Our Hubble Space Telescope image captures Mars-bound comet sprouting multiple jets! On Oct. 19, the comet will pass within 84,000 miles of Mars -- less than half the distance between Earth and our moon. The image shows the comet after image processing techniques were applied to remove the hazy glow of the coma revealing what appear to be two jets of dust coming off the location of the nucleus in opposite directions. This observation should allow astronomers to measure the direction of the nucleus’s pole, and axis of rotation. Image Credit: NASA, ESA, and J.-Y.

Search for Seeds of Black Holes! The galaxy NGC 4395 is shown here in infrared light, captured by our Spitzer Space Telescope. This dwarf galaxy is relatively small in comparison with our Milky Way galaxy, which is nearly 1,000 times more massive. The galaxy is "bulgeless" because it lacks a large collection of stars at its center. Astronomers using NASA's Wide-field Infrared Survey Explorer, or WISE, have found more evidence that bulgeless galaxies, contrary to previous theories, do harbor supermassive black holes at their center. In this image, an actively feeding supermassive black hole resides in the galaxy's nucleus, as seen by the bright red source. The feeding supermassive black hole dominates the infrared light coming from the galaxy's center. Image credit: NASA/JPL-Caltech #blackholes #nasa #galaxy #spitzer #astronomy #wise #space #science; -
Zipping Past Earth! This image of Earth was taken during the close flyby of our Juno spacecraft on Oct. 9, 2013. It was acquired at 19:12 UT at an altitude of 1,987 miles (3,197 kilometers) - just 10 minutes before Juno's closest approach to our planet. The image is a combination of the JunoCam instrument's red, green and blue spectral filters and approximates natural color. The image is a mosaic of 82 individual frames taken as the spacecraft spun. The phote provides a view of the Argentinean coastline at upper left, with reflections, or specular highlights, off the Rio Negro, north of Golfo San Matias. Clouds cover much of Antarctica at bottom. Image credit: NASA/JPL-Caltech/MSSS #nasa #space #juno #jupiter #spacecraft #earth #science; -
A rainfall-triggered landslide near Oso, Washington sent muddy debris spilling on March 22 across the North Fork of the Stillaguamish River. The slide left an earthen dam that blocked the river, causing a barrier lake to form. The Operational Land Imager (OLI) on the Landsat 8 satellite acquired this image of landslide debris and the barrier lake on March 23, 2014.

Off into Space! This long exposure photograph shows the flight path of the Soyuz TMA-12M rocket as it launches from the Baikonur Cosmodrome in Kazakhstan yesterday. The rocket carried Expedition 39 Soyuz Commander Alexander Skvortsov of the Russian Federal Space Agency, Roscosmos, Flight Engineer Steven Swanson of NASA, and Flight Engineer Oleg Artemyev of Roscosmos to the International Space Station. The next trio of crew members destined for the station is now looking forward to a Thursday arrival at the orbiting laboratory after their Soyuz spacecraft was unable to complete its third thruster burn to fine-tune its approach. Flight controllers in the Mission Control Center outside Moscow are now reverting to a backup 34-orbit rendezvous, which would result in an arrival and docking at 7:58 p.m. EDT Thursday, March 27.

Variations in the stuff that cements grains together in sandstone have shaped the landscape surrounding NASA's Curiosity Mars rover and could be a study topic at the mission's next science waypoint. On a journey with many months yet to go toward prime destinations on the lower slope of Mount Sharp, Curiosity is approaching a site called "the Kimberley." Scientists on the team picked this location last year as a likely place to pause for investigation. Its informal name comes from a northwestern Australia region known as the Kimberley. The Martian site's geological appeal, based on images taken from orbit, is that four types of terrain with different rock textures intersect there This Martian scene was recorded by the Mast Camera on NASA's Curiosity Mars rover on Feb. 25, 2014, about one-quarter mile (about 400 meters) from a planned waypoint called "the Kimberley."

