The total solar eclipse of 21 August 2017 traversed 5,000 km from coast to coast of North America. In its 90-min span, sunlight dropped by three orders...
NASA’s Voyager 2 spacecraft has detected an increase in cosmic rays that originate outside the Solar System. Currently, the probe is approximately 11...
An international team of researchers led by RMIT University has developed paper-based UV sensors that could help people manage vitamin absorption and avoid...
Our Sun rotates faster at its equator than at its poles. This process is known as differential rotation and is seen in the motion of sunspots. Now, a team...
Energy generation by wind and solar farms could reduce carbon emissions and thus mitigate anthropogenic climate change. A new climate-modeling study, published...
Have Carl Sagan and astrobiologists been too hard on stellar flares? A new study imagines an alternative scenario where they power photosynthesis around...
A close flyby of a Sun-mass star several billion years ago could explain some unusual features observed in the outer Solar System.
An artist’s concept...
NASA’s Parker Solar Probe launched yesterday (August 12) from Space Launch Complex-37 at Cape Canaveral Air Force Station in Florida, rising off the...
By examining microscopic ice-blue crystals of mineral hibonite trapped inside a carbonaceous chondrite meteorite, an international team of scientists was...
Data from the NASA/ESA Solar and Heliospheric Observatory (SOHO) have captured the dynamic movement of the Sun’s atmosphere for over two decades. Now,...
NASA’s MAVEN (Mars Atmosphere and Volatile Evolution) spacecraft has found a new type of Martian aurora that occurs over much of the day side of the...
2015 BZ509, an object in Jupiter’s co-orbital region with a retrograde motion around the Sun, is the first known asteroid to have been captured from...
Earth is surrounded by a protective magnetic environment, the magnetosphere, which deflects a supersonic stream of charged particles from the Sun, known...
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...
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,...
