Space Oddities: The Galactic Triplet Arp 248 | Hubble

Space Oddities: The Galactic Triplet Arp 248 | Hubble

This image from the NASA/European Space Agency Hubble Space Telescope shows two of the galaxies in the galactic triplet Arp 248—also known as Wild's Triplet—which lies around 200 million light-years from Earth in the constellation Virgo. The two large spiral galaxies visible in this image—which flank a smaller, unrelated background spiral galaxy—seem to be connected by a luminous bridge. This elongated stream of stars and interstellar dust is known as a tidal tail, and it was formed by the mutual gravitational attraction of the two foreground galaxies.

Image description: Two spiral galaxies are viewed almost face-on; they are a mix of pale blue and yellow in color, crossed by strands of dark red dust. They lie in the upper-left and lower-right corners. A long, faint streak of pale blue joins them, extending from an arm of one galaxy and crossing the field diagonally. A small spiral galaxy, orange in color, is visible edge-on, left of the lower galaxy.

This observation comes from a project which delves into two rogues’ galleries of weird and wonderful galaxies: A Catalogue Of Southern Peculiar Galaxies And Associations, compiled by astronomers Halton Arp and Barry Madore, and the Atlas of Peculiar Galaxies, compiled by Halton Arp. Each collection contains a menagerie of spectacularly peculiar galaxies, including interacting galaxies such as Arp 248, as well as one- or three-armed spiral galaxies, galaxies with shell-like structures, and a variety of other space oddities.

Hubble used its Advanced Camera for Surveys to scour this menagerie of eccentric galaxies in search of promising candidates for future observations with the NASA/European Space Agency/Canadian Space Agency James Webb Space Telescope, the Atacama Large Millimeter/submillimeter Array, and Hubble itself. With such a wealth of astronomical objects to study in the night sky, projects such as this, which guide future observations, are a valuable investment of observing time. As well as the scientific merits of observing these weird and wonderful galaxies, they were also—very unusually—selected as Hubble targets because of their visual appeal to the general public!

Zoom on Dusty Reflection Nebula: NGC 7023 | Hubble

Zooming in on NGC 7023, or the Iris Nebula, a reflection nebula located in the constellation of Cepheus, the King. With bright light from the nearby HD 200775 illuminating it from above, the dust in the nebula resembles thick mounds of billowing cotton. It is actually made up of tiny particles of solid matter. Both background and foreground stars are dotted throughout the image.

Researchers studying the object are particularly interested in the region to the left and slightly above center in the image, where dusty filaments appear redder than is expected.

A Blushing Dusty Nebula: NGC 7023 | Hubble

This close-up of an area in the northwest region of the large Iris Nebula seems to be clogged with cosmic dust. With bright light from the nearby star HD 200775 illuminating it from above, the dust resembles thick mounds of billowing cotton. It is actually made up of tiny particles of solid matter, with sizes from ten to a hundred times smaller than those of the dust grains we find at home. Both background and foreground stars are dotted throughout the image. Researchers studying the object are particularly interested in the region to the left and slightly above center in the image, where dusty filaments appear redder than is expected.

Distance: 1,400 light years

North is down, East is right. The field of view is 3.3 arcminutes. The image is a composite of four images obtained through blue, green, near-infrared and H-alpha filters.

Zoom in on Elliptical Galaxy ESO 306-17 | Hubble

Zoom in on Elliptical Galaxy ESO 306-17 | Hubble

When zooming in closely on ESO 306-17, one can see faint clusters of stars through the bright shine of the galaxy's large halo. These are globular clusters—tightly bound groups of stars that can often fend off cannibalism from larger, "bully" galaxies. Studying these surrounding clusters will prove helpful to astronomers in their pursuit to put the pieces of ESO 306-17's history together.

Large & Bright Elliptical Galaxy ESO 306-17 in Columba | Hubble

Large & Bright Elliptical Galaxy ESO 306-17 in Columba | Hubble

This image from the Advanced Camera for Surveys aboard the NASA/European Space Agency Hubble Space Telescope highlights the large and bright elliptical galaxy called ESO 306-17 in the southern sky.

Distance: 500 million light years

In this image, it appears that ESO 306-17 is surrounded by other galaxies but the bright galaxies at bottom left are thought to be in the foreground, not at the same distance in the sky. In reality, ESO 306-17 lies fairly abandoned in an enormous sea of dark matter and hot gas.

Researchers are also using this image to search for nearby ultra-compact dwarf galaxies. Ultra-compact dwarfs are mini versions of dwarf galaxies that have been left with only their core due to interaction with larger, more powerful galaxies. Most ultra-compact dwarfs discovered to date are located near giant elliptical galaxies in large clusters of galaxies, so it will be interesting to see if researchers find similar objects in fossil groups.

Jupiter - Juno PJ14-19

Jupiter has a long history of surprising scientists—all the way back to 1610 when Galileo Galilei found the first moons beyond Earth. That discovery changed the way we see the universe. Fifth in line from the Sun, Jupiter is, by far, the largest planet in the solar system—more than twice as massive as all the other planets combined.

Jupiter's familiar stripes and swirls are actually cold, windy clouds of ammonia and water, floating in an atmosphere of hydrogen and helium. Jupiter’s iconic Great Red Spot is a giant storm bigger than Earth that has raged for hundreds of years.

Juno Mission Profile

Launched: Aug. 5, 2011

Arrival at Jupiter: July 4, 2016

Goal: Understand origin and evolution of Jupiter, look for solid planetary core, map magnetic field, measure water and ammonia in deep atmosphere, observe auroras.

Learn more about the Juno mission at: www.nasa.gov/juno

The Jet Propulsion Laboratory (JPL) manages the Juno mission for NASA. The mission's principal investigator is Scott Bolton of the Southwest Research Institute in San Antonio. The mission is part of NASA's New Frontiers Program, managed at the agency's Marshall Space Flight Center in Huntsville, Alabama, for NASA's Science Mission Directorate. Lockheed Martin Space Systems in Denver built the spacecraft.
