Spiral Galaxy NGC 3430: "An Island Universe" | Hubble Space Telescope

In this Hubble picture, we are treated to a detailed view of NGC 3430. A spiral galaxy, it lies 100 million light-years from Earth in the constellation Leo Minor. Several other galaxies are located relatively nearby, just out of frame; one is close enough that gravitational interaction is driving star formation in NGC 3430.

NGC 3430 is a fine example of a galactic spiral. This may be why it ended up as part of the sample that Edwin Hubble used to define his classification of galaxies. Namesake of the Hubble Space Telescope, in 1926 he authored a paper that classified four hundred galaxies by their appearance—as either spiral, barred spiral, lenticular, elliptical or irregular. This straightforward typology proved immensely influential, and the modern, more detailed schemes that astronomers use today are still based on it. NGC 3430 itself is an SAc galaxy, a spiral lacking a central bar with open, clearly-defined arms.

At the time of Hubble’s paper, the study of galaxies in their own right was in its infancy. With the benefit of Henrietta Leavitt’s work on Cepheid variable stars, Hubble had only a couple of years before settled the debate about whether these ‘nebulae’, as they were called then, were situated within our galaxy or were distant and independent. He himself referred to ‘extragalactic nebulae’ in his paper, indicating that they lay beyond the Milky Way galaxy. Once it became clear that these distant objects were very different from actual nebulae, the favored term for a while was the quite poetic ‘island universe’. While NGC 3430 may look as if it still deserves this moniker, today we simply call it and the objects like it a ‘galaxy’.

Image Description: A spiral galaxy with three prominent arms wrapping around it, and plenty of extra gas and dark dust between the arms. There are shining blue points throughout the arms and patches of gas out beyond the galaxy’s edge, where stars are forming. The center of the galaxy also shines brightly. It is on a dark background where small orange dots mark distant galaxies.

Pan of Dwarf Irregular Galaxy NGC 5238 in Canes Venatici | Hubble

Pan of Dwarf Irregular Galaxy NGC 5238 in Canes Venatici | Hubble

The galaxy featured in this Hubble picture is the dwarf irregular galaxy NGC 5238, located 14.5 million light-years from Earth in the constellation Canes Venatici. Its unexciting, blob-like appearance, resembling more an oversized star cluster than a galaxy, belies a complicated structure that has been the subject of considerable research. Here, the NASA/European Space Agency Hubble Space Telescope is able to pick out the galaxy’s countless stars, as well as its associated globular clusters—the glowing spots both inside and around the galaxy that contain ever more stars.

NGC 5238 is theorized to have recently—here meaning no more than a billion years ago—had a close encounter with another galaxy. The evidence for this is the tidal distortions of NGC 5238’s shape, the kind produced by two galaxies pulling on each other as they interact. There is no nearby galaxy that could have caused this disturbance, so the hypothesis is that the culprit is a smaller satellite galaxy that was devoured by NGC 5238. Traces of the erstwhile galaxy might be found by closely examining the population of stars in NGC 5238, a task for which the Hubble Space Telescope is an astronomer’s best tool. Two tell-tale signs would be groups of stars with properties that look out of place compared to most of the galaxy’s other stars, indicating that they were originally formed in a separate galaxy, or stars that look to have all formed abruptly at around the same time. This would occur during a galactic merger. The data used to make this image will be put to use in testing these predictions.

Despite their small size and unremarkable appearance, it is not unusual for dwarf galaxies like NGC 5238 to drive our understanding of galaxy formation and evolution. One main theory of galaxy evolution is that galaxies formed ‘bottom-up’ in a hierarchical fashion: star clusters and small galaxies were the first to form out of gas and dark matter, and they gradually were assembled by gravity into galaxy clusters and superclusters, explaining the shape of the very largest structures in the Universe today. A dwarf irregular galaxy like NGC 5238 merging with an even smaller companion is just the type of event that might have begun this process of galaxy assembly in the early Universe. So, it turns out that this tiny galaxy may serve as a testbed for the most fundamental predictions in astrophysics!

Image Description: A dwarf irregular galaxy. It appears as a cloud of bluish gas, filled with point-like stars that also spread beyond the edge of the gas. A few glowing red clouds sit near its center. Many other objects can be seen around it: distant galaxies in the background, four-pointed stars in the foreground, and star clusters that are part of the galaxy—shining spots surrounded by more tiny stars.

China's Lunar Exploration Program Welcomes More Global Partners

China's Lunar Exploration Program Welcomes More Global Partners

The United Nations has marked July 20 as International Moon Day to honor the anniversary of the first landing of a human on the Moon. Following China's successful Chang'e-6 lunar mission this year, many countries now seek to work more closely with China on future lunar programs. 

China's aerospace and lunar exploration programs are open to the world and welcome all countries to engage in cooperative missions and projects, said Wu Weiren, chief designer of the country's lunar exploration program, ahead of the International Moon Day on July 20.

