Earth is not only orbiting the Sun it is also traveling through the Milky Way on an enormous galactic journey. In this video we reveal how the Sun carries the entire solar system around the center of ...

NASA's DART mission, which tested a planetary defense strategy, successfully changed the orbit of the asteroid Dimorphos in 2022. The mission also unexpectedly altered the orbit of Dimorphos's larger ...

The standard story of the origin of our solar system has gone like this: 4.6 billion years ago, a giant cloud of dust hung frozen in space. Then the explosion of a nearby star caused part of that dust ...

An exoplanetary system about 116 light-years from Earth could flip the script on how planets form, according to researchers who discovered it using telescopes from NASA and the European Space Agency, ...

Space-based solar power represents a transformative shift in renewable energy, capturing sunlight in orbit and transmitting electricity to Earth continuously. Orbiting photovoltaic arrays receive ...

Another day, another ambitious company emerges to harness the power of the Sun from Earth's orbit. Okay, it's not quite that common an occurrence, but there are indeed a number of firms giving this a ...

New measurements of radio galaxies reveal that the solar system is racing through the universe at over three times the speed predicted by standard cosmology. Using highly sensitive data from multiple ...

How fast and in which direction is our solar system moving through the universe? This seemingly simple question is one of the key tests of our cosmological understanding. A research team led by ...

Voyager 1, launched in 1977, has traveled farther than any spacecraft in human history. After more than four decades of silent endurance through space, it now sails beyond the orbit of the outer ...
