The lenticular galaxy NGC 6684 bathes this image from the NASA/ESA Hubble Space Telescope in a pale light. Captured with Hubble’s Advanced Camera for Surveys, this galaxy is around 44 million light-years from Earth in the constellation Pavo. Pavo – the Latin name for peacock – is a constellation in the southern sky and one of four constellations collectively known as the Southern Birds.

JWST/NIRcam composite image of the Ring Nebula. The images clearly show the main ring, surrounded by a faint halo and with many delicate structures. The interior of the ring is filled with hot gas. The star which ejected all this material is visible at the very centre. It is extremely hot, with a temperature in excess of 100,000 degrees. The nebula was ejected only about 4000 years ago. Technical details: The image was obtained with JWST's NIRCam instrument on August 4, 2022. Images in three different filters were combined to create this composite image: F212N (blue); F300M (green); and F335M (red).

Curiosity rover battles up a 23-degree slope in its exploration of Mars

The Curiosity rover is slowing making its way up Mount Sharp, a 3-mile-tall mountain on Mars. But heaving up a mountain can be tricky for a little rover.
A coronal mass ejection as seen by SOHO on 28 October 2021. This event is an example of a rare ‘ground level enhancement’. During these events, particles from the Sun are energetic enough to pass through the magnetic bubble that surrounds Earth and protects us from less energetic solar outbursts. This was only the 73rd ground level enhancement since records began in the 1940s, and none have been recorded since.

A solar eruption was detected on Earth, the moon, and even Mars

Scientists recently reported on a solar event that was detectable not only on Earth, but also on the moon and Mars.
Webb’s infrared image of the galaxy cluster El Gordo (“the Fat One”) reveals hundreds of galaxies, some never before seen at this level of detail. El Gordo acts as a gravitational lens, distorting and magnifying the light from distant background galaxies. Two of the most prominent features in the image include the Thin One, located just below and left of the image center, and the Fishhook, a red swoosh at upper right. Both are lensed background galaxies.

James Webb image shows the majesty of the most massive known galaxy cluster

A recent image from the James Webb Space Telescope shows the most massive galaxy cluster we know of, one so large that it is nicknamed El Gordo, or the fat one.
Euclid’s Near-Infrared Spectrometer and Photometer (NISP) instrument is dedicated to measuring the amount of light that galaxies emit at each wavelength. It will image the sky in infrared light (900–2000 nm) to measuring the brightness and intensity of light. This image was taken during commissioning of Euclid to check that the focused instrument worked as expected. This is a raw image taken using NISP’s ‘Y’ filter. Because it is largely unprocessed, some unwanted artefacts remain – for example the cosmic rays that shoot straight across, seen especially in the VIS image. The Euclid Consortium will ultimately turn the longer-exposed survey observations into science-ready images that are artefact-free, more detailed, and razor sharp.

The spiral galaxy NGC 1532, also known as Haley’s Coronet, is caught in a lopsided tug of war with its smaller neighbor, the dwarf galaxy NGC 1531. The image — taken by the US Department of Energy’s (DOE) Dark Energy Camera mounted on the National Science Foundation’s (NSF) Víctor M. Blanco 4-meter Telescope at Cerro Tololo Inter-American Observatory in Chile, a Program of NSF’s NOIRLab — captures the mutual gravitational influences of a massive- and dwarf-galaxy merger.

A billowing pair of nearly symmetrical loops of dust and gas mark the death throes of an ancient red-giant star, as captured by Gemini South, one half of the International Gemini Observatory, operated by NSF’s NOIRLab. The resulting structure, said to resemble an old style of English jug, is a rarely seen bipolar reflection nebula. Evidence suggests that this object formed by the interactions between the dying red giant and a now-shredded companion star. The image was obtained by NOIRLab’s Communication, Education & Engagement team as part of the NOIRLab Legacy Imaging Program.

The first anniversary image from the NASA/ESA/CSA James Webb Space Telescope displays star birth like it’s never been seen before, full of detailed, impressionistic texture. The subject is the Rho Ophiuchi cloud complex, the closest star-forming region to Earth. It is a relatively small, quiet stellar nursery, but you’d never know it from Webb’s chaotic close-up. Jets bursting from young stars crisscross the image, impacting the surrounding interstellar gas and lighting up molecular hydrogen, shown in red. Some stars display the telltale shadow of a circumstellar disc, the makings of future planetary systems.
