Bright at infrared wavelengths, this merging galaxy pair is some 500 million light-years away toward the constellation Delphinus. The cosmic mashup is seen against a background of even more distant galaxies, and occasional spiky foreground stars. But the galaxy merger itself spans about 100,000 light-years in this deep James Webb Space Telescope image. The image data is from Webb's Near-InfraRed Camera (NIRCam) and Mid-InfraRed Instrument (MIRI). Their combined, sharp infrared view follows galactic scale restructuring in the dusty merger's wild jumble of intense star forming regions and distorted spiral arms

Bright blue-white cloud with a black keyhole-shaped void in the middle. Edge of the blue-white cloud transitions to brownish-rusty colored cloud.

This peculiar portrait from the NASA/ESA Hubble Space Telescope showcases NGC 1999, a reflection nebula in the constellation Orion. NGC 1999 is around 1,350 light-years from Earth and lies near the Orion Nebula, the closest region of massive star formation to Earth. NGC 1999 itself is a relic of recent star formation – it is composed of debris left over from the formation of a newborn star.

Just like fog curling around a streetlamp, reflection nebulae like NGC 1999 shine by the light from an embedded source. In the case of NGC 1999, this source is the aforementioned newborn star V380 Orionis, which is visible at the center of this image. The most notable aspect of NGC 1999’s appearance, however, is the conspicuous hole in its center, which resembles an inky black keyhole of cosmic proportions.

This image was created from archival Wide Field Planetary Camera 2 observations that date from shortly after Servicing Mission 3A in 1999. At the time, astronomers believed that the dark patch in NGC 1999 was something called a Bok globule – a dense, cold cloud of gas, molecules, and cosmic dust that blots out background light. However, follow-up observations using a collection of telescopes, including ESA’s Herschel Space Observatory, revealed that the dark patch is actually an empty region of space. The origin of this unexplained rift in the heart of NGC 1999 remains unknown.

2 wispy, light blue, gas clouds: HH 1 upper right, HH 2 lower left. Both surrounded by dimmer, multi-colored clouds with dark-black background. Very bright orange star lower left of HH 1. Beyond that star, narrow jet emerging from the dark image center.

The lives of newborn stars are tempestuous, as this image of the Herbig-Haro objects HH 1 and HH 2 from the NASA/ESA Hubble Space Telescope depicts. Both objects are in the constellation Orion and lie around 1,250 light-years from Earth. HH 1 is the luminous cloud above the bright star in the upper right of this image, and HH 2 is the cloud in the bottom left. While both Herbig-Haro objects are visible, the young star system responsible for their creation is lurking out of sight, swaddled in the thick clouds of dust at the center of this image. However, an outflow of gas from one of these stars is streaming out from the central dark cloud and is visible as a bright jet. Astronomers once thought the bright star between that jet and the HH 1 cloud was the source of these jets, but it is an unrelated double star that formed nearby.

Herbig-Haro objects are glowing clumps found around some newborn stars. They form when jets of gas thrown outwards from these young stars collide with surrounding gas and dust at incredibly high speeds. In 2002, Hubble observations revealed that parts of HH 1 are moving at more than 248 miles (400 kilometers) per second!

Hubble’s Wide Field Camera 3 captured this turbulent stellar nursery using 11 different filters at infrared, visible, and ultraviolet wavelengths. Each of these filters is sensitive to just a small slice of the electromagnetic spectrum, and they allow astronomers to pinpoint interesting processes that emit light at specific wavelengths.

In the case of HH 1 and 2, two groups of astronomers requested Hubble observations for two different studies. The first delved into the structure and motion of the Herbig-Haro objects visible in this image, giving astronomers a better understanding of the physical processes occurring when outflows from young stars collide with surrounding gas and dust. The second study investigated the outflows themselves to lay the groundwork for future observations with the NASA/ESA/CSA James Webb Space Telescope. Webb, with its ability to peer past the clouds of dust enveloping young stars, will revolutionize the study of outflows from young stars.

Technicians stack the JPSS-2 satellite atop the LOFTID spacecraft inside the Astrotech Space Operations facility at Vandenberg Space Force Base in California on Oct. 5, 2022.

Preparations continue for the launch of the National Oceanic and Atmospheric Administration’s (NOAA) Joint Polar Satellite System-2 (JPSS-2) satellite. On Tuesday, Oct. 4, JPSS-2 was attached to its payload adapter inside the Astrotech Space Operations facility at Vandenberg Space Force Base in California. On Wednesday, Oct. 5, technicians and engineers completed the mate process using a crane to lift JPSS-2 and attach it to the top of the stack containing the re-entry vehicle for the Low-Earth Orbit Flight Test of an Inflatable Decelerator, or LOFTID, technology demonstration.

