Hubble Sees Magnetic Monster in Erupting Galaxy

Hubble Sees Magnetic Monster in Erupting Galaxy

Hubblecast 18: The Hubble Space Telescope has solved a long-standing puzzle by resolving giant but delicate filaments shaped by a strong magnetic field around the active galaxy NGC 1275. It is the most striking example so far of the influence of the immense tentacles of extragalactic magnetic fields.

A Delicate Extragalactic Web: Galaxy NGC 1275 | Hubble

The dusty web of filaments seen in this fulldome clip have been teased out of their host galaxy NGC 1275 by rising "bubbles" of plasma produced by the galaxy's central black hole. Their delicate forms should have collapsed long ago, but are thought to be preserved by a weak magnetic field around them.

The red filaments seen near the center are fine threads of gas up to 20,000 light-years long, but only 200 light-years wide. They are sustained by magnetic fields, with the thinner threads requiring more support.

Magnetic Monster: Galaxy NGC 1275 | Hubble

Magnetic Monster: Galaxy NGC 1275 | Hubble

This stunning image of NGC 1275 was taken using the NASA/European Space Agency Hubble Space Telescope's Advanced Camera for Surveys in July and August 2006. It provides amazing detail and resolution of the fragile filamentary structures, which show up as a reddish lacy structure surrounding the central bright galaxy NGC 1275. These filaments are cool despite being surrounded by gas that is around 55 million degrees Celsius hot. They are suspended in a magnetic field which maintains their structure and demonstrates how energy from the central black hole is transferred to the surrounding gas.

Distance: 250 million light years

By observing the filamentary structure, astronomers were, for the first time, able to estimate the magnetic field's strength. Using this information they demonstrated how the extragalactic magnetic fields have maintained the structure of the filaments against collapse caused by either gravitational forces or the violence of the surrounding cluster during their 100-million-year lifetime.

This is the first time astronomers have been able to differentiate the individual threads making up such filaments to this degree. Astonishingly, they distinguished threads a mere 200 light-years across. By contrast, the filaments seen here can be a gaping 200,000 light-years long. The entire image is approximately 260,000 light-years across.

Also seen in the image are impressive lanes of dust from a separate spiral galaxy. It lies partly in front of the giant elliptical central cluster galaxy and has been completed disrupted by the tidal gravitational forces within the galaxy cluster. Several striking filaments of blue newborn stars are seen crossing the image.

Variable Nebula: NGC 2261 | Hubble

Variable Nebula: NGC 2261 | Hubble

Hubble's variable nebula is named (like the Hubble telescope itself) after the American astronomer Edwin P. Hubble, who carried out some of the early studies of this object. It is a fan-shaped cloud of gas and dust which is illuminated by R Monocerotis (R Mon), the bright star at the bottom end of the nebula. Dense condensations of dust near the star cast shadows out into the nebula, and as they move the illumination changes, giving rise to the variations first noted by Hubble.

The star itself, lying about 2,500 light-years from Earth, cannot be seen directly, but only through light scattered off of dust particles in the surrounding nebula. R Mon is believed to have a mass of about 10 times that of the Sun, and to have an age of only 300,000 years. There is probably a symmetrical counterpart of the fan-shaped nebula on the southern side of the star, but it is heavily obscured from view by dust lying between this lobe and our line of sight.

Distance: 2,500 light years

The Hubble Heritage team made this image from observations of R Mon acquired by William Sparks (STScI), Sylvia Baggett (STScI) and collaborators.

Observations from the Juno spacecraft’s passes of Juputer's moon Europa have provided new views of this ocean world, resulting in remarkable imagery and unique science. Jupiter’s moon Europa has an icy crust covering a vast, global ocean.

NASA’s Jet Propulsion Laboratory, a division of Caltech in Pasadena, California, manages the Juno mission for the principal investigator, Scott J. Bolton, of the Southwest Research Institute in San Antonio. Juno is part of NASA’s New Frontiers Program, which is managed at NASA’s Marshall Space Flight Center in Huntsville, Alabama, for the agency’s Science Mission Directorate in Washington. Lockheed Martin Space in Denver built and operates the spacecraft.
