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.

Remote Island Tristan da Cunha | International Space Station & Landsat 9 Images

Remote Island Tristan da Cunha | International Space Station & Landsat 9 Images

Expedition 56 image of Tristan da Cunha island from the International Space Station

Landsat 9 Image of Tristan da Cunha island (labeled)

Landsat 9 Image | From left to right: Inaccessible Island, Nightingale Island, & Tristan da Cunha (upper right-hand corner)

Life finds ways to survive on this small volcanic island chain that is way off the beaten path . . .

Tristan da Cunha, often said to be the most remote inhabited island in the world, is the sort of place where seabirds outnumber people. It is part of an island group in the South Atlantic Ocean situated approximately halfway between the southern tips of South America and Africa. Neighboring volcanic peaks within the group include the smaller, uninhabited Inaccessible Island and the Nightingale Islands.

The OLI-2 (Operational Land Imager-2) on Landsat 9 captured its image of the island group on May 24, 2023. Tristan da Cunha’s highest point, Queen Mary’s Peak, reaches 2,060 meters (6,760 feet) above sea level and displays steep gullies that radiate downward on all sides.

The island’s vegetation is divided into distinct zones related to elevation. Large tussock-forming grasses once covered the island’s coastal fringes, but most of this has become pasture, according to the Royal Botanic Gardens, Kew. Woodlands of Phylica arborea, known as island cape myrtle, cover the volcano’s lower slopes (dark green) and transition into ecosystems that include tree ferns, sphagnum moss, small grasses, bryophytes, and lichens on its upper reaches (light green).

Offshore, underwater forests of giant kelp surround the islands. The kelp, Macrocystis pyrifera, is one of the fastest-growing seaweeds on the planet. Though suspended sediment may be discoloring the water in some areas, signs of kelp forests (green) are visible in several areas immediately offshore. In preparation for an ecological survey of the island’s marine ecosystems, a team of National Geographic researchers used dozens of Landsat 7 and 8 images to locate the likely locations of kelp forests and plan underwater surveys.

About 240 people live in Edinburgh of the Seven Seas, the small town on the northern edge of the island. The main occupations are fishing and farming. Many residents harvest crayfish—sold as Tristan rock lobster—and raise potatoes and livestock. Away from town, thousands of birds, including populations of northern rockhopper penguins, Atlantic yellow-nosed albatross, and broad-billed prion, nest on the small, circular island.

The number of birds might be higher if mice and rats had not found their way to the islands. Likely introduced by sailors in the 1800s, rodent populations have boomed, despite an annual rat hunting competition and holiday. The small mammals are thought to eat large numbers of bird eggs and young birds.

Ecologists have warned that an abundance of oversized mice may even be on the verge of pushing a critically endangered seabird, the Tristan albatross, to the brink of extinction on Gough Island (out of the scene to the southeast). Another notable species on Inaccessible Island is the Inaccessible Island rail, the smallest living flightless bird in the world.

All of the islands are the product of a volcanic hot spot, a type of volcanism that brings magma from deep within Earth’s mantle. Tristan da Cunha, the youngest and largest of the group, formed about 200,000 years ago. It last erupted in October 1961, forcing people on the island to evacuate. Radiometric dating techniques indicate that Nightingale is the oldest of the three main islands, with volcanic rocks ranging from 360,000 to 18 million years old. Inaccessible Island has rocks that range from 1 million to 6 million years old.

The Mysteries of Irregular Galaxy UGC 8201 in Draco | Hubble

The Mysteries of Irregular Galaxy UGC 8201 in Draco | Hubble

The galaxy UGC 8201, captured here by the NASA/European Space Agency Hubble Space Telescope, is a dwarf irregular galaxy, so called because of its small size and chaotic structure. It lies just under 15 million light-years away from us in the constellation of Draco (the Dragon). As with most dwarf galaxies it is a member of a larger group of galaxies. In this case UCG 8201 is part of the M81 galaxy group; this group is one of the closest neighbors to the Local Group of galaxies, that contains our galaxy, the Milky Way.

UGC 8201 is at an important phase in its evolution. It recently completed a long period of star formation. This had significant impact on the entire galaxy. It lasted for several hundred million years and produced a high number of newborn bright stars. These stars can be seen in this image as the dominating light source within the galaxy. This process also changed the distribution and amount of dust and gas in between the stars in the galaxy.

