This image of the Apple Core Nebula (M27, NGC 6853), a planetary nebula in the constellation of Vulpecula, was taken at the 3.5-meter WIYN telescope in 2020 using the mini-mosaic imager. The Apple Core Nebula is about 850 light-years away from Earth and about 1.5 light-years in diameter (although both distance and size are very poorly constrained). This nebula was formed when an evolved, red giant star ejected its outer envelope near the end of its lifetime. The expanding cloud of gas becomes visible once the hot core of the star, visible near the center, is exposed and the high-energy, ultraviolet light from the core causes the cloud to fluoresce. As a result, the cloud emits light at discrete wavelengths resulting in an emission-line spectrum.
The strongest of the spectral lines are at visible wavelengths are those of singly and doubly ionized oxygen (372.7 nm, OII, and 500.7 nm, OIII, respectively) and hydrogen (656.3 nm, H alpha). This color image was obtained by combining three separate pictures, each one taken through a narrow filter centered at these wavelengths, choosing red to be H alpha (30 minute exposure), green to be OIII (30 minutes) and blue to be OII (60 minutes). The combination produces an unusual, semi-realistic image of the Apple Core Nebula. The green regions indicate locations within the gas cloud where the highest energy radiation is absorbed and doubly ionized oxygen is present. In contrast, regions that are predominantly blue and red indicate where lower energy radiation is being absorbed and the line from doubly ionized oxygen is weaker compared with those of singly ionized oxygen (blue) and hydrogen (red). Since the hot central star emits the same spectrum in all directions, these differences are thought to originate from variations in the density of the expanding cloud.

Spacewalk Scenes of Earth | China Space Station
What can you see after leaving the station's cabin for a spacewalk? The Shenzhou-19 crew aboard the the China Space Station witnessed unique views of our Sun, the Moon, and the stars, plus looks at Earth's magnificent mountains, oceans, rivers, and more . . .
Shenzhou-19 crew members successfully completed a marathon nine-hour spacewalk on December 17, 2024, setting a new long duration record for Chinese astronauts' extravehicular activities (EVAs).
The previous record for the longest spacewalk in Earth orbit was set by the Russian space agency Roscosmos after its cosmonauts completed a spacewalk lasting 8 hours and 13 minutes in 2018. It was set by Expedition 54 Commander Alexander Misurkin and Flight Engineer Anton Shkaplerov of the International Space Station.
At the end of the mission, before closing the hatch, the Shenzhou-19 crew expressed their joy at completing the mission and their gratitude to the ground team.
"Congratulations to 02 for completing your first spacewalk and moreover, for becoming the first Chinese astronaut born after 1990 to carry out EVAs. My appreciation also goes to the full collaboration of 03 inside the module, and to the extensive support of Shuguang and the entire technical team. From the assigned tasks to the more flexible assignments, we feel greater and greater confidence in conducting extravehicular activities. China's space station will always remain something to look forward to," said Cai, commander of Shenzhou-19 spaceflight mission crew.
"I express my gratitude to 01, Shuguang, and all the ground staff. Today, our crew and the ground team worked together to make the extravehicular activities a success. As I admired the spectacular view in space, I felt deep in my heart how important and great a cause the manned spaceflight is. I want to take this opportunity to thank all those who dedicate themselves to this cause—those who were here before us and who are with us along the way. Thank you all for your hard work, so that we were given the chance to conduct a spacewalk. The cause of the manned spaceflight is a relay race, and we are in it every step of the way. Let us keep striving and head for the future together," said Song.
"Congratulations to 01 and 02 for successfully completing your talks. Both of you made breakthroughs and I'm proud of your excellent performance. Meanwhile, my thanks also go to Shuguang and all the staff who worked day and night on this mission. Everybody up in space and on Earth work as one in our exploration and joint efforts for a promising tomorrow. I wish everyone sweet dreams tonight," Wang said.
China launched the Shenzhou-19 crewed spaceship on Oct. 30, 2024, sending three astronauts—including the country's first female space engineer—to its orbiting space station for a six-month mission.

