Earth eggs are nutritious and all, but space eggs are more eggciting! 🥚
The Egg Nebula, captured by @hubbleesa, offers astronomers a special look at the normally invisible dust shells swaddling an ageing star; while the golden egg was floating in the microgravity of Spacelab-D1 when it was captured by Wubbo Ockels in 1985.

It's been 14 years already‼️ •
Observing the surface of Saturn’s largest moon, Titan, in visible light is difficult due to the globe-enshrouding haze that envelops the moon. On 14 January 2005, the mystery as to what lay beneath the thick atmosphere was revealed as our Huygens probe – carried to Titan by Cassini – made the first successful landing on a world in the outer Solar System. During the two-and-a-half hour descent under parachute, features that looked remarkably like shore lines and river systems on Earth appeared from the haze. But rather than water, with surface temperatures of around –180ºC, the fluid involved here is methane, a simple organic compound that also contributes to the moon’s obscuring atmosphere.

Hubble Time! 🌌⠀⠀⠀
It might appear featureless and unexciting at first glance, but NASA/ESA Hubble Space Telescope observations of this elliptical galaxy — known as Messier 105 — show that the stars near the galaxy’s centre are moving very rapidly. Astronomers have concluded that these stars are zooming around a supermassive black hole with an estimated mass of 200 million Suns! This black hole releases huge amounts of energy as it consumes matter falling into it and causing the centre to shine far brighter than its surroundings. This system is known as an active galactic nucleus.

Shine dim like a crystallised white dwarf 💎 •
Data captured by our galaxy-mapping spacecraft Gaia has revealed for the first time how white dwarfs, the dead remnants of stars like our Sun, turn into solid spheres as the hot gas inside them cools down.

Have you heard the story of the desert that ate the sea? ⏳
This Proba-V view shows all that is left of the Aral Sea, once one of the four largest lakes in the world and now one of the world’s major ecological disaster areas. It has shrunk into separate lakes, surrounded by Earth’s youngest desert.

We achieve great things working together‼️💪
Our high-energy space telescopes Integral and XMM-Newton have helped to find a source of powerful X-rays at the centre of an unprecedentedly bright and rapidly evolving stellar explosion that suddenly appeared in the sky earlier this year.
The ATLAS telescope in Hawaii first spotted the phenomenon, since then named AT2018cow, on 16 June. Soon after that, astronomers all over the world were pointing many space- and ground-based telescopes towards the newly found celestial object, located in a galaxy some 200 million light years away.

Sending our warm thoughts to everyone affected by these snowstorms. •
Snow, snow...and more snow ❄️❄️❄️
While snow continues to cause chaos in Austria and Germany, the cold snap has also reached Turkey as shown in this @copernicus_eu Sentinel-3 image from 9 January. The snow, which started falling in Turkey on Sunday, 6 January, has led to villages in remote areas being cut off and the authorities having to close offices and schools. .

The power of gravitational lensing! 🔍
The NASA/ESA Hubble Space Telescope has discovered the brightest quasar ever seen in the early Universe. After 20 years of searching, astronomers have identified the ancient quasar with the help of strong gravitational lensing. This unique object provides an insight into the birth of galaxies when the Universe was less than a billion years old.

These are the last moments of a star being devoured by a back hole. 😮
Astronomers using our XMM-Newton space observatory have studied a black hole devouring a star and discovered an exceptionally bright and stable signal that allowed them to determine the black hole’s spin rate.

Let's talk about JUICE today‼️ This not-to-scale artist's impression shows our forthcoming Jupiter Icy Moons Explorer (JUICE) mission, which is planned for launch in 2022 and arrival at Jupiter by 2029.
JUICE will spend at least three years exploring Jupiter and three of the Galilean moons: Ganymede, Europa, and Callisto.
Go to our @instagram Story to learn more about JUICE, its mission and a surprise to celebrate 409 years of the discovery of the Galilean moons by Galileo Galilei. •

This is Ganymede. 🌚
To continue celebrating Galileo Galilei and his discovery of the Galilean moons here's an image taken from NASA's Galileo spacecraft during its first encounter with Ganymede. North is to the top of the picture and the Sun illuminates the surface from the right. The dark areas are the older, more heavily cratered regions and the light areas are younger, tectonically deformed regions. The brownish-gray colour is due to mixtures of rocky materials and ice. Bright spots are geologically recent impact craters and their ejecta. The finest details that can be discerned in this picture are about 13.4 km across.
