Planetary nebulae — massive rings of luminous, interstellar gas and dust — mark the end of the active life of 90% of all stars. But, for years,...

A research team led by Rutgers University’s Professor Dennis Kent has documented a gradual shift in Earth’s orbit that repeats regularly every 405,000...

A new study indicates that solar tornadoes may have been misnamed because scientists have so far only been able to observe them using 2D images. Composite...

Pioneering new research from the University of Exeter, UK, has revealed when the 11-year solar cycle is in its ‘weaker’ phase, there are warm spells...

About 70,000 years ago, a binary stellar system called ‘Scholz’s star’ passed within only 52,000 astronomical units (AU) of the Sun, i.e., within...

The long-standing mystery of why comets give off X-ray emission has been solved by a group of experimental physicists led by the University of Oxford,...

The NASA/ESA Solar and Heliospheric Observatory (SOHO) and NASA’s Solar and Terrestrial Relations Observatory (STEREO) have captured amazing photos of...

High-energy X-ray emissions at Jupiter’s south pole consistently pulse every 11 minutes; meanwhile those at the gas giant’s north pole are erratic:...

In a paper published on October 1 in the journal Astronomy & Geophysics, independent scholar and astrophysicist Graeme Waddington and University of...

For the first time, astronomers think they’ve spotted an asteroid (or perhaps a comet) in the Solar System that came from interstellar space. A/2017...

According to new research using data from NASA’s Mars Atmosphere and Volatile Evolution Mission (MAVEN) spacecraft, the Red Planet has an invisible magnetic...

A new study published in the journal Advances in Space Research suggests that solar storms create a complex electrical environment around Phobos, giving...
