INFO 19-1998: SOHO sees two comets plunge into Sun
In a rare celestial spectacle, two comets have been observed plunging into the Sun's atmosphere in close succession, on June 1 and 2. This unusual event on Earth's own star was followed on June 2 by a likely unrelated but also dramatic ejection of solar gas and magnetic fields on the southwest (or lower right) limb of the Sun.

Huygens Radio Receiver Test
The Huygens off-Sun AGC calibration test was successfully executed on 28 May at 22:04 UTC. The test lasted 33 minutes, including thetwo manoeuvres required to point Cassini's high-gain antenna (HGA) 12 deg away from the Sun and back. The purpose of the test was tocalibrate the automatic gain control (AGC) level of the Huygens receivers in a radio-noise free environment.

INFO 18-1998: Solar flare leaves sun quaking
Scientists have shown for the first time that solar flares produce seismic waves in the Sun's interior that closely resemble those created by earthquakes on our planet. The researchers observed a flare-generated solar quake that contained about 40 000 times the energy released in the great earthquake that devastated San Francisco in 1906. The amount of energy released was enough to power the United States for 20 years at its current level of consumption, and was equivalent to an 11.3 magnitude earthquake, scientists calculated.

INFO 16-1998: Hubble provides multiple views of how to feed a black hole
Astronomers have obtained an unprecedented look at the nearest example of galactic cannibalism - a massive black hole hidden at the center of a nearby giantgalaxy that is feeding on a smaller galaxy in a spectacular collision. Such fireworks were common in the early universe, as galaxies formed and evolved, but are raretoday.

UV astrophysics beyond the IUE Final Archive
The Conference "UV Astrophysics beyond the IUE Final Archive" (11-14 November 1997) was organised to mark the end of the International Ultraviolet Explorer (IUE)project by the three Agencies responsible for the design and operations of this ultraviolet telescope in space. It represented the last time that thelarge community of astronomers utilising this amazing Space Observatory would get together to review the progress made in astrophysics usingthe results of IUE.

Gamma-ray burst most energetic event in the Universe!
A team of astronomers from the California Institute of Technology announced today that a recently detected cosmic gamma-ray burst was as bright as the rest of the universe, releasing a hundred times more energy than previously theorized.

INFO 15-1998: Surprises from SOHO include tornadoes on the Sun
The Sun has tall gyrating storms far larger and faster than tornadoes on the Earth. This unexpected finding is among the latest results from the solar spacecraft SOHO, to be announced at a European Space Agency press briefing on 28 April. British scientists discovered the solar tornadoes in images and data from SOHO's scanning spectrometer CDS. So far they have detected a dozen such events. They occur most frequently near the north and south poles of the Sun and are almost as wide as the Earth.

INFO 13-1998: Ulysses comes full circle, before revisiting the Sun's poles
On 17 April, after travelling for more than seven years and covering 3.8 billion kilometres, the space probe Ulysses will complete its first orbit of the Sun. Built in Europe for the European Space Agency, this intrepid explorer has ventured into regions never before visited by any spacecraft. It has journeyed far away from the realm of the planets and gone over the poles of the Sun.

INFO 12-1998: ISO finds a very steamy cloud in interstellar space
Although ISO observations finished on 8 April, new results continue to pour as astronomers process their ISO data. A team of American astronomers has discovered a large concentration of water vapour in a cloud of interstellar gas close to the Orion Nebula.

INFO 11-1998: ISO completes its observations of the Universe by infrared light
ESA's Infrared Space Observatory, ISO, has ended its observational phase, long after the expiry date of the end of May 1997 foreseen in the specifications for the mission. Instead of the required 18 months, the astronomers have been able to use ISO for more than 28 months, and as a result have gathered a wealth of additional information about the Universe. Altogether ISO has made over 26 000 observations of cosmic objects.

INFO 09-1998: New water and remote galaxies complete ISO's observations
Water vapour detected on Saturn's largest moon, Titan, and infrared galaxies identified atimmense distances are among the latest results from ESA's Infrared Space Observatory (ISO). At a press briefing in London on 7 April, ESA's director of science, Roger Bonnet, said "ISO is one of the most successful space observatories, and in the infrared it has had no rival." Its discoveries will change our views on the Universe.

PR 08-1998: Hipparcos reveals that the Milky Way is changing shape
Data of exceptional accuracy, from ESA's star-mapping satellite Hipparcos, show that distant stars aremoving in unexpected directions. Their strange behaviour could mean that the shape of the Milky Way Galaxy is changing. Ateam of astronomers from Turin Observatory and Oxford University announced the discovery in the 2 April issue of theLondon science journal Nature.
