While this lovely image contains hundreds of distant stars and galaxies, one vital thing is missing - the object Hubble was actually studying at the time! This is not because the target has disappeared. The telescope's camera actually uses two detectors: the first captures the object being studied - in this case an open star cluster known as NGC 299 - while the other detector images the patch of space just 'beneath' it. This is what can be seen here. Technically, this picture is merely a sidekick of the actual object of interest - but space is bursting with activity, and this field of bright celestial bodies offers plenty of interest on its own. It may initially seem to show just stars, but a closer look reveals many of these tiny objects to be galaxies. The spiral galaxies have arms curving out from a bright center. The fuzzier, less clearly shaped galaxies might be ellipticals. Some of these galaxies contain millions or even billions of stars, but are so distant that all of their starry residents are contained within just a small pinprick of light that appears to be the same size as a single star! The bright blue dots are very hot stars, sometimes distorted into crosses by the struts supporting Hubble's secondary mirror. The redder dots are cooler stars, possibly in the red giant phase when a dying star cools and expands.

The tenth SpaceX cargo resupply launch to the International Space Station (@ISS), targeted for launch Feb. 18, will deliver SAGE III to measure stratospheric ozone, aerosols, and other trace gases by locking onto the sun or moon and scanning a thin profile of the atmosphere. Understanding these measurements will allow national and international leaders to make informed policy decisions regarding the protection and preservation of Earth's ozone layer. Ozone in the atmosphere protects Earth's inhabitants, including humans, plants and animals, from harmful radiation from the sun, which can cause long-term problems such as cataracts, cancer and reduced crop yield.  During Expedition 45, ESA astronaut Andreas Mogensen captured pictures of blue jets, elusive electrical discharges in the upper atmosphere, with the most sensitive camera on the orbiting outpost to look for these brief features.

The Andromeda constellation is home to the pictured galaxy. Many different classifications are used to identify galaxies by shape and structure - this one is a barred spiral type. These are recognizable by their spiral arms, which fan out not from a circular core, but from an elongated bar cutting through the galaxy's center. There is evidence that this galaxy has experienced some kind of interaction in its past. Galaxies contain vast amounts of mass, and therefore affect one another via gravity. Sometimes these interactions can be mild, and sometimes hugely dramatic, with two or more colliding and merging into a new, bigger galaxy. Understanding the history of a galaxy, and what interactions it has experienced, helps astronomers to improve their understanding of how galaxies - and the stars within them - form.

This artist's concept shows a massive, comet-like object falling toward a white dwarf. New Hubble Space Telescope findings are evidence for a belt of comet-like bodies orbiting the white dwarf, similar to our solar system's Kuiper Belt. The findings also suggest the presence of one or more unseen surviving planets around the white dwarf, which may have perturbed the belt to hurl icy objects into the burned-out star.

Jupiter from below! This enhanced-color image of Jupiter's south pole and its swirling atmosphere was created by citizen scientist Roman Tkachenko using data from the JunoCam imager on our Juno spacecraft. Juno acquired the image, looking directly at the Jovian south pole, on February 2, 2017, at 6:06 a.m. PST (9:06 a.m. EST) from an altitude of about 63,400 miles (102,100 kilometers) above Jupiter's cloud tops. Cyclones swirl around the south pole, and white oval storms can be seen near the limb -- the apparent edge of the planet.

Comet hunters still have a chance to see comet 45P/Honda-Mrkos-Pajdušáková in the next few days using binoculars or a telescope. It's the first of a trio of comets that will -- between now and the end of 2018 -- pass close enough to Earth for backyard observers to try to spot and for scientists to study using ground-based instruments.  This image of Comet 45P/Honda-Mrkos-Pajdušáková was captured using a telescope on December 22 from Farm Tivoli in Namibia, Africa.

