The region in space around a planetary nebula is filled with harsh radiation. Yet despite this hostile environment, the area is seeded with a molecule essential to the formation of water.
A team of scientists at NASA's Ames Research Center has successfully reproduced, right here on Earth, the processes that occur in the atmosphere of a red giant star and lead to the formation of planet-forming interstellar dust.
Our Galaxy's magnetic field is revealed in a new image from ESA's Planck satellite. This image was compiled from the first all-sky observations of 'polarised' light emitted by interstellar dust in the Milky Way.
Scientists have long delved into the mysteries of the origins of life here on Earth and more recently have found evidence pointing to the skies above us. Some evidence has been found in material created in space and delivered to Earth via comets and meteors, containing the building blocks for life.
Dust that originates from comets, asteroids and leftover debris from the birth of the Solar System could deliver water and organic material to the Earth and other terrestrial planets, according to a recent Proceedings of the National Academy of Science paper.
A new image of a recent supernova could offer up insight to scientists about how galaxies became so dusty.
Vito Technology has announced the release of their award-winning astronomy guide Star Walk for Android.
Interstellar magnetic fields can be found throughout the Milky Way and other similar galaxies. They are thought to be a key regulator in star formation and the propagation of cosmic rays.
USRA-led team finds polarized starlight implicates interstellar dust as host of hydrogen molecule formation, allows tracing magnetic fields in space. Columbia,
Astronomers using the Mopra Telescope in Coonabarabran, Australia have begun mapping the location where stars are born.
Interstellar Cloud -- Interstellar cloud is the generic name given to accumulations of gas and dust in our galaxy. Depending on the density, size and temperature of a given cloud, the hydrogen in it can be neutral (HI clouds) or molecular (molecular clouds). Chemical compositions Analysing the composition of interstellar clouds is achieved by studying electromagnetic radiation that we receive from them. Large radio telescopes scan the intensity in the sky of particular frequencies of...
Solar Wind -- Solar wind, a stream of particles (mostly high-energy protons ~ 500 Kev) that is continually ejected from the surface of the Sun. The composition of this plasma is identical to the Sun's corona, 73% hydrogen and 25% helium with the remainder as trace impurities, and is ionized. Near Earth, the velocity of the solar wind varies from 200km/s-889km/s. The average is 450 km/s. Approximately 3000 tons of material is lost from the Sun every hour as solar wind. Since solar...
