UW research instrument returns from 22,000-mile seaward journey
For News Media FOR IMMEDIATE RELEASE 1/15/19 × A portable research lab known as SPARCLET, developed at UW-Madison, traveled aboard the research vessel Thomas G. Thompson for two months to aid in a study aimed at better understanding how pollutants and turbulent conditions over the Philippine Sea affect the region and influence global weather.

Measurement of five flashes from the depths of the universe
Measurement of five flashes from the depths of the universe
First-time precise measurement of gamma-ray bursts conducted successfully from a space station A detector called POLAR, developed at PSI, has been sent to outer space to collect data. In September 2016, the device was launched into Earth orbit on board the newest Chinese space station. From that vantage point, POLAR recorded so-called gamma-ray bursts flashing in the far reaches of the universe.

Ricocheting Black Hole Jet Discovered by Chandra
Astronomers have discovered behavior by a jet from a giant black hole that has never been seen before. Using NASA's Chandra X-ray Observatory they have observed a jet that bounced off a wall of gas and then punched a hole in a cloud of energetic particles. This behavior can tell scientists more about how jets from black holes interact with their surroundings.

Double Star System Flips Planet-Forming Disk into Pole Position
Harvard & Smithsonian has found the first confirmed example of a double star system that has flipped its surrounding disc to a position that leaps over the orbital plane of those stars. The international team of astronomers used the Atacama Large Millimeter/sub-millimeter Array (ALMA) to obtain high-resolution images of the Asteroid belt-sized disc.

Team of telescopes finds X-ray engine inside mysterious supernova
Team of telescopes finds X-ray engine inside mysterious supernova
ESA's high-energy space telescopes Integral and XMM-Newton have helped to find a source of powerful X-rays at the centre of an unprecedentedly bright and rapidly evolving stellar explosion that suddenly appeared in the sky earlier this year. The ATLAS telescope in Hawaii first spotted the phenomenon, since then named AT2018cow, on 16 June.

Signatures of a 'messy' star that made its companion go supernova
Signatures of a ’messy’ star that made its companion go supernova
Many stars explode as luminous supernovae when, swollen with age, they run out of fuel for nuclear fusion. But some stars can go supernova simply because they have a close and pesky companion star that, one day, perturbs its partner so much that it explodes. These latter events can happen in binary star systems, where two stars attempt to share dominion.

Gaia reveals how Sun-like stars turn solid after their demise
Gaia reveals how Sun-like stars turn solid after their demise
Data captured by ESA's galaxy-mapping spacecraft Gaia has revealed for the first time how white dwarfs, the dead remnants of stars like our Sun, turn into solid spheres as the hot gas inside them cools down. This process of solidification, or crystallisation, of the material inside white dwarfs was predicted 50 years ago but it wasn't until the arrival of Gaia that astronomers were able to observe enough of these objects with such a precision to see the pattern revealing this process.

X-ray pulse detected near event horizon as black hole devours star
X-ray pulse detected near event horizon as black hole devours star
Pulse pattern suggests distant black hole must be spinning at least at 50 percent the speed of light. On Nov. 22, 2014, astronomers spotted a rare event in the night sky: A supermassive black hole at the center of a galaxy, nearly 300 million light-years from Earth, ripping apart a passing star. The event, known as a tidal disruption flare, for the black hole's massive tidal pull that tears a star apart, created a burst of X-ray activity near the center of the galaxy.

After mapping millions of galaxies, Dark Energy Survey finishes data collection
For the past six years, Fermi National Accelerator Laboratory has been part of an international effort to create an unprecedented survey of distant galaxies and better understand the nature of dark energy-the mysterious force accelerating the expansion of the universe. After scanning about a quarter of the southern skies over 800 nights, the Dark Energy Survey finished taking data on Jan.

Astronomers observe evolution of a black hole as it wolfs down stellar
Astronomers observe evolution of a black hole as it wolfs down stellar
Halo of highly energized electrons around the black hole contracts dramatically during feeding frenzy. On March 11, an instrument aboard the International Space Station detected an enormous explosion of X-ray light that grew to be six times as bright as the Crab Nebula, nearly 10,000 light years away from Earth.

Magnetar Mysteries in our Galaxy and Beyond
Magnetar Mysteries in our Galaxy and Beyond
In a new Caltech-led study, researchers from campus and the Jet Propulsion Laboratory (JPL) have analyzed pulses of radio waves coming from a magnetar-a rotating, dense, dead star with a strong magnetic field-that is located near the supermassive black hole at the heart of the Milky Way galaxy. The new research provides clues that magnetars like this one, lying in close proximity to a black hole, could perhaps be linked to the source of "fast radio bursts," or FRBs.

XMM-Newton captures final cries of star shredded by black hole
XMM-Newton captures final cries of star shredded by black hole
Astronomers using ESA's XMM-Newton space observatory have studied a black hole devouring a star and discovered an exceptionally bright and stable signal that allowed them to determine the black hole's spin rate. Black holes are thought to lurk at the centre of all massive galaxies throughout the Universe, and are inextricably tied to the properties of their host galaxies.

Canada’s CHIME telescope detects second repeating fast radio burst
A Canadian-led team of scientists has found the second repeating fast radio burst (FRB) ever recorded. FRBs are short bursts of radio waves coming from far outside our Milky Way galaxy. Scientists believe FRBs emanate from powerful astrophysical phenomena billions of light years away.

Achieving goals in the lab and on the pitch
Senior Anthony Badea, a physics major and varsity soccer player, investigates the beginnings of the universe. Anthony Badea got hooked on physics during his senior of high school in Irvine, California. He used to fall asleep watching interviews and speeches by public figures in science like astrophysicist Neil deGrasse Tyson and string theorist Michio Kaku.

Citizen scientists help discover new exoplanet in ’habitable zone’
A new planet roughly twice the size of Earth has been discovered located within the "habitable zone"-the range of distances from a star where liquid water may exist on the planet's surface. A research team that included a UChicago graduate student confirmed the finding after volunteer citizens flagged a crucial piece of evidence in data from NASA's Kepler spacecraft.

TESS discovers its third new planet, with longest orbit yet
Measurements indicate a dense, gaseous, "sub-Neptune" world, three times the size of Earth. NASA's Transiting Exoplanet Survey Satellite, TESS, has discovered a third small planet outside our solar system, scientists announced this week at the annual American Astronomical Society meeting in Seattle.

Tiny satellites could be "guide stars" for huge next-generation telescopes
Researchers design CubeSats with lasers to provide steady reference light for telescopes investigating distant planets. There are more than 3,900 confirmed planets beyond our solar system. Most of them have been detected because of their "transits" - instances when a planet crosses its star, momentarily blocking its light.

Groovy young rock stars and the Holy Grail
Will a telescopic Census of thousands of planets help to pinpoint a new Earth? For Professor Jane Greaves, such a discovery will be the ‘Holy Grail' - the culmination of a career spent observing planets forming around young stars. At the heart of the study, interpreting data on raw material ‘remnants' from comet collisions around stars like the Sun will be the key to success.

Martian drill set for Antarctic climate mission
A drill originally developed to break through Martian rocks is set to be deployed to Antarctica on a mission which could help us understand the history of Earth's changing climate. A team of University of Glasgow engineers are heading to a British Antarctic Survey (BAS) research station named Skytrain Ice Rise on Thursday 3 January with a sophisticated drill they originally developed for use on future unmanned Martian rover missions.
