Sep 30  The filament between us and the Universe
Using complex numerical simulations that follow the evolution of the large scale distribution of matter with time, it is possible to illustrate the complex structure of the Universe. The image above is the result >>>
Sep 29  Terrestrial planets prefer G-type stars
Now that the Kepler space telescope has identified over a thousand potential planets around stars more or less similar to the Sun, the number of scientific publications based on preliminary data has >>>
Sep 28  Cosmic distances can be measured with quasars!
The idea that quasars could be used to measure cosmic distances has been around for over 40 years, but this hope now seems to have become a reality. A viable method now seem to have been >>>
Sep 26  The invisible fall of UARS
The concern over the re-entry of the Upper Atmosphere Research Satellite (UARS) has disappeared suddenly after the fragments of the old laboratory vanished without trace. It would appear that >>>
Sep 23  Neutrinos faster than light?! Hmmm...
A large part of modern physics rests on one notion, that until now has seemed incontrovertible; the finite speed of light in a vacuum: 299,792,458 m/s. That this speed is as fast as anything can >>>
Sep 22  GX 339-4: a close look at a black hole
Though it is true that it is impossible to receive information in the form of light (or any other form) from within a black hole, it is also true that the most recent observations made with orbiting telescopes have >>>
Sep 21  Baptistina didn't kill the dinosaurs
In 2007 a very interesting study was published suggesting that the asteroid that killed the dinosaurs (and numerous other species) came from a collision between asteroid 298 Baptistina and a similar >>>
Sep 20  Earth-Moon systems important for life
As we know, the Earth's natural satellite is very large in proportion to the Earth, so much so that sometimes people speak of a "double planet" when referring to the Earth-Moon system. Although >>>
Sep 19  UARS satellite re-entry is an impact risk
Between 23rd and 24th September the Upper Atmosphere Research Satellite (UARS) will re-enter the Earth's atmosphere and disintegrate almost completely. We stress "almost" though >>>
Sep 16  VSS Enterprise: first launch within 12 months
With a name to live up to, Richard Branson's space ship is ready to become the first private vehicle for sub-orbital, and possibly orbital, flights. The reference to the USS Enterprise from the first Star >>>
Sep 15  How the Galaxy's spiral arms were born
Over the last few years there have several studies that have used supercomputer simulations to investigate the dynamical history of our galaxy, and how this led to it looking like it does today >>>
Sep 14  CoRoT-2b: bombarded by X-rays
Of the extrasolar planetary systems discovered by the French Convection, Rotation and planetary Transits (CoRoT) satellite, there is one that is subjected to such a fierce flux of X-rays from its >>>
Sep 13  A second Earth-like planet discovered
Not since 2007 have astronomers discovered an extrasolar planet so similar to Earth, even if not identical. But this year such a planet has been found, and the details were presented to 350 experts >>>
Sep 12  Gold is made in cosmic collisions
A hypothesis which is widely accepted, but that has never actually been demonstrated, is that all elements heavier than iron originate in supernova explosions. In fact there are some doubts about >>>
Sep 6  Pumice, cradle of life on Earth?
A collaboration between Oxford University and the University of Western Australia has produced some research, the results of which are published in the journal Astrobiology, suggesting that the >>>
Sep 5  Space cleaners on the way
The well known problem of space junk may well soon be treated in the same way as terrestrial rubbish, that is, collected up with purpose-built apparatus and then sent to the incinerator >>>
Sep 2  Discovered: a small star with no metals
In yesterday's issue of Nature, the details of a surprising discovery made by a team of European astronomers with ESO's Very Large Telescope were published. What was discovered was a star of >>>
Sep 1  New SNe remnants in the Galactic plane
A large survey has just been completed that has kept a large number of researchers from the Max Planck Society and the Chinese Academy of Sciences busy for ten years (and taken over 4500 >>>