Four Moons of Saturn! Two pairs of moons make a rare joint appearance. The F ring's shepherd moons, Prometheus and Pandora, appear just inside and outside of the F ring (the thin faint ring furthest from Saturn). Meanwhile, farther from Saturn the co-orbital moons Janus (near the bottom) and Epimetheus (about a third of the way down from the top) also are captured. This view looks toward the sunlit side of the rings from about 47 degrees above the ringplane. The image was taken in visible light with the Cassini spacecraft wide-angle camera on Oct. 11, 2013. The view was acquired at a distance of approximately 810,000 miles (1.3 million kilometers) from Saturn and at a Sun-Saturn-spacecraft, or phase, angle of 47 degrees. Image scale is 47 miles (76 kilometers) per pixel. Credit: NASA/JPL-Caltech/Space Science Institute #nasa #saturn #moons #cassini @spacecraft #exploration #solarsystem #science; -

As seen on #Cosmos: The next major cosmic event to affect our galaxy, sun, and solar system: the titanic collision of our Milky Way galaxy with the neighboring Andromeda galaxy. The Milky Way is destined to get a major makeover during the encounter, which is predicted to happen four billion years from now. It is likely the sun will be flung into a new region of our galaxy, but our Earth and solar system are in no danger of being destroyed. This illustration shows a stage in the predicted merger between our Milky Way galaxy and the neighboring Andromeda galaxy, as it will unfold over the next several billion years. In this image, representing Earth's night sky in 3.75 billion years, Andromeda (left) fills the field of view and begins to distort the Milky Way with tidal pull. Credit: NASA; ESA; Z.

As seen on #Cosmos: We now know that comets are leftovers from the dawn of our solar system around 4.6 billion years ago, and consist mostly of ice coated with dark organic material. They have been referred to as "dirty snowballs." They may yield important clues about the formation of our solar system. Comets may have brought water and organic compounds, the building blocks of life, to the early Earth and other parts of the solar system. As theorized by astronomer Gerard Kuiper in 1951, a disc-like belt of icy bodies exists beyond Neptune, where a population of dark comets orbits the sun in the realm of Pluto. These icy objects, occasionally pushed by gravity into orbits bringing them closer to the sun, become the so-called short-period comets. Taking less than 200 years to orbit the sun, in many cases their appearance is predictable because they have passed by before. Less predictable are long-period comets, many of which arrive from a region called the Oort Cloud about 100,000 astronomical units (that is,100,000 times the distance between Earth and the Sun) from the Sun. These Oort Cloud comets can take as long as 30 million years to complete one trip around the Sun. Each comet has a tiny frozen part, called a nucleus, often no larger than a few kilometers across. The nucleus contains icy chunks, frozen gases with bits of embedded dust. A comet warms up as it nears the Sun and develops an atmosphere, or coma. The sun's heat causes the comet's ices to change to gases so the coma gets larger. The coma may extend hundreds of thousands of kilometers. The pressure of sunlight and high-speed solar particles (solar wind) can blow the coma dust and gas away from the Sun, sometimes forming a long, bright tail. Comets actually have two tails - a dust tail and an ion (gas) tail. This image of Comet C/2001 Q4 (NEAT) was taken at the WIYN 0.9-meter telescope at Kitt Peak National Observatory near Tucson, Ariz. on 7 May 2004.

As seen on #Cosmos: A spherical shell of icy bodies surrounding the solar system, now named the Oort Cloud, occupies space at a distance between 5,000 and 100,000 astronomical units. (One astronomical unit, or AU, is the mean distance of Earth from the sun: about 150 million km or 93 million miles.) The outer extent of the Oort Cloud is believed to be in the region of space where the sun's gravitational influence is weaker than the influence of nearby stars. The Oort Cloud probably contains 0.1 to 2 trillion icy bodies in solar orbit. Occasionally, giant molecular clouds, stars passing nearby, or tidal interactions with the Milky Way's disc disturb the orbits of some of these bodies in the outer region of the Oort Cloud, causing the object to fall into the inner solar system as a so-called long-period comet. These comets have very large, eccentric orbits and take thousands of years to circle the sun. In recorded history, they are observed in the inner solar system only once. This artist's concept puts solar system distances in perspective. The scale bar is in astronomical units, with each set distance beyond 1 AU representing 10 times the previous distance. One AU is the distance from the sun to the Earth, which is about 93 million miles or 150 million kilometers. Neptune, the most distant planet from the sun, is about 30 AU. Informally, the term "solar system" is often used to mean the space out to the last planet. Scientific consensus, however, says the solar system goes out to the Oort Cloud, the source of the comets that swing by our sun on long time scales. Beyond the outer edge of the Oort Cloud, the gravity of other stars begins to dominate that of the sun. NASA's Voyager 1, humankind's most distant spacecraft, is around 125 AU.
