NASA's Lucy Mission Flyby of Asteroid Dinkinesh | NASA Goddard

NASA's Lucy Mission Flyby of Asteroid Dinkinesh | NASA Goddard

On Nov. 1, 2023, NASA's Lucy spacecraft will fly by the small Main Belt asteroid Dinkinesh (previously known as 1999 VD57). This asteroid flyby was added to Lucy’s list of targets in January 2023. The primary purpose of the Dinkinesh encounter is to test the spacecraft’s Terminal Tracking System, which will keep Lucy's instruments pointing at the asteroid as it flies by at 10,000 miles per hour. The Lucy mission’s record-breaking tour will now explore at least ten small solar system bodies. 

Lucy will have the close approach with Dinkinesh as the spacecraft skims the inner edge of the main asteroid belt. After the encounter, Lucy will head back towards Earth for its second gravity assist in December 2024. That assist will send the spacecraft to explore the Jupiter Trojan asteroids.

Planet Jupiter's Atmosphere: A High Speed Jet Stream Detected | NASA Webb

Planet Jupiter's Atmosphere: A High Speed Jet Stream Detected | NASA Webb

This image of Jupiter from NASA’s James Webb Space Telescope’s NIRCam (Near-Infrared Camera) shows stunning details of the majestic planet in infrared light. In this image, brightness indicates high altitude. The numerous bright white "spots" and "streaks" are likely very high-altitude cloud tops of condensed convective storms. Auroras, appearing in red in this image, extend to higher altitudes above both the northern and southern poles of the planet. By contrast, dark ribbons north of the equatorial region have little cloud cover.
In Webb’s images of Jupiter from July 2022, researchers recently discovered a narrow jet stream traveling 320 miles per hour (515 kilometers per hour) sitting over Jupiter’s equator above the main cloud decks.

Researchers using NASA’s James Webb Space Telescope’s NIRCam (Near-Infrared Camera) have discovered a high-speed jet stream sitting over Jupiter’s equator, above the main cloud decks. At a wavelength of 2.12 microns, which observes between altitudes of about 12-21 miles (20-35 kilometers) above Jupiter’s cloud tops, researchers spotted several wind shears, or areas where wind speeds change with height or with distance, which enabled them to track the jet. This image highlights several of the features around Jupiter’s equatorial zone that, between one rotation of the planet (10 hours), are very clearly disturbed by the motion of the jet stream.

Auroras, appearing in red in this image, extend to higher altitudes above both the northern and southern poles of the planet. By contrast, dark ribbons north of the equatorial region have little cloud cover.

NASA’s James Webb Space Telescope has discovered a new, never-before-seen feature in Jupiter’s atmosphere. The high-speed jet stream, which spans more than 3,000 miles (4,800 kilometers) wide, sits over Jupiter’s equator above the main cloud decks. The discovery of this jet is giving insights into how the layers of Jupiter’s famously turbulent atmosphere interact with each other, and how Webb is uniquely capable of tracking those features.

“This is something that totally surprised us,” said Ricardo Hueso of the University of the Basque Country in Bilbao, Spain, lead author on the paper describing the findings. “What we have always seen as blurred hazes in Jupiter’s atmosphere now appear as crisp features that we can track along with the planet’s fast rotation.”

In Webb’s images of Jupiter from July 2022, researchers recently discovered a narrow jet stream traveling 320 miles per hour (515 kilometers per hour) sitting over Jupiter’s equator above the main cloud decks.

While Jupiter is different from Earth in many ways–Jupiter is a gas giant, Earth is a rocky, temperate world–both planets have layered atmospheres. Infrared, visible, radio, and ultraviolet-light wavelengths observed by these other missions detect the lower, deeper layers of the planet’s atmosphere–where gigantic storms and ammonia ice clouds reside.

“Jupiter has a complicated but repeatable pattern of winds and temperatures in its equatorial stratosphere, high above the winds in the clouds and hazes measured at these wavelengths,” explained team member Leigh Fletcher of the University of Leicester in the United Kingdom. “If the strength of this new jet is connected to this oscillating stratospheric pattern, we might expect the jet to vary considerably over the next 2 to 4 years – it’ll be really exciting to test this theory in the years to come.”

