MIT PhD candidate Lanie McKinney is developing technology to convert the chemicals in the Martian atmosphere into propellant to bring astronauts home.
Scientists theorize that the rapid emergence of supermassive black holes (SMBHs) in the early Universe can be explained by the direct-collapse black hole (DCBH) scenario. In a recent study, astronomers investigated the potential host environments of DCBHs and found that this scenario is a plausible explanation for how the "seeds" of SMBH formed.

On Sept. 19, 1959, the paper “Searching for Interstellar Communications” was published. Printed in the respected scientific journal Nature and written by Cornell University physicists Giuseppe Cocconi and Philip Morrison, the work established a scientific framework and legitimacy for a field that previously lacked credibility. Cocconi and Morrison examined methodologies for humans’ search for extraterrestrial Continue reading "Sept. 19, 1959: A SETI kickstart" The post Sept. 19, 1959: A SETI kickstart appeared first on Astronomy Magazine .
A massive crater on Mars’ moon Phobos may hide a dense region of compressed material that could reveal whether the moon is a captured asteroid or debris from an ancient impact on Mars. Japan’s upcoming MMX sample return mission could provide the measurements and physical evidence needed to solve the mystery.
