Experts say scientific understanding of deep hydrocarbons has been transformed, with new insights gained into the sources of energy that could have catalyzed and nurtured Earth's earliest forms of life. Abiotic hydrocarbons have been a major focus of the Deep Carbon Observatory program -- a 10-year exploration of Earth's innermost secrets, concluding in October.
This incredible image of the hourglass-shaped Southern Crab Nebula was taken to mark the NASA/ESA Hubble Space Telescope's 29th anniversary in space. The nebula, created by a binary star system, is one of the many objects that Hubble has demystified throughout its productive life. This new image adds to our understanding of the nebula and demonstrates the telescope's continued capabilities.
A research team at Toyohashi University of Technology has developed a new concept of fire extinguishing, named Vacuum Extinguish Method. VEM is based on the "reverse" operation of the conventional fire extinguishing procedure; It sucks the combustion products, even flame and the firing source itself into a vacuum chamber to clean up the firing zone. This concept is advantageous for space use, as it prevents the spread of harmful combustible products throughout the enclosed cabin.
Scientists have long known that Earth and Mercury have metallic cores. Like Earth, Mercury's outer core is composed of liquid metal, but there have only been hints that Mercury's innermost core is solid. Now, in a new study, scientists report evidence that Mercury's inner core is indeed solid and that it is very nearly the same size as Earth's solid inner core.
How do you explore the interior of a planet without ever touching down on it? Start by watching the way the planet spins, then measure how your spacecraft orbits it -- very, very carefully. This is exactly what NASA planetary scientists did, using data from the agency's former mission to Mercury.
A stellar flare 10 times more powerful than anything seen on our sun has burst from an ultracool star almost the same size as Jupiter.
To confirm the presence of a planet, it is necessary to wait until it has made one or more revolutions around its star. This can take from a few days for the closest to the star to decades for the furthest away. Only a telescope dedicated to the search for exoplanets can carry out such measurements over such long periods of time, which is the case of the EULER telescope of UNIGE.
An international team led by Professor XUE Yongquan from University of Science and Technology announced their observation of a unique X-ray signal from 6.6 billion light years away, which provides new insights into the physics of neutron stars.
In as few as 25 years, climate change could shrink and dry 60-80% of Western Hemisphere cloud forests, finds a study published today. If greenhouse gas emissions continue increasing as they have been, 90% of Western Hemisphere cloud forests would be affected as early as 2060. The current cloud and frost environment of the highly diverse alpine ecosystems above these equatorial cloud forests, known as páramo, will nearly disappear.
A team of astronomers, including Nader Haghighipour from the Institute for Astronomy at the University of Hawaii at Manoa, discovered a third planet in the circumbinary planetary system Kepler-47.
