The net gravitational field at any point on the surface of the earth is the sum of the gravitational fields of all the masses in the universe; hence it displays diurnal and seasonal variations and variations with the phases of the moon and Jupiter; and those variations vary with latitude: if you live far from the poles, you weigh more at night.
Translate from English to Spanish

The sun exerts a stronger gravitational pull on the moon than does the earth.
Translate from English to Spanish

Translate from English to Spanish

Due to Triton's retrograde orbit, its density, and its composition, astronomers theorize that Triton was not originally a satellite of Neptune, but was captured by Neptune's gravitational pull, forcing it into an orbit around the planet.
Translate from English to Spanish

Astronomers think that if it were not for the giant planet Jupiter exerting its gravitational force on the asteroids in the belt, the inner planets would be constantly bombarded by large asteroids.
Translate from English to Spanish

The gravitational pull of a black hole is so powerful that even light cannot escape from it.
Translate from English to Spanish

Newton explained the movement of orbiting planets as the result of motion along a straight line combined with the gravitational pull of the Sun. His laws are all based on the idea that nothing is naturally at rest. He reasoned that all heavenly bodies are constantly moving, with no limits on space and time.
Translate from English to Spanish

Mariner 10 used the gravitational pull of Venus to swing it into a different orbit so it could continue on to Mercury.
Translate from English to Spanish

Translate from English to Spanish

The strength of the gravitational force reduces quickly with distance.

Scientists have announced that they have discovered gravitational waves.

Juno will map Jupiter's gravitational and magnetic fields.

By mapping Jupiter's gravitational and magnetic fields, Juno will reveal the planet's interior structure and measure the mass of the core.

If mass curves space, then very large masses moving quickly through space would create ripples in space. These are called gravitational waves.

Gravitational waves are very hard to detect.

The Laser Interferometer Space Antenna (LISA) is a space mission that will be able to detect gravitational waves.

LISA will place three spacecraft in orbit around the Sun, tagging along behind Earth. The three spacecraft will be 5 million kilometers apart flying in a triangle formation. When a gravitational wave passes by, these ripples in space gently push the spacecraft around by the tiniest amount imaginable. But the super-super-super sensitive laser beams that connect the three spacecraft will allow this tiny movement to be measured.

LISA will look for gravitational waves from stars and black holes.

Scientists have detected gravitational waves.

The gravitational waves were generated by the merger of two black holes.

Europe's VIRGO detector has detected gravitational waves for the first time.

One of the most spectacular achievements in physics so far this century has been the observation of gravitational waves, ripples in space-time that result from masses accelerating in space.

So far, there have been five detections of gravitational waves, thanks to the Laser Interferometer Gravitational-Wave Observatory (LIGO) and, more recently, the European Virgo gravitational-wave detector.

When galaxies collide, their central black holes tend to spiral toward each other, releasing gravitational waves in their cosmic dance.

Much as a large animal like a lion produces a deeper roar than a tiny mouse's squeak, merging supermassive black holes create lower-frequency gravitational waves than the relatively small black holes LIGO and similar ground-based experiments can detect.

Because their rapid pulse of radio emission is so predictable, a large array of well-understood pulsars can be used to measure extremely subtle abnormalities, such as gravitational waves.

The North American Nanohertz Observatory for Gravitational Waves (NANOGrav) is one of the leading groups of researchers using pulsars to search for gravitational waves.

Tides are caused by gravitational pull of the moon and the sun.

A consortium of astronomers said Thursday they had for the first time confirmed a prediction of Albert Einstein's theory of general relativity by observing the gravitational effects of a supermassive black hole on a star zipping by it.

Einstein had posited that large gravitational forces could stretch light, much like the compression and stretching of sound waves we perceive with the change of pitch of a passing train.

Black holes are so dense that their gravitational pull can trap even light.

Scientists detected gravitational waves for the first time in 2015, using LIGO.

Ocean currents, the upwelling of cold water from the deep ocean, winds, movements of heat and freshwater, and Earth’s gravitational pull all play a role in moving water masses around.

It's possible to calculate the Earth's mass using a formula that includes the Moon's rotation period around the sun, the average distance between the Earth and the Moon, the gravitational context and the number π.

Of two balls of the same size (one made of iron, the other of wood) falling from the top of a tower, the iron one, because it has a greater gravitational charge (being heavier), is attracted with greater force, but, on the other hand, precisely because it has more mass (inertia), it offers greater resistance to falling. The result: both touch the ground at the same time, as Galileo demonstrated.

Thomas understands that natural laws and forces, space-time, electromagnetic and gravitational fields, energy, atoms, stars, galaxies, life, everything, in short, had its origin in an indescribable singularity that mysteriously exploded: the Big Bang.

Time slows down at high speed, and space bends in the presence of gravitational fields.

Scientists at the U.S. space agency, NASA, say they’ve been able to observe, for the first time from lunar orbit, a “bulge” in the moon caused by the “gravitational tug-of-war with Earth.”

It finds planets using a technique called the radial-velocity method, which measures changes in the speed of a star's movement toward or away from earth caused by the gravitational tug of an orbiting planet.

If you stood on one of its moons, would you be able to notice Jupiter's gravitational pull?

It is obvious that, because of the moon's changing position with respect to the earth and sun during the monthly cycle of phases (29.53 days) the gravitational attraction of moon and sun may variously act along a common line or at changing angles relative to each other.

By studying the gravitational wave signal, the team discerned this ripple in the cosmic fabric was likely created by the merger or collision of two black holes, about 85 and 66 times the mass of the sun, respectively.

The new research provides the first solid evidence that the universe went through an extraordinary growth spurt in its first brief moments of being, a period called inflation. This unfathomably rapid rate of growth left ripples in the fabric of space—gravitational waves that Albert Einstein predicted, but that had never been detected until now.

Scientists at the LIGO and VIRGO observatories detected and confirmed the first gravitational waves produced by the collision and merger of a black hole with a neutron star, not once but twice within 10 days of each other. Previously confirmed gravitational wave detections were the results of either the collisions of a black hole and another black hole or a neutron star with a neutron star, not one of each.

It seems there are always members of the scientific community who are eager for the chance to knock the air out of Albert Einstein's nearly 100 year-old General Theory of Relativity. This milestone work describes how the elemental force of gravity helps to shape the geometry of space and time. And some of its predictions — involving phenomena like the dilation of time, the motion of bodies in free fall and the gravitational bending of light — are mind-bendingly different than those of classical physics.

Using telescopes located in New Zealand and Tasmania, the research team took advantage of an astronomical phenomenon that’s known as gravitational microlensing.
