Zooming in on Barnard’s Galaxy in Sagittarius | European Southern Observatory

Zooming in on Barnard’s Galaxy in Sagittarius | European Southern Observatory

Zooming in on Barnard’s Galaxy, also known as NGC 6822. The galaxy contains regions of rich star formation and curious nebulae, such as the bubble clearly visible in the upper left of this remarkable vista. Astronomers classify NGC 6822 as an irregular dwarf galaxy because of its odd shape and relatively diminutive size by galactic standards. The strange shapes of these cosmic "misfits" help researchers understand how galaxies interact, evolve and occasionally “cannibalise” each other, leaving behind radiant, star-filled scraps. Distance: 2 million light years

Barnard's Galaxy with Bubble-shaped Nebula in Sagittarius | ESO

Astronomers obtained this portrait of Barnard’s Galaxy using the Wide Field Imager attached to the 2.2-meter MPG/ESO telescope at the European Southern Observatory’s La Silla Observatory in northern Chile. The image was made from data obtained through four different filters (B, V, R, and H-alpha). The field of view is 35 x 34 arcmin.

This montage shows four star-forming gas clouds in NGC 6822, a barred irregular dwarf galaxy, about 1.6 million light-years away.  The observations were made with the Wide Field Imager attached to the 2.2-meter MPG/ESO telescope at ESO’s La Silla Observatory, the Very Large Array and by the Atacama Large Millimeter/submillimeter Array (ALMA).

This image is a composite of older observations made with the Wide Field Imager attached to the 2.2-meter MPG/ESO telescope at ESO’s La Silla Observatory and new data collected by the Atacama Large Millimeter/submillimeter Array (ALMA). The observations by ALMA reveal the structure of star-forming gas clouds in unprecedented resolution.

Known as NGC 6822, this dwarf irregular galaxy is one of the Milky Way’s galactic neighbors 2 million light years away. The dwarf galaxy has no shortage of stellar splendor and pyrotechnics. Reddish nebulae in this image reveal regions of active star formation, wherein young, hot stars heat up nearby gas clouds. Also prominent in the upper left of this new image is a striking bubble-shaped nebula. At the nebula’s center, a clutch of massive, scorching stars send waves of matter smashing into surrounding interstellar material, generating a glowing structure that appears ring-like from our perspective. Other similar ripples of heated matter thrown out by feisty young stars are dotted across Barnard’s Galaxy.

NASA Astronauts Frank Rubio and Woody Hoburg

Expedition 69 Flight Engineers Steve Bowen and Woody Hoburg of NASA concluded their spacewalk June 9, 2023, after 6 hours and 3 minutes.

Bowen and Hoburg completed all of their objectives to install an IROSA (International Space Station Roll-Out Solar Array) to augment power generation for the 1A power channel on the station’s starboard truss structure. The crew members also completed several get ahead tasks setting the stage for the duo to go back outside Thursday, June 15, to install the sixth in the series of IROSAs on the starboard 6 truss of the station for the 1B power channel.

The new arrays are 60 feet long by 20 feet wide (18.2 meters by 6 meters) and will shade a little more than half of the original arrays, which are 112 feet long by 39 feet wide. Each new IROSA will produce more than 20 kilowatts of electricity, and once all are installed, will enable a 30% increase in power production over the station’s current arrays.

It was the 264th spacewalk in support of space station assembly, upgrades, and maintenance, and was the third spacewalk for both astronauts.

Bowen and Hoburg are in the midst of a science mission living and working aboard the microgravity laboratory to advance scientific knowledge and demonstrate new technologies for future human and robotic exploration missions, including lunar missions through NASA’s Artemis program.

