernova explosion could happen.<\/p>\n

It was observed shining brightly between 2001 and 2011 but 2019 data revealed its absence.<\/p>\n

Confused by how such a big star could mysteriously disappear, scientists looked back at data from 2016 and found the star was also missing back then.<\/p>\n

Somehow, it seems to have disappeared sometime after 2011.<\/p>\n

Now, scientists are wondering whether the star skipped the supernova stage, previously thought to be a necessary step in the end of a star\u2019s life.<\/p>\n

Instead, they think it could have just collapsed into a black hole.<\/p>\n

Astrophysicist Andrew Allan said: \u201cIf true, his would be the first direct detection of such a monster star ending its life in this manner.\u201d<\/p>\n

Scientists used to be able to detect the huge star in the Kinman Dwarf galaxy, 75 million light-years away in the Aquarius constellation.<\/p>\n

We don\u2019t currently have the technology<\/a> to observe individual stars at this distance but scientists used to be able to pick up light signatures for the luminous blue variable star in question.<\/p>\n

These stars are known supergiants or sometimes even hypergiants that are approaching the end of their lifespan.<\/p>\n

This makes them extremely unstable and bright, with constant changes in brightness expected.<\/p>\n

Early observations suggested the star was 2.5 to 3.5 million times as bright as the Sun.<\/p>\n

This is what makes the star suddenly disappearing without even a trace of a supernova very strange.<\/p>\n

Researchers have come up with two possible explanations for the mystery disappearance.<\/p>\n

The first is that the star has dimmed and is now shrouded in a huge cloud of dust made from its own eruptions.<\/p>\n

In the second scenario, the star went through its final death throws and collapsed into a black hole.<\/p>\n

We can\u2019t rule out that the massive star underwent an undetected supernova but it\u2019s highly unusual that it wouldn\u2019t leave an after glow for years to come.<\/p>\n

Astrophysicist Jose Groh said: \u201cWe may have detected one of the most massive stars of the local Universe going gently into the night.\u201d<\/p>\n

The research was led by PhD student Andrew Allan of Trinity College Dublin, Ireland.<\/p>\n

This study has been published in the Monthly Notices of the Royal Astronomical Society.\n <\/p><\/div>\n<\/p><\/div>\n<\/p><\/div>\n<\/div>\n
