Ice core shows North American ice sheet's retreat affected Antarctic weather
Ice core shows North American ice sheet’s retreat affected Antarctic weather
Researchers at the University of Washington were among the co-authors of a new study that uses ice core data to see how Earth's climate behaved at the end of the last ice age, when the Laurentide Ice Sheet covering much of North America retreated about 16,000 years ago. The study led by the University of Colorado Boulder is published online this week and will be in the Feb.

Intense laser experiments provide first evidence that light can stop electrons
Intense laser experiments provide first evidence that light can stop electrons
By hitting electrons with an ultra-intense laser, researchers have revealed dynamics that go beyond 'classical' physics and hint at quantum effects. Whenever light hits an object, some of the light scatters back from the surface of the object. However, if the object is moving extremely fast, and if the light is incredibly intense, strange things can happen.

Watery worlds: UW astronomer Eric Agol assists in new findings of TRAPPIST-1 planetary system
A team of astronomers including Eric Agol of the University of Washington has found that the seven Earth-sized planets orbiting the star TRAPPIST-1 are all made mostly of rock, and some could even have more water - which can give life a chance - than Earth itself. The research was led by Simon Grimm of the University of Bern in Switzerland, and published Feb.

Stellar winds behaving unexpectedly
Stellar winds behaving unexpectedly
ESA's XMM-Newton has spotted surprising changes in the powerful streams of gas from two massive stars, suggesting that colliding stellar winds don't behave as expected. Massive stars - several times larger than our Sun - lead turbulent lives, burning their nuclear fuel rapidly and pouring large amounts of material into their surroundings throughout their short but sparkling lives.

New study challenges popular theory about dwarf galaxies
Cold dark matter theory made astronomers believe that the best studied galaxies in the Universe - the Milky Way and Andromeda - are the odd ones out. A new international study involving ANU has found a plane of dwarf galaxies orbiting around Centaurus A in a discovery that challenges a popular theory about how dwarf galaxies are spread around the Universe.  Co-researcher Associate Professor Helmut Jerjen from ANU said astronomers had previously observed planes of dwarf galaxies whirling around our galaxy, the Milky Way, and the neighbouring Andromeda.

Zero gravity graphene promises success in space
In a series of experiments conducted last month, Cambridge researchers experienced weightlessness testing graphene's application in space. This is the first time that graphene has been tested in space-like applications. Andrea Ferrari Working as part of a collaboration between the Graphene Flagship and the European Space Agency, researchers from the Cambridge Graphene Centre tested graphene in microgravity conditions for the first time while aboard a parabolic flight - often referred to as the 'vomit comet'.

A new 'atmospheric disequilibrium' could help detect life on other planets
A new ’atmospheric disequilibrium’ could help detect life on other planets
As NASA's James Webb Space Telescope and other new giant telescopes come online they will need novel strategies to look for evidence of life on other planets. A University of Washington study has found a simple approach to look for life that might be more promising than just looking for oxygen. The paper, published Jan.

Wrong way, hot Jupiter
ANN ARBOR-A giant planet's unexpected wind direction is presenting a mystery for astronomers that could upend what researchers have understood about the atmospheres of these types of planets. "Hot Jupiters" are distant planets that, like our Jupiter, are very large and gaseous. But unlike our Jupiter, they orbit their host stars very closely-closer than Mercury orbits our own sun.

A ’hot Jupiter’ with unusual winds
The hottest point on a gaseous planet near a distant star isn't where astrophysicists expected it to be - a discovery that challenges scientists' understanding of the many planets of this type found in solar systems outside our own. Unlike our familiar planet Jupiter, so-called hot Jupiters circle astonishingly close to their host star - so close that it typically takes fewer than three days to complete an orbit.  And one hemisphere of these planets always faces its host star, while the other faces permanently out into the dark.

Neutron-star merger yields new puzzle for astrophysicists
The afterglow from the distant neutron-star merger detected last August has continued to brighten - much to the surprise of astrophysicists studying the aftermath of the massive collision that took place about 138 million light years away and sent gravitational waves rippling through the universe. New observations from NASA's orbiting Chandra X-ray Observatory , reported in Astrophysical Journal Letters , indicate that the gamma ray burst unleashed by the collision is more complex than scientists initially imagined.

Five tightly packed exoplanets
Five tightly packed exoplanets
Five new planets have been discovered outside our solar system, all orbiting a sun-like star located within the constellation Aquarius, nearly 620 light years from Earth. The alien worlds are considered super-Earths, sizing in at two to three times larger than our own blue planet. All five exoplanets are likely scorchingly hot: Each planet comes incredibly close to its star, streaking around in just 13 days at most - a whirlwind of an orbit compared with Earth's 365-day year.