The Tadpoles Nebula: IC 410 | Canada-France-Hawaii Telescope

The Tadpoles Nebula: IC 410 | Canada-France-Hawaii Telescope

IC 410 is a dusty emission nebula located in the constellation of Auriga around 12,000 light years from Earth. It is part of a larger star forming region that also contains the Flaming Star Nebula. The gas structures in this picture are lit by the radiation from the open star cluster NGC1893 that lies in the center of the nebula. This star cluster is about 4 million years old, but in astronomical terms it is still very young, with hot, massive stars. At the center of the star cluster, two dense structures are visible. These are similar to the famous Pillar of Creation and they are composed of dust and gas leftover from the formation of the star cluster and are very likely to give birth to more stars in the future. As can be seen in the picture, these structures point away from the center of the nebula. This is because of the stellar winds and radiation pressure from the stars in NGC 1893. Due to these structure's shape, the nebula is also called the Tadpoles Nebula.

View Quasar J0100+2802 and over 20,000 Galaxies | James Webb Space Telescope

View Quasar J0100+2802 and over 20,000 Galaxies | James Webb Space Telescope

More than 20,000 tiny galaxies appear across the black background of space in this new James Webb Space Telescope image. At the center is a pink object with six diffraction spikes. This is quasar J0100+2802. A quasar is an extremely luminous active supermassive black hole that acts like an enormous flashlight. This one appears slightly smaller than the blue foreground stars. The galaxy colors here vary. Some of the smallest galaxies are shades of orange and pink. Most galaxies are so distant they appear as single points of light. Slightly larger, fuzzier galaxies appear whiter. Some have distinct spiral arms. In front of the galaxies are several foreground stars, though none appear larger than the largest galaxies. The foreground stars are scattered around the image, appear blue and have eight prominent diffraction spikes. 

The Webb Telescope team analyzed 117 galaxies that all existed approximately 900 million years after the big bang—focusing on 59 that lie in front of the quasar. The researchers could study not only the galaxies themselves, but also the illuminated gas surrounding them.   

These galaxies existed just before the end of the Era of Reionization, when the universe contained a patchwork of gas—some opaque and some transparent (or ionized). “As we look back into the teeth of reionization, we see a very distinct change,” explained Simon Lilly of ETH Zürich in Switzerland, who leads this team of researchers. “Galaxies, which are made up of billions of stars, are ionizing the gas around them, effectively transforming it into transparent gas.”

Researchers have long sought evidence to explain what happened during this period, when the universe experienced dramatic changes. After the big bang, gas in the universe was incredibly hot and dense. Over hundreds of millions of years, the gas cooled. Then, the universe hit “repeat.” The gas again became hot and ionized—and transparent.

The team’s results more concretely define the conditions at this specific “stop” in the universe’s history. “Not only does Webb clearly show that these transparent regions exist around galaxies, we’ve also measured how large they are,” explained Daichi Kashino of Nagoya University in Japan and the lead author of the team’s first paper. Think of the transparent regions of gas like hot air balloons, with galaxies the size of peas clearing that space.

Webb showed that galaxies have fully ionized the gas within a 2 million light-year radius. That’s approximately the same distance as the space between our Milky Way galaxy and our nearest neighbor, Andromeda. Over the next hundred million years, the bubbles went on to grow larger and larger, eventually merging and causing the entire universe to become transparent.

How Does Fire Behave in Microgravity? | International Space Station

How Does Fire Behave in Microgravity? | International Space Station

Fire can be a catastrophic hazard for crewed spacecraft. NASA is developing effective fire suppression techniques critical to ensuring crew safety on future missions. The Solid Fuel Ignition and Extinction (SoFIE) Growth and Extinction Limits (GEL) experiment shows a flame appearing to spin itself into extinction within the microgravity environment of the International Space Station (ISS). Scientists speculate that the flame appears to spin because that is the most effective way for it to consume oxygen. When the flow speed and oxygen concentration get too low, there is not enough oxygen to consume all the available fuel. As a result, a flame can only exist over a portion of the hot fuel causing the flame to appear to chase itself, or spin, around the fuel.

