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...
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...

Astronomers with the National Science Foundation (NSF)-funded National Optical Astronomy Observatory (NOAO) captured pictures not only of Thursday's partial solar eclipse, but also of the "monster" si...

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...
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). ...
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...
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...
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...
This article briefly overviews the physics of the Sun’s hot atmosphere,using observations from recent solar spacecrafts: Yohkoh, SOHO,TRACE and RHESSI.
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...
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 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...
