China Launches SVOM Gamma Ray Astronomy Satellite Developed with France

China Launches SVOM Gamma Ray Astronomy Satellite Developed with France

On Saturday, June 22, 2024, China successfully launched an astronomy satellite—the result of nearly 20 years of hard work between Chinese and French scientists. It will capture gamma-ray bursts that flicker like fireworks in the farthest reaches of the universe.

The satellite, the Space-based Multi-band Variable Object Monitor (SVOM), was launched by a Long March-2C rocket from the Xichang Satellite Launch Center in southwest China's Sichuan Province, according to the China National Space Administration (CNSA).

It is the most powerful satellite to carry out multi-band comprehensive observations of gamma-ray bursts to date. It will play an important role in scientific studies of high-energy astronomical phenomena.

The 930kg (2,050-pound) satellite, which took hundreds of scientists and engineers nearly two decades to develop, will orbit Earth at 625km (450 miles) above the ground to accurately measure the location and energy of distant, violent explosions known as gamma-ray bursts.

China is primarily responsible for the mission, launch, satellite and operations, and shared responsibility with France for the design and construction of the instruments and ground segment.

The French contribution was developed in partnership with research laboratories at the IRFU research institute at CEA, the French atomic energy and alternative energies commission, and at INSU, the national institute of universe science, and IN2P3, the national institute of nuclear and particle physics, both attached to the national scientific research centre CNRS.

Red Sprites Spotted off South African Coast | International Space Station

Red Sprites Spotted off South African Coast | International Space Station

Close-up view of red sprites off South African Coast

High-resolution wide-view of red sprites off South African Coast

NASA astronaut Matthew Dominick: "Super lucky a few weeks ago when shooting a timelapse of a lightning storm off the coast of South Africa. One of the frames in the timelapse had a red sprite. A rare event. My knowledge is pretty much just from Wikipedia but I want to know more."

Red Sprites: These mysterious bursts of light in the upper atmosphere momentarily resemble gigantic jellyfish. One unusual feature of sprites is that they are relatively cold. They operate more like long fluorescent light tubes than hot compact light bulbs. In general, red sprites take only a fraction of a second to occur and are best seen when powerful thunderstorms are visible from the side.

Milky Way & Large Magellanic Cloud Galaxies+Aurora over Western Australia

Milky Way & Large Magellanic Cloud Galaxies+Aurora over Western Australia

Astrophotographer Trevor Dobson: "This is an 8 shot panorama of the recent Aurora event of May 11. In this shot you can see the Aurora Australis, aka the Southern Lights, with the Crux/Carina region of the Milky Way above it. The Large Magellanic Cloud is also visible on the far right centre of the image."

For many people, the aurora is a beautiful nighttime phenomenon that is worth traveling to Earth's polar regions just to observe. It is the only way for most people to actually experience space weather. 

Earth auroras have different names depending on the pole where they occur. Aurora Borealis, or the northern lights, is the name given to auroras around the north pole and Aurora Australis, or the southern lights, is the name given for auroras around the south pole.

NASA's Chandra X-ray Observatory Peers into Densest & Strangest Stars

NASA's Chandra X-ray Observatory Peers into Densest & Strangest Stars

Astronomers have taken an important step toward understanding examples of the densest and strangest objects in the Universe by using NASA’s Chandra X-ray Observatory and the European Space Agency’s XMM-Newton. These results show that the interiors of neutron stars may contain a special type of ultra-dense matter that does not exist anywhere else in the universe.

Neutron stars are the dense cores that can form after massive stars collapse. They are so dense that a teaspoon of their matter weighs about a trillion pounds.

The team in this new study analyzed previously released data from neutron stars to determine the so-called equation of state. This refers to the basic properties of the neutron stars including the pressures and temperatures in their interiors.

The authors used machine learning, a type of artificial intelligence, to compare the data to different equations of state. Their results imply that a significant fraction of the equations of state—the ones that do not include the capability for rapid cooling at higher masses—can be ruled out.

The researchers capitalized on neutron stars in the study being located in supernova remnants, including 3C 58. Since astronomers have age estimates of the supernova remnants, they also have the ages of the neutron stars that were created during the explosions that created both the remnants and the neutron stars. The astronomers found that the neutron star in 3C58 and two others were much cooler than the rest of the neutron stars in the study.

The team thinks that part of the explanation for the rapid cooling is that these neutron stars are more massive than most of the rest. Because more massive neutron stars have more particles, special processes that cause neutron stars to cool more rapidly might be triggered.

One possibility for what is inside these neutron stars is a type of radioactive decay near their centers where neutrinos—low mass particles that easily travel through matter—carry away much of the energy and heat, causing rapid cooling. Another possibility is that there are types of exotic matter found in the centers of these more rapidly cooling neutron stars.

These are objects that seem to just get more interesting the more scientists examine them!

Shenzhou-18 Crew Performs Health & Science Experiments | China Space Station

Shenzhou-18 Crew Performs Health & Science Experiments | China Space Station

The Shenzhou-18 crew has carried out a series of in-orbit experiments, physical exercises, and their first extravehicular activities over the past one and a half months since they entered the China's space station on April 26, 2024.