To prepare LOFTID for stacking, technicians mated the re-entry vehicle payload adapter interface ring to LOFTID inside Building 836 at Vandenberg. Then the team mated the payload adapter separation system inside the re-entry vehicle payload adapter canister. Finally, technicians lifted the payload adapter canister over the re-entry vehicle to complete the stack. The LOFTID stack was moved to Astrotech to complete mating operations with JPSS-2.

Next up, the assembly will be encapsulated in a protective payload fairing. After encapsulation, the team will transport the encapsulated spacecraft to Space Launch Complex-3 where a crane will hoist it up for attachment to the second stage of the United Launch Alliance Atlas V 401 rocket.

JPSS-2 and LOFTID together measure approximately 27 feet tall. Launch is targeted for Nov.1 from Vandenberg. NASA’s Launch Services Program, based at the agency’s Kennedy Space Center in Florida, is managing the launch.

“As first-generation immigrants we have to figure things out on our own a lot of times. My parents were going through the same transition [to America] that I was going through [in high school]. We didn’t have a lot of direction. In order for me to get to the path that I’m on today, I had to figure a lot of things out on my own. Because I had to do it to survive, I think that that built into me some sense of independence and not being afraid of asking for help. I feel like those are some of my best skills, and they’ve been really useful for me in my career [as a NASA systems engineer].

“All throughout college, I worked as an English and math tutor for kids who were in a similar position as me: they’re in middle school or high school, they don't know a lot of English, and they don't know how to navigate the system. Normally, most tutors are trying to help with homework, but when you’ve experienced what I experienced and you see similar things happening to them, your role as a tutor becomes a little bit more.

“A lot of people in similar positions as myself, we struggle a lot with confidence and imposter syndrome. But having enough confidence to say, ‘I can do this. I’m ready, and even if I am not ready, I can be ready’ [is important]. I try to help people see that there’s an opportunity, and that if you work hard and are willing to evoke whatever it takes to get there, you can get it.

“It’s been a lot of delayed gratification because seven years ago I started as an intern, we launch [Europa Clipper] in 2024, and then it will be five years until we arrive at the Jupiter system. But I like that stuff. It’s a lot of work, but whatever we get out of [this mission] has the potential to change our understanding of who we are, and that’s really motivating for me.”

“It makes me feel like I am working towards a greater goal, and there’s no substitute to that. I could easily go work with another company, but I don't think I would be able to find this extremely important, humanity scale-type of investigation anywhere else.”

On September 28, the Landsat 8 satellite passed directly over Hurricane Ian’s eye as the storm approached southwest Florida.

The Operational Land Imager aboard the Landsat 8 satellite captured this natural-color image of Hurricane Ian’s eye on Sept. 28, 2022 at 11:57 a.m. EDT (15:57 UTC), three hours before the storm crashed into the coast in Caya Costa, Fla.

When Ian’s eyewall made landfall, its maximum sustained winds were 150 miles (240 kilometers) per hour, according to the National Hurricane Center. That is the equivalent of a category 4 storm on the Saffir-Simpson wind scale and fast enough to tear the roofs off homes and snap power lines.

The eye of a hurricane is a circular zone of fair weather at the storm’s center. It is surrounded by a towering ring of extremely powerful thunderstorms called an eyewall, the part of the hurricane with the strongest winds. The swirling clouds along the edges of the eyewall are mesovortices—small-scale rotational features found in hurricanes with unusually strong winds.

bright spiral galaxy fills the scene. Dark reddish-brown dust lanes bisect the spiral arms. Bright blue stars are dotted troughout.

The galaxy NGC 1961 unfurls its gorgeous spiral arms in this newly released image from NASA’s Hubble Space Telescope. Glittering, blue regions of bright young stars dot the dusty spiral arms winding around the galaxy’s glowing center.

NGC 1961 is an intermediate spiral and an AGN, or active galactic nuclei, type of galaxy. Intermediate spirals are in between “barred” and “unbarred” spiral galaxies, meaning they don’t have a well-defined bar of stars at their centers. AGN galaxies have very bright centers that often far outshine the rest of the galaxy at certain wavelengths of light. These galaxies likely have supermassive black holes at their cores churning out bright jets and winds that shape their evolution. NGC 1961 is a fairly common type of AGN that emits low-energy-charged particles.

The data used to create this image came from two proposals. One studied previously unobserved Arp galaxies, while the other looked at the progenitors and explosions of a variety of supernovae.

Located about 180 million light-years away, NGC 1961 resides in the constellation Camelopardalis.

