At the End of the Rainbow: Star Cluster Superbubble NGC 1929 | NASA Chandra

Looking up at the night sky, you might think that space is dull, with lots of black, some white dots and just a hint of red if you are lucky. However, if we look deeper, space has a lot more to offer than what our eyes can see!

You have probably heard the phrase 'visible light'. This is what we call the range of colors that humans can see with their eyes. Visible light is just a tiny portion of all light. So astronomers have built special telescopes to see things that human eyes can't! For this picture, three telescopes were used and each picked up a different type of light.

This image shows a 'superbubble', a cloud of hot gas blown away from bright, young stars at its center. The superbubble has been captured with one of the telescopes in X-ray light, which has been colored blue. X-rays have a lot of energy, so when we look at the Universe in X-ray light, we see some of the hottest gas and most powerful explosions.

Infrared light is given off by much cooler objects than stars. For example, humans give off infrared light of our own! In this picture, infrared shows us the colder gas and dust of the superbubble, colored in red. This part of the picture was taken with the second telescope. The rest of the picture is yellow, showing us visible light. These are the parts of the image that we could see with our own eyes, if we were close enough, and if our eyes were sensitive enough!

The star cluster known as NGC 1929 is embedded in a cloud of gas and dust, which astronomers call the N44 nebula. Many new stars, some of them very massive, are forming within this star cluster. These massive stars produce intense radiation, expel matter at high speeds, and race through their evolution to explode as supernovas. The winds and supernova shock waves carve out huge cavities called superbubbles in the surrounding gas. 

X-rays from NASA's Chandra X-ray Observatory show hot regions created by these winds and shocks. Meanwhile, infrared data from NASA's Spitzer Space Telescope outline where the dust and cooler gas are found. An optical light image from a European Space Observatory (ESO) telescope in Chile shows where ultraviolet radiation from hot, young stars is causing gas in the nebula to glow.

The Nebula N44 Superbubble: Hubble’s Inside The Image | NASA Goddard

The Hubble Space Telescope has taken over 1.5 million observations over the past 32 years. One of them is the breathtaking Nebula known as the N44 Superbubble.

N44 is a complex nebula filled with glowing hydrogen gas, dark lanes of dust, massive stars, and many populations of stars of different ages. One of its most distinctive features, however, is the dark, starry gap called a “superbubble,” visible in the upper central region. 

In this video, Dr. Ken Carpenter takes us on a journey through the Nebula, teaching us some of the interesting science behind this famous Hubble image.

Mysterious “Superbubble” Hollows Out Nebula N44 in Dorado | Hubble

Mysterious “Superbubble” Hollows Out Nebula N44 in Dorado | Hubble

N44 is a complex nebula filled with glowing hydrogen gas, dark lanes of dust, massive stars, and many populations of stars of different ages. One of its most distinctive features, however, is the dark, starry gap called a “superbubble,” visible in this Hubble Space Telescope image in the upper central region.

Image Description: Upper 2/3 holds a bright white and blue gas and dust-cloud ring around a central void or bubble. Lower 1/3 holds blue and white "cotton ball" like clouds, several holding bright stars. Reddish-orange stars also dot the scene throughout.

The hole is about 250 light-years wide and its presence is still something of a mystery. Stellar winds expelled by massive stars in the bubble's interior may have driven away the gas, but this is inconsistent with measured wind velocities in the bubble. Another possibility, since the nebula is filled with massive stars that would expire in titanic explosions, is that the expanding shells of old supernovae sculpted the cosmic cavern.

Astronomers have found one supernova remnant in the vicinity of the superbubble and identified an approximately 5 million year difference in age between stars within and at the rim of the superbubble, indicating multiple, chain-reaction star-forming events. The deep blue area at about 5 o’clock around the superbubble is one of the hottest regions of the nebula and the area of the most intense star formation.

N44 is an emission nebula, which means its gas has been energized, or ionized, by the radiation of nearby stars. As the ionized gas begins to cool from its higher-energy state to a lower-energy state, it emits energy in the form of light, causing the nebula to glow. Located in the Large Magellanic Cloud, N44 spans about 1,000 light-years and is about 170,000 light-years away from Earth.

