Intense Aurora Borealis over Scotland

Intense Aurora Borealis over Scotland

On Earth, auroras are mainly created by particles originally emitted by the Sun in the form of solar wind. When this stream of electrically charged particles gets close to our planet, it interacts with the magnetic field, which acts as a gigantic shield. While it protects Earth’s environment from solar wind particles, it can also trap a small fraction of them. Particles trapped within the magnetosphere—the region of space surrounding Earth in which charged particles are affected by its magnetic field—can be energized and then follow the magnetic field lines down to the magnetic poles. There, they interact with oxygen and nitrogen atoms in the upper layers of the atmosphere, creating the flickering, colorful lights visible in the polar regions here on Earth

Earth auroras have different names depending on which pole they occur at. Aurora Borealis, or the northern lights, is the name given to auroras around the north pole and Aurora Australis, or the southern lights, is the name given for auroras around the south pole.

Venus over BlackGEM Telescopes in Chile | European Southern Observatory

Venus over BlackGEM Telescopes in Chile | European Southern Observatory

This image shows Venus shining bright in the night sky at the center of the picture. Around Venus is a weak light, and below Venus is an orange glow that comes from the rising Sun. The night sky takes up about two thirds of the upper part of the image, and is sprinkled with stars. In the lower part of the image is a road that leads to several telescopes. There are three dome shaped telescopes on pillars as well as one larger telescope to the left of the road. At the horizon, to the right, a telescope dome can be seen on top of a mountain. It is far away in the distance.

In this Picture of the Week, Venus is shining brightly over the European Southern Observatory’s La Silla Observatory in Chile. The picture was taken just before dawn, towards the East, and also features the diffuse zodiacal light—sunlight scattered by dust particles in the Solar System.

The three domes to the left of the road are the BlackGEM telescopes, built by Radboud University, the Netherlands Research School for Astronomy (NOVA), and KU Leuven. BlackGEM will search for the afterglow of some of the most dramatic events in the Universe, such as the collision of black holes and neutron stars. The ripples in space and time generated by these violent events can be detected by the LIGO and Virgo observatories. Thanks to their large field of view, the BlackGEM telescopes can locate the source of visible light from the afterglow of these events, and thereby pinpoint where the collision took place. This allows astronomers to study in greater detail what happens when black holes and neutron stars merge.

Galactic Seascape: Jellyfish Galaxy JO201 | Hubble

Galactic Seascape: Jellyfish Galaxy JO201 | Hubble

A jellyfish galaxy with trailing tentacles of stars hangs in inky blackness in this image from the NASA/European Space Agency Hubble Space Telescope. As Jellyfish galaxies move through intergalactic space they are slowly stripped of gas, which trails behind the galaxy in tendrils illuminated by clumps of star formation. These blue tendrils are visible drifting below the core of this galaxy, and give it its jellyfish-like appearance. This particular jellyfish galaxy—known as JO201—lies in the constellation Cetus, which is named after a sea monster from ancient Greek mythology. This sea-monster-themed constellation adds to the nautical theme of this image.

Image Description: A spiral galaxy lies just off-center. It has large, faint, reddish spiral arms and a bright, reddish core. These lie over two brighter blue spiral arms. These are patchy, with blotches of star formation. Long trails of these bright blotches trail down from the lower spiral arm, resembling tendrils. The background is black, lightly scattered with small galaxies and stars, and a larger elliptical galaxy in one corner.

The tendrils of jellyfish galaxies extend beyond the bright disc of the galaxy core. This particular observation comes from an investigation into the sizes, masses and ages of the clumps of star formation in the tendrils of jellyfish galaxies. Astronomers hope that this will provide a breakthrough in understanding the connection between ram-pressure stripping—the process that creates the tendrils of jellyfish galaxies—and star formation.

This galactic seascape was captured by Wide Field Camera 3 (WFC3), a versatile instrument that captures images at ultraviolet and visible wavelengths. WFC3 is the source of some of Hubble’s most spectacular images, from a view of Jupiter and Europa to a revisit to the Pillars of Creation.

Star-Forming Chamaeleon Cloud I | Hubble

Star-Forming Chamaeleon Cloud I | Hubble

This NASA Hubble Space Telescope image captures one of three segments that comprise a 65-light-year wide star-forming region named the Chamaeleon Cloud Complex. The segment in this Hubble composite image, called Chamaeleon Cloud I (Cha I), reveals dusty-dark clouds where stars are forming, dazzling reflection nebulae glowing by the light of bright-blue young stars, and radiant knots called Herbig-Haro objects.

Herbig-Haro objects are bright clumps and arcs of interstellar gas shocked and energized by jets expelled from infant “protostars” in the process of forming. The white-orange cloud at the bottom of the image hosts one of these protostars at its center. Its brilliant white jets of hot gas are ejected in narrow torrents from the protostar’s poles, creating the Herbig-Haro object HH 909A.

