Team solves the origin of the Moon's 'mascons' mystery
A mystery of the moon that imperiled astronauts and spacecraft on lunar missions has been solved by a Purdue University-led team of scientists as part of NASA's GRAIL mission.
Researchers find winds on Uranus and Neptune confined to thin atmosphere layer
A brighter method to determine surface gravity of distant stars
Astronomers have found a clever new way to slice and dice the flickering light from a distant star in a way that reveals the strength of gravity at its surface.
Earth’s other moons
(PhysOrg.com) -- Earth usually has more than one moon, according to a team of astronomers from the University of Helsinki, the Paris Observatory and the University of Hawaii at Manoa.
Light from galaxy clusters confirms theory of relativity
All observations in astronomy are based on light emitted from stars and galaxies and, according to the general theory of relativity, the light will be affected by gravity. At the same time all interpretations ...
Researchers replicate white dwarf photospheres in lab using X-ray machine
Computer model shows strong magnetic fields may alter alignment of black hole accretion disks and plasma jets
Why Einstein will never be wrong
One of the benefits of being an astrophysicist is your weekly email from someone who claims to have "proven Einstein wrong". These either contain no mathematical equations and use phrases such as "it is obvious ...
GRAIL creates most accurate Moon gravity map (w/ video)
(Phys.org)—Twin NASA probes orbiting Earth's moon have generated the highest resolution gravity field map of any celestial body.
Liquid spacetime: A very slippery superfluid, that's what spacetime could be like
What if spacetime were a kind of fluid? This is the question tackled by theoretical physicists working on quantum gravity by creating models attempting to reconcile gravity and quantum mechanics. Some of ...
Grey is the new black hole: is Stephen Hawking right?
Over the past few days, the media has cried out the recent proclamation from Stephen Hawking that black holes, a mystery of both science and science fiction, do not exist. ...
Why does Venus' atmosphere rotate sixty times faster than its surface?
Venus is a slowly rotating planet since it takes about two hundred and forty three terrestrial days to complete a round about itself. Its atmosphere is expected to rotate with the same rhythm as well, but ...
How plants sense touch, gravity and other physical forces
(PhysOrg.com) -- At the bottom of plants' ability to sense touch, gravity or a nearby trellis are mechanosensitive channels, pores through the cells' plasma membrane that are opened and closed by the deformation ...
Newly discovered celestial object defies categories
An object discovered by astrophysicists at the University of Toronto (U of T) nearly 500 light years away from the Sun may challenge traditional understandings about how planets and stars form.
