Astronomers Find First Direct Evidence of Galaxy ‘Metamorphosis’

This Hubble image shows a bipolar planetary nebula named the Twin Jet Nebula, located about 5,560 light-years away in the constellation Ophiuchus. Bipolar planetary nebulae are formed when the central object is not a single star, but a binary system. Studies have shown that the nebula’s size increases with time, and measurements of this rate of increase suggest that the stellar outburst that formed the lobes occurred just 1,200 years ago.

Jakobshavn glacier, also known as Sermeq Kujalleq and the Jakobshavn Isbræ, is a large glacier in West Greenland and is among the world’s most dynamic glaciers. Radar images from ESA’s Sentinel-1A captured the glacier before and after a massive calving event, which took place between 14 and 16 August 2015. The image composite includes different Sentinel-1A images from 27 July, and 13 and 19 August. The red, green and blue indicate the position of the calving front and other dynamic features on each respective date. Image credit: Copernicus Sentinel data /ESA.

X-ray view of the central region of our Milky Way Galaxy. This image was put together in a new study by compiling all observations of this region that were performed with ESA’s XMM-Newton, adding up to over one month of monitoring in total. The image combines data collected at energies from 0.5 to 2 keV (shown in red), 2 to 4.5 keV (shown in green) and 4.5 to 12 keV (shown in blue). It spans about 2.5 degrees across, equivalent to about 1,000 light-years. Image credit: ESA / XMM-Newton / G. Ponti et al.

A noticeable feature of the Atlantis basin is the several hundred mesas and small peaks strewn ‘chaotically’ across its roughly 200-km expanse. The uppermost layer of these elevated areas consists of light-colored material. Spectroscopic measurements have shown these consist of phyllosilicates, minerals produced in the presence of water.

These Hubble images show elliptical galaxies with dark, wispy dust lanes, the signature of a recent galaxy merger. The dust is the only relic of a smaller galaxy that was consumed by the larger elliptical galaxy. The X in the images marks the location of supernova explosions that are associated with the galaxies. Each supernova may have been gravitationally kicked out of its host galaxy by a pair of central supermassive black holes. When two galaxies merge, so do their supermassive black holes. Prof Foley suggests the supernovae were stars that were once part of double-star systems. These systems wandered too close to the binary black holes, which ejected them from their galaxies. Eventually, the stars in each system moved close enough together to trigger a supernova blast. These outcast supernovae are located at various distances from their home galaxies. SN 2000ds (left) is at least 12,000 light-years from its galaxy, NGC 2768; SN 2005cz (right) is at least 7,000 light-years from its galaxy, NGC 4589. NGC 2768 resides 75 million light-years from Earth, and NGC 4589 is 108 million light-years away. Image credit: NASA / ESA / R. Foley, University of Illinois.

Reddish streaks cut across the surface of Tethys in this image. The streaks are narrow, curved lines on the moon’s surface, only a few miles wide but several hundred miles long. The yellowish tones on the left side of the view are a result of alteration of the moon’s surface by high-energy particles from Saturn’s magnetosphere. This particle radiation slams into the moon’s trailing hemisphere, modifying it chemically and changing its appearance in enhanced-color views like this one. The area of Tethys shown here is centered on 30 degrees north latitude, 187 degrees west longitude, and measures 305 by 258 miles (490 by 415 km) across. The original color images were obtained at a resolution of about 2,300 feet (700 m) per pixel on April 11, 2015. Image credit: NASA / JPL-Caltech / Space Science Institute.