While Webb’s exquisite resolution and wavelength coverage allowed for the detection of small cloud features used to track the jet, the complementary observations from Hubble taken one day after the Webb observations were also crucial to determine the base state of Jupiter’s equatorial atmosphere and observe the development of convective storms in Jupiter’s equator not connected to the jet.  

The researchers’ results were recently published in Nature Astronomy:

Stellar Layers of a Galactic Onion: Shell Galaxy NGC 3923 | NOIRLab

Stellar Layers of a Galactic Onion: Shell Galaxy NGC 3923 | NOIRLab

Cosmoview Episode 73: The symmetrical, onion-like layers of shell galaxy NGC 3923 are showcased in this galaxy-rich image taken by the US Department of Energy’s (DOE) Dark Energy Camera mounted on the National Science Foundation’s (NSF) Víctor M. Blanco 4-meter Telescope at Cerro Tololo Inter-American Observatory in Chile, a Program of NSF’s NOIRLab. A nearby, massive galaxy cluster is also captured exhibiting the phenomenon known as gravitational lensing.

Much like humans, galaxies are shaped by the environment in which they form. While no two are exactly alike, they can be divided into three main types: spiral, elliptical and irregular. Of these types, elliptical galaxies are the largest and are thought to evolve out of galactic collisions and mergers between spirals. About one-tenth of elliptical galaxies are classified as shell galaxies, characterized by the concentric shells that make up their galactic halos.

A striking example of this type of galaxy is NGC 3923, with its onion-like layers beautifully showcased in this image. Located in the constellation Hydra (the Serpent), NGC 3923 is about 70 million light-years away from Earth and 150,000 light-years across, making it about 50% larger than our Milky Way.

As is thought to be the story of all shell galaxies, the layered structure seen in NGC 3923 likely developed as a consequence of a merger with another, smaller spiral galaxy in the past. As they merged, the larger galaxy’s gravitational field slowly peeled off stars from the smaller galaxy’s disk. Those stars began to gradually mix with the larger galaxy’s outer halo, forming concentric bands, or shells. A simple analogy is adding a drop of food color to a bowl of batter that you’re slowly stirring. The drop gets stretched out in a spiral that remains visible for a long time before completely mixing.

The shells of NGC 3923 make the galaxy quite exceptional. Not only does it have the largest known shell of all observed shell galaxies, but it also has the largest number of shells and the largest ratio between the radii of the outermost and innermost shells. A 2016 study determined that NGC 3923 could be made up of as many as 42 distinct shells, with the outermost layers having been created first, followed by the innermost layers as the galaxies’ celestial dance slowed.

Another notable characteristic of NGC 3923 is that its shells are much more subtle than those of other shell galaxies. Its shells are also interestingly symmetrical, while other shell galaxies are more skewed. These uncommon features are a sublime example of the unique structures that galaxies can embody depending on their specific evolutionary conditions.

While NGC 3923 is certainly the main attraction in this expansive, 250-megapixel image, the longer one spends perusing the glittering field the more cosmic treasures can be found. Among the thousands of galaxies and countless foreground Milky Way stars speckling this image are the face-on spiral galaxies LEDA 744285 and ESO 440-11. And near the top of the image is the extremely large gravitational lens around galaxy cluster PLCK G287.0+32.9.

Discussed in scientific journals since the 1930s, gravitational lenses are predicted by Einstein’s General Theory of Relativity, which states that a massive object, such as a cluster of galaxies, can warp spacetime. Narrow arc-like shapes located around clusters of galaxies were first found in 1989 by NOIRLab (then NOAO) astronomer Roger Lynds and Stanford colleague Vahé Petrosian using the Nicholas U. Mayall 4-meter Telescope at Kitt Peak National Observatory, a Program of NSF’s NOIRLab. These extragalactic properties were interpreted as the result of strong gravitational lensing from distant galaxies in the background.

