Zooming in on The Running Chicken Nebula & Thackeray's Globules | ESO
This zoom runs from a very wide view of the Milky Way all the way into a very close-up view of the spectacular stellar nursery IC 2944, also known as the Running Chicken Nebula. This image from the Very Large Telescope (VLT) also shows a group of thick clouds of dust known as the Thackeray globules, silhouetted against the pale pink glowing gas of the nebula. These globules are under fierce bombardment from the ultraviolet radiation from nearby hot young stars. They are both being eroded away and also fragmenting, rather like lumps of butter dropped onto a hot frying pan. It is likely that Thackeray's globules will be destroyed before they can collapse and form new stars.
Distance: 6,500 light years

IC 2944, also known as the Running Chicken Nebula, the Lambda Centauri Nebula or the λ Centauri Nebula, is an open cluster with an associated emission nebula found in the constellation Centaurus, near the star λ Centauri. This image also shows a group of thick clouds of dust known as the Thackeray globules silhouetted against the pale pink glowing gas of the nebula. These globules are under fierce bombardment from the ultraviolet radiation from nearby hot young stars. They are both being eroded away and also fragmenting, rather like lumps of butter dropped onto a hot frying pan. It is likely that Thackeray’s globules will be destroyed before they can collapse and form new stars.

This intriguing view of a spectacular stellar nursery IC 2944 was originally released to celebrate the 15th anniversary of the European Southern Observatory's Very Large Telescope (VLT) in 2013.
A Black Hole Stellar Delivery Service Found in Galaxy NGC 4424 | NASA Chandra
One galaxy is acting as a black hole delivery service for another galaxy.
NASA’s Chandra X-ray Observatory found clues in data from NGC 4424.
This spiral galaxy is located about 54 million light-years from Earth.
Astronomers use such results to better understand how galaxies and black holes grow.
Astronomers may have witnessed a galaxy’s black hole delivery system in action. A new study using data from NASA’s Chandra X-ray Observatory and Hubble Space Telescope outlines how a large black hole may have been delivered to the spiral galaxy NGC 4424 by another, smaller galaxy.
NGC 4424 is located about 54 million light-years from Earth in the Virgo galaxy cluster. The main panel shows a wide-field view, about 45,000 light-years wide, of this galaxy in optical light from Hubble. The center of this galaxy is expected to host a large black hole estimated to contain a mass between 60,000 and 100,000 Suns.
Astronomers examining data from NASA’s Chandra X-ray Observatory found an elongated object, which they determined is a cluster of stars. They refer to this object as “Nikhuli,” a name relating to the Tulini festive period of celebrating and wishing for a rich harvest. This name is taken from the Sumi language from the Indian state of Nagaland. The Chandra data shows a point source of X-rays.
The researchers determined Nikhuli is likely the center of a small galaxy that has had most of its stars stripped away as it collides with the larger galaxy NGC 4424. Nikhuli has also been stretched out by gravitational forces as it falls towards the center of NGC 4424, giving it an elongated shape. Currently, Nikhuli is about 1,300 light-years from the center of NGC 4424, or about 20 times closer than the Earth is to the Milky Way’s giant black hole.
After considering other possibilities, the researchers determined that these results imply that Nikhuli is likely acting as a delivery system for NGC 4424’s supply of black holes, in this case bringing along a massive one. If the center of NGC 4424 contains a massive black hole, Nikhuli’s massive black hole should end up orbiting it. The separation of the pair should then shrink until gravitational waves are produced and the two massive black holes merge with each other.
Spiral Galaxy NGC 4424 and its Modern Counterpart | Hubble
Some astronomical objects have endearing or quirky nicknames, inspired by mythology or their own appearance. Take, for example, the constellation of Orion (The Hunter), the Sombrero Galaxy, the Horsehead Nebula, or even the Milky Way. However, the vast majority of cosmic objects appear in astronomical catalogs, and are given rather less poetic names based on the order of their discovery.
Two galaxies are clearly visible in this Hubble image, the larger of which is NGC 4424. This galaxy is catalogued in the New General Catalog of Nebulae and lusters of Stars (NGC), which was compiled in 1888. The NGC is one of the largest astronomical catalogues, which is why so many Hubble Pictures of the Week feature NGC objects. In total there are 7840 entries in the catalog and they are also generally the larger, brighter, and more eye-catching objects in the night sky, and hence the ones more easily spotted by early stargazers.
The smaller, flatter, bright galaxy sitting just below NGC 4424 is named LEDA 213994. The Lyon-Meudon Extragalactic Database (LEDA) is far more modern than the NGC. Created in 1983 at the Lyon Observatory it contains millions of objects. However, many NGC objects still go by their initial names simply because they were christened within the NGC first. No astronomer can resist a good acronym, and “LEDA” is more appealing than “the LMED”, perhaps thanks to the old astronomical affinity with mythology when it comes to naming things: Leda was a princess in Ancient Greek mythology.
Lightning is a major public safety threat. It can strike at any time, but it is most common in the summer months. Lightning kills about 20 people each year in the United States and hundreds more are injured.
Recent severe thunderstorm activity has highlighted the dangers associated with lightning strikes. In the span of less than a week in early August, lightning led to several injuries and fatalities.

Earth Moonrise over Nile Delta & Planet Venus | International Space Station
Moonrise seen from the International Space Station taken by European Space Agency astronaut Samantha Cristoforetti of Italy from orbit during her Minerva mission. It is a sight rarely seen: Earth’s natural satellite appearing over the horizon above the always-distinctive Nile delta at night—taken from 400 km above our planet. The brighter dot in the middle is the planet Venus.
The Moon is the only place that has been seen by every human being on our planet, but only around 600 astronauts have seen the Moon from Earth orbit.

The NASA/European Space Agency Hubble Space Telescope provides a striking observation of the carbon star CW Leonis, which resembles a baleful orange eye glaring from behind a shroud of smoke.
The bright beams of light radiating outwards from CW Leonis are one of the most intriguing parts of this image, as they have changed in brightness within a 15 year period—an incredibly short span of time in astronomical terms, which is demonstrated in this timelapse. Astronomers speculate that gaps in the shroud of dust surrounding CW Leonis may allow these beams of starlight to pierce through and illuminate dust further from the star. However the exact cause of the dramatic changes in their brightness is as yet unexplained.

CW Leonis glowers from deep within a thick shroud of dust in this image. Lying roughly 400 light-years from Earth in the constellation Leo, CW Leonis is a carbon star—a luminous type of red giant star with a carbon-rich atmosphere. The dense clouds of sooty gas and dust engulfing this dying star were created as the outer layers of CW Leonis itself were thrown out into the void.

Spiral Galaxy NGC 2276: Wide-field View | Steward Observatory
This image shows a wide-field view of NGC 2276, a spiral galaxy 120 million light-years away in the constellation of Cepheus. At first glance, the delicate tracery of bright spiral arms and dark dust lanes resembles countless other spiral galaxies. A closer look reveals a strangely lopsided galaxy shaped by gravitational interaction and intense star formation.