The three Chinese astronauts, Ye Guangfu, Li Cong and Li Guangsu, were sent to the orbiting space station for a six-month mission on April 25, from the Jiuquan Satellite Launch Center in northwest China.

Four zebrafish and hornwort were brought into orbit via the Shenzhou-18 spaceship for a life science and ecological experiment.

So far, the astronauts have successfully carried out two water samplings and one fish food container replacement. They have found abnormal directional behaviors of the zebrafish in microgravity, such as making rotational movements, going in circles and even swimming upside-down.

The water samples, fish eggs, and videos recording spatial movement behaviors of the zebrafish will be sent back to Earth for scientists to study the influence of the space environment on the growth and behaviors of vertebrates. This will provide references for research on material circulation of contained ecosystems in space.

The three astronauts completed the mission to replace samples of the container-free material cabinet. Previously, a number of key research projects had been carried out in the container-free cabinet, and many batches of experimental samples had been brought back to Earth for further tests and investigation.

The Shenzhou-18 crew also replaced a burner, plus vacuumized and exhausted waste gas on the combustion experimental cabinet.

The combustion experimental cabinet is one of the eight experimental cabinets carried by Mengtian, a lab module of China's space station. It can help scientists carry out in-depth research on basic science problems of combustion, space propulsion, fire safety for spacecraft, combustion pollution control, and other basic and applied technologies.

They have completed the installation of the conversion cable of the combustion solenoid valve, that can remotely controlled the switch of the solenoid valve, to accurately control fuel flow during experiments.

The crew also assembled and tested material extravehicular exposure of experimental equipment.

The astronauts in space face a series of physiological challenges brought about by the microgravity environment, including changes in the cardiovascular system, muscle atrophy, and bone density loss.

The three astronauts used an ultrasound diagnostic device to complete carotid artery ultrasound imaging and spectrum testing, and used an instrument to perform bone density testing.

They have performed regular weightlessness protection exercises, such as treadmill training and resistance training, so as to maintain good physical condition for the half-year mission.

The trio cooperated closely to complete the first spacewalk of their mission on May 28, 2024. They spent about 8.5 hours working outside the Tiangong space station and completed multiple tasks, including the installation of space debris protection devices. It was the longest spacewalk or extravehicular activity (EVA) record for China to date.

During the in-orbit stay of the Shenzhou-18 mission crew, they will take care of the space station and application payloads as planned, and carry out maintenance and inspection of the space station, so as to ensure the station's safe, reliable and efficient operation.

The crew will utilize scientific experiment cabinets and extravehicular payloads to conduct more than 90 experiments in the fields of basic physics in microgravity, space material science, space life science, space medicine and space technology.

The Serpens Nebula: Objects Identified | James Webb Space Telescope

The Serpens Nebula: Objects Identified | James Webb Space Telescope

For the first time, a phenomenon astronomers have long hoped to image directly has been captured by the NASA/European Space Agency/Canadian Space Agency James Webb Space Telescope’s Near-InfraRed Camera (NIRCam). In this detailed image of the Serpens Nebula, the discovery lies in the northern area of this young, nearby star-forming region.

The astronomers found an intriguing group of protostellar outflows, formed when jets of gas spewing from newborn stars collide with nearby gas and dust at high speeds. Typically these objects have a variety of orientations within one region. Here, however, they are all slanted in the same direction, to the same degree, like sleet pouring down during a storm.

The discovery of these aligned objects, made possible only by Webb’s exquisite spatial resolution and sensitivity at near-infrared wavelengths, is providing information about the fundamentals of how stars are born.

This video showcases the new Webb Serpens Nebula image, with notable features and objects highlighted.

The Serpens Nebula, located 1,300 light-years from Earth, is home to a particularly dense cluster of newly forming stars (about 100,000 years old), where a number will eventually grow to the mass of our Sun. Webb’s image of this nebula revealed a grouping of aligned protostellar outflows (seen in the top left). The jets are identified by bright clumpy streaks that appear red. These are shock waves caused when the jet hits the surrounding gas and dust.

Serpens Nebula North: Aligned Protostellar Outflows | James Webb Space Telescope

This image from the NASA/European Space Agency/Canadian Space Agency James Webb Space Telescope shows a portion of the Serpens Nebula where astronomers have discovered a grouping of aligned protostellar outflows. The jets are represented by bright clumpy streaks that appear red. These are shock waves from the jet hitting surrounding gas and dust. Here, the red color represents the presence of molecular hydrogen and carbon monoxide.

Typically these objects have a variety of orientations within one region. Here, however, they are all slanted in the same direction, to the same degree, like sleet pouring down during a storm. Researchers say the discovery of these aligned objects, made possible only by Webb’s exquisite spatial resolution and sensitivity at near-infrared wavelengths, is providing information about the fundamentals of how stars are born.

Image Description: A portion of the young star-forming region known as the Serpens Nebula. It is filled with wispy orange and red layers of gas and dust and within that orange dust are several small red plumes of gas that extend from the top left to the bottom right, at the same angle. There are wispy blue filaments of gas in the bottom right corner of the image. Small points of light are sprinkled across the field. The brightest sources in the field have the eight-pointed diffraction spikes that are characteristic of the James Webb Space Telescope.
