What Happened
The universe has been full of exciting developments this week. Researchers at the HUN-REN Wigner Research Center for Physics in Hungary have published a new paper that sheds light on the maximum weight of neutron stars. According to their findings, the weight of a neutron star can range between 2.2 and 2.3 solar masses.
Meanwhile, in a historic moment for space exploration, China's Shenzhou 21 astronauts returned to Earth on May 29, wrapping up a record-breaking 210-day mission to the Tiangong space station. The astronauts had launched on October 31 last year to relieve the Shenzhou 20 crew.
Why It Matters
The study on neutron stars is significant because it helps us better understand the behavior of these extreme objects. Neutron stars are incredibly dense, with the weight of two suns compacted into a sphere the size of a city. Each teaspoon of their material would weigh billions of tons.
The return of the Shenzhou 21 astronauts is also a milestone for China's space program, which has been rapidly expanding in recent years. The mission marked a new record for the longest duration of a Chinese crewed spaceflight.
What Experts Say
"The Chief Designer" Sergei Korolev was a pivotal figure in the early days of space exploration, overseeing the development of the R-7 rocket, Sputnik, and Vostok programs. — Apple TV series "Star City"
Key Numbers
- **2.2-2.3 solar masses: the maximum weight of a neutron star
- **210 days: the duration of the Shenzhou 21 mission
- **16x magnification: the power of binoculars needed to observe the Blue Moon hiding the red light of an ancient star
Background
The Soviet space program has a rich history, with many notable achievements, including being the first to launch a satellite, put a man in orbit, and conduct a spacewalk. Apple TV's new series "Star City" explores this history, offering a fascinating glimpse into the lives of Soviet cosmonauts and engineers.
What Comes Next
As we continue to explore the universe, we can expect more exciting discoveries and milestones. The Blue Moon on May 31 will offer a rare opportunity for stargazers to observe the red star Antares in the constellation Scorpius. Meanwhile, Apple TV's "Star City" series will surely spark interest in the Soviet space program and its many achievements.
