Cloudy vision
This #HubbleFriday features CB 130-3, an object known as a “dense core.” This compact clump of gas and dust is the birthplace of stars!
As the core collapses, its dense mass reaches the temperature required to spark hydrogen fusion, creating a new star. Embedded within CB 130-3 is a compact object that is on the brink of becoming a star itself.
CB 130-3 is located in the constellation Serpens about 650 light-years from Earth.
Image description: The image shows an irregularly shaped bright orange object composed of dense gas and dust, which appears darker and more compact at the center. This dense cloud, called CB 130-3, is outlined by thinner gas and dust in light shades of blue. The background shows a multitude of bright stars against a black background.

Seeing quintuple!
In this video, four dots of light seemingly surround a pair of dots in the middle. The middle pair is two giant galaxies. The outer four dots (and a fifth in the very center that is hard to make out) are actually images of the same quasar, an extremely luminous object created when gas and dust fall into a supermassive black hole and emit electromagnetic radiation.
The quasar, known as 2M1310-1714, appears as five points due to gravitational lensing, a phenomenon where an enormous mass (like this galaxy pair) warps the fabric of space, causing light (traveling here from the quasar, through the galaxy pair) to bend around the mass. On Earth, we observe multiple, magnified images of the quasar, which is actually located far beyond the galaxy pair.

With time, a new star will form
@esawebb has revealed the once-hidden features of the protostar within the dark cloud L1527, providing insight into the formation of a new star. These blazing clouds within the Taurus star-forming region are only visible in infrared light, making it an ideal target for Webb.
The protostar itself is hidden from view within the ‘neck’ of this hourglass shape. An edge-on protoplanetary disc is seen as a dark line across the middle of the neck. Light from the protostar leaks above and below this disc, illuminating cavities within the surrounding gas and dust.
The region’s most prevalent features, the blue and orange clouds, outline cavities created as material shoots away from the protostar and collides with the surrounding matter. The colours themselves are due to layers of dust between Webb and the clouds. The blue areas are where the dust is thinnest. The thicker the layer of dust, the less blue light is able to escape, creating pockets of orange.
Webb also reveals filaments of molecular hydrogen that have been shocked as the protostar ejects material away from it. Shocks and turbulence inhibit the formation of new stars, which would otherwise form throughout the cloud. As a result, the protostar dominates the space, taking much of the material for itself.
Despite the chaos that L1527 is causing, it’s only about 100 000 years old — a relatively young body. Given its age and its brightness in far-infrared light, L1527 is considered a class 0 protostar, the earliest stage of star formation. Protostars like these, which are still cocooned in a dark cloud of dust and gas, have a long way to go before they become fully-fledged stars. L1527 doesn’t generate its own energy through the nuclear fusion of hydrogen yet, an essential characteristic of stars. Its shape, while mostly spherical, is also unstable, taking the form of a small, hot, and puffy clump of gas somewhere between 20% and 40% of the mass of our Sun.

Twinkle, twinkle many stars…
This sparkling new #StarrySights Hubble image features NGC 2660, an open star cluster located in the constellation Vela. Unlike in globular clusters, the individual stars of an open cluster can be distinguished, as seen clearly in this view.
The spikes surrounding the stars in this image are called “diffraction spikes” and result from bright points of light reflecting off of Hubble’s secondary mirror support.
Image description: Several stars with pointed diffraction spikes gleam in shades of white, orange, and blue against a black backdrop of space.

Artemis I highlights
View of our European Service Module that is powering NASA's Orion spacecraft, pointing at our planet and the Moon, taken on the 13th day of flight for the Artemis I mission at 22:06 CET, 28 November 2022. It shows Orion and the European Service Module halfway through the Artemis I mission near its maximum distance from Earth, at 432210 km from our home planet and over 64 000 km from the Moon. Seen from the spacecraft our planet had just passed behind the Moon when this photo was taken, as Orion was in lunar orbit.
On flight day six of the Artemis I mission, Orion used its optical navigation camera to snap this black-and-white photo of the Moon.
A portion of the far side of the Moon looms large just beyond the Orion spacecraft in this image taken on the sixth day of the Artemis I mission by a camera on the tip of one of Orion’s solar arrays.
On the sixth day of the Artemis I mission, Orion’s optical navigation camera captured black-and-white images of craters on the Moon below.
A camera mounted on one of Orion’s solar array wings captures Earth as it sets behind the Moon ahead of the outbound powered flyby, an approximately 2 minute, 30 second burn (speeded up in this video) that committed the spacecraft to a distant retrograde orbit.
Update: The Orion capsule left distant lunar orbit at 22:53 CET on 1 December and is on its return journey home. The spacecraft completed the distant retrograde departure burn, firing the European Service Module’s main engine for 105 seconds to set the spacecraft on course for a close lunar flyby as it returns to Earth.

The Flame Nebula is located about 1,400 light-years from Earth in the constellation Orion. More than 15 light-years across, this notable nebula contains a cluster of hundreds of young stars near its center.

Today Chandra is studying the supermassive #BlackHole in the core of NGC 1022. This barred spiral galaxy is roughly 1/3 the size of our Milky Way Galaxy and it's located about 70 million light-years from Earth in the constellation Cetus.

Instead of digging deep underground to find #fossils & ruins, astronomers look up to the #night sky. The oldest fossils found on Earth are roughly 3.5 billion years old. The light from the Musket Ball Cluster took a staggering ~5.1 billion years to reach us!