Indeed, when zoomed into this image, a handful of galaxies can be seen stretched out and distorted under the gravitational influence of dark matter, the mysterious substance found concentrated around clusters of galaxies. Gravitational lenses allow astronomers to explore the most profound questions of our Universe, including the nature of dark matter and the value of the Hubble constant, which defines the expansion of the Universe.

Colliding Galaxies in Pisces Up Close: NGC 520 | Hubble

Colliding Galaxies in Pisces Up Close: NGC 520 | Hubble


NGC 520 is the product of a collision between two disc galaxies that started 300 million years ago. It exemplifies the middle stages of the merging process. The discs of the parent galaxies have merged together, but the nuclei have not yet coalesced. It features an odd-looking tail of stars and a prominent dust lane that runs diagonally across the center of the image and obscures the galaxy. Distance: 100 million light years

NGC 520 is one of the brightest galaxy pairs on the sky, and can be observed with a small telescope toward the constellation of Pisces, the Fish, having the appearance of a comet. It is about 100 million light-years away and about 100,000 light-years across. The galaxy pair is included in Arp's catalogue of peculiar galaxies as ARP 157.

SpaceX Falcon Heavy Rocket Liftoff | NASA Psyche Asteroid Mission

SpaceX Falcon Heavy Rocket Liftoff | NASA Psyche Asteroid Mission









A SpaceX Falcon Heavy rocket successfully launched NASA’s Psyche Asteroid Mission spacecraft from Launch Complex 39A (LC-39A) at Kennedy Space Center in Florida, on Friday, October 13, 2023, at 10:19am EDT.

Following booster separation, Falcon Heavy’s two side boosters (B1064 and B1065) landed at SpaceX’s Landing Zones 1 and 2 (LZ-1 and LZ-2) at the Cape Canaveral Space Force Station in Florida, having previously supported USSF-44, USSF-67 and JUPITER 3. Due to mission requirements, the core booster (B1079) was not planned to be recovered. NASA’s Psyche spacecraft will study a metal-rich asteroid with the same name, located in the main asteroid belt between Mars and Jupiter. 

Destination: Only the 16th asteroid to be discovered, Psyche was found in 1852 by Italian astronomer Annibale de Gasparis, who named it for the goddess of the soul in ancient Greek mythology. It has a mean diameter of approximately 220 kilometers (140 mi) and contains about one percent of the mass of the asteroid belt.

What gives asteroid Psyche great scientific interest is that it is likely rich in metal. It may consist largely of metal from the core of a planetesimal, one of the building blocks of the Sun’s planetary system. At Psyche scientists will explore, for the first time ever, a world made not of rock or ice, but rich in metal.

The spacecraft is expected to begin orbiting the asteroid Psyche in 2029.

Arizona State University leads the Psyche mission. The Jet Propulsion Laboratory (JPL), managed for NASA by Caltech in Pasadena, California, is responsible for the mission’s overall management, system engineering, integration and test, and mission operations. Maxar is providing the high-power solar electric propulsion spacecraft chassis.

The Veil Nebula: The Dusty Western Side

Veil Nebula: The Dusty Western Side

It is so large, it is easy to miss. The entire Veil Nebula spans six times the diameter of the full moon, but it is so dim you need binoculars to see it. The nebula was created about 15,000 years ago when a star in the constellation of the Swan (Cygnus) exploded. The spectacular explosion would have appeared brighter than even Venus for a week—but there is no known record of it. Pictured is the western edge of the still-expanding gas cloud. Notable gas filaments include the Witch's Broom Nebula on the upper left near the bright foreground star 52 Cygni, and Fleming's Triangular Wisp (formerly known as Pickering's Triangle) running diagonally up the image middle. What is rarely imaged—but seen in the featured long exposure across many color bands—is the reflecting brown dust that runs vertically up the image left, dust likely created in the cool atmospheres of massive stars.

