At a recent interstellar conference, some of the biggest names in starship design came together to formulate how we might reach out to another star.
Measuring the age of stars has been a notoriously difficult proposition, but now astronomers can pin down stellar chronology to a better precision than ever.
After carefully measuring the masses of small, rocky exoplanets, astronomers have come to the conclusion that our solar system may not be unique.
Mars' atmosphere is often viewed as frigid and unchanging, but in studies of the red planet's aeolian processes, nothing could be further from the truth -- particularly where Martian dust devils are concerned. Continue reading →
A NASA-backed study explores an innovative way to dramatically cut the cost of a human expedition to Mars -- put the crew in stasis.
Cubesats provide a valuable low-cost research space platform for institutions, universities, laboratories and space agencies, but could their use create a new hazard for the increasingly crowded orbital environment? Continue reading →
Through the analysis of isotopes trapped inside ancient quartz crystals, geochemists have realized that the Earth-shattering cosmic impact that laid waste to our young Earth and formed the moon happened 60 million years earlier than thought.
