In the search for life on other planets, scientists traditionally have looked for a world with water. But an Ohio State geophysicist wonders if we should look to rocks instead.
A new quantum algorithm has been implemented for quantum chemical calculations such as Full-CI on quantum computers without exponential/combinatorial explosion, giving exact solutions of Schroedinger Equations for atoms and molecules, for the first time.
Astronomers have captured one of the most detailed views of a young star taken to date, and revealed an unexpected companion in orbit around it.
Now, astronomers have used Hubble to nab a second 'very warm' Neptune (GJ 3470b) that is losing its atmosphere at a rate 100 times faster than that of GJ 436b. Both planets reside about 3.7 million miles from their star. That's one-tenth the distance between our solar system's innermost planet, Mercury, and the Sun.
Magnetic field lines tangled like spaghetti in a bowl might be behind the most powerful particle accelerators in the universe. That's the result of a new computational study by researchers from the Department of Energy's SLAC National Accelerator Laboratory, which simulated particle emissions from distant active galaxies.
UNLV researchers Shangjia Zhang and Zhaohuan Zhu led a team of international astronomers in a study that used the powerful ALMA telescope to discover that in other parts of the Milky Way Galaxy (seen here) there is potentially a large population of young planets -- similar in mass to Neptune or Jupiter -- at wide-orbit that are not detectable by other current planet searching techniques.
A team of astronomers has conducted ALMA's first large-scale, high-resolution survey of protoplanetary disks, the belts of dust and gas around young stars.
The gravitational waves created in the depths of space indeed reach Earth. Their effects, however, are so small that they could only be observed so far using kilometer-long measurement facilities. Physicists therefore discuss whether Bose-Einstein condensates with their ordered quantum properties could also detect these waves. Prof. Ralf Schützhold from HZDR and TU Dresden has now looked at these suggestions and has soberly determined that such evidence is far beyond the reach of current methods.
Previously intractable problems for designing fusion experiments, improving weather models, and understanding astrophysical phenomena such as star formation will be more easily addressed without the need for expensive supercomputers using a new model identified at the University of Wisconsin-Madison.
The effects of a supernova -- and possibly more than one -- on large ocean life like school-bus-sized Megalodon 2.6 million years ago are detailed in a paper just published in Astrobiology.
