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.

How NASA Uses Gravity and Radio Waves to Study Planets and Moons
The Deep Space Network, NASA’s international collection of giant radio antennas used to communicate with spacecraft at the Moon and beyond, helps scientists and engineers use gravity and radio science experiments to learn more about our planetary neighborhood.
After reaching a spacecraft reaches its destination, it uses radio antennas to communicate with the Deep Space Network, which in turn transmits radio signals back to the spacecraft. Every spacecraft travels in a predetermined path emitting radio signals as it orbits around its target. Scientists and engineers can infer the spacecraft's location and how fast it's going by measuring changes in the spacecraft's radio signal frequency. This is made possible by the Doppler effect, the same phenomenon that causes a siren to sound different as it travels towards and away from you.
The Doppler phenomenon is observed here when the spacecraft and the Deep Space Network antenna move in relation to each other. Differences between the frequency of radio signals sent by the spacecraft as it orbits and signals received on Earth give us details about the gravitational field of a planetary body. For example, if the gravity is slightly stronger, the spacecraft will accelerate slightly more. If gravity is slightly weaker, the spacecraft will accelerate slightly less. By developing a model of the planetary body's gravitational field, which can be mapped as a gravitational shape, scientists and researchers can deduce information about its internal structure.
The Deep Space Network was developed by and is managed by NASA’s Jet Propulsion Laboratory (JPL) in Southern California. The antennas of the Deep Space Network are the indispensable link to robotic explorers venturing beyond Earth. They provide the crucial connection for commanding our spacecraft and receiving never-before-seen images and scientific information on Earth, propelling our understanding of the universe, our solar system and ultimately, our place within it.
JPL manages the Deep Space Network for the Space Communications and Navigation (SCaN) Program, based at NASA Headquarters within the Space Operations Mission Directorate.
NASA’s Psyche Asteroid Mission Spacecraft: Huge Solar Arrays Permanently Installed
The solar arrays for NASA’s Psyche mission underwent a final deployment test and were permanently installed on the spacecraft at Astrotech Space Operations near the agency’s Kennedy Space Center in Florida.
Psyche is preparing for a 2.5 billion-mile (4 billion-kilometer) solar-powered trip to the metal-rich asteroid of the same name. In a clean room at Astrotech, the solar arrays were attached to the spacecraft body, unfolded lengthwise, and then re-stowed. This timelapse video was shot over about eight days in late July 2023. The solar arrays provide power for the journey to the asteroid and for operating the spacecraft’s science instruments. When unfolded, each array is 37 feet (11.3 meters) long.
Psyche expects to launch from Kennedy no earlier than Oct. 5, 2023.