Spectacular displays of nature!  The is a night view of Hawaii's Kilauea Volcano, one of Earth's most active volcanoes, drawing scientists and tourists alike from all over the world to study and witness. This month, a NASA-led science team is exploring Kilauea and the adjacent volcano Mauna Loa from the air, ground and space. Their goal: to better understand volcanic processes and hazards.

Good morning! A sunrise photo of Edwards Air Force Base's Rogers Dry Lake was taken after heavy rainfall in southern California. Our Armstrong Flight Research Center is seen in the foreground. Rogers Dry Lake is a 44-square-mile area used for aviation research and test operations. An additional 22 square miles of similar smooth clay surface is provided by nearby Rosamond Dry Lake. Rogers Dry Lake is the larger of the two and has been used as the landing site for early space shuttle test and operational flights. Both lakebeds have been used for emergency and test landings of aircraft for more than 50 years. Rogers Dry Lake has been declared a National Historic Landmark by the National Park Service, U.S. Department of Interior, because of its role in the development of the nation's space program and in the development of aerospace systems.

[Artist Concept] Black Hole Meal Sets Record for Duration And Size: A giant black hole ripped apart a star and then gorged on its remains for about a decade, according to astronomers. This is more than ten times longer than any observed episode of a star's death by black hole. The trio of orbiting X-ray telescopes found evidence for a "tidal disruption event" (TDE), wherein the tidal forces due to the intense gravity from a black hole can destroy an object - such as a star - that wanders too close. During a TDE, some of the stellar debris is flung outward at high speeds, while the rest falls toward the black hole. As it travels inwards to be ingested by the black hole, the material heats up to millions of degrees and generates a distinct X-ray flare.  Artist's illustration depicts what astronomers call a "tidal disruption event," or TDE.  Credits: Illustration: CXC/M. Weiss  #nasa #space #nasabeyond #astronomy #blackhole #science
A solar prominence rose up along the edge of the sun and twisted and churned for about two days before falling apart (Jan. 23-24, 2017). The dynamic action was generated by competing magnetic forces. The images were taken in a wavelength extreme ultraviolet light that observes activity close to the solar surface, perfect for capturing prominences, which are notoriously unstable clouds of plasma suspended above the sun.

It's known as the Rotten Egg Nebula because it contains a lot of sulphur, an element that, when combined with other elements, smells like a rotten egg - but luckily, it resides over 5,000 light-years away in the constellation of Puppis.  This nebular is a spectacular example of the death of a low-mass star like the sun. Spotted by the Hubble Space Telescope, the image shows the star going through a rapid transformation from a red giant to a planetary nebula, during which it blows its outer layers of gas and dust out into the surrounding space. The recently ejected material is spat out in opposite directions with immense speed - the gas shown in yellow is moving close to one million kilometers per hour (621,371 miles per hour). Astronomers rarely capture a star in this phase of its evolution because it occurs within the blink of an eye - in astronomical terms. Over the next thousand years the nebula is expected to evolve into a fully-fledged planetary nebula.

This image taken Jan. 30 and received on Earth today by our Cassini spacecraft is of Saturn's moon Mimas. Less than 123 miles (198 km) in mean radius, crater-covered Mimas is the smallest and innermost of Saturn's major moons. It is not quite big enough to hold a round shape, so it is somewhat ovoid with dimensions of 129 x 122 x 119 (miles 207 x 197 x 191 km, respectively). Its low density suggests that it consists almost entirely of water ice, which is the only substance ever detected on Mimas. Most of the Mimas surface is saturated with impact craters ranging in size up to greater than 25 miles (40 km) in diameter.

Saturn's moon Dione's lit hemisphere faces away from our Cassini spacecraft's camera, yet the moon's darkened surface features are dimly illuminated in this image, due to Saturnshine, light reflected off of Saturn. In this image, Dione (698 miles or 1,123 kilometers across) is above Saturn's day side, and the moon's night side is faintly illuminated by sunlight reflected off the planet's disk.
