Hydrogen is a key building block of the cosmos. Whether stripped down to its charged core, or piled into a molecule, the nature of its presence can tell you a lot about the Universe’s features on the largest of scales.

For that reason astronomers are very interested in detecting signals from this element, wherever it can be found.

Now the light signature of uncharged, atomic hydrogen has been measured further from Earth than ever before, by some margin. The Giant Metrewave Radio Telescope (GMRT) in India has picked up a signal with a lookback time – the time between the light being emitted and being detected – of a huge 8.8 billion years.

In this interview with Avi Loeb, the Frank B. Baird, Jr., Professor of Science and astrophysicist at Harvard University, he explains why in his new book, Extraterrestrial: The First Sign of Intelligent Life Beyond Earth, he has put forth the theory that our first interstellar visitor to be spotted in our solar system, Oumuamua, might just be the first sign of intelligent life beyond earth.

The largest moon of Saturn is an unique habitat in our Solar System. It appears to be a world different from our own, with its methane-filled lakes, freezing volcanoes, and underground tunnels.

However, Titan’s first geomorphological map demonstrates that, while its landscape is spectacular and diverse, these elements actually make it surprisingly similar to Earth.

Chinese scientists precisely confirmed the latest volcanic activity on moon happened about 2 billion years ago after they studied the lunar samples collected by Chang’e-5 lunar probe in 2020.

The outcome was announced by the China National Space Administration on Monday.

In 2021, a team of scientists carried out researches on the volcanic rock, which is a type of basalt to help indicate the time of volcanic activity occurred, from the lunar samples and proved that the volcanic activity continued until 2 billion years ago, a new refresh for human beings toward the lunar magmatic activity and the lunar evolution.

Exoplanet LH 475b has a radius about 99 percent the size of Earth’s, but that rocky radius is surrounded by either a choking atmosphere of carbon dioxide — or the vacuum of space, according to recent observations with the James Webb Space Telescope (JWST). But it’s definitely a planet, and that’s something astronomers couldn’t say for sure until now.

Astronomer Jacob Lustig-Yeager, of the Johns Hopkins University Applied Physics Laboratory, presented their work at the 241^st meeting of the American Astronomical Society.

Researchers using NASA

Established in 1958, the National Aeronautics and Space Administration (NASA) is an independent agency of the United States Federal Government that succeeded the National Advisory Committee for Aeronautics (NACA). It is responsible for the civilian space program, as well as aeronautics and aerospace research. Its vision is “To discover and expand knowledge for the benefit of humanity.” Its core values are “safety, integrity, teamwork, excellence, and inclusion.” NASA conducts research, develops technology and launches missions to explore and study Earth, the solar system, and the universe beyond. It also works to advance the state of knowledge in a wide range of scientific fields, including Earth and space science, planetary science, astrophysics, and heliophysics, and it collaborates with private companies and international partners to achieve its goals.

Russia announced on January 11, 2023, that it would send a rescue vessel to the International Space Station to bring home three astronauts. Roscosmos cosmonauts Sergei Prokopyev and Dmitry Petelin, along with NASA astronaut Frank Rubio have in effect been stranded since their original capsule was damaged. US and Russian space officials believe the Soyuz MS-22 started leaking in December 2022 after it was hit by a tiny meteoroid.

The Space Solar Power Project (SSPP) began in 2011 when Donald Bren — philanthropist, chairman of the Irvine Company, and a lifetime member of the Caltech Board of Trustees — and Caltech’s then-president Jean-Lou Chameau came together to discuss the potential for a space-based solar power research project. By 2013, Bren and his wife (Caltech trustee Brigitte Bren) began funding the project through the Donald Bren Foundation, which will eventually exceed $100 million. As Bren said in a recent Caltech press release:

“For many years, I’ve dreamed about how space-based solar power could solve some of humanity’s most urgent challenges. Today, I’m thrilled to be supporting Caltech’s brilliant scientists as they race to make that dream a reality.”
