Astrophysicists have found evidence strongly supporting a solution to a long-standing puzzle about the birth of some of the most massive stars in the universe. Young massive stars shine brightly in the ultraviolet, heating the gas around them, and it has long been a mystery why the hot gas doesn't explode outwards. Now, observations have confirmed predications that as the gas cloud collapses, it forms dense filamentary structures that absorb the star's ultraviolet radiation.
For decades, astrophysicists have encountered a contradiction: although many galactic-wind models - simulations of how matter is distributed in our universe - predict that most matter exists in stars at the center of galaxies, in actuality these stars account for less than 10 percent of the matter in the universe. New simulations offer insight into this mismatch between the models and reality: energy released by individual stars can have a substantial effect on where matter ends up.
The VLT Survey Telescope (VST) at ESO's Paranal Observatory in Chile has captured this richly detailed new image of the Lagoon Nebula. This giant cloud of gas and dust is creating intensely bright young stars, and is home to young stellar clusters. This image is a tiny part of just one of eleven public surveys of the sky now in progress using ESO telescopes. Together these are providing a vast legacy of publicly available data for the global astronomical community.
The first Near-Earth Object (NEO) recovery campaign has been successfully carried out by a new collaboration between the European Space Agency (ESA) and ESO. Up to now the asteroid 2009 FD had been ranked among the top five objects in a list of the most dangerous objects, but new observations with ESO's Very Large Telescope (VLT) have now shown that it is far less likely to hit the Earth than had been feared.
A comet heading towards Earth threatens humanity's existence - that was the virtual scenario of this year's Zero Robotics tournament. Secondary-school students from across Europe controlled miniature satellites on the International Space Station in a competition to save our planet.
After a ten-year journey and a long, deep sleep the Rosetta space probe will be awoken on 20 January. The vehicle then starts the last leg of its journey which will lead it to the 67P/Churyumov-Gerasimenko comet. The Philae lander is to descend to the comet's surface in November.
A team of Japanese astronomers has obtained a firm evidence of formatino of a giant planetary system around a young star by the observations with the Atacama Large Millimeter/submillimeter Array (ALMA). This result has a transformative impact on the theories of planet formation and gives us a clue to the origin of a wide variety of planetary systems.
The Chang'e-3 lunar probe has started its long-term scientific missions and will have its durability tested when it continues lunar surface surveys, sources with the Beijing Aerospace Control Center said on Thursday.
A comet-bound spacecraft that's been in sleep mode for more than two years is scheduled to wake up on the morning of Jan. 20 - beginning the home stretch of its decade-long journey to a mile-wide ball of rock, dust and ice.
The Monitor of All-sky X-ray Image (MAXI) collects data that help researchers discover, study and understand the physics behind the lifecycle of our universe. MAXI was key in two recent publications sharing results that make strides in advancing astrophysics.
