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.

More stable light comes from intentionally ’squashed’ quantum dots
Exploiting new 'strain engineering' approach produces highly stable, narrow linewidth light from individual quantum dots The squashed dots also show compatibility with virtually any substrate or embedding medium as well as various chemical and biological environments.

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.

Shows single atoms can make more efficient catalysts
Detailed observations of iridium atoms at work could help make catalysts that drive chemical reactions smaller, cheaper and more efficient. Catalysts are chemical matchmakers: They bring other chemicals close together, increasing the chance that they'll react with each other and produce something people want, like fuel or fertilizer.

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
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.

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.

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.

Excitons pave the way to more efficient electronics
After developing a method to control exciton flows at room temperature, EPFL scientists have discovered new properties of these quasiparticles that can lead to more energy-efficient electronic devices. They were the first to control exciton flows at room temperature. And now, the team of scientists from EPFL's Laboratory of Nanoscale Electronics and Structures (LANES) has taken their technology one step further.

Revealing Hidden Spin: Unlocking New Paths Toward High-Temperature Superconductors
Berkeley Lab researchers uncover insights into superconductivity, leading potentially to more efficient power transmission In the 1980s, the discovery of high-temperature superconductors known as cuprates upended a widely held theory that superconductor materials carry electrical current without resistance only at very low temperatures of around 30 Kelvin (or minus 406 degrees Fahrenheit).

DNA design that anyone can do
Computer program can translate a free-form 2-D drawing into a DNA structure. Until now, designing such structures has required technical expertise that puts the process out of reach of most people. Using the new program, anyone can create a DNA nanostructure of any shape, for applications in cell biology, photonics, and quantum sensing and computing, among many others.

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.

Our cutting-edge technology platforms are key enablers of research at the FMI. One of the biggest of these, with the largest number of users, is the Facility for Advanced Imaging and Microscopy (FAIM). To find out more about the facility, and microscopy in general, we spoke to the joint heads of FAIM - Christel Genoud, who is responsible for Electron Microscopy, and Laurent Gelman, responsible for Light Microscopy.

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.
