This is an image (from Astronomy Picture of the Dayfor 17/11/21) of two galaxies overlapping.

The front one’s spiral arms show up almost as shadows against the further one but overall tThe two together look like a sketch of a bird in flight.

The Sun is an unbelievably violent object. Not surprising given its temperature and the countless nuclear reactions taking place in its interior.

Sometimes this violence manifests itself in eruptions like the filament pictured below, which rose from the Sun last month.

A beautiful spiral galaxy. The image shows emissions from hydrogen atoms, emphasising the reddish glow of the parts of the galaxy where stars are forming.

The galaxy looks slightly different in visible light.

This lovely picture comes from NASA via the Hubble Telescope and Astronomy Picture of the Day for 28/7/21. The galaxy’s distorted shape is due to it having interacted with another galaxy (top right) which passed through it.

This is from NASA via Astronomy Picture of the Day for 18/7/21.

The Andromeda Galaxy as seen in ultra-violet light. Compared to visible light images it really picks out the spiral arms but makes them look more like rings.

This beautiful celestial apparition is known as the Necklace Nebula. It is a so-called planetary nebula. These are formed by gases thrown off by stars nearing the end of their lives. The Nebula Necklace’s “Diamonds” are knots of glowing gas.

Only 24 people have ever had the chance to see a view like this – or photograph it. The 24 astronauts of the Apollo Programme who made it to the Moon and back.
