Latest Astronomical objects Stories
Astronomers are reaching out to the public and asking for a little help in a study to find holes in dust clouds.
The European Space Agency (ESA) said its Herschel space observatory found a gas and dust cloud that contains enough water vapor to fill Earth's oceans more than 2,000 times over.
One star pinpointed as a prime location for a planet-forming disk decided enough was enough, and closed-up shop suddenly.
After several decades of making a lonely journey across our solar system, Voyager 1 has signaled to NASA that it may have reached the edge of interstellar space.
Japanese researchers discovered while studying grains of dust from the Itokawa asteroid that tiny particles of space dust bombard asteroids and give them their shape.
A new image from the APEX (Atacama Pathfinder Experiment) telescope in Chile shows a sinuous filament of cosmic dust more than ten light-years long. In it, newborn stars are hidden, and dense clouds of gas are on the verge of collapsing to form yet more stars.
Researchers announced the finding at a press conference on Jan. 31, 2012. It’s based on data from NASA’s IBEX spacecraft, which is able to sample material flowing into the solar system from interstellar space.
Researchers, uding NASA's Interstellar Boundary Explorer (IBEX) spacecraft, have measured neutral "alien" particles that have entered our solar system from interstellar space.
Scientists within the New York Center for Astrobiology at Rensselaer Polytechnic Institute have compiled years of research to help locate areas in outer space that have extreme potential for complex organic molecule formation.
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...
