Direction Change For Interstellar Winds
2013-09-06 04:15:08

redOrbit Staff & Wire Reports - Your Universe Online Data obtained through NASA's Interstellar Boundary Explorer (IBEX) project has revealed that neutral interstellar atoms are flowing into the solar system from a different direction than previously observed. That information has led scientists affiliated with the mission to believe that those particles, which flow past the Earth as the solar system passes through the surrounding interstellar cloud at speeds of 23 kilometers per...

How Fast Does A Supernova Shockwave Travel? A Japan Team May Have The Answer
2013-08-13 14:51:55

Brett Smith for redOrbit.com - Your Universe Online Some of the most spectacular explosions this side of the Big Bang, supernovae generate unthinkable amounts of force and energy and new research from Keio University in Japan has measured the expansion velocity of a supernova shockwave for the first time. The shockwave measured by the research team was from the supernova remnant W44, which is located approximately 10,000 light years from Earth. Quantifying the expansion and kinetic...

Furthermore, the mounting of Starship Congress comes about in order to discuss a matter of astronomical importance: the...

More Galactic Gas In Milky Way Than We Thought
2013-06-11 14:31:02

Brett Smith for redOrbit.com - Your Universe Online The building blocks of stars, clouds of molecular gases, are strewn across the Milky Way, and a new survey from the European Space Agency (ESA) and NASA has found that scientists have been underestimating the amount of gas in the galaxy by about one-third. According to a new report in journal Astronomy and Astrophysics, the discovery was made possible by the orbiting Hershel Space Observatory, a joint venture between the two space...

Airborne Observatory Reveals Mystery Of Star Formation
2013-04-17 11:52:24

Brett Smith for redOrbit.com - Your Universe Online Using observations from an airborne observatory, NASA researchers have discovered new details on how massive stars form within a cloud of interstellar gas and dust. An emerging star known as G35 has been observed forming in an orderly process similar to the one undergone by smaller stars like our sun, according to the scientists´ report in the Astrophysical Journal. Lead author Yichen Zhang said the observations of G35 made...

Astronomers Spot 'Soccer Ball' Molecules In Space
2013-03-05 13:10:23

Lee Rannals for redOrbit.com - Your Universe Online An international team of astronomers are reporting in The Astrophysical Journal they have spotted what resembles a soccer ball sitting in the dying star M1-11. Five instruments helped astronomers detect C60 fluorine in the dying star, which are molecules of carbon with 60 atoms arranged in patterns that resemble a soccer ball. Astronomers used the Subaru Telescope, the Spitzer Space Telescope (SST), ESO's Very Large Telescope, the...

Icy Cosmic Start For Amino Acids And DNA Ingredients Suggested By New Discoveries

National Radio Astronomy Observatory [ Watch the Video Answering Questions Of Where Prebiotic Molecules Form ] Using new technology at the telescope and in laboratories, researchers have discovered an important pair of prebiotic molecules in interstellar space. The discoveries indicate that some basic chemicals that are key steps on the way to life may have formed on dusty ice grains floating between the stars. The scientists used the National Science Foundation's Green Bank...

Supernova Gives Scientists Clues Into Origins Of Cosmic Rays
2013-02-14 13:19:29

[ Watch the Video: Fermi Proves Supernova Remnants Produce Cosmic Rays ] Lee Rannals for redOrbit.com - Your Universe Online A thousand-year-old supernova has given the European Space Observatory's Very Large Telescope (VLT) ample opportunity to gain some clues about the origins of cosmic rays. The new observations, reported in the journal Science today, suggest the presence of fast-moving particles in the supernova remnant. Over a thousand years ago, in 1006 AD, a new star was...

New Theory Of ENAs At Edge Of Solar System Checks Out With Data
2013-02-06 11:58:06

John P. Millis, Ph.D. for redOrbit.com — Your Universe Online While our solar system contains many fascinating objects — planets, moons and the Sun, to name just a few — one of the most interesting and perplexing of these objects lies at its very edge. Our Sun sweeps charged particles through the solar system, encasing us in a cocoon that shields us from the interstellar environment. It is at the boundary of the solar system, where the solar wind slows and the...

Scientists Deduce Contents Of Cosmic Mystery Box
2013-01-01 10:16:02

April Flowers for redOrbit.com - Your Universe Online Science teachers in grade school sometimes hand out "mystery boxes," which contain ramps, barriers and a loose marble. Rotating the marble and feeling it hang up or drop, the students begin to deduce the contents of the box. Scientists who are trying to understand why tiny particles rain down from space face a similar dilemma, but on a much grander scale. Their mystery box is a hundred thousand light years across, and the only clues...

UV Astronomy -- UV astronomy is the branch of astronomy and astrophysics which deals with objects visible in ultraviolet (UV) radiation. UV radiation ranges approximatively from 10nm (extreme UV) to 380nm (near UV). Ultraviolet line spectrum measurements are used to discern the chemical composition, densities, and temperatures of interstellar medium, and the temperature and composition of hot young stars. UV observations can also provide essential information about the evolution of...

Molecular Cloud -- Molecular clouds are interstellar nebulae that have a density and size sufficient to permit the formation of H2, molecular hydrogen. However, this molecule is difficult to detect, and the molecule most used to trace the H2 is CO (carbon monoxide). The ratio between CO luminosity and H2 mass is roughly constant, although there are reasons to doubt this assumption in observations of some other galaxies. In the Milky Way, molecular clouds account for roughly one-half...

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...

Heliopause -- The heliopause is the boundary where our Sun's solar wind is stopped by the interstellar medium. The solar wind blows a "bubble" in the interstellar medium (the rareified hydrogen and helium gas that permeates the galaxy). The point where the solar wind's strength is no longer great enough to push back the interstellar medium is known as the heliopause, and is often considered to be the outer "border" of the solar system. The distance to the heliopause is not precisely...

Emission Nebula -- In astronomy, emission nebulae are clouds of ionized gas, emitting light of various colors. The most common source for ionization are high-energy photons emitted from a nearby young, hot star. Usually, a young star will ionize part of the same cloud from which it was born. Only big, hot stars can release the amount of energy required to ionize a significant part of a cloud. Often, an entire cluster of young stars is doing the work. The nebula's color depends on...
