Plants will play a critical role in the survival of human beings on long-duration space missions, such as a mission to Mars. However, as a new study shows, many challenges need to be addressed if astronauts are to successfully grow enough food on board spacecraft and on other planets.
Astronomers found signs of a growing planet around TW Hydra, a nearby young star. Based on the distance from the central star and the distribution of tiny dust grains, the baby planet is thought to be an icy giant, similar to Uranus and Neptune in our Solar System.
New research findings explain why the universe has enough energy to become transparent. The study marks the first quantitative study of how the gas content within galaxies scales with the amount of interstellar dust.
Astronomers have created the most detailed computer simulation to date of our Milky Way galaxy's formation, from its inception billions of years ago as a loose assemblage of matter to its present-day state as a massive, spiral disk of stars.
From November 12 to 15, the Technical University of Munich will host the 'European Space Elevator Challenge' for the third time, an international competition for developing space elevator prototypes. Seven teams from Germany, India and Japan will be competing with their concepts - in the hope of laying the foundation for a revolution in astronautics.
The comet lander Philae has been found. The OSIRIS camera on board the Rosetta orbiter took the revealing images of the surface of Comet 67P/Churyumov-Gerasimenko. They show the landing craft lying sideways in a crevasse.
Using colors to identify the approximate ages of more than 130,000 stars in the Milky Way's halo, Notre Dame astronomers have produced the clearest picture yet of how the galaxy formed more than 13.5 billion years ago.
If two galaxies collide, the merging of their central black holes triggers gravitational waves, which ripple throughout space. An international research team has now calculated that this occurs around 10 million years after the two galaxies merge - much faster than previously assumed.
