NASA and European Space Agency (ESA) are moving to the next phase in a campaign to deepen understanding of whether life ever existed on Mars and, in turn, better understand […]
Hubble pins down weird exoplanet with a far-flung orbit
(Newswise)–A planet in an unlikely orbit around a double star 336 light-years away may offer a clue to a mystery much closer to home: a hypothesized, distant body in the […]
Warm oceans helped first human migration from Asia to North America
(Newswise)–New research reveals significant changes to the circulation of the North Pacific and its impact on the initial migration of humans from Asia to North America. The new international study […]
Researchers reveal switch used in plant defense against animal attack
(Newswise)–For decades, scientists have known that plants protect themselves from the devastation of hungry caterpillars and other plant-munching animals through sophisticated response systems, the product of millions of years of […]
Buzz kill: Ogre-faced spiders ‘hear’ airborne prey with their legs
(Newswise)–In the dark of night, ogre-faced spiders with dominating big eyes dangle from a silk frame to cast a web and capture their ground prey. But these spiders also can […]
NASA’s OSIRIS-REx Spacecraft successfully touches asteroid
NASA’s Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorer (OSIRIS-REx) spacecraft unfurled its robotic arm Tuesday, and in a first for the agency, briefly touched an asteroid to collect dust […]
Studying the sun as a star to understand stellar flares and exoplanets
(Newswise)–New research shows that sunspots and other active regions can change the overall solar emissions. The sunspots cause some emissions to dim and others to brighten; the timing of the […]
Global survey using NASA data shows dramatic growth of glacial lakes
In the largest-ever study of glacial lakes, researchers using 30 years of NASA satellite data have found that the volume of these lakes worldwide has increased by about 50% since […]
Hubble uses Earth as a proxy for identifying oxygen on potentially habitable planets around other stars
(Newswise)–Taking advantage of a total lunar eclipse, astronomers using NASA’s Hubble Space Telescope have detected Earth’s own brand of sunscreen – ozone – in our atmosphere. This method simulates how […]
A new idea on how Earth’s outer shell first broke into tectonic plates
(Newswise)–The activity of the solid Earth – for example, volcanoes in Java, earthquakes in Japan, etc.- is well understood within the context of the ~50-year-old theory of plate tectonics. This […]
