One evening while watching the Oort Cloud scene, scientists noticed something strange projected onto the planetarium’s dome.“Why is there a spiral there?” said the museum’s Jackie Faherty.

The inner section of the Oort Cloud, made of billions of comets, resembled a bar with two waving arms, similar to the shape of our Milky Way galaxy.Scientists had long thought the Oort Cloud was shaped like a sphere or flattened shell, warped by the push and pull of other planets and the Milky Way itself. The planetarium show hinted that a more complex shape could lie inside.The museum contacted the researcher who provided the Oort Cloud data for the show, who was also surprised to see the spiral.

“It’s kind of a freak accident that it actually happened,” said David Nesvorny with the Southwest Research Institute.Realizing they’d stumbled on something new, the researchers

earlier this year in The Astrophysical Journal.

The spiral is “a striking shift in our understanding of the outer solar system,” planetary scientist Andre Izidoro with Rice University, who was not involved with the study, said in an email.People in provinces as far away as Guantánamo, Artemisa, Santiago de Cuba, and Santa Clara reported experiencing blackouts with just flickers of light.

Earlier, the Electric Union, the state agency that regulates the sector, said in its daily report that peak-hour demand would be around 3,250 megawatts and the deficit would reach around 1,380 megawatts, meaning 42% of the national energy system would be shut down. This figure is not the highest in recent memory.at the end of last year, leaving the island in the dark amid a serious economic crisis.

Cuba’s power grid has been plagued by frequent outages, with more than half of the country experiencing power cuts during peak hours. The outages are primarily caused by. In many parts of the island, electricity is crucial for cooking and water pumping.
