Dots

Wow. Just wow.

From Astronomy Picture of the Day for 12/10/19.

On the left the pale blue dot (Earth) as seen from Saturn. On the right Earth and Moon from Mercury.

Galactic Collision

From Astronomy Picture of the Day for 9/10/19.

The aftermath of a collision between the two galaxies NGC 7715 (off to left) with NGC 7714 (centre.)

The bright centre of the swirl is due to a burst of star formation triggered by the collision.

The Jewels in M33

From Astronomy Picture of the Day for 3/10/19.

A beautiful jewel-like pinwheel galaxy as shown by its hydrogen emission lines.

Islands in the Sky

This is from Astronomy Picture of the Day for 2/10/19.

The blurb calls these molecular clouds. They are in the Carina Nebula.

It looks like an aerial shot (or a map) of an archipelago surrounded by muddy water.

Pluto’s True Colours

From Astronomy Picture of the Day, 10/9/19.

Pluto, how it would appear to human eyes. Mostly brown, apparently.

M27

18th century French astronomer, Charles Messier, famously compiled a list of astronomical apparitions that were neither stars, planets, nor comets and which he called nebulae. These became known as Messier Objects and include star clusters, galaxies and “proper” nebulae.

Astronomy Picture of the Day featured one such on 29/8/19. The picture is copyright to A Bob Franke so i have not reproduced it here.

Is it just me or does that planetary nebula look like a biological cell as seen through a microscope?

A Bubble in Space, Shooting

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.

Merging Galaxies

This is just beautiful.

From Astronomy Picture of the Day for 11/8/19.
