An international team of researchers from the United Kingdom and China has created droplet-based algal micro-reactors capable of aerobic or hypoxic photosynthesis...
Mars was once a wet planet, but it has lost most of its water through reactions that produce hydrogen. In standard models, molecular hydrogen produced...
Astronomers using ESO’s Very Large Telescope (VLT) have captured a beautiful image of a planetary nebula called the Skull Nebula.
This image, taken by...
Using two dimensionless fundamental constants, an international team of physicists has calculated the fastest possible speed of sound in condensed phases...
A team of astronomers from Australia and the United States has found that a halo of warm ionized gas surrounding the Large and Small Magellanic Clouds...
A type of meteorite called an enstatite chondrite has similar isotopic composition to terrestrial rocks and thus may be representative of the material...
Astronomers have observed cold, dense and high-velocity molecular gas outflowing from the center of our Milky Way Galaxy. The presence of this gas is puzzling,...
‘Oumuamua, a recently-discovered cigar-shaped object of extrasolar origin, is not made of molecular hydrogen ice after all, according to a new study...
Astronomers using NASA’s HERSCHEL (Helium Resonance Scattering in the Corona and Heliosphere) sounding rocket have obtained global images of the helium...
Physicists from the Jefferson Lab Hall A Tritium Collaboration have compared the nuclei of helium and hydrogen isotopes to each other to get a clearer...
In a paper to be published in the Astrophysical Journal Letters, astronomers from the University of Chicago and Yale University show that the odd properties...
Fast blue optical transients (FBOTs) share some characteristics with supernova explosions of massive stars and with explosions that generate gamma-ray...
A team of researchers at the Massachusetts Institute of Technology (MIT) has demonstrated that single-celled microorganisms such as Escherichia coli and...
Astronomers have discovered an ultra-massive white dwarf with a unique carbon-hydrogen mixed atmosphere. Named WD J055134.612+413531.09 (WD J0551+4135...
In 1947, American physicist Willis Lamb and his colleagues observed an incredibly small shift in the energy levels of the hydrogen atom as the atom’s...
Using data from NASA’s Spitzer Space Telescope, astronomers have found evidence that the heat in the atmosphere of KELT-9b, the hottest known transiting...
SN 2006gy, a superluminous supernova discovered in 2006, gained its exceptional brightness when a normal Type Ia explosion smashed into a dense shell of...
Enceladus, an ocean-harboring moon of Saturn, erupts a plume that contains gases and frozen sea spray into space. By understanding the composition of the...
