Hubble Captures Stunning Image of Evil Eye Galaxy Located 17 Million Light-Years from Earth

NASA / ESA’s Hubble Space Telescope captured a stunning image of the Evil Eye galaxy, also known as NGC 4826, located 17 million light-years from Earth in the constellation Coma Berenices. What stands out most is its bright yellow nucleus, which shines brightly amongst dark dust in brown and orange.

This relatively isolated spiral galaxy was first discovered by Edward Pigott in March 1779, and then independently by Johann Elert Bode in April of the same year, as well as by Charles Messier the next year. Astronomers note that the inner disk contains the prominent dust lanes of the galaxy, while the the stellar population exhibits no measurable counter-rotation.

First discovered in 1799, astronomers know this galaxy by its peculiar internal motion. The gas in the inner and outer regions move in opposite directions, which may be due to a recent galactic merger,” said NASA.

Hubble Captures Massive Galaxy Cluster Abell 3192 That Curves Spacetime Around It

NASA / ESA’s Hubble Space Telescope captured a stunning image of galaxy cluster Abell 3192, suffused with hot gas that emits powerful X-rays, curving spacetime around it. This phenomenon is called a gravitational lens, where smaller galaxies behind the cluster can be observed being distorted into long, warped arcs around its edges.

In this image, we can see a cluster of galaxies, concentrated around two large elliptical galaxies, while the black background is bathed in smaller galaxies of all shapes and sizes. In the top left and bottom right, there are a few galaxies that appear notably distorted into curves by gravity. Abell 3192 was initially thought to comprise a single cluster of galaxies, concentrated at a single distance, but the cluster’s mass seemed to be densest at two distinct points instead of just one.

It was subsequently shown that the original Abell cluster actually comprised two independent galaxy clusters — a foreground group around 2.3 billion light-years from Earth, and a further group at the greater distance of about 5.4 billion light-years from our planet,” said the ESA.

NASA’s James Webb and Hubble Space Telescopes Capture Christmas Tree Galaxy Cluster

NASA’s James Webb and Hubble space telescopes used their specialized instruments to capture an expansive, yet festive, image of galaxy cluster known as MACS0416 by combining visible as well as infrared light data. It’s been nicknamed the Christmas Tree Galaxy Cluster and located approximately 4.3 billion light-years from Earth.

By combining both Webb and Hubble space telescopes, astronomers were able to discover a multitude of galaxies outside the cluster and a sprinkling of sources that vary over time, possibly due to gravitational lensing. What do the colors mean? The bluest galaxies you see relatively nearby, while the redder ones more distant as detected by Webb.

We’re calling MACS0416 the Christmas Tree Galaxy Cluster, both because it’s so colorful and because of these flickering lights we find within it. We can see transients everywhere,” said Haojing Yan, lead author of one paper describing the scientific results.

Hubble Captures More Vivid Image of Barred Spiral Galaxy NGC 1385 Located 30 Million Light-Years Away

NASA / ESA’s Hubble Space Telescope recently captured a more vivid image of barred spiral galaxy NGC 1385 located 30 million light-years away in the constellation Fornax. Featuring several arms mixed together and an overall oval shape, while its center glows brightly.

Bright pink patches and filaments of dark red dust can also be seen spread across the center. This more recent image boasts a pinkish-red and umber shades, whereas the former image was dominated by cool blues. This chromatic variation was made in order to represent the different number and type of filters used to collect the data used to make the respective images.

It is understandable to be a bit confused as to how the same galaxy, imaged twice by the same telescope, could be represented so differently in two different images. The reason is that — like all powerful telescopes used by professional astronomers for scientific research — Hubble is equipped with a range of filters,” said the ESA.

Hubble Captures Spanish Dancer Galaxy NGC 1566 Located 60 Million Light-Years Away

Located 60 million light-years from Earth in the constellation Dorado is spiral galaxy NGC 1566, also known as the Spanish Dancer Galaxy. This Hubble image reveals that it does not have either a clearly present or a clearly absent bar-shaped structure at its galactic center.

We see the entire Spanish Dancer Galaxy centered and face-on, with two spiral arms that each make only a half-turn from start to finish, resembling the shape of a comma. On second glance, you’ll also notice lanes of dark dust that follow the arms into the center before splitting into many swirling fibers around the glowing galactic core. The bright pink regions along the arms are signs of new star formation.

The galaxy owes its nickname to the vivid and dramatic swirling lines of its spiral arms, which could evoke the shapes and colors of a dancer’s moving form,” said the ESA Hubble team.

Hubble Space Telescope Captures a Serene Ultraviolet View of Jupiter

NASA / ESA’s Hubble Space Telescope recently captured a serene view of Jupiter in ultraviolet wavelengths. The gas giant’s iconic “Great Red Spot” may appear red to human eyes, but this ultraviolet image provides a different, darker view, caused by the high altitude haze particles absorbing light at these wavelengths.

On another note, the typical reddish, wavy polar hazes are absorbing a bit less of this light due to differences in either particle size, composition, or altitude. Astronomers created this ultraviolet image using part that is part of a Hubble proposal studying Jupiter’s stealthy superstorm system. Eventually, the team plans to map deep water clouds using the Hubble data to define 3D cloud structures in Jupiter’s atmosphere.

This is a false-color image because the human eye cannot detect ultraviolet light. Therefore, colors in the visible light spectrum were assigned to the images, each taken with a different ultraviolet filter. In this case, the assigned colors for each filter are: Blue: F225W, Green: F275W, and Red: F343N,” said the NASA Hubble Mission Team.

Hubble Captures Dazzling Image of Hazy-Looking Spiral Galaxy NGC 941

Photo credit: ESA/Hubble & NASA, C. Kilpatrick
NASA / ESA’s Hubble Space Telescope captured a dazzling image of the hazy-looking spiral galaxy NGC 941 located approximately 55 million light-years from Earth. This image uses data collected by Hubble’s Advanced Camera for Surveys (ACS) to study supernova SN 2005ad, which occurred within the galaxy some years ago.

NGC 941 can be seen here in a face-on orientation from Earth, with the spiral arms of the galaxy shining bright, but somewhat hazily. These arms merge into a swirling disc with a faint halo of dimmer gas around it, while its core glows vibrantly in a lighter color. The two redder visually smaller galaxies and a bright star can also be observed around the galaxy, with more miniature cosmic objects in the background.

So many supernovae are spotted by skilful amateurs such as Itagaki that there is actually an online system set up for reporting them (the Transient Name Server). This is a big help to professional astronomers, because with supernova events time is truly of the essence,” said the ESA.
