The Large Magellanic Cloud Galaxy above ESO Telescope in Chile
This image, taken by European Southern Observatory (ESO) Photo Ambassador Petr Horálek, captures the moment that Yepun (UT4), one of the four 8.2-meter Unit Telescopes comprising ESO’s Very Large Telescope (VLT), shoots a laser beam up into the dark night sky over the Paranal Observatory in Chile.
The laser shown in this image acts as an artificial star, known as a Laser Guide Star. It is used to help astronomers adjust for the blurring and distorting effects of the Earth’s atmosphere. When observing a patch of sky, astronomers set up a laser guide star nearby and measure the tiny fluctuations in its image. The VLT’s adaptive optics system can then use this reference to correct for the changes and distortions in the intervening atmosphere and produce the sharpest images possible in the main observations.
Looming over Yepun is the Large Magellanic Cloud (LMC), a barred spiral galaxy that orbits the Milky Way. A faint white glow marks the location of older stellar populations within the LMC, while the iridescent hues of magenta and blue mark young stellar nurseries.
The LMC, as well as its smaller namesake, the Small Magellanic Cloud (SMC), have been studied many times by ESO telescopes over the years. Its many cosmic delights, including nebulae and star clusters, can be seen in detail due to their proximity, and provide amateur and professional astronomers alike with breathtaking targets for observation.
Shenzhou-18 Crew: Maintenance & Handling Emergencies | China Space Station
China's Shenzhou-18 manned space mission crew have completed various tasks including the station's environmental and equipment maintenance and inspection, in-orbit emergency evacuation, and health monitoring and check more than halfway through their six-month mission aboard the Tiangong space station, lately released footage showed.
China's Shenzhou-18 manned space mission crew have completed various tasks including the station's environmental and equipment maintenance and inspection, in-orbit emergency evacuation, and health monitoring and check More than halfway through their six-month mission aboard the Tiangong space station, lately released footage showed.
The Shenzhou-18 crew, comprising astronauts Ye Guangfu, Li Cong and Li Guangsu, have spent more than 100 days in space since they were aboard in late April.
Last week, the trio installed a lid and replenished water for the urine processing system to facilitate water recycling and reuse inside the space station, according to a footage released by the China Manned Space Agency.
The crew also collected the station's environmental data through microbial sampling and testing on the total organic carbon, the total volatile organic compounds, and the in-cabin thermal environment. Based on these data, ground researchers can make assessment and appraisal of the station's internal environment to ensure the health and safety of astronauts.
In addition, the crew carried out a regular fire alarm drill last week to practice emergency evacuation under various working conditions while quickly putting on the space suit.
They also classified various living materials and materials for scientific experiments, and conducted garbage transfer and stocking, and the assorting and counting of medical supplies to make the space station clean and tidy.
To guarantee that their physical conditions enable them to perform various tasks, they received multiple medical checks, including the noninvasive cardiac function test which is safe, accurate, reliable and quite easy to perform.

Sit back, relax and enjoy this journey to NGC 1850, a cluster of thousands of stars roughly 160,000 light-years away in the Large Magellanic Cloud, a Milky Way neighbor.
Among many stars, this cluster is home to a black hole eleven times as massive as the Sun and to the five-solar-mass star orbiting it. By looking at the star’s orbit, a team of astronomers were able to infer the presence of the black hole, making it the first small black hole outside of our galaxy to be found this way. For this discovery, the team used the Multi Unit Spectroscopic Explorer (MUSE) instrument at the European Southern Observatory’s Very Large Telescope in Chile.

Star Cluster NGC 1850 in Dorado | ESO's Very Large Telescope & Hubble
This image shows NGC 1850, a cluster of thousands of stars roughly 160,000 light-years away in the Large Magellanic Cloud, a Milky Way neighbor. The reddish filaments surrounding the cluster, made of vast clouds of hydrogen, are believed to be the remnants of supernova explosions.
The image is an overlay of observations conducted in visible light with the European Southern Observatory’s Very Large Telescope (VLT) and NASA/European Space Agency’s Hubble Space Telescope (HST). The VLT captured the wide field of the image and the filaments, while the central cluster was imaged by the HST.

