Pumpkin space latte, anyone? ☕

Hubble captured this festive array of stars, Terzan 12, found in the Milky Way about 15,000 light-years from Earth. The stars in this cluster are bound together by gravity in a sphere-like shape and are shrouded in gas and dust. As the starlight travels through that gas and dust to Earth, blue light scatters, leaving the redder wavelengths to come through.

Guy Bluford Changed the Course of Space History

On Aug. 30, 1983, Guion Bluford, better known as Guy, became the first African American to fly to space. An accomplished jet pilot and aerospace engineer, Bluford became part of NASA’s 1978 astronaut class that included the first African American, the first Asian American, and the first women astronauts.

CAPSTONE: Testing a Path to the Moon

Before NASA's Artemis astronauts head to the Moon, a microwave oven-sized spacecraft will help lead the way. The Cislunar Autonomous Positioning System Technology Operations and Navigation Experiment, or CAPSTONE, is a CubeSat mission set to launch in spring of 2022. For at least six months, the small spacecraft will fly a unique elongated path around the Moon. Its trajectory—known as a near rectilinear halo orbit—has never been flown before! Once tried and tested, the same orbit will be home to NASA’s future lunar space station Gateway. Here are five things to know:

1. The 55-pound (25 kg) spacecraft is equipped with solar arrays, cameras, and antennae for communication and navigation.

2. Powerful thrusters will help propel the CubeSat toward the Moon.

3. CAPSTONE will fly a unique elongated path around the Moon for at least six months.

4. At its closest approach, it will come within 2,100 miles (3,380 km) of the Moon's North Pole.

5. The same orbit will be home to Gateway— our future outpost for Artemis astronauts heading to the Moon and beyond.

CAPSTONE is commercially owned and operated by Advanced Space in Westminster, Colorado. NASA’s Small Spacecraft Technology program within the agency’s Space Technology Mission Directorate funds the demonstration mission. The program is based at NASA’s Ames Research Center in California’s Silicon Valley. The development of CAPSTONE’s navigation technology is supported by NASA’s Small Business Innovation Research and Small Business Technology Transfer program. The Artemis Campaign Development Division within NASA’s Exploration Systems Development Mission Directorate funds the launch and supports mission operations. The Launch Services Program at NASA’s Kennedy Space Center in Florida manages the launch.

Other “ solar systems ”. The Milky Way has an average of 200 to 400 billion stars, not all stars have a planet around them, but others could have could have at least one planet around them or even more, could have two, four, eight , or more…  now imagine the diversity of these worlds, all this is only in the Milky Way… Do you believe there is life out there?

Images captured by NASA’s Spitzer Space Telescope. (Some images include data from other telescopes)

The Spitzer Space Telescope is the final mission in NASA’s Great Observatories Program - a family of four space-based observatories, each observing the Universe in a different kind of light. The other missions in the program include the visible-light Hubble Space Telescope (HST), Compton Gamma-Ray Observatory (CGRO), and the Chandra X-Ray Observatory (CXO).

The Cryogenic Telescope Assembly, which contains the a 85 centimeter telescope and Spitzer’s three scientific instruments

The Spacecraft, which controls the telescope, provides power to the instruments, handles the scientific data and communicates with Earth

It may seem like a contradiction, but NASA’s Spitzer Space Telescope must be simultaneously warm and cold to function properly. Everything in the Cryogenic Telescope Assembly must be cooled to only a few degrees above absolute zero (-459 degrees Fahrenheit, or -273 degrees Celsius). This is achieved with an onboard tank of liquid helium, or cryogen.  Meanwhile, electronic equipment in The Spacecraft portion needs to operate near room temperature.

Spitzer’s highly sensitive instruments allow scientists to peer into cosmic regions that are hidden from optical telescopes, including dusty stellar nurseries, the centers of galaxies, and newly forming planetary systems. Spitzer’s infrared eyes also allows astronomers see cooler objects in space, like failed stars (brown dwarfs), extrasolar planets, giant molecular clouds, and organic molecules that may hold the secret to life on other planets.

Spitzer was originally built to last for a minimum of 2.5 years, but it lasted in the cold phase for over 5.5 years. On May 15, 2009 the coolant was finally depleted and the Spitzer “warm mission” began.  Operating with 2 channels from one of its instruments called IRAC, Spitzer can continue to operate until late in this decade.

A cluster of newborn stars herald their birth in this interstellar picture obtained with our Spitzer Space Telescope. These bright young stars are found in a rosebud-shaped (and rose-colored) nebulosity. The star cluster and its associated nebula are located at a distance of 3300 light-years in the constellation Cepheus.

A recent census of the cluster reveals the presence of 130 young stars. The stars formed from a massive cloud of gas and dust that contains enough raw materials to create a thousand Sun-like stars. In a process that astronomers still poorly understand, fragments of this molecular cloud became so cold and dense that they collapsed into stars. Most stars in our Milky Way galaxy are thought to form in such clusters.

The Spitzer Space Telescope image was obtained with an infrared array camera that is sensitive to invisible infrared light at wavelengths that are about ten times longer than visible light. In this four-color composite, emission at 3.6 microns is depicted in blue, 4.5 microns in green, 5.8 microns in orange, and 8.0 microns in red. The image covers a region that is about one quarter the size of the full moon.

As in any nursery, mayhem reigns. Within the astronomically brief period of a million years, the stars have managed to blow a large, irregular bubble in the molecular cloud that once enveloped them like a cocoon. The rosy pink hue is produced by glowing dust grains on the surface of the bubble being heated by the intense light from the embedded young stars. Upon absorbing ultraviolet and visible-light photons produced by the stars, the surrounding dust grains are heated and re-emit the energy at the longer infrared wavelengths observed by Spitzer. The reddish colors trace the distribution of molecular material thought to be rich in hydrocarbons.

The cold molecular cloud outside the bubble is mostly invisible in these images. However, three very young stars near the center of the image are sending jets of supersonic gas into the cloud. The impact of these jets heats molecules of carbon monoxide in the cloud, producing the intricate green nebulosity that forms the stem of the rosebud.

Not all stars are formed in clusters. Away from the main nebula and its young cluster are two smaller nebulae, to the left and bottom of the central ‘rosebud,'each containing a stellar nursery with only a few young stars.

Astronomers believe that our own Sun may have formed billions of years ago in a cluster similar to this one. Once the radiation from new cluster stars destroys the surrounding placental material, the stars begin to slowly drift apart.
