The chemical nitrous oxide, or laughing gas, may be a biosignature of life, according to astrobiologists. Chemical compounds in a planet’s atmosphere that could indicate life, called biosignatures, typically include...
Both NASA's James Webb Space Telescope and the Hubble Space Telescope captured views of a spacecraft smashing into a small asteroid in an experiment to deflect asteroids. These observations of...
A dwarf galaxy now seen in the constellation Sagittarius caused mysterious ripples in the Milky Way hundreds of millions of years ago. Scientist from Lund University in Sweden used the...
The Milk Way is spinning about 24 percent slower because of dark matter. This is the first time this slowdown has been definitively measured. Astrophysicists have predicted this slowdown for...
Astronauts who go on long voyages in space in the future may suffer impairment in their emotional recognition. A study showed that prolonged weightlessness slowed down a person's ability to...
The star S2 orbits the supermassive black hole at the center of the Milky Way in a rosette pattern as predicted by Einstein. The observations were made by the European...
The universe is not expanding equally in all directions, says a study by scientists from the Universities of Bonn and Harvard. If this is true, there are huge implications because...
The urea in astronauts’ urine can act as a plasticizer for the concrete used to build moon base structures. Researchers at NASA, the European Space Agency (ESA) and its Chinese...
Scientists call large exoplanets that have extremely low density “cotton candy” planets. These super-puffs, as they are also referred to, may actually have rings. This theory was proposed by scientists...
A property of the neutron particle may help clarify why matter and anti-matter didn’t cancel themselves out after the Big Bang that lead to the creation of the universe. Researchers...
