Hubble finds planetary transition point
The results help to confirm the view that other planetary systems form in ways similar to our solar system. The Kuiper belt is a disk of dust, gas and icy comets stretching from 40 to 10000 times the ...

Hubble constant starts to settle down
The Hubble team, led by Wendy Freedman of the Observatories of the Carnegie Institution of Washington, has spent the last eight years using the telescope to make more accurate measurements of the Hubb...
Galactic nuclei outdistances quasars
Wil van Breugel from the Lawrence Livermore Laboratory and colleagues from the University of California, Berkeley and Leiden Observatory in the Netherlands found their galactic nucleus by looking for ...
How are galaxies made?
Galaxies have been forming since the universe was less than 10% of its current age – as supercomputer simulations predict and observations have confirmed

Array signals new era of ground-based astronomy
ALMA will gather highly red-shifted radiation from the furthest stars and galaxies, and will allow astronomers to observe cool dark objects such as brown dwarfs and interstellar dust clouds. The ALMA ...
The most distant object in theuniverse
Galaxies with extremely large redshifts are hard to detect as the radiation they emit shifts to longer wavelengths that are easily absorbed by giant intergalactic hydrogen clouds. Another problem is t...
String theory tops thebest-seller list
String theory is seen as a way of reconciling Einstein’s theory of relativity with quantum mechanics. According to the theory, the fundamental particles and their interactions are generated by t...
Science chooses accelerating universe as “Breakthrough of the Year”
Astronomers have known for decades that the universe is expanding, based on measurements of the “red shift” of light emitted by galaxies. According to the standard cosmological model, ther...
