Researchers study fluctuations in solar radiation

The Sun is the Earth's principal source of energy and climate driver. Yet sometimes it sends more light to the Earth than other times. Astronomers working with Natalie Krivova at the Max Planck Institute for Solar System ...

Techniques to prove or disprove existence of other planets

Astronomers long have sought to find planets that can sustain life as humans know it. Four years ago, they thought they had one, possibly even two, pointing to signs that suggested that at least one rocky planet located in ...

What is Mars made of?

For thousands of years, human beings have stared up at the sky and wondered about the Red Planet. Easily seen from Earth with the naked eye, ancient astronomers have charted its course across the heavens with regularity. ...

The two faces of Mars

A moon-sized celestial object that crashed into the south pole: ETH researchers use a simulation to demonstrate why Mars consists of two notably different hemispheres.

Suddenly, the sun is eerily quiet: Where did the sunspots go?

The sun has gone quiet. Almost too quiet. A few weeks ago it was teeming with sunspots, as you would expect since we are supposed to be in the middle of solar maximum-the time in the sun's 11-year cycle when it is the most ...

Discovering a hidden source of solar surges

Cutting-edge observations with the 1.6-meter telescope at Big Bear Solar Observatory (BBSO) in California have taken research into the structure and activity of the Sun to new levels of understanding. Operated by New Jersey ...

SDO mission untangles motion inside the Sun

(Phys.org) —Using an instrument on NASA's Solar Dynamics Observatory, called the Helioseismic and Magnetic Imager, or HMI, scientists have overturned previous notions of how the sun's writhing insides move from equator ...

Researchers reveal model of Sun's magnetic field

Researchers at the Universities of Leeds and Chicago have uncovered an important mechanism behind the generation of astrophysical magnetic fields such as that of the Sun.
