NASA’s New Horizons probe, which hurtled past Pluto in 2015, demonstrates that it can sail through interstellar space using ...

A giant gas planet comparable in size to Saturn exists around a small red dwarf star. The discovery is beyond the scope of conventional astronomy theory, and is making experts reconsider conventional ...

Stars often whip their planets with solar winds and radiation, pull them ever closer with gravity and sear them with heat.

They happen when massive stars – much bigger than our Sun – go too close to a supermassive black hole and are torn to pieces. The resulting collision throws out vast amounts of energy that ...

While our Sun prefers to go solo, many other stars are parts of binary systems, with a pair of stars gravitationally bound to each other. In some cases, the stars are far enough apart that planets ...

News Science News Astronomers discover giant star-forming cloud, 5,000 times larger than the Sun, near our solar system ...

The crescent-shaped cloud is over 5,000 times heavier than our Sun. Eos is a dense and cold region of gas and dust, typically known for giving birth to stars.

Small Stars and Our Sun The smallest stars — those smaller than our sun, for example — may never get past the hydrogen burning stage. They aren’t quite hot enough to begin fusing heavier elements, so ...

These spots are even larger than the entire surface of our sun — which is why XX Tri has been dubbed "the most spotted star in the sky," Kővári said.

In the vast night sky, where countless stars vie for attention, one colossus reigns supreme as the largest star in the universe. Situated thousands of light-years from Earth, this celestial giant ...

Despite being predicted in theory, the rare cosmic event had never been seen before. It only occurs in enormous stars 60 to 150 times larger than our Sun.

Astronomers have been left baffled after spotting a giant star 'hiccuping'. The rare cosmic event only occurs with exceptionally large stars between 60 to 150 times the mass of the sun (artist's ...
