From Astronomy Picture of the Day for 13/8/19.
This shows the trail of a pulsar (PSR J0002+6216) – travelling at a speed greater than 1,000 kilometres a second – after it had been shot out from a supernova. The bubble it appears to come from is the expanding remnant of the supernova.
The picture is a combination of radio and infra-red data.

A beautiful picture from Astronomy Picture of the Day for 3/6/2019.
Stephan’s Quintet, five galaxies appearing in close proximity from our perspective. Only the four redder ones are really close to each other though – so close they interfere with each others’ structures.

This is a (speeded up) sequence showing the partial eclipse of the Sun by a moon of another planet. From You Tube via Astronomy Picture of the Day for 10/4/19.
The moon is Phobos; the planet, Mars. The sun is the Sun.

I suppose everyone’s seen this by now; it’s been on the TV news and in all the newspapers.
Picture from The Daily Galaxy.
According to Astronomy Picture of the Day on 11/4/19 the black area isn’t the black hole but rather its shadow.
Still, to be able to image it at all is astounding.

This is from Astronomy Picture of the Day for 25/3/19. An astonishing photograph of two galaxies in the process of merging after one having passed through the other. The most curious feature is the trail of stars forming in between the upper and lower portions – not a usual consequence of such a situation.
The whole does look, though, a bit like an alien’s head or a slightly distorted question mark.

Another great picture of a galaxy courtesy of NASA – via Astronomy Picture of the Day for 17/3/19.
It’s thought that huge amounts of glowing gas are falling into the galaxy’s central black hole.
This is M106:-
