The rare isotope iron-60 is created in massive stellar explosions. Only a very small amount of this isotope reaches the earth from distant stars. Now, a research team with significant involvement from the Technical University of Munich (TUM) has discovered iron-60 in Antarctic snow for the first time. The scientists suggest that the iron isotope comes from the interstellar neighborhood.
Japanese researchers show how a holographic tabletop experiment can be used to simulate the physics of a black hole. This work may lead the way to a more complete theory of quantum gravity that harmonizes quantum mechanics and relativity.
Lithium fluoride crystals have recently been used to register the tracks of nuclear particles. Physicists from the Institute of Nuclear Physics of the Polish Academy of Sciences in Cracow have just demonstrated that these crystals are also ideal for detecting tracks of high-energy ions of elements even as heavy as iron.
A team of astronomers led by Anne-Marie Lagrange, a CNRS researcher, has discovered a second giant planet in orbit around β Pictoris, a star that is relatively young (23 million years old) and close (63.4 light years), and surrounded by a disk of dust. The β Pictoris system has fascinated astronomers for the last 30 years since it enables them to observe a planetary system in the process of forming around its star.
An experiment to test a popular theory of dark energy has found no evidence of new forces, placing strong constraints on related theories.
University of Arizona researchers are using the Catalina Sky Survey's near-Earth object telescopes to locate the optical counterparts to gravitational waves triggered by massive mergers.
If our eyes could see gamma rays, the Moon would appear brighter than the Sun! That's how NASA's Fermi Gamma-ray Space Telescope has seen our neighbor in space for the past decade.
A new study provides the most accurate estimate of the frequency that planets that are similar to Earth in size and in distance from their host star occur around stars similar to our Sun.
New research from astronomers at the University of Washington uses the intriguing TRAPPIST-1 planetary system as a kind of laboratory to model not the planets themselves, but how the coming James Webb Space Telescope might detect and study their atmospheres, on the path toward looking for life beyond Earth.
Astronomers have uncovered a new way of searching for life in the cosmos. Harsh ultraviolet radiation flares from red suns, once thought to destroy surface life on planets, might help uncover hidden biospheres. Their radiation could trigger a protective glow from life on exoplanets called biofluorescence, according to new Cornell University research.