After the successful operation of payloads from the European Space Agency (ESA), France, Italy, and Pakistan in China's Chang'e-6 Moon mission, China will aim to expand its international collaboration in upcoming lunar exploration endeavors, Wu said in an interview with China Global Television Network (CGTN).

"We are open and welcome international cooperation from all countries, including those countries from the Global South, emerging BRICS countries, as well as Western countries. We do not have any isolating or exclusionary policies, and we want to cooperate in an all-round way. I think our principle is to share data, share results. We are willing to co-build and co-share with our partners. We have no intention to establish small circles or groups. Therefore, China's aerospace and lunar exploration programs, including planetary exploration, are all open to the whole world," said Wu.

He also offered an update on the development of the international lunar research station (ILRS) and the country’s plans for the station.

"The international lunar research station is actually the first large-scale scientific project to be implemented in our country. We are preparing to build a lunar scientific research station at the south pole of the Moon. This scientific research station will be combined with an orbital station and a lunar surface station, plus ground facilities such as the headquarters for major scientific projects. This is being done so that work can continue for a long time, with or without people at the south pole of the moon. It will enable scientific exploration and resource development," said Wu.

"We hope to build a basic station by 2035, and an extended station by 2045. So far, we have signed agreements with more than 10 countries and nearly 30 international research institutions. We hope to work with 50 countries by inviting 500 foreign scientific research institutions, and 5,000 foreign scientific research personnel to jointly build our international lunar scientific research station," he added.

Wu said that in the future, visiting the the international lunar research station will no longer be just a dream for ordinary citizens, while Chinese astronauts and international partners will reach deeper into the solar system.

"I think China should also think about these plans, including space tourism, space breeding, and space mining in the future. We can achieve these targets on the Moon and Mars. I don't think this is too far away," Wu said.

Space breeding involves exposing plant seeds to cosmic radiation and microgravity in space to generate potentially beneficial genetic mutations.

30 Years Since Historic Shoemaker-Levy 9 Comet Impacts of Jupiter | NASA

30 Years Since Historic Shoemaker-Levy 9 Comet Impacts of Jupiter | NASA

In July 1994, astronomers around the world watched with bated breath as fragments of comet Shoemaker-Levy 9 slammed into the planet Jupiter.

The impacts proved to be impressive. Fragments plunged into Jupiter’s atmosphere over the course of six days. Like the splash from throwing a rock into a pond, the impacts created giant plumes of material from Jupiter’s lower atmosphere which rose as high as 1,900 miles or 3,000 kilometers above the cloud tops into the stratosphere. In the aftermath, the plume splashback scarred Jupiter’s atmosphere with dark clouds of impact debris that could be seen for months as they were gradually dispersed by Jupiter's winds.

This historic event helped to give rise to the field of planetary defense.

The Plaque NASA Apollo 11 Astronauts Left on The Moon in July 1969

The Plaque NASA Apollo 11 Astronauts Left on The Moon in July 1969

This is a replica of the plaque the Apollo 11 astronauts left behind on the Moon in commemoration of the historic event. The plaque was made of stainless steel, measuring nine by seven and five-eighths inches, and one-sixteenth inch thick. The plaque was attached to the ladder on the landing gear strut on the descent stage of the Apollo 11 lunar module (LM). Covering the plaque during the flight, there was a thin sheet of stainless steel that was removed on the lunar surface.

On July 20, 1969—55 years ago today—NASA's Apollo 11 lunar module, named "Eagle", touched down on the Moon with commander Neil Armstrong and lunar module pilot Buzz Aldrin. They landed in the south-western corner of the dark lunar plain Mare Tranquillitatis ("Sea of Tranquility") on the Moon's near side.

The Apollo 11 crew left behind an American flag, a patch honoring the fallen Apollo 1 crew, and this plaque on one of Eagle’s legs. It reads, “Here men from the planet Earth first set foot upon the moon. July 1969 A.D. We came in peace for all mankind.”

NASA Apollo 11 Mission Emblem: An Eagle as a Dove of Peace | 55th Anniversary

NASA Apollo 11 Mission Emblem: An Eagle as a Dove of Peace | 55th Anniversary

"The Eagle has landed."

On July 20, 1969—55 years ago today—NASA's Apollo 11 lunar module, named "Eagle", touched down on the Moon with commander Neil Armstrong and lunar module pilot Buzz Aldrin. They landed in the south-western corner of the dark lunar plain Mare Tranquillitatis ("Sea of Tranquility") on the Moon's near side.

The Apollo 11 crew left behind an American flag, a patch honoring the fallen Apollo 1 crew, and a plaque on one of Eagle’s legs. It reads, “Here men from the planet Earth first set foot upon the moon. July 1969 A.D. We came in peace for all mankind.”

Michael Collins, the Command and Service Module pilot, designed the mission emblem for Apollo 11. It is the only mission emblem where the names of the astronauts are not written at the edge, as was common practice on the Mercury and Gemini flights and the first three Apollo flights, as well as on subsequent missions. 

