The optical and infrared instruments of Euclid, ESA's mission to study dark energy and dark matter in space, have passed their qualification and acceptance reviews and are now fully integrated into the spacecraft's payload module. This marks an important step forward in the assembly of the Euclid space telescope, which is scheduled for launch in 2022. The two Euclid instruments, the visibl

The mystery surrounding the whereabouts of a supermassive black hole has deepened. Despite searching with NASA's Chandra X-ray Observatory and Hubble Space Telescope, astronomers have no evidence that a distant black hole estimated to weigh between 3 billion and 100 billion times the mass of the Sun is anywhere to be found. This missing black hole should be in the enormous galaxy in the ce

Although violent and unpredictable, stellar flares emitted by a planet's host star do not necessarily prevent life from forming, according to a new Northwestern University study. Emitted by stars, stellar flares are sudden flashes of magnetic energy. On Earth, the sun's flares sometimes damage satellites and disrupt radio communications. Elsewhere in the universe, however, robust stellar f

While the scientific community grapples with the loss of the Arecibo radio telescope, astronomers who recently revived a long-dormant radio telescope array in Argentina hope it can help modestly compensate for the work Arecibo did in pulsar timing. Last year, scientists at Rochester Institute of Technology and the Instituto Argentino de Radioastronomia (IAR) began a pulsar timing study us

A Southwest Research Institute-led team of scientists has identified a potentially new meteorite parent asteroid by studying a small shard of a meteorite that arrived on Earth a dozen years ago. The composition of a piece of the meteorite Almahata Sitta (AhS) indicates that its parent body was an asteroid roughly the size of Ceres, the largest object in the main asteroid belt, and formed in the

NASA and Boeing engineers successfully completed propellant loading during the seventh core stage Green Run test, wet dress rehearsal Sunday, Dec. 20. The massive Space Launch System (SLS) rocket's tanks were loaded with more than 700,000 gallons of liquid hydrogen and liquid oxygen. Engineers working in the Test Control Center monitored all core stage systems during the test as propellant

Already involved since 2018 in the Altius (Atmospheric Limb Tracker for the Investigation of the Upcoming Stratosphere) stratosphere observation mission at several levels, the software engineering company SPACEBEL is ending the year 2020 in style. The European Space Agency (ESA) has now officially awarded the SME a new contract to supply the payload data ground segment. This operational gr

Having finished its primary mission, the part of China's Chang'e-5 spacecraft that remained in space has departed for a new mission: exploring an unusual area of space known as a Lagrangian point. On December 16, the orbiter vehicle performed the final task of its primary mission when it dropped off the capsule carrying samples from the lunar surface. The capsule plunged back to Earth, bei

Astroscale Holdings Inc. ("Astroscale"), the market leader in securing long-term orbital sustainability, has shipped its End-of-Life Services by Astroscale demonstration (ELSA-d) satellite to Baikonur Cosmodrome in Kazakhstan for a March 2021 launch on a Soyuz rocket. "Shipment is always a significant milestone on any satellite development program," said Gene Fujii, Astroscale Chief Engine
