Astronomers have found the best evidence yet of the remains of a comet-like object scattered around a burned-out star. They used NASA's Hubble Space Telescope to detect the debris, which has polluted the atmosphere of a compact star known as a white dwarf. The icy object, which has been ripped apart, is similar to Halley's Comet in chemical composition, but it is 100,000 times more massive and has a much higher amount of water. It is also rich in the elements essential for life, including nitrogen, carbon, oxygen, and sulfur. These findings are evidence for a belt of comet-like bodies similar to our solar system's Kuiper Belt orbiting the white dwarf. This is the first evidence of comet-like material polluting a white dwarf's atmosphere. The results also suggest the presence of unseen, surviving planets around the burned-out star.

Since the dawn of civilization, we have gazed into the night sky and attempted to make sense of what we saw there, asking questions such as: Where do we come from? What is our place in the universe? And are we alone? As we ask those questions today and new technology expands our horizons further into space, our yearning for their answers only grows. Since its launch in 1990, NASA's Hubble Space Telescope has continued this quest for answers while orbiting Earth every 90 minutes. Hubble has not only made countless new astronomical discoveries, but also brought astronomy to the public eye, satisfying our curiosity, sparking our imaginations, and greatly impacting culture, society, and art.
A new traveling exhibition, "Our Place in Space" features iconic Hubble images. It presents not only a breathtaking pictorial journey through our solar system and to the edges of the known universe, but also Hubble-inspired works by selected Italian artists. By seamlessly integrating perspectives from both artists and astronomers, the exhibition will inspire visitors to think deeply about how humanity fits into the grand scheme of the universe. Before moving to other venues, the exhibition will be on display from February 1 to April 17, 2017, in the Istituto Veneto di Science, Lettere ed Arti, Palazzo Cavalli Franchetti, on the banks of the Grand Canal in Venice, Italy.

Eerie mysteries in the universe can be betrayed by simple shadows. The wonder of a solar eclipse is produced by the moon's shadow, and over 1,000 planets around other stars have been cataloged by the shadow they cast when passing in front of their parent star. Astronomers were surprised to see a huge shadow sweeping across a disk of dust and gas encircling a nearby, young star. They have a bird's-eye view of the disk, because it is tilted face-on to Earth, and the shadow sweeps around the disk like the hands moving around a clock. But, unlike the hands of a clock, the shadow takes 16 years to make one rotation.
Hubble has 18 years' worth of observations of the star, called TW Hydrae. Therefore, astronomers could assemble a time-lapse movie of the shadow's rotation. Explaining it is another story. Astronomers think that an unseen planet in the disk is doing some heavy lifting by gravitationally pulling on material near the star and warping the inner part of the disk. The twisted, misaligned inner disk is casting its shadow across the surface of the outer disk. TW Hydrae resides 192 light-years away and is roughly 8 million years old.

Interstellar forecast for a nearby star: Raining comets! The comets are plunging into the star HD 172555, which resides 95 light-years from Earth. The comets were not seen directly around the star. Astronomers inferred their presence when they used NASA's Hubble Space Telescope to detect gas that is likely the vaporized remnants of their icy nuclei.
The presence of these doomed comets provides circumstantial evidence for "gravitational stirring" by an unseen Jupiter-size planet, where comets deflected by the massive object's gravity are catapulted into the star. These events also provide new insights into the past and present activity of comets in our solar system. It's a mechanism where infalling comets could have transported water to Earth and the other inner planets of our solar system. HD 172555 represents the third extrasolar system where astronomers have detected doomed, wayward comets. All of these systems are young, under 40 million years old.

In 1977, NASA's Voyager 1 and 2 spacecraft began their pioneering journey across the solar system to visit the giant outer planets. Now, the Voyagers are hurtling through unexplored territory on their road trip beyond our solar system. Along the way, they are measuring the interstellar medium, the mysterious environment between stars that is filled with the debris from long-dead stars. NASA's Hubble Space Telescope is providing the road map, by measuring the material along the probes' trajectories as they move through space. Hubble finds a rich, complex interstellar ecology, containing multiple clouds of hydrogen, laced with other elements. Hubble data, combined with the Voyagers, have also provided new insights into how our sun travels through interstellar space.

Two glowing nebulas in the Small Magellanic Cloud, a dwarf galaxy that is a satellite of our Milky Way galaxy, have been observed by NASA's Hubble Space Telescope. Young, brilliant stars at the center of each nebula are heating hydrogen, causing these clouds of gas and dust to glow red. The image is part of a study called Small Magellanic Cloud Investigation of Dust and Gas Evolution (SMIDGE). Astronomers are using Hubble to probe the Milky Way satellite to understand how dust is different in galaxies that have a far lower supply of heavy elements needed to create dust.

In writer Edgar Allan Poe's short story "The Tell-Tale Heart," a killer confesses his crime after he thinks he hears the beating of his victim's heart. The heartbeat turns out to be an illusion. Astronomers, however, discovered a real "tell-tale heart" in space, 6,500 light-years from Earth. The "heart" is the crushed core of a long-dead star, called a neutron star, which exploded as a supernova and is now still beating with rhythmic precision. Evidence of its heartbeat are rapid-fire, lighthouse-like pulses of energy from the fast-spinning neutron star. The stellar relic is embedded in the center of the Crab Nebula, the expanding, tattered remains of the doomed star.
The nebula was first identified in 1731 and named in 1844. In 1928, Edwin Hubble linked the nebula to a supernova first witnessed in the spring of 1054 A.D. Now, the eerie glow of the burned-out star reveals itself in this new Hubble Space Telescope snapshot of the heart of the Crab Nebula. The green hue, representative of the broad color range of the camera filter used, gives the nebula a Halloween theme.

