Astronomers have discovered a key ingredient for life at the edge of our Milky Way galaxy. A team from the University of Arizona detected the presence of phosphorus while studying molecular clouds on the outskirts of the galaxy using giant radio telescopes in the US and Spain. Phosphorus is one of the so-called NCHOPS elements that make up the critical ingredients for life on Earth – nitrogen, carbon, hydrogen, oxygen, phosphorus and sulphur. All of the others have already been found on the edge of the galaxy, so the discovery of phosphorus has direct implications for the search for Earth-like planets around distant stars. Their observations of the chemical 74,000 light-years from the centre of the Milky Way calls into question our fundamental understanding of the universe, the researchers said. “The phosphorus we detected is at the edge of the galaxy, where it shouldn’t be,” said Lilia Koelemay, a doctoral student at the University of Arizona who led the research. Theories that could explain its presence include supernova stars, which are typically not found on the edge of galaxies, and low mass stars generating excess neutrons that are then added onto silicon atoms to create phosphorus. “To make phosphorus, you need some kind of violent event,” said Lucy Ziurys, Regents Professor of chemistry and biochemistry and astronomy at Steward Observatory. “It is thought that phosphorus is created in supernova explosions, and for that, you need a star that has at least 20 times the mass of the Sun. In other words, if you’re going to have life, you better be near a supernova, if that’s indeed the only source where phosphorus is created.” The detection of phosphorus at the edge of the galaxy could motivate studies of distant exoplanets, the researchers hope, which have not been properly considered until now due to the assumed lack of the chemical. The research team now plans to examine other molecular clouds in the far reaches of the Milky Way to see if they contain phosphorus. Their discovery was described in a paper, titled ‘Phosphorus-bearing molecules PO and PN at the edge of the galaxy’, in the scientific journal Nature.

Millions of phones, TVs and radios across the US will receive an alert on Wednesday as part of a nationwide test for an emergency alert system. At 2.20pm ET, the Federal Emergency Management Agency (FEMA) will test the Emergency Alert System for TV and radio sets, and the Wireless Emergency Alerts for phones. “These test alerts are necessary to verify that the system is working properly so that, in a real case, citizens will know what to do, depending on the information that is issued,” said Nino Correa Filomeno, the commissioner of the Puerto Rico Emergency Management Bureau, who will coordinate with FEMA for the tests. “Amid this hurricane season, and any time an emergency occurs, it is necessary to have this system in place.” It is the seventh test for the system since FEMA set it up, however there are already conspiracy theories spreading online about its actual purpose. One false theory is that the signal is being sent to activate nanoparticles that have been introduced to people’s bodies, with one widely shared claim suggesting that it relates to the Covid-19 vaccine. Some users on X, formerly Twitter, advised people to shut off their phones in order to avoid receiving the alert. One user wrote: “Recommendations include not only disabling all alerts but also removing the sim card and shutting down your phone completely, possibly putting in a faraday bag if you have one.” Any smartphone that is switched on and within range of a cell tower will receive the emergency alert test message, which will be accompanied by a “unique tone” and vibration to make sure it is seen, heard or felt by as many people as possible, including those with disabilities. The radio and television portion of the test is being conducted with the participation of broadcasters, satellite providers and cable systems. “We want to ensure that the systems continue to be effective, that the public understands and uses these alerts and warnings about emergencies, particularly those on the national level, as we work to strengthen emergency readiness among our communities,” said Orlando Olivera, a coordinator at FEMA’s Caribbean office in Puerto Rico. “This is one step to be ready for emergencies. We are encouraging everyone, especially older adults to Take Control in 1, 2, 3: Assess your needs, Make a plan, and Engage your support network.” Read More Apple blames Instagram for overheating iPhones Japan startup unveils 15-foot robot suit for space exploration New discovery is ‘holy grail’ breakthrough in search for aliens, scientist say Elon Musk’s X ordered to pay over $1m in legal fees for laid off Twitter execs
