During 1998 Dr Gerry Doyle was involved with three PPARC PDRA research grants, and was also a co-organiser of two international conferences (the COSPAR Symposium `Activity Observed in the Sun and in Similar Stars', and the Armagh Cool Star Workshop `Solar and Stellar Activity: Similarities and Differences'). He was Associate Scientist with the CDS and SUMER instruments on SOHO. ...

... Astronomers once thought Pluto's atmosphere would condense down to the surface as it moved away from the Sun. Can that still be true, and if so, is that causing the surface features we now see? ... This is almost certainly because the atmosphere which is nitrogen, like Earth s atmosphere is also frozen as ice on the surface. ... Get instant access to subscriber content on Astronomy.com! ...

... October 4, 1995 . The Sun Spews X-rays . Credit: Yohkoh Soft X-ray Telescope , ISAS , Japan . Explanation: Our Sun is really very hot. The Sun's outer atmosphere is so hot that it emits much light in the X-ray band, which was unexpected. X-rays are usually emitted from objects having a temperature in the millions of degrees, not the mere thousands of degrees of the Sun's surface. The above X-ray picture shows the Sun one particularly active day in August of 1992. ...

ARECIBO, P.R. -- The smog-shrouded atmosphere of Titan, Saturn's largest moon, has been parted by Earth-based radar to reveal the first evidence of liquid hydrocarbon lakes on its surface. The observations are reported by a Cornell University-led astronomy team working with the world's largest radio/radar telescope at the National Science Foundation's (NSF) Arecibo Observatory. ... The piggybacking Huygens probe is scheduled to plunge into the hazy Titan atmosphere and land on the moon's surface. ...

In this gallery are many images of Low Surface Brightness Galaxies which have recently been discovered and analyzed. ... The central surface brightness of this galaxy is 24.28 . Malin 2 This galaxy is another huge disk galaxy with a scale length of 15 kpc and a redshift of 15000 km/a. The high surface brightness knot in one of its spiral arms actually has the same color, luminosity and H-alpha equivalent width as the entire Large Magellanic Cloud . ... Truly it is a Low Surface Brightness Galaxy. ...

... 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. ...

... We couldn't ask for better weather on planet Zoltex. ... These use information collected by satellites surrounding the Earth to monitor our weather. ... Now astronomers are starting to map the weather on other worlds well beyond our Solar System. Using very powerful telescopes, scientists have just created the first ever map of the weather on a brown dwarf! Using a clever technique astronomers were able to create a map of the dark and light patches on its surface. ...

... Planets . ... The planets were found using the HARPS instrument on the 3.6m telescope at ESOтАЩs La Silla Observatory. ... A planet in orbit around a star causes the star to regularly move towards and away from observers on Earth. ... One newly discovered planet, HD 85512 b, is best hope found so far for a habitable exoplanet. ... The HARPS team so far have found that about 40% of stars similar to own Sun have at least one planet smaller than Saturn (which is 95 times more massive than Earth). ...

... When the Voyager 2 spacecraft flew by the planet Uranus in January 1986, astronomers were treated to their first close-up glimpse of the satellites that orbit the seventh planet. ... But by far the most intriguing of those 15 satellites was a jigsaw-puzzle world called Miranda . ... How dark was it at Miranda? One of the Voyager scientists put it this way: Taking pictures in the Uranus system is like trying to do photography in a ballpark at night when the only light comes from a single candle. ...

... Astronomers of the SAO together with an international group of scientists have proposed an explanation to the long-standing mystery of why magnetic fields are more common amongst cool white dwarf stars than amongst young and hotter ones. ... As the result magnetic white dwarfs demonstrate excess in their frequencies in the temperature range below 14000K. The authors also show that the strongly magnetic white dwarfs are of the oldest stars of the Galaxy originated from intermediate-mass relic stars. ...