Collins wanted to show that the crew was flying to the Moon on behalf of all the 400,000 people who were involved in the construction of the launcher and the three spacecraft modules, the preparations and the planning. The bald eagle, the heraldic creature of the USA, holds an olive branch in its talons. This expresses the peaceful character of the mission. 

The Earth, the place where the Apollo 11 crew came from and would return safely to in order to fulfill United States President John F. Kennedy’s challenge to the nation, rested on a field of black, representing the vast unknown of space.

Note: It has since been noticed that the Earth above the lunar horizon here is illuminated by the Sun from the wrong direction during Apollo 11’s flight along the lunar equator. The hemisphere in shadow should be on the underside and not to the left as the emblem depicted.

Small Sagittarius Star Cloud: Messier 24

Small Sagittarius Star Cloud: Messier 24

Unlike most entries in Charles Messier's famous catalog of deep sky objects, M24 is not a bright galaxy, star cluster, or nebula. It is a gap in nearby, obscuring interstellar dust clouds that allows a view of the distant stars in the Sagittarius spiral arm of our Milky Way galaxy. 

Direct your gaze through this gap with binoculars or small telescope and you are looking through a window over 300 light-years wide at stars 10,000 light-years or more from Earth. Also called the Small Sagittarius Star Cloud, M24's luminous stars are left of center in this vast starscape. Covering over 6 degrees or the width of 12 full moons in the constellation Sagittarius, the telescopic field of view includes dark markings B92 and B93 near the center of M24, along with other clouds of dust and glowing nebulae toward the center of the Milky Way.

Galaxy Cluster Abell 2390 | Europe's Euclid & XMM-Newton Space Telescopes

Galaxy Cluster Abell 2390 | Europe's Euclid & XMM-Newton Space Telescopes

Scientists have combined Euclid’s recently released image of the massive galaxy cluster Abell 2390 with the European Space Agency's XMM-Newton’s X-ray observation of the same site to showcase the blazing million degree hot gas that fills the space between the galaxies.

Abell 2390 is a giant conglomeration of many galaxies like the Milky Way, located 2.7 billion light-years from Earth. Euclid’s image was obtained from observations in visible and near-infrared light and features more than 50,000 galaxies. Thousands of these are part of the cluster. Yet, we cannot directly see most of the mass that makes up this cluster in Euclid’s sparkling view.

A galaxy cluster like Abell 2390 is a gigantic pile of dark matter that makes up about 80% of its total mass. Most of the ‘normal’ matter in the pile is in the form of scorching hot gas. It makes up about 15% of the cluster. These galaxies, add up to only a few percent of the total mass, sit in this pile like raisins in a cake.

The temperature of the gas ranges between 10 to 100 million degrees Celsius. Here, electrons are stripped from the atoms in the gas and become ionized. The sizzling mixture of charged particles produces the X-rays captured by XMM-Newton.

In the image, the X-ray light appears as a blue glow that permeates the expanses between the galaxies. The diffuse light is brighter towards the center of the cluster, indicating that there the gas becomes hotter and more concentrated.

By mapping where the hot gas is located and studying how it behaves, astronomers learn more about how galaxy clusters grow, and about how galaxies interact and evolve in this dynamic environment.

The gigantic, curved arcs in Euclid’s image are the result of gravitational lensing where the light travelling to us from more distant galaxies is bent and distorted by the matter in the foreground (‘normal’ and dark matter). Euclid uses lensing as a key technique for exploring the dark Universe, indirectly mapping the amount and distribution of dark matter both in galaxy clusters and elsewhere.

Severe Thunderstorms Race Through American Midwest | NOAA

Severe Thunderstorms Race Through American Midwest | NOAA

Parts of the Midwest are cleaning up after thunderstorms barreled through the region on the night of Monday, July 15, 2024, bringing hurricane-force winds and multiple tornadoes around Chicago. More than 600 reports of damaging winds from Iowa to Michigan left over 350,000 customers without power Tuesday morning.

The storm complex was a derecho, or a widespread, long-lived wind storm that is associated with a band of fast-moving showers or thunderstorms. Storms first erupted during the mid-evening hours in central and eastern Iowa, bringing tennis-ball-size hail in Crawford. Initial storms began as rotating supercells, including one that spawned a tornado near Des Moines, then continued through northeastern Indiana along a 500-mile-long path before dissipating around 2 a.m. Tuesday. It toppled hundreds of trees, downed wires and power poles, ripped off roofs and damaged vehicles.

In Chicago, forecasters at the National Weather Service had to abandon their posts as a tornado approached, transferring warnings to a sister office in Gaylord, Michigan. These storms then merged into a cluster, reaching 55,000 feet in height. From there, the storms moved east along a stalled frontal boundary. Cooler air was present to the north, with very warm, moist air to the south. Storms tend to straddle boundaries, in this case, steering them into northern and central Illinois and then Chicago.
