| It is gravitationally captive to the giant ball of ringed gases that is Saturn. |
|
| Their right-handed partners would inhabit a world existing alongside ours, but interacting only gravitationally. |
|
| A US and Netherlands-led team of astronomers using the Hubble Space Telescope have identified 19 new examples of gravitationally lensed galaxies. |
|
| This happens because the massive black hole gravitationally attracts any matter lurking near it and never lets it go. |
|
| The evidence for gravitationally repulsive dark energy is strong, but there are gaps in our knowledge. |
|
| The supernova observations call out for some gravitationally repulsive substance to drive the cosmic acceleration. |
|
| To move an object away from a gravitationally attracting mass requires energy. |
|
| A system of double stars that are gravitationally bound and are in orbit around each other are called binary stars. |
|
| A galaxy is a gravitationally bound system containing billions of stars along with interstellar gases and dust. |
|
| A joint paper, due out in a few months, will look into the gravitationally driven sea-level changes a melting Greenland could trigger. |
|
| Dark matter particles are expected to interact only gravitationally with the baryons in the galaxy, rendering them difficult to detect. |
|
| But these giant planets act as powerful shields, gravitationally deflecting the long-period comets away from the inner planetary system. |
|
| A compact bodies is created when a larger entity gravitationally collapses, increasing the field strength. |
|
| The pattern of polygonal ridges bounding dish-shaped depressions is interpreted as the product primarily of embryonic overturn of this gravitationally unstable system. |
|
| In 1995 the HST recorded one of the most spectacular examples of a gravitationally lensed astronomical system. |
|
| Since only a fraction of the cloud condenses into stars, the huge mass of the rest of the cloud gravitationally holds the cluster together. |
|
| Since everything in the universe is gravitationally pulling at everything else, we would expect the expansion to be slowing. |
|
| The process generally consumes the kinetic energy of an object launched outwards from the gravitationally attracting body. |
|
| Dr. Hickson's research involves both remote and nearby galaxies, studying the formation and evolution of these gravitationally bound systems. |
|
| These clusters are gravitationally bound, meaning that gravity prevents the individual stars within the cluster from heading off into intergalactic space. |
|
|
|
| When observed, clusters appear to be collections of galaxies held together by mutual gravitational attraction, yet velocities are far too great for them to remain gravitationally bound. |
|
| Every so often, one will be gravitationally bumped out from the cloud and begin a long solo orbit around the sun. |
|
| The discovery of neutron stars sparked interest in gravitationally collapsed compact objects as a possible astrophysical reality. |
|
| Future observers would find themselves in an almost empty Universe, in the company of only the few nearby galaxies that happened to be gravitationally bound to their own. |
|
| A few hundred compact, spherical clusters called globular clusters exist in the disc and halo of our Milky Way and are gravitationally bound to our Galaxy. |
|
| In addition to the Sun and the planets, there are millions of smaller objects that are gravitationally bound to the Sun as part of our solar system. |
|
| His proposed observation requires monitoring the X-ray emissions from gravitationally lensed quasars. |
|
| Such an expansion is really only possible if the Universe contains very little matter, as all matter, whether visible or dark, interacts gravitationally to slow down the expansion rate. |
|
| Consider that the person asking is Mr. Bean, the diminutive, awkward, gravitationally challenged, accident-prone incarnation served up by Rowan Atkinson. |
|
| LightSail-2 would aim to do a longer flight in a higher Earth orbit, and LightSail-3 would fly to the gravitationally stable L1 Lagrangian point between the Earth and sun. |
|
| Over the next 40,000 years or so, the three knots of gas will turn into young stars, creating a gravitationally bound quadruple star system, researchers report in the Feb. |
