GN-z10-1 in the GOODS-N field: This image shows an ultra-bright young galaxy known as GN-z10-1, discovered in the Hubble GOODS North field (Great Observatories Origins Deep Survey). Researchers found four unusually red objects, including GN-z10-1, that appear as they existed just 500 million years after the Big Bang. They appear red because their light has been stretched to longer infrared wavelengths by the expansion of the Universe. These extremely compact and bright galaxies present a puzzle to researchers because they are  much more luminous than anything previously seen at such an early epoch. The young galaxies are bright because they are forming stars at a much faster rate than for other galaxies found at such early times.

Galaxy cluster Abell 1689: This image shows galaxy cluster Abell 1689. Astronomers have used the sharp eye of the NASA/ESA Hubble Space Telescope and the magnification power of this giant cluster to find 58 remote galaxies, which produced the bulk of new stars during the Universe's early years. They are the smallest, faintest, and most numerous galaxies ever seen in the remote Universe. This image is a blend of exposures taken by Hubble's Advanced Camera for Surveys and Wide Field Camera 3.

Distant galaxies behind Abell 1689: This image shows a number of distant galaxies behind the galaxy cluster Abell 1689.  Astronomers have used the sharp eye of the NASA/ESA Hubble Space Telescope and the magnification power of the giant cluster to find 58 remote galaxies, which produced the bulk of new stars during the Universe's early years. They are the smallest, faintest, and most numerous galaxies ever seen in the remote Universe.

Hubble captures stellar clockwork motion in nearby galaxy: This illustration shows NASA/ESA Hubble Space Telescope measurements of the rotation of the Large Magellanic Cloud (LMC), the nearest visible galaxy to our Milky Way galaxy. The LMC appears in the Southern sky, as seen in this ground-based photo. The image contrast was enhanced to highlight the LMC's faint outer regions, which are not visible to the naked eye. To illustrate the LMC's large apparent size on the sky, an image of the full moon is shown at bottom right. A horizon has been added for perspective. The red arrows represent the highest-quality Hubble measurements of the motion of the LMC's stars to show how this galaxy rotates. Each arrow reveals the predicted motion over the next 7 million years. The motion of the stars measured by Hubble over a few years' time are a million times smaller than the length of each arrow. The LMC completes a rotation every 250 million years.

Circumstellar disks HD 141943 and HD 191089: The two panels at the top of this image reveal debris discs around young Sun-like stars. These were uncovered in archival images taken by the NASA/ESA Hubble Space Telescope. Hubble's Near Infrared Camera and Multi-object Spectrometer observed these discs in near-infrared in 2007. Astronomers blocked out the bright light from each star in order to analyse the faint light reflected off dust particles in the discs. The illustration beneath each image depicts the orientation of the debris discs. Astronomers retrieved these images from the Barbara A. Mikulski Archive for Space Telescopes (MAST) and used more powerful image analysis techniques to search for planetary systems. NASA Press release

Hubble sees Mars-bound comet sprout multiple jets: Comet Siding Spring is plunging toward the Sun along a roughly 1-million-year orbit. The comet, discovered in 2013, was within the radius of Jupiter's orbit when the Hubble Space Telescope photographed it on March 11, 2014. Hubble resolves two jets of dust coming from the solid icy nucleus. These persistent jets were first seen in Hubble pictures taken on Oct. 29, 2013. The feature should allow astronomers to measure the direction of the nucleus's pole, and hence, rotation axis. The comet will make its closest approach to our Sun on Oct. 25, 2014, at a distance of 130 million miles, well outside Earth's orbit. On its inbound leg, Comet Siding Spring will pass within 84,000 miles of Mars on Oct. 19, 2014, which is less than half the Moon's distance from Earth. The comet is not expected to become bright enough to be seen by the naked eye.
