Zooming to Black Hole at Milky Way Galaxy's Core: Sagittarius A* | ESO

Zooming to Black Hole at Milky Way Galaxy's Core: Sagittarius A* | ESO

The European Southern Observatory’s exquisitely sensitive GRAVITY instrument has added further evidence to the long-standing assumption that a supermassive black hole lurks in the center of the Milky Way. New observations show clumps of gas swirling around at about 30% of the speed of light on a circular orbit just outside a four million solar mass black hole—the first time material has been observed orbiting close to the point of no return, and the most detailed observations yet of material orbiting this close to a black hole.

This video starts with a wide view of the Milky Way and then zooms into a visualization of data from simulations of orbital motions of gas swirling around at about 30% of the speed of light on a circular orbit around the supermassive black hole Sagittarius A*.

The Center of Our Milky Way Galaxy | Hubble

The Center of Our Milky Way Galaxy | Hubble

Infrared image of Milky Way's galactic core

This annotated, infrared image from the Hubble Space Telescope shows the scale of the galactic core. The galaxy's nucleus (marked) is home to a central, supermassive black hole called Sagittarius A-star.

Peering deep into the dusty heart of our Milky Way galaxy using infrared, NASA’s Hubble Space Telescope reveals a rich tapestry of more than half a million stars. Except for a few blue foreground stars, the stars are part of the Milky Way’s nuclear star cluster, the most massive and densest star cluster in our galaxy. So packed with stars, it is equivalent to having a million suns crammed between us and our closest stellar neighbor, Alpha Centauri. At the very hub of our galaxy, this star cluster surrounds the Milky Way’s central supermassive black hole—about 4 million times the mass of our sun.

This picture, spanning 50 light-years across, is a mosaic stitched from nine separate images from Hubble’s Wide Field Camera 3. The center of the Milky Way is located 27,000 light-years away. The “snowstorm” of stars in the image is just the tip of the iceberg: Astronomers estimate that about 10 million stars in this cluster are too faint to be captured in this image.

In this image, scientists translated the infrared light, invisible to human eyes, into colors our eyes can see. The red stars are either embedded or shrouded by intervening dust. Extremely dense clouds of gas and dust are seen in silhouette, appearing dark against the bright background stars. These clouds are so thick that even Hubble’s infrared capability could not penetrate them.

Hubble’s sharp vision allowed astronomers to measure the movements of the stars here over four years. Using this information, scientists were able to infer important properties such as the mass and structure of the nuclear star cluster. The motion of the stars may also offer a glimpse into how the star cluster was formed—whether it was built up over time by globular star clusters that happen to fall into the galaxy’s center, or from gas spiraling in from the Milky Way’s disk to form stars at the core.

The Hubble Space Telescope is a project of international cooperation between NASA and the European Space Agency. NASA's Goddard Space Flight Center in Greenbelt, Maryland, manages the telescope. The Space Telescope Science Institute (STScI) in Baltimore, Maryland, conducts Hubble science operations. STScI is operated for NASA by the Association of Universities for Research in Astronomy in Washington, D.C.

The Fireworks Galaxy NGC 6946: 25 million light years away | Hubble

The Fireworks Galaxy NGC 6946: 25 million light years away | Hubble


In the last century alone, galaxy NGC 6946 has experienced 10 observed supernovae, earning its nickname as the Fireworks Galaxy. In comparison, our Milky Way averages just 1-2 supernova events per century. This NASA/European Space Agency Hubble Space Telescope image shows the stars, spiral arms, and stellar environments of NGC 6946 in phenomenal detail. 

We are able to marvel at NGC 6946 as it is a face-on galaxy. It means that we see the galaxy “facing” us, rather than seeing it from the side (known as edge-on). The Fireworks Galaxy is further classified as an intermediate spiral galaxy and as a starburst galaxy. The former means the structure of NGC 6946 sits between a full spiral and a barred spiral galaxy, with only a slight bar in its center, and the latter means it has an exceptionally high rate of star formation.

The galaxy resides 25.2 million light-years away, along the border of the northern constellations of Cepheus and Cygnus (The Swan).

Pan of Spiral Galaxy NGC 3430 in Leo Minor | Hubble Space Telescope

Pan of Spiral Galaxy NGC 3430 in Leo Minor | 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.

Nebula Kohoutek 3-46: A ‘Butterfly’ from Death’s Door | Gemini North Telescope

Nebula Kohoutek 3-46: A ‘Butterfly’ from Death’s Door | Gemini North Telescope


This ghostly, butterfly-shaped planetary nebula, captured by the Gemini North telescope, one half of the International Gemini Observatory, supported in part by the U.S. National Science Foundation and operated by NOIRLab, is known as Kohoutek 3-46. Kohoutek 3-46 derives its name from the prolific planetary nebula hunter that discovered it, Czech astronomer Luboš Kohoutek. 

Located in the constellation Cygnus, Kohoutek 3-46 is estimated to be around 20,000 years old and around 7,200 light-years away. The term ‘planetary nebula’ is a misnomer, since these nebulae are unrelated to planets. The term originates from their planet-like round shape. Kohoutek 3-46 has expanded into an unusual bipolar shape, classified by its well-defined hourglass shape, prominent equatorial ring and marked waist. About 10–20% of planetary nebulae are bipolar. No matter the shape they take on, these glowing clouds of gas form after a star of one to eight times the mass of the Sun has expanded into a red giant. As the core of the red giant contracts, the star expels layers of its atmosphere into space. Energetic ultraviolet radiation from the hot, exposed core then ionizes this gaseous shell around it, ‘illuminating’ the planetary nebula.

Since 2002, Gemini North has also been known as the Frederick C. Gillett Gemini North telescope. Dr. Gillett, who died in April 2001, was one of the primary visionaries of the Gemini telescopes. He was instrumental in assuring that the design of Gemini's twin 8-meter telescopes would make major scientific contributions to astronomy.