In Arthur C. Clarke's novel "2001: A Space Odyssey," astronaut David Bowman exclaims, "My God, it's full of stars!" before he gets pulled into an alien-built wormhole in space. When the Hubble Space Telescope made its deepest views of the universe, astronomers might have well exclaimed: "My God, it's full of galaxies!" The Hubble Ultra Deep Field, for example, revealed 10,000 galaxies of various shapes, sizes, colors, and ages, all within an area roughly one-tenth the diameter of the full moon. What's mind-blowing is that these myriad galaxies, though plentiful, may represent merely 10 percent of the universe's total galaxy population. That's according to estimates from a new study of Hubble's deep-field surveys. The study's authors came to the staggering conclusion that at least 10 times more galaxies exist in the observable universe than astronomers thought.
According to the authors, the missing 90 percent of the universe's galaxies are too faint and too far away to be detected by the current crop of telescopes, including Hubble. To uncover them, astronomers will have to wait for much larger and more powerful future telescopes. The researchers arrived at their result by painstakingly converting Hubble deep-field images into 3-D pictures so they could make accurate measurements of the number of galaxies at different epochs in the universe's history.

Great balls of fire! The Hubble Space Telescope has detected superhot blobs of gas, each twice as massive as the planet Mars, being ejected near a dying star. The plasma balls are zooming so fast through space that they would travel from Earth to the moon in 30 minutes. This stellar "cannon fire" has continued once every 8.5 years for at least the past 400 years, astronomers estimate. The fireballs present a puzzle to astronomers because the ejected material could not have been shot out by the host star, called V Hydrae. The star is a bloated red giant, residing 1,200 light-years away, which has probably shed at least half of its mass into space during its death throes.
The current best explanation is that the plasma balls were launched by an unseen companion star in an elliptical orbit around the red giant. The elongated orbit carries the companion every 8.5 years to within the puffed-up atmosphere of V Hydrae, where it gobbles up material from the bloated star. This material then settles into a disk around the companion, and serves as the launching pad for blobs of plasma, which travel at roughly a half-million miles per hour. This star system could explain a dazzling variety of glowing shapes uncovered by Hubble that are seen around dying stars, called planetary nebulae, researchers say.

Astronomers using NASA's Hubble Space Telescope have imaged what may be water vapor plumes erupting off the surface of Jupiter's moon Europa. This finding bolsters other Hubble observations suggesting the icy moon erupts with high altitude water vapor plumes.
Mon, 26 Sep 2016 14:00:00 EDT
New findings from NASA's Hubble Space Telescope show suspected water plumes erupting from Jupiter's icy moon Europa. These observations bolster earlier Hubble work suggesting that Europa is venting water vapor. A team of astronomers, led by William Sparks of the Space Telescope Science Institute in Baltimore, Maryland, observed these finger-like projections while viewing Europa's limb as the moon passed in front of Jupiter. The team was inspired to use this observing method by studies of atmospheres of planets orbiting other stars.
The plumes are estimated to rise about 125 miles before, presumably, raining material back down onto Europa's surface. This is exciting because Europa is a plausible place for life to have developed beyond the Earth. If the venting plumes originate in a subsurface ocean, they could act as an elevator to bring deep-sea life above Europa's surface, where it could be sampled by visiting spacecraft. This offers a convenient way to access the chemistry of that ocean without drilling through miles of ice.

Two is company, but three might not always be a crowd, at least in space. When astronomers found an extrasolar planet orbiting a neighboring star, a detailed analysis of the data uncovered a third body. But astronomers couldn't definitively identify whether the object was another planet or another star in the system.
Now, nine years later, astronomers have used ultra-sharp images from the Hubble Space Telescope to determine that the system consists of a Saturn-mass planet circling two diminutive, faint stars in a tight orbit around each other. The system, called OGLE-2007-BLG-349, resides 8,000 light-years away. Astronomers teased the signature of the three objects using an observational technique called gravitational microlensing. This occurs when the gravity of a foreground star bends and amplifies the light of a background star that momentarily aligns with it. The particular character of the light magnification can reveal clues to the nature of the foreground star and any associated planets.

Comet 332P/Ikeya-Murakami survived for 4.5 billion years in the frigid Kuiper Belt, a vast reservoir of icy bodies on the outskirts of our solar system. The objects are the leftovers from our solar system's construction. But within the last few million years, the unlucky comet was gravitationally kicked to the inner solar system by the outer planets. The comet, dubbed 332P, found a new home, settling into an orbit just beyond Mars. But the new home, closer to the sun, has doomed the comet. Sunlight is heating up Comet 332P's surface, causing jets of gas and dust to erupt. The jets act like rocket engines, spinning up the comet's rotation. The faster spin rate loosened chunks of material, which are drifting off the surface and into space.
The Hubble Space Telescope caught the latest cloud of debris ejected by Comet 332P. The images, taken over three days in January 2016, represent one of the sharpest, most detailed observations of a comet breaking apart. Hubble reveals about 25 building-size chunks from the comet floating through space at roughly the walking speed of an adult. Material will continue to break away from Comet 332P. Astronomers estimate that the comet, which has survived for 4.5 billion years, will be gone in another 150 years.
