Turning to unusual wavelengths, astronomers reveal new pictures of the universe. This article describes a major new gamma-ray window opening up soon in Southern Africa.
April and May were exciting months for cosmologists, as new results brought them one step closer to unravelling the mysteries of the early universe.
Five European countries have pledged to collaborate on research into astroparticle physics. The Astro-Particle Physics European Coordination (APPEC) network was formed on 2 May in Paris. Its goals inc...
Images of a supernova 10 billion light-years from Earth give new weight to the theory of negative pressure (Einstein’s cosmological constant). The observations of the exploding star, made using ...
At the Gamma Ray 2001 conference in Baltimore, Luigi Piro of the Istituto Astrofisica Spaziale in Rome presented new evidence linking gamma-ray bursts to dense regions of star formation. Gamma-ray bur...
On the night of 12 March, the Keck interferometer in Hawaii began operations. It is currently the largest optical telescope in the world, with a resolution equivalent to that of a single telescope wit...
NASA has chosen the first six science projects for its Space Infrared Telescope Facility (SIRTEF). By far the biggest chunk of observing time will go to the Black Holes and Galaxies project – an...
The first measurement of uranium outside our solar system suggests that the universe is at least 12.5 billion years old. Just as the radioactive decay of carbon-14 is used for dating archaeological re...
Observations using the European Southern Observatories’ Antu telescope in Chile are helping to shed light on the mystery of star formation. Stars form from interstellar clouds of gas and dust th...
Radio observations have shown the presence of black holes in the centre of early galaxies. The new results support the theory that supermassive black holes played a crucial role in the formation of ga...
