Space Telescope Science Institute astronomer and data visualization expert Dr. Catherine Zucker and her colleagues have shown how a chain of events beginning...
The solar wind, comprised of solar particles largely made of hydrogen ions, created water on the surface of dust grains carried on asteroids that smashed...
Using the Immersion GRating INfrared Spectrometer (IGRINS) at the Gemini South Observatory on Cerro Pachon, Chile, astronomers have measured carbon-to-hydrogen...
The North Polar Spur and the Fan Region are two bright, large-scale radio structures that are seen on opposite sides of the sky. According to new research,...
New research led by the Observatoire astronomique de l’Université de Genève suggests that water never condensed and that, consequently, oceans never...
Using a technique called gravitational microlensing, which occurs when a star close to Earth momentarily aligns with a more distant star, astronomers have...
The surface pressure on the dwarf planet Pluto is decreasing and that its nitrogen atmosphere is condensing, forming ice on the dwarf planet’s surface,...
In a paper published this week in the journal Astrobiology, researchers focused on the possible existence of the Earth-like phototrophy — the process...
The Sun is the most reliable celestial cue for orientation available to daytime migratory insects. New research led by the University of Exeter shows that...
The 5.8-km-wide (3.6-mile) near-Earth asteroid Phaethon, which is the source of the annual Geminid meteor shower, brightens as it gets close to the Sun....
Using data from NASA’s Parker Solar Probe, a team of solar physicists calculated the distribution of electrons within the electric field of the Sun;...
In 2011, planetary researchers using samples of the solar wind collected by NASA’s Genesis spacecraft found that solar system planetary bodies have a...
Terrestrial planets (Mercury, Venus, Earth, and Mars) are differentiated into three layers: a metallic core, a silicate shell (mantle and crust), and a...
A team of astronomers from Cornell University and the American Museum of Natural History has identified 1,715 stars within 100 parsecs (326 light-years)...
Astronomers using NASA’s Interstellar Boundary Explorer (IBEX) satellite have mapped the boundary of the heliosphere, the vast region of space surrounding...
The Extreme Ultraviolet Imager (EUI), the Heliospheric Imager (SoloHI) and the Metis coronagraph onboard the ESA/NASA Solar Orbiter captured different...
Launched in September 1977, NASA’s Voyager 1 spacecraft flew by Jupiter in 1979 and then Saturn in late 1980. In August 2012, it crossed the heliopause...
