New observations reveal that Mars could still be volcanically active, raising the possibility for habitable conditions in the near surface of Mars in recent history. Ongoing research investigates the possibility that the most recent volcanic activity on Mars, which occurred about 50,000 years ago, might have been triggered by a nearby asteroid impact that happened around the same time.
How a planet comes together has implications for whether it captures and retains the volatile elements, including nitrogen, carbon and water, that eventually give rise to life, according to scientists at Rice University.
New Johns Hopkins University simulations offer an intriguing look into Saturn's interior, suggesting that a thick layer of helium rain influences the planet's magnetic field.
A new map of the Schrodinger basin of the moon could help guide future exploration missions. The map project was supported by NASA and created by a team of researchers including a University of Arkansas graduate student.
Astronomers have identified more than 4,000, and counting, confirmed exoplanets -- planets orbiting stars other than the sun -- but only a fraction have the potential to sustain life. Now, new research from UBC's Okanagan campus is using the geology of early planet formation to help identify those that may be capable of supporting life.
NASA's Hubble Space Telescope is giving astronomers a rare look at a Jupiter-sized, still-forming planet that is feeding off material surrounding a young star.
New observations of Venus from Earth reveal some of Venus's most basic properties, including the precise length of a day on Venus, the tilt of its axis and the size of its core.
Researchers at the National Institute of Standards and Technology (NIST) are now measuring tinier moon dust particles than ever before, a step toward more precisely explaining the Moon's apparent color and brightness. This in turn might help improve tracking of weather patterns and other phenomena by satellite cameras that use the Moon as a calibration source.
An international collaboration of astronomers has detected a new chemical signature in the atmosphere of an extrasolar planet (a planet that orbits a star other than our Sun). The hydroxyl radical (OH) was found on the dayside of the exoplanet WASP-33b -- a so-called 'ultra-hot Jupiter', a gas-giant planet orbiting its host star much closer than Mercury orbits the Sun and therefore reaching atmospheric temperatures of more than 2,500° C.
Analog astronauts--scientists living in a habitat atop a Hawaiian volcano to train for living and working on the moon and Mars--are exploring lava tubes, which may hold biosignatures of life. The researchers will present their latest findings at the European Geosciences Union (EGU) General Assembly 2021, which is meeting from 19-30 April 2021.
