NASA has released a new Hubble image. It's composed of 7500 exposures taken over 16 years.

Some 256 thousand galaxies are shown in the image, which from Earth's perspective, is about the size of the moon. The most distant galaxies are shown as they were just 500 million years after the Big Bang.

It is amazing how much the Hubble has advanced our understanding of the universe.

Jupiter's iconic storm is dying.

Over the past week, amateur astronomers around the world have seen some unusual activity around the solar system's largest and longest-lasting storm, known as the Great Red Spot (GRS).

The swirling red clouds that have been raging over the giant planet for centuries have been spotted forming "propellers" along the storm's edges, with these blade-like shapes spinning off and ultimately dissipating.

The Great Red Spot is massive — roughly 13,000 kilometres in diameter — and it's been around for at least 400 years. But it has consistently been getting smaller. Decades ago, it could fit three Earths inside it. Now, it's the size of just one Earth.
