German nights get brighter — but not everywhere

The nights in the German federal states („Bundesländer") have been getting brighter and brighter - but not everywhere at the same rate and with one peculiar exemption: light emissions from Thuringia decreased between 2012 and 2017. This is the result of a recent study by scientists Chris Kyba and Theres Küster from the GFZ German Research Centre for Geosciences together with Helga Kuechly from "Luftbild…

Enduring ‘radio rebound’ powered by jets from gamma-ray burst

These images of the millimeter-wavelength light reveal details about the energy in the GRB's jets.... view more  Credit: ALMA (ESO/NAOJ/NRAO), T. Laskar; NRAO/AUI/NSF, S. Dagnello In the blink of an eye, a massive star more than 2 billion light-years away lost a million-year-long fight against gravity and collapsed, triggering a supernova and forming…

GPD’s sequel to its handheld Windows gaming PC is far more...

Chinese manufacturer GPD has carved out a niche for itself making some impressive portable PCs, and the firm – which produced the GPD Pocket that we recently reviewed and liked – is coming out with a sequel to its popular handheld Windows gaming PC. The GPD Win 2 is being fired up as a campaign…

An exoplanet loses its atmosphere in the form of a tail

A new study, led by scientists from the Instituto de Astrofísica de Canarias (IAC), reveals that the giant exoplanet WASP-69b carries a comet-like tail made up of helium particles escaping from its gravitational field propelled by the ultraviolet radiation of its star. The results of this work are published today in the journal Science. To detect the atmosphere of the giant exoplanet WASP-69b the scientists…

COSINE-100 experiment investigates dark matter mystery

The tank was later filled with liquid scintillator to tag cosmic ray muons. view more  Credit: Chang Hyon Ha New Haven, Conn. - Yale scientists are part of a new international experiment that challenges previous claims about the detection of non-luminous dark matter. Astrophysical evidence suggests that the universe contains a large amount…

Granite crystallizes at temperature 200 degrees lower than previously thought

IMAGE: The gradient of titanium in quartz is evidence that the mineral crystallized at a cooler temperature than had been previously believed. view more  Credit: Rensselaer Evidence from rocks in Yosemite National Park suggests that granite stored in the Earth's crust is partially molten at 500 degrees Celsius, nearly 200 degrees lower than had previously been believed. The finding, published online today in Nature, challenges long-held…

Tropical Cyclone Alcide’s rainfall observed by GPM Satellite

The Global Precipitation Measurement mission or GPM core satellite passed over the Southern Indian Ocean and analyzed the rainfall occurring in pre-season Tropical Cyclone Alcide. Tropical cyclone Alcide (03S), the first tropical cyclone of the 2018-2019 South-West Indian Ocean tropical cyclone season, has formed in the South Indian Ocean northeast of Madagascar. The Joint Typhoon Warning Center (JTWC) issued its first warning for 03S on…

A new kind of star

A new kind of star comes up from a study by SISSA's postdoctoral researcher Raúl Carballo-Rubio. In a piece of research recently published in Physical Review Letters, Carballo-Rubio has developed a novel mathematical model that combines general relativity with the repulsive effect of quantum vacuum polarization. The inclusion of this repulsive force allows describing ultracompact configurations of stars, which were previously considered by scientists not…