Voyager 1 and Voyager 2 were launched in 1977 on a grand tour of the outer planets of the Solar System. They have become the longest operating and most distant spacecraft from Earth. Both have traveled beyond the heliosphere, the realm defined by the influence of the solar wind and the Sun's magnetic field. On the 45th year of their journey toward the stars Voyager 1 and 2 reached nearly 22 light-hours and 18 light-hours from the Sun respectively and remain the only spacecraft currently exploring interstellar space. Each spacecraft carries a 12-inch gold-plated copper disk with recordings of sounds, pictures and messages. The Golden Records are intended to communicate a story of life and culture on planet Earth, preserved in a medium that can survive an interstellar journey for a billion years.

Bright-white stars in a cloud of blue. Superimposed on the scene is a red spiral.

Nature likes spirals – from the whirlpool of a hurricane, to pinwheel-shaped protoplanetary disks around newborn stars, to the vast realms of spiral galaxies across our universe.

Now astronomers are bemused to find young stars that are spiraling into the center of a massive cluster of stars in the Small Magellanic Cloud, a satellite galaxy of the Milky Way.

The outer arm of the spiral in this huge, oddly shaped stellar nursery called NGC 346 may be feeding star formation in a river-like motion of gas and stars. This is an efficient way to fuel star birth, researchers say.

The massive star cluster NGC 346, located in the Small Magellanic Cloud, has long intrigued astronomers with its unusual shape. Now researchers using two separate methods have determined that this shape is partly due to stars and gas spiraling into the center of this cluster in a river-like motion. The red spiral superimposed on NGC 346 traces the movement of stars and gas toward the center. Scientists say this spiraling motion is the most efficient way to feed star formation from the outside toward the center of the cluster.

The Small Magellanic Cloud has a simpler chemical composition than the Milky Way, making it similar to the galaxies found in the younger universe, when heavier elements were more scarce. Because of this, the stars in the Small Magellanic Cloud burn hotter and so run out of their fuel faster than in our Milky Way.

Though a proxy for the early universe, at 200,000 light-years away the Small Magellanic Cloud is also one of our closest galactic neighbors.

Learning how stars form in the Small Magellanic Cloud offers a new twist on how a firestorm of star birth may have occurred early in the universe's history, when it was undergoing a "baby boom" about 2 to 3 billion years after the big bang (the universe is now 13.8 billion years old).

"The Hubble archive is really a gold mine. There are so many interesting star-forming regions that Hubble has observed over the years. Given that Hubble is performing so well, we can actually repeat these observations. This can really advance our understanding of star formation."

--Elena Sabbi, STScI

The new results find that the process of star formation there is similar to that in our own Milky Way.

Only 150 light-years in diameter, NGC 346 boasts the mass of 50,000 Suns. Its intriguing shape and rapid star formation rate has puzzled astronomers. It took the combined power of NASA's Hubble Space Telescope and the European Southern Observatory's Very Large Telescope (VLT) to unravel the behavior of this mysterious-looking stellar nesting ground.

"Stars are the machines that sculpt the universe. We would not have life without stars, and yet we don't fully understand how they form," explained study leader Elena Sabbi of the Space Telescope Science Institute in Baltimore. "We have several models that make predictions, and some of these predictions are contradictory. We want to determine what is regulating the process of star formation, because these are the laws that we need to also understand what we see in the early universe."

Researchers determined the motion of the stars in NGC 346 in two different ways. Using Hubble, Sabbi and her team measured the changes of the stars' positions over 11 years. The stars in this region are moving at an average velocity of 2,000 miles per hour, which means that in 11 years they move 200 million miles. This is about 2 times the distance between the Sun and the Earth.

But this cluster is relatively far away, inside a neighboring galaxy. This means the amount of observed motion is very small and therefore difficult to measure. These extraordinarily precise observations were possible only because of Hubble's exquisite resolution and high sensitivity. Also, Hubble's three-decade-long history of observations provides a baseline for astronomers to follow minute celestial motions over time.

The second team, led by Peter Zeidler of AURA/STScI for the European Space Agency, used the ground-based VLT's Multi Unit Spectroscopic Explorer (MUSE) instrument to measure radial velocity, which determines whether an object is approaching or receding from an observer.

"What was really amazing is that we used two completely different methods with different facilities and basically came to the same conclusion, independent of each other," said Zeidler. "With Hubble, you can see the stars, but with MUSE we can also see the gas motion in the third dimension, and it confirms the theory that everything is spiraling inwards."

But why a spiral?

"A spiral is really the good, natural way to feed star formation from the outside toward the center of the cluster," explained Zeidler. "It's the most efficient way that stars and gas fueling more star formation can move towards the center."

