NASA's Hubble Spots Possible Water Plumes Erupting on Jupiter's Moon Europa
Mon, 26 Sep 2016 14:00:00 -0400
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.

Brief but powerful outbursts seen from Comet 67P/Churyumov–Gerasimenko during its most active period last year have been traced back to their origins on the surface.
Hubble Finds Planet Orbiting Pair of Stars
Thu, 22 Sep 2016 10:00:00 -0400
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.
Barry M. Lasker Data Science Fellowship
Fri, 16 Sep 2016 13:00:00 -0400
The Space Telescope Science Institute (STScI) in Baltimore, Maryland, announces the initiation of the Barry M. Lasker Data Science Postdoctoral Fellowship. The Lasker Fellowship is a STScI-funded program designed to provide up to three years of support for outstanding postdoctoral researchers conducting innovative astronomical studies that involve the use or creation of one or more of the following: large astronomical databases, massive data processing, data visualization and discovery tools, or machine-learning algorithms. The first recipient of the fellowship is Dr. Gail Zasowski of the Johns Hopkins University (JHU) in Baltimore, Maryland. The fellowship is named in honor of STScI astronomer Barry M. Lasker (1939-1999).
Hubble Takes Close-up Look at Disintegrating Comet
Thu, 15 Sep 2016 13:00:00 -0400
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.

Hubble Uncovers a Galaxy Pair Coming in from the Wilderness
Thu, 11 Aug 2016 13:00:00 -0400
The galaxies in the early universe were much smaller than our Milky Way and
churned out stars at a rapid pace. They grew larger through mergers with other
dwarf galaxies to eventually build the magnificent spiral and elliptical galaxies we
see around us today. But astronomers using the Hubble Space Telescope have looked at
two small galaxies that were left off the star party list. For many billions of years
Pisces A and Pisces B lived in a vast intergalactic wilderness that was devoid of gas,
which fuels star formation. They got left out in the cold.
NASA's Hubble Looks to the Final Frontier
Thu, 21 Jul 2016 10:00:00 -0400
Celebrating its 50th anniversary this year, the TV series "Star Trek" has captured the
public's imagination with the signature phrase, "To boldly go where no one has gone
before." The Hubble Space Telescope simply orbits Earth and doesn't "boldly go" deep
into space. But it looks deeper into the universe than ever before possible to explore
the fabric of time and space and find the farthest objects ever seen. This is epitomized
in this Hubble image that is part of its Frontier Fields program to probe the far
universe. This view of a massive cluster of galaxies unveils a very cluttered-looking
universe filled with galaxies near and far. Some are distorted like a funhouse mirror
through a warping-of-space phenomenon first predicted by Einstein a century ago.
NASA's Hubble Telescope Makes First Atmospheric Study of Earth-Sized Exoplanets
Wed, 20 Jul 2016 13:00:00 -0400
The possibility of life on other worlds has fueled humankind's imagination for
centuries. Over the past 20 years, the explosion of discoveries of planets orbiting
other stars has sparked the search for worlds like Earth that could sustain life.
Most of those candidates were found with other telescopes, including NASA's
Kepler space observatory. NASA's Hubble Space Telescope has also made
some unique contributions to the planet hunt. Astronomers used Hubble, for
example, to make the first measurements of the atmospheric composition of
A Surprising Planet with Three Suns
Thu, 07 Jul 2016 14:00:00 -0400
A team of astronomers led by the University of Arizona has directly imaged with
the SPHERE instrument on ESO's Very Large Telescope the first planet ever found in
a wide orbit inside a triple-star system. The orbit of such a planet had been expected
to be unstable, probably resulting in the planet being quickly ejected from the
system. But somehow this one survives. This observation of the HD 131399 system
suggests that such systems may actually be more common than previously thought.
The results will be published online in the journal Science on July 7, 2016. The
artist's impression shows a view of the triple-star system HD 131399 from the giant
planet orbiting the system. The planet is HD 131399Ab and appears at the lower left
of the picture.
Hubble Captures the Beating Heart of the Crab Nebula
Thu, 07 Jul 2016 10:00:00 -0400
At the center of the Crab Nebula, located in the constellation Taurus, lies a
celestial "beating heart" that is an example of extreme physics in space. The tiny
object blasts out blistering pulses of radiation 30 times a second with
unbelievable clock-like precision. Astronomers soon figured out that it was the
crushed core of an exploded star, called a neutron star, which wildly spins like a
blender on puree. The burned-out stellar core can do this without flying apart
because it is 10 billion times stronger than steel. This incredible density means
that the mass of 1.4 suns has been crushed into a solid ball of neutrons no
bigger than the width of a large city. This Hubble image captures the region
around the neutron star. It is unleashing copious amounts of energy that are
pushing on the expanding cloud of debris from the supernova explosion like an
animal rattling its cage. This includes wave-like tsunamis of charged particles
embedded in deadly magnetic fields.
