Today Chandra is studying a black hole in Ursa Major, the Great Bear. Nearby in the sky is NGC 2985, a #galaxy with tightly wound spiral arms that are sprinkled with knots of blue #stars. Located about 70 million light-years from Earth — what a wonderful whorl

Gravitational lensing provides us with a way of probing extremely distant galaxies in ways that would otherwise be impossible even with the most powerful telescopes. Nicknamed the "Cheshire Cat," this #smile is the result of mass distorting the faraway light of multiple galaxies.

What does the future of space exploration look like?
Our new ambitious Terrae Novae programme brings Earth orbit, the Moon and Mars into a single project to lead Europe’s human journey into the Solar System using robots as precursors and scouts.
Terrae Novae will inspire Europeans and boost the competitiveness of European industry as well as enable future space missions and train the astronauts of tomorrow.
The technology used in space exploration benefits all citizens with its strong innovation and growth potential that help tackle today’s grand challenges including energy and climate, sustainability and healthcare.
As we travel beyond Earth, visiting new destinations and discovering new things, we will always do so ethically and responsibly.
The ESA Council at Ministerial level, CM22, taking place in Paris, France, on 22 and 23 November 2022, will be a time for critical decisions. ESA’s Member States, Associate States and Cooperating States must together strengthen Europe’s space sector and ensure it continues to serve European citizens.

Forward to the Moon
At 07:47 CET (01:47 local time), the Artemis I mission started its voyage to the Moon as NASA's new Moon rocket lifted off from nasakennedy in Florida, USA, and put the Orion spacecraft and its European Service Module into Earth orbit.
The spacecraft spent two hours circling Earth before being boosted towards the Moon. The spacecraft is in good health and all systems are operating as expected as it now begins its ten-day cruise to our natural satellite.
The Artemis I mission will see Orion and the European Service Module on a 26-day mission to the Moon and back. It will spend around a week orbiting the Moon, with the European Service Module firing its 33 engines to keep the spacecraft on course and in the best position to receive sunlight on the four 7-m long solar arrays.
The European Service Module also keeps the spacecraft operating at correct temperatures and holds all the fuel tanks for the engines. In future Artemis missions, the European Service Module will deliver air and water to the astronauts working in the Orion’s crew module.
Throughout the mission, personnel based at our technical heart in The Netherlands are on-hand to provide expertise and in-depth knowledge of the European Service Module to the main mission control at nasajohnson, in Houston, USA.
Artemis I will end with a splashdown in the Pacific Ocean, off the coast of California, USA. The European Service Module separates and burns up harmlessly in the atmosphere shortly before the Orion crew module splashes down.

Combining Webb’s infrared & Chandra's X-ray views demonstrates the power of telescope teamwork.
Stephan's Quintet: 4 galaxies in Stephan’s Quintet are undergoing an intricate gravitational dance. (The 5th galaxy on the left is at a different distance!) Webb’s image (red, orange, yellow, green, blue) features never-seen-before details, like sweeping tails of gas and star formation bursts. Chandra (light blue) uncovers a shock wave that heats gas to tens of millions of degrees, as one galaxy passes through the others at around 2 million miles per hour. This image also includes infrared data from Spitzer (red, green, blue), now retired.
Cartwheel Galaxy: The Cartwheel Galaxy got its shape from a collision with a smaller galaxy (outside the field) about 100 million years ago. X-rays seen by Chandra (blue and purple) come from superheated gas, exploded stars, and neutron stars and black holes pulling material from companion stars. Webb’s infrared view (red, orange, yellow, green, blue) shows the Cartwheel Galaxy plus 2 smaller companions (not part of the collision) against a backdrop of many more distant galaxies.
Deep Field: Webb shows how galaxy cluster SMACS J0723, located ~4.2 billion light-years away, contains hundreds of galaxies. Galaxy clusters are filled with vast reservoirs of superheated gas seen only in X-ray light. Chandra data (blue) reveals gas with temperatures of tens of millions of degrees, possessing a total mass about 100 trillion times that of the Sun. Invisible dark matter forms an even larger fraction of the cluster’s total mass.
Carina Nebula: Chandra’s data (pink) reveals over a dozen X-ray sources. These are mostly 1-2 million year old stars (very young for stars!) located in the outer region of a star cluster in the Carina Nebula. Young stars are much brighter in X-rays than old stars. The X-ray emission in the image’s top half likely comes from hot gas from the nebula’s 3 hottest, most massive stars, outside Webb’s view. Webb’s image uses: red, orange, yellow, green, cyan, and blue.

Today Chandra is studying a #supernova in the constellation Canes Venatici, "the hunting dogs." Nearby in the #sky is galaxy NGC 5033. The supermassive #BlackHole at this galaxy's core is devouring stars, dust, and any other matter that gets too close to it — radiating light in many different wavelengths.

IC 1396A is situated about 2,800 light-years from Earth in the constellation Cepheus. Radiation & winds from massive stars are impacting clouds of cool gas, triggering the formation of new generations of stars.
A #star
is born when a cloud of gas and dust collapses to the point where the material in the center of the clump is so dense and hot that the nuclear fusion of hydrogen nuclei into helium nuclei can occur.

This delicate tapestry of X-ray light is the remnant of a supernova explosion that would have been witnessed on Earth about 3,700 years ago. Known as "Puppis A," it spans more than 100 light-years from side to side and it's located about 7,000 light years from Earth. Happy #FirstDayOfFall