Through NASA’s Artemis campaign, astronauts will land on the lunar surface and use a new generation of spacesuits and rovers as they live, work, and conduct science in the Moon’s South Pole region, exploring more of the lunar surface than ever before. Recently, the agency completed the first round of testing on three commercially owned and developed lunar terrain vehicles (LTVs) from Intuitive Machines, Lunar Outpost, and Venturi Astrolab at NASA’s Johnson Space Center in Houston.
As part of an ongoing year-long feasibility study, each company delivered a static mockup of their vehicle to Johnson at the end of September, initiated rover testing in October and completed the first round of testing in December inside the Active Response Gravity Offload System (ARGOS) test facility. Lunar surface gravity is one-sixth of what we experience here on Earth, so to mimic this, ARGOS offers an analog environment that can offload pressurized suited subjects for reduced gravity simulations.
NASA’s engineering teams conducted tests where suited NASA astronauts and engineers performed tasks, maneuvers, and emergency drills on each rover. With astronauts acting as the test subjects, these human-in-the-loop tests are invaluable as crewmembers provide critical feedback on each rover’s design functionality, evaluate display interfaces and controls, and help identify potential safety concerns or design issues. This feedback is shared directly with each commercial provider, to incorporate changes based on lessons learned as they evolve their rover design.
“We are excited to have mockups from all three LTV commercial providers here at Johnson Space Center,” said Steve Munday, LTV project manager. “This is the first major test milestone within the Lunar Terrain Vehicle Services contract and to have actual rovers delivered only four months after these companies were awarded is remarkable."
Testing consisted of NASA astronauts and engineers taking turns wearing both NASA’s Exploration Extravehicular Mobility Unit planetary prototype spacesuit as well as Axiom Space’s Axiom Extravehicular Mobility Unit lunar spacesuit. The test teams performed evaluations to understand the interactions between the crew, the spacesuits, and the LTV mockups.
While wearing NASA’s prototype spacesuit, crew members were suspended from ARGOS allowing teams to mimic theone-sixth gravitational field of the lunar surface. This allowed the crew members to conduct tasks on the outside of each rover, such as gathering or storing lunar geology tools, deploying science payloads, and handling cargo equipment, as if they are walking on the Moon.
While wearing Axiom Space’s pressurized spacesuit, teams evaluated the level of ease or difficulty in mobility crewmembers experienced when entering and exiting the rovers, the crew compartment and design, and the functionality of interacting with display interfaces and hand controls while wearing thick spacesuit gloves.
As part of testing, teams also conducted emergency drills, where engineers simulated rescuing an incapacitated crew member. As part of NASA’s requirements, each rover must have a design in place that enables an astronaut to single-handedly rescue their crewmates in the event of an emergency.
Since NASA selected the companies, Intuitive Machines, Lunar Outpost, and Venturi Astrolab have been working to meet NASA’s requirements through the preliminary design review. In 2025, the agency plans to issue a request for task order proposals to any eligible providers for a demonstration mission to continue developing the LTV, deliver it to the surface of the Moon, and validate its performance and safety ahead of Artemis V, when NASA intends to begin using the LTV for crewed operations.
Through Artemis, NASA will send astronauts—including the next Americans, and the first international partner astronaut—to explore the Moon for scientific discovery, technology evolution, economic benefits, and to build the foundation for future crewed missions to Mars.

Roscosmos cosmonauts Alexey Ovchinin and Ivan Vagner of Russia concluded their spacewalk (RU EVA-63) on December 19, 2024, at 5:53 p.m. EST after seven hours and 17 minutes. Ovchinin and Vagner completed all of their major objectives. This included installing an experiment package designed to monitor celestial x-ray sources and new electrical connector patch panels and removing several experiments for disposal. The two cosmonauts were unable to complete their non-critical final extravehicular (EVA) objective due to time constraints. This was to relocate a control panel for the European robotic arm, attached to the Nauka multipurpose laboratory module.
