Hinode, IRIS, and ATERUI cooperate on 70 year old solar mystery

Solar physicists have captured the first direct observational signatures of resonant absorption, thought to play an important role in solving the "coronal heating problem" which has defied explanation for over 70 years.

Next solar maximum may be safest time for manned missions to Mars

Humans have long dreamed of traveling to Mars, and several nations and private organizations are developing plans for crewed Mars missions in the coming decades. But a recent study looking at the risks for astronauts going ...

Sun may determine lifespan at birth, study finds

Could the Sun be your lucky—or unlucky—star? In an unusual study published Wednesday, Norwegian scientists said people born during periods of solar calm may live longer, as much as five years on average, than those who ...

Sun's activity influences natural climate change

For the first time, a research team has been able to reconstruct the solar activity at the end of the last ice age, around 20,000-10,000 years ago, by analysing trace elements in ice cores in Greenland and cave formations ...

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 ...

Sun continues to emit solar flares

After emitting its first significant solar flares since June 2013 earlier in the week, the sun continued to produce mid-level and significant solar flares on Oct. 27 and Oct. 28, 2013.

The sun also flips: 11-year solar cycle wimpy, but peaking

(Phys.org) —In a 3-meter diameter hollow aluminum sphere, Cary Forest, a UW-Madison physics professor, is stirring and heating plasmas to 500,000 degrees Fahrenheit to experimentally mimic the magnetic field-inducing cosmic ...

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 ...

Coronal mass ejection to pass Earth, Messenger and Juno

On July 16, 2013, at 12:09 a.m. EDT, the sun erupted with an Earth-directed coronal mass ejection or CME, a solar phenomenon that can send billions of tons of particles into space that can reach Earth one to three days later. ...
