Distribution of calcium around the supernova remnant SNR 0509-67.5
This image shows the distribution of calcium in the supernova remnant SNR 0509-67.5. The data were captured with the Multi-Unit Spectroscopic Explorer (MUSE) instrument at ESO’s Very Large Telescope (VLT). The overlaid curves outline two concentric shells of calcium that were ejected in two...
This image, taken with ESO’s Very Large Telescope (VLT), shows the supernova remnant SNR 0509-67.5. These are the expanding remains of a star that exploded hundreds of years ago in a double-detonation – the first photographic evidence that stars can die with two blasts. The data were captured...
A trail of celestial objects stretches across this excerpt from a First Look image captured by NSF–DOE Vera C. Rubin Observatory. The most prominent feature is NGC 4261, the large elliptical galaxy in the top half of the image. In the bottom-left of the image is the lenticular galaxy NGC 4281....
A close-up on two galactic members of the Virgo Cluster as imaged by NSF–DOE Vera C. Rubin Observatory. During its observations Rubin captured a plethora of asteroids zipping across this portion of the night sky, indicated by the tri-colored streaks scattered throughout this image. View a...
A close-up on two galactic members of the Virgo Cluster as imaged by NSF–DOE Vera C. Rubin Observatory. During its observations Rubin captured a plethora of asteroids zipping across this portion of the night sky. The tiny streaks left behind from the asteroids have been removed from this image....
The light that the NASA/ESA Hubble Space Telescope collected to create this Picture of the Week reached the telescope after a journey of 250 million years. Its source was the spiral galaxy UGC 11397, which resides in the constellation Lyra (The Lyre). At first glance, UGC 11397 appears to be an...
This image shows the Sculptor Galaxy in a new light. This false-colour composition shows specific wavelengths of light released by hydrogen, nitrogen, sulphur and oxygen. These elements exist in gas form all over the galaxy, but the mechanisms causing this gas to glow can vary throughout the...
This image shows a detailed, thousand-colour image of the Sculptor Galaxy captured with the MUSE instrument at ESO’s Very Large Telescope (VLT). Regions of pink light are spread throughout this whole galactic snapshot, which come from ionised hydrogen in star-forming regions. These areas have...
This new NASA/ESA/CSA James Webb Space Telescope Picture of the Month features a rare cosmic phenomenon called an Einstein ring. What at first appears to be a single, strangely shaped galaxy is actually two galaxies that are separated by a large distance. The closer foreground galaxy sits at...
This portrait from the NASA/ESA Hubble Space Telescope puts the nearby galaxy NGC 4449 in the spotlight. The galaxy is situated just 12.5 million light-years away in the constellation Canes Venatici (The Hunting Dogs). It is a member of the M94 galaxy group, which is near the Local Group of...
The ominous Chamaeleon I dark cloud, the nearest star-forming region to Earth, is captured in this image taken with the 570-megapixel Department of Energy-fabricated Dark Energy Camera mounted on the U.S. National Science Foundation Víctor M. Blanco 4-meter Telescope at Cerro Tololo...
This serene spiral galaxy hides a cataclysmic past. The galaxy IC 758, shown here in today’s NASA/ESA Hubble Space Telescope Picture of the Week, is situated 60 million light-years away in the constellation Ursa Major. In this Hubble image captured in 2023, IC 758 appears peaceful, its soft...
