About 290 million light-years away, Stephan’s Quintet is located in the constellation Pegasus.

It’s notable for being the first compact galaxy group ever discovered.

Four of the five galaxies within the quintet are locked in a cosmic dance of repeated close encounters.

This Webb telescope image doesn’t look that different from the Hubble telescope version at first glance, but the new telescope’s infrared sensitivity will pull out different features for astronomers to study.

And this was the great hope – that we would have Webb working alongside Hubble.

They have different strengths and being able to compare and contrast will give scientists a new dimension to their studies.

We don’t know for how much longer Hubble will operate.

It’s 32 years old and prone to technical glitches. But the officials at Nasa who’re in charge of the old warhorse have just submitted a five-year budget plan.

What exactly can we see in the Southern Ring?

The image of the Southern Ring shows a planetary nebula "caused by a dying star that dispelled a large fraction of its mass in excessive waves", which Nasa says can be seen in the images.

The image shows a bubbly, foamy appearance with some very structured shells, and the orange foam is due to the molecular hydrogen which formed in the expansion, lighting up the gas and dust of the nebula (a body of interstellar clouds).

The blue haze closer to the centre of the image is due to hot ionized gas that is heated by the very hot leftover core of the star.

The rays in the outer regions are holes in the inner nebula which are letting the central stars' light come out, giving the appearance of patchy clouds with the sun shining through.
