Our solar system is expected to face a dramatic transformation because of an impending galactic event that will see a neighbouring galaxy collide with the Milky Way, potentially throwing planets into interplanetary space.
Life on Earth, however, will likely come to an end billions of years before that as the Sun, our life-giving star, becomes too hot for any living organism to survive.
Humans still have plenty of time, though, as these apocalyptic events are projected to unfold over the next five billion years.
Pauline Barmby, chairwoman of the department of physics and astronomy at the Western University in Ontario, Canada, has described what could be left of our solar system once the Andromeda galaxy eventually merges with it.
“A collision between the Milky Way and Andromeda, if it happens, won’t occur all at once,” she told The National.
“Most models of the galaxies’ orbits have them coming in for a close approach some time between five and eight billion years from now, separating for a few billion years, and then finally coalescing.”
The detailed fate of the solar system is not known with certainty, however, because the current orbits of the galaxies are difficult to measure precisely, according to Ms Barmby.
She said the part of the solar system that would most likely be affected by the Milky Way-Andromeda collision would be the Oort Cloud – a distant region of icy objects and comets surrounding the outer edges of the solar system.
“While nearby stars aren’t likely to themselves collide due to the galaxy collision, their orbits will change, and some will likely come near enough that they gravitationally perturb the Oort Cloud’s comets and eject some of them from the solar system,” said Ms Barmby.
Galaxy mergers can take place over hundreds of millions of years as gravitational forces slowly draw them together, distorting their shape and causing star formation, with the full merger process completing over an extended period.
The Sun holds the key
However, it is the dying Sun that could do the most damage to Earth and its neighbouring planets years before the merger.
It is expected to expand into a red giant mass – when it runs out of hydrogen fuel and swells to many times its original size – destroying Mercury and Venus in the process.
“Mars and the other outer planets are expected to survive, although their orbits will expand,” said Ms Barmby.
“Earth’s fate is unclear, because it’s difficult to predict exactly how much mass the Sun will lose in its red giant phase. If Earth is not destroyed, it certainly won’t be habitable.”
The remaining planets might not last much longer either, as they could be thrown out of the solar system entirely after the galaxy collision, when stars passing near the Sun cause gravitational influences between them.
"Over the very long term, 10 to 100 billion years from now, gravitational perturbations from stars passing near the Sun will cause gravitational interactions between the remaining planets - eventually they too will likely be ejected from the solar system," said Ms Barmby.
Dr Nidhal Guessoum, professor of physics and astronomy at the American University of Sharjah, echoed Ms Barmby’s thoughts and said that life on Earth “will have disappeared” well before the merger.
“As the Sun’s power continues to slowly increase it would make life on Earth impossible in about half a billion years from now,” he said.
While it may be a while until our galaxy merges with another, collisions in the universe are quite common, according to Dr Guessoum.
“We have a number of well-known and well-imaged cases of merged, distorted galaxies," she said. “Such mergers, which are due to gravitational pulls between galaxies, often lead to new stars being formed - and most likely new planets around them - by compression of galactic gas and dust.”
Some of the most well-documented galaxy mergers in the universe include the Antennae Galaxies, labelled as NGC 4038/NGC 4039), where two spiral galaxies are merging, creating tidal tails of stars and intense star formation known as a ‘starburst’.
Another example is the Cartwheel Galaxy, formed when a smaller galaxy passes through a larger one, producing a ring structure and triggering waves of star formation.

Mercer, the investment consulting arm of US services company Marsh & McLennan, expects its wealth division to at least double its assets under management (AUM) in the Middle East as wealth in the region continues to grow despite economic headwinds, a company official said.
Mercer Wealth, which globally has $160 billion in AUM, plans to boost its AUM in the region to $2-$3bn in the next 2-3 years from the present $1bn, said Yasir AbuShaban, a Dubai-based principal with Mercer Wealth.
“Within the next two to three years, we are looking at reaching $2 to $3 billion as a conservative estimate and we do see an opportunity to do so,” said Mr AbuShaban.
Mercer does not directly make investments, but allocates clients’ money they have discretion to, to professional asset managers. They also provide advice to clients.
“We have buying power. We can negotiate on their (client’s) behalf with asset managers to provide them lower fees than they otherwise would have to get on their own,” he added.
Mercer Wealth’s clients include sovereign wealth funds, family offices, and insurance companies among others.
From its office in Dubai, Mercer also looks after Africa, India and Turkey, where they also see opportunity for growth.
Wealth creation in Middle East and Africa (MEA) grew 8.5 per cent to $8.1 trillion last year from $7.5tn in 2015, higher than last year’s global average of 6 per cent and the second-highest growth in a region after Asia-Pacific which grew 9.9 per cent, according to consultancy Boston Consulting Group (BCG). In the region, where wealth grew just 1.9 per cent in 2015 compared with 2014, a pickup in oil prices has helped in wealth generation.
BCG is forecasting MEA wealth will rise to $12tn by 2021, growing at an annual average of 8 per cent.
Drivers of wealth generation in the region will be split evenly between new wealth creation and growth of performance of existing assets, according to BCG.
Another general trend in the region is clients’ looking for a comprehensive approach to investing, according to Mr AbuShaban.
“Institutional investors or some of the families are seeing a slowdown in the available capital they have to invest and in that sense they are looking at optimizing the way they manage their portfolios and making sure they are not investing haphazardly and different parts of their investment are working together,” said Mr AbuShaban.
Some clients also have a higher appetite for risk, given the low interest-rate environment that does not provide enough yield for some institutional investors. These clients are keen to invest in illiquid assets, such as private equity and infrastructure.
“What we have seen is a desire for higher returns in what has been a low-return environment specifically in various fixed income or bonds,” he said.
“In this environment, we have seen a de facto increase in the risk that clients are taking in things like illiquid investments, private equity investments, infrastructure and private debt, those kind of investments were higher illiquidity results in incrementally higher returns.”
The Abu Dhabi Investment Authority, one of the largest sovereign wealth funds, said in its 2016 report that has gradually increased its exposure in direct private equity and private credit transactions, mainly in Asian markets and especially in China and India. The authority’s private equity department focused on structured equities owing to “their defensive characteristics.”

Farage on Muslim Brotherhood
Nigel Farage told Reform's annual conference that the party will proscribe the Muslim Brotherhood if he becomes Prime Minister.
"We will stop dangerous organisations with links to terrorism operating in our country," he said. "Quite why we've been so gutless about this – both Labour and Conservative – I don't know.
“All across the Middle East, countries have banned and proscribed the Muslim Brotherhood as a dangerous organisation. We will do the very same.”
It is 10 years since a ground-breaking report into the Muslim Brotherhood by Sir John Jenkins.
Among the former diplomat's findings was an assessment that “the use of extreme violence in the pursuit of the perfect Islamic society” has “never been institutionally disowned” by the movement.
The prime minister at the time, David Cameron, who commissioned the report, said membership or association with the Muslim Brotherhood was a "possible indicator of extremism" but it would not be banned.
