This image shows the supernova remnant 1E 0102.2-7219 (E0102 for short). It contains an isolated neutron star, which appears as a small blue point source surrounded by a compact ring of gas, which glows a bright, deep red. Together, the red ring and point source act like a celestial bull's eye. Beyond this red ring lies a larger structure, which appears as a large blue and purple shell or ring. This shell is more diffuse than the red ring, with soft edges that spread outward, giving the impression of a bright cloud expanding into space. The shades of blue and purple vary in intensity, with brighter areas near the center fading into darker areas at the edges, suggesting the motion of the shock wave from the supernova remnant. Visible-light data from Hubble add further detail, depicted in shades of dark red and green. In particular, a green filamentary structure, representing oxygen-rich debris ejected by the star's explosion, intertwines with the red ring and the blue-violet shell. These green filaments appear as thin ribbons or veins, adding intricate texture and a sense of depth to the image. The less prominent dark red blends in some areas with the bright red of MUSE, creating a layered effect that enriches the scene. The background of the image is mostly black, representing the vacuum of deep space, with subtle shades of dark blue in regions where the X-ray emission is weakest. The contrast between these elements creates a dramatic and dynamic image, with the neutron star appearing as a bright, solitary point, surrounded by concentric structures that appear to pulsate with cosmic energy.

This striking composite image, made combining data from Chandra (X-ray light) & VLT MUSE (optical light) & Hubble, shows a supernova remnant with a lonely neutron star.

This is literally what is about to happen to the U.S. scientific space fleet. If the President's budget is enacted by Congress, nearly all functioning heliophysics space missions will be canceled or severely cut, squandering decades of work and ceding the U.S.A.'s hard-won space leadership. 🧪🛰️🔭☀️

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.
#ESAGaia has changed our impression of the Milky Way.
The mission has shown us that it has more than two spiral arms and that they are less prominent than we previously thought.

Chien-Shiung Wu, who obtained experimental proof of parity violation in weak nuclear decay, was born #OTD in 1912.
Her 1956 experiment involving the decay of Cobalt-60 confirmed that the weak interaction does not respect what many had assumed was a fundamental symmetry of nature. 🧪 👩🔬 ⚛️

Fluffy tan-colored nebula clouds, with rust-colored highlights, surround a black central area. Within that area, the focal point of the image is one large yellow star with eight long thin points. To the right of this star is a bright star cluster in an oval shape. The stars within the cluster look like tiny pale blue sparkles. The cluster is more densely packed at its core and scatters outward. Towards the bottom of the image, multiple arms appear to spiral out of a cloudy tan knob. Taken together, the structures resemble a spider or a squid. Other blue and yellow eight-pointed stars, as well as distant galaxies, are dotted throughout the image.

People should lift each other up and cheer each other on, not try to outdo each other. The sky would be terribly dark with only one star.
This image of the Ring Nebula, taken by Webb’s Near-Infrared Camera, appears as a distorted doughnut. The nebula’s inner cavity hosts shades of blue and green, while the detailed ring transitions through shades of orange in the inner regions and pink in the outer region. The ring’s inner region has distinct filament elements. Stars litter the scene, with a particularly prominent star with 8 long spikes in the top right corner.
Colorful clouds of gas and dust crowd the image. Deep red and orange clouds surround the image's edges, with some violet in the upper left portion. Near the left middle, a region of teal and yellow shines.
A star cluster is shown inside a large nebula of many-coloured gas and dust. The material forms dark ridges and peaks of gas and dust surrounding the cluster, lit on the inner side, while layers of diffuse, translucent clouds blanket over them. Around and within the gas, a huge number of distant galaxies can be seen, some quite large, as well as a few stars nearer to us which are very large and bright.
A colorful, glowing nebula that reaches beyond the top and bottom of the image. This translucent cloud of gas holds wispy and thin filaments with hard edges in some places, and puffy and opaque in others. Blue, red, and yellow colors mix together, showing light emitted by different types of atoms in the hot gas. Scattered across the colorful nebula are bright and point-like foreground and background stars. The background is black.
the universe wishes you a very happy pride month 🏳️🌈🌌

It lies inside the Tarantula Nebula in the Large Magellanic Cloud, some 160,000 light years away. I processed Hubble data to produce this image, the observation having been made in October 2020.
