Challenging our understanding of the Universe
Challenging our understanding of the Universe
The European Space Agency's Planck mission with the support of University astronomers has compiled the most detailed map ever created of the cosmic microwave background (the relic radiation from the Big Bang). The new map refines our understanding of the Universe's composition and evolution, and unveils new features that could challenge the foundations of our current understanding of its evolution.

Planck gives earliest snapshot of the Universe
Planck gives earliest snapshot of the Universe
A new map of the radiation left behind after the Big Bang is providing scientists with fresh insights into how our Universe formed. Europe's Planck satellite, a flagship mission for the UK Space Agency, has compiled the most detailed map ever of this leftover radiation - called the cosmic microwave background (CMB).

Space telescope challenges understanding of the Universe
Space telescope challenges understanding of the Universe
Europe's Planck space telescope, which University of Manchester scientists at the Jodrell Bank Observatory helped build, has compiled the most detailed map of the post-Big Bang Universe ever recorded and thrown up anomalies that current physics cannot yet explain. But the data – released today (Thursday) by the European Space Agency – also provides the best evidence yet to support the standard model of cosmology, dates the Universe at 13.82 billion years and refines our knowledge of the Universe's composition and evolution.

Los Alamos science sleuth on the trail of a martian mystery
Los Alamos science sleuth on the trail of a martian mystery
When it comes to examining the surface of rocks on Mars with a high-powered laser, five is a magic number for LANL postdoctoral researcher Nina Lanza. If we can find a reason for this widespread alteration of the surface of Martian rocks, it will tell us something about the Martian environment and the amount of water present there.

Young supernova remains found by U-M astronomer
Young supernova remains found by U-M astronomer
ANN ARBOR-The remnants of a supernova-among the youngest ever found in the Milky Way-have been discovered by a University of Michigan astronomer. The finding will enable astronomers to learn about the nature of the original star and the details of its demise. The object is named G306.3-0.9, after the coordinates of its sky position near the southern border of the constellation Centaurus.

Remnants of a shattered star discovered in Milky Way
UNIVERSITY PARK, Pa. Remnants of an exploded star have been discovered in our Milky Way galaxy by a team of scientists including astronomers at Penn State. The "supernova remnant" was discovered during an extensive X-ray survey of our galaxy's central regions with NASA's Swift satellite, for which science and flight operations are controlled by Penn State from the Mission Operations Center on the University Park campus.

’Nuisance’ data lead to surprising star-birth discovery
When a batch of bright cosmic objects first appeared in maps in 2008 made with data from the South Pole Telescope , astronomers at the University of Chicago's Kavli Institute for Cosmological Physics regarded it only as an unavoidable nuisance. The light sources interfered with efforts to measure more precisely the cosmic microwave background—the afterglow of the big bang.

ALMA rewrites history of Universe's stellar baby boom
Observations with the Atacama Large Millimeter/submillimeter Array (ALMA) show that the most vigorous bursts of star birth in the cosmos took place much earlier than previously thought. The results are published in a set of papers to appear and in the Astrophysical Journal. The research is the most recent example of the discoveries coming from the new international ALMA observatory, which celebrates its inauguration today.

Bursts of Star Formation in the Early Universe
Bursts of Star Formation in the Early Universe
Galaxies have been experiencing vigorous bursts of star formation from much earlier in cosmic history than previously thought, according to new observations by a Caltech-led team. These so-called starburst galaxies produce stars at a prodigious rate-creating the equivalent of a thousand new suns per year.

Beyond the blinding starlight
Study reveals chemical composites of exoplanet atmospheres 128 light years away. Scientists say techniques will "one day provide evidence of life beyond Earth". The really exciting thing is that, one day, the techniques we've developed will give us our first secure evidence of the existence of life on a planet outside our solar system Ian Parry Astronomers have conducted the first remote reconnaissance of a distant solar system, using new telescope imaging techniques to reveal the chemical composition of exoplanets orbiting a star 128 light years from Earth.

Auroras shine light on solar flares
Astrophysicists at the University of Glasgow are looking to the Northern and Southern Lights to expand our understanding of solar flares. In a new paper published in the Astrophysical Journal, researchers from the University's School of Physics and Astronomy suggest magnetic waves, which contribute to the formation of auroras on Earth, could help energy from solar flares travel tens of thousands of kilometres in under a second.

The Liverpool View: Did we discover a Higgs?
July 4th, 2012 – a landmark, red-letter day in a physicist's calendar. It was the day that CERN webcast a special seminar of the latest results from the Large Hadron Collider. It was the day when the world went particle physics mad, celebrating the discovery of the long sought and long elusive Higgs boson.

Physicists demonstrate the acceleration of electrons by a laser in a vacuum
Physicists demonstrate the acceleration of electrons by a laser in a vacuum
David Cline, a distinguished professor in the UCLA Department of Physics and Astronomy, and Xiaoping Ding, an assistant researcher at UCLA, have conducted research at Brookhaven National Laboratory in New York and have established that an electron beam can be accelerated by a laser in free space. This has never been done before at high energies and represents a significant breakthrough, Cline said, adding that it also may have implications for fusion as a new energy source.

Future Evidence for Extraterrestrial Life Might Come from Dying Stars
Future Evidence for Extraterrestrial Life Might Come from Dying Stars
Cambridge, MA - 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.

Mercury may have harbored an ancient magma ocean
Massive lava flows may have given rise to two distinct rock types on Mercury's surface. By analyzing Mercury's rocky surface, scientists have been able to partially reconstruct the planet's history over billions of years. Now, drawing upon the chemical composition of rock features on the planet's surface, scientists at MIT have proposed that Mercury may have harbored a large, roiling ocean of magma very early in its history, shortly after its formation about 4.5 billion years ago.

Tiny planet outside our solar system a big surprise
Tiny planet outside our solar system a big surprise
The detection of a tiny planet has shown for the first time that stars in our galaxy are able to host much smaller planets than anything seen in our own solar system. The existence of the planet, Kepler-37b, the innermost of three planets that orbit the sun-like host star, Kepler-37, is announced in the journal Nature today.

Small sun hosts mini planet in distant solar system
Scientists have detected a rocky planet that is smaller than Mercury, the smallest planet in our solar system, orbiting a solar-type star 80% of the size and mass of the Sun, according to research published today (Wednesday 20 February 2013). The exact dimensions of the star, and the absolute size of the planet, were determined by asteroseismologists led by the University of Birmingham.

Smallest known planet -- smaller than Mercury
Smallest known planet -- smaller than Mercury
A team of scientists including two Yale University astronomers has discovered the smallest planet yet detected. "With this discovery we now have an inventory of planets that are both much larger than Earth and also much smaller than Earth," said Sarbani Basu , professor of astronomy at Yale and a member of the team.
