The inner core of the Earth, a hot and dense ball of solid iron located more than 5,000 kilometers deep, is the most inaccessible place on our planet. Now, a Chinese scientific team has found that its rotation could recently stop and be inverting. The results of the research, based on the analysis of dozens of earthquakes, are published in the journal Nature Geoscience, and, according to its authors, this variation is correlated with changes in geophysical observations on the Earth's surface, such as the magnetic field and the duration of the day The article is signed by Xiaodong Song…

If you traveled to Mars tomorrow, what wouldwhat clothes would you take in the suitcase? A jacket in case it gets cold or a swimsuit to withstand the heat? About two Earth years ago (or about 250 Martian days, depending on how you look at it), Spain deployed a small but powerful meteorological network on the red planet to monitor temperature, wind, humidity and Martian dust. This Monday, after a detailed analysis of these parts of space time, the team of Spanish scientists in charge of this project presents the most comprehensive photograph to date of Martian time. And pay…

A group of astronomers you have located more than 200 stars known as RR Lyrae in the stellar halo of the Milky Way and the most distant is more than a million light years from earth, almost half the distance to our neighboring galaxy, Andromeda. RR Lyrae are among the oldest stars in our galaxy and have physics that cause them to expand and contract in a regular cycle, making them sort of like standard candles for measuring galactic distances. The new study from the University of California at Santa Cruz (USA) is presented at the meeting held this week…

Several major launches designed to explore different corners of the Solar System are expected this year. 2023 will also be a year of space news. In the coming months, the launch of several important scientific missions Considerations for exploring different corners of the Solar System. I know will launch a probe to the moons of Jupiter. There will also be several launches focused on the study of enigmatic and distant asteroids. Lunar exploration plans will continue with the takeoff of several satellites Y some other technical test so that, one day, humanity can step on the Moon again to go…
