Rogue Planets Floating in Space Appear to Be Forming Their Own Moons
Free-floating, planetary-mass objects that are just drifting carefree through the galaxy, untethered and starless, appear to be able to generate their own systems of moons, like a planetary system on a miniature scale.
An analysis of new JWST observations on a number of rogue planets – each weighing between five and 10 Jupiters – has revealed the presence of disks with a significant proportion of crystalline silicate, just like those surrounding some baby stars right before their planets start to form.
“These studies show that objects with masses comparable to those of giant planets have the potential to form their own miniature planetary systems,” says observational astronomer Aleks Scholz of the University of St Andrews in the UK.
Magnetically induced convection enhances water electrolysis in microgravity
Electrochemical devices producing oxygen in space face limited buoyancy, hindering gas bubble removal and increasing reaction overpotentials. Now, it has been shown that commercial magnets can enhance the reaction efficiency and induce phase separation in microgravity. The optimized magnetoelectrochemical architectures developed here may guide the designs of future life-support systems.
Mysterious Object Hurtling Toward Us From Beyond Solar System Appears to Be Emitting Its Own Light, Scientists Find
The object, dubbed 3I/ATLAS, has caught the attention of Harvard astronomer Avi Loeb, who has a long track record of making controversial predictions about previous interstellar objects being relics from an extraterrestrial civilization.
While there’s been a growing consensus among astronomers that the latest object is a comet, Loeb has continued to entertain the idea that it may have been sent to us by an intelligent species from outside of the solar system — and he’s far from backing down.
In a blog post over the weekend, Loeb pointed to observations by NASA’s Hubble Space Telescope, which showed a “glow of light, likely from a coma, ahead of the motion of 3I/ATLAS towards the Sun.”
Voyager: An Inside Look At NASA’s Longest-Running Mission With Someone There From The Start
We bring you an exclusive behind-the-scenes look at this iconic mission with Dr Linda Spilker, from her first job out of college to serving as the current Voyager Project Scientist.
The Last Time NASA’s Voyager “Looked Back” At Our Solar System, This Is What It Saw
Before it met the 30,000–50,000 kelvin wall at the edge of our Solar System, Voyager 1 took its final images.
Apollo Moon sample opened after 50 years contains evidence of extraterrestrial landslide
More than 50 years after the last manned moon mission, the Apollo program is still making groundbreaking discoveries.
Lunar rock collected by Apollo 17 is revealing more about the Light Mantle, a distinctive bright streak across the moon’s surface. It’s believed to be the remains of an ancient landslide that happened in the distant past, but the exact cause is unknown.
Asteroid strikes, debris from a nearby mountain and seismic activity are all possibilities, but orbital photographs can only reveal so much. Scientists are now studying a rock core from Apollo 17 that was recently unsealed for the first time in 50 years, allowing new insights into the geology of the area.
Chinese scientists create nuclear battery with 3x better efficiency
Scientists unveil nuclear battery with 50-year lifespan and triple efficiency.
Researchers in China have developed a novel nuclear battery that can withstand at least half a century of radiation and deliver three times the energy efficiency of conventional designs.
The team set out to improve battery performance in extreme environments, led by Haisheng San, PhD, a professor at Xiamen University, and Xin Li, PhD, a researcher at the China Institute of Atomic Energy.
According to the scientists, conventional power systems, especially those used in extreme conditions such as space or deep-sea infrastructure, struggle with long-term reliability.
