International astronomers have for the first time witnessed the birth of a planetary system beyond Earth's sun that could one ...

Ever since Isaac Newton famously talked about gravity, its dominance as a force in our solar system has been well known. It's responsible for the orbits of the planets and their satellites, but ...

Cyril Dupuy, the founder of smart telescope maker Vaonis, has set a new record by capturing Europe's highest-altitude image ...

Time, as we experience it on Earth, may not be as constant as we imagine. According to Einstein’s theory of general relativity, time is not uniform across the universe; it’s actually affected by both ...

Low-mass stars like our Sun expel their outer layers as a planetary nebula because of what is going on in the star’s core as ...

News; Sci/Tech; Ask Dr. Universe: Gravity is a big reason why the sun is so hot Mon., Sept. 2, 2024 Things can be solid, liquid or gas. The sun, however, is plasma. That’s a fourth state of matter.

Gravity is the force of action between two objects. ... Gravity is the force that holds us down on Earth and what keeps the planets spinning around the Sun. 09/01/2024 | Rating TV-G.

The sun has lots of gravity because it’s ginormous compared to Earth. So, that gravity pulls on the Earth and holds us in orbit. But our sun isn’t the only star.

Apparently, a “portal” opens every eight minutes or so between Earth and the sun, and particles streaming through it move ultra-quickly between the planet and its star.

The near-pass, which will see the probe fly through plumes of plasma spewing off the Sun at a record 430,000 miles per hour (692,000km/hr), is the probe’s final objective.

In order to beat the old record, this time the probe flew just 4.51 million miles away from the sun. This was all set up by a gravity-assist flyby of Venus. To do so, ...
