Moon Dust Would Give Astronauts Lunar Hay Fever

Astronauts of the future spending long periods of time on the moon could suffer from bronchitis and other health problems by inhaling tiny particles of lunar dust, study indicates. Simulated lunar soil is toxic to human lung and mouse brain cells. Up to 90 percent of human lung cells and mouse neurons died when exposed [...]

Early Universe Cosmic Microwave Background 3D Printed

A 3D printed map of the oldest light in the universe has been created by researchers at Imperial College London, and you can download the files and your print your own baby universe. The cosmic microwave background is a glow that the universe has in the microwave range that maps the oldest light in the [...]

In the first major results of NASA’s Magnetospheric Multiscale (MMS) mission, a new study contains a groundbreaking look at the interaction between the magnetic fields of Earth and the sun. The Earth’s magnetic field presents an invisible but critical barrier which protects Earth from the sun’s magnetic field. That force drives a stream of charged [...]

More Celestial Neighbors Found By Dark Energy Survey

Eight more faint celestial objects hovering near our Milky Way galaxy have been discovered by scientists on the Dark Energy Survey, using one of the world’s most powerful digital cameras. Evidence suggests that they, like the objects found by the same team earlier this year, are likely dwarf satellite galaxies, the smallest and closest known [...]

A planet more like Earth than any other exoplanet yet documented has been discovered by NASA scientists. The planet is called Kepler-452b, and although it is 60 percent bigger than our planet, it has a year that’s about 385 days long. Kepler-452b orbits a G-type star, just like our own sun but 1.5 billion years [...]
