New research from the University of St Andrews has proposed that particles in solar flares are 6.5 times hotter than previously thought. The research provides an unexpected solution to a 50-year-old mystery about our nearest star.

Solar flares are sudden and huge releases of energy in the sun’s outer atmosphere that heat parts of it to greater than 10 million degrees. These dramatic events greatly increase the solar X-rays and radiation reaching Earth and are hazardous to spacecraft and astronauts, as well as affecting our planet’s upper atmosphere.

The research, published in The Astrophysical Journal Letters, looks at evidence of how flares heat solar plasma to greater than 10 million degrees. This solar plasma is made up of ions and electrons...

Saturn’s moon Titan may be more alive with possibilities than we thought. New NASA research suggests that in Titan’s freezing methane and ethane lakes, simple molecules could naturally arrange themselves into vesicles—tiny bubble-like structures that mimic the first steps toward life. These compartments, born from splashing droplets and complex chemistry in Titan’s atmosphere, could act like primitive cell walls.

NASA research has shown that cell-like compartments called vesicles could form naturally in the lakes of Saturn’s moon Titan.

Titan is the only world apart from Earth that is known to have liquid on its surface...

What can the galactic habitable zone (GHZ), galactic regions where complex life is hypothesized to be able to evolve, teach scientists about finding the correct stars that could have habitable planets?

This is what a recent study accepted for publication in Astronomy & Astrophysics hopes to address as an international team of researchers investigated a connection between the migration of stars, commonly called stellar migration, and what this could mean for finding habitable planets within our galaxy...

A study led by Jenny Frediani at Stockholm University has revealed a planet-forming disk with a strikingly unusual chemical composition: an unexpectedly high abundance of carbon dioxide (CO2) in regions where Earth-like planets may one day form.

The discovery, made using the James Webb Space Telescope (JWST), challenges long-standing assumptions about th...
