It's Stephen Hawking's birthday. The occasion to share this fantastic video he produced as part of his Genius documentatry series. Hawking elaborates on our place in the Universe, including our membership to the Laniakea supercluster of galaxies that we discovered back in 2014.

💁🏻‍♀️ ICYMI: 🌌✨ Astrophotographer Ian Lauer demonstrates why exposure time matters by photographing the #Andromeda Galaxy for 10 seconds, 10 minutes, and 10 hours. The longest exposure reveals dust lanes, companion #galaxies, and details invisible to shorter captures.

We are releasing seven new scientific publications today, based on our Q1 data release earlier this year. All revolve around various aspects of galaxy evolution. They are accompanied by two new image collages:

The first one is a #Euclid-based re-creation of the classical 'morphology tuning fork' of galaxy shapes – the second a near-infrared view into the 'dark cloud' LDN 1641, released by #ESA.
