The Macao Science Satellite 1 network, China's leading space-based geomagnetic monitoring system, has achieved remarkable feats and attracted scientists from around the world, according to a top member of the program. Zhang Keke, director of the Macao Institute of Space Technology and Application, said in an exclusive interview on Tuesday that research into geomagnetic fields is one of the

Recent research, as detailed in a study published in ACS Central Science, presents a novel perspective on the origins of life's essential components, particularly amino acids. The study posits that carbamic acid, a simple amino acid, may have formed in the vicinity of stars or planets within interstellar ices. This groundbreaking hypothesis provides a new avenue for understanding how the buildin

Hanwha Systems, a major South Korean technology conglomerate, has recently entered into a distribution partnership agreement with Eutelsat OneWeb, part of the renowned Eutelsat Group and the world's first GEO-LEO satellite operator. This strategic collaboration aims to offer high-speed, low latency connectivity services across South Korea, signaling a significant advancement in the nation's comm

Three astronomers from the Netherlands have proven that gas that was previously heated near a supermassive black hole and flowed to the outskirts of the galaxy and cooled down, is moving back towards the black hole. While there had been indirect evidence for this theory, this is the first time that the cooled gas moving toward the black hole has actually been observed. The researchers made their

The discovery of a planet that is far too massive for its sun is calling into question what was previously understood about the formation of planets and their solar systems, according to Penn State researchers. In a paper published online in the journal Science, researchers report the discovery of a planet more than 13 times as massive as Earth orbiting the "ultracool" star LHS 3154, which

A new study develops a theory of how magnetic switchbacks are formed around the sun. This quantitative model can be used to predict magnetic field variations and potentially explain the heating and acceleration of the solar wind.

The lead author Dr. Gabor Toth worked with Dr. Bart van der Holst at the University of Michigan Department of Climate and Space Sciences and Engineering and Dr. Marco Velli at UCLA to publish the study, "Theory of Magnetic Switchbacks Fully Supported by Parker Solar Probe Observations," in The Astrophysical Journal.

Magnetic switchbacks are reversals of the radial magnetic field in the solar wind, which emanates from the surface of the sun. First seen sporadically in the seventies, magnetic switchbacks have recently been identified as a typical component of solar wind fluctuations in the inner heliosphere by the Parker Solar Probe.

Observations from the Parker Solar Probe revealed that these magnetic switchbacks consist of spherically polarized Alfvén waves, but until now, scientists had no concept of how these switchbacks were being formed.

New ideas in space exploration come from all corners, and, by and large, the community welcomes anybody interested in the field. Having just read "A City on Mars," it seems that even people who disagree with the idea that the age of space settlement is imminent will be accepted into the fold by enthusiasts. Now, a new entrant has joined—Daniel Akinwumi is a Nigerian graduate student at the University of Strathclyde who recently posted his master's thesis to ResearchGate detailing the design of the "intergalactic hub," or I-HUB.

The introductory section of the thesis lays out many of the challenges familiar to those interested in space habitats. These include the importance of robots, a completely closed-loop recycling system, and novel radiation shielding. Mr. Akinwumi also provides a thorough literature search and mentions several other design concepts similar to the I-HUB.

One crucial design choice is how to get the system into space.