Earth Darkened by the Moon’s Shadow | Deep Space Climate Observatory

Earth Darkened by the Moon’s Shadow | Deep Space Climate Observatory


On October 14, 2023, the Moon aligned with the Sun and Earth to produce an annular solar eclipse. The spectacle bathed millions of Americans in a lunar shadow as the Moon blocked the Sun’s rays.

An annular eclipse occurs when the Moon passes in front of the Sun but is too far from Earth to completely obscure it. The Moon is at or near its farthest distance from Earth—known as its apogee—during an annular eclipse, making it look smaller in the sky. This leaves the Sun’s edges exposed in a red-orange ring, dubbed the “ring of fire.” A satellite caught an earthly view of the event, as the Moon’s shadow crossed North America.

This image was acquired during the eclipse by NASA’s Earth Polychromatic Imaging Camera (EPIC) imager aboard Deep Space Climate Observatory (DSCVR), a joint NASA, NOAA, and U.S. Air Force satellite. The sensor provides frequent global views of Earth from its position at Lagrange Point 1, a gravitationally stable point between the Sun and Earth about 1.5 million kilometers from Earth. In this view, acquired at 16:58 Universal Time (11:58 a.m. Central Daylight Time), the shadow, or umbra, from the Moon can be seen falling across the southeastern coast of Texas, near Corpus Christi.

While the annular eclipse was partially visible across the entire United States, Mexico, and countries in Central and South America, the path of annularity—where the largest area of the Sun was covered by the Moon from the observers' point of view—was the best place to view it.

The path of annularity started in Oregon around 9:13 a.m. Pacific Daylight Time, though cloudy skies blocked the view for some sky watchers. The shadow then moved southeast across Nevada, Utah, Arizona, Colorado, and New Mexico, before passing over Texas and the Gulf of Mexico.

The next annular solar eclipse visible from the United States will be on June 21, 2039. But a total solar eclipse will darken skies from Texas to Maine on Monday, April 8, 2024.

Dark Nebula LDN604 & GGD30 in Aquila | Schulman Telescope

Dark Nebula LDN604 & GGD30 in Aquila | Schulman Telescope

Dark nebulae—also called absorption nebulae—are clouds of gas and dust that neither emit nor reflect light, instead blocking light coming from behind them. These nebulae tend to contain large amounts of dust. This allows them to absorb visible light from stars or nebulae beyond them. Dark nebulae are so dark that they have been referred to as “holes in the sky,” but in reality they may be full of activity with stars sometimes forming inside their dense clouds.

Panning across the 'Rosy' Nebula IC1284 in Sagittarius | ESO

Panning across the 'Rosy' Nebula IC1284 in Sagittarius | ESO

This video sequence offers a close look at IC 1284, a nebula located about 5,500 light-years away in the constellation Sagittarius. In the center of a dark red background, the cloud of a bright red nebula glows. Meanwhile, in the bottom right corner, two smaller blue nebulae shine in contrast to the surrounding reddish hue. Dotted across the entire image, there are several large blue and white stars, as well as many faint white and yellow stars. 

There are two different types of nebulae present here. Each appears with a distinct color in the visible sky and are captured here using the wide-field camera OmegaCAM on the VLT Survey Telescope (VST), hosted at the European Southern Observatory’s Paranal Observatory in the Chilean desert.

The large, bright emission nebula at the center, IC1284, is a star-forming region composed primarily of hydrogen. Its rosy glow comes from electrons within the hydrogen atoms. They are excited by the radiation from young stars, but then they lose energy and emit a specific color or wavelength of light. One of the filters on OmegaCAM lets through this particular reddish color, hence the nebula’s look. 

Meanwhile, another color filter highlights the blue reflection nebulae NGC6589 and NGC6590 in the lower right corner. The dust in a reflection nebula preferentially scatters shorter, bluer wavelengths of light from nearby stars, which is what gives these nebulae their eerie glow. This is the same reason why the sky is blue!

The images in this video were collected by the VLT Survey Telescope (VST), which is owned by the Italian National Institute for Astrophysics (INAF) and hosted at the European Southern Observatory’s Paranal Observatory in Chile.
