On the night of 13 to 14 October, Jupiter's moon #Ganymede will pass in front of star HIP37442.

We know this star's position very well thanks to #ESAGaia 🙏

🔭 Observations of this event will pinpoint Ganymede's position even more precisely. 

More observations, better ephemerides. 2/3

Stars in our galaxy make a stadium wave, Gaia finds 🙌

Our Milky Way galaxy never sits still: it rotates and wobbles 🌀

But #ESAGaia has just revealed that our galaxy also has a giant wave rippling outwards from its centre 👉 www.esa.int/Science_Expl... 🔭 🧪 ☄️
This image consists of two sides. Left side: A top-down view of a spiral galaxy is shown. It has a bright central bulge with several spiral arms radiating outward. Overlaid on the lower part of the galaxy is a data visualisation, with colours ranging from blue to red. A label reading ‘Sun’ marks a specific location within this overlay. Right side: An edge-on view of the same spiral galaxy is presented. It reveals the galaxy's thin disc and central bulge from the side. Coloured points are scattered along the disc, representing the same data as the overlay on the left side. The image features a dark background with a thin, bright horizontal line running across the centre. This is our galaxy’s disc. Above and below this line, numerous white arrows point upward and downward. These arrows vary in length and are spread evenly along the line. Scattered among the arrows are small red and blue dots. The visual resembles an astronomical data visualisation, illustrating positions and motions of stars in our galaxy.

A model image of what our home galaxy, the Milky Way, might look like edge-on, against a pitch-black backdrop. The Milky Way’s disc appears in the centre of the image, as a thin, dark-brown line spanning from left to right, with the hint of a wave in it. The line appears to be etched into a thin glowing layer of silver sand, that makes it look as if it was drawn with a coloured pencil on coarse paper. The bulge of the galaxy sits like a glowing, see-through pearl in the shape of a sphere in the centre of this brown line.

Using #ESAGaia, astronomers at Uni Hawaiʻi discovered the biggest explosions since the Big Bang 💥
All evidence points towards these being caused by supermassive black holes feasting on massive stars.

A view of space with stars in the background. In the foreground is a ring of what looks like dark dust. Swooping into the ring is an orange streak with a bright white light at the end. Inside the bright white light is a black hole.

A model image of what our home galaxy, the Milky Way, might look like face-on: as viewed from above the disc of the galaxy, with its spiral arms and bulge in full view. In the centre of the galaxy, the bulge shines as a hazy oval, emitting a faint golden gleam. Starting at the central bulge, several glistening spiral arms coil outwards, creating a perfectly circle-shaped spiral. They give the impression of someone having sprinkled pastel purple glitter on the pitch-black background, in the shape of sparkling, curled-up snakes.

El telescopio espacial Hubble de la NASA/ESA y #ESAGaia unen sus fuerzas para revisar el destino de nuestra galaxia.

Se pone en duda la predicción largamente sostenida de que la Vía Láctea colisionará con la galaxia de Andrómeda dentro de unos 4.500 millones de años.

A three-panel image, two at the top and one stretched across the bottom. At top left, two spiral galaxies are widely separated against the black background of space. At top right, two face-on spiral galaxies are close together. Their spiral arms appear stretched toward each other. At bottom, two spiral galaxies have collided, resulting in a broad X-shaped patch of milky white. Mottled clouds of dark brown dust are superimposed.
