Researchers from Western have shown that a fireball that originated at the edge of the Solar System was likely made of rock, not ice, challenging long-held beliefs about how the Solar System was formed.
Just at the edge of our Solar System and halfway to the nearest stars is a collection of icy objects sailing through space, known as the Oort Cloud. Passing stars sometimes nudge these icy Outer space talks are a welcome addition to the US-Africa Leaders Summit

President Joe Biden is hosting the Second US-Africa Leaders Summit in mid-December 2022.
The focus will be on eight areas: economic engagement; peace, security and good governance; democracy and human rights; regional and global health security (including recovery from COVID-19 and pandemic preparedness); food security; climate change; diaspora ties; and education and youth leadership. China launches two space experiment satellites
Wednesday, 14 December 2022 10:11
China on Monday launched a Long March-4C rocket, placing a pair of satellites in space.
The rocket blasted off at 4:22 pm (Beijing Time) from the Jiuquan Satellite Launch Center in northwest China and sent the satellites Shiyan-20A and Shiyan-20B into preset orbit.
Shiyan means "experiment" in Chinese. The two Shiyan-20 satellites will be used for in-orbit verification of new technol US conducts successful hypersonic missile test: Air Force

The US Air Force announced Monday it successfully tested a hypersonic missile, a cutting edge strategic weapon that is also being developed by China and Russia.
The AGM-183A Air-launched Rapid Response Weapon (ARRW) was launched from a B-52H bomber on Friday off California's coast and "reached hypersonic speeds greater than five times the speed of sound, completed its flight path and detonat Asteroid Ryugu samples continue to shed light on solar system history
Wednesday, 14 December 2022 10:11
Nearly two years after Japanese mission Hayabusa2 returned to Earth, samples from asteroid Ryugu continue to reveal valuable information about the history of the early solar system. A study by scientists from the Institut de Physique du Globe de Paris, Universite Paris Cite and CNRS1, as part of an international consortium, reveals the isotopic composition of zinc and copper of asteroid Ryugu.