Such large star formation events need extensive sources of energy to trigger them. However, compared to larger galaxies, dwarf galaxies lack such sources and they do not appear to have enough gas to produce as many new stars as they do. This raises an important unanswered question in galaxy evolution: How do relatively isolated, low-mass systems, such as dwarf galaxies, sustain star formation for extended periods of time?

Due to its relative proximity to Earth, UGC 8201 is an excellent object for research and provides an opportunity to improve our understanding of how dwarf galaxies evolve and grow.

The coordinates of the Chang'e 6 landing site are latitude 36.1 degrees south latitude, 208.3 degrees east longitude with a horizontal accuracy of plus or minus 30 meters. 

NASA Lunar Reconnaissance Orbiter (LRO) image of China Chang'e-6 Moon Lander. This independently confirmed the successful landing of Chang'e-6 on the Moon's Far Side South Pole-Aitken Basin on June 2, 2024 with support from China's Queqiao-2 Lunar Relay Satellite.

This before and after animation of NASA Lunar Reconnaissance Orbiter (LRO) images shows the appearance of the Chang’e 6 lander. The increased brightness of the terrain surrounding the lander is due to disturbance from the lander’s engines and is similar to the blast zone seen around other lunar landers. The before image is from March 3, 2022, and the after image is from June 7, 2024.

Chang'e-6 Moon Lander with Ascender on top on June 3, 2024: View from min-rover

China Chang'e-6 Moon Mission Lander Poster: Celebrating June 2, 2024 Far Side South Pole Landing

The ascender of China's Chang'e-6 probe successfully lifted off from the Moon's surface on June 4, 2024, carrying samples collected from the Moon's far side south pole—for the first time in human lunar exploration history. The Chang'e-6 probe—consisting of an orbiter, a lander, an ascender and a returner, like its predecessor Chang'e-5—was launched on May 3, 2024. After a month-long journey, Chang'e-6's lander-ascender combination touched down at the designated landing area in the South Pole-Aitken (SPA) Basin on Sunday, June 2, 2024. The lander is on the rim of an eroded, 55-yard-diameter (about 50 meters) crater.

The SPA basin (43°±2° south latitude, 154°±4° west longitude) is a large impact crater on the far side of the Moon. At roughly 2,500 km (1,600 mi) in diameter and between 6.2 and 8.2 km (3.9–5.1 mi) deep, it is the largest, oldest, and deepest basin recognized on the Moon.

The Chang’e 6 landing site is situated toward the southern edge of the Apollo basin (about 306 miles or 492 km in diameter, centered at 36.1 degrees south latitude, 208.3 degrees east longitude). Basaltic lava erupted south of Chaffee S crater about 3.1 billion years ago and flowed downhill to the west until it encountered a local topographic high, likely related to a fault. Several wrinkle ridges in this region have deformed and raised the mare surface. The landing site sits about halfway between two of these prominent ridges. This basaltic flow also overlaps a slightly older flow (about 3.3 billion years old), visible further west, but the younger flow is distinct because it has higher iron oxide and titanium dioxide abundances.

The Chang'e-6 ascender rendezvoused and docked with the orbiter-returner combination and transferred the lunar samples to the returner on June 6, 2024. The combination is flying around the Moon, waiting for the right time to return. Near the Earth, the returner will re-enter the atmosphere carrying the lunar samples. It is scheduled to land at the Siziwang Banner landing site in north China's Inner Mongolia region around June 25, 2024.

In 2020, Chang'e-5 was the first lunar sample-return mission since the Soviet Union's Luna 24 in 1976. The mission made China the third country to return samples from the Moon after the United States and the Soviet Union.

Robots at Work: Canadarm2 & Dextre | International Space Station

Robots at Work: Canadarm2 & Dextre | International Space Station

The Canadarm2 robotic arm with Dextre, its fine-tuned robotic hand attached, extends from the International Space Station while orbiting 263 miles above the Atlantic Ocean.

Dextre, the fine-tuned robotic hand attached to the Canadarm2 robotic arm, extends from the International Space Station while orbiting 259 miles above the Pacific Ocean southwest of Baja California.

The 17-meter-long (55+ feet) Canadarm2 robotic arm, with the 3.7m (12 feet) high Dextre fine-tuned robotic hand attached is pictured here. Canadarm2 and Dextre are part of Canada's contribution to the International Space Station (ISS). Canadarm2 was extensively involved in the assembly of the orbiting laboratory.

Dextre tackles the tough or routine jobs that need to be done in the harsh environment of space. The Station's robotic assistant allows astronauts to spend more time doing scientific experiments instead of performing risky spacewalks. 