Star Cluster NGC 1850 in Dorado | NASA's Chandra X-ray Observatory
NGC 1850 is a bright, double star cluster that lies in the Large Magellanic Cloud—a small neighbor galaxy to the Milky Way. It contains a black hole with a mass of about eleven Suns, and a companion star. No clear detection of X-rays with Chandra implies that the black hole is not quickly pulling material away from its companion. This composite image displays x-rays from Chandra (magenta); optical light from the Hubble Space Telescope (red, yellow, green, cyan, blue); infrared light from the Spitzer Space Telescope (red).
This image features a double star cluster, a blue-tinted cloud, and several neon purple dots. The bright, golden stars in the larger cluster fill the upper center of the image. The other cluster is much smaller and coincides with one of the neon purple circles located slightly above and to the right of the image’s center. This and the other purple circles are X-ray sources detected with Chandra. To our left of the combined cluster is a vertical streak of blue-tinted cloud.
Barred Spiral Galaxy NGC 1672 in Dorado | Victor Blanco Telescope
The arms of the barred spiral galaxy NGC 1672 sweep across this image captured by the Víctor M. Blanco 4-meter Telescope at Cerro Tololo Inter-American Observatory (CTIO), a Program of the National Science Foundation’s NOIRLab. NGC 1672 is a celestial mystery, as it is difficult to define its galactic activity. A barred spiral galaxy has a central bar-shaped structure composed of stars.
Distance:50 million light years
The nucleus is surrounded by a ring of hot gas filled with individual point sources of X-ray light, in other words bright, newly formed stars. However, the luminous nucleus of NGC 1672 itself shines brightly in types of light ranging from X-ray to infrared. Known as a Seyfert Type 2 nucleus, it is an example of a specific type of active galactic nucleus (AGN) and likely a supermassive black hole. Fragile young stars and a destructive AGN should not necessarily be so close together, and their proximity in this galaxy creates a conundrum. Galaxies like NGC 1672 can open up new pathways to understanding the activities and behaviors of galaxies, including their long-term evolution.
Data for this image were collected using the Dark Energy Camera on the 4-meter Víctor M. Blanco Telescope for the Dark Energy Survey. It has mapped millions of galaxies to determine the nature of dark energy. The analysis of data from the Dark Energy Survey is supported by the U.S. Department of Energy and the National Science Foundation, and the Dark Energy Camera science archive is curated by the Community Science and Data Center at NOIRLab.
The 4-meter Víctor M. Blanco Telescope was commissioned in 1974. It is a near twin of the Mayall 4-meter telescope on Kitt Peak. In 1995 it was dedicated and named in honor of Puerto Rican astronomer Víctor Manuel Blanco. It is also part of the Dark Energy Survey (DES), a visible and near-infrared survey that aims to probe the dynamics of the expansion of the Universe.

China Develops Reusable Commercial Rockets to Improve Launch Capabilities
China has been working to improve its rocket launch capabilities by sending low-cost rockets into space with a focus on developing reusable rockets.
The Lijian-2 carrier rocket, the first liquid-propellant rocket developed by a high-tech enterprise in Beijing, is scheduled to be launched next year for the first time with the first stage and the booster of the rocket recycled by 2028.
"It's highly reliable and developed rapidly, with a payload capacity of around eight tonnes. It's mainly used to launch satellite groups for the construction of the low-orbit Internet constellation, and low-cost cargo ships," said Shi Xiaoning, vice president of Beijing CAS Space Technology Co., Ltd.
He said the construction of large-scale satellite constellation puts forward higher requirements on the costs and production capacity of rockets, and they have conducted a number of recycling tests.
"To recycle rockets is the major way to reduce the demand for rocket production capacity as it's impossible for us to build production lines without limits. So we recycle the big stuff, which is the best way to improve the launch capacity," Shi said.
Another commercial rocket company LandSpace in Beijing is also working on the research on reusable rockets.
The vertical return technology of Zhuque-3, a reusable rocket developed by the company, has successfully completed its first flight test at the beginning of this year.
The flight test verified the vertical recovery of a rocket at low altitude and low speed, matching between the control system and engine thrust adjustment performance, and the rocket vertical recovery's guidance and control algorithm, according to LandSpace.
"We have made a rough assessment before. It is preliminarily estimated that if the first stage of the rocket can be reused for 20 times, the entire cost can be reduced by more than half. Taking into account the expense on test, maintenance and fuel after recycling, we can save more than 60 percent of the costs," said Dai Zheng, commander in chief of China's reusable rocket Zhuque-3.

