ISSI calls for proposals from international research teams
AnnouncementThe International Space Science Institute (ISSI) invites proposals from International Teams to carry out research projects in space science in Bern, Switzerland. These projects include fundamental physics and comparative planetology and should be based on the analysis and evaluation of existing data from several spacecraft and eventual integration with ground observations and theoretical models.

Hubble resolves a blaze of stars in galaxy's core [heic0302]
The central region of the small galaxy NGC 1705 blazes with the light of thousands of young and old stars. Astronomers call NGC 1705 a dwarf irregular, that is, a small galaxy lacking regular structure. Knowing how dwarf irregular galaxies evolve tells us a lot about galaxy formation and evolution.

Who knows how many stars there are?
It must be one of the oldest questions. When you gaze at the sky, you marvel at its immensity. Have you ever, at some stage of your life, looked up into the night sky and wondered just how many stars there are in space? The question has fascinated scientists as well as philosophers, musicians, and dreamers through the ages.

OK, our next caller is... from Mars!
It is midnight on 1 January 2004 and you want to send a greeting on your mobile phone to a friend. Sorry, the line is too busy, try again later. If you think you are alone with this problem, you are wrong. Space agencies have had to work out ingenious solutions to prevent similar 'engaged, call later' tones from happening on Mars. For the first time, there will be seven spacecraft on the Red Planet at the same time. Will they all be able to 'phone home'?

ESA PR 10-2003 ESA chairs the International Living With a Star programme
ESA is providing the first chairman for the International Living With A Star (ILWS) programme. ILWS is an unprecedented initiative in which space agencies worldwide are getting together to investigate how variations in the Sun affect the environment of Earth and the other planets, in the short and long term.

The Boomerang Nebula - the coolest place in the Universe? [heic0301]
The Boomerang Nebula is a young planetary nebula and the coldest object found in the Universe so far. The NASA/ESA Hubble Space Telescope image illustrates how Hubble's keen vision reveals surprises in celestial objects.

Bright comet is really NEAT
Comet C/2002 V1 (NEAT) is putting on a fine show for ESA/NASA's Solar and Heliospheric Observatory (SOHO) space probe. As the comet swings closer to the Sun, it has got brighter. Now it is the brightest comet ever observed by SOHO's LASCO instrument.

Greenhouse effects... also on other planets
Our planet is warming up, and experts warn that the consequences will be serious. To see precisely how the process works, scientists need as much information as possible and from many different sources. There are valuable clues out in space. ESA's missions to Venus, Mars, and Saturn's moon Titan will soon provide useful information to understand how our own planet's climate is regulated.

Follow Comet C/2002 V1 (NEAT) with SOHO
Only the most dedicated of sky watchers will have seen the latest comet, called C/2002 V1 (NEAT). It has hovered near the limits of naked-eye visibility in the evening sky since January 2003. However, you would need a pair of binoculars, pointed in exactly the right direction, to see anything. Log onto the Internet instead, and let the ESA/NASA space probe SOHO show you more about this comet than you would usually see.

Landers feel the heat on space missions
Space is certainly a cold place, but spacecraft have to face exteremely high temperatures when they are exposed to the Sun's radiation. However, there are other extreme situations in which spacecraft are subject to tremendous heat. ESA's spacecraft must endure temperatures from hell...

Bifurcation of the Tail Current
The cross-magnetotail current sheet, which separates the northern lobe of the magnetotail from the southern lobe, is one of the key objects of magnetospheric physics.

Measurement of the Electric Current
The prime scientific objective of Cluster is to derive physical quantities, such as the electric current density that can only be obtained by combining measurements from the four spacecraft. A first example where this has been achieved was obtained close to the external boundary of the Earth's magnetic field, in a Flux Transfer Event (FTE).

ESA on the trail of the earliest stars
Somewhere in the distant, old Universe, a population of stars hide undetected. They were the first to form after the birth of the Universe and are supposed to be far bigger in mass than any star visible today.

ESA INFO 1-2003 Rosetta - a comet ride to solve planetary mysteries
ESA's Rosetta will be the first mission to orbit and land on a comet. Comets are icy bodies that travel throughout the Solar System and develop a characteristic tail when they approach the Sun. Rosetta is scheduled to be launched on-board an Ariane-5 rocket in January 2003 from Kourou, French Guiana.

Our Sun does the wave
Our Sun has large features that move across its surface as it rotates. Scientists call them 'supergranules'. Thanks to data from the SOHO spacecraft, scientists believe they have found out why supergranules move faster than the Sun rotates. They do not move faster at all. The apparent rapid rotation is an illusion generated by a pattern of waves, like spectators doing the wave at a sporting event.
