太阳 天体物理学 帕克太阳探测器
2023/6/21
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...

AMHERST, Mass. – Using one of the most sensitive neutrino detectors on the planet, an international team of physicists including Andrea Pocar, Laura Cadonati and doctoral student Keith Otis at the Uni...
Constraints on dark matter models from a Fermi LAT search for high-energy cosmic-ray electrons from the Sun
Cosmic Rays Electrons Fermi Sun
2011/10/13
During its first year of data taking, the Large Area Telescope (LAT) onboard the Fermi Gamma-Ray Space Telescope has collected a large sample of high-energy cosmic-ray electrons and positrons (CREs). ...
Enhanced Sensitivity to Dark Matter Self-annihilations in the Sun using Neutrino Spectral Information
Dark Matter, Solar WIMPs, WIMP-nucleon scattering cross section, Neutrino Astronomy
2011/10/10
Self-annihilating dark matter gravitationally captured by the Sun could yield observable neutrino signals at current and next generation neutrino detectors. By exploiting such signals, neutrino detect...
Mass Loss, Destruction and Detection of Sun-grazing and -impacting Cometary Nuclei
comet sun impact sun-grazing radiation collisions
2011/9/30
Incoming sun-grazing comets almost never re-emerge, but no final destruction event has ever been observed, nor sun-impactor destruction theory developed. We seek analytic models of comet nucleus destr...
Measuring the Earth-Sun distance during a lunar eclipse
Measuring Earth-Sun distance lunar eclipse
2011/9/28
The classical method for measure the Earth-Sun distance is due to Aristarchus and it is based upon the measure of the angle Moon-Earth-Sun when the Moon is exactly in quadrature. Such an angle is only...
Physics of the Sun’s Hot Atmosphere
Solar atmosphere X-ray EUV emission coronal heating solar wind
2010/9/16
This article briefly overviews the physics of the Sun’s hot atmosphere,using observations from recent solar spacecrafts: Yohkoh, SOHO,TRACE and RHESSI.
Why Study the Sun?
Sun—flares—prominences—coronal mass ejection—coronal holes—helioseismology
2010/9/16
In this presentation we briefly describe the Sun through large number of illustrations and pictures of the Sun taken from early times to the present day space missions. The importance of the study of ...
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...

'Self-repairing' photovoltaics the Sun
2010/9/21
Researchers at the Massachusetts Institute of Technology have fabricated the first synthetic photovoltaic cell capable of repairing itself. The cell mimics the self-repair system naturally found in pl...

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...
