The moon’s glow meets a multicolored aurora in a new astronaut image from space.
International Space Station (ISS) and NASA astronaut Matthew Dominick, a veteran photographer of the Expedition 71 crew, captured the moon and auroras from his perch 250 miles (400 kilometers) above Earth.
A new study provides evidence that Mars contains a large ocean deep beneath its surface.
The finding is based on data collected by the InSight Lander, a robotic explorer operated by the American space agency NASA. InSight, which landed in 2018, was designed to capture data from within the planet’s interior. The lander ended its operations on Mars in late 2022.
For the current study, researchers used seismic data collected by InSight. The team examined the data to study Martian quake activity. Seismic activity on Mars happens in the form of “marsquakes.” NASA says InSight had recorded more than 1,300 marsquakes.
🎵🎶…Mars ain’t the kind of place to raise your kids…🎵🎶 Even then, since Mars has 38% of Earth’s gravity, it can only retain an atmosphere of about 0.38 bar.
These are some of the most compelling ideas on how to terraform Mars into a habitable, Earth-like world for future explorers.
A new theory suggests time travel might be possible without creating paradoxes.
TL;DR:
A physics student from the University of Queensland, Germain Tobar, has developed a groundbreaking theory that could make time travel possible without creating paradoxes. Tobar’s calculations suggest that space-time can adjust itself to avoid inconsistencies, meaning that even if a time traveler were to change the past, the universe would correct itself to prevent any disruptions to the timeline. This theory offers a new perspective on time loops and free will, aligning with Einstein’s predictions. While the math is sound, actual time travel remains a distant possibility.
Following NASA ’s DART mission, which successfully tested asteroid deflection techniques by colliding with the moonlet Dimorphos, extensive research has revealed insights into the geological features and evolutionary history of the Didymos asteroid system.
Studies have characterized the surface and interior of these celestial bodies, examined their formation processes, and assessed their response to impacts. These findings not only provide a clearer understanding of binary asteroid systems but also enhance planetary defense strategies.

WASHINGTON — U.S. Space Command’s top general voiced support for the U.S. Army’s efforts to expand its space expertise, pushing back against criticism that such initiatives encroach on Space Force territory. Gen. Stephen Whiting, commander of U.S.
Future space missions could use quantum technology to track water on Earth, explore the composition of moons and other planets, or probe mysterious cosmic phenomena.
Right off the bat, one of the biggest improvements is the weight of the 4,680 shell itself – down to 49g from the 70g weight of a gen 1 cell. Tesla has essentially optimized the shell, making it thinner, and reducing its internal complexity. They do this by welding the tabless electrode to the cell cap.
That weight reduction is significant – at the battery pack level, the Cybertruck has 1,344 cells – which means that it reduces 28.2kg or 62.1lb of the overall pack weight. But rather than leaving that space empty, Tesla has instead filled that weight with more battery material. Calculated, that’s about a 10% increase in overall pack energy density.

“By measuring sound travel time differences both forward and backward, we can accurately measure wind in three dimensions,” said Dr. Robert White.
The planet Mars has several similarities with Earth, including extinct volcanoes, dry lake beds, and active dust storms, the last of which is governed by the Red Planet’s prevailing winds. However, given the average surface pressure of Mars is 0.6 percent of Earth’s due to Mars’ paper-thin atmosphere, which means the wind speeds are far smaller than on Earth. But can we accurately measure this wind speed and how will it contribute to future missions to the Red Planet?
This is what a recent study published in the Journal of the Acoustical Society of America hopes to address as a team of researchers investigated using sound to measure wind speeds on Mars, which holds the potential to help scientists better understand the various processes that comprise the Red Planet and how these processes could influence future missions, as well.

“Certainly,” says Christof Koch, Ph.D., a neuroscientist and prominent figure in the field of consciousness studies. “Any complex system, whether evolved on Earth or elsewhere, could be conscious.” What that consciousness might look like is another matter entirely. Could aliens exhibit empathy, self-awareness, love, hate, or fear?
To answer these questions, consider panpsychism, an ancient cosmic theory that suggests consciousness could be a ubiquitous feature of the universe, akin to gravity or charge. This idea, dating back to ancient Greek philosophers like Thales and Plato, has seen a resurgence in the 21st century as mainstream scientific approaches struggle to fully explain consciousness.
