Comet probe Rosetta detects the 'most wanted molecule'
ESA's Rosetta spacecraft has made the first measurement of molecular nitrogen at a comet, providing clues about the temperature environment in which Comet 67P/Churyumov-Gerasimenko formed.
Satellite images reveal ocean acidification from space
Pioneering techniques that use satellites to monitor ocean acidification are set to revolutionise the way that marine biologists and climate scientists study the ocean. This new approach, that will be published ...
Astrophysicists find five-planet system with most Earth-like exoplanet yet
(Phys.org) —NASA's Kepler mission has discovered two new planetary systems that include three super-Earth-size planets in the "habitable zone," the range of distance from a star where the surface temperature ...
Scientists discover cosmic factory for making building blocks of life
Scientists have discovered a 'cosmic factory' for producing the building blocks of life, amino acids, in research published today in the journal Nature Geoscience.
Study uncovers forces that hold gravity-defying near-earth asteroid together (Update)
Researchers at UT have made a novel discovery that may potentially protect the world from future collisions with asteroids.
At the solar system's edge, more surprises from Voyager
(Phys.org) —Data from NASA's Voyager 1 spacecraft continues to provide new insight on the outskirts of our solar system, a frontier thought to be the last that Voyager will cross before becoming the first ...
Fireballs in Jupiter's atmosphere observed by amateur astronomers
The solar system is crowded with small objects like asteroids and comets. Most have stable orbits which keep them out of harm's way, but a small proportion of them are in orbits that risk them colliding with ...
Galaxies without stars: The problem of the missing hydrogen in the early Universe
(Phys.org)—Hydrogen is the most common element in the Universe, making up 75% of all normal matter and the content of stars. Although stars themselves are hot, they can only form out of the coldest gas ...
Gemini Planet Imager captures best photo ever of an exoplanet
If Earth falls, will interstellar space travel be our salvation?
Some climatologists argue it may be too late to reverse climate change, and it's just a matter of time before the Earth becomes uninhabitable – if hundreds of years from now. The recent movie Interstellar ...
Analysis of Sutter's Mill fragments reveals organic compounds not seen in other meteorites
Near-Earth asteroid is really a comet
Some things are not always what they seem—even in space. For 30 years, scientists believed a large near-Earth object was an asteroid. Now, an international team including Joshua Emery, assistant professor ...
Two Russians turn cable guys in record spacewalk (Update)
In a record-long spacewalk, Russian cosmonauts rigged cable outside the International Space Station on Friday for a new lab that's due to arrive in a few months.
Shutdown makes US 'less desirable' for science
The US government shutdown puts international science collaboration in peril and could have far-reaching impacts on innovation and research, a top science group said Wednesday.
