... The secret messages are calling to me endlessly They call to me across the air The messages across the atmosphere They whisper in your ear, they call me everywhere Where words cascade like rainbows Tumbling from the sky Then I'll be there, I'll be there When messages will call to you Their secrets all around Without a sound, they're all around The secret messages are calling to me endlessly They call to me across the air The ...

... WFPC2 , HST , NASA Explanation: Planetary nebulae are strange. ... But now yet another mystery has come to light: what created the fast-moving gas clouds that appear around planetary nebula ? Dubbed FLIERs for Fast Low-Ionization Emission Regions, these knots of dense gas appear to have been ejected from the central star before it cast of the planetary nebula. ... In the above false-color picture of NGC 7662, the Blue Snowball Planetary Nebula , the FLIERs are featured in the image inserts. ...

... Bringing news from across the Universe to children all around the world . ... This beautiful new photograph from one of the European Southern Observatory s powerful telescopes in the Chilean desert shows a pair of galaxies slowly dancing around each other in space. Like many things in nature, the large, glowing galaxy in the picture is beautiful, but dangerous. ... Cool Fact . As a bonus, this new picture also provides a window into the distant Universe, far beyond the interacting galaxies. ...

... I used Crowley and dropped my car off in Jacksonville. ... They asked me for my driverґs license, social security card and car title. ... I handed them: the $10 stamp, car title, most recent stateside registration certificate, driver's license, social security card, ACAA receipt, import tax receipt, and vehicle inspection certificate. ... I did, and by that time, everything was finally ready and I walked out the door with my Puerto Rico car title, new license plate and sticker. ...

... Today this year's largest group of sunspots will cross the Sun's central meridian. ... The next day, the number of spots in the group reached five, and the day after, on June 2nd, it was possible to count thirteen sunspots on solar disk, which had been clear prior to this. ... This year's two most powerful active areas, which passed across the solar disk at the beginning of May, 2009, are set to appear in the Sun's eastern sector in two days, on June 6th. ...

The apparent path of the Sun across the sky. ... The path of the Sun across the celestial sphere is very close to that of the planets and the moon. ... In one year, as the Earth completes a full circuit around the Sun (drawing above), the Earth-Sun line and its continuation past Earth sweep the entire plane. ... Since the Sun and Earth are in the plane of the ecliptic, the line is automatically in that plane too; if the moon is also on the same line, it must be in the plane of the ecliptic as well. ...

... 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. ...

A critical step is the growth of small dust particles from the submicron sizes of interstellar medium to pebbles and kilometer-sized bodies. ... The analysis of the radial profi les of the fl ux density at 850 ЮМm also reveals an excess emission near the location of the CO snowline at 90 AU (see Figure 1): this feature could indicate a local change in the dust properties . ...

The ntpq and xntpdc utility programs can be used to debug reference clocks, either on the server itself or from another machine elsewhere in the network. The server is compiled, installed and started using the command-line switches described in the xntpd page. ... First, use the pe and as commands to display billboards showing the peer configuration and association IDs for all peers, including the radio clock peers. ... The most useful are the clockstat and commands described in the document page. ...

... The Sun . Does anyone know how many stars are there in the solar system? Come take a look at the Sun. See that? ... Did you know all the stars you see when you look up are inside our galaxy! ... Did you know that our Sun and solar system were born in a cloud of gas and dust like this. ... We're looking at a place where stars are being born. ... Sharing the Universe is based upon work supported by the Informal Education Division of the National Science Foundation under Grant no DRL-0638873. ...

. The maps show thermal infrared radiation (heat) coming from Titan's surface at a wavelength of 19 microns, a spectral window at which the moon's otherwise opaque atmosphere is mostly transparent. Temperatures have been averaged around the globe from east to west (longitudinally) to emphasize the seasonal variation across latitudes (from north to south). Black regions in the maps are areas for which there was no data. NASA/JPL-Caltech/GSFC

... We present a comparison of the surface density of young stars (неБ‹†) and dust surface density (неdust) across NGC 346 (N66) in 115 independent pixels of 6 ц— 6 pc2. ... We convert неdust to gas surface density (неgas) and неБ‹† to star formation rate (SFR) surface densities (неSFR), using simple assumptions for the gas-to-dust mass ratio and the duration of star formation. ... On small scales the неSFR derived using Hн± systematically underestimates the count-based неSFR, by up to a factor of 10. ...

... Solar System . ... Sun . ... Comets . ... Some get thrown out of the solar system forever, whereas others end up on yet smaller orbits, visiting the inner solar system fairly frequently - such as comet Halley. ... When a comet moves into the inner solar system, this is heated by the Sun, and the ices turn into gas which forms the head or coma of the comet, which may be hundreds of thousands of kilometres across and visible from Earth. The most striking part of many active comets is the tail . ...

... 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. ...

... SATELLITE: An object that revolves around a planet. ... SIDEREAL DAY: The length of a planet's rotation period relative to the stars. SOLAR SYSTEM: The sun and all the objects that are held in its gravitational field and move around it. ... SUPERIOR CONJUNCTION: The position of a planet when it is on the opposite side of the Sun from Earth (thus making in invisible). ... TRANSIT: The movement of an object between the Earth and the Sun and showing on the surface of the sun as a black dot. ...

... We have measured this "redshift" for the pink black holes, and allowed for it in our calculations. ... We see this effect in the emission from gas around these pink black holes, but it is far too small an effect to account for the pinkness. Thus the swirling motions of gas around or into the black holes cannot produc the colour. ... At first we thought that these things were normal blue black holes hidden behind clouds of interstellar dust, that absorbed the blue light and made them appear pink. ...

Information about this camera is below . ... You probably got here from the server push version of the web page, which is the "default". ... I can't remember if my inspiration was that someone else put a camera on the web, or that someone else had a camera on the Mbone in their office. ... I actually put two cameras on the web at the same time (because we had two), one in my office, which I pointed out of the window, and one in Frank's office. ... Previous . ...
