The University of Western Australia’s ‘TeraNet’, a network of optical ground stations specializing in high-speed space communications, has successfully received laser signals from a German satellite in low Earth orbit. This breakthrough paves the way for a 1,000-fold increase in communication bandwidth between space and Earth.

TeraNet’s laser communication test with OSIRISv1 marks a step towards replacing outdated radio systems with high-speed lasers for space communications in Western Australia. With funding from Australian governments, the network aims to support diverse missions, enhancing data transfer capabilities across multiple sectors.

LeoLabs will provide space tracking and monitoring, and collision-avoidance services to the U.K. Space Command’s Project Tyche.

“This new planet supports the theory that high eccentricity migration should account for some fraction of hot Jupiters,” said Dr. Sarah Millholland.

How do exoplanets evolve throughout their lifetimes, specifically those known as “hot Jupiters”, which have been found to orbit extremely close to their parent stars? This is what a recent study published in Nature hopes to address as an international team of researchers investigated the highly eccentric orbit of TIC 241,249,530 b, which is a Jupiter-sized exoplanet located approximately 1,100 light-years from Earth. This study holds the potential to help astronomers better understand the formation of exoplanets like hot Jupiters and how their orbits evolve over time.

Now, TIC 241,249,530 b could help astronomers piece together the evolution of hot Jupiters given the exoplanet’s highly eccentric orbit, meaning it travels very close to its parent star at certain points followed by swinging back out to well beyond the parent star, completing one orbit in 167 days. Astronomers hypothesize this could mean that hot Jupiters initially begin as cold Jupiters in highly eccentric orbits only to slowly become more circular and closer to its parent star over time.

Various forms of hopping robots have crept into development for use in different space exploration missions. We’ve reported on their use on asteroids and even our own moon. But a study funded by NASA’s Institute for Advanced Concepts (NIAC) in 2018 planned a mission to a type of world where hopping may not be as noticeable an advantage—Europa.

After pondering its existence for decades, scientists have confirmed the first moon cave. Here’s how the structures could contribute to long-term lunar exploration.

“Astronomers have been searching for exoplanets that are likely precursors to hot Jupiters, or that are intermediate products of the migration process, for more than two decades, so I was very surprised — and excited — to find one,” team leader Arvind Gupta, a NOIRLab postdoctoral researcher, said in a statement. “It’s exactly what I was hoping to find.”

The scientists first used the NN-EXPLORE Exoplanet and Stellar Speckle Imager (NESSI) to remove “twinkling” patterns caused by Earth’s atmosphere, as well as reduce noise coming from other sources of light that could pollute the signal from the star TIC 241,249,530 as its planet transits its face.

Next, they measured the velocity of the exoplanet around the star using the NEID spectrograph to determine the star’s shift in light.

AI will enable drone wingmen to make autonomous decisions without centralized command.

According to Airbus, FCAS will be centered around a core Next Generation Weapon System (NGWS). In this “system of systems,” piloted New Generation Fighters will work together with Unmanned Remote Carriers – all connected to other systems in space, in the air, on the ground, at sea and in cyberspace via a data cloud called the “Combat Cloud.”

“One of the long-term aims of the research is to make better tailored foods for astronauts, as well as other people who are in isolated environments, to increase their nutritional intake closer to 100%,” said Dr. Julia Low.

Does food smell and taste different to astronauts in space and what steps can be taken to mitigate this in the future? This is what a recent study published in the International Journal of Food Science & Technology as an international team of researchers investigated how food aromas could be altered to amplify food taste. This study holds the potential to help researchers improve diets for isolated individuals, specifically in space or nursing home residents.

For the study, the researchers analyzed food odor perception of vanilla, almond, and lemon among 54 participants between 18 to 39 years old in a neutral setting and a virtual reality (VR) simulation of the International Space Station (ISS) with a key trait being they had no history of vertigo or motion sickness. The participants were asked to rate the potency of the aromas in both settings to compare any differences between the two environments.

At the very smallest scales, our intuitive view of reality no longer applies. It’s almost as if physics is fundamentally indecisive, a truth that gets harder to ignore as we zoom in on the particles that pixelate our Univerrse.

In order to better understand it, physicists had to devise an entirely new framework to place it in, one based on probability over certainty. This is quantum theory, and it describes all sorts of phenomena, from entanglement to superposition.

Yet in spite of a century of experiments showing just how useful quantum theory is at explaining what we see, it’s hard to shake our ‘classical’ view of the Universe’s building blocks as reliable fixtures in time and space. Even Einstein was forced to ask his fellow physicist, “Do you really believe the Moon is not there when you are not looking at it?”
