This week, researchers shared fascinating new findings on Uranus, the seventh planet from the sun, and the far side of the moon. Other worldsIllustrations depict how Uranus' magnetosphere, or protective bubble, was behaving before Voyager 2's arrival (left) and during the spacecraft's flyby (right). An unusual cosmic occurrence during the Voyager 2 spacecraft’s 1986 flyby might have skewed how scientists characterized the ice giant, new research suggests. In particular, the spacecraft’s observations of Uranus’ protective magnetosphere were wildly different from astronomers’ expectations. Fortunately, sending a dedicated mission to study Uranus in the future is a priority for NASA, according to a 2022 report.

☆ Voyager 2’s defining Uranus flyby may have been skewed by a rare cosmic event

Magnetospheres are the protective bubbles around planets like Earth that have magnetic cores and magnetic fields, and they are driven by the planet’s magnetic field. Voyager 2’s data showed that Uranus’ magnetosphere was home to unexpectedly powerful electron radiation belts. Voyager 2’s observations of Uranus’ magnetosphere defied the way astronomers understand how magnetic fields trap energetic particles and their radiation. The first panel (left) of this artist's concept depicts how Uranus' protective magnetosphere behaved prior to Voyager 2's flyby. Fortunately, sending a dedicated mission to study Uranus in the future has become a priority for NASA, according to a report released in 2022.

A vocational school student in China who wowed the public in June by finishing near the top in the preliminary round of a math contest was helped by her teacher in violation of the rules, the organizers said this week. An investigation found that the math teacher’s assistance broke a rule of “no discussion with others,” the Alibaba Global Mathematics Competition Organizing Committee said Sunday. For this, we express our sincere apologies,” the organizing committee said. The teacher, Wang Runqiu, also entered the contest and finished 125th in the preliminary round. Damo Academy, the contest organizer, didn’t respond to an email, and a call to the vocational school was unanswered on Tuesday.

“It could completely reshape our understanding of the solar system and of other planetary systems, and how we fit into that context. Brown and his colleague, planetary scientist Konstantin Batygin, reported having strong evidence of a hidden planet on the fringes of our solar system. “If you look at these bodies, their lifetimes are tiny compared to the age of the solar system,” Batygin said. “By now, we expected to have found many more of these extreme trans-Neptunian objects,” Sheppard said in an email. Finding a smaller planet would also spark excitement, Rice added, because every solar system planet is immensely useful for extrapolating information about the thousands of comparable exoplanets that researchers are uncovering across the galaxy.

Voyager 1 is now using a radio transmitter it hasn’t relied on since 1981 to stay in contact with its team on Earth while engineers work to understand what went wrong. NASA's Voyager 1 spacecraft is depicted in this artist's concept traveling through interstellar space, or the space between stars, which it entered in 2012. Voyager 1 has been using one of its two radio transmitters, called an X-band based on the frequency it utilizes, for decades. In the meantime, engineers sent a message to Voyager 1 on October 22 to check that the S-band transmitter was working and received confirmation on October 24. “The S-band signal is too weak to use long term,” Waggoner said.

The second moon that Earth has captured in its orbit this month is an asteroid called 2024 PT5. Mini-moons like this could be ideal targets for asteroid mining to send humans deeper into space. Space mining could be huge, since some asteroids are worth more than our entire global economy. Some startups are trying to figure out how to start mining space rocks, and do it in a cost-effective way. "Either if you are thinking about collecting mineral samples for research or starting a space mining venture, mini-moons are your best bet to get your business off the ground," he said.

CNN —Astronomers have observed a massive pair of jets releasing from a supermassive black hole 7.5 billion light-years from Earth. The megastructure spans 23 million light-years in length, making these black hole jets the largest ever seen, according to new research. Black hole jets can accelerate radiation and particles close to the speed of light, causing them to glow in wavelengths visible to radio telescopes.

CNN —Engineers at NASA have successfully fired up a set of thrusters Voyager 1 hasn’t used in decades to solve an issue that could keep the 47-year-old spacecraft from communicating with Earth from billions of miles away. Currently the farthest spacecraft from Earth, Voyager 1 is about 15 billion miles (24 billion kilometers) away. Earlier this year, engineers spotted an issue when the fuel tube inside one of Voyager’s thrusters became clogged. Engineers switched again to the trajectory correction thruster set in 2018 when the second set also appeared clogged. Once the spacecraft has exhausted this thruster set, Voyager 1’s remaining option is the other already clogged set of attitude propulsion thrusters.