Farewell to NEOWISE: NASA’s Asteroid-Hunting Telescope | JPL
NASA's NEOWISE mission ended on Aug. 8, 2024, after more than a decade of discovering and tracking near-Earth objects—asteroids and comets that come close to Earth’s orbit. The mission team gathered at the agency’s Jet Propulsion Laboratory in Southern California as the spacecraft received its final command to turn off its transmitter, concluding the mission.
Launched in 2009 as Wide-field Infrared Survey Explorer (WISE), the space telescope completed its primary mission to conduct an all-sky survey in the infrared spectrum. The spacecraft was put into hibernation in 2011, then re-awakened in 2013 for a second career as NEOWISE (Near-Earth Object Wide-field Infrared Survey Explorer).
NEOWISE is expected to re-enter the atmosphere and safely burn up in late 2024.
Views of Galaxy Messier 106 by Hubble & Webb Space Telescopes
This collage features three views of Messier 106, also known as NGC 4258. The first two images show the target in visible light as seen by the Kitt Peak National Observatory's Mayall Telescope and the NASA/European Space Agency Hubble Space Telescope. The image on the right is a new image from the NASA/European Space Agency/Canadian Space Agency James Webb Space Telescope in the infrared.
This is a nearby spiral galaxy that resides roughly 23 million light-years away in the constellation Canes Venatici, practically a neighbor by cosmic standards. Messier 106 is one of the brightest and nearest spiral galaxies to our own and two supernovae have been observed in this galaxy in 1981 and 2014.
Image Description: A graphic with three images. The leftmost image shows a spiral galaxy in full on a dark background, seen in visible light by a ground-based telescope. A box over an area in the center of the galaxy links by a pullout to the two right images. They both display this area larger and in more detail. The center image shows it in visible light by the Hubble Space Telescope, the right in infrared light by the James Webb Space Telescope.

Pan of Galaxy Messier 106 | James Webb Space Telescope
Featured in this new image from the NASA/European Space Agency/Canadian Space Agency James Webb Space Telescope is Messier 106, also known as NGC 4258. This is a nearby spiral galaxy that resides roughly 23 million light-years away in the constellation Canes Venatici, practically a neighbor by cosmic standards. Messier 106 is one of the brightest and nearest spiral galaxies to our own and two supernovae have been observed in this galaxy in 1981 and 2014.
At its heart, as in most spiral galaxies, is a supermassive black hole, but this one is particularly active. Unlike the black hole at the center of the Milky Way that pulls in wisps of gas only occasionally, Messier 106’s black hole is actively gobbling up material. As the gas spirals towards the black hole, it heats up and emits powerful radiation.
This image was captured with Webb’s Near-InfraRed Camera (NIRCam). The observation was taken as part of a dedicated program to study the galaxy’s active galactic nucleus, the galaxy’s bright central region that is dominated by the light emitted by dust and gas as it falls into the black hole. The blue regions in this image reflect stellar distribution throughout the central region of the galaxy. The orange regions indicate warmer dust and the stronger red hues represent colder dust. The teal, green and yellow tones near the center of the image depict varying gas distributions throughout the region.
The galaxy has a remarkable feature—it is known to have two ‘anomalous’ extra arms visible in radio and X-ray wavelengths, rather than in the visible. Unlike the normal arms, these are composed of hot gas instead of stars. Astronomers believe these extra arms result from the black hole’s activity, a feedback effect seen in other galaxies as well. They are likely caused by outflowing material produced by the violent churning of gas around the black hole, creating a phenomenon analogous to a wave crashing up out of the ocean when it hits a rock near the shore.
Despite carrying his name, Messier 106 was neither discovered nor cataloged by the renowned 18th century astronomer Charles Messier. Discovered by his assistant, Pierre Méchain, the galaxy was never added to the catalogue in his lifetime. Along with six other objects discovered but not logged by the pair, Messier 106 was posthumously added to the Messier catalogue in the 20th century.
Image Description: The central region of a spiral galaxy. Its core is a small bright point radiating bright, bluish-white light over the scene. The white light is diffuse and many point-like stars in the galaxy (and even background galaxies) can be seen through it. The galaxy’s arms can be seen as broad, swirling streaks of glowing gas and dust, colored red and orange. Two additional arms are revealed in green.
