The HESS-II (High Energy Stereoscopic System) telescope in Namibia has detected gamma rays of only 30 Giga electron volts (GeV) from the Vela pulsar, the first pulsar to be detected by HESS and the…

Acoustic vibrations – sound waves – are produced by radiation pressure inside stars. While physicists have long posited that young stars vibrate differently than older stars, a new study says it is…

At first glance, Titan, the largest moon of Saturn, has little in common with Earth. Titan's surface temperature dips tp nearly 300 F below zero, its seas slosh with liquid methane, and its sky is a…

We don't know what dark matter is but we know it must be. And now, computer hypothetically, we know it a little better, thanks to new supercomputer simulations showing a possible evolution of…

Surrounding the sun is a vast atmosphere of solar particles, through which magnetic fields swarm, solar flares erupt, and gigantic columns of material rise, fall and jostle each other around.  …

Space looks empty the same way that nature sounds quiet. Unlike nature, space actually is a soundless vacuum, but it's not a void. Invisible to human eyes, space flows with electric activity. NASA is…

We can't even define dark matter, other than it being some blanket term for something that must exist due to unexplainable gravitational influence on the movements and appearance of stars or galaxies…

IAstronomers have discovered a bright, mysterious geologic object in  radar images of Ligeia Mare, the second-largest sea on Saturn's moon Titan. on Scientifically speaking, this is a…

New observations made using NASA's Hubble Space Telescope show that dwarf galaxies are responsible for forming a large proportion of the universe's stars. The result supports a decade-long…

A misconception arises when we ask people about the role that gravity plays in space.  If you watch movies set in space — or for that matter, read statements from NASA —you will be led to think…
