Aspacecraft launched by NASA has done what was once thought impossible. On April 28, the Parker Solar Probe successfully entered the corona of the sun — an extreme environment that’s roughly 2 million...
One of Life’s Building Blocks Found around Infant Sun-like Stars
Life’s Building Blocks Infant Sun-like Stars
2017/7/21
Our solar system is teeming with simple carbon-based molecules, the basic building blocks of life. If the conditions are right, these simple molecules can go on to form more complex, biologically inte...
The same kind of large-scale planetary waves that meander through the atmosphere high above Earth's surface may also exist on the Sun, according to a new study led by a scientist at the National Cente...

Analyzing sun-like stars eat Earth-like planets
2014/6/12
Some Sun-like stars are ‘Earth-eaters.’ During their development they ingest large amounts of the rocky material from which ‘terrestrial’ planets like Earth, Mars and Venus are made.
New findings from NASA's Solar Dynamics Observatory (SDO) reveal that the Sun's surface is an even more complicated web of physical and magnetic processes than previously thought. The finding was unve...
Physicists have so far failed to find direct evidence for the existence of dark matter – the non-luminous substance believed to make up some 23% of the mass-energy content of the universe – at least t...

The Sun's magnetic field environment astronauts
2010/9/21
The Sun's extended magnetic field provides a vital shield for astronauts; without it they would be left exposed to potentially deadly cosmic rays entering in from outside the solar system. Now, a grou...
The first high-resolution images of the Sun have been returned from NASA's Solar Dynamics Observatory (SDO), which was launched in February. The $850m mission will investigate the causes of solar vari...
After more than five decades of research, a major milestone toward the harnessing of fusion power is expected within the next year or two. This milestone, known as “fusion ignition,” should take place...

2009/9/28
Researchers in the US may have discovered further evidence that the Sun is heading towards an extended period of quiet activity, the like of which has not been seen since the 17th century. The impact ...
The unusually long quiet period of the Sun’s present activity may be due to the motion of “sluggish” jet streams beneath the solar surface, according to scientists at the National Solar Observatory (N...
