Professor Avi Loeb, the former chair of astrophysics at Harvard University, believes an object that passed through our solar system had extraterrestrial origins - but his colleagues largely disagreed.
In late 2017, scientists at a Hawaiian observatory glimpsed a strange object soaring through our inner solar system.
The object - dubbed Oumuamua - was pancake-shaped and as big as a football field. It had no tail so wasn t a comet and it was moving too quickly to be an asteroid. ....

Magnetic reconnection refers to the reconfiguration of magnetic field geometry. It plays an elemental role in the rapid release of magnetic energy and its conversion to other forms of energy in magnetized plasma systems throughout the universe.
Researchers led by Dr. LI Leping from the National Astronomical Observatories of the Chinese Academy of Sciences (NAOC) analyzed the evolution of magnetic reconnection and its nearby filament. The result suggested that reconnection is significantly accelerated by the propagating disturbance caused by the adjacent filament eruption. ....

Messier 106 in Canes Venatici - Astronomy Magazine - Interactive Star Charts, Planets, Meteors, Comets, Telescopes

Messier 106 is a spiral galaxy lying 22 million light-years from Earth in the constellation Canes Venatici. It is a Seyfert galaxy with an active nucleus emitting radio waves and X-rays due to presence of a supermassive black hole actively consuming matter within its core. Violent churning of spiral arms, dust clouds, and sprays of ionized hydrogen can be seen revolving around the nucleus. The the irregular galaxy to its lower left is UGC7356 which lies at a similar distance and the edge on spiral galaxy to its lower right is NGC 4248 which lies 24 million light-years away. Other faint, distant galaxies can be seen scattered around the image. ....