Half of the Hubble data for this study of NGC 346 is archival. The first observations were taken 11 years ago. They were recently repeated to trace the motion of the stars over time. Given the telescope's longevity, the Hubble data archive now contains more than 32 years of astronomical data powering unprecedented, long-term studies.

"The Hubble archive is really a gold mine," said Sabbi. "There are so many interesting star-forming regions that Hubble has observed over the years. Given that Hubble is performing so well, we can actually repeat these observations. This can really advance our understanding of star formation."

The teams' findings appear Sept. 8 in The Astrophysical Journal.

Observations with NASA's James Webb Space Telescope should be able to resolve lower-mass stars in the cluster, giving a more holistic view of the region. Over Webb's lifespan, astronomers will be able to repeat this experiment and measure the motion of the low-mass stars. They could then compare the high-mass stars and the low-mass stars to finally learn the full extent of the dynamics of this nursery.

Once upon a space-time, a cosmic creation story unfolded: Thousands of never-before-seen young stars spotted in a stellar nursery called 30 Doradus, captured by NASA’s James Webb Space Telescope. Nicknamed the Tarantula Nebula for the appearance of its dusty filaments in previous telescope images, the nebula has long been a favorite for astronomers studying star formation. In addition to young stars, Webb reveals distant background galaxies, as well as the detailed structure and composition of the nebula’s gas and dust.

At only 161,000 light-years away in the Large Magellanic Cloud galaxy, the Tarantula Nebula is the largest and brightest star-forming region in the Local Group, the galaxies nearest our Milky Way. It is home to the hottest, most massive stars known. Astronomers focused three of Webb’s high-resolution infrared instruments on the Tarantula. Viewed with Webb’s Near-Infrared Camera (NIRCam), the region resembles a burrowing tarantula’s home, lined with its silk. The nebula’s cavity centered in the NIRCam image has been hollowed out by blistering radiation from a cluster of massive young stars, which sparkle pale blue in the image. Only the densest surrounding areas of the nebula resist erosion by these stars’ powerful stellar winds, forming pillars that appear to point back toward the cluster. These pillars contain forming protostars, which will eventually emerge from their dusty cocoons and take their turn shaping the nebula.

Webb’s Near-Infrared Spectrograph (NIRSpec) caught one very young star doing just that. Astronomers previously thought this star might be a bit older and already in the process of clearing out a bubble around itself. However, NIRSpec showed that the star was only just beginning to emerge from its pillar and still maintained an insulating cloud of dust around itself. Without Webb’s high-resolution spectra at infrared wavelengths, this episode of star formation-in-action could not have been revealed.

The region takes on a different appearance when viewed in the longer infrared wavelengths detected by Webb’s Mid-infrared Instrument (MIRI). The hot stars fade, and the cooler gas and dust glow. Within the stellar nursery clouds, points of light indicate embedded protostars, still gaining mass. While shorter wavelengths of light are absorbed or scattered by dust grains in the nebula, and therefore never reach Webb to be detected, longer mid-infrared wavelengths penetrate that dust, ultimately revealing a previously unseen cosmic environment. 

One of the reasons the Tarantula Nebula is interesting to astronomers is that the nebula has a similar type of chemical composition as the gigantic star-forming regions observed at the universe’s “cosmic noon,” when the cosmos was only a few billion years old and star formation was at its peak. Star-forming regions in our Milky Way galaxy are not producing stars at the same furious rate as the Tarantula Nebula, and have a different chemical composition. This makes the Tarantula the closest (i.e., easiest to see in detail) example of what was happening in the universe as it reached its brilliant high noon. Webb will provide astronomers the opportunity to compare and contrast observations of star formation in the Tarantula Nebula with the telescope’s deep observations of distant galaxies from the actual era of cosmic noon.

Despite humanity’s thousands of years of stargazing, the star-formation process still holds many mysteries – many of them due to our previous inability to get crisp images of what was happening behind the thick clouds of stellar nurseries. Webb has already begun revealing a universe never seen before, and is only getting started on rewriting the stellar creation story.  

The James Webb Space Telescope is the world's premier space science observatory. Webb will solve mysteries in our solar system, look beyond to distant worlds around other stars, and probe the mysterious structures and origins of our universe and our place in it. Webb is an international program led by NASA with its partners, ESA (European Space Agency) and the Canadian Space Agency.

Hubble image of a star and galaxy in Lacerta

A little-studied star, TYC 3203-450-1, upstages a galaxy in this Hubble Telescope image from December 2017. Both the star and the galaxy are within the Lizard constellation, Lacerta. However, the star is much closer than the much more distant galaxy.

Astronomers studying distant objects call these stars “foreground stars” and they are often not very happy about them, as their bright light is contaminating the faint light from the more distant and interesting objects they actually want to study.
