The flash of a pulsar about 3,000 light-years from our solar system was caused by a ‘black widow’ binary consuming a smaller star. Intriguingly, a third companion star is orbiting the pair, which may have originated near the Milky Way’s center.

A new paper looks at marsquakes and what is causing them, which turns out to be magma moving. And Curiosity has found rocks it needs to go around. Then there is the weather on Mars
Researchers pouring through high-resolution Hubble images of galaxy clusters have found the gravitationally magnified light of a star that was shining just four billion years after the Big Bang, making this bright star the new record holder for the farthest ever spotted
Researchers use data from ESA’s Gaia telescope to discover that white dwarf stars have two different distributions both in how they move and how bright they shine.
Scientists propose using changes in the distance from the Earth to the Moon and measured by lasers as a way to detect the phenomenon of gravitational waves. Plus, JWST is working, ExoMars is at risk.
Today’s science stories run the gamut of the strange and the weird, with several black holes, the effects of space on astronaut blood cells, and how alligator mating dances added to solar science.
The science that dictates our planet is the exact same physics that affects our entire universe. Trying to understand everything around us is just as simple as taking into account all the forces and factors that interact to make everything we see.
Defying expectations, an ultramassive galaxy and many of its cluster companions had already formed most of their stars and become inactive only two billion years after the beginning of the Universe
A research team studying the Poás volcano in Costa Rica, a potential analog for early Mars conditions, finds microbes surviving in extremely harsh conditions. Plus, table-top matter-antimatter experiments, an exoplanet’s complex atmosphere, and how snails and squirrels can help us understand space.
NASA’s Curiosity rover has discovered carbon isotopes on Mars which (on Earth) are usually caused by the degradation of biological methane, leading scientists to examine other potential reasons for the molecules.
