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 A new satellite 'Made in Belgium' with SPACEBEL software

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 The upside of volatile space weather

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 On the Hunt for a Missing Giant Black Hole

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 Euclid's optical and infrared instruments integrated in spacecraft

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 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 presence of water under intermediate temperatures and pressures.

The solar system's two biggest planets, Jupiter and Saturn, came within planetary kissing range in Monday's evening sky, an intimacy that will not occur again until 2080.
This "great conjunction", as it is known to astronomers, occurred fortuitously on the winter solstice for those in the Northern Hemisphere and the beginning of summer in the global south.
The two planets were, in fact, more than 730 million kilometres (400 million miles) apart. But because of their alignment in relation to Earth, they appeared to be closer to each other than at any time in almost 400 years.
Optimal "conjunction" took place at 1822 GMT.
The best viewing conditions on Monday were in clear skies and close to the Equator, while people in Western Europe and along a vast swathe of Africa had to train their sight to the southwest.
But hundreds of space fans also gathered in Kolkata to watch—through a telescope at a technology museum in the city, or from surrounding rooftops and open areas.
