Scientists at the University of Oxford may have solved one of the biggest questions in modern physics, with a new paper unifying dark matter and dark energy into a single phenomenon: a fluid which possesses 'negative mass." If you...
A study led by Texas Tech University shows that supersoft X-ray emissions can come from accretion as well as nuclear fusion.
For decades, astronomers and astrophysicists have used a specific type of supernova to measure the expansion of the universe....
By developing a new method for measuring isotopic ratios of water and carbon dioxide remotely, scientists have found that the water in Saturn's rings and satellites is unexpectedly like water on the Earth, except on Saturn's moon Phoebe, where...
An international team of scientists have detected ripples in space and time, known as gravitational waves, from the biggest known black-hole collision that formed a new black hole about 80 times larger than the Sun – and from another...
Telescope and Rapid Response System (Pan-STARRS), and the NASA Kepler space telescope
A supernova discovered by an international group of astronomers including Carnegie's Tom Holoien and Maria Drout, and led by University of Hawaii's Ben Shappee, provides an unprecedented look...
An international research team including The Australian National University (ANU) has used the Kepler space telescope in coordination with ground-based telescopes to witness the first moments of a star dying in unprecedented detail.
The astronomers witnessed the star dying a...
Based on computer simulations and new observations from the Atacama Large Millimeter/submillimeter Array (ALMA), researchers have found that the rings of gas surrounding active supermassive black holes are not simple donut shapes. Instead, gas expelled from the center interacts...
From their laboratories on a rocky planet dwarfed by the vastness of space, Clemson University scientists have managed to measure all of the starlight ever produced throughout the history of the observable universe.
Astrophysicists believe that our universe, which is...
Experimental atomic clocks at the National Institute of Standards and Technology (NIST) have achieved three new performance records, now ticking precisely enough to not only improve timekeeping and navigation, but also detect faint signals from gravity, the early universe...
The Big Bang theory and the question of how life on Earth began has fascinated scientists for decades, but now new research from The University of Western Australia suggests the conditions that resulted from the Big Bang are different...
Astronomers have gleaned some of the best data yet on the composition of a planet known as HR 8799c -- a young giant gas planet about 7 times the mass of Jupiter that orbits its star every 200 years.
The...
