This image of the reflection nebula Messier 78 was captured using the Wide Field Imager camera on the MPG/ESO 2.2-meter telescope at the La Silla Observatory, Chile. This color picture was created from many monochrome exposures taken through blue, yellow/green and red filters, supplemented by exposures through a filter that isolates light from glowing hydrogen gas. The total exposure times were 9, 9, 17.5 and 15.5 minutes per filter, respectively.

The Birth of the Hunter | ESO

The Birth of the Hunter | ESO

The constellation of Orion (The Hunter) is one of the most recognisable collections of stars in the night sky. We have noted Orion’s prominent stars for tens of thousands of years at least, and likely far longer. Chinese astronomers called it 参宿 or Shēn, literally “three stars”, for its three bright dots (which form the Hunter’s belt). The ancient Egyptians regarded it as the gods Sah and Sopdet, manifestations of Osiris and Isis, respectively, whereas Greek astronomers saw a brave hunter—the eponymous Orion—with his sword above his head, ready to strike.

Mythology aside, Orion is a fascinating patch of sky. This image, from the European Southern Observatory's Very Large Telescope, shows a reflection nebula nestled at the heart of the constellation—NGC 2023. Located close to the well-known Horsehead and Flame Nebulae, NGC 2023 lurks about 1,500 light-years away from Earth, and is one of the largest reflection nebulae in the sky.

Reflection nebulae are clouds of interstellar dust that reflect the light from nearby or internal sources, like fog around a car headlight. NGC 2023 is illuminated by a massive young star named HD 37903. The star is extremely hot—several times hotter than the Sun—and its bright blue-white light causes NGC 2023’s milky glow. Such nebulae are often the birthplaces of stars, and contain a clumpy distribution of gas that’s significantly denser than the surrounding medium. Under the influence of gravity, these clumps attract one another and merge, eventually creating a new star. In a few million years time, Orion's Belt may gain a new star!

The image was taken with the Very Large Telescope’s FORS (FOcal Reducer and Spectrograph) instrument as part of the ESO Cosmic Gems program. This initiative produces images of interesting and visually attractive objects using ESO telescopes, for the purposes of education and outreach. The program makes use of telescope time that cannot be used for science observations. All data collected may also be suitable for scientific purposes, and are made available to astronomers through ESO’s science archive.

Zoom into Double Star within Orion's Trapezium Cluster | ESO

Zoom into Double Star within Orion's Trapezium Cluster | ESO

As part of the first observations with the GRAVITY instrument, the European Southern Observatory team looked closely at the bright, young stars known as the Trapezium Cluster, located in the heart of the Orion star-forming region. Already, from these first data, GRAVITY made a discovery: one of the components of the cluster (Theta1 Orionis F) was found to be a double star for the first time.

This zoom video starts with a broad view of the famous constellation of Orion (The Hunter) and then shows successively more detailed images of the region with different telescopes. The final view from GRAVITY reveals far finer detail around one of the fainter cluster stars than could be detected even with the NASA/European Space Agency Hubble Space Telescope.

The Trapezium Cluster | ESO

The Orion Nebula is arguably the finest of all nebulae within the Milky Way visible from the Northern Hemisphere. With a gaseous repository of 10,000 suns, and illuminated by a cluster of hot young stars, the clouds of Messier 42—as it is also known—glow with fantastic colors and shapes, giving us a bird’s eye view of one of the greatest star forming nurseries in our part of the Milky Way. Messier 42 is a complex of glowing gas, mostly hydrogen but also helium, carbon, nitrogen, and oxygen in decreasing amounts, located 1,500 light-years away. At its very heart, we find the Trapezium, a group of four very hot stars that illuminate the nebula. They are the brightest of an extended cluster of several thousand young stars many of which lie unseen within the opaque gas and dust. Amazingly, while the Orion Nebula is easy to identify with the unaided eye, there is apparently no written record of its existence before the 17th century. The Trapezium Cluster was discovered by Galileo Galilei.

