Such a mission could be developed soon, allowing astrophysicists to take selfies of the solar system and use the Sun’s gravity as a lens to peer deep into space.
Gravity, mass and centrifugal force all contribute to the final shape of a planet.
Gravity is something every person on Earth intuitively understands: It is what keeps you on the ground. But how come gravity pulls down, rather than pushes up? Einstein came up with the answer.
The reason bigger objects in space are round and smaller ones aren’t boils down to gravity. And it’s the same reason mountains on Earth can only grow to a certain height
The English astronomer and navigator Thomas Harriot died in 1621, leaving behind 8,000 pages of notes containing a trove of unpublished scientific discoveries.
Gravitational waves reveal the demise of super-dense neutron stars spiralling into their black hole companions - the first time such strange and exotic star systems have ever been observed.
The world’s biggest gravitational wave observatory is now probing the limits of quantum mechanics.
Sea level is still rising, and when that lunar cycle starts upward again, it will mean double trouble for places like Miami.
A young reader asks: What is the sky?
Going to the bathroom is much more complicated in space without any gravity. To solve this problem of tricky orbital potty breaks, NASA builds special toilets that work without gravity.
If you are a sci-fi junkie you’ve probably wondered what would happen if you were unlucky enough to fall into a black hole. How well you’d fare all depends on the type of black hole.
Bubbles sinking, oceans levitating… It may seem straight out of science fiction, but it can be done in a laboratory.
The Earth spins around its axis every day – but gravity keeps us firmly in place.
The 2020 Nobel Prize in physics was awarded to three scientists – an Englishman, an American and a German – for breakthroughs in understanding the most mysterious objects in the universe: black holes.
There is a reason why it’s easier to roll marbles down rather than up a hill. And the answer (to this and to gravity itself) is all about acceleration.
If gravity was half as strong, you could jump much higher.
How do people in a special airplane flight get to float like there is no gravity – just like astronauts? An aerospace engineer explains.
Martian meteorites allow scientists here on Earth to decode that planet’s geology, more than a decade before the first missions are scheduled to bring rocks back home from Mars.
The distance between the ISS and Earth is the same as about 3,850 football fields. To bring the station down, rockets will lower it a bit, and then gravity will send it crashing the rest of the way.
Researchers have made some of the most accurate clocks imaginable in recent years, but the trick is harnessing those clocks to electronics. Using lasers to tune microwaves bridges the gap.
