Liquid carbon characterized using a free electron laser

From common soot to precious diamonds, carbon is familiar in many guises, but there have been little more than glimpses of carbon in the liquid form. Researchers at the FERMI Free Electron Laser (FEL) source have now not only generated a liquid carbon sample, but have characterized its structure, tracking the ultrafast rearrangements of electron bonding and atomic coordinates that take place as their carbon samples melt. "As far as I know, that is the fastest structural transition in condensed matter," says Emiliano Principi, principal investigator on the project.

A new way to search for dark matter reveals hidden materials properties

Liquid water at 170 degrees Celsius: X-ray laser reveals anomalous dynamics at ultra-fast heating

Using the X-ray laser European XFEL, a research team has investigated how water heats up under extreme conditions. In the process, the scientists were able to observe water that remained liquid even at temperatures of more than 170 degrees Celsius. The investigation revealed an anomalous dynamic behavior of water under these conditions. The results of the study, which are published in the Proceedings of the National Academy of Sciences (PNAS), are of fundamental importance for the planning and analysis of investigations of sensitive samples using X-ray lasers.

Physicists make electrical nanolasers even smaller

Researchers from the Moscow Institute of Physics and Technology and King's College London cleared the obstacle that had prevented the creation of electrically driven nanolasers for integrated circuits. The approach, reported in a recent paper in Nanophotonics, enables coherent light source design on the scale not only hundreds of times smaller than the thickness of a human hair but even smaller than the wavelength of light emitted by the laser. This lays the foundation for ultrafast optical data transfer in the manycore microprocessors expected to emerge in the near future.

Astronomy and Space news

Research reveals an enormous planet quickly orbiting a tiny, dying star

Thanks to a bevy of telescopes in space and on Earth—and even a pair of amateur astronomers in Arizona—a University of Wisconsin-Madison astronomer and his colleagues have discovered a Jupiter-sized planet orbiting at breakneck speed around a distant white dwarf star. The system, about 80 light years away, violates all common conventions about stars and planets. The white dwarf is the remnant of a sun-like star, greatly shrunken down to roughly the size of Earth, yet it retains half the sun's mass. The massive planet looms over its tiny star, which it circles every 34 hours thanks to an incredibly close orbit. In contrast, Mercury takes a comparatively lethargic 90 days to orbit the sun. While there have been hints of large planets orbiting close to white dwarfs in the past, the new findings are the clearest evidence yet that these bizarre pairings exist. That confirmation highlights the diverse ways stellar systems can evolve and may give a glimpse at our own solar system's fate. Such a white dwarf system could even provide a rare habitable arrangement for life to arise in the light of a dying star.

Five new giant radio galaxies discovered

With the help of citizen scientists, astronomers have detected five new giant radio galaxies (GRGs). The new GRGs have sizes ranging from 2.3 to 2.6 million light years, and have been identified at redshift between 0.28 and 0.43. The finding is reported in a paper published September 8 on the arXiv pre-print server.

Scientist searches for stellar phosphorus to find potentially habitable exoplanets

A Southwest Research Institute scientist has identified stellar phosphorus as a probable marker in narrowing the search for life in the cosmos. She has developed techniques to identify stars likely to host exoplanets, based on the composition of stars known to have planets, and proposes that upcoming studies target stellar phosphorus to find systems with the greatest probability for hosting life as we know it.

Can life survive a star's death? Webb telescope can reveal the answer

When stars like our sun die, all that remains is an exposed core—a white dwarf. A planet orbiting a white dwarf presents a promising opportunity to determine if life can survive the death of its star, according to Cornell University researchers.

How scientists around the world track the solar cycle

Every morning, astronomer Steve Padilla takes a short walk from his home to the base of a tower that soars 150 feet above the ground. Tucked in the San Gabriel Mountains, about an hour's drive north from Los Angeles, the Mount Wilson Observatory has long been a home for space science—it's Padilla's home too, one of the perks to his work as Mount Wilson's sun observer. Mount Wilson has several solar system sentinels; the telescope perched at the top of this tower keeps constant watch on the sun. Observers study the sun closely, so we can better understand the life and activity of our star.

Meteorite study calls into doubt a popular theory about the early solar system

It is generally accepted that the inner region of the early solar system was subject to an intense period of meteoric bombardment referred to as the late heavy bombardment. However, researchers have found evidence that suggests this period occurred slightly earlier than thought and was less intense but also more prolonged. Such details about this period could impact theories about the early Earth and the dawn of life.

Unraveling a spiral stream of dusty embers from a massive binary stellar forge

With almost two decades of mid-infrared (IR) imaging from the largest observatories around the world including the Subaru Telescope, a team of astronomers was able to capture the spiral motion of newly formed dust streaming from the massive and evolved binary star system Wolf-Rayet (WR) 112. Massive binary star systems, as well as supernova explosions, are regarded as sources of dust in the Universe from its early history, but the process of dust production and the amount of the ejected dust are still open questions. WR 112 is a binary system composed of a massive star in the very late stage of stellar evolution losing a large amount of mass and another massive star at the main sequence. Dust is expected to be formed in the region where stellar winds from these two stars are colliding. The study reveals the motion of the dusty outflow from the system and identifies WR 112 as a highly efficient dust factory that produces an entire Earth mass of dust every year.

Astronomers discover a 2-km asteroid orbiting closer to the sun than Venus

Solar cycle 25 has begun

In the past one and a half years, the sun has been rather dull: hardly a sunspot covered its surface, hardly a solar flare hurled radiation and particles into space. As observational data now show, for the last nine months solar activity has been slowly picking up again. Already in December 2019, our star passed its activity minimum, an event which occurs approximately every eleven years. This confirms predictions made by the Solar Cycle 25 Prediction Panel, an international panel of experts organized by NASA and NOAA (National Oceanic and Atmospheric Administration), in March last year. The panel, whose members include Robert Cameron from the Max Planck Institute for Solar System Research (MPS) in Germany, expects the sun to be as tame in the now beginning solar cycle 25 as it has been in the previous eleven years.
