Researchers simulated the harsh ionizing radiation conditions of Mars to see how long freeze-dried bacteria and fungi could survive
Scientists from Durham University's Institute for Computational Cosmology have used the most detailed supercomputer simulations to date to uncover an alternative explanation for the origin of the Moon, in which a giant impact put a Moon-like body in orbit around Earth.
This was announced by the SpaceIL association. ImageSat is an old Israeli company that provides high-resolution satellite photographs of sites on Earth, and now one of the devices on Lavinia will map the moon in collaboration with researchers at Ben Gurion University
Israeli scientists participated in the DART asteroid interception project
DART, which is the world's first attempt to change the speed and trajectory of an asteroid in space, is trying a method to deflect asteroids that could be useful if such a need arises in the future to protect Earth. 
A large impact crater under the North Atlantic Ocean reveals - the deadly asteroid was not alone
"Some of the more than 200 pits leading to the tunnels are apparently collapsed lava tubes," said the lead researcher. In a study in the journal Geophysical Research Letters. According to him, a stable temperature of about 17 degrees Celsius will allow protection against the extreme changes between day and night. The caves will also provide partial protection from radiation
In addition to its intriguing internal structure (and strange phenomena like diamond rain!), scientists believe that Neptune played an important role in the formation of the solar system and that its composition includes large amounts of gas that was part of the prestellar nebula from which the solar system formed
The key to solving a long-standing mystery about thin disks of gas orbiting young stars: the movement of a small number of charged particles. This is claimed in a new Caltech study
In fact, the environment in these oceans is very similar to the environment of the earth at the time when life began
In addition to all the fascinating landforms discovered on Pluto's surface, the flyby discovered an unusual shape on Charon, a surprising red dome centered on its north pole. Scientists conducted an experiment that simulated the processes in Charon's thin atmosphere
An international team of astronomers found that the gaseous mantle of Jupiter does not have a homogeneous distribution. The inner part has more metals than the outer parts, and they amount to 11 to 30 Earth masses and constitute 3-9% of the total mass of Jupiter. It is likely that these are Jupiter's planets and moons. Bela" at the time of its formation
NASA's Perseverance rover began moving after completing remote science activities at Enchanted Lake. Now scientists want to drive it to the front of the delta of the ancient river that flowed into the lake
A group of researchers proposes to build a spacecraft that will rely on an innovative propulsion system - in which lasers are used to heat hydrogen fuel - that can shorten the flight time to Mars to only 45 days instead of 100
The contract brings NASA one step closer to the first robotic round-trip flight to bring samples safely to Earth through the Mars Sample Return Program
Astronomers rarely use their telescopes just to take pictures. The images in astrophysics are usually created by a process of scientific inference and imagination, the visual expression of which is sometimes an artist's impression of what emerges from the data but there are also some gems that are photographed directly
"Don't Look Up", the new film by Leonardo DiCaprio and Jennifer Lawrence, presents a satirical and poignant look at humanity and the role of the media in the fight against today's major environmental problem
A dramatic ride with an audio track collected during the Jupiter mission's flyby of Ganymede — one of the highlights mission scientists shared in an overview at the fall meeting of the American Geophysical Union
An artistic interpretation of Curiosity's field of view on a mountain on Mars was created by team members who were amazed by the sweeping view
The DART spacecraft that will try to change the orbit of a double asteroid will be launched on 24/11. The producers of Netflix's space disaster film "Don't Look Up," about the discovery of an Earth-threatening asteroid, have scheduled its arrival on Netflix for its scheduled launch day
Scientists from the Weizmann Institute of Science and their partners on NASA's Juno space mission have revealed a series of new findings about the planet Jupiter and found a surprising similarity to Earth
Lucy will fly up to 400 km from the surface of its targets - asteroids that are in sync with the planet Jupiter, and will use its instruments and large antennas to study their geology, including composition, mass, density and volume.
