Here we probe the microscopic dynamic mechanism for plasmon-induced methane dissociation over a tetrahedral Ag 20 nanoparticle with molecular orbital insights using time-dependent density functional ...

Apophis is a near-Earth asteroid that has captured global attention due to its close approach predicted for the year 2029. Measuring approximately 340 meters in diameter, this space rock has ...

That asteroid is name Apophis, and it initially posed a sizable threat to Earth when it was first discovered in 2004 before scientists eventually calculated that its trajectory was harmless.

The Ramses mission just got more complex, and more interesting. Once feared as a threat to Earth, the asteroid Apophis is now considered to pose a rare exploration opportunity — if space ...

We report on the discovery and characterization of the transiting planet K2-39b (EPIC 206247743b). With an orbital period of 4.6 days, it is the shortest-period planet orbiting a subgiant star known ...

While the planet masses range from 0.26 to 0.90 M-J, the radii are all approximately a Jupiter radii, resulting in a wide range of bulk densities. The orbital period of the planets ranges from 2.7 ...

Uranus, the seventh planet in the solar system, located between Saturn and Neptune, has long been a mystery. But by analyzing observations made by NASA’s Hubble Space Telescope over a 20-year ...

Politecnico di Milano Department of Aerospace Science and Technology’s Francesco Topputo and Fabio Ferrari said: "Being part of the Apophis mission is a tremendous honour. We are developing ...

This period was marked by the expansion of frontier defense systems amid significant geopolitical transformations. Contrary to the traditional view of such walls as solely defensive structures ...
