Into the Heart of Spiral Galaxy NGC 1232 in Eridanus | ESO

Into the Heart of Spiral Galaxy NGC 1232 in Eridanus | ESO


This spectacular image of the large spiral galaxy NGC 1232 was obtained on September 21, 1998, during a period of good observing conditions. It is based on three exposures in ultra-violet, blue and red light, respectively. The colors of the different regions are well visible. The central areas contain older stars of reddish color, while the spiral arms are populated by young, blue stars and many star-forming regions. Note the distorted companion galaxy on the left side, shaped like the greek letter "theta". NGC 1232 was discovered by German-British astronomer William Herschel on October 20, 1784.

NGC 1232 is located 20º south of the celestial equator, in the constellation Eridanus (The River). The distance is about 60 million light-years, but the excellent optical quality of the Very Large Telescope (VLT) and FORS allows us to see an incredible wealth of details. FORS is the visual and near UV FOcal Reducer and low dispersion Spectrograph for the VLT. At the indicated distance, the edge of the field shown corresponds to about 200,000 light-years, or about twice the size of the Milky Way galaxy.

The image is a composite of three images taken behind three different filters: U (360 nm; 10 min), B (420 nm; 6 min) and R (600 nm; 2:30 min) during a period of 0.7 arcsec seeing. The field shown measures 6.8 x 6.8 arcmin. North is up; East is to the left.

China Shenzhou-18 Crew Rocket Rollout to Launchpad | China Space Station

China Shenzhou-18 Crew Rocket Rollout to Launchpad | China Space Station









The combination of the Shenzhou-18 spaceship and a Long March-2F Y18 carrier rocket has been vertically transferred to the launching area at the Jiuquan Satellite Launch Center in northwest China on Wednesday morning, April 17, 2024. Shenzhou-18 will transport the seventh crew of three astronauts to the China Space Station and replace the Shenzhou-17 crew currently onboard.

Weighing over 40 tons, with a total height of nearly 60 meters, the combination has four support points distributed along the circumference of the rocket's core stage that measures only 3.35 meters in diameter. The total weight of the combination and the launch platform is nearly 800 tons.

According to the China Manned Space Agency (CMSA), the facilities and equipment at the launch site are in good condition, and various pre-launch function checks and joint tests will be carried out as planned. The crewed spaceship will be launched at an appropriate time in the near future, said the CMSA.

Shenzhou-17 Crew:

Hongbo Tang (Commander)

Shengjie Tang (Mission Specialist)

Xinlin Jiang (Mission Specialist)

The Shenzhou-18 crew members will be announced shortly before launch.

"This will be the first manned mission conducted in April since we started building the space station. Considering the characteristics of high winds and dust during this season, we have conducted statistical analysis of meteorological data over the past 30 years in the launch site, and formulated targeted preventive measures and response strategies. Meanwhile, we have updated power supply system of certain facilities, strengthened equipment operation assessments and status checks, and organized interdisciplinary collaborative training and emergency drills. We have also improved the comprehensive situational awareness and critical information collection and dissemination capabilities of the launch site, optimized our product testing projects and timing, therefore, further improving the site's ability to handle continuous missions," said Wang Xuewu, deputy director of Jiuquan Satellite Launch Center.

A Silent Watcher of The Earth's Southern Hemisphere

A Silent Watcher of The Earth's Southern Hemisphere


The top half of the image is taken up by the night sky, dotted with thousands of tiny white stars. The sky goes from darker blue at the top to green and orange at the horizon with faint pink patches in between. In the top third of the image are two white-bluish cloud-like structures and a thin white streak. The steely circular dish of a telescope in the center of the image reflects colors of the sky. In the foreground we see the rocks and grass on the ground in front of the telescope; behind it, a mountain range in shades of violet and blue stretches into the distance.

This picture shows the stunning night sky over the Swedish–ESO Submillimeter Telescope (SEST) telescope at the European Southern Observatory’s La Silla Observatory in Chile. Until its retirement in 2003, SEST used its 15-meter main dish to observe the cold gas clouds where stars form. Now the telescope, perching at 2,375 meters altitude, watches silently over the landscape of the Atacama Desert.

