“#How ‘gravitational waves’ will change astronomy as we know it” Supermassive objects such as black holes and neutron stars warp spacetime around them, and interactions between these bodies can result in the formation of gravitational waves, similar to ripples in a pond. However, these waves, postulated more than 100 years ago, cannot be seen directly…

“#Astronomers just detected the oldest and most distant quasar ever” More than 13 billion light years from Earth, the quasar J0313–1806 radiates vast quantities of electromagnetic radiation. This body, formed just 670 million years after the Big Bang, is seen shining with 1000 times the total light produced by the Milky Way Galaxy. The supermassive…

“#Neutron star collision should have formed a black hole — but a ‘magnetar’ appeared instead” On May 22, 2020, light from a titanic explosion deep in space reached Earth. The energy seen by astronomers told of the collision of a pair of neutron stars, creating a kilonova explosion. This event, releasing more energy in a…

#Why the moon’s early magnetic field might be responsible for life on earth

“#Why the moon’s early magnetic field might be responsible for life on earth” The habitability of a planet depends on many factors. One is the existence of a strong and long-lived magnetic field. These fields are generated thousands of kilometers below the planet’s surface in its liquid core and extend far into space – shielding…
