Einstein's theory of gravity, also referred to as General Relativity, predicts that a rotating body such as the Earth partially drags inertial frames along with its rotation. In a study recently published in EPJ Plus, a group ...
While one of the most important challenges for future interstellar travel is to how send a probe to another stellar system relatively quickly, another issue that needs to be resolved is how to successfully slow down such ...
Astronomers are reporting a rare star as big—or bigger—than the Earth's sun that is expanding and contracting in a unique pattern in three different directions.
In April last year, billionaire Yuri Milner announced the Breakthrough Starshot Initiative. He plans to invest 100 million US dollars in the development of an ultra-light light sail that can be accelerated to 20 percent of ...
What could be better than a world-leading atomic clock? Two clocks in one.
Planets develop from the dusty placental disk of material that surrounds a star after it begins to shine. The dust in that disk, according to most models, starts to stick to itself until clumps develop large enough to attract ...
The European Space Agency's orbiting X-ray observatory, XMM-Newton, has proved the existence of a "gravitational vortex" around a black hole. The discovery, aided by NASA's Nuclear Spectroscopic Telescope Array (NuSTAR) mission, ...
On July 4, the veil over Jupiter's mysteries will be ripped away with the arrival of NASA's Juno mission, and Jonathan Lunine will be there to watch it happen.
Now that scientists have confirmed the existence of gravitational waves, a NASA team is set to search for a predicted signature of primordial gravitational waves that would prove the infant universe expanded far faster than ...
(Phys.org)—HAT-P-26b is an inflated, Neptune-mass exoplanet located about 437 light years from Earth, which orbits its parent star HAT-P-26 every 4.23 days. The planet has a relatively low surface gravity that is well suited ...
