Evolution of Hot Jupiters: From Cold Giants to Star-Hugging Worlds

Posted by in categories: computing, space

“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.

Quantum light unlocks nature’s tiny secrets

Posted by in categories: engineering, quantum physics

Researchers at the University of Michigan have found a way to examine tiny structures, such as bacteria and genes, with reduced damage compared to traditional light sources.

The new technique involves spectroscopy, which is the study of how matter absorbs and emits light and other forms of radiation, and it takes advantage of quantum mechanics to study the structure and dynamics of molecules in ways that are not possible using conventional light sources.

“This research examined a quantum light spectroscopy technique called entangled two-photon absorption (ETPA) that takes advantage of entanglement to reveal the structures of molecules and how ETPA acts at ultrafast speeds to determine properties that cannot be seen with classical spectroscopy,” said study senior author Theodore Goodson, U-M professor of chemistry and of macromolecular science and engineering.

Space radiation can damage satellites − my team discovered that a next-generation material could self-heal when exposed to cosmic rays

Posted by in categories: materials, satellites

The space environment is harsh and full of extreme radiation. Scientists designing spacecraft and satellites need materials that can withstand these conditions.

In a paper published in January 2024, my team of materials researchers demonstrated that a next-generation semiconductor material called metal-halide perovskite can actually recover and heal itself from radiation damage.

A hopping robot could explore Europa using locally harvested water

Posted by in categories: robotics/AI, space

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.

Huawei’s long-awaited Windows challenger will likely come to PCs this year — HarmonyOS Next makes the transition from phones to desktops and laptops

Posted by in categories: computing, mobile phones

HarmonyOS Next, on the other hand, is an Android-free variant of HarmonyOS. The new operating system doesn’t use AOSP libraries, can’t run.apk files, and is a significant step towards complete independence from US-based software for the vendor. HarmonyOS Next is not currently shipping with Huawei products but is available as a developer sandbox to develop and test apps for native HarmonyOS use. HarmonyOS Next hasn’t yet arrived on PC, but recent leaks suggest it soon will, paving the way for a new Chinese homegrown desktop OS.

Images of HarmonyOS Next for PC suggest an operating system taking design cues from MacOS. The system has a familiar status bar and dock bar combo on the top and bottom. The fullscreen/minimize/close buttons live on the right-hand side of programs, mirroring MacOS’s traffic light system.

Huawei’s recent strategy for HarmonyOS has publicly been phones-first. With HarmonyOS being open-source, much like Android, widespread adoption across the Chinese market and beyond outside of Huawei phones is possible and a big goal for Huawei. HarmonyOS already makes up 16% of the Chinese phone market, which is expected to grow in the coming years.

Hip-Hop History in Space: Missy Elliott’s Song Beamed to Venus by NASA

Posted by in categories: media & arts, space travel

“Both space exploration and Missy Elliott’s art have been about pushing boundaries,” said Brittany Brown. “Missy has a track record of infusing space-centric storytelling and futuristic visuals in her music videos, so the opportunity to collaborate on something out of this world is truly fitting.”

The planet Venus just received a gift from NASA, but this time it’s not in the form of a spacecraft or lander, but instead in the form of a hip hop song transmitted by the agency’s Deep Space Network, “The Rain (Supa Dupa Fly)”, which was originally released in 1997 by the hip hop artist, Missy Elliott. Not only is Venus the favorite planet of Missy Elliott, but this also marks only the second time a song has been transmitted into the unknown, with the first being “Across the Universe” from The Beatles in 2008.

The song was sent to Venus on July 12, 2024, at 10:05 am PDT by the Deep Space Station 13 radio dish antenna located in Barstow, California, with the command being sent from NASA’s Jet Propulsion Laboratory in Pasadena, California. The song took approximately 14 minutes to reach Venus traveling at the speed of light.

Youth with conduct disorder show widespread differences in brain structure

Posted by in categories: biotech/medical, neuroscience

A neuroimaging study of young people who exhibit a persistent pattern of disruptive, aggressive, and antisocial behavior, known as conduct disorder, has revealed extensive changes in brain structure.

NIH-funded study of conduct disorder identifies new brain areas associated with the disorder, offering future directions for research efforts and clinical practice.
