The newly-expanded Expedition 48 crew is preparing for next week’s arrival of the ninth SpaceX mission. In the meantime, the International Space Station’s newest trio is getting used to their new home in space and conducting science and maintenance with their crewmates.
New astronauts Kate Rubins and Takuya Onishi joined Commander Jeff Williams and trained for the robotic capture of the SpaceX Dragon. The Dragon cargo craft is scheduled to launch early June 18 from Florida and arrive at t [...]
ESO’s HAWK-I infrared instrument on the Very Large Telescope (VLT) in Chile has been used to peer deeper into the heart of Orion Nebula than ever before. The spectacular picture reveals about ten times as many brown dwarfs and isolated planetary-mass objects than were previously known. This discovery poses challenges for the widely accepted scenario for Orion’s star formation history.
An international team has made use of the power of the HAWK-I infrared instrument on ESO’s Very Large T [...]
The European Space Agency's orbiting X-ray observatory, XMM-Newton, has proved the existence of a "gravitational vortex" around a black hole. The discovery, aided by NASA's Nuclear Spectroscopic Telescope Array (NuSTAR) mission, solves a mystery that has eluded astronomers for more than 30 years, and will allow them to map the behavior of matter very close to black holes. It could also open the door to future investigations of Albert Einstein's general relativity.
Matter falling into a black [...]
Wait for me! In 2011, NASA's robotic mission Juno launched for Jupiter from Cape Canaveral, Florida, USA. Last week, Juno reached Jupiter and fired internal rockets to become only the second spacecraft to orbit our Solar System's largest planet. Juno, tasked with studying the jovian giant over the next two years, is in a highly elliptical orbit that will next bringing it near Jupiter's cloud tops in late August.
Of course, the three-year-old pictured was not able to catch up to the launching [...]
About 250 million light-years away, there's a neighborhood of our universe that astronomers had considered quiet and unremarkable. But now, scientists have uncovered an enormous, bizarre galaxy possibly formed from the parts of other galaxies.
A new study to be published in the Astrophysical Journal reveals the secret of UGC 1382, a galaxy that had originally been thought to be old, small and typical. Instead, scientists using data from NASA telescopes and other observatories have discovered [...]
Jupiter has aurorae. Like Earth, the magnetic field of the gas giant funnels charged particles released from the Sun onto the poles. As these particles strike the atmosphere, electrons are temporarily knocked away from existing gas molecules. Electric force attracts these electrons back.
As the electrons recombine to remake neutral molecules, auroral light is emitted. In the featured recently released composite image by the Hubble Space Telescope taken in ultraviolet light, the aurorae appea [...]
