A new analysis of seismic data from NASA's Mars InSight mission has revealed a couple of surprises.
The first surprise: the top 300 meters of the subsurface beneath the landing site near the Martian equator contains little or no ice.
"We find that Mars' crust is weak and porous. The sediments are not well-cemented. And there's no ice or not much ice filling the pore spaces," said geo

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.

Atomic clock precision timing is essential for systems such as global navigation, satellite mapping, establishing the composition of exoplanets and the next generations of telecommunication. But atomic clocks are currently massive devices - weighing hundreds of kilograms - which need to be housed within precise, difficult-to-maintain conditions.

Lunar Zebro, a project of the Delft University of Technology in the Netherlands wants to build a robot and be the first Dutch and European rover to walk on the Moon. Their lunar rover does not only distinguish itself by its small size taking up the same area as an A4 sheet of paper, but also by its unique locomotion. Driven by C-shaped legs instead of wheels, the six-legged rover from where it takes its name in Dutch “zes-benige robot”, will be able to climb over much taller obstacles than its wheeled counterparts, making it ideal for
Gaia reveals the past and future of the Sun
Thursday, 11 August 2022 08:00
We all wish that we could sometimes see into the future. Now, thanks to the very latest data from ESA’s star mapping Gaia mission, astronomers can do just that for the Sun. By accurately identifying stars of similar mass and composition, they can see how our Sun is going to evolve in the future. And this work extends far beyond a little astrophysical clairvoyance.