Dextre's body was designed to move in many different ways. Each of its arms has seven joints that can move up and down, go from side to side, and rotate. This large range of motion means Dextre can actually carry out more complex movements than a human arm. Each hand has a retractable motorized wrench, a camera and lights for close-up viewing, and a retractable connector to provide power, data and video connection. The robot can carefully grip delicate equipment without causing damage. For example, it can successfully manipulate small safety caps, cables and wires with minute precision—all while being controlled from Earth, hundreds of kilometers away. Dextre can can ride on the end of Canadarm2 to move from each worksite or be ferried on the Mobile Base System to work almost anywhere on the ISS. 

The robot is operated by ground control teams at the Canadian Space Agency (CSA) headquarters outside Montreal, Quebec, and at NASA.

Zooming to Newly Awakened Black Hole in Galaxy SDSS1335+0728 | ESO

Zooming to Newly Awakened Black Hole in Galaxy SDSS1335+0728 | ESO

This video zooms into the galaxy SDSS1335+0728. In late 2019 it suddenly started shining brighter than ever before and was classified as having an active galactic nucleus (AGN). This is the first time the awakening of a massive black hole has been observed in real time.

Images shown here were taken with different telescopes at different times. They have been blended together to create this zoom.

This research was presented in a paper entitled “SDSS1335+0728: The awakening of a ∼ 106M⊙ black hole” published in Astronomy & Astrophysics (https://aanda.org/10.1051/0004-6361/202347957).

New Discovery: Massive Galactic Black Hole Awakening [Artist Animation] | ESO

New Discovery: Massive Galactic Black Hole Awakening [Artist Animation] | ESO

This animation shows the growing disc of material around the massive black hole at the center of the galaxy SDSS1335+0728. In late 2019 this galaxy suddenly started shining brighter than ever before and was classified as having an active galactic nucleus (AGN), powered by the central black hole feeding off the surrounding material.

This artist’s impression shows a ring of dark yellow clouds surrounding a brighter yellow region on a dark background, including an especially bright white dot at its center. Bright yellow, red, white, and blue stars dot the image.

Astronomers have used data from several space and ground-based observatories, including the European Southern Observatory’s Very Large Telescope (ESO’s VLT), to track how the galaxy’s brightness has varied. In a study out today, they conclude that they are witnessing changes never seen before in a galaxy—likely the result of the sudden awakening of the massive black hole at its core.

“Imagine you’ve been observing a distant galaxy for years, and it always seemed calm and inactive,” says Paula Sánchez Sáez, an astronomer at ESO in Germany and lead author of the study accepted for publication in Astronomy & Astrophysics. 

“Suddenly, its [core] starts showing dramatic changes in brightness, unlike any typical events we've seen before.” This is what happened to SDSS1335+0728, which is now classified as having an ‘active galactic nucleus’ (AGN)—a bright compact region powered by a massive black hole—after it brightened dramatically in December 2019.

Like supernova explosions or tidal disruption events—when a star gets too close to a black hole and is torn apart—it can make galaxies suddenly light up. However, these brightness variations typically last only a few dozen or, at most, a few hundreds of days. SDSS1335+0728 is still growing brighter today, more than four years after it was first seen to ‘switch on’. Moreover, the variations detected in the galaxy, located 300 million light-years away in the constellation Virgo, are unlike any seen before, pointing astronomers towards another explanation.

Massive black holes—with masses over one hundred thousand times that of our Sun—exist at the center of most galaxies, including the Milky Way. “These giant monsters usually are sleeping and not directly visible,” explains co-author Claudio Ricci, from the Diego Portales University, also in Chile. “In the case of SDSS1335+0728, we were able to observe the awakening of the massive black hole, [which] suddenly started to feast on gas available in its surroundings, becoming very bright.”

“[This] process (...) has never been observed before,” Hernández García says. Previous studies reported inactive galaxies becoming active after several years, but this is the first time the process itself—the awakening of the black hole—has been observed in real time. Ricci, who is also affiliated with the Kavli Institute for Astronomy and Astrophysics at Peking University, China, adds: “This is something that could happen also to our own Sgr A*, the massive black hole (...) located at the center of our galaxy," but it is unclear how likely this is to happen. 

Follow-up observations are still needed to rule out alternative explanations. Another possibility is that we are seeing an unusually slow tidal disruption event, or even a new phenomenon. If it is in fact a tidal disruption event, this would be the longest and faintest such event ever observed. “Regardless of the nature of the variations, [this galaxy] provides valuable information on how black holes grow and evolve,” Sánchez Sáez says.
