Star Cluster NGC 2244: Inside The Rosette Nebula—Detailed view | NASA Chandra
This composite image shows a close-up detailed view of the Rosette star formation region, located about 5,000 light years from Earth. Data from the Chandra X-ray Observatory are colored red. The x-rays reveal hundreds of young stars in the central star cluster, called NGC 2244, and fainter clusters on either side.

"In the heart of the Rosette Nebula lies a bright open cluster of stars that lights up the nebula. The stars of NGC 2244 formed from the surrounding gas only a few million years ago. This image was taken using multiple exposures and very specific colors of sulfur (shaded red), hydrogen (green), and oxygen (blue). It captures the central region in tremendous detail. A hot wind of particles streams away from the cluster stars and contributes to an already complex menagerie of gas and dust filaments while slowly evacuating the cluster center. The Rosette Nebula's center measures about 50 light-years across, lies about 5,200 light-years away, and is visible with binoculars towards the constellation of the Unicorn (Monoceros)."
The Rosette Nebula in 60 Seconds | NASA Chandra X-ray Observatory
The Rosette Nebula is a star-forming region about 5,000 light years from Earth. X-rays from NASA's Chandra X-ray Observatory reveal about 160 stars in the cluster known as NGC 2237 (right side of the image). Combining X-ray and optical data, astronomers determined that the central cluster formed first, followed by neighboring ones including NGC 2237.

The Rosette Nebula is a star-forming region about 5,000 light years from Earth. Optical data from the Digitized Sky Survey and the Kitt Peak National Observatory show large areas of gas and dust, including giant pillars that remain behind after intense radiation from massive stars has eroded the more diffuse gas.

The Rosette Nebula: Emission-line image | WIYN Telescope
This is a stunning emission-line image of the Rosette Nebula (NGC 2237). It is found in the constellation Monoceros (the Unicorn). The image was taken at the National Science Foundation's 0.9-m telescope on Kitt Peak with the Mosaic camera, and is presented here in false color (hydrogen alpha, OIII oxygen, and SII sulfur respectively red, green and blue, using five ten-minute exposures each). The Rosette is a prominent star formation region, glowing due to ultraviolet light from the young, hot, blue stars whose winds also cleared the central hole. It is enormously large on the sky, covering more than six times the area of the full moon.
Distance: ~5,000 light years

"Would the Rosette Nebula by any other name look as sweet? The bland New General Catalog designation of NGC 2237 does not appear to diminish the appearance of this flowery emission nebula. Inside the nebula lies an open cluster of bright young stars designated NGC 2244. These stars formed about four million years ago from the nebular material and their stellar winds are clearing a hole in the nebula's center, insulated by a layer of dust and hot gas. Ultraviolet light from the hot cluster stars causes the surrounding nebula to glow. The Rosette Nebula spans about 100 light-years across, lies about 5,000 light-years away, and can be seen with a small telescope towards the constellation of the Unicorn (Monoceros)."
The Rosette Nebula (also known as NGC 2237 & Caldwell 49) is an H II region located near one end of a giant molecular cloud in the Monoceros region of the Milky Way Galaxy. The open star cluster NGC 2244 (Caldwell 50) is closely associated with the nebulosity, the stars of the cluster having been formed from the nebula's matter.
Distance: ~5,000 light years
An H II region or HII region is a region of interstellar atomic hydrogen that is ionized. It is typically in a molecular cloud of partially ionized gas in which star formation has recently taken place.
Leonardo Orazi: "The Rosette Nebula (aka NGC 2237) is not the only cosmic cloud of gas and dust to evoke the imagery of flowers . . . This view seemed most appropriate, with a long stem of glowing hydrogen gas in the region included in the composition. At the edge of a large molecular cloud in Monoceros, some 5,000 light years away, the petals of this rose are actually a stellar nursery whose lovely, symmetric shape is sculpted by the winds and radiation from its central cluster of hot young stars. The stars in the energetic cluster, cataloged as NGC 2244, are only a few million years old, while the central cavity in the Rosette Nebula is about 50 light-years in diameter."

