Researchers are perplexed by the discovery of an exoplanet with a mass that greatly surpasses what would be predicted given its closeness to the parent star.

Within the immense cosmic expanse, a perplexing discovery has emerged—a planet that, by all technical expectations, should not exist.
A recent study published in Nature discusses the confirmation of an exoplanetary system based on data collected in 2020. The system, known as HD 110,067, possesses six planets whose orbits are in resonance with each other, or “in sync”, meaning which could offer profound insights into the formation and evolution of planetary systems throughout the cosmos. All the planets exhibit sizes between Earth and Neptune, also known as sub-Neptunes, and was conducted by an international team of researchers using data from NASA’s Transiting Exoplanet Survey Satellite (TESS) and the European Space Agency’s CHaracterising ExOPlanet Satellite (Cheops).

“This discovery is going to become a benchmark system to study how sub-Neptunes, the most common type of planets outside of the solar system, form, evolve, what are they made of, and if they possess the right conditions to support the existence of liquid water in their surfaces,” said Dr. Rafael Luque, who is a Postdoctoral Scholar in the Department of Astronomy and Astrophysics at the University of Chicago and lead author of the study.

The Earth’s magnetic field plays a big role in protecting people from hazardous radiation and geomagnetic activity that could affect satellite communication and the operation of power grids. And it moves.
Scientists have studied and tracked the motion of the magnetic poles for centuries. The historical movement of these poles indicates a change in the global geometry of the Earth’s magnetic field. It may even indicate the beginning of a field reversal—a “flip” between the north and south magnetic poles.
I’m a physicist who studies the interaction between the planets and space. While the north magnetic pole moving a little bit isn’t a big deal, a reversal could have a big impact on Earth’s climate and our modern technology. But these reversals don’t happen instantaneously. Instead, they occur over thousands of years.
A companion robot dog, designed to provide emotional support to astronauts, has been unveiled by a student from South Korea’s Hongik University.
The small-scale robot dog Laika is named after the first dog to orbit the Earth aboard Sputnik 2.
A video shows Laika running, walking, barking and sitting. It’s designed to replicate the movements and behavior of real dogs to provide an approachable design that enables emotional connection for astronauts during lengthy missions.
Number 4 Hamilton Place is a be-columned building in central London, home to the Royal Aeronautical Society and four floors of event space. In May, the early 20th-century Edwardian townhouse hosted a decidedly more modern meeting: Defense officials, contractors, and academics from around the world gathered to discuss the future of military air and space technology.
Things soon went awry. At that conference, Tucker Hamilton, chief of AI test and operations for the United States Air Force, seemed to describe a disturbing simulation in which an AI-enabled drone had been tasked with taking down missile sites. But when a human operator started interfering with that objective, he said, the drone killed its operator, and cut the communications system.
Scientists detected an extremely high-energy cosmic ray beaming from outer space — which confusingly came from nowhere in particular.

“Researchers can extract more knowledge from the same data, contributing to a deeper understanding of the cosmos”
Worlds orbiting a sun-like star 100 light-years from Earth could unlock secrets surrounding the formation of our solar system.
They are the most common type of planet observed in our Milky Way galaxy — two to three times the diameter of Earth but smaller than Neptune, and orbiting closer to their stars than our solar system’s innermost planet Mercury does to the sun.