While SEST stands in one of the darkest places on the planet, the sky itself is not completely black— rather the opposite! Here, besides thousands of stars, the picture features shades of red and green across the sky—an atmospheric phenomenon called airglow. In the bottom-left part of the sky we can see a portion of the band of the Milky Way, our home galaxy, and in the top half, two cloud-like structures that look like galactic fireworks. These are the Large and Small Magellanic Clouds, two dwarf galaxies that orbit the Milky Way, trapped by its gravity. They are visible to the naked eye and have been known since ancient times to indigenous peoples in the Southern Hemisphere,. They often compared them with water ponds or even animals like pigs or tapirs.

In this picture, there is even a shooting star coming by to say hello to SEST. Can you spot it in the sky?

NASA Apollo 9 Official Mission Patch (1969)

The primary objective of Apollo 9 during its flight March 3-13, 1969 was an Earth-orbital engineering test of the first crewed lunar module, or LM. Other prime objectives included an overall checkout of launch vehicle and spacecraft systems, the crew, and procedures. This was done by performing an integrated series of flight tasks with the command module, or CM, the service module, or SM, the joined command and service module, or CSM, the LM and S-IVB stage while they were linked in launch or various docked configurations, and while they were flying independently. The LM was to be tested as a self-sufficient spacecraft, and was also to perform active rendezvous and docking maneuvers paralleling those scheduled for the following Apollo 10 lunar-orbit mission.

Apollo 9 Crew

Commander James McDivitt 

Command Module Pilot David Scott

Lunar Module Pilot Russell Schweickart

The flight plan’s top priority was the CSM and LM rendezvous and docking. This was performed twice—once while the LM was still attached to the S-IVB, and again when the LM was active. Further goals included internal crew transfer from the docked CSM to the LM; special tests of the LM’s support systems; crew procedures; and tests of flight equipment and the extravehicular activity, or EVA, mobility unit. The crew also configured the LM to support a two-hour EVA, and simulated an LM crew rescue, which was the only planned EVA from the LM before an actual lunar landing.

The LM descent and ascent engines fired on orbital change patterns to simulate a lunar-orbit rendezvous and backup abort procedures. The CSM service propulsion system, or SPS, fired five times, including a simulation of an active rendezvous to rescue an LM that had become inactivate.

All prime mission objectives were met. All major spacecraft systems were successfully demonstrated. The few off-nominal conditions that developed did not affect achievement of the major goals.

Rare Sighting of ‘Doomed’ SOHO Sungrazing Comet: Solar Eclipse 2024

Rare Sighting of ‘Doomed’ SOHO Sungrazing Comet: Solar Eclipse 2024


Early on April 8, 2024, a citizen scientist found a comet in images from the European Space Agency/NASA Solar and Heliospheric Observatory (SOHO). It follows the recent discovery of SOHO’s 5000th comet. However, this one—named Comet SOHO-5008—was special for another reason.

Karl Battams, manager of the SOHO Sungrazer Project, predicted that comet SOHO-5008 would be visible during the total solar eclipse. It was due to plunge parts of the United States and Mexico into darkness later that same day.

Petr Horálek, from the Institute of Physics in Opava (Czechia), was in Mexico for the eclipse. The clouds cleared and Petr took this beautiful shot of the Sun’s awe-inspiring corona. To the lower left of the Sun, Comet SOHO-5008 is visible.

Soon after Petr captured the comet on camera, it met its demise, coming so close to the Sun that it disintegrated.

Observations of these ‘sungrazing’ comets from the ground are extremely rare, and this sighting was only possible thanks to the total solar eclipse.

The image is a composite of 100 frames, with the wide corona imaged at a focal length of 200 mm (exposure time from 1/4000 to 2 seconds) and the inner corona imaged at a focal length of 1100 mm (exposure time from 1/500 to 4 seconds).

SOHO’s prowess as a comet-hunter was unplanned, but turned out to be an unexpected success. With its clear view of the Sun’s surroundings, SOHO can easily spot sungrazing comets. This has made it the most prolific discoverer of comets in astronomical history.

