Researchers find mathematical trick to combining planetary surface data.
Researchers have discovered a method for making high-resolution maps of planetary surfaces like the moon’s by combining available imagery and topography data.
Mapping the complex and diverse surface of a world like the moon in detailed resolution is challenging because laser altimeters, which measure changes in altitudes, operate at much lower resolution than cameras. And although photographs offer a sense of surface features, it’s difficult to translate images into specific heights and depths.
According to a research paper published in Nature, astronomers detected a “really weird” object 4,000 lightyears distant from Earth. Every other minute, the object vanishes from view and produces a massive burst of radio waves three times an hour. Tyrone O’Doherty, a Curtin University student, first noticed the enigmatic object while scanning the sky in […].

Tourism officials in Florida’s Space Coast are expecting a massive influx of tourists for the upcoming Artemis 1 moon mission, the first launch for NASA’s Space Launch System rocket and Orion spacecra.
The stellar smash produced a short gamma-ray burst that could provide important context for understanding similar blasts.
In trying to understand the nature of the cosmos, some theorists propose that the universe expands and contracts in endless cycles.
Because this behavior is hypothesized to be perpetual, the universe should have no beginning and no end—only eternal cycles of growing and shrinking that extend forever into the future, and forever into the past.
It’s an appealing concept in part because it removes the need for a state called a singularity that corresponds to “beginning of time” in other models.
Analysing pendulum videos, the artificial intelligence tool identified variables not present in current mathematics.
An artificial intelligence tool has examined physical systems and not surprisingly, found new ways of describing what it found.
How do we make sense of the universe? There’s no manual. There’s no prescription.
At its most basic, physics helps us understand the relationships between “observable” variables – these are things we can measure. Velocity, energy, mass, position, angles, temperature, charge. Some variables like acceleration can be reduced to more fundamental variables. These are all variables in physics which shape our understanding of the world.
A half-mile-long tunnel under Menlo Park, California, just became colder than most of the universe.
Using a superconducting X-ray laser, researchers at SLAC achieved a temperature 2 degrees Celsius above absolute zero.
