1/ 📢 Hubble’s sharp view captures spokes in #Saturn's rings — the enigmatic features whose presence and appearance vary with the Saturn seasons. The two smudgy spokes can be seen in the B ring, on the left in the image. 👇 esahubble.org/images/opo2305… 2/ Like Earth, Saturn is tilted on its axis and therefore has four seasons, each of them lasting around seven Earth years. Equinox marks the height of spokes’ visibility, while during a solstice the spokes disappear.

1/ 🆕 Three moments in a far-off supernova explosion have been captured by Hubble. The progenitor star exploded over 11 billion years ago. This is the first detailed look at a supernova at such an early time in the Universe’s evolution.

Read more: esahubble.org/news/heic2214/ 2/ This observation was possible due to gravitational lensing: light from distant stars is bent by the gravity of massive galaxies in the way. This light took 3 different paths through the cosmic lens of galaxy cluster Abell 370, showing the supernova in 3 stages of evolution.

1/ Following six years of meticulous observations, Hubble has, for the first time ever, provided direct evidence for a lone black hole drifting through interstellar space by a precise mass measurement of the phantom object. 👇

1/ Using observations from the @HUBBLE_space , as well as @GeminiObs & the NASA Infrared Telescope Facility, researchers explain why Uranus and Neptune are different colours 🔗 esahubble.org/news/heic2209/ @GeminiObs 2/ A new atmosphere model reveals that excess haze on Uranus builds up in the planet’s stagnant, sluggish atmosphere and makes it appear a lighter tone than Neptune.

1/ 🥳 Happy 32, dear Hubble! To celebrate this anniversary, here is an unusual Hubble snapshot: a close-knit collection of five galaxies: the Hickson Compact Group 40. #Hubble32

Full story: 🔗 esahubble.org/news/heic2205/

Details 👇 2/ This menagerie includes three spiral-shaped galaxies, an elliptical galaxy and a lenticular (lens-like) galaxy. Somehow, these different galaxies have crossed paths to create an exceptionally crowded and eclectic galaxy sampler.

Breaking News 📣 #Hubble breaks new record detecting the most distant individual star ever seen. Nicknamed Earendel by the authors, this star existed within the first billion years after the Universe’s birth in the Big Bang 🎆

Full story: 🔗 esahubble.org/news/heic2203/

Thread 👇 📌 The newly detected star is so far away that its light has taken 12.9 billion years to reach Earth, appearing to us as it did when the Universe was only 7% of its current age.

1/6 Here it is! The anniversary image of #Hubble30 features the giant nebula NGC 2014 and its neighbour NGC 2020, part of a vast star-forming region in the Large Magellanic Cloud.

spacetelescope.org/news/heic2007/ 2/6 To commemorate three decades of scientific discoveries using @Hubble_Space , this image is one of the most photogenic examples of the many turbulent stellar nurseries the telescope has observed during its 30-year lifetime.