Panning on Interacting Galaxies Arp 87 | Hubble

Panning on Interacting Galaxies Arp 87 | Hubble

Panning on a stunning pair of interacting galaxies called Arp 87. Stars, gas, and dust flow from the large spiral galaxy, NGC 3808, forming an enveloping arm around its companion. The shapes of both galaxies have been distorted by their gravitational interaction. Arp 87 is located in the constellation of Leo, the Lion, approximately 300 million light-years away from Earth. 

Arp 87 appears in Arp's Atlas of Peculiar Galaxies. As also seen in similar interacting galaxies, the corkscrew shape of the tidal material suggests that some stars and gas drawn from the larger galaxy have been caught in the gravitational pull of the smaller one. This image was taken in February 2007 with Hubble's Wide Field Planetary Camera 2 detector.

Clouds can tell us a lot about what weather we might expect to see, but they are actually quite mysterious. The question is: Because clouds are produced by the climate, how will a changing climate impact clouds? And, conversely, clouds have an impact on our climate, so how will changing clouds affect a changing climate? Welcome to Clouds 101!

The Vela Supernova Remnant | European Southern Observatory (ESO)

The Vela Supernova Remnant | European Southern Observatory (ESO)

This beautiful structure is what remains of a massive star that ended its life with a supernova explosion some 11,000 years ago. The core of the star collapsed, forming a pulsar, while the outermost layers were ejected into the interstellar medium, producing the filaments that we still observe. This supernova remnant is located some 800 light years away, in the southern constellation of Vela (The Sails). The astrophotograph was taken from the European Southern Observatory's La Silla Observatory.

Standout Stars: Globular Cluster NGC 3201 | Hubble

Standout Stars: Globular Cluster NGC 3201 | Hubble

This image from the NASA/European Space Agency Hubble Space Telescope reveals a glistening and ancient globular cluster named NGC 3201—a gathering of hundreds of thousands of stars bound together by gravity. NGC 3201 was discovered in 1826 by the Scottish astronomer James Dunlop, who described it as a “pretty large, pretty bright” object that becomes “rather irregular” towards its center.

Distance: 16,000 light years

Globular clusters are found around all large galaxies, but their origin and role in galaxy formation remains unclear. Astronomers recently discovered a black hole lurking at the heart of NGC 3201—its position was revealed by the strange movements of a star being quickly flung around a massive, invisible counterpart. This sparkling group of stars also has some strange properties which make it unique among the over 150 globular clusters belonging to the Milky Way. NGC 3201 has an extremely fast velocity with respect to the Sun and its orbit is retrograde, meaning that it moves speedily in the opposite direction to the galactic center, which it orbits.

The unusual behavior of this cluster suggests that it may have extragalactic origins, but at some point was captured by the Milky Way’s gravity. However, the chemical makeup of this intriguing cluster tells a different story—the stars within NGC 3201 are chemically very similar to those of other galactic globular clusters, implying that they formed at a similar location and time to their neighbors.

Whether this mysterious cluster was adopted by our galaxy or has for some reason evolved very differently to the family of clusters it grew up with, it is certainly an unusual astronomical beauty.

China's Mengtian Lab Research Module Docking Succesful | China Space Station

China's Mengtian Lab Research Module Docking Succesful | China Space Station

Mengtian, the second lab module and the last major component of China's space station, docked with the front port of the Tianhe core module at 4:27 a.m (Beijing Time) Tuesday, November 1, 2022, after entering the planned orbit, according to the China Manned Space Agency. The Mengtian Laboratory Module (梦天实验舱, “Dreaming of Heavens”) is the second Laboratory Module of the China Space Station. It took approximately 13 hours for the entire process of rendezvous and docking.

The module is similar to Tianhe and Wentian in size and weight. It is 17.9 meters long, with a maximum diameter of 4.2 meters and a takeoff mass of about 23 tons. It consists of a working cabin for astronauts/taikonauts, an airlock cabin, a payload cabin and a resource cabin. Mengtian is mainly designed for scientific experiments. Unlike Tianhe and Wentian, it does not have a sleeping cabin. Instead, it is full of cabinets that can support hundreds of experiments.

The module will focus on microgravity scientific research. It is equipped with multi-disciplinary laboratory cabinets for experiments of fluid physics, materials and combustion science, basic physics and aerospace technology.
