One of the researchers responsible for the discovery tells how an asteroid similar to the one that caused the incident in Tungaska in Siberia in 1908, hit a city in Jordan northeast of the Dead Sea. The city was abandoned afterwards, and the echoes of the explosion hit other cities in the vicinity, including Jericho

The south pole of the moon is one of the coldest regions in our solar system. No previous mission to the surface of the moon has explored it - until now scientists have explored the area using remote sensing instruments, in 2023 NASA will launch a robotic vehicle that will explore the area on the ground

The researchers based their work on previous observational data that showed the asteroid is primarily a mixture of three components: metal, low-iron pyroxene and carbonaceous chondrite. A laboratory experiment led the researchers to the conclusion that the density of the asteroid is low. A NASA spacecraft is expected to reach it by 2026

A catalyst that breaks down a chlorine compound (perchlorate) in water could help clean the soil on the planet Mars during manned habitation on Mars. It is a substance that accumulates in plants and makes them toxic if it is not removed from the water with which they will water the plants that will be served by humans who will fly there

The spacecraft will conduct its survey in infrared. Telescopes on Earth have found most of the nearby objects cataloged so far, but the remaining ones are very difficult to find in visible light

Are events in the distant past, such as the extinction of the dinosaurs, about ten percent closer in time to us? And how does it relate to solar flares? This is according to ongoing research by a group headed by Prof. Yitzhak Orion from Ben Gurion University. In an interview with the Hidan site, Prof. Orion also explains the role of the neutrino particle in the phenomenon

No one will doubt that China aims to win the new space race. Not only is it the only country to have landed on the moon in over 40 years, but it is also the first to make a soft landing on the far side of the moon, plant a flag on the lunar soil and even bring lunar soil samples to Earth. It is now also landing a robotic all-terrain vehicle on Mars

At the time of conjunction, both planets will be seen in the west direction, just after sunset over the southwestern horizon close to the setting sun. The next closest cluster - in March 2080 * And how does this relate to the way we discover planets outside the solar system?

The Sophia airborne observatory has detected water molecules (H2O) in Calveus Crater, one of the largest craters visible from Earth, located in the southern hemisphere of the Moon. Previous observations of the lunar surface detected some type of hydrogen compound, but failed to distinguish water from its close chemical relative, hydroxyl (OH)

Harvard University scientists say the Sun may once have had a binary companion with a similar mass. If the theory is confirmed, the presence of an ancient companion star increases the likelihood that the Oort cloud formed as it is observed and the ninth planet was trapped rather than formed within the solar system.
