I 'm not a broadcaster. I don't work in TV and I don't have access to any surveys or insights that can explain executive-level or coverage choices made by networks. I 'm a guy who sits on his couch and watches racing. That's my weekend side hustle, and I take it very seriously.   Astronomers have discovered a new ring system around a newly discovered dwarf planet, named Quaoar. Discovered in 2002, Quaoar is around half the size of Pluto and orbits the Sun [...]

Structure appears to be so far out, the Roche limit may need revising A ring system has been spotted around dwarf planet Quaoar at a distance astronomers didn't believe was possible, defying astronomical theories on how these structures form.… Quaoar lies in the Kuiper belt beyond Neptune. The icy rock is 1,121 kilometers (697 miles) wide, about half the diameter of Pluto. Quaoar is a distant object with interesting properties, including signs it may harbor ice-spewing [...]

New telescope data has revealed that a dwarf planet in the outer reaches of the solar system has a dense ring around it, leaving scientists and astronomers confused as to why. Scientists at the European Space Agency announced Wednesday that data and observations of the planet Quaoar which was collected between 2018 and 2021 —from ground-based telescopes, and the space-based telescope Cheops — led them to the discovery. The ESA disclosed that Quaoar crossed in front [...]

The dwarf planet Quaoar, which sits beyond Neptune in our solar system, appears to have a ring of debris around it that is much further out than was thought possible. We have observed a ring that shouldn’t be there,” says Bruno Morgado at the Federal University of Rio de Janeiro in Brazil. That is because until now, every ring or orbiting moon observed by astronomers has obeyed a limit put forward by astronomer Édouard Roche in 1848. Below the Roche limit, the [...]

This icy rock beyond Neptune has a ring, and it's raising some questions. While an object the size of Spain drifts through the distant Solar System, astronomers watch it block faraway starlight to gather information. Recently, they found something exciting: this primordial chunk has a ring. This is a show-stopping feature of Saturn and other planets, but much smaller bodies have them too. A decade ago, this same team made the first-ever detection of a ring around an asteroid. The [...]

WASHINGTON (Reuters) - The small distant world called Quaoar, named after a god of creation in Native American mythology, is producing some surprises for astronomers as it orbits beyond Pluto in the frigid outer reaches of our solar system. Researchers said on Wednesday they have detected a ring encircling Quaoar akin to the one around the planet Saturn. But the one around Quaoar defies the current understanding of where such rings can form - located much further away from it than current [...]

Violent acts and other crimes by Arab and Jewish youths have reached shocking levels in Israel in recent years, triggering calls for the training and hiring of hundreds or even thousands more police officers. Yet a study just published in Scientific Reports under the title “Childhood individual and family modifiable risk factors for criminal conviction: A 7-year cohort study from Brazil” by psychiatrists at the Federal University of São Paulo Medical [...]

Washington: Daniel Martins-de-Souza and colleagues used MRI to compare brain structure in 81 study participants recovering from a mild COVID-19 infection and 81 healthy individuals. The authors found that the former group exhibited reduced cortical thickness, which was correlated with cognitive impairments and symptoms such as anxiety and depression. The authors analyzed brain samples from 26 people who had died of COVID-19, finding that samples from five of these individuals exhibited [...]

In the beginning of the pandemic, stay-at-home orders may have left some feeling as though time had stalled. To better understand how individuals’ perceptions of time changed throughout the pandemic, Brazilian researchers conducted an online survey. They found different phases of the pandemic corresponded with feelings of “time expansion” and “time pressure.” As the months living with COVID-19 turned into years living with COVID-19, to many it may have [...]
