New research has improved the accuracy of the parameters governing the expansion of the Universe. More accurate parameters will help astronomers determine how the Universe grew to its current state, and how it will evolve in the future.
It is well established that the Universe is expanding. But with no landmarks in space, it is difficult to accurately measure how fast it is expanding. So, Ringing protons give insight into early universe

In the middle of the last century, physicists found that protons can resonate, much like a ringing bell. Advances over the last three decades have led to 3D pictures of the proton and significant insight into its structure in its ground state. But little is known about the 3D structure of the resonating proton.
Now, an experiment to explore the 3D structures of resonances of protons and ne Pentagon awards contracts for next 'swarm' of tiny missile defense satellites

The Pentagon announced Monday it has awarded $1.5 billion to contractors Northrop Grumman and Lockheed Martin for a "swarm" of 72 tiny prototype satellites meant to detect incoming enemy missiles.
The Space Development Agency said each company will build and operate 36 of the satellites, with approximately $816 million going to Lockheed Martin and $733 million to Northrop Grumman for the p Listening for "sounds" from the far corners of space

Scientists spectacularly confirmed the existence of gravitational waves several years ago, but now they are searching the cosmos for new and different types of these waves that result from different objects in deep space.

A study of 14 astronauts suggests that while space travel depletes red blood cells and bone, the body can eventually replenish them back on Earth with the help of fat stored in the bone marrow. The study, published in Nature Communications, has important implications for health in space and on Earth.

India hopes to be first nation to land on south pole of moon later this week

Days after Russia failed to put a lander on the moon, the Indian Space Research Organization will try to become the first country to land on the moon's south pole on Wednesday.
On Monday, the space agency said its Chandrayaan-3 lander, the Vikram, had been mapping potential landing spots as it orbits the moon. Scientists believe frozen water may be hidden on the south pole, along with o Russia's space agency head vows to continue Moon race

The chief of the Russian space agency Roscosmos on Monday advocated for Russia to stay in the lunar race, a day after announcing its mission had crashed.
"In no case should the lunar program be interrupted, that would be the worst decision," Yuri Borisov said in an interview on television.

Maglevs are one of those technologies that still look like magic, even years after they were initially rolled out. While they have long been a workhorse of the transportation systems of some major cities, they don't often impact the day-to-day lives of people who don't use them to commute. But, they might be invaluable in another setting—lunar exploration. There's an ongoing debate about the best way to shuttle stuff around on the moon's surface, and a team from JPL and a company called SRI International think they have a solution—deploy a maglev track on the moon.
The project, known as the Flexible Levitation on a Track (FLOAT) system, is simple in concept. It is based on a concept developed at SRI that showcases the ability to float small robots over a platform and precisely control their movements using a form of magnetic levitation. Scale-wise, as seen in the video below, the technology so far is still small.
Want to find UFOs? That's a job for machine learning

In 2017, humanity got its first glimpse of an interstellar object (ISO), known as 1I/"Oumuamua, which buzzed our planet on its way out of the solar system. Speculation abound as to what this object could be because, based on the limited data collected, it was clear that it was like nothing astronomers had ever seen. A controversial suggestion was that it might have been an extraterrestrial probe (or a piece of a derelict spacecraft) passing through our system.
Public fascination with the possibility of "alien visitors" was also bolstered in 2021 with the release of the UFO Report by the ODNI.
This move effectively made the study of unidentified aerial phenomena (UAP) a scientific pursuit rather than a clandestine affair overseen by government agencies. With one eye on the skies and the other on orbital objects, scientists are proposing how recent advances in computing, AI, and instrumentation can be used to assist in the detection of possible "visitors.
Scientists introduce the design and application prospect of China's Tiangong space station

China's manned space project was approved in 1992 with a three-step strategic plan, and building a space station is the final goal of this plan.
In September 2010, China's manned space station project was officially established. On April 29, 2021, the Tianhe core module was successfully launched into orbit by the carrier rocket Long March-5B at the Wenchang Spacecraft Launch Site in Hainan.
As planned, by 11 launches and on-orbit missions, China has completed the assembly and started the official operation of the space station. With the completion and operation of the Tiangong space station, China will become the third country able to build and operate space stations independently after the Soviet Union and the United States.
In a research paper published in Space: Science & Technology, specialists from Institute of Spacecraft System Engineering, China Academy of Space Technology introduce the design of the Tiangong space station, summarize the technical characteristics of the Tiangong space station, and discuss the future application and development of the space station.
Space travel depletes red blood cells and bone, but bone marrow fat may come to the rescue

A study of 14 astronauts suggests that while space travel depletes red blood cells and bone, the body can eventually replenish them back on Earth with the help of fat stored in the bone marrow. The study, published in Nature Communications, has important implications for health in space and on Earth.
"We found that astronauts had significantly less fat in their bone marrow about a month after returning to Earth," said senior study author Dr. Guy Trudel, a rehabilitation physician and researcher at The Ottawa Hospital and professor at the University of Ottawa. "We think the body is using this fat to help replace red blood cells and rebuild bone that has been lost during space travel."
This study builds on Dr.

Webb captures detailed beauty of Ring Nebula
Monday, 21 August 2023 13:00 Write a comment
The NASA/ESA/CSA James Webb Space Telescope has observed the well-known Ring Nebula with unprecedented detail. Formed by a star throwing off its outer layers as it runs out of fuel, the Ring Nebula is an archetypal planetary nebula. The object is also known as M57 and NGC 6720, and is relatively close to Earth at roughly 2,500 light-years away.
