In the upper part of this Hubble image, the light from distant galaxies has been smeared and twisted into odd shapes, arcs, and streaks. This phenomenon indicates the presence of a massive galaxy cluster, SDSS J0150+2725, which is bending the light coming from the galaxies behind it with its monstrous gravitational influence.

Gaia’s all-sky view of our Milky Way Galaxy and neighboring galaxies, based on measurements of nearly 1.7 billion stars. Brighter regions indicate denser concentrations of especially bright stars, while darker regions correspond to patches of the sky where fewer bright stars are observed. The color representation is obtained by combining the total amount of light with the amount of blue and red light recorded by Gaia in each patch of the sky. The bright horizontal structure that dominates the image is the Galactic plane, the flattened disc that hosts most of the stars in our home Galaxy. In the middle of the image, the Galactic center appears vivid and teeming with stars. Darker regions across the Galactic plane correspond to foreground clouds of interstellar gas and dust, which absorb the light of stars located further away, behind the clouds. Many of these conceal stellar nurseries where new generations of stars are being born. Sprinkled across the image are also many globular and open clusters -- groupings of stars held together by their mutual gravity, as well as entire galaxies beyond our own. The two bright objects in the lower right of the image are the Large and Small Magellanic Clouds, two dwarf galaxies orbiting the Milky Way. In small areas of the image where no color information was available -- to the lower left of the Galactic center, to the upper left of the Small Magellanic Cloud, and in the top portion of the map -- an equivalent grayscale value was assigned.

This Hubble image shows the galaxy cluster MACS J1149.5+223, whose light has taken over 5 billion years to reach us. Highlighted is the position where the Icarus star appeared -- its image magnified by a factor 2,000 by gravitational microlensing. The spiral galaxy in which the star is located can be seen three times on the sky -- multiplied by strong gravitational lensing. Image credit: NASA / ESA / S.
