April 26, 2013: Albert Einstein's Theory of Relativity Proved Right Once Again

Albert Einstein's theory of relativity has stood the test of time and a recent study by an international team of astronomers and 7,000 light years of space have once again proved he's been right all along. Scientists measured bursts of energy from a super-dense neutron star to put the General Theory of Relativity, which was first published in 1915, through its toughest test yet. According to the study, which was published in the April 26 issue of Science, the experiment showed gravity crumpled spacetime in just the way Albert Einstein predicted in his theory.

April 24, 2013: “Standard candle” supernova extraordinarily magnified by gravitational lensing

A team of researchers at the Kavli Institute for the Physics and Mathematics of the Universe (IPMU) led by Robert Quimby has identified what may prove to be the first ever type Ia supernova (SNIa) magnified by a strong gravitational lens. In this work, the “standard candle” property of type Ia supernovae is used to directly measure the magnification due to gravitational lensing. This provides the first glimpse of the science that will soon come out of dark matter and dark energy studies derived from deep, wide-field imaging surveys.

April 24, 2013: "Two Water Worlds Unlike Anything in Our Solar System" --Found Orbiting a Kepler-Mission Star

Astronomers have a "Water World" planetary system orbiting the star Kepler-62. This five-planet system has two worlds in the habitable zone — the distance from their star at which they receive enough light and warmth that liquid water could theoretically exist on their surfaces. Modeling by researchers at the Harvard-Smithsonian Center for Astrophysics (CfA) suggests that both planets are water worlds, their surfaces completely covered by a global ocean with no land in sight.

April 17, 2013: Dark Matter Signals Recorded in Minnesota Mine

More hints of dark matter have emerged from the Cryogenic Dark Matter Search (CDMS), which hunts for the theorized particles from the depths of a mine in Minnesota. Eight silicon detectors recorded three events that may represent collisions from weakly interacting massive particles, or WIMPs. Physicists have found hints of the existence of WIMPs before, but they remain elusive. Two other possible detections from the CDMS search, reported in 2010, turned out to be indistinguishable from background collisions from other, non-WIMP, sources. The same may yet hold true for the latest findings.

April 5, 2013: Shining light on elusive dark matter

AMS-02, the Alpha Magnetic Spectrometer, consists of seven instruments that monitor cosmic rays from space. Unprotected by Earth's atmosphere the instruments receive a constant barrage of high-energy particles. As these particles pass through AMS-02, the instruments record their speed, energy and direction. The project is one of the largest scientific collaborations of all time involving 56 institutes from 16 countries. The instrument was tested at ESA's technical facility ESTEC in the Netherlands before being shipped to the US for launch on Space Shuttle Endeavour. As part of his DAMA mission, ESA astronaut Roberto Vittori controlled the Shuttle's robotic arm that transferred the 6918 kg instrument to the International Space Station in 2011.

April 5, 2013: Hubble telescope breaks record for furthest supernova

"This new distance record holder opens a window into the early Universe, offering important new insights into how these supernovae form," said astronomer David O. Jones of The Johns Hopkins University in Baltimore, Md., lead author on the science paper detailing the discovery. "At that epoch, we can test theories about how reliable these detonations are for understanding the evolution of the Universe and its expansion." One of the debates surrounding Type Ia supernovae is the nature of the fuse that ignites them. This latest discovery adds credence to one of two competing theories of how they explode. Although preliminary, the evidence favours the explosive merger of two burned out stars—small, dim, and dense stars known as white dwarfs, the final state for stars like our Sun.

April 5, 2013: ALMA detects signs of star formation surprisingly close to galaxy's supermassive black hole

The center of our galaxy, 27,000 light-years away in the direction of the constellation Sagittarius, is home to a monstrous black hole with a mass of four million suns. Extending outward from this gravitational behemoth for many light-years is a turbulent region of space that is thought to be wracked by such extreme tidal forces that any star-forming clouds of dust and gas would be stretched thin and shredded long before infant stars could emerge. Yet against these extreme odds, ALMA spotted telltale jets of material bursting out of what appear to be dense cocoons of gas and dust. These jets, if they were observed in more placid surroundings, would indicate the formation of a young star. The results were accepted for publication in the Astrophysical Journal Letters.

April 4, 2013: Gravity-bending find leads to Kepler meeting Einstein

The dead star, called a white dwarf, is the burnt-out core of what used to be a star like our sun. It is locked in an orbiting dance with its partner, a small "red dwarf" star. While the tiny white dwarf is physically smaller than the red dwarf, it is more massive. "This white dwarf is about the size of Earth but has the mass of the sun," said Phil Muirhead of the California Institute of Technology, Pasadena, lead author of the findings to be published April 20 in the Astrophysical Journal. "It's so hefty that the red dwarf, though larger in physical size, is circling around the white dwarf."

