The nearby radio galaxy M87, located 55 million light-years from the Earth and harboring a black hole 6.5 billion times more massive than the Sun, exhibits an oscillating jet that swings up and down with an amplitude of about 10 degrees, confirming the black hole's spin.

The Moon and Mars are stated targets of European and international space exploration. However, before humans embark on these journeys, robots will explore inhospitable areas, develop local resources and prepare for the landing of astronauts as comprehensively as possible.
Exploration missions with autonomous mobile robots will therefore increase significantly in the coming years. To facili FAA closes New Shepard mishap investigation

Caves were some of humanity's first shelters. Who knows what our distant ancestors were thinking as they sought refuge there, huddling and cooking meat over a fire, maybe drawing animals on the walls. Caves protected our ancient ancestors from the elements, and from predators and rivals, back when sticks, stones, furs and fire were our only technologies.
So there's a poetic parallel between early humans and us. We're visiting the moon again, and lunar caves could shelter us the way caves sheltered our ancestors on Earth.
On the moon, astronauts will need protection from a different set of hazards. They'll have to contend with cosmic and solar radiation, meteorites, wild temperature swings, and even impact ejecta.
Vega's fuel-free CubeSats will use wings to keep in formation

Spain's trio of ANSER CubeSats, due to fly on Europe's next Vega launcher, will fly like a flock of birds in orbit—in more ways than one. Keeping in formation by following their leader, the three shoebox-sized satellite will image Iberian waters as if they are a single standard-sized mission. And they will unfurl wing-like flaps to maintain their relative positions, surfing on the scanty airflow at the top of Earth's atmosphere.
ANSER—Advanced Nanosatellite Systems for Earth-observation Research—is a cluster of three CubeSats which will work together in close vicinity as if they are a single satellite. Due to be launched on Europe's next Vega flight, VV23, the ANSER mission is being undertaken by INTA, the Spanish Institute of Aerospace Technology.
Santiago Rodriguez Bustabad, overseeing the mission, explains, "ANSER is also the Latin name for the wild goose, a good example of birds flying in formation, adopting a leader-follower protocol, which is what our mission is emulating."
These three-unit CubeSats will orbit around 500 km altitude, maintaining formation at an optimum 10 km apart from each other. But they do not have any onboard propulsion systems.

ESA’s Hera asteroid mission for planetary defence seen with one of its two solar wings added, during its continuing test campaign at the ESTEC Test Centre in the Nethelands.
The van-sized spacecraft, left, is powered by a pair of solar array wings, made up of three panels each, provided by Beyond Gravity in Switzerland.
One of these 5-m-long wings was added for Hera’s ‘cold deployment check’ – a manual unfolding process to confirm that the wing fits correctly. Because the solar wings have been designed to operate in weightlessness they were supported by a frame during this test
