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.
New work from the Carnegie Supernova Project provides the best-yet calibrations for using type Ia supernovae to measure cosmic distances, which has implications for our understanding of how fast the universe is expanding and the role dark energy may play in driving this process. The research was led by Carnegie astronomer Chris Burns.
Researchers have created tiny droplets of the ultra-hot matter that once filled the early universe, forming three distinct shapes and sizes: circles, ellipses and triangles.
Feature describes striking similarity of laboratory research findings with observations of the four-satellite Magnetospheric Multiscale Mission that studies magnetic reconnection in space.
