Researchers have developed an Artificial Intelligence (AI)-powered tool that has been trained to “look” at colour images and identify galaxy clusters quickly.

The “Deep-CEE” – Deep Learning for Galaxy Cluster Extraction and Evaluation – model is based on neural networks, which are designed to mimic the way a human brain learns to recognise objects by activating specific neurons when visualising distinctive patterns and colours.


Matthew Chan, a PhD student at Lancaster University in Britain trained the AI by repeatedly showing it examples of known, labelled objects in images until the algorithm is able to learn to associate objects on its own. Then the researchers ran a pilot study to test the algorithm’s ability to identify and classify galaxy clusters in images that contain many other astronomical objects.

“Data mining techniques such as deep learning will help us to analyse the enormous outputs of modern telescopes” said John Stott from Lancaster University. “We expect our method to find thousands of clusters never seen before by science,” Stott said.

Galaxy clusters represent the most extreme environments that galaxies can live in and studying them can help us better understand dark matter and dark energy. New state-of-the-art telescopes have enabled astronomers to observe wider and deeper than ever before, such as studying the large-scale structure of the universe and mapping its vast undiscovered content.

By automating the discovery process, scientists can quickly scan sets of images, and return precise predictions with minimal human interaction.

This will be essential for analysing data in future. The upcoming Large Synoptic Survey telescope (LSST) sky survey (due to come online in 2021) will image the skies of the entire southern hemisphere, generating an estimated 15 TB of data every night. “We have successfully applied Deep-CEE to the Sloan Digital Sky Survey,” said Chan.

“Ultimately, we will run our model on revolutionary surveys such as the LSST that will probe wider and deeper into regions of the Universe never before explored,” Chan added. The study was presented at the Royal Astronomical Society’s National Astronomy meeting at Lancaster University. (IANS)

Rihanna was summoned from her seat to accept the honour, with the Prime Minister.

Singer Rihanna was honoured by Prime Minister Mia Mottley at an event which marked Barbados's new status as a republic, which was attended by Prince Charles. Addressing the pop star by her real name, the PM said: "Robyn Rihanna Fenty tomorrow morning shall have conferred upon her the order of national hero of Barbados."

Rihanna was then summoned from her seat to accept the honor, with the Prime Minister managing to rouse a laugh from the singer when she referenced her 2012 hit 'Diamonds', reports femalefirst.co.uk. She added: "On behalf of a grateful nation, but an even prouder people, we therefore present to you, the designee, for the national hero of Barbados." "And to accept on behalf of a grateful nation - you can come my dear - ambassador Robyn Rihanna Fenty, may you continue to shine like a diamond and bring honor to your nation." Rihanna, who was born in the St Michael parish of Barbados, found fame in 2005 after being spotted by a record producer and has since gone on to become one of the most successful female artists of all time with sales of over 250 million and recently reached billionaire status through her Fenty beauty brand.

The Prime Minister continued in her speech: "Commanding the imagination of the world through the pursuit of excellence, her creativity, her discipline, and above all else, her extraordinary commitment to the land of her birth. "Having satisfied that, Ambassador Robyn Rihanna Fenty has given service to Barbados which has been exemplified by visionary and pioneering leadership, extraordinary achievement and the attaining of the highest excellence to the Government of Barbados." It comes after a historic move for Barbados, which has become a republic after almost 400 years and welcomes its first president, Sandra Mason, after removing Queen Elizabeth as head of state.

Typically, Glaucoma occurs in people with over the age of 60 however it can occur at any age.

By IANSlife

Have you ever faced eye redness? Or have witnessed blurry or foggy vision? Or experiencing halos around lights? Or nausea and vomiting are very common for you. You may well be suffering from Glaucoma which needs immediate attention.

Glaucoma is the second most common causes of blindness worldwide, according to a report by World Health Organisation (WHO). Typically, it occurs in people with over the age of 60 however it can occur at any age. It is also estimated that globally 79.6 million people are affected with glaucoma, half of them being Asian population. While in India, around 11.9 million people suffer vision impairment and out of which 1.2 million cases are due to Glaucoma. It is a growing concern for the population in India. Even after these high numbers, the enormous majority remains undiagnosed, and untreated. More than 90 percent of cases of Glaucoma remain undiagnosed.