Earth Satellites: The International Space Station & The Moon

Earth Satellites: The International Space Station & The Moon

What’s that near the Moon? It is the International Space Station (ISS). Although the ISS may appear to be physically near the Moon, it is not—it is physically closer to the Earth. In low Earth orbit and circulating around our big blue marble about every 90 minutes, the ISS was captured photographically as it crossed nearly in front of the Moon. The Moon, itself in a month-long orbit around the Earth, shows a crescent phase as only a curving sliver of its Sun-illuminated half is visible from the Earth. The featured image was taken in late March 2023 from Shanghai, China and shows not only details of Earth's largest human-made satellite, but details of the cratered and barren surface of Earth's largest natural satellite. Over the next few years, humanity is planning to send more people and machines to the Moon than ever before.

A Dishevelled Irregular Galaxy in Pegasus: NGC 7292 | Hubble

A Dishevelled Irregular Galaxy in Pegasus: NGC 7292 | Hubble


The galaxy NGC 7292 billows across this image from the NASA/European Space Agency  Hubble Space Telescope, accompanied by a handful of bright stars and the indistinct smudges of extremely distant galaxies in the background. It lies around 44 million light-years from Earth in the constellation Pegasus.

This slightly dishevelled galaxy is irregular, meaning that it lacks the distinct spiral arms of galaxies like the Whirlpool Galaxy or the smooth elliptical shape of galaxies like Messier 59. Unusually, its core is stretched out into a distinct bar, a feature seen in many spiral galaxies. Alongside its hazy shape, NGC 7292 is remarkably faint. As a result, astronomers classify NGC 7292 as a low surface brightness galaxy, barely distinguishable against the backdrop of the night sky. Such galaxies are typically dominated by gas and dark matter rather than stars.

Image Description: A galaxy fills up most of the frame from the right. It is fuzzy and diffuse, but made up of numerous tiny stars. In the core, the stars merge into a glowing bar shape. The gas and stars in the galaxy vary between warm and cool colors. They are spread over a large area, the colors mixing like clouds. The glow of the galaxy fades into a black background, with a few stars and small, distant galaxies.

Astronomers directed Hubble to inspect NGC 7292 during an observational campaign studying the aftermath of Type II supernovae. These colossal explosions happen when a massive star collapses and then violently rebounds in a catastrophic explosion that tears the star apart. Astronomers hope to learn more about the diversity of Type II supernovae they have observed by scrutinising the aftermath and remaining nearby stars of a large sample of historical Type II supernovae.

NGC 7292’s supernova was observed in 1964 and accordingly given the identifier SN 1964H. Studying the stellar neighbourhood of SN 1964H helps astronomers estimate the initial mass of the star that went supernova, and could uncover surviving stellar companions that once shared a system with the star that would become SN 1964H.

The Clown-faced Nebula: NGC 2392 | Hubble Space Telescope

The Clown-faced Nebula: NGC 2392 | Hubble Space Telescope

The Clown-faced Nebula (NGC 2392) or Caldwell 39, is a bipolar double-shell planetary nebula (PN). It was discovered by astronomer William Herschel in 1787. It is surrounded by gas that composed the outer layers of a Sun-like star. The visible inner filaments are ejected by a strong wind of particles from the central star. The outer disk contains unusual, light-year-long filaments.

NGC 2392 lies about 6,500 light-years away, and is visible with a small telescope in the constellation of Gemini.

At the center of NGC 2392, there is an O-type star with a spectral type of O(H)6f.

Some of the most breathtaking views of Earth taken from space are those that capture our planet’s limb. When viewed from the side, the Earth looks like a flat circle, and the atmosphere appears like a halo around it. This edge of the atmosphere is known as the limb.

Apollo 12 (November 14–24, 1969) was the sixth crewed flight in the United States Apollo program and the second to land on the Moon. It was launched on November 14, 1969, by NASA from the Kennedy Space Center, Florida. Commander Charles "Pete" Conrad and Lunar Module Pilot Alan L. Bean performed just over one day and seven hours of lunar surface activity while Command Module Pilot Richard F. Gordon remained in lunar orbit.
