Escalating political tensions between America and Russia now
threaten the future of the International Space Station and other future
joint space projects.
An exoplanet that orbits its star at a whopping distance of
2,000 times the sun-Earth distance has been discovered -- as far as
exoplanets go, that's the most extreme orbit found to date.
Astronomers have long been in the dark about what is
happening just beyond the center of the Milky Way -- but with the help
Cepheid variable stars, we're beginning to realize that our galaxy's
outer disk is mysteriously flared.
Three crewmembers of the International Space Station have
returned safely to Earth, ending their six-month orbital mission.
Rumors of interfering galactic dust messing with the
potentially historic BICEP2 detection of gravitational waves have been
shot down by project scientists.
What happens when two neutron stars collide? Using a
sophisticated computer simulation, NASA scientists have visualized this
violent scenario in awesome degenerate-matter-crushing detail.
On Tuesday evening (May 13), as the moon, just one night from
full phase rises in the east-southeast sky it will be accompanied by a
very bright yellowish-white 'star' shining off to its lower left. That
'star' will be the planet Saturn.
There are many mysteries about the enigmatic ringed gas
giant, but the curious mechanism behind Saturn's 'spokes' is one of the
more intriguing puzzles.
