Recent observations with the Hubble Space Telescope suggest that the first stars formed as little as 200 million years after the Big Bang. This is much earlier than previously thought. Astronomers have observed large amounts of iron in the ultraluminous light from very distant, ancient quasars. This iron is the 'ashes' left from supernova explosions in the very first generation of stars.

Like the fury of a raging sea, this anniversary image from the NASA/ESA Hubble Space Telescope shows a bubbly ocean of glowing hydrogen, oxygen, and sulphur gas in the extremely massive and luminous molecular nebula Messier 17.

Constants govern the way our Universe behaves. We regard them as fixed, unchanging quantities. However, how can we be sure that constant really means constant? Modern theories require the values of universal constants to slowly change during the course of cosmic history. Is this the case? ESA is preparing to search for (small) changes in the 'constants of nature'.

When ESA's Mars Express reaches the Red Planet in December 2003, there will be a drill on board its Beagle 2 lander. This drill will dig into the surface to take samples of the Martian rocks. Who would imagine that the creativity of an enthusiastic dentist is behind a 'cosmic' drill?

Titan, Saturn's largest moon, is a mysterious place. Its thick atmosphere is rich in organic compounds. Some of them would be signs of life if they were on our planet. How do they form on Titan? Will they help us to discover how life began on Earth?

In January 2002, a moderately dim star in the constellation Monoceros, the Unicorn, suddenly became 600 000 times more luminous than our Sun. This made it temporarily the brightest star in our Milky Way. The light from this eruption created a unique phenomenon known as a 'light echo' when it reflected off dust shells around the star.

Using the Hubble Space Telescope, for the first time, astronomers have observed the atmosphere of an extrasolar planet boiling off into space. Much of this planet may eventually disappear, leaving only a dense core. The planet is an example of a type of exoplanet known as a 'hot Jupiter'. These giant, gaseous planets orbit their stars very closely, drawn to them like moths to a flame.

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.

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.

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.

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'?
