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
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.

Mars 2020 - geology and the conquest of space
Cathy Quantin-Nataf, Gilles Dromart and Gilles Montagnac of the Laboratoire de Géologie de Lyon (LGL-TPE) are members of a research team developing one of the instruments that will go aboard the rover of the Mars 2020 Mission: the SuperCam. Watch live as NASA's next rover, Mars 2020, is built and tested in the Spacecraft Assembly Facility at the agency's Jet Propulsion Laboratory in Pasadena, California.

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.

Researchers honoured in Québec Science list of top discoveries
McGill researchers once again figure prominently in Québec Science magazine's annual list of the top 10 scientific discoveries in Quebec.  For 2018, four of the selected discoveries were led by McGill-affiliated scientists.

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.

Anna Frebel is searching the stars for clues to the universe’s origins
MIT astronomer and writer investigates ancient starlight and shares her excitement about the cosmos. In August 2002, Anna Frebel pressed pause on her undergraduate physics studies in Germany and spent her entire life savings on a plane ticket to take her halfway around the world, to a mountaintop observatory just outside Canberra, Australia.
