Instrument Science Report WFC3 2008-07 WFC3 TV3 Testing: UVIS Channel Glints Thomas M. Brown Apr 14, 2008 ABSTRACT In the previous thermal vacuum (TV) campaign of 2007, it was discovered that the UVIS channel was subject to strong glints (containing ~1% to 30% of the source energy) due to reflections between the CCD surface and the CCD housing. ... These glints contained anywhere from 1% to 30% of the source energy and spanned thousands of pixels. ... 2001, ISR WFC3 2001-17). ...

... 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 coordinate systems must be updated when the data (pixel data, other keywords, related tables) are altered (eg. rebinning of the image). ...

... This artist's impression shows the remarkable planetary system around the Sun-like star HD 10180 five planets and evidence for two more. ... Richest Planetary System Discovered . ... This remarkable discovery also highlights the fact that we are now entering a new era in exoplanet research: the study of complex planetary systems and not just of individual planets. ... The newly discovered system of planets around HD 10180 is unique in several respects. ...

So how do we find objects on the other side of the Universe? ... The latest instruments enable us to scan large areas of sky. Using Cerro Tololo's Blanco 4m telescope and the Canada-France-Hawaii 3.5 metre telescope , we are able to scan a piece of sky larger than the size of the moon every 5 minutes to a faintness level which allows us to find Type Ia supernovae halfway across the Universe. Type Ia supernovae are very rare - but each image we take contains 50000 galaxies. ...

... Massive stars, having 10-150 masses of the Sun, with metallicities Z tens to hundreds times less than that of the Sun (Zo), are the main regulators of the galaxy formation and evolution processes in the early Universe. ... In this galaxy, using the 6 m BTA telescope, a new massive blue variable star with high luminosity (>=10 5 Sun's luminocities in visible light) was found. As far as its properties are concerned, this star falls into an LBV (Luminous Blue Variable) class of stars. ...

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." ...

... Credit: Rob van Gent , Tiemen Cocquyt , and Carl Koppeschaar Explanation: In 1655, three hundred fifty years ago on this date, Dutch astronomer Christiaan Huygens discovered Luna Saturni - now known as Saturn's moon Titan. To celebrate, consider this intriguing picture of his telescope lens, all that remains of the instrument he used , designed and constructed in collaboration with his brother, Constantijn Huygens. ... Huygens used the verse as part of an anagram announcing his discovery. ...
