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
Just seven days later, a planetary radar observed the 1,001st bone of its kind, which was much larger
Scientists are making another small step towards cracking the mysteries of space weather
The oxygen found in the frozen world is linked to the sublimation of ground ice
They are powerful, they are the size of Australia and no one imagined them until a few years ago - what is the secret of the storms at the poles of the largest planet in the solar system?
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
NASA's Ingenuity Mars lander captured this takeoff as it hovered over the Martian surface on April 19, 2021
What would happen if the earth did not rotate on a north-south axis (like a shawarma skewer) but on some axis on the equator?
However, no danger is expected from this asteroid - on March 6, astronomers and astronomy enthusiasts watched the transit of the asteroid Apophis, which will return much closer to us in 2029
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
The autonomous landing of Persistence (Preservation) is supposed to be the most precise landing of a spacecraft on Mars to date
The Perseverance vehicle, built at NASA's Jet Propulsion Laboratory in Southern California, is loaded with scientific instruments, advanced landing computing capabilities and other new systems
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
Weather forecasting in space, which may affect the activity of satellites, the health of astronauts and the power grids about 24 hours before the occurrence, can be done using machine learning methods that rely on past events in combination with measurements in the atmosphere
Niv asks: Why does the compass point north if the dynamo that flows under the surface of the ground, under the entire earth, is the one that creates the magnetism?
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?
A new study by Weizmann Institute of Science scientists and their research partners in the USA indicates that at least some of the water on the moon may be trapped in much more accessible places - in pits and small depressions.
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)
Astronomers have discovered a rare element - phosphine - in the clouds of the planet Venus. On Earth, this gas is only produced in industry or it is emitted by bacteria living in an oxygen-limited environment
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.
