... Would you say the space between your eyes and your hand is empty? ... This means it s completely empty, without a single particle of gas or speck of dust. ... However, while much of the Universe is a vacuum, there are patches which aren t. These are places where cosmic gas and dust that floats between the stars in a galaxy. ... But ISM material clumps together over time forming larger, heavier blobs of gas and dust until they make a big cloud in space, like the one in this photograph. ...

... High-velocity clouds (HVCs) were discovered by Muller, Oort & Raimond (1963) in the 21-cm line emission of neutral, atomic hydrogen. They are gas clouds which are characterised by high radial velocities incompatible with a participation in the rotation of our Galaxy. ... This suggestion was seized by Braun & Burton (1999) who identified 66 compact high-velocity clouds (CHVCs) with positional and kinematic characteristics being compatible with a distribution across the entire Local Group. ...

But staring toward the northern constellation Bootes on March 19th, even without binoculars or telescope you still could have witnessed a faint, brief, flash of light from a gamma-ray burst . The source of that burst has been discovered to lie over halfway across the Universe at a distance of about 7.5 billion light-years. ... March . ... Publications with keywords: gamma-ray burst .

Various types of stars have dust around them. In the well known case of the Pleiades the dust around the stars is unrelated to the stars, and is instead dust from an interstellar cloud that the Pleiades cluster has drifted into on its way through the galactic disk. ... The dust in interstellar space is observed in a variety of ways: due to its passive absorption of starlight ("extinction"), by its production of polarization in starlight, and then at long wavelengths due to its thermal radiation. ...

... self-absorption - the absorption of light shining on an object by a process similar to that which produced the light originally; if a cloud emits less light than it absorbs from other clouds behind it, this net loss of light, termed self-absorption , causes the foreground cloud to appear darker than the background field (the term is from spectroscopy, where small absorption dips sometimes occur in larger emission lines, making the latter look as if it is absorbing part of itself) . ...

What changed our view of Chariklo is the discovery of a ring system around it, the first such feature found around a Solar System body smaller than a gas giant planet. ...

... Armagh Observatory and award-winning sound artist and musician, Robert Jarvis, are launching the first permanent "aroundNorth" installation at the Observatory on the afternoon of 19 March 2015. "aroundNorth" is a multi-speaker sound composition that gives listeners an inspiring aural experience of the movement of the stars across the night sky, demonstrating the continuous motion of stars in the near Universe around the North Celestial Pole as the Earth rotates on its axis. ...

... STScI-PRC99-13 HUBBLE CLICKS IMAGES OF IO SWEEPING ACROSS JUPITER While hunting for volcanic plumes on Io, NASA's Hubble Space Telescope captured these images of the volatile moon sweeping across the giant face of Jupiter. Only a few weeks before these dramatic images were taken, the orbiting telescope snapped a portrait of one of Io's volcanoes spewing sulfur dioxide "snow." ... Astronomers increased the color contrast and added false colors to the image to make the faint plume visible. ...

... Our Sun is part of a huge wheel-shaped collection of stars. ... Astronomers have long suspected it was a very massive black hole, and that every galaxy had such a central mass, created early in the history of the universe. ... However, unless that object happens to be headed directly at the black hole (a relatively small target) it will just swing around and fly away again, like a comet making a pass at the Sun. The velocity acquired in falling towards the black hole also helps it escape. ...

... This year's eclipse is unique in duration. ... Although, at the present time, there are 6 solar observatories belonging to leading space agencies in orbit around the Earth, the eclipse of 22 July, 2009, will only be seen by two of them: the Russian CORONAS-PHOTON satellite equipped with TESIS telescopes and Japan's HINODE satellite fitted with an XRT space telescope. ... TESIS will be the first of the two devices (and the very first on Earth) to witness the solar eclipse. ...

... What was needed was a complementary instrument consisting of an array of detectors designed to map the clouds using the signals emitted by the molecules in the gas. Such a facility, offering simultaneous spectroscopy and imaging, is currently being commissioned on the JCMT. ... ACSIS was built by the Dominion Radio Astrophysical Observatory in Penticton, Canada, and the UKATC. ... HARP/ACSIS can map molecular gas in molecular clouds throughout the Universe rapidly and with great sensitivity. ...