March 29, 2013: Astronomers discover a new kind of supernova

Until now, supernovae came in two main “flavors.” A core-collapse supernova is the explosion of a star about 10–100 times as massive as our Sun while a type Ia supernova is the complete disruption of a tiny white dwarf. Today, astronomers are reporting their discovery of a new kind of supernova called type Iax. This new class is fainter and less energetic than type Ia. Although both varieties come from exploding white dwarfs, type Iax supernovae may not completely destroy the white dwarf.

March 21, 2013: Planck Mission Brings Universe Into Sharp Focus

The Planck space mission has released the most accurate and detailed map ever made of the oldest light in the universe, revealing new information about its age, contents and origins. Planck is a European Space Agency mission. NASA contributed mission-enabling technology for both of Planck's science instruments, and U.S., European and Canadian scientists work together to analyze the Planck data. The map results suggest the universe is expanding more slowly than scientists thought, and is 13.8 billion years old, 100 million years older than previous estimates. The data also show there is less dark energy and more matter, both normal and dark matter, in the universe than previously known. Dark matter is an invisible substance that can only be seen through the effects of its gravity, while dark energy is pushing our universe apart. The nature of both remains mysterious.

March 21, 2013: Astronomers find water vapour in atmosphere of distant planet

Astronomers have detected water vapour and carbon monoxide in the atmosphere of a planet 130 light years away from Earth. However, the planet, known only as HR8799c, is devoid of methane, a gas that can indicate life, the researchers said. Their analysis was performed using the most precise atmospheric measurements ever made of a planet outside our solar system. The levels of gases shed light on how the planet formed, from a cluster of ice crystals tens of millions of years ago.

March 12, 2013: NASA Rover Finds Conditions Once Suited for Ancient Life on Mars

An analysis of a rock sample collected by NASA's Curiosity rover shows ancient Mars could have supported living microbes. Scientists identified sulfur, nitrogen, hydrogen, oxygen, phosphorus and carbon -- some of the key chemical ingredients for life -- in the powder Curiosity drilled out of a sedimentary rock near an ancient stream bed in Gale Crater on the Red Planet last month. "A fundamental question for this mission is whether Mars could have supported a habitable environment," said Michael Meyer, lead scientist for NASA's Mars Exploration Program at the agency's headquarters in Washington. "From what we know now, the answer is yes."

February 26, 2013: Future Evidence for Extraterrestrial Life Might Come from Dying Stars

Even dying stars could host planets with life -- and if such life exists, we might be able to detect it within the next decade. This encouraging result comes from a new theoretical study of Earth-like planets orbiting white dwarf stars. Researchers found that we could detect oxygen in the atmosphere of a white dwarf's planet much more easily than for an Earth-like planet orbiting a Sun-like star.

January 28, 2013: Baffling pulsar leaves astronomers in the dark

New observations of a highly variable pulsar using the European Space Agency’s (ESA) XMM-Newton are perplexing astronomers. Monitoring this pulsar simultaneously in X-rays and radio waves, astronomers have revealed that this source, whose radio emission is known to switch on and off periodically, exhibits the same behavior, but in reverse, when observed at X-ray wavelengths. It is the first time that a switching X-ray emission has been detected from a pulsar, and the properties of this emission are unexpectedly puzzling. As no current model is able to explain this switching behavior, which occurs within only a few seconds, these observations have reopened the debate about the physical mechanisms powering the emission from pulsars.

January 7, 2013: Thorium could help alien life emerge

Rocky exoplanets orbiting some Sun-like stars in the Milky Way galaxy could be hotter and more geologically active than Earth and its solar-system companions, according to researchers in the US. The team looked at the abundance of radioactive elements such as thorium, which heat the interior of planets as they decay and thereby play an important role in how planets evolve. The team concluded that planets that are richer in thorium than Earth could be good candidates for the development of life – making them targets for study by astrobiologists and exoplanet hunters.

December 30, 2012: WMAP releases final results on the infant universe

Since its launch in 2001, the Wilkinson Microwave Anisotropy Probe (WMAP) space mission has revolutionized our view of the universe, establishing a cosmological model that explains a widely diverse collection of astronomical observations. Led by Johns Hopkins astrophysicist Charles L. Bennett, the WMAP science team has determined, to a high degree of accuracy and precision, not only the age of the universe, but also the density of atoms, the density of all other non-atomic matter, the epoch when the first stars started to shine, the “lumpiness” of the universe, and how that “lumpiness” depends on scale size.

