First ever black hole image released

Astronomers have taken the first ever image of a black hole, which is located in a distant galaxy.

It measures 40 billion km across - three million times the size of the Earth - and has been described by scientists as "a monster".

The black hole is 500 million trillion km away and was photographed by a network of eight telescopes across the world.

It was captured by the Event Horizon Telescope (EHT), a network of eight linked telescopes, the black hole was found in a galaxy called M87 and what we see is larger than the size of our entire Solar System.

Feeling blue? Scientists find navy is the most relaxing colour - with turquoise and pastel pink also helping to beat stress

Humans often associate specific colours with particular events, emotions and even moods and now, experts found navy blue is the most relaxing colour.

They say surrounding yourself with blue clothes, objects and accessories could help you lead a more relaxed life, according to Daily Mail.

Calmness is most inspired by dark blues, turquoises and pinks while the colours of luxury include purple, orange, and white.

Research from the University of Sussex and fine paper company G.F Smith asked 26,596 people from more than 100 countries to name their favourite colour.

UK scientists discover world's tallest tropical tree

Scientists in the UK and Malaysia say they have discovered the world's tallest tropical tree measuring more than 100m (328ft) high.
The lofty yellow meranti was spotted in a Borneo rainforest by a team from the University of Nottingham last year, according to BBC.
Researchers from the University of Oxford then carried out 3D scans and drone flights to confirm the record.
The tree, found in the Danum Valley Conservation Area in Sabah, has been named Menara, which is Malay for tower.

Rivers raged on Mars late into its history

Long ago on Mars, water carved deep riverbeds into the planet's surface -- but we still don't know what kind of weather fed them. Scientists aren't sure, because their understanding of the Martian climate billions of years ago remains incomplete.

A new study by University of Chicago scientists catalogued these rivers to conclude that significant river runoff persisted on Mars later into its history than previously thought, the runoff was intense -- rivers on Mars were wider than those on Earth today -- and occurred at hundreds of locations on the red planet, according to Science Daily.

Building blocks of LIFE arrived on Mars after asteroids crashed into the red planet and flourished thanks to its thick atmosphere

Asteroids that crashed into Mars may have brought with them the building blocks needed for life. 

A new study has found 'key ingredients for life' were transported to the red planet millions of years ago when the space rocks landed on it. 

Mars may have had an atmosphere made of hydrogen at the time and if this was the case, asteroids would likely have brought nitrogen to the planet - an essential element for many biological molecules, according to Daily Mail.

It involved creating various mixtures in flasks designed to imitate early asteroid impacts on Mars.
