All eyes on China-Brazil radio telescope mission to explore dark energy
Although scientists cannot fully explain it, dark energy is likely to compose around 68 per cent of the cosmos, according to Nasa. It is a repulsive, or antigravity, force that is causing the universe to expand. BINGO is short for 'baryon acoustic oscillations (BAO) from integrated neutral gas observations'. By measuring these sound waves, scientists hope to better understand the large-scale structure of the universe and discover more about dark energy. The remote location – nearly 2,000km (1,240 miles) from the capital Brasilia – was chosen for its low radio frequency interference, according to a 2019 article by the BINGO collaboration, the multinational project spearheaded by Brazil and China. The main structure of the radio telescope is expected to arrive in the hilly hinterland of Paraíba state on the Brazilian east coast in about two months and will be one of the largest of its kind in Latin America when completed in 2026. A major space science cooperation project between China and Brazil is entering its last pre-commission stages, with the departure of what will be an Olympic pool-sized telescope from the northern Chinese port of Tianjin on Monday. The first plans for BINGO, which aims to further the world's knowledge of dark energy, date back to 2011. The scientists are seeking to understand the possible connection to dark matter – a little-understood and, as of now, undetectable part of space that seems to have no interaction with light or the electromagnetic field, but makes up 27 per cent of the universe and holds galaxies together. The telescope's 40 metre (131 feet) long single radio dish will have two reflectors, 28 antennas – also called horns and what makes the instrument unique – as well as receivers and an analyser. BINGO's principal investigator, Carlos Alexandre Wuensche de Souza, senior scientist at the Astrophysics Division at INPE, the National Institute for Space Research in Brazil, was involved in the design and development of the horns. 'We have many, many horns looking at the same region in the sky, so we collect more data and can connect this data in an easier way. When you can cover a large region of space at the same time, you get more sensitivity,' he said. Researchers from China and Brazil are the main collaborators in the project, but scientists from Britain, France, Germany, South Africa and other countries have all been involved at some point in BINGO. 'The Chinese are very good to work with,' Wuensche said, pointing to the expertise in science and logistics that the project's partners from China bring to the table. If we can have good results, maybe we can tell some new things about dark energy Carlos Alexandre Wuensche de Souza, senior scientist Chinese state broadcaster CCTV reported that the main design and processing of the telescope were completed by Chinese experts. Wu Yang, senior engineer from the 54th Research Institute of the China Electronics Technology Group Corporation (CETC) and a core member of the BINGO project, told CCTV that the telescope's design was intended to simplify installation in Brazil. The Chinese researchers adopted a combination of panels and spatial truss structures to facilitate efficient installation and mass production, Wu said. CETC and scientists from multiple Chinese universities were involved in the telescope's surface and steel structure design and manufacturing process, with the project led by Elcio Abdalla, a professor at the University of São Paulo in Brazil. The telescope will also be able to detect movement of celestial bodies and allow scientists to study fast radio bursts – brief blasts of radio waves with massive energy output – and similar phenomena. 'We do not know what causes them, we do not know the model to explain why they are so bright, so intense and so short in time,' Wuensche said. Through the data collected with the telescope, he and his team may understand more of the physics behind them. Wuensche has high expectations of what the telescope could make possible. 'If it's well measured, if we can have good results, maybe we can tell some new things about dark energy,' he said. 'This would be a good contribution. This would be on the news.'

Music fan got on stage at concert to 'propose to girlfriend'...just hours later, he did something unspeakable
A scorned man is under arrest in Brazil following the murder of his former girlfriend, who refused to resume their relationship despite a public plea at a live concert. Adailton dos Santos attended musician Kelson Kizz's show as part of the Santo Antônio Festival in Santo Antônio, Paraibá on Wednesday and asked to make a marriage proposal to Vitória de Lima, 32, on the stage. Kelson Kizz obliged and stopped his show as dos Santos joined him in front of the band, video footage showed The singer appeared to be stunned when dos Santos changed his tune and whispered into his ear that what he really wanted to reconcile with de Lima. When Kelson Kizz how long they had been dating, dos Santos told him that they were separated for only a couple of days. 'Adailton mustered up the courage, it's today. He said she won't escape today,' Kelson Kizz said in the video. 'Santo Antônio, matchmaker, I hope you perform a miracle. Hello Vitória, where are you? I don't think she's coming.' They both waited around two minutes for de Lima, who failed to come to the stage, as a dejected dos Santos looked towards the crowd in shock. After the show, dos Santos returned to his home in town of Solânea, where de Lima also lived, and ambushed her when he saw her walking to her residence on Thursday at 4:36am, it is alleged. Authorities said Vitória de Lima (pictured) had broken up her relationship with Adailton dos Santos, her former boyfriend of two months, earlier during the week before she was ambushed by him and stabbed dead near her home Thursday Surveillance video showed De Lima attempted to run away from dos Santos before she fell with him to the ground and was stabbed, according to police. She was rushed to an area hospital, where she died from her injuries. A stunned Kelson Kizz took to his Instagram Story on Thursday in search of answers. 'This shocked me, I haven't slept since 7am, I haven't slept a wink, and somehow we end up feeling guilty, even though we know there was nothing we could have done,' he said. 'The guy went up, told the production team that it was a marriage proposal, and when he got to the front of the stage he said it was a reconciliation,' Kelson Kizz added. 'But he used the names of people from the victim's family, he knew the person's life in detail. We tried to smooth things over as best we could, but unfortunately he committed femicide.' Adailton dos Santos was seen on a surveillance video ambushing his former girlfriend, Vitôria de Lima, before he stabbed and killed her near her home in Santo Antônio, a city in the northeastern Brazilian state of Paraibá The Paraibá Military Police arrested dos Santos at the scene of the crime, which he returned to with a set of new clothes. He initially told officers that he was not involved and then confessed after the presented evidence linking him to de Lima's murder. Paraibá Military Police Diogenes Fernandes told Brazilian news outlet G1 that dos Santos and de Lima had dated for only two months before she called off the relationship earlier this week. 'In a cold manner, he goes to his residence, changes his shirt and returns to the scene of the crime in an attempt to simulate rescue for the victim,' Paraibá Military Police Diogenes Fernandes told Brazilian news outlet G1. 'He confessed to the crime, the murder weapon was seized and he was sent to the local public jail.'