Image Description: Bright blue and white nebula with bright young blue stars dotted through the image. Bottom center: Herbig-Haro object, bright white clouds extend left and right, center point is white with rusty margins

The cross-like spikes around bright stars in the image occur when light waves from a very bright point source (like a star) bend around Hubble’s cross-shaped struts that support the telescope’s secondary mirror. As the light waves pass these struts, they coalesce on the other side, creating the bright, spikey starburst effect we see.

Hubble studied Cha I as part of a search for extremely dim, low-mass brown dwarfs. These “failed stars” lie somewhere in size between a large planet and a small star (10 to 90 times the mass of Jupiter), and do not have enough mass to ignite and sustain nuclear fusion in their cores. Hubble’s search found six new low-mass brown dwarf candidates that are helping astronomers better understand these objects.

This 315-million-pixel composite image is comprised of 23 observations made by Hubble’s Advanced Camera for Surveys. Gaps between those observations were filled by 20 Wide Field and Planetary Camera 2 images. Any remaining gaps were filled with ground-based data from the European Southern Observatory's VISTA VIRCAM.

Sparkling Spray of Stars in Open Cluster NGC 2660 | Hubble

Sparkling Spray of Stars in Open Cluster NGC 2660 | Hubble

This glittering group of stars, shining through the darkness like sparks left behind by a firework, is NGC 2660 in the constellation Vela, best viewed in the southern sky. NGC 2660 is an open cluster, a type of star cluster that can contain anywhere from tens to a few hundreds of stars loosely bound together by gravity. The stars of open clusters form out of the same region of gas and dust and thus share many characteristics, such as age and chemical composition. Unlike globular clusters—their ancient, denser, and more tightly-packed cousins—open clusters are easier to study since astronomers can more easily distinguish between individual stars. Their stars can be old or young, and they may disperse after a few million years into the spiral or irregular galaxies where they are born.

Image Description: Bright blue-white stars fill the scene, but are concentrated on the right side of the image. A bright reddish-orange star sits in the upper left quadrant of the image near image center.

The spikes surrounding many of the stars in this image are “diffraction spikes,” which occur when the glow from bright points of light reflects off of Hubble's secondary mirror support. The bright red object to the left with the very prominent diffraction spikes is a foreground star that is not part of the cluster. Hubble observed this open cluster as part of a program to study the ages of white dwarf stars in open clusters.

NASA's Artemis II Moon Rocket Engine Moved into Position for Final Join

NASA's Artemis II Moon Rocket Engine Moved into Position for Final Join

Technicians at NASA's Michoud Assembly Facility (MAF) in New Orleans, Louisiana, moved the engine section of NASA's Space Launch System (SLS) rocket for Artemis II, the first crewed mission to the Moon, into position for the final join of the core stage Feb. 22. The engine section is the bottom-most portion of the 212-foot-tall core stage. It is the last of five major elements that is needed to connect the stage into one major structure. In addition to its miles of cabling and hundreds of sensors, the engine section is a crucial attachment point for the four RS-25 engines and two solid rocket boosters that produce a combined 8.8 million pounds of thrust at liftoff and flight. During launch and flight, liquid propellants from the liquid hydrogen tank and liquid oxygen tanks are delivered through the engine section to the four RS-25 engines. The engine section also includes the avionics that help steer the engines after liftoff.

Next, teams will join the engine section to the core stage for the second SLS rocket. After the join is complete, teams will begin to add each of the four RS-25 engines one by one to complete the stage. The completely assembled stage with its four RS-25 engines will be shipped to NASA's Kennedy Space Center in Florida later this year. The SLS rocket is the only rocket capable of carrying astronauts in Orion around the Moon in a single mission.

NACA to NASA to Now: The Frontiers of Air and Space in the American Century tells the story of the National Advisory Committee for Aeronautics (NACA) and its successor, the National Aeronautics and Space Administration (NASA). The NACA and NASA facilitated the advance of technology for flight in air and space throughout the 20th and into the 21st century. This book explores how and why aerospace technology took the course it did, discusses some of the key people who drove aerospace science and technology development, and examines the political, economic, managerial, international, and cultural contexts in which the events of flight have unfolded.

The U.S. government explicitly challenged the NACA in 1915 to accelerate aeronautical research and to further the capability of the United States to push back the frontiers of flight. After more than 40 years of groundbreaking research into the problems of flight, the NACA was transformed in 1958 into NASA and given the added task of pursuing spaceflight with both humans and robots.

This fascinating work, written by Roger D. Launius, former NASA Chief Historian and Associate Director for Collections and Curatorial Affairs at the Smithsonian Institution’s National Air and Space Museum, illuminates the storied, multifaceted history of this agency in a single concise volume. It will serve as an excellent introduction and resource for NASA employees, journalists, scholars, and the general public to understand NASA’s rich heritage.
