While much of the research around the eclipse on Monday will focus on the effects of the Sun's brief, daytime disappearance on Earth and its atmosphere, a group of solar physicists will be leveraging the rare event to capture a better glimpse of the star itself.
A University of Oklahoma astrophysicist, Mukremin Kilic, and his team have discovered two detached, eclipsing double white dwarf binaries with orbital periods of 40 and 46 minutes, respectively. White dwarfs are the remnants of Sun-like stars, many of which are found in pairs, or binaries.
Researchers from Predictive Science Inc. used NASA and National Science Foundation-supported supercomputers to run highly-detailed forecasts of the Sun's corona -- the aura of plasma that surrounds the sun -- at the moment of the eclipse. The team combined data from NASA's Solar Dynamics Observatory, magnetic field maps, solar rotation rates and cutting-edge mathematical models to predict the state of the Sun's surface. The simulations are the largest produced by the group and include new physics.
A research team from Predictive Science Inc. (PSI) used the Stampede2 supercomputer at The University of Texas at Austin's Texas Advanced Computing Center (TACC) to forecast the corona of the sun during the upcoming eclipse. The findings shed light on what the eclipse of the sun might look like Aug. 21 when it will be visible across much of the US, tracing a 70-mile-wide band across 14 states.
Using seven spacecraft, along with computer models, scientists have pieced together the journey of a coronal mass ejection from the Sun outward to Mars, Comet 67P, Jupiter and even the New Horizons spacecraft now beyond Pluto.
Ten spacecraft, from ESA's Venus Express to NASA's Voyager-2, felt the effect of a solar eruption as it washed through the solar system while three other satellites watched, providing a unique perspective on this space weather event.
If the weather is good, viewers across the UK will be treated to a partial solar eclipse on Aug. 21, 2017, just before sunset. In a partial eclipse, a small bite out of the sun can be seen at the mid-eclipse point, as it is covered by the moon.
Many exoplanets to be found by coming high-powered telescopes will probably be tidally locked -- with one side permanently facing their host star -- according to new research by astronomer Rory Barnes of the University of Washington.
Thanks to a global network of telescopes, astronomers have caught the fleeting explosion of a Type Ia supernova in unprecedented detail. Because this type of supernova is commonly used as a cosmic yardstick, a better understanding of how they form could have implications for future dark energy measurements.
In the 2009 film 'Star Trek,' a supernova hurtles through space and obliterates a planet unfortunate enough to be in its path. Fiction, of course, but it turns out the notion is not so farfetched.