NASA Artemis I Path to the Pad: The Spacecraft

Named after one of the largest constellations in the night sky, Orion is the name given to the spacecraft that will carry the first woman and first person of color to the Moon. However, before we fly astronauts aboard, the spacecraft, powered by our Space Launch System (SLS) rocket, will travel tens of thousands of miles on a flight test around the Moon. Watch as teams at NASA's Kennedy Space Center prepare Orion for that journey, outfitting the spacecraft with its necessary components as it moves along its path to the pad.

NASA Artemis III Moon Mission: Candidate Regions for Landing Humans

NASA Artemis III Moon Mission: Candidate Regions for Landing Humans

Shown here is a rendering of 13 candidate landing regions for Artemis III. Each region is approximately 9.3 by 9.3 miles (15 by 15 kilometers). A landing site is a location within those regions with an approximate 328-foot (100-meter) radius.

As NASA prepares to send astronauts back to the Moon under Artemis, the agency has identified 13 candidate landing regions near the lunar South Pole. Each region contains multiple potential landing sites for Artemis III, which will be the first of the Artemis missions to bring crew to the lunar surface, including the first woman to set foot on the Moon.

NASA identified the following candidate regions for an Artemis III lunar landing:

Faustini Rim A

Peak Near Shackleton

Connecting Ridge

Connecting Ridge Extension

de Gerlache Rim 1

de Gerlache Rim 2

de Gerlache-Kocher Massif

Haworth

Malapert Massif

Leibnitz Beta Plateau

Nobile Rim 1

Nobile Rim 2

Amundsen Rim

Each of these regions is located within six degrees of latitude of the lunar South Pole and, collectively, contain diverse geologic features. Together, the regions provide landing options for all potential Artemis III launch opportunities. Specific landing sites are tightly coupled to the timing of the launch window, so multiple regions ensure flexibility to launch throughout the year.

To select the regions, an agencywide team of scientists and engineers assessed the area near the lunar South Pole using data from NASA’s Lunar Reconnaissance Orbiter and decades of publications and lunar science findings. In addition to considering launch window availability, the team evaluated regions based on their ability to accommodate a safe landing, using criteria including terrain slope, ease of communications with Earth, and lighting conditions. To determine accessibility, the team also considered combined capabilities of the Space Launch System rocket, the Orion spacecraft, and the SpaceX-provided Starship human landing system.

All regions considered are scientifically significant because of their proximity to the lunar South Pole, which is an area that contains permanently shadowed regions rich in resources and in terrain unexplored by humans.

The analysis team weighed other landing criteria with specific Artemis III science objectives, including the goal to land close enough to a permanently shadowed region to allow crew to conduct a moonwalk, while limiting disturbance when landing. This will allow crew to collect samples and conduct scientific analysis in an uncompromised area, yielding important information about the depth, distribution, and composition of water ice that was confirmed at the Moon’s South Pole.

The team identified regions that can fulfill the moonwalk objective by ensuring proximity to permanently shadowed regions, and also factored in other lighting conditions. All 13 regions contain sites that provide continuous access to sunlight throughout a 6.5-day period – the planned duration of the Artemis III surface mission. Access to sunlight is critical for a long-term stay at the Moon because it provides a power source and minimizes temperature variations.

NASA will discuss the 13 regions with broader science and engineering communities through conferences and workshops to solicit input about the merits of each region. This feedback will inform site selections in the future, and NASA may identify additional regions for consideration. The agency will also continue to work with SpaceX to confirm Starship’s landing capabilities and assess the options accordingly.

NASA will select sites within regions for Artemis III after it identifies the mission’s target launch dates, which dictate transfer trajectories and surface environment conditions.

Through Artemis, NASA will land the first woman and the first person of color on the Moon, paving the way for a long-term, sustainable lunar presence and serving as a steppingstone for future astronaut missions to Mars.
