An atmosphere is what makes life on Earth's surface possible, regulating our climate and sheltering us from damaging cosmic rays. But although telescopes have counted a growing number of rocky planets, scientists had thought most of their atmospheres long lost. However, a new study by University of Chicago and Stanford University researchers suggests a mechanism whereby these planets could

About a hundred years ago, geologists first noticed that some volcanic rocks were magnetized opposite to the direction of the local Earth's magnetic field. Thus, the concept of magnetic field reversal was born. Estimates regarding the timing of magnetic field reversals were made about that same time and scientists initially thought that this phenomenon had occurred by the early Pleistocene age.

China has completed feasibility studies of the fourth phase of its lunar exploration program and is expected to build an international lunar research station on the moon's south pole in the future, said Wu Weiren, the chief designer of China's lunar exploration program. In an interview with China Space News, Wu said that three missions are planned for the fourth phase of the lunar explorat

In order to withstand the rigors of space on deep-space missions, food grown outside of Earth needs a little extra help from bacteria. Now, a recent discovery aboard the International Space Station (ISS) has researchers may help create the 'fuel' to help plants withstand such stressful situations. Publishing their findings to Frontiers in Microbiology, researchers working with NASA describ

The NANOGrav Collaboration recently captured the first signs of very low-frequency gravitational waves. Prof. Pedro Schwaller and Wolfram Ratzinger analyzed the data and, in particular, considered the possibility of whether this may point towards new physics beyond the Standard Model. In an article published in the journal SciPost Physics, they report that the signal is consistent with both a ph

Airbus has been selected by the European Commission to study spacecraft manufacturing in space through the Horizon 2020 Programme. The PERIOD (PERASPERA In-Orbit Demonstration) project focuses on satellite assembly and manufacturing in orbit. This A/B1 phase study contract, worth 3 million euro, will last two years, with the objective to continue with a demonstrator in orbit. The "orbital

Almost all launch vehicles and large missiles liftoff from the ground in the vertical direction and continue toward some objective. For space launch systems the objective is achieving orbit through the use of ascent trajectories that are usually optimized for weather and mission conditions in order to maximize performance while maintaining conservative safety margins. The actual shape of a

Looking at the night sky, one's thoughts might be drawn to astrochemistry. What molecules inhabit the vast spaces between the stars? Would we see the same molecules that surround us here on Earth? Or would some of them be more exotic--something rarely observed or even unknown? Recent research by a multinational team led by Prof. Robert Koos from the Institute of Physical Chemistry of the P

From activities in low-Earth orbit to NASA's Artemis program, the commercial space industry has emerged as an innovator in areas of space access, commerce, and exploration. In an effort to address the growth of commercial space over the past decades and inform the relationship between government and industry for the future, NASA will host a virtual event Wednesday, March 17, through Friday, Marc

After 20 years of continuous habitation, the International Space Station has entered its "Golden Age" and is abuzz with activity - thanks in large part to the return of US rocket launches via commercial partner SpaceX. But though the near- future of this symbol of post-Cold War cooperation is assured, NASA wants to begin disengaging by the end of the decade, leaving a gap that the private s