December 30, 2012: Hubble Sees Superthin Galaxy IC 2233

Typical spiral galaxies are usually made up of three principal visible components: the disk where the spiral arms and most of the gas and dust is concentrated; the halo, a rough and sparse sphere around the disk that contains little gas, dust or star formation; and the central bulge at the heart of the disk, which is formed by a large concentration of ancient stars surrounding the Galactic Center. The galaxy, labeled IC 2233, is far from being typical. IC 2233, located in the constellation of Lynx some 40 million light-years away, is a prime example of a superthin galaxy. Its diameter is at least ten times larger than the thickness.

The deepest ocean on Earth is the Pacific Ocean's Marianas Trench, which reaches a depth of 6.8 miles awesomely trumped by the depth of the ocean on the Jupiter's moon, Europa, which some measurements put at 62 miles. Although Europa is covered in a thick crust of scarred and cross-hatched ice, measurements made by NASA's Galileo spacecraft and other probes strongly suggest that a liquid ocean lies beneath that surface. The interior is warmed, researchers believe, by the tidal stresses exerted on Europa by Jupiter and several other large moons, as well as by radioactivity.

October 20, 2012: New model reconciles the Moon's Earth-like composition with the giant impact theory of formation

The giant impact believed to have formed the Earth-Moon system has long been accepted as canon. However, a major challenge to the theory has been that Earth and the Moon have identical oxygen isotope compositions, even though earlier impact models indicated they should differ substantially. A new model by the Southwest Research Institute (SwRI) in San Antonio, Texas, motivated by accompanying work by others on the early dynamical history of the Moon, accounts for this similarity in composition while also yielding an appropriate mass for Earth and the Moon.

October 18, 2012: Planet Found in Nearest Star System to Earth

Alpha Centauri is one of the brightest stars in the southern skies and is the nearest stellar system to our Solar System — only 4.3 light-years away. It is actually a triple star — a system consisting of two stars similar to the Sun orbiting close to each other, designated Alpha Centauri A and B, and a more distant and faint red component known as Proxima Centauri [1]. Since the nineteenth century astronomers have speculated about planets orbiting these bodies, the closest possible abodes for life beyond the Solar System, but searches of increasing precision had revealed nothing. Until now.

Since the New Horizons spacecraft left Earth back in 2006, there are a few things we know about the Pluto system now that we didn’t know then. For instance, it was discovered Pluto has two additional small moons – P4 and P5 — and Alan Stern, New Horizons Principal Investigator, said Pluto may have a large system of moons to be discovered as the spacecraft gets get closer. There are also comets, possibly more dwarf planets and other objects out in the Kuiper Belt region where Pluto orbits.

October 18, 2012: Hubble Studies Dark Matter Filament in 3-D

Earlier this year, astronomers using the Hubble Space Telescope were able to identify a slim filament of dark matter that appeared to be binding a pair of distant galaxies together. Now, another filament has been found, and scientists a have been able to produce a 3-D view of the filament, the first time ever that the difficult-to-detect dark matter has been able to be measured in such detail. Their results suggest the filament has a high mass and, the researchers say, that if these measurements are representative of the rest of the Universe, then these structures may contain more than half of all the mass in the Universe.

Astronomers using NASA’s Spitzer Space Telescope have announced the most precise measurement yet of the Hubble constant, or the rate at which our universe is stretching apart. The Hubble constant is named after astronomer Edwin P. Hubble, who astonished the world in the 1920s by confirming our universe has been expanding since it exploded into being 13.7 billion years ago. In the late 1990s, astronomers discovered the expansion is accelerating, or speeding up over time. Determining the expansion rate is critical for understanding the age and size of the universe.

Despite being infamously demoted from its status as a major planet, Pluto (and its largest companion, Charon) recently posed as a surrogate extrasolar planetary system to help astronomers produce exceptionally high-resolution images with the 8-meter Gemini North Telescope. Using a method called reconstructive speckle imaging, the researchers took the sharpest ground-based snapshots ever obtained of Pluto and Charon in visible light, which hint at the exoplanet verification power of a large state-of-the-art telescope when combined with speckle imaging techniques. The data also verified and refined previous orbital characteristics for Pluto and Charon while revealing the pair’s precise diameters.

Sep 14, 2011: 36 Light-Years Away, the Most Earthlike World Yet?

From the very start of the modern planet-hunting era a decade and a half ago, the pioneers in this astronomical subspecialty were up front about saying it wasn't about astronomy; it was about biology. Their colleagues might be happy probing to the edge of the cosmos looking for exotic things like black holes and quasars and dark matter. But the planet hunters were ultimately looking for life on distant worlds. Assuming they were talking about earthlike life — which they were, since it's the only kind we understand — the target planets would have to be earthlike too. That meant they'd have to be about the same size as our home world, orbiting their parent star at about the right distance for water to exist in liquid, life-nurturing form. (Image by ESO)
