The main panel of this image shows a wide-field view of NGC 4424 in optical light from Hubble. The image is about 45,000 light-years wide. The inset features a close-up view of NGC 4424 that shows Chandra X-ray data (blue) plus a version of the optical data (red) that has had light from a model of NGC 4424 subtracted from the image to show other faint features. This inset image is about 1,700 light-years across. The Nikhuli star cluster is the elongated red object. Image credit: NASA / CXC / Swinburne University of Technology / Graham et al. / ESA / STScI.

On August 31, 2012, a long filament of solar material that had been hovering in the Sun’s atmosphere, the corona, erupted out into space at 4:36 p.m. EDT. The CME traveled at over 900 miles per second. It did not travel directly toward Earth, but did connect with Earth’s magnetic environment, or magnetosphere, with a glancing blow, causing aurora to appear on the night of September 3.

This illustration plots changes in the brightness of Betelgeuse, following the titanic mass ejection of a large piece of its visible surface; the escaping material cooled to form a cloud of dust that temporarily made the star look dimmer, as seen from Earth; this unprecedented stellar convulsion disrupted the monster star’s 400-day-long oscillation period that astronomers had measured for more than 200 years; the interior may now be jiggling like a plate of gelatin dessert.

This Hubble image shows three galaxies LEDA 58109, SDSS J162558.14+435746.4, and SDSS J162557.25+435743.5. The color image is composed of infrared, optical and ultraviolet observations from Hubble’s Advanced Camera for Surveys (ACS), the Dark Energy Camera (DECam) on the Victor M. Blanco 4-m Telescope, and the Sloan Digital Sky Survey (SDSS). Nine filters were used to sample various wavelengths. The color results from assigning different hues to each monochromatic image associated with an individual filter. Image credit: NASA / ESA / Hubble / W. Keel.

Two cameras aboard Webb captured these images of the Southern Ring Nebula: two stars, which are locked in a tight orbit, shape the local landscape; they are prominent in the image from Webb’s Near-Infrared Camera (NIRCam) on the left, while the image from Webb’s Mid-Infrared Instrument (MIRI) on the right shows for the first time that the second star is surrounded by dust; the brighter star is in an earlier stage of its stellar evolution and will probably eject its own planetary nebula in the future.

This landscape of ‘mountains’ and ‘valleys’ speckled with glittering stars is actually the edge of the Carina Nebula, a huge star-forming region some 7,500 light-years away in the constellation of Carina. Captured in infrared light by Webb, this image reveals for the first time previously invisible areas of star birth. Called the Cosmic Cliffs, Webb’s seemingly 3D picture looks like craggy mountains on a moonlit evening. In reality, it is the edge of the giant, gaseous cavity within the Carina Nebula, and the tallest ‘peaks’ in this image are about 7 light-years high. The cavernous area has been carved from the nebula by the intense ultraviolet radiation and stellar winds from extremely massive, hot, young stars located in the center of the bubble, above the area shown in this image.
