Astronomers have uncovered a supermassive black hole that has been propelled out of the center of a distant galaxy by what could be the awesome power of gravitational waves. Though there have been several other suspected, similarly booted black holes elsewhere, none has been confirmed so far. Astronomers think this object, detected by NASA's Hubble Space Telescope, is a very strong case. Weighing more than 1 billion suns, the rogue black hole is the most massive black hole ever detected...

Around 250 million measurements taken by ESA's CryoSat over the last six years have been used to create a unique 3D view of Antarctica, offering a snapshot of the undulating surface of this vast ice sheet. CryoSat's radar altimeter detects tiny variations in the height of the ice across the entire continent, including on the steeper continental margins where the vast majority of ice losses occur. Importantly, the satellite's orbit takes it to latitudes within 200 km of the north and south ...

NASA has selected a science mission that will measure emissions from the interstellar medium, which is the cosmic material found between stars. This data will help scientists determine the life cycle of interstellar gas in our Milky Way galaxy, witness the formation and destruction of star-forming clouds, and understand the dynamics and gas flow in the vicinity of the center of our galaxy. The Galactic/Extragalactic ULDB Spectroscopic Terahertz Observatory (GUSTO) mission, led by principal in...

Information from ESA's magnetic field Swarm mission has led to the discovery of supersonic plasma jets high up in our atmosphere that can push temperatures up to almost 10 000oC. Presenting these findings at this week's Swarm Science Meeting in Canada, scientists from the University of Calgary explained how they used measurements from the trio of Swarm satellites to build on what was known about vast sheets of electric current in the upper atmosphere. The theory that there are huge electri...

Designers of future Moon missions and bases have to contend with a chilling challenge: how might their creations endure the fortnight-long lunar night? ESA has arrived at a low-cost way of surviving. During prolonged night, when the surface is lit only by blue Earthlight, temperatures dip below -170C. Some locations at higher latitudes have shorter nights, though others have much longer or even permanent darkness. Numerous robotic missions have perished during this prolonged cold. Russia'...

Consider that the Earth is just a giant cosmic dust bunny-a big bundle of debris amassed from exploded stars. We Earthlings are essentially just little clumps of stardust, too, albeit with very complex chemistry. And because outer space is a very dusty place, that makes things very difficult for astronomers and astrophysicists who are trying to peer farther across the universe or deep into the center of our own galaxy to learn more about their structure, formation and evolution. Buildi...

Space Situational Awareness remains a key priority for armed forces capable of operating above the Earth. Space is now extremely contested, congested and competitive as more and more countries and organisation gain access to space technology. However, high amounts of orbiting traffic is not the only threat; space weather, debris and ground based electronic and cyber threats could also have a massive impact on our operations by disrupting satellite activity and therefore military ability on the...

Arianespace’s second Ariane 5 launch of 2017 has been rescheduled for March 23, as continuation of the social movement in French Guiana has prevented today’s transfer of the heavy-lift vehicle to its ELA-3 launch zone. If the situation permits, the mission – designated Flight VA236 in Arianespace’s numbering system – will lift off on March 23 as early as possible within the following window: Between 4:31 p.m. and 7:20 p.m., Washington D.C. time Between ...

Rosetta scientists have made the first compelling link between an outburst of dust and gas and the collapse of a prominent cliff, which also exposed the pristine, icy interior of the comet. Sudden and short-lived outbursts were observed frequently during Rosetta's two-year mission at Comet 67P/Churyumov-Gerasimenko. Although their exact trigger has been much debated, the outbursts seem to point back to the collapse of weak, eroded surfaces, with the sudden exposure and heating of volatile m...

ESA's Swarm satellites are seeing fine details in one of the most difficult layers of Earth's magnetic field to unpick - as well as our planet's magnetic history imprinted on Earth's crust. Earth's magnetic field can be thought of as a huge cocoon, protecting us from cosmic radiation and charged particles that bombard our planet in solar wind. Without it, life as we know it would not exist. Most of the field is generated at depths greater than 3000 km by the movement of molten iron in ...

ESA astronaut Thomas Pesquet will make two more spacewalks under NASA's plans to maintain the International Space Station during his mission. Though intended for the end of March and April, the dates may change because the sorties require equipment yet to be launched on a Cygnus supply vessel. The first will see Thomas and NASA astronaut Shane Kimbrough head outside to install a new computer, work on the electrical power distribution system, and disconnect a docking adapter to allow its mo...

Demanding electric, magnetic and power requirements, harsh radiation, and strict planetary protection rules are some of the critical issues that had to be tackled in order to move ESA's Jupiter Icy Moons Explorer - Juice - from the drawing board and into construction. Scheduled for launch in 2022, with arrival in the Jovian system in 2029, Juice will spend three-and-a-half years examining the giant planet's turbulent atmosphere, enormous magnetosphere, its set of tenuous dark rings and its sa...