Commercial Resupply Mission to the International Space Station | This Week @NASA
Week of August 4, 2023: A commercial resupply mission heads to the International Space Station, a key piece of hardware for a future Moon mission is on the move, and another spacecraft gets ready to spread its wings in deep space . . . a few of the stories to tell you about—This Week at NASA!
Northrop Grumman’s Cygnus spacecraft installation at the International Space Station is now complete. Cygnus, carrying over 8,200 pounds of cargo and science experiments, launched atop the company’s Antares rocket at 8:31 p.m. EDT Tuesday, Aug. 1, 2023, from NASA’s Wallops Flight Facility in Virginia. At 5:52 a.m., NASA astronaut Woody Hoburg, along with NASA astronaut Frank Rubio as backup, captured Cygnus using the station’s Canadarm2 robotic arm.
An international partnership of space agencies provides and operates the elements of the International Space Station (ISS). The principals are the space agencies of the United States, Russia, Europe, Japan, and Canada. The ISS has been the most politically complex space exploration program ever undertaken.
Esto es lo que necesitas saber sobre mundos oceánicos | NASA en Español
Nuestro planeta es un mundo grande y hermoso que está lleno de agua. Y eso es bueno porque toda la vida tal como la conocemos necesita H20 para existir. Pero, ¿sabías que existen vastos océanos de agua líquida en otros mundos de nuestro sistema solar? Esto es lo que necesitas saber sobre los mundos oceánicos.

Panning across Planetary Nebula CVMP 1 in Circinus | NOIRLab
A twenty-second video pan out from the core of the planetary nebula CVMP 1. The international Gemini Observatory composite color image of the planetary nebula CVMP 1 was captured by the Gemini Multi-Object Spectrograph on the Gemini South Telescope on Cerro Pachón in Chile. CVMP 1 formed as the result of a massive star throwing off its outer layers at the end of its life.

NASA's Jet Propulsion Laboratory, a division of Caltech in Pasadena, California, manages the Mars Reconnaissance Orbiter Project for NASA's Science Mission Directorate, Washington.
“For 17 years, MRO has been revealing Mars to us as no one had seen it before,” said the mission’s project scientist, Rich Zurek of JPL.
NASA's Space to Ground: Deep Dive | Week of Aug. 4, 2023
NASA's Space to Ground is your weekly update on what's happening aboard the International Space Station. Northrop Grumman’s Cygnus spacecraft installation at the International Space Station is now complete. Cygnus, carrying over 8,200 pounds of cargo and science experiments, launched atop the company’s Antares rocket at 8:31 p.m. EDT Tuesday, Aug. 1, 2023, from NASA’s Wallops Flight Facility in Virginia. At 5:52 a.m., NASA astronaut Woody Hoburg, along with NASA astronaut Frank Rubio as backup, captured Cygnus using the station’s Canadarm2 robotic arm.
Highlights of space station research facilitated by delivery aboard this Cygnus are:
- The final iteration of a series of spacecraft fire protection experiments
- A new potable water dispenserthat provides hot water and improved sanitization
- Neural cellsthat will be cultured into 3D cell models for gene therapy testing
- A probethat measures plasma density of the upper atmosphere
- A memory cardthat contains creative works from students around the world
Cygnus will remain at the space station until October before it departs for a destructive re-entry into Earth’s atmosphere.

China's Plan for a Crewed Moon Landing in 2029 | Dongfang Hour
China has revealed plans to land two Chinese astronauts on the lunar surface by 2030, and is currently developing a heavy lift rocket, a crewed spacecraft, and a lunar lander to support this mission.
In this episode, we do a deep dive into the space hardware, the timelines, as well as a comparison with Apollo and Artemis.
The coming decade is going to be packed with lunar activity, both crewed and uncrewed!