SOHO is a cooperative effort between the European Space Agency (ESA) and NASA. Mission control is based at NASA’s Goddard Space Flight Center (GSFC) in Greenbelt, Maryland. SOHO’s Large Angle and Spectrometric Coronagraph Experiment (LASCO), the instrument that provides most of the comet imagery, was built by an international consortium, led by the US Naval Research Lab.

China's Five-Hundred-Meter Radio Telescope Detects over 900 New Pulsars

China's Five-Hundred-Meter Radio Telescope Detects over 900 New Pulsars

China's Five-hundred-meter Aperture Spherical Radio Telescope (FAST), the world's largest single-dish radio telescope, has identified more than 900 new pulsars since its debut in 2016, its operator said Wednesday, April 17, 2024.

The National Astronomical Observatories under the Chinese Academy of Sciences (NAOC) said that the pulsars included over 120 binary pulsars, more than 170 millisecond pulsars, and 80 faint and intermittent pulsars.

Pulsars, or fast-spinning neutron stars, originate from the imploded cores of massive dying stars through supernova explosions.

Pulsar observation, an important task for FAST, can be used to confirm the existence of gravitational radiation and black holes and study the laws of physics in extreme environments.

According to FAST's operator, less than 3,000 pulsars had been discovered worldwide over the past 50-plus years since the discovery of the first pulsar. The number of new pulsars discovered by FAST is more than three times the total number of pulsars found by telescopes outside China during the same period.

In recent years, FAST has achieved notable success in the study of fast radio bursts, neutral hydrogen, and pulsars, greatly expanding the scope of the human exploration of the universe.

Dubbed the "China Sky Eye," the telescope is located in a naturally deep and round karst depression in the country's southwestern province of Guizhou. It has a reception area equal to 30 standard football fields.

China Satellites Successfully Complete Earth-Moon Communications Tests

China Satellites Successfully Complete Earth-Moon Communications Tests

China's experimental satellites Tiandu-1 and Tiandu-2 that accompanied the Queqiao-2 relay satellite to the Moon in March 2024, have conducted successful new experiments on lunar communication and navigation technologies, China's Deep Space Exploration Lab (DSEL) said on April 13, 2024.

The satellites carried out tests of high-reliability transmission and routing between Earth and the lunar surface. They also transmitted back the latest close-up images of the Moon.

The DSEL says the test satellites will conduct more experiments on lunar communication and navigation technologies, so as to provide strong support for design and construction of the planned International Lunar Research Station and China's own Queqiao integrated satellite network for lunar communication, navigation and remote sensing.

Tiandu-1, weighing 61 kilograms, is equipped with a Ka-band dual-frequency communicator, a laser retroreflector, and a space router.

Tiandu-2, weighing 15 kilograms, is fitted with communication and navigation devices.

China successfully launched the two test satellites along with the Queqiao-2 on March 20.

This orbital configuration provides several advantages over Queqiao, launched in 2018 for Earth-Moon relay communications.

Queqiao-2's orbit is closer to the Moon, greatly improving data transmission rates compared to Queqiao's distant path. It also enhances communication coverage of the lunar south pole region versus Queqiao's position around the Earth-Moon L2 Lagrangian point.

This optimized orbit is more fuel-efficient, allowing Queqiao-2 to maintain operations for an extended period using minimal propellant. Queqiao-2 will provide the relay services planned for ongoing lunar probes Chang'e-4 and the upcoming Chang'e-6 mission, conducting scientific exploration periodically.

The deployment of the Queqiao-2 relay satellite is a key step for China's future lunar exploration missions including Chang'e-6, Chang'e-7 and Chang'e-8.

The landing and sample collection sites for China's moon missions in the coming years are mainly in the lunar south pole region or on the far side of the moon. A more powerful relay satellite with more functions is necessary to provide communications and data transmission services for the missions, China National Space Administration (CNSA) said.

Chang'e-6 is scheduled for launch in the first half of 2024, while Chang'e-7 will be launched around 2026, and Chang'e-8 around 2028. Chang'e-7 and Chang'e-8 will form the basic model of a lunar research station to carry out further exploration of the lunar environment, according to the CNSA.
