Supernovae-stellar explosions as bright as an entire galaxy-have fascinated us since time immemorial. Yet, there are more hydrogen-poor supernovae than astrophysicists can explain. Now, a new Assistant Professor at the Institute of Science and Technology Austria (ISTA) has played a pivotal role in identifying the missing precursor star population. The results, now published in Science, go back t

Astronomers at the University of Toronto have discovered a population of massive stars that have been stripped of their hydrogen envelopes by their companions in binary systems. The findings, published in Science, shed light on the hot helium stars that are believed to be the origins of hydrogen-poor core-collapse supernovae and neutron star mergers. For over a decade, scientists have theo

Scientists have known that the giant plume of ice grains and water vapor spewing from Saturn's moon Enceladus is rich with organic compounds, some of which are important for life as we know it. Now, scientists analyzing data from NASA's Cassini mission are taking the evidence for habitability a step further: They've found strong confirmation of hydrogen cyanide, a molecule that is key to the ori

For many years, scientists have predicted that many of the elements that are crucial ingredients for life, like sulfur and nitrogen, first came to Earth when asteroid-type objects carrying them crashed into our planet's surface. But new research published by our team in Science Advances suggests that many of these elements, called volatiles, may have existed in the Earth from the beginning

Earth planning date: Wednesday, December 13, 2023: With the colder months upon those of us in the Northern Hemisphere, some may be thinking about warmer times ahead, be it the return of spring, or a vacation to briefly thaw out from winter. The arrival of winter spells colder temperatures and fewer daylight hours, along with bouts of snow and ice for many. Slippery conditions make for mor

In our last post, we described how VIPER, NASA's first robotic Moon rover, is using artificial intelligence to create several options for the VIPER team to plan the rover's path during its mission to the lunar South Pole. Today, we'll share more about how AI also is used to help human operators drive VIPER and create highly accurate maps of the rover's mission area on the Moon. Like

Growing food aboard the International Space Station is one of the many research investigations ripe for long duration spaceflight missions to the Moon and Mars. NASA astronaut Frank Rubio recently shared the saucy story of two rogue tomatoes, which he had accidentally lost track of while harvesting for the eXposed Root On-Orbit Test System (XROOTS) experiment he conducted aboard the space
