A team of U.S. and German astrophysicists have made the first ever detection of X-rays coming from a comet. ... Following the initial detection, the team reported repeated X-ray emissions from the comet over the next 24 hours. ... One preliminary theory is that X-ray emission from the Sun was absorbed by a cloud of gaseous water molecules surrounding the nucleus of the comet, and then were re-emitted by the molecules in a process physicists call "fluorescence." ...

... To run the <LAYER> version of the example, select: flower.htm . ... However, if the page had several layers with absolute positions, and you wanted to place another layer in a relative position to one of the existing layers, you could use inline JavaScript to calculate the value for LEFT or TOP . ... In this example, there is really no need to use inline JavaScript to position the last flower layer, since you could just let the TOP value default to its natural value, as in the other flower layers. ...

For another, the sky near the black hole would appear significantly distorted , with more and more images of the entire sky visible increasingly near the black hole. ... Orbiting a black hole, as shown in the above scientifically-accurate computer-created illustrative video, will show stars that pass nearly directly behind the black hole as zipping around rapidly near the Einstein ring. ...

... Planets . ... Stars . Exoplanets . ... Most exoplanets so far discovered fall into the category of тАШhot JupitersтАЩ, these are giant planets orbiting very close to their parent star. ... Note that we have discovered so many hot Jupiters because they are the easiest type of planet to find, they are not necessarily particularly common in the galaxy. ... Subsequently several similar hot and€а fuzzy worlds have been discovered the same way, proving this that this planet is not a one-off oddball. ...

... The Russian TESIS/ CORONAS-PHOTON Solar Observatory, which has been working in orbit since January 30th, 2009, has photographed one of the most important events in the build up to the upcoming solar cycle - the formation of our star's new southern belt of activity. The first magnetic fields of the new cycle in the southern hemisphere appeared on the Sun's surface on May 23-24th. ... The belt of activity is one of the primary concepts, characterizing the solar cycle. ...

... Comet Tutorial . ... On July 1, 1993 an image was taken with the Hubble Space Telescope (HST) that clearly shows at least 15 individual fragments in one image frame of the train. ... This made an accurate orbit (or orbits) difficult to determine; however, after numerous observations of the comet, astronmers determined that the comet had passed within 96,000 kilometers (60,000 miles) of the center of Jupiter or 25,000 kilometers (16,000 miles) from the cloud tops during the July 8, 1992, approach. ...
