When the DART spacecraft crashed into the dimorphous asteroid, the body of the spacecraft hit between two large rocks and the two solar panels hit the rocks themselves. The yellow surface is a digital ground model of the impact site prepared from DART images, and the image of the DART spacecraft shows its position a few tens of milliseconds before impact. The white line coming out of the back of the spacecraft shows the trajectory of the spacecraft. The length of the spacecraft's body was about 1.30 meters from front to back.

These dark spots on the Sun, visible in ultraviolet light, are called coronal holes and are areas where fast solar wind bursts out into space. By chance, they managed to take a photo that looked like the sun was smiling.

"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

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
