For decades, scientists have speculated about the origin of the electromagnetic radiation emitted from celestial regions that host black holes and neutron stars—the most mysterious objects in the universe.
Stars form within giant clouds of gas and dust that pervade galaxies like our own Milky Way. This image depicts one such cloud, known as Orion A, as seen by ESA's Herschel and Planck space observatories.
After counting all the normal, luminous matter in the obvious places of the universe—galaxies, clusters of galaxies and the intergalactic medium—about half of it is still missing. So not only is 85% of the matter in the ...
An international team of scientists, including researchers at MIT, has come closer to pinning down the mass of the elusive neutrino. These ghost-like particles permeate the universe and yet are thought to be nearly massless, ...
Scientists have taken the temperature of a huge expanse of seafloor in the Arctic Ocean in new research by the U.S. Geological Survey and the Geological Survey of Canada. The study, published in the Journal of Geophysical ...
CO2 produced from burning fossil fuels is still mostly released into the atmosphere, adding to the burden of global warming. One way to cut CO2 levels is through carbon capture, a chemical technique that removes CO2 from ...
The cracked, uneven, jumbled landscape seen in this image from ESA's Mars Express forms an intriguing type of terrain that cannot be found on Earth: chaotic terrain.
We have seen intricate patterns that milk makes in coffee and much smoother ones that honey makes when stirred with a spoon. Which of these cases best describes the behavior of the hot gas in galaxy clusters? By answering ...
On 21 June 2019 the Spektrum-Röntgen-Gamma (Spektr-RG / SRG) spacecraft will be launched from the Kazakh steppe, marking the start of an exciting journey. SRG will be carrying the German Extended ROentgen Survey with an ...
A new, more accessible and much cheaper approach to surveying the topology and strength of interstellar magnetic fields—which weave through space in our galaxy and beyond, representing one of the most potent forces in nature—has ...
