A star thought to have passed the age at which it can form planets may in fact be creating new worlds. The disk of material surrounding the surprising star called TW Hydrae may be massive enough to make even more planets than we have in our own solar system.
They fit in your hand, weigh no more than a bag of sugar, yet fly in space and perform experiments. They are CubeSats, a new generation of miniature satellites. Now, ESA is looking for the best student-built CubeSats to launch into space.
Networks of narrow ridges found in impact craters on Mars appear to be the fossilized remnants of underground cracks through which water once flowed, according to a new analysis by researchers from Brown University.
The UNAWE (Universe Awareness) project is developing "Universe in a Box", a low-cost activity kit to help teachers introduce astronomy to their students. It provides both practical activities and the materials needed.
Initially only operable from a desktop computer, with the approach outlined in the study, THOR is now accessible online from NASA's Precipitation Processing System website. This allows researchers to remotely examine the 15-year archive of Tropical Rainfall Measuring Mission (TRMM) satellite data.
Pulsars - tiny spinning stars, heavier than the sun and smaller than a city - have puzzled scientists since they were discovered in 1967. Now, new observations by an international team make these bizarre stars even more puzzling.
A University of Alberta professor has revealed the workings of a celestial event involving binary stars that produce an explosion so powerful its luminosity ranks close to that of a supernova, an exploding star.
While studying a meteorite from Vesta, geoscientists found evidence that planet-like dynamic processes also occurred in the asteroid. Simulations by scientist Gregor Golabek from ETH Zurich confirmed this assumption.
